Display panel and display device

Abstract

An embodiment of the invention discloses a display panel and a display device. The display panel comprises a liquid crystal light control panel and a liquid crystal display panel which are arranged ina laminated mode in the light emitting direction, wherein the liquid crystal light control panel comprises a plurality of light control sub-pixels, and each light control sub-pixel has a first opening area; the liquid crystal display panel comprises a plurality of display sub-pixels, and each display sub-pixel has a second opening area; the first opening area is smaller than the second opening area. By the adoption of the display panel and the display device, the display panel comprises the liquid crystal display panel and the liquid crystal light control panel, light emitted by a backlight source is adjusted through the liquid crystal light control panel, local backlight adjustment of the pixel level is achieved, and the display contrast of the liquid crystal display panel is improved; furthermore, the opening area of the sub-pixels in the liquid crystal light control panel is smaller than that of the sub-pixels in the liquid crystal display panel, so that the adjustment precision oflocal backlight is further improved, and the display contrast of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of good picture quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and has been widely used in tablet computers, TVs, mobile phones and Electronic products such as vehicle display areas. [0003] With the continuous development of display technology, in order to reduce power consumption and improve the contrast of the display panel, the liquid crystal display introduces a local backlight adjustment (Local Dimming) technology. Local backlight adjustment technology is to adjust the brightness of each area of ​​the backlight according to the image. However, whether it is side-type local dimming or direct-type local dimming, due to the problem of the LED light p...

Problems solved by technology

However, whether it is side-type local dimming or direct-type local dimming, due to the problem of the LED light pitch pitch, it is impossible to achieve finer image control and high contrast

In the past two years, mini-LED has developed rapidly and can be used as a direct-lit backlight. However, the yield rate and production cost are high, and mass production cannot be realized for the time being.
