In order to achieve the perfect effect of the full AMOLED display, the research on the brightness compensation technology of UDC(Under‐Display Camera) panel is proposed. Linear interpolation is performed through attenuation at different temperatures to obtain temperature gain compensation values, which compensate for attenuation problems of the UDC area at different temperatures. Nonlinear regression model is established and predicted through attenuation at different DBV(Display Brightness Value) to obtain DBV gain compensation values, which compensate for attenuation problems of the UDC area at different DBV. Data statistics and algorithm compensation are performed by DDIC(Display Driver Integrated Circuit) to optimize and solve the color deviation of UDC panel, and the ultimate effect of the full screen is achieved.
