Abstract

A screen saver controller, a display apparatus, and a method of operating the display apparatus are provided. The screen saver controller includes: a load calculator for generating load data for each of a plurality of panel blocks included in a display panel based on input image data; a life calculator for generating life data for each of the plurality of panel blocks based on a deterioration stress value accumulated in the display panel; a first logic circuit to receive the load data and the life data, and to generate operational data based on the load data and the life data; and a second logic circuit to receive the input image data and the operation data, and to generate screen protection data based on the input image data and the operation data. When operating in a screensaver mode for performing a screensaver operation, the screensaver controller adjusts a brightness of the display panel based on the screensaver data.

Description

technical field [0001] Embodiments of the inventive concept relate to a display device. More particularly, embodiments of the inventive concept relate to a screen saver controller, a display device including the same, and a method of operating the display device including the same. Background technique [0002] A display device may include a display panel and a display panel driver. The display panel includes pixels. Image data input to the pixels causes the display of the image. The display panel may be connected to a display panel driver through gate lines and data lines. The display panel driver may include a gate driver supplying gate signals to the display panel through gate lines, a data driver supplying data voltages to the display panel through data lines, and a timing controller controlling the gate driver and the data driver. [0003] When a predetermined condition is satisfied, the display device may operate in a screen saver mode. When the display device ope...
