With the rapid development of the display industry, mobile phone screens have been upgraded from 1K in the past to 2K, 2.5K, and even 4K. Resolutions above 4K have been widely adopted in the TV screen and gaming screen industries. Screen types are becoming increasingly diversified, including LCD, OLED, Mini LED, Micro LED, etc., which puts forward extremely high requirements for screen detection accuracy of 1~5 microns. In addition to the improvement of detection accuracy, the screen production line also puts forward new requirements for detection and monitoring real-time, and cameras below 100 million pixels cannot meet the inspection needs. Therefore, in order to solve the problems currently encountered by screen manufacturers, cameras with more than 100 million pixels have become a necessary condition for screen detection.
Lingyunguang's self-developed 150 million pixel large-area array camera is equipped with a Global chip and a leading global shutter, which can easily shoot sports scenes. Through 8-, 10-, 12-bit high-bandwidth transmission and a variety of data interfaces CXP6, CameraLink, the maximum resolution of 15fps is achieved, effectively improving the detection efficiency and being born for screen detection.
100% match 16:9TV screen
The camera's excellent aspect ratio of 16.3K*9.2K perfectly matches the 16:9 TV screen. Achieve a 4K screen detection ratio of 4~5, and can detect 8K screens with a single camera, easily coping with the detection needs of high-resolution 4K/8K/16K screens.
Effectively improve the detection rate of shallow mura defects
The detection of dark screen mura improves the signal-to-noise ratio by 12dB, and can detect mura below 5dB
The characteristic algorithm of Lingyunguang can effectively reduce the random noise introduced by the device and improve the signal-to-noise ratio of the image, thereby improving the detection effect of shallow Mura defects.
The 150 million pixel large area scan camera is a high-resolution, high-speed product created for the needs of screens, semiconductors, PCBs and other industries. The product won the 2022 Machine Vision TOP10 Innovation Award, demonstrating its leading position and superior performance in the industry.
