The continuous color compensation technology is called SCR (Sequential Color Recapture) in English, which is one of the DLP technologies. If you need to understand the definition of continuous color compensation technology, we first familiarize yourself with several DLP color technologies, by understanding the difference between DLP other color technologies and continuous color compensation technology. Perhaps there will be a deeper understanding of continuous color compensation technology.
1. The basic principle of continuous color compensation technology
The basic principle of continuous color compensation technology is similar to the above color wheel technology, the difference is that the surface of the color wheel adopts Archimedean principle spiral optical coating, and the light collecting column (light channel) uses a special Gain technology can compensate for part of the reflected light, so that the system brightness is greatly improved (about 40%). However, the processing technology of the color wheel is relatively complicated. Currently, only a few projector manufacturers adopt it in products. From the perspective of technological development, this technology is very exciting.
2. the difference between continuous color compensation technology and other DLP color wheel technology
Continuous color compensation technology is one of several commonly used DLP color wheel technology, so what is the difference between it and other DLP technologies?
1. Three-segment color wheel RGB
The three-segment color wheel RGB is composed of three segments of red R, green G, and blue B. The products of different manufacturers have different designs for the opening angles of red, green, and blue. Generally speaking, the opening angle of red is larger , Which can make up for the lack of red in the image. The prerequisite for using this color wheel technology is that the projector's optical machine part has relatively sufficient brightness, otherwise it may cause image brightness problems. At the same time, the color reproduction using the three-segment color wheel technology is relatively good.
2. Four-segment color wheel RGBW
The four-segment color wheel RGBW consists of four segments: red R, green G, blue B, and white W. The purpose of adding the white segment color is mainly to further increase the brightness of the projector. Generally, it can be increased by about 20% compared with the three-segment color wheel. But at the same time, this color wheel technology will also cause the problem of insufficient color reproduction of the projector, distorting the image color and reducing the image quality. In addition, in the design, the pulse signal can be synchronously locked in the W segment, and the pulse width corresponds to the width of the W segment, which can reduce the flicker of the picture to a certain extent. This technology is mainly used in conference rooms and teaching projectors.
3. Six-segment color wheel RGBRGB
Since DLP technology is more and more widely used in home theater projectors and rear projection TVs with huge market potential, people have put forward a higher effect on the color of DLP and the effect of playing continuous dynamic video pictures. Requirements.
The six-segment color wheel is a color wheel composed of six RGB RGB colors. With the corresponding increase in the speed of the color wheel (180HZ) and more pictures processed per unit time, this design effectively reduces moving images and rainbows on the edges. Effect, the dynamic effect of the video is better, the color of the image is richer and more gorgeous. However, due to the more six-segment segmentation and more light loss when the light beam passes through each color segment, the brightness of the projector is often lower. Therefore, a few projector manufacturers have begun to design and adopt the 7-segment RGBRGBW technology To increase the brightness of the projector and reduce the flicker of the picture. This technology is mainly used for applications that require high household consumption and video.
