Problems solved by technology

This method has the problems of loss of penetration rate and increase of screen thickness and weight
[0004] There is another method on the market, such as Figure 1b As shown, specifically, a layer of PDLC (Polymer Dispersed Liquid Crystal) 4 is added to the structure of the OLED (Organic Light Emitting Diode) display screen 1 to realize the control of mirror surface and non-mirror surface display. Technical difficulties, and cannot be realized in LCD modules

Embodiment 1

[0027] see figure 2 with image 3 , the display device according to Embodiment 1 of the present invention includes a backlight module 100, a display module 200, a first polarizer 300 and a mirror polarizer 500, wherein the backlight module 100 is used to provide the brightness of the backlight of the display device; the display module 200 Used to display images; the first polarizer 300 is located between the backlight module 100 and the display module 200, and is arranged on the lower surface of the display module 200, and is used to convert the light emitted by the backlight module 100 into linearly polarized light; mirror polarized light The sheet 500 has a polarizing function and is arranged on the upper surface side of the display module 200 for transmitting the light emitted by the backlight module 100 while reflecting natural light.

[0028] By arranging the mirror polarizer 500 at the front end of the display device, when the brightness of the backlight source on the ...

Embodiment 2

[0034] The display device of this embodiment also includes a backlight module 100, a display module 200, a first polarizer 300, and a mirror polarizer 500. The difference from Embodiment 1 is that the display device of this embodiment also includes a first polarization function. Two polarizers 400 , the second polarizer 400 is located between the display module 200 and the mirror polarizer 500 . Specifically, the third heat-sensitive adhesive layer 410 is pasted on the outer surface of the display module 200 , and the mirror polarizer 500 is pasted on the second polarizer 400 through the first heat-sensitive adhesive layer 510 to form a dual polarization structure.

[0035] It can be understood that the display module 200 of the present invention may also be an OLED display module. Compared with the prior art, the display device of the present invention does not significantly increase the thickness or weight of the display screen, the cost is relatively low, and it is compatib...

Abstract

The invention discloses a display device which comprises a backlight module, a display module, a first polaroid and a mirror polaroid, wherein the backlight module is used for providing backlight brightness of the display device, the display module is used for displaying frames, the first polaroid is positioned between the backlight module and the display module, arranged on the lower surface of the display module and used for converting light emitted by the backlight module into linear polarized light, and the mirror polaroid with a polarization function comprises a first thermosensitive gel layer, adheres to the outer surface of the display module through the first thermosensitive gel layer and is used for transmitting the light emitted by the backlight module and reflecting natural light. By means of the display device, the thickness, the weight and the cost of a display screen are not increased obviously, and a liquid crystal display module and an OLED display module can be compatible at the same time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device. Background technique [0002] At present, some high-end places in the society often have various appearance mirrors with display functions, taking into account functions such as appearance mirrors and information push display, which can not only meet people's needs for dressing up, but also function as billboards. [0003] Such as Figure 1a As shown, the implementation method is usually to paste a translucent and semi-reflective glass layer 3 on the top of the display screen 1 , and use the front frame 2 of the display screen to fix the glass layer 3 on the upper surface of the display screen 1 . This method has the problems of loss of penetration rate and increase of screen thickness and weight. [0004] There is another method on the market, such as Figure 1b As shown, specifically, a layer of PDLC (Polymer Dispersed Liquid Crystal) 4 is added to the stru...
