Problems solved by technology

[0003] However, when the display panel displays images, as the light path increases, when the light source propagates in the liquid crystal layer, the total energy scattered by it declines significantly, resulting in poor display uniformity

Embodiment Construction

[0038] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] The invention provides a display device, such as figure 1As shown, the display device includes: a liquid crystal display panel 10 , a light source 20 and a light guide assembly 30 . Wherein, the liquid crystal display panel 10 includes an array substrate 11 , a cell-matching substrate 12 , and a liquid crystal layer 13 located between the array substrate 11 and the cell-matching substrate 12 . A polymer network 132 formed by polymerizing polymerizable monomers is mixed in the liquid crystal layer 13 . The light guide assembly 30 is arranged on the side of the array substrate 11 away from the box substrate 12; the light guide assembly 30 includes a top s...

Abstract

The invention relates to a display device. The display device comprises a liquid crystal display panel and a light source. The liquid crystal display panel comprises an array substrate, an opposite-box substrate and a liquid crystal layer. A polymer network formed by polymerizable monomers is mixed in the liquid crystal layer. The display device further comprises a light guide assembly arranged on the side, away from the opposite-box substrate, of the array substrate. The light source is arranged on the side face of the light guide assembly and used for emitting light towards the light guide assembly. The light guide assembly is used for scattering the light emitted by the light source to form an area light source giving out light towards the liquid crystal display panel. The included angle between the direction of light, emitted to the liquid crystal layer, of the area light source and the thickness direction of the liquid crystal display panel is larger than a total reflection critical angel generated when any light is emitted into outside air from the array substrate or the opposite-box substrate. According to the display device, the display uniformity can be improved while the contrast is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In addition to ordinary display, the types of display technology also include transparent display and mirror display. Among them, for transparent display technology, the common transparent display device based on liquid crystal display on the market is to remove the backlight module behind the display panel, and then A light box is arranged on the rear and upper side of the display panel to provide light required for displaying images, but the light transmittance of the display panel based on liquid crystal display is low, resulting in low contrast of the display screen of the display device. In order to improve the transmittance, people in the industry have proposed a liquid crystal transparent display device based on Polymer Stabilized Liquid Crystal (Polymer Stabilized Liquid Crystal). In this display device, the light s...
