Problems solved by technology

[0003] The existing liquid crystal display technology is based on the modulation of the polarization state of light by liquid crystals, so the polarizer is one of the necessary accessories for the display. However, the setting of the polarizer will seriously affect the transmittance of the display device, and it will also be used in transparent display applications. Limit the transparency of the display device

Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Most of the existing transparent displays are to divide the display area into a transparent area, and use the transparent area to transmit ambient light to realize the transparent display. Since polarizers are required for the conventional display area, the transmittance of the transparent area is low, and the transparent area will also affect the resolution of the display device, which is not conducive to the design of a display device with high PPI.

[0034] In order to solve the above problems, refer to figure 1 , the present application provides a display panel, which may include: a control module 10 , and a first substrate 11 , a refraction layer 12 and a second substrate 13 arranged in layers.

[0035] The second sub...

Abstract

The invention provides a display panel, a control method of the display panel, and a display device. According to the display panel, the control method of the display panel, and the display device, adisplay status or a non-display status is realized by adjusting the refractive index of a refractive layer, the light-emitting efficiency of the display panel is adjusted by forming a grating structure whose refractive index changes periodically in the display stage, and thus gray scale display is realized, that is, the gray scale display of the display panel does not need to be provided with a polarizer, and the transmittance and transparency of a display product can be improved through the display panel; and ambient light can penetrate through the display panel to realize transparent display, a transparent area is not needed to be divided in a display area separately, the resolution of the display device cannot be affected, and the design of the display device with high PPI is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a control method thereof, and a display device. Background technique [0002] Liquid crystal display is a display device used on a large scale at present. It has a series of advantages such as high color gamut, lightness and thinness, and fast response time. It has mature technologies in theoretical research and practical technology. The liquid crystal display can not only meet the requirements of conventional display, but also have various display modes, such as transparent display, anti-peep display, dual-view display and so on. [0003] The existing liquid crystal display technology is based on the modulation of the polarization state of light by liquid crystals, so the polarizer is one of the necessary accessories for the display. However, the setting of the polarizer will seriously affect the transmittance of the display device, and it will also be ...
