Questions about Display Device Technology

What are the key components of a display device?

A display device typically includes a display panel, data driver, gate driver, light-emission signal generator, and a controller to operate the device efficiently.

How does the duty ratio of the light-emission signal impact image quality?

The duty ratio of the light-emission signal being smaller than the parking voltage helps reduce mura and improve the uniformity of the display panel, resulting in enhanced image quality.


Original Abstract Submitted

A display device includes a display panel including a plurality of pixels connected to a data line and a gate line; a data driver configured to apply a data voltage to the data line for an active period and to apply a parking voltage to the data line for a blank period for which the data voltage is not applied; a gate driver for applying a scan signal to the gate line; a light-emission signal generator for applying a light-emission signal to the plurality of pixels; and a controller configured to operate the display device based on a plurality of bands, wherein the plurality of bands have different highest target luminance levels based on operating environments of the display device, wherein in at least one of the plurality of bands, a duty ratio of the light-emission signal is smaller than a duty ratio of the parking voltage. Thus, parking voltage mura is reduced and uniformity of the display panel is improved to improve image quality.
