Embodiment Construction

[0020] It should be pointed out that there are two types of liquid crystal display devices: direct-type and side-type. Direct-type liquid crystal display devices such as figure 1 As shown, the blue backlight light source 11 is arranged directly below the display screen, and the emission direction of the excitation light faces the direction of the screen, while in the side-entry type liquid crystal display device, the blue backlight light source 11 is arranged on one side, and the emission direction of the excitation light is Parallel to the screen, and the excitation light is processed by other components so that the excitation light hits the direction of the screen. However, no matter what type of liquid crystal display device, its working principle is to excite the quantum dot material in the filter panel to emit light through excitation light, and the pixel unit of each color in the filter panel is connected to the pixels of the other two colors. The cells are adjacent to e...

Abstract

A quantum dot liquid crystal panel and a liquid crystal display device. The liquid crystal display device comprises: a light source mechanism (21), and a liquid crystal layer (22) and a color conversion layer (23), wherein the liquid crystal layer (22) is provided with a plurality of interval sections, each of the plurality of interval sections corresponds to each pixel unit in the color conversion layer (23) and is externally provided with a switch, and in the color conversion layer (23), adjacent to both ends of a green pixel unit (232) is a red pixel unit (231); adjacent to both ends of a blue pixel unit (233) is the red pixel unit (231); and adjacent to one end of the red pixel unit (231) is a blue pixel unit (233), and adjacent to the other end thereof is the green pixel unit (232). In comparison with the related art, in the solution, even if an exit angle of a backlight source is large, color crosstalk will not occur when pixel units adjacent to a target pixel unit are irradiated, such that the color of an image displayed by a liquid crystal display device is corrected, and the user experience of a user can thus be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical technologies, and in particular, to a liquid crystal display device. Background technique [0002] As a display device with low radiation, low energy consumption, and light and thin volume, liquid crystal display devices have been widely used. At present, not only liquid crystal displays are widely used in computer monitors, but also almost all TV sets that provide multimedia playback services on the market are LCD TV. [0003] Among them, the existing direct-type liquid crystal display devices such as figure 1 As shown, it includes a blue backlight source 11 , a filter panel 13 , and a liquid crystal cell 12 arranged between the blue backlight source 11 and the filter panel 13 . Wherein, the filter panel 13 is provided with a red quantum dot pixel unit 131, a green quantum dot pixel unit 132 and a transparent pixel unit 133, and each pixel unit is adjacent to other two pixel units a...
