A method for controlling power of an active matrix organic light-emitting diode (AMOLED), comprising:
- calculating a frame data rate, which is a ratio of a light emitting pixel quantity representing a specific color in an image data to be displayed;
- determining a luminance reducing amount mapped to the frame data rate;
- and
- controlling and displaying an entire luminance of an image according to the luminance reducing amount.
A power control device of an AMOLED, comprising:
- a display unit for displaying image data and formed with the AMOLED;
- and
- a controller for:
- calculating, when displaying the image data, a frame data rate, which is a ratio of a light emitting pixel quantity representing a specific color in the image data;
- determining a luminance of the image data according to the frame data rate;
- and
- providing the luminance of the image data to the display unit.
