With applications led display more widespread, the use of the occasion has become increasingly complex, past the traditional single PC control led display can not meet the needs of users, while Daktronics company, Lighthouse companies have launched led display dedicated image processor to improve display led display.

Depending Jazz Asahi Optical to you on the next image processor dedicated led display four functions:

First, image processing technology

For different occasions, using different image processing technology to display images to be displayed pretreatment to improve the display effect of the display.

For example: As the fast-moving images caused by incoherent questions, can be moving image processing technology to ensure the smooth movement and display the best image; diagonal compensation check the video image of a diagonal pattern, so that the edge of the image It becomes smooth. Image sharpening technology highlights the edge of the image, so that the display is more clear and smooth. xcr5128-10pq100c

Second, the video signal conversion function

It supports VGA, SVGA, XGA format digital signal or an analog signal into a led display dedicated video signal format. Image Effects Daktronics company DV-Link image processor enhancements, the ability to PAL signal into an image signal 50 images per second screen, and the image signal of the NTSC signal into a 60 frames per second. After improving the picture playback speed so fast motion on the screen becomes coherent.

Third, adjustable GAMMA correction function

Gamma correction can improve the image of dark and bright areas, contrast transition or eliminate blur. Gamma correction realizes the image brightness adjustment, can enhance the image of the dark and light areas of the effect on the led display. 2SD466

Fourth, the color space conversion function

Since led display color space color space than the existing TV signal is much larger, and therefore, if the direct use of RGB three-color television video signal to control led tricolor luminescence display, will produce color deviation, so led displays color image and the original image is a clear distortion, seriously affecting the display. Image processor NTSC and PAL color values ​​are converted to color values ​​led, thus ensuring perfect video signal reproduction.
