Problems solved by technology

[0005] However, what follows is that the gap between the display substrate 1 and the film material of the backlight module 2 is getting smaller and smaller. The gap between them is generally about 1.0mm, such as figure 1 However, in the ultra-thin liquid crystal display device, the gap range that can be reserved between the display substrate 1 and the film material of the backlight module 2 is only between 0.1mm and 0.3mm, and the consequence brought about by this is that the film material and the backlight module 2 It shows that adhesion between the substrates 1 is easy to occur, and Newton rings (Newton rings) phenomenon is easy to occur, such as figure 2 As shown, seriously affect the quality of the product

Embodiment 1

[0031] This embodiment provides a display device, such as image 3 As shown, the display device includes a display substrate 1 and a backlight module 2 that are arranged oppositely, and a transparent material that enables the display substrate 1 and the backlight module 2 to repel and separate is provided between the opposing surfaces of the display substrate 1 and the backlight module 2 .

[0032] Among them, the transparent material that can make the display substrate 1 and the backlight module 2 repel and separate is the same-sex magnetic powder particles, and the same-sex magnetic powder particles are evenly arranged between the opposite surfaces of the display substrate 1 and the backlight module 2, forming a image 3 The magnetic powder particle layer 3 is shown. The magnetic powder particles of the same sex here may be both positive magnetic powder particles or negative magnetic powder particles, which are not limited here. Moreover, the use of transparent isotropic m...

Embodiment 2

[0040] This embodiment provides a display device. The difference between this embodiment and Embodiment 1 lies in that the backlight module of this embodiment is also provided with magnetic powder particles of opposite sex.

[0041] In the display device of this embodiment, transparent heterosexual magnetic powder particles are arranged between the lower surface of the film material group and the upper surface of the light guide plate, so that the film material group inside the backlight module and the light guide plate are attracted to each other. The heterosexual magnetic powder particles here can be positive magnetic powder particles, and the other is negative magnetic powder particles. The specific polarity of the magnetic powder particles on the surface of the film group and the light guide plate can be flexibly set according to the needs. , there is no limitation here.

[0042] Among them, the same-sex magnetic powder particles between the opposite surfaces of the display ...

Embodiment 3

[0047] This embodiment provides a display device. The difference between this embodiment and Embodiment 1 or Embodiment 2 lies in that the location of the isotropic magnetic powder particles is different.

[0048] In the display device of this embodiment, the display substrate includes a polarizer arranged on the side of the array substrate close to the backlight module, and the same-sex magnetic powder particles are doped in the polarizer and coated on the upper surface of the film material group. In this embodiment, the same-sex magnetic powder particles shown on the substrate in embodiment 1 or embodiment 2 are directly formed into the glue of the polarizer, and then the polarizer is formed, which can reduce the probability of falling off of the same-sex magnetic powder particles and ensure the same-sex magnetic powder particles. repulsive force.

[0049] Preferably, the same-sex magnetic powder particles are evenly doped, and the doping density of the same-sex magnetic pow...

Abstract

The invention belongs to the technical field of display and particularly relates to a display device. The display device comprises a display substrate and a backlight module which are opposite. A transparent substance which can allow the display substrate and the backlight module to repel each other and separate from each other is disposed between the opposite faces of the display substrate and the backlight module. The display device has the advantages that Newton rings can be effectively eliminated or avoided, and good display effect is achieved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display device. Background technique [0002] A Liquid Crystal Display (LCD for short) is mainly composed of a display panel and a backlight module. The liquid crystal display device is a passive light-emitting device, because the liquid crystal in the display panel does not emit light itself, so a backlight module needs to be provided to provide a light source for the display panel to realize image display. [0003] Wherein, the display panel includes components such as a display substrate, a flexible connecting wire, and a printed circuit board (PCB for short), and the printed circuit board is connected to the display substrate through a flexible connecting wire. The backlight module includes backplane, reflector, light guide plate (LGP for short), film material group, LED light bar, fixing tape and other components. [0004] With the continuous development of ...
