A method of aging a display device includes: inputting a display device including a plurality of pixels into an aging chamber, reaching a preset condition of the display device, sensing each of the plurality of pixels, compensating each of the plurality of pixels, and aging the display device.

Method of aging a display device

A liquid crystal display according to an exemplary embodiment of the present disclosure includes: a first substrate where a pixel electrode is formed; a second substrate facing the first substrate; a liquid crystal layer provided between the first substrate and the second substrate; and a driving device connected with the first substrate, wherein the first substrate includes a pixel area where pixels emit light, and a load storage area provided between the pixel area and the driving device and constantly maintaining a load applied to the pixels in the pixel area.

Liquid crystal display

In a method of driving a display panel, a gate signal is outputted to the display panel based on a first control signal. A gamma-corrected analog voltage is generated. A pre-charge compensating analog voltage is generated. A data voltage waveform is generated to include the generated gamma-corrected analog voltage and the generated pre-charge compensating analog voltage during one horizontal period of the display panel. The display panel has a pixel structure in which a data line is alternately connected to first and second subpixel columns adjacent to each other. The pre-charge compensating voltage has a level different from that of the gamma-corrected analog voltage where the latter represents a grayscale level represented by a received digital data signal. According to the method, display defects due to a difference of pre-charging levels used during plural horizontal periods may be decreased so that display quality of the display panel may be improved.
