According to information from the State Intellectual Property Office on July 28, 2025, Sun Microelectronics (Suzhou) Co., Ltd. applied for a patent titled "A Color Matrix-Based MicroLED Display Demura Preprocessing Method and System", with the publication number CN120375755A, and the application date is May 2025.
The patent summary shows that the present invention proposes a color matrix-based MicroLED display Demura preprocessing method and system. Based on the imaging colorimeter, the brightness and chromaticity distribution data of the MicroLED display panel are obtained; based on these data, accurate calculations are performed through the compensation algorithm to obtainCompensation value for each pixel; these compensation values are applied to the display panel drive circuit to achieve accurate compensation for the Mura phenomenon. The present invention determines the optimal compensation target value by automatically analyzing the brightness and chromaticity of Mura data. Through the support of Mura data and the compensation algorithm, it can achieve precise compensation at the pixel level. The system can monitor the input data of the display panel in real time and adjust the compensation value in real time. It has good scalability and the system can support MicroLED display panels of different sizes and resolutions. The system is mainly composed of data acquisition and processing module and compensation value preprocessing calculation module.
