Problems solved by technology

[0004] In such a display device having a single-side drive type, RC load unevenness occurs at pixels of the display panel, and the timing at which the scan signal and the data signal are supplied to each of the pixels is not synchronized, resulting in data charge rate deviation , which degrades the display quality

Abstract

A display device is provided. The display device includes: a display panel including scan lines, first signal lines connected to scan lines in a first pixel block, second signal lines connected to scan lines in a second pixel block, and third signal lines connected to scan lines in a third pixel block; a first scan driver supplying a first output signal to the first signal line based on the first sub-clock signal; a second scan driver supplying a second output signal to a second signal line based on a second sub-clock signal; a third scan driver supplying a third output signal to a third signal line based on a third sub-clock signal; and a timing controller. The change in the pulse width of the first output signal to the change in the pulse width of the third output signal is different in one frame period.

Description

[0001] This patent application claims priority from Korean Patent Application No. 10-2020-0119405 filed with the Korean Intellectual Property Office on September 16, 2020, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to an electronic device, and more particularly, to a display device. Background technique [0003] A flat panel display (FPD) is an electronic viewing technology for enabling people to see content (eg, still images or moving images). FPDs are lighter, thinner and use less power than conventional cathode ray tube (CRT) displays. FPDs typically include a display panel with a plurality of pixels, a data driver for supplying data voltages, and a scan driver for supplying scan signals to rows of pixels that determine whether a given one of the pixels will receive one of the data voltages Voltage. As an example, a scan driver is provided at one side of the display panel, and a da...
