Embodiment Construction

[0027] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In the existing pixel electrode structure, it includes a red sub-pixel electrode unit, a blue sub-pixel electrode unit, and a green sub-pixel electrode unit. Each of the three sub-pixel electrode units has a certain electrode width W (the electrode is strip-shaped, W is the width of each bar) and the slit width L between the electrodes, generally the electrode widths in the three sub-pixel electrode units are the same and the slit widths between the electrodes are also the same, and the electrodes in the three sub-pixel electrode units are all set to the same The tilt angle, which makes the transmittance of the red light pixel relatively increase during the deflection process of the liquid crystal from the normal...

Abstract

The invention relates to a pixel electrode structure, an array substrate with the pixel electrode structure and a display device with the pixel electrode structure and belongs to the technical field of display. According to the pixel electrode structure, in order to eliminate a color cast phenomenon which often takes place in display technologies under the drive mode of advanced super dimension switch (ADS), the ratio of the electrode size to the electrode spacing in a blue sub-pixel electrode unit is set to be larger than ratios of a red sub-pixel electrode unit and a green sub-pixel electrode unit, so that a gap design of a pixel electrode of a blue pixel is different from gap designs of a red pixel and a green pixel, namely a gap of the pixel electrode of the blue pixel is designed to be provided with high transmittance so as to prevent transmittance of the red pixel from being too large, the problem that the yellow color cast phenomenon taking place in a transmission area is caused due to the fact that anisotropism of a refractive index is increased in a middle tone is solved, and transflective light emitting diodes (LEDs) with good image qualities can be further manufactured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel electrode structure, an array substrate and a display device. Background technique [0002] At present, a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is a display device mainly used in display products. Since notebook computers, monitors, televisions and other products are mostly display devices mainly used indoors, most of them adopt transmissive TFT-LCD products. Advanced Super Dimension Switch (ADS) has the advantages of high resolution, high transmittance, low power consumption, wide viewing angle, high aperture ratio, low chromatic aberration, and no push Mura. It is widely used in various display products. Its core technology is: 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 to form a multi-dimension...
