Liquid crystal display, driving method of liquid crystal display and display device of liquid crystal display

Abstract

The invention discloses a liquid crystal display, a driving method of the liquid crystal display and a display device of the liquid crystal display. A color resistance arrangement method of all sub pixel units in adjacent-row pixel units in at least one group of two adjacent rows of pixel units in the liquid crystal display is changed to enable the color resistance colors of two adjacent-row sub pixel units belonging to two different pixel units to be identical. Furthermore, the position of a data line connected with the sub pixel unit with the same color as the color resistance color is changed, the data line is arranged far away from the outer sides of the two sub pixel units with the same color resistance color, the color mixture phenomenon is avoided, and meanwhile a black array arranged in a gap between the two sub pixel units is removed. Namely, the opening portions, corresponding to the two sub pixel units, in an image of the black array are combined into one. The opening rate of all sub pixel units can be improved by reducing the image portion of the black array. Thus, the light transmittance of all sub pixel units is improved. Furthermore, the display luminance of the liquid crystal display is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a liquid crystal display screen, a driving method thereof and a display device. Background technique [0002] The liquid crystal display screen is mainly composed of an array substrate, an opposite substrate, and liquid crystal molecules located between the two substrates; a plurality of pixel units arranged in a matrix are arranged in the liquid crystal display screen, and each pixel unit is composed of four color resistors. It is composed of sub-pixel units with different colors, and the four color resistance colors are generally RGBW, RGBY or RGBC. Specifically, gate lines, data lines, thin film transistors (TFTs) and pixel electrodes are arranged on the array substrate; black matrix, color resin (generally RGBW, RGBY or RGBC) and common electrodes are arranged on the opposite substrate. When a high-potential scanning signal is input to the gate line, the TFT co...

Problems solved by technology

[0003] At present, in order to obtain a wide color gamut and better quality display colors, the thickness of the color resin in the liquid crystal display is generally increased. However, a thicker color resin will reduce the light transmittance of each sub-pixel unit, thus affecting the liquid crystal display. display brightness

Although the method of increasing the brightness of the LCD backlight can ensure the display brightness of the LCD, the high-brightness backlight will increase the power consumption of the entire LCD module.

In addition, it is also possible to increase the aperture ratio of each sub-pixel unit to ensure the light transmittance of each sub-pixel unit. However, due to the limitation of the precision of the liquid crystal display cell process, it is necessary to ensure that the black matrix has a thickness greater than that of the sub-pixel unit. Light leakage area and process precision width, which is not conducive to improving the aperture ratio of each sub-pixel unit

Moreover, with the development of high-resolution liquid crystal display devices, the aperture ratio will also be further reduced.
