Abstract

A display device for preventing degradation and a compensation method thereof are disclosed. A display device according to the present invention comprises: a display panel of a plurality of sub-pixels; a degradation compensation unit configured to compensate for degradation of the degraded sub-pixels based on a sensing voltage input from the display panel, and to dim the plurality of sub-pixels in response to the compensation; and a memory configured to store a lookup table, the lookup table including a gain, a degradation compensation time, and a target luminance.

Description

technical field [0001] The present invention relates to a display device for preventing or at least partially reducing degradation and a compensation method therefor. Background technique [0002] With the development of multimedia, the importance of flat panel displays is increasing day by day. Thus, flat panel display devices such as liquid crystal display devices, plasma display devices, and organic light emitting display devices have been commercialized. Among these flat panel display devices, organic light emitting display devices are currently widely used due to their high-speed response speed, high brightness, and excellent viewing angle. [0003] However, the luminance characteristics of the organic light emitting display panel may be deteriorated due to deterioration of the organic light emitting device after a certain period of time. When the driving time is increased, the deterioration rate of the organic light emitting diode is accelerated, and the luminance ch...
