Patent ID: 8797368

Claim:
An organic light-emitting diode (OLED) display device comprising: an image analyzer for obtaining an emission ratio and a saturation of an input source image, the emission ratio indicating light-emitted degrees of pixels constituting the input source image; an emission ratio adjuster for adjusting the emission ratio according to the saturation; a brightness adjuster for adjusting the brightness of the input source image according to the adjusted emission ratio; a data driver for establishing a data voltage of a data signal corresponding to the input source image based on the adjusted original brightness; and a pixel unit comprising an organic light-emitting diode (OLED), the pixel unit being configured to establish a driving current according to the data voltage and to receive a scan signal, an emission control signal, and the data signal in order to allow the OLED to emit light, wherein the emission ratio adjuster is configured to increase the emission ratio when the saturation of the input source image is higher than a reference value, and wherein the brightness adjuster is configured to increase a brightness reduction ratio when the emission ratio of the input source image is higher and to decrease the brightness reduction ratio when the emission ratio is lower.
