The invention discloses a liquid crystal pixel electrode structure, an array substrate and a display device, and relates to the field of display technology. The electrode structure includes: a first pixel electrode and a second pixel electrode, and a common electrode, the first pixel electrode and the second pixel electrode are arranged at intervals in sequence, and are located above the common electrode, and the first pixel electrode It is different from the driving voltage of the second pixel electrode, and forms an equal absolute value of voltage difference with the common electrode respectively. In the present invention, two kinds of pixel electrodes can generate an electric field with each other, and at the same time, these two electrodes can also generate an electric field with a common electrode respectively, and the combination of the two electric fields can reduce the demand for driving voltage and reduce energy consumption. In addition, the common electrode in the present invention adopts a slit electrode, so that the light transmittance is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal pixel electrode structure, an array substrate and a display device. Background technique [0002] In liquid crystal display technology, AD-SDS (ADvancedSuperDimensionSwitch, advanced ultra-dimensional field switching technology, referred to as ADS) mode gradually replaces TN (TwistedNematic) liquid crystal mode with the advantages of high transmittance, wide viewing angle, fast response speed and low power consumption. It has become one of the important technologies in the field of liquid crystal display. [0003] The display based on ADS mode forms a multi-dimensional electric field through the electric field generated by the edge of the slit electrode in the same plane and the electric field generated between the slit electrode layer and the plate electrode layer, so that all orientation liquid crystals between the slit electrodes and directly above the electr...
