Abstract

A display apparatus and a method of operating the display apparatus are provided. The display device includes a display panel, a controller, and a data driver. The display panel includes a plurality of pixels. The controller detects a logo region including a logo in the image data, determines a correction gain based on a first average grayscale level of the logo region and a second average grayscale level of a peripheral region adjacent to the logo region, and generates corrected image data by correcting the image data based on the correction gain. The data driver provides a data signal to the plurality of pixels based on the corrected image data.

Description

technical field [0001] One or more embodiments described herein relate to a display device and a method of operating the same. Background technique [0002] When a display device is operated over time, the pixels of the display device may become degraded. The degradation experienced by the pixels can seriously degrade the display quality, especially for pixels used to display logos for long periods of time. These effects are exacerbated when the logo includes high gray scale images. If extended, an afterimage will appear in the pixel area where the logo is displayed. Contents of the invention [0003] One or more embodiments described herein provide a display device that can reduce degradation and after-image effects, including but not limited to degradation and after-image effects in a logo area. [0004] One or more embodiments described herein can reduce or prevent grayscale banding in the logo area and peripheral areas. [0005] One or more embodiments described he...
