Patent ID: 8537079

Claim:
A method for power control of an organic light-emitting diode (OLED) panel, comprising: estimating a voltage value according to an image data of an image, the voltage value indicative of a minimal required voltage allowing the OLED panel to display the image; estimating a first current value according to a plurality of luminance values converted from the image data, the first current value indicative of a load current flowing through the OLED panel associated with the image; estimating a second current value according to the plurality of luminance values converted from the image data, the second current value indicative of a maximal current flowing through one of a plurality of OLED elements of the OLED panel associated with the image; estimating a first voltage value according to the estimated first current value, the first voltage value indicative of a voltage drop of the OLED panel associated with the image; estimating a second voltage value according to the estimated second current value, the second voltage value indicative of a maximal display voltage of the OLED panel associated with the image; determining the voltage value indicative of the minimal required voltage according to a combination of the estimated first voltage value and the estimated second voltage value; and controlling a voltage generator to adjust a booster voltage provided to the OLED panel according to the voltage value indicative of the minimal required voltage.
