The colored light that the mirrors reflect is then combined and passes through the projection lens to form an image. Texas Instruments has created a new system called BrilliantColor, which uses system level enhancements to give truer, more vibrant colors.
Customers can expand the color scope beyond red, green and blue to add yellow, white, magenta and cyan, for greater color accuracy. Once the DMD has created a picture out of the light and the color wheel has added color, the light passes through a lens. The lens projects the image onto the screen. Sign up for our Newsletter!

Each mirror creates one pixel. The total number of mirrors corresponds to screen resolution. For example, a 2K DLP projector has about 2. A 4K device about 8. The greater the resolution, the better the image quality. In turn, they deliver 8. This is not the same as the ability to reproduce actual 4K images. Contrast ratio compares the darkest and lightest values a projector can produce.
The higher the contrast ratio, the better the picture quality. DLP projector contrast ratios range from to , Contrast ratio is an important spec for home theater projectors and high-end use. For home theater applications, look for a contrast ratio in the range of 10, to , Bigger is better. For large venues, like auditoriums, go for the best: , A high contrast ratio is less critical in classrooms and conference rooms, as the benefits are most noticeable in highly light-controlled, pitch-black rooms.
For business and classrooms, look for contrast ratios in the range of 4, — 30, Projector brightness is measured by how much light the projector can output, called lumens. The more lumens, the brighter the projector. Higher brightness also means a higher cost. Ideal use: home theater. DLP projectors in this range produce a crisp, clear image, even on larger screens.
This enables ease of viewing with larger audience sizes. Select DLP projectors have added features. These enhancing characteristics build upon key specs noted above. Home theater enthusiasts are among those who seek the ultimate in color performance.
Cinematic color projectors offer outstanding home theater experiences by combining the following features to deliver a stunning, cinematic experience. Certification with Rec. Standard DLP projectors use 3-segment color wheels. The result: vivid images with smoother color gradients.
ISF-certified projectors have day and night modes that deliver optimized color in both bright and dark environments. If needed, ISF-certified technicians can provide on-site tuning for customized image calibration. The main benefit of choosing a projector over a TV comes from the ability to create a much larger screen image. Look for quality of life features that help you adjust that image to perfection.
Lens shift enables DLP projectors to adjust projected images without having to physically move the projector. Projectors with vertical lens shift deliver added flexibility for challenging professional installations. For home users, lens shift enables easier optimization of image placement. Look for horizontal and vertical HV keystoning and 4-corner adjustment features to eliminate crooked and distorted images. Doing so creates perfectly proportioned pictures.
This lets users magnify images without moving the projector. Optical zoom allows for placement further from the screen without reducing image quality. Thank you for shopping with us. Due to global chip shortages and supply chain issues affecting our industry, we strongly encourage you to start your holiday season shopping early this year. These issues are causing significant delays for many products, and consumer demand during the holiday season will likely make the situation worse.
Please note that items ship on a first come, first serve basis — reserve your desired items today to ensure you have them before the holiday rush. Most cinema theaters use 3 chip DLP projectors to show movies.
Due to the Persistence of Vision of our eyes, our brains assume it is a complete picture. Some people have problems watching films or videos on a DLP projector. The animated image here shows how the DLP color wheel works. When white light passes through this colored glass, for example through Red glass, Green and Blue light in the white light is blocked and only Red light is allowed to pass through.
Similarly at the Green section of the color wheel, only Green light passes through and in the Blue section only Blue light passes through. These illusionary flashes of bright colors are called the Rainbow Effect. The cause of the Rainbow Effect is because the single DLP projector shows the Red, Green and Blue portions of every frame in the video image separately and in quick succession. Because our brains processes these rapid sequences of separate RGB pictures as one, due to our persistence of vision, some people experience the Rainbow Effect which confuses them.
Single-chip DLP projectors are the most common type of home projectors and produce sharp images. Three chip DLP projectors are very expensive and mainly used in Cinema theaters.
