Filling the gap among the DLP market? Will the LCD projector era come once again?

"If the supply chain pattern of DLP light valve does not improve, both single-panel LCD and 3LCD will have more opportunities!" This is the "judgment"got from a senior executive of intelligent projection factory who did not want to be named recently! And how do you think about it? Please leave a message in the dialog box at the lower right corner!

Who has more market power in single LCD versus 3LCD?

Although 3LCD has "three-panel performance advantage" in the intelligent projection market, it also has the disadvantages of "three-panel imaging system is more complex", volume control is more difficult and cost is much higher for the moment. For the intelligent projection market, which is highly focused on price competitiveness, 3LCD can only become a "beneficial supplement to the high-end" for the time being, rather than the mainstream.

As for the single-panel LCD, althoug its disadvantage of color average due to its physical principle,but because of the constant changes in technology in this field,it has become a winner on audience scale without any doubts! To meet the basic needs of consumers for intelligent projector in the appearance, version varieties, functional diversity, gamut and brightness aspects on a large scale!

Does Contrast Ratio Matter With Projectors?

Contrast ratio—the ratio between the brightness of the brightest white a projector can produce and the brightness of the darkest black—always matters, but the rating for the projector usually won't. All other things being equal, a higher contrast ratio produces more vibrant, eye-catching color, more shadow detail in dark areas on the screen (most important for video and film), and a more dramatic sense of three-dimensionality in two-dimensional photorealistic images. 

However, contrast ratings are based on measurements in a dark room, so they don't tell you much about viewing in ambient light, where the darkest black you can get depends on how much light there is in the room. A projector that delivers a high contrast ratio in a dark room because of unusually dark blacks will deliver much lower contrast in ambient light, and a brighter projector that also has a higher black level in the dark will do poorly in a home theater but do well in a living room or office, where the high black level won't be noticeable, while the higher brightness will let it stand up better to the ambient light.

Comparing contrast-ratio specs is somewhere between challenging and pointless. Different manufacturers use different approaches to measuring contrast, and some even measure it differently for different models. There are also other factors—including video processing and auto-irises that change image brightness based on the content of the image—that increase your subjective sense of how good the contrast is but don't affect objective measurements. The best way to find out how good the contrast is for any given projector—short of seeing it yourself—is to look for reviews that discuss contrast in different settings.

Which Imaging Technology Is Best in a Projector?

Today's projectors are based on one of four imaging technologies: digital light processing (DLP), liquid-crystal display (LCD), liquid crystal on silicon (LCOS), and laser raster. (Don't confuse laser raster projectors, which actually draw the images using lasers, with the much more common models that simply use lasers as a light source for another imaging technology, like DLP or LCD chips.)

Most DLP projectors and some LCOS-based pico (aka pocket-size) projectors—including both data and video models—project their primary colors sequentially rather than all at once. This can lead to rainbow artifacts, in which bright areas on the screen break up into little red-green-blue flashes for some people when they shift their gaze or when something moves onscreen. Those who are sensitive to this effect can find it annoying, particularly for long viewing sessions.

LCD projectors are free from rainbow artifacts, but they tend to be bigger and heavier than comparable DLP models. Standard-size LCOS projectors, also rainbow-free, offer the best-quality images, but they tend to be bigger and heavier than either DLP or LCD projectors, as well as far more expensive. There aren't many laser raster projectors, so it's hard to make general statements about them. But the one clear advantage of using a laser is that the image doesn't require focusing.

What Kind of Light Source Is Best in a Projector?

There's a growing trend in projectors of moving from using lamps as light sources to using LEDs and lasers. For the moment, at least, there are advantages to each choice. 

LEDs and lasers maintain a higher percentage of their initial brightness for longer. All light sources lose brightness over time, but lamps generally lose a large percentage in the first 500 hours of use, and decline slowly after that. LEDs and lasers tend to lose brightness more evenly over their entire lifetimes.

The initial price for a lamp-based projector will be lower, but the total cost can be higher if you keep it long enough to need a replacement for the lamp. If you plan to replace your projector with every new jump in resolution or other image technology, buying a series of lamp-based projectors will be more cost-effective. But if you plan to keep your projector as long as it works, the better buy will be an LED, laser, or hybrid model that won’t need an expensive lamp replacement. 

What Is a Short-Throw Projector? Do You Need One?

If you want to cast a large image at a short distance from the screen, either because the room itself is a little small or to minimize the bother of people getting in front of the projector and casting shadows, you’ll need a short-throw or ultra-short throw projector. There are no universally accepted definitions for what counts as “short” or "ultra-short," but most short-throw projectors can cast an image about 6.5 feet wide from 3 to 6 feet away, while ultra-short-throw projectors generally need less than a foot. By comparison, most projectors with standard throws need to be roughly 9 to 13 feet away from the screen for the same image size, and long-throw projectors have to be even farther away.

The downsides of short-throw (and especially ultra-short-throw) projectors are that they are more expensive than traditional models with standard-throw lenses, and they are more likely to have noticeable variations in brightness or focus across the image. Ultra-short-throw models also require a particularly flat and stable screen. Even slight variations in the surface can distort the image and affect focus.

Does Your Projector Need Built-In Audio, or 3D Support?

Not all projectors have audio capability, and for those that do, the audio is sometimes all but useless—particularly with highly portable models. If you need sound for your presentations or for watching video, make sure that the projector has built-in audio that’s clear enough and loud enough to meet your needs. If not, consider using a separate sound system—often a good idea for home theater or home entertainment in any case—or powered external speakers. If you already have Bluetooth speakers, check whether the projector supports Bluetooth.

Then there's 3D. Showing images in 3D for educational, business, and home applications seems well past the boomlet it enjoyed a few years ago. But if you're a fan of 3D movies or have an application that requires 3D, it's still easy to find projectors that support it. 

Several 3D technologies are available, so make sure any 3D projector you consider will work with the 3D source you want to use. A “3D-ready” designation usually means it will work only with 3D generated by a computer. If you have a collection of 3D Blu-ray discs, the designation to look for is usually Full HD 3D. And before you go shopping for 3D glasses, be sure to check which kind the projector supports. There are several types, including some proprietary versions.

Do You Need a Portable Projector?

Consider how portable the projector needs to be. You can find portable projectors with sizes and weights ranging from small and light enough to fit in a shirt pocket to large and massive enough to be suitable only for a permanent, usually mounted, installation.

If you want a data projector to carry to business meetings for presentations, or a home entertainment or gaming projector to take to a friend's house or set up in your backyard for a movie night, be sure to pick an appropriate size and weight. If you'll be away from power outlets, check that the projector’s battery life is long enough for your needs.

What Resolution Is Enough in a Projector?

Projectors can scale images up or down, but that's best avoided, since it can distort the image. For any projector resolution up to and including WUXGA (1,920 by 1,200 pixels), you should match the projector’s native resolution (originally defined as the number of physical pixels in the projector's display) to the source you plan to attach it to most often, whether that's a computer, video equipment, or a game console. For projectors with 4K ultra-high definition (3,840 by 2,160 pixels), the calculation is a little different.

Current projectors built around 3,840-by-2,160 imaging chips are still too expensive for most applications. The affordable alternative takes advantage of a technique called pixel shifting. It uses a native 1,920-by-1,080 chip, generates more than one set of pixels for each frame in the video stream, and shifts the position for each set. The result is more pixels per frame on screen than are on the chip. Two sets doubles the number of pixels; four sets quadruples the number to a full 3,840 by 2,160. When done well, just doubling the number of pixels can deliver images that are indistinguishable from quadrupling them, at least at normal viewing distance from the screen.

Even 1080p projectors that can accept 4K UHD input handle it reasonably well. Thanks to the higher resolution having exactly four times as many pixels as 1080p, the only loss in quality from scaling the image down will be the equivalent of a slightly soft focus. If the projector also supports HDR10 (the high dynamic range, or HDR, version that's on discs and some streaming services, including Netflix) or HLG HDR (also supported by some streaming services), it can give you the advantage of HDR for improving image quality, even with 1080p resolution.

If you plan to show data images, you should consider the level of detail in the images. For a typical PowerPoint presentation, SVGA (800 by 600 pixels) may be good enough, and an SVGA projector will be much less expensive than one with a high

Which Widescreen Format Is Most Important in Your Projector?

Most projectors today offer native resolutions that qualify as widescreen formats. You'll generally want to match the aspect ratio (ratio of image width to image height) of the projector's resolution to the images you'll be watching most often. You can always show material in narrower or wider formats, too. As long as the resolution is one that the projector can accept, which is something you can check in the projector specs, it will either scale the image to fit in the projector's native aspect ratio, or keep the image's aspect ratio to avoid distortion and add letterbox bars (black bars to the sides for narrower formats, or black bars above and below for wider formats). Almost all projectors today include aspect-ratio settings to let you choose which approach to use.

Note that the ability to show images with different aspect ratios than the projector's native resolution gives you some flexibility in matching the projector to the images you plan to watch. For example, you can use a native WUXGA projector, with its 16:10 aspect ratio, to watch movies or TV with a 16:9 aspect ratio. Keep in mind that if you set up a 16:10 projector to fill your 16:9 screen with the picture, you'll need a sufficiently wide black border at the edges to keep the letterbox bars from showing as brighter areas surrounding the screen.
