Abstract

A display device is provided. The display device includes: a display panel including a plurality of pixels configured to receive pixel driving currents; a current sensor configured to measure an entire driving current diverged into the pixel driving currents; and a temperature sensor configured to measure an ambient temperature of the display panel, wherein the display panel includes a degradationcompensator configured to generate output grayscale values for the pixels based on the entire driving current, the ambient temperature, and input grayscale values for the pixels.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2019-0036255 filed with the Korean Intellectual Property Office on March 28, 2019, the entire contents of which are hereby incorporated by reference. technical field [0002] Aspects of some example embodiments of the present invention relate to a display device and a driving method thereof. Background technique [0003] With the development of information technology, the importance of a display device as a connection medium between a user and information has become remarkable. Accordingly, display devices such as liquid crystal display devices, organic light emitting diode display devices, and plasma display devices have been increasingly used. [0004] Each pixel of an organic light emitting diode display may include at least one organic light emitting diode. With the increase of usage time, the organic light emitting diode will be degraded, and more driving current is required to di...
