Liquid crystal display panel and display device thereof

Abstract

An embodiment of the invention provides a liquid crystal display panel and a display device thereof and relates to the technical field of display. Color mixing degree of high-brightness subpixels andadjacent subpixels can be lowered, so that display color offset is improved. The liquid crystal display panel comprises first metal signal lines extending along a second direction, and each first metal signal line is a touch signal line and / or a nominal touch signal line; in a first direction, the first metal signal lines are adjacent to the high-brightness subpixels and color subpixels; each first metal signal line comprises a widening portion between the corresponding high-brightness subpixel and the corresponding color subpixel which are adjacent and further comprises a non-widening portionbetween two adjacent color subpixels, and width of each widening portion in the first direction is greater than that of the corresponding non-widening portion in the first direction.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a display device thereof. Background technique [0002] At present, the resolution and brightness of mobile phones, tablets and TVs are getting higher and higher, which not only allows us to have a clearer vision, but also improves the brightness and is conducive to the use of outdoor strong light, but the improvement of resolution and brightness indicators also affects the function of the panel. The power consumption has brought severe challenges. The traditional RGB arrangement panel can no longer meet the demand. Therefore, a bright sub-pixel (such as a white sub-pixel) is added to the original red, green and blue sub-pixels. The added bright sub-pixel white sub-pixel makes The brightness of the panel is increased by 60%, the power consumption is lower, and the text effect is sharper, and the light transmittance of the screen is improved.

[0002] At present, the resolution and brightness of mobile phones, tablets and TVs are getting higher and higher, which not only allows us to have a clearer vision, but also improves the brightness and is conducive to the use of outdoor strong light, but the improvement of resolution and brightness indicators also affects the function of the panel. The power consumption has brought severe challenges. The traditional RGB arrangement panel can no longer meet the demand. Therefore, a bright sub-pixel (such as a white sub-pixel) is added to the original red, green and blue sub-pixels. The added bright sub-pixel white sub-pixel makes The brightness of the panel is increased by 60%, the power consumption is lower, and the text effect is sharper, and the light transmittance of the screen is improved.

Compared with the traditional RGB array panel, the RGBW panel with high-brightness sub-pixels can greatly improve the penetration rate, but it also brings new problems. The high-brightness sub-pixel has a high penetration rate, which causes serious color mixing between the high-brightness sub-pixel and adjacent sub-pixels , resulting in a color shift in the display
