DLP is the abbreviation of "Digital Light Procession", which means digital light processing, which means that this technology must first process the image signal digitally, and then project the light. Then someone said that after reading the concept, they still have a little understanding, don't worry, wait for me to explain. To be more specific, the working principle of DLP projection technology is that the light source hits the light on the lens to obtain usable parallel light, the parallel light passes through the color wheel to obtain a uniform rectangular spot, and then the core component of DLP projection technology is the digital micromirror chip. DMD (Digital Micromirror Device) processing, and finally hit the light on the projection lens, and get the projection we need through the lens. It is said that dlp projector portable is good, what's so good about it? Compared with several other projection technologies on the market, DLP mainly has the following advantages: 1. The tight gap between the micromirrors in the DLP makes the projected image very delicate and has a very high resolution capability. Projection using DLP technology, the picture quality is delicate 2. The

Save space If the living area is small and you can't wait to use every inch of space, portable projector 1080p is more space-saving. The small body, whether

What can a Portable Projector do? Many friends have asked Xiaobian about this question, and some friends who have bought projectors before may only use one or two simple functions of Smart Portable Projector. This time Xiaobian will take a closer look with you here. , How many functions can a projector have? Here, I will take the Y7 smart portable projector as an example and list it for you. First of all, everyone must understand that the projector is divided into three types: multimedia version, same-screen version and Android version (which one do you have? You can find the corresponding version and jump to see). 1. Multimedia version (basic version), mainly to simply read the video, picture, music, text in U disk or TF card, and use its own hardware interface to connect external devices. The text reading of the multimedia version is limited to TXT format, and cannot read PPT, Excel, and word files. HDMI can be mainly used for external devices, such as set-top boxes, computers, PSP game consoles, cameras and other devices with HDMI signal output. As a simple display, the AV video interface is the same, mainly connected to set-top boxes, DVDs with red A device with yellow and white three-color interface signal output. In addition, there are also some mini smart portable projector wifi with VGA interface, SD card slot, etc., which are also used for external computer equipment and memory cards.

Only by combining the family situation and your own needs can you choose a projector that is more suitable for you. Projector buying tips 01 Resolution

In general, the brightness of a projector is a parameter standard, but in fact, there are three brightness standards for projectors: light source brightness, projection brightness, and actual viewing brightness. This has to start with the principle of the projector. The imaging principle of the projector is that the light machine emits light, which is processed by the chip and projected onto the curtain or wall, and then reflected to the human eye. The brightness of the light source of the projector is the brightness emitted by the optical machine from the machine. This brightness value is the highest, but it has no reference significance at all. After all, we will not stare at the optical machine when looking at the picture, which is very harmful to the eyes. Can't do that. The projection brightness is the brightness of the picture on the wall measured after the projection light is projected on the wall. This brightness is relatively low in value, but it is indeed the brightness displayed by the picture, so the reference significance is relatively large. The actual viewing brightness is the brightness of the projector image entering our human eyes after the diffuse reflection of the wall/curtain. This brightness value is further reduced, and is greatly affected by the surrounding ambient light, so it is unlikely to be taken out as a reference. value of . Generally speaking, for our ordinary consumers, the projection brightness of the projector is of great reference significance, and the numerical unit is ANSI, so we can just look f

Screencasting is a question often asked by novice players, so what are our commonly used frequency casting methods? How does it work? First of all, we need to understand two concepts, the first is the same screen, and the second is the projection screen. Same screen: As the name implies, the content on the terminal device such as the mobile phone screen is completely synchronized to the display device. Here we only talk about professional home theater projection. (Simple display device without system) After the above description, we know that screen projection must be realized from the playback source. The method is to install the same screen software on the mobile phone and the box or the player under the same local area network, and open the software. The software connected to the box can display the screen of the mobile phone through the box to make the projection present, but the point is this, the presentation is presented, and even sliding down the screen of the mobile phone is not smooth, do you think you can still play video? So it's not realistic for you to use it. Next, let's introduce mobile phone screen projection. Screencasting: It refers to casting the specified video on your mobile phone without preventing your mobile phone from doing other things. For example, if you use your mobile phone to cast a movie, then while watching the movie on the big screen, you can still chat with Q, browse the circle of friends, and play mobile games. There is no mutual influence between the mobile phone and the projector. So how to achieve it? In fact, it i

We first clarify what kind of projector can be side-projected. The projector with horizontal and vertical keystone correction can be projected from the side, and the projected image from the side must be left or right trapezoid. If you put it on a side table or a small seat, the projected image is low, and the operation at this time is either Change the placement surface with a suitable height, or adjust the height of the front of the projector, then the latter is definitely a vertical trapezoid when projected obliquely upward, so it is best to have both horizontal and vertical trapezoid correction. The angle that can be projected sideways is determined according to the parameters. Professional home theater projection has a 30° angle, that is, the angle between the projection lens and the center line of the screen can be adjusted to a regular rectangle through correction within this range, so how about side projection. We are going to talk about it in detail. From the perspective of professional installation, the projector does not allow any correction. Why does the side projection lose the picture, because the side projection uses keystone correction or four-corner correction, and the deformed picture is stretched to the position you want by digital means, then it must be It will cause pixel compression to lose the picture and cause local blurring. It is worth noting that the machine without four-corner correction is not very easy to adjust into a rectangle. In a special case, a machine with a wide range of left and right lens shifts can reduce the side projection angle and reduce the compression area. Friends who have side projection needs can choose. Side projection creates light and shadow between the original image and the corrected image due to keystone correction. If you want to cast sideways, then the shortcomings must be accepted. Side shot is the last resort, there is no wa

1.Is it better for children to watch a projector or watch TV First of all, it should be stated that whether the baby is watching TV or watching a projector, if the time is long, it will damage the eyes and is not conducive to the development of the baby's eyesight. However, because the projector enters the eyes after diffuse reflection, which is close to natural light, and the TV is directly reflected into the eyes, the damage to the eyesight of the TV is greater than that of the projector, so it is better for the baby to watch the projector than to watch the TV. Whether it is a TV or a projector, the light that stimulates the eyes for a long time will have a certain impact on the baby's vision. Young children are not recommended to watch TV, projectors or mobile phones. In the case of unavoidable circumstances, the projector is less harmful than the TV. 2.How old can a baby watch TV Babies generally can watch TV for a while after one year old, because the disappointment face develops better after one year old, watching TV at this time will not cause damage to the baby's eyes. But you can't watch it for a long time, and don't watch it for more than ten minutes at a time. In order to protect the baby's eyesight, it is necessary to take the baby to get close to nature when the weather is good, and let the baby's eyes relax through the natural scenery, so as to correct problems such as poor vision after watching TV.

Professional home theater projection, most non-micro-projection projectors do not have a system, how to understand without a system, just like our computer monitor, it needs a signal source to give it a signal to display. The host is equivalent to the signal source. They are connected by HDMI cable. Then in the projection system, what will give the signal and act as the playback source, our PC, network set-top box, network Blu-ray player, Blu-ray disc player, PS, NS, XBX game consoles and other devices that can output audio and video can be this signal source, so to perform functions such as mobile screen projection, etc. are not directly interacting with the projection itself, but interacting with our signal source. The source is transmitted to the projector for development, and the pico-intelligent projection has this signal source built into the machine. The biggest difference between the two of them is the external signal source and the built-in signal source.

There are various reasons why using a projector for everyday viewing is either a great idea or a not so great idea. It depends on the room that the projector may be located in, the people watching, and much more! Pros of Using a Projector for Everyday Viewing Undeniable Price Advantage Over Large-Television Options If your goal is big, there`s no question that projectors have the advantage. Impressive User Experience The big screen just makes video more compelling. Whether it`s news, sitcoms, or a Blockbuster movie, having a huge screen to watch all of your [normal" content on makes it all feel more engaging. It takes a part of your life–a weekly ritual of watching your favorite shows, perhaps, and elevates that experience to something more substantial. One surprising advantage is that the larger screen is actually easier on the eyes since it takes up more of your visual field, mimicking the way light in the real world works. If you watch a lot of TV and suffer from eye strain, moving to a projector may actually make those issues go away. Cons of Using a Projector for Everyday Viewing Projector Cons Projectors Have Higher Operating Costs Driven by the Bulb Life Typical projector bulb lives run around 2000 hours, and that will go quickly if you`re using the projector for every-day TV watching.

Projectors offer an unparalleled option of screen size at their price point, with many 100-inch screen projectors coming in at well under the price of a 55-inch or 65-inch television. But what about for content other than movies and prestige-TV shows? What about normal every-day use: your cable-TV sitcoms and favorite news channels? Are projectors good for that too? You can absolutely use a projector for normal, everyday TV watching. It won`t hurt the projector (though it may run the bulb life down faster), and it may lead to a better overall TV-watching experience, at a lower price-point than most larger Televisions. Not only that, but it`s also an undeniable flex to be able to turn your nose up at the Jones`s [curved-65-inch this" or [Samsung quantum dot that." A projector might be expensive, but it`s no more expensive than even a very large TV. It has much more of a wow-factor in a space, but it`s worth discussing some of the pros and cons in detail, including the fact that projectors are much better for your eyes.

Depending on the ports available on your laptop, you may or may not need an adapter. Most projectors include an HDMI input port, so if your laptop has a full-size HDMI port, you probably won't need an adapter. The same is true if your projector has a VGA input and your computer has a VGA port. In most other cases you will need an adapter. Here's a description of the types of ports your laptop may have and the adapter you'll need to get, if any: HDMI port: If your laptop has a full-size HDMI port and your projector has the same type of port, you don't need an adapter. HDMI is the easiest way to connect a projector to a laptop. Mini HDMI Ports: Also known as HDMI type-c, they are functionally the same as HDMI, just smaller. You can use a cable or adapter with HDMI on one end and HDMI type-c on the other. DisplayPort: These are more common on desktop video cards, but your laptop probably has one. If so, then you can use an HDMI to DisplayPort cable or HDMI to DisplayPort adapter. USB-C: If your laptop uses USB-C to output video, you'll usually need to purchase a docking station that includes an HDMI port or a USB-C to HDMI adapter. However, some projectors do support USB-C video input, in which case you can connect your laptop directly to the projector via a USB-C cable. VGA: This is an older video connector limited to 640x480 resolution. If your laptop and projector both have VGA ports, you can connect them with a VGA cable without the need for an adapter. However, you'll also need to use another method to send the sound from the laptop to

1. What does ANSI lumens mean? To put it simply: ANSI lumens, formulated by the American National Standards Institute (ANSI), that use ANSI lumens to represent the light output of the projector, has been generally accepted internationally. Professional explanation: ANSI lumens refers to the main technical indicators of the projector. "Light out" is usually expressed in terms of luminous flux. Luminous flux is the ability to describe the strength of the visual response generated by the radiation of the light source per unit time, and the unit is lumens. The international standard unit for projectors to express luminous flux is ANSI lumens, which is a method for measuring the luminous flux of projectors developed by the American National Standards Institute. It has been generally accepted internationally. 2. What does brightness mean Simply put: it is the light emitted by the projector optical machine. Professional explanation: Projector brightness is an indicator that defines the brightness of the projector's image, in fact it is determined by the projector's light output. However, at present, there is no unified standard for manufacturers in the world, so there are different names such as brightness, illuminance, light output, etc. in each manual, and there are many units, including lux, lumens, peak white lumens, ounces ( ANSI) lumens, etc. In fact, in optical theory, there are strict definitions and units for the physical

If the "No Signal" message appears, try the following solutions: 1.Press the Source button on the projector repeatedly to cycle through the available sources. Wait a few seconds for an image to appear. 2.Turn on the connected computer or video source, and press its play button to begin your presentation, if necessary. 3.Check the connection from the projector to your video sources. If you are projecting from a laptop computer, make sure it is set up to display on an external monitor. If necessary, turn the projector and the connected computer or video source off and then on again. If the other solutions do not solve the problem, reset all of the settings using the Reset menu.

Thanks to the features of large-screen viewing, portability, and rich functions, smart portable projectors have become the first choice for users in home viewing and modern office scenarios. As a new face in the projection market in recent years, many people do not know much about the category of laser TV, which leads to certain doubts when purchasing. What is the difference between a laser TV and a projector? Should I buy a laser TV or a projector for home use? In this issue, we will talk to you about the differences between projectors and laser TVs from three aspects: light source and light resistance, composition and installation distance. 01 Three major differences between projectors and laser TVs Despite the name Laser TV, it's not a TV. In essence, laser TV belongs to a sub-category of projectors, also known as ultra-short-throw laser projection. Light source and light resistance Light sources are an integral part of projectors and laser TVs. The light source of projectors is generally divided into two types: traditional light bulbs and LED light sources; the light source of laser TVs is traditional solid-state lasers. The advantages and disadvantages of different light sources are also very obvious: "laser light sources" have higher brightness, longer life, and of course more expensive prices; "tra

For many netizens who do not understand projectors, the off-axis of projectors is a relatively new concept. Projector off-axis is very important for other installations such as home projectors or office projectors. There will be a big problem. The following is a brief introduction to what the off-axis of the projector means, and what is the use of this function. Projector off-axis function introduction: The projector off-axis function means that the projector screen will be presented on the same level as the projection lens; that is, the bottom edge of the projection screen and the projector lens will be on the same level. So far, the off-axis projector is also called a stand-free projector. The off-axis function of the projector is divided into 100%, 80% or no off-axis. For a projector with a 100% off-axis, the screen will be kept at the same level as the lens; a projector with an off-axis of 80% will have some low screen images. on the lens. The off-axis function of the projector: The off-axis function of the projector is mainly for the convenience that the projector can be directly projected on the desktop, so that it is convenient for the user to use directly. At present, most projectors support 100% off-axis, and only some LCD home projectors may have 80% off-axis. The projector without the off-axis function needs to be used with a bracket. When it is used on the desktop, half of the screen will be on the desktop and half of the screen will be on the wall. You can refer to the two pictures below.

The projector is a sophisticated electronic instrument, so its use must have certain taboos, so what are the taboos for the use of the projector? How can we use the projector so that we can avoid these situations? The following will describe in detail. 1. Do not switch the projector on and off frequently Reason: Every time the projector is turned on and off, it will generate a large inrush current, which will impact the components inside the projector. Greatly reduces the life of the projector. Suggestion: Turn off the machine after turning it on or turn it on again after turning it off. There needs to be a period of time in between, and the interval time should not be less than 10 minutes. If possible, try to control it to more than half an hour. 2. Do not disconnect the power directly after the projector is turned off Reason: After the projector has been used for a period of time, there will be very high heat inside, especially the lamp of the projector. If the power supply is directly disconnected after the shutdo

In Classrooms Projectors are used in schooling area for describing a topic. With the aid of a projector, videos or photograph become more enjoyable and children can easily learn by fun way. Further, we can easily zoom-in or zoom-out the image to clear the vision and to search minor points. In Companies Projectors are used in big MNC`s and enterprises for meeting, presentation and conference purposes.

There are many ways to extend the lamp life of a projector. Use these guidelines to get the most out of your new lamp. Operate No More Than 3 to 5 Hours at a Time Extensive use without a cool down period can quickly reduce the life span of a projector and bulb. It's the fastest way to burn out your equipment. Clean Intake Vents, Exhaust Vents and Air Filters Regularly All projectors feature intake and exhaust vents to help reduce overheating, There are also air filters available to protect delicate circuitry from debris. Clean the vents and air filters as often as your user manual instructs or at least once every three months to ensure long-lasting operation. Operate the Device in a Clean, Dust-Free Environment With Good Airflow Dust can clog intake and exhaust vents and restrict airflow in circuitry which can lead to overheating. Whenever possible, only use a projector in dust-free areas. Clean surfaces before setting up or mounting your projector to reduce debris near your device. If you must use the projector in less-than-ideal conditions, clean the vents and air filters more often than suggested. It`s equally important to ensure you use the projector in open areas that improve airflow. Avoid Frequent Power Cycles Every time you turn on the projector, the lamp strikes and reshapes the electrodes which slowly reduces the bulb`s lifespan. It`s better to leave it running if you need to take short breaks over hours of use. Handle Bulbs With Care

Incompatible parts and mishandling can reduce the life-cycle of projector lamps and replacing them can be costly. It`s essential to understand how to choose the correct replacement. In this projector lamp buying guide, we`ll discuss how to tell when it's time for a replacement and ways to increase the life expectancy of your new projector lamp bulb. How to Tell When to Change a Projector Bulb Most projector lamps last between 1,500 and 2,000 hours, but some can last up to 5,000 hours. Most projectors will need one to two bulb swaps during this time. Unlike other bulbs that go out once expended, the high-pressure mercury and xenon used in projector lamps cause bulbs to dim over time. Once the lamp light is at about half its original luminescence, it`s time to replace it. You can continue to use the bulb until complete failure, but doing so impacts image quality. Check how many useful hours your lamp has left in the menu options of the projector. User manuals have specific steps for this process. Manufacturers and product testers judge life expectancy based on a bell curve of a bulb. Most projector lamps come with a 90-day or 3-month warranty instead of a warranty that reflects its rated life span. Lamp Replacement Options The easiest way to get a compatible bulb is to buy an original equipment manufacturer (OEM) projector lamp replacement module designed for the projector model in question. Some companies make copy bulbs for cheaper alternatives. Get a b

Projector purchase After learning about projectors, the specs don't tell you much when shopping for a projector other than overall brightness, and projectors with similar specs often show drastically different results. Each user's location and room brightness are different. The following parameters are for your reference only. 1. Brightness. Nowadays, many users will choose high-brightness projectors. In fact, if they are viewed in a dark environment, too bright projectors will cause eye discomfort. 2. Contrast ratio is an important indicator for projectors, it is the difference between the darkest black and the brightest bright spot that the projector can reproduce, the data on general projector specifications is used to compare different brands of projectors, so Better to read more reviews. 3. Color gamut. A projector's color gamut describes the range of colors that can be reproduced. A good 1080p home theater projector meets the full Rec.709 color gamut created for HD content. Better 4K/UHD projectors meet or come close to the full DCI-P3 specification currently used for 4K content. 4.D65 color mode. Most projectors offer a factory-adjusted picture mode with different color profiles and brightness. Better home theater projectors have a color model that strictly adheres to these industry standards, including a neutral gray "D65" color temperature on white. 5. Fan noise. Fan noise specs can help compare projectors, but the numbers don't reflect the pitch of the noise, which affects how disruptive it

Projection Display Technology Liquid Crystal Display (LCD). Most modern LCD imagers have resolutions up to 1920x1200, and home theater models typically use 1920x1080 (1080p) imagers. Higher resolutions are possible, but not common. This projector can accept and display ultra-high-definition video signals, but the actual number of pixels on the screen is only half of the 8.3 million pixels in the signal. LCoS is a variant of LCD technology. Commonly used LCoS imagers have reached 4K resolution and can be switched at up to 120 Hz, which enables functions such as 3D, frame interpolation and pixel-shifting Ultra HD. However, at 120 Hz, they cannot do pixel-shifted UHD and 3D at the same time. LCoS is generally considered to have the best natural contrast and black levels of all digital projection technologies. DLP (Digital Light Processing) is the latest digital projection technology and one of the most popular today. DLP can provide true UHD (3840x2160) resolution. DLP projectors use one or more electromechanical imaging devices called DMDs, or digital micromirror devices. These tiny pixel-sized mirror arrays are up to 8.3 million in a 4K-resolution DMD just 1.38 inches wide.
