Abstract
An organic light emitting diode (OLED) display device is provided. The OLED display device includes a display configured to display a video and a controller configured to control the display, wherein the controller senses a fixed region in the video, obtains RGB data of the sensed fixed region, and reduces a saturation of the fixed region, based on the RGB data.
Claims14
An organic light emitting diode (OLED) display device comprising:
- a display configured to display a video;
- and
- a controller configured to:
- sense a fixed region in the displayed video, wherein the fixed region is a region including pixels where a variation of a pixel value for a certain time is less than or equal to a reference value;
- obtain RGB data of the fixed region;
- calculate saturation information of the fixed region based on the obtained RGB data of the fixed region;
- reduce saturation of the fixed region when the saturation information is greater than or equal to a predetermined reference value;
- and
- maintain the saturation of the fixed region when the saturation information is less than the predetermined reference value.
