Eliminate the difference Point-by-point correction is a technology to enhance the brightness uniformity and color fidelity of the LED electronic screen. By collecting the data of each pixel on the LED display, the correction coefficient matrix is given and then fed back to the display Control system to achieve the difference between the pixel drive, reducing the brightness and color differences.
Point-by-point correction is a technology to enhance the brightness uniformity and color fidelity of LED electronic screens. By collecting data from each pixel on the LED display, the correction coefficient matrix is given and then fed back to the display control system , To achieve the difference between the pixels driven, reducing the brightness and color differences. This technology can make different batches of stalls together, but also the screen shows pure and delicate, true color natural.
Depending on the application, the point-by-point calibration system is divided into two types:
1, a single LED box by point correction, in the production line by box correction, to ensure that the factory each box to achieve a high degree of uniformity;
2, the scene of large-screen point by point correction, in the LED full-color large screen display site to select the appropriate viewing location for field calibration to ensure that the display site in the field to achieve a high degree of uniformity.
