Abstract
An organic light-emitting diode display device include a display panel, and a processor configured to acquire average brightness of an image frame input to the display panel, determine a luminance maintaining region corresponding to a range, to which the acquired average brightness belongs, in an entire region of a screen of the display panel, and perform a convex power control (CPC) algorithm according to the determined luminance maintaining region.
Claims14
An organic light-emitting diode (OLED) display device comprising:
- a display panel;
- and
- a processor configured to:
- obtain an average brightness of an image frame input to the display panel, wherein the average brightness is within a range,
- determine whether a luminance maintaining region is within the range, wherein the luminance maintaining region corresponds to an entire region of the display panel, and
- perform a convex power control (CPC) according to a determination that the luminance maintaining region is within the range, wherein the CPC reduces power consumption of the OLED display device by reducing a luminance of an outer region of the display panel.
