Problems solved by technology

However, the transmittance of the polarizer is lower than 50%, which will significantly reduce the light output rate of the display device and result in an insufficiently wide color gamut
Therefore, in order to achieve wide color gamut (Adobe RGB) and wide color gamut (such as DCI P3), the design of display devices at this stage still needs to be improved

Abstract

The invention provides a display device. The display device comprises a blue backlight source and a display panel, wherein the blue backlight source can emit blue light; the display panel is arrangedon the light emitting side of the blue backlight source, and comprises an array substrate, a liquid crystal layer and a color film substrate which are arranged in a stacked mode, wherein the liquid crystal layer is composed of a cholesteric liquid crystal and can be used for regulating and controlling blue light; the color film substrate comprises a red color film layer, a green color film layer and a blue color film layer which are arranged on the same layer, wherein the red color film layer and the green color film layer are photoluminescence layer; the red color film layer emits red light under the excitation of the blue light; the green color film layer emits green light under the excitation of the blue light, wherein the display device does not comprise an upper polaroid and a lower polaroid. According to the display device provided by the invention, the blue light modulation effect of the liquid crystal layer formed by the cholesteric liquid crystal is more accurate than that ofwhite light, so that the two sides of the display panel do not need to be provided with polaroids respectively, and the light emitting control of the display device also can be realized, and thereforethe light emitting efficiency of the display device can be greatly improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, the present invention relates to a display device. Background technique [0002] At present, liquid crystal display (LCD) display devices of electronic devices such as mobile phones, tablet computers, and smart watches generally need to use two polarizers with vertical polarization directions to realize the modulation of the natural light emitted by the white backlight source by the liquid crystal layer. However, the transmittance of the polarizer is lower than 50%, which will significantly reduce the light extraction rate of the display device and result in an insufficiently wide color gamut. Therefore, in order to realize a wide color gamut (Adobe RGB) and a wide color gamut (such as DCI P3), the design of the display device at the present stage still needs to be improved. Contents of the invention [0003] The present invention has been accomplished based on the ...
