Abstract

The invention discloses a liquid crystal display device comprising: a base plate, at least one thin-film transistor, a protection layer, a lower common electrode layer, a pixel electrode layer and a liquid crystal layer. The thin-film transistor which consists of a grid electrode, a source electrode and a drain electrode is disposed on the base plate. The protection layer is positioned on the thin-film transistor and the base plate, and the lower common electrode layer which contains a lower common electrode is disposed on the protection layer. The pixel electrode layer which includes at least one pixel electrode is disposed above the lower common electrode layer, the pixel electrode is electrically connected to the drain electrode, and the liquid crystal layer is positioned on the pixel electrode layer. During image display, independent voltage sources provide lower common voltages separately for the liquid crystal display device, which can prevent the image exception caused by feed through voltage.

Description

technical field [0001] The present invention relates to a liquid crystal display device, a liquid crystal display device using HUA (HannStar Ultra-high Aperture) technology, in particular to a liquid crystal display device with a plurality of common electrodes having an independent voltage source. Background technique [0002] Liquid crystal display devices have the characteristics of light and thin appearance, low power consumption and no radiation pollution, and have been widely used in portable information products such as notebook calculators (notebooks) and personal digital assistants (personal digital assistants, PDAs). Cathode ray tube monitors that have gradually replaced conventional desktop computers. [0003] The driving of the known liquid crystal display device is to utilize the arrangement of pixel electrodes on the surface of the lower substrate, and the arrangement of shared electrodes on the surface of the upper substrate or the lower substrate, and by provi...
