Problems solved by technology

[0003] However, the temperature of the components of the display device (e.g., the controller and / or the power management circuit) may increase through such mura correcting operation
In addition, through this temperature increase, the display device may be damaged or not operate properly (e.g., fail to operate as desired)

Abstract

Disclosed are a display device, and a method of operating the display device. The display device includes a display panel including a plurality of pixels, a gate driver configured to provide gate signals to the plurality of pixels, a data driver configured to provide data signals to the plurality of pixels, a correction data memory configured to store mura correction data, and a controller configured to control the gate driver and the data driver. The controller includes a pattern detection block configured to detect a set pattern in input image data, and a mura correction block configured to perform a mura correction operation that corrects the input image data based on the mura correction data in response to the set pattern not being detected, and to not perform the mura correction operation in accordance with the set pattern being detected.

Description

technical field [0001] Exemplary embodiments of the inventive concept relate to a display device, and more particularly, to a display device selectively performing a mura correction operation and a method of operating the same. Background technique [0002] Even if a plurality of pixels included in a display device are manufactured through the same process, the plurality of pixels may have brightness different from each other and color coordinates different from each other due to process variation and the like. Therefore, luminance mura defects and / or color mura defects may occur in the display device. In order to reduce or eliminate luminance and / or color mura defects, and to improve the uniformity of luminance and / or color coordinates of the display device, an image displayed by the display device in a module state may be captured, and mura correction data may be generated based on the captured image , and the mura correction data can be stored in the display device. The...
