Elimination of differences Point by point correction is a technology used to improve the brightness uniformity and color fidelity LED electronic screen, through the LED display on each pixel data acquisition, correction coefficient matrix is given, and then fed back to the display Control system to achieve the pixel-driven difference, reducing the brightness and color differences.
Point-by-point correction is a technology used to improve the brightness uniformity and color fidelity LED electronic screen, through the LED display on each pixel data acquisition, correction coefficient matrix is given, and then fed back to the display control system , To achieve the pixel-driven difference, reduce the brightness and color differences. This technology allows different batches of tail splicing together, but also the picture shows the pure and delicate, the color is real.
First, depending on the application, point by point correction 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 of each box to achieve a high degree of uniformity;
2, On-site large-screen point-by-point correction, the full-color LED large-screen display at the scene to choose the appropriate site for on-site correction to ensure that the display site observation site to achieve a high degree of uniformity;
