摘要： The present invention provides a method to reduce the power consumption. The method comprises these steps. First, the RGB gray levels of a pixel are decided. Then, the RGB gray level values are transformed to XYZ tristimulus values. The XYZ tristimulus values are transformed to L*a*b* values. Next, the L*′a*′b*′ values are determined based on an acceptable color difference range. The color difference between the L*′a*′b*′ and the L*a*b* is in the color difference range. Finally, the L*′a*′b*′ values are transformed to X′Y′Z′ values and the X′Y′Z′ values are transformed to R′G′B′ gray level values.

摘要： A light emitting diode (OLED) display and pixel driving method thereof are disclosed. Each storage capacitor is discharged via the driving TFT and OLED until conductive current of each OLED is almost zero so as to record a sum of a voltage drop across each OLED under a specific condition and the threshold voltage of the driving TFT. By using the sum of the voltage drop across each OLED and the threshold voltage of the corresponding TFT in the subsequent OLED driving process, the luminance reduction issue caused by TFT threshold-voltage shift and OLED material decay can be solved.
