Abstract

A pixel compensation module according to one embodiment of the present disclosure detects a degraded region with reference to degradation data corresponding to each of pixels included in a display panel, determines a first compensation gain so as to decrease final compensation data of pixels included in the degraded region, and determines a second compensation gain so as to increase final compensation data of pixels included in an adjacent degraded region to correct compensation data of the pixels.

Description

technical field [0001] The present disclosure relates to a display device and modules and methods for compensating pixels of the display device. Background technique [0002] As an alternative to conventional cathode ray tubes, flat panel displays include liquid crystal displays, field emission displays, plasma display panels, organic light emitting diode (OLED) displays, and the like. [0003] Among these displays, OLEDs used in OLED displays have high luminance and low operating voltage characteristics. Because an OLED display is self-illuminating, it has a high contrast ratio. In addition, it is easy to realize ultra-thin displays using OLED displays. In addition, OLEDs have a response time of several microseconds (μs) and thus are suitable for presenting moving images. Furthermore, it has no limitation on the viewing angle and can be stably driven even at low temperatures. [0004] Pixels each including an OLED are arranged in a matrix in the OLED display. A data vo...
