"LED large-screen flat panel display high-precision digital parameters of light-color acquisition technology research " , "led large-screen flat panel display gray control and brightness calibration correction control technology development and application of demonstration " , "led large-screen flat panel display high-quality image display The three topics of " support technology and inspection and evaluation technology research " are an important part of " research on key technologies for high-definition and high-uniformity full-color led display devices ." The following led display manufacturers will introduce the importance of these three topics for you one by one .

　　

Wherein, "Study of high-precision light color flat panel display technology parameters led large screen digital acquisition" proposed method accurately bright light color parameter processing parameter acquisition method line by line with a non-isolated bright, led the development of large-screen display The high-speed, high-precision, bright-color parameter adaptive acquisition system provides important support for the further development of the LED display brightness and color calibration control technology and related detection and evaluation technologies.

　　

In the “LED display large-screen flat panel display control and brightness and color correction control technology research and development and application demonstration ” , the research group adopted a mixed gray weight modulation method based on the time distribution of mixed weight, brightness and chroma coefficient separation correction technology, and solved led display bright and high precision gradation control of uniformity problem, has broken the "integrated triple play" packaging technology, and the annual output of 30,000 m2 built high led large screen display line, led to a large screen flat panel display industry level Upgrade provided technical support.

　　

"The study of high-quality image display support technology and detection evaluation technology for led large-screen flat panel displays " , the research group created an image uniformity evaluation model based on hvs , and established a large led brightness, color, bright color uniformity, viewing angle, display The led special integrated detection platform for grayscale and other indicators improves the display quality of high-end led large-screen displays from the image source .
