Problems solved by technology

Therefore, the viewing angle of the blue primary color light with a single direction is much smaller than that of the scattered red and green primary color light, which causes the problem of color cast in the display panel under multiple viewing angles.

Embodiment 1

[0037] For a display panel 200 provided in Embodiment 1 of the present invention, please refer to Figure 2a As shown, in order to more clearly express the local structure of the quantum dot display panel 200, along Figure 2a After the cross-section in the middle A direction and the partial zoom-in at M, please refer to Figure 2b As shown, the quantum dot display panel 200 includes: a lower substrate 211 , a middle substrate 212 , an upper substrate 213 , a liquid crystal layer 220 and a quantum dot layer 230 .

[0038]Specifically, the liquid crystal layer 220 is encapsulated between the lower substrate 211 and the middle substrate 212, and the amount of backlight light transmission is controlled by the inversion state of the liquid crystal molecules in the liquid crystal layer 220. The quantum dot layer 230 is arranged above the liquid crystal layer 220 and encapsulated in the middle substrate. 212 and the upper substrate 213, the quantum dot layer 230 includes a pluralit...

Embodiment 2

[0062] For a liquid crystal display device provided by Embodiment 2 of the present invention, please refer to image 3 As shown, the liquid crystal display device 300 includes the display panel 200 provided in the first embodiment above, and further includes: a backlight module 301 arranged under the display panel 200 and used to provide a blue backlight.

[0063]In summary, the application of the present invention provides a display panel and a liquid crystal display device encapsulating a quantum dot layer, wherein, in the provided display panel, the substrate encapsulated in the blue sub-pixel unit is configured in a non-planar shape. When the blue light transmitted by the blue sub-pixel unit passes through the substrate with a non-planar shape, the blue light is emitted from the blue sub-pixel unit at different exit angles and in the form of divergent light, which is different from the excited blue light emitted at different exit angles. Red light and green light together ...

Abstract

The embodiment of the invention provides a display panel packaged with a quantum dot layer and a liquid crystal display device; according to the display panel packaged with the quantum dot layer, the display panel is configured with several pixel units, and the pixel units are composed of sub-pixels in different colors, the liquid crystal layer controls the backlight transmission transmitted to every sub-pixel; sub-pixels in different colors include red sub-pixel units packaged with quantum dot materials, green sub-pixel units and blue sub-pixel units configured with transparent mediums or air layers, wherein the substrate surface packaged with the blue sub-pixel units is configured to be a non-plane shape. When the blue light in the blue sub-pixel units is configured with a non-planar substrate, the blue light is transmitted according to the non-parallel direction, the blue light, the red and green lights acquired by the excitation of the blue light and presenting dispersing lights can commonly realize the color display of the pixel unit, thus the color cast of every pixel unit under multiple views can be solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a quantum dot display panel and a liquid crystal display device. Background technique [0002] A liquid crystal panel in the prior art includes a liquid crystal layer sealed between two parallel glass substrates, and a color filter placed above the liquid crystal layer. When the liquid crystal panel is used to display the picture, the white light source is used as the backlight, and the switching state of the liquid crystal molecules controlled by the voltage in the liquid crystal layer is used to control the on-off of the backlight light. When the backlight light passing through the liquid crystal layer passes through the color filter, Only the light in the specific wavelength range of the color filter can pass through and realize the screen display, and the light in other wavelength ranges is absorbed or reflected by the color filter, so the transmittance of the ...
