Description:

Color and luminance of OLED panel may shift under different ambient temperatures. To address this, raw data from touch sensors can be used to obtain local temperature information. By using this data, the proposed compensation method can be employed to solve the effects of temperature-induced color and luminance shifts. After compensation, OLED panels can provide a more stable and reliable visual experience in diverse ambient temperatures.
