Patent number: 12333985Abstract: This application discloses a compensation method for a pixel circuit and a display panel. The compensation method firstly obtains the nonlinear function of the pixel circuit, then converts the nonlinear function into a corresponding linear function, and then obtains the compensated first gate-source voltage difference according to the linear function and the second gate-source voltage difference. Since the nonlinear function requires more compensation data and has a larger error than the linear function, using the converted linear function for compensation can reduce the required storage resources and improve the accuracy of compensation.Type: GrantFiled: December 31, 2023Date of Patent: June 17, 2025Assignee: Shenzhen China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventor: Tao Bi
