Home projector LCD technology and the DLP technology

LCD and DLP projectors are the current mainstream technology, which technology is better? That there is no standard answer, it depends entirely on the applications. Techniques have strengths and key for consumers to understand their needs, understanding the characteristics of LCD and DLP each, on-demand options.

LCD projector is the LCD imaging device, when the light through the LCD panel, each pixel according to image signals are turned on or off, so that some light through, and some were cut off. By adjusting the light to produce the image projected onto the screen. The current mainstream LCD projectors have been used EPSON (Epson) 3LCD technology, which uses three LCD panels as imaging devices, optical system through the spectroscope the light was separated into red, green, and blue, individually for each a color brightness and contrast control, the performance of this color is very important. As the current 3LCD technology has been very mature, three-color light to reach the screen is almost the same time, so the control circuit in the high quality 3LCD projector, the projection is very good, bright true color reproduction, rich layers and color saturation.

The disadvantage of early LCD projectors, and now one by one to improve. Such as LCD projector prone to the grid phenomenon, with the EPSON has launched the first 5th generation high-temperature polysilicon panels and projectors to improve the resolution has been hard to detect and use the 5th generation high-temperature polysilicon panels can greatly improve the projector's resolution, to 1920 × 1080, support for 1080p high-definition mode really. Moreover, the light efficiency and contrast are greatly improved, with aperture-linked technology; 3LCD technology has been achieved up to 6000:1 contrast ratio, which is of great significance for video playback. As a whole, the best color performance to 3LCD projection technology for motion video playback, ideal for home theater applications.

DLP projector LCD projector for it is a rising star. It works completely different from the LCD projector; the light source of the light emitted by high-speed rotating color wheel produces red, green, and blue, followed by alternate exposure to the DMD (Digital Micromere Device, DMD) of the surface. DMD micro mirror surface according to their corresponding pixels in the light of the availability of such colors and off two positions in the high-speed switching, and finally, after reflection by the mirror, projected onto the projection screen to form images. As a way of using reflection imaging, contrast can be very high, very good uniformity. Because there is no convergence problems, especially in the projection in the text show some small font text or drawings shows the best. Well suited to text and form-based business or education market.
DLP projector as the main color is determined to rely on the color wheel; color processing speed is low, poor color reproduction, but also the rainbow effect, the overall color performance to be inferior to 3LCD technology. As technology improved, the current color wheel has changed from the original RGB to RGBW three-stage development of four sections, on the home that require high color DLP projector or used RGBRGB Six-color wheel, color processing speed increases, substantially reducing Little of the rainbow effect. But from a practical effect, most DLP products still lack the kind of real ideal brilliant colors.

Overall, in the current high-end home projector market, high-end DLP products with ultra-high contrast, good color enhancement technology to win the favor of some users; in the same price on the 3LCD products favorably in all respects, Even more unique to show the film "film sense" screen, they are points and weak points. In the end home mirco projector market, 3LCD color performance with cost advantage and win most of the users concerned.
