Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0031] In order to solve the installation problem of the front camera of the full-screen mobile phone, a method of opening a hole in the display area of ​​the liquid crystal display screen to place the camera can be adopted. There are two ways to open the liquid crystal display: through hole and blind hole. The through hole opens up the backlight module of the liquid crystal display and the liquid crystal display panel, while the blind hole only opens up the backlight module of the liquid crystal display. Compared with blind holes, it has higher light transmittance. However, in actual production, the opening area of ​​the through hole is larger than that of the blind hole, and it is not as good as the blind hole in terms of increas...

Abstract

The invention discloses a liquid crystal display screen and a display device, which belong to the technical field of display. The liquid crystal display screen comprises a liquid crystal display panel, a backlight module, sealing glue and a first polaroid, the backlight module is located on one side of the liquid crystal display panel, the first polaroid is located between the liquid crystal display panel and the backlight module, a first through hole is formed in the backlight module, a second through hole is formed in the first polaroid, a blind hole is defined by the first through hole, thesecond through hole and the liquid crystal display panel, photosensitive devices such as a camera can be arranged in the blind hole, the sealing glue is bonded to the inner wall of the blind hole andfixedly connected with the backlight module, the liquid crystal display panel and the first polaroid in a bonding mode, light emitted by the backlight module can be prevented from being emitted intothe blind hole from the position between the backlight module and the liquid crystal display panel, and light is prevented from influencing a photosensitive device in the blind hole.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a liquid crystal display screen and a display device. Background technique [0002] With the development of display technology, terminals such as mobile phones are developing in the direction of full screen. In terminals such as full-screen mobile phones, in order to place devices such as cameras or sensors, a panel structure with holes in the display area of ​​the liquid crystal display is usually adopted, so that the mobile phone can achieve a higher screen-to-body ratio. [0003] When a photosensitive device such as a camera or a sensor is placed in a hole in the display area of ​​the liquid crystal display, the light emitted by the backlight assembly of the liquid crystal display often leaks into the hole, affecting the normal operation of the photosensitive device placed in the hole. Contents of the invention [0004] Embodiments of the present disclosure provid...
