Problems solved by technology

[0004] In addition, for higher display quality and the need to improve the light utilization rate of the light-emitting unit, the light guide plate made of high molecular polymer has lower than expected transmittance, which will inevitably sacrifice the use of light emitted by part of the light-emitting unit. rate, resulting in a decrease in the brightness of the display panel

Embodiment 1

[0028] Embodiment 1: Stereoscopic display device

[0029] First, if Figure 1A As shown, a light guide mother board 11 is provided, which is a glass substrate. Wherein, the light guide motherboard 11 has a first surface 111 and an opposite second surface 112 , and the second surface 112 is further provided with a plurality of scattering stripe patterns 12 . Here, each scattering stripe pattern 12 is embedded in a groove 113 of the light guide motherboard 11 . However, in other embodiments, the scattering stripe pattern 12 can be directly disposed on the second surface 112 of the light guide motherboard 11, such as Figure 1B shown.

[0030] Here, the material of the scattering stripe pattern 12 is not particularly limited, and can be any material that can reduce the occurrence of total reflection. For example, the material of the scattering stripe pattern 12 may be a composite material formed of titanium dioxide and ink or photoresist; however, the invention is not limited ...

Embodiment 2

[0048] Embodiment 2: flat display device

[0049] The light guide plate prepared in Example 1 above can also be applied to the flat display device of this embodiment; the difference is that the flat display device of this embodiment does not need to be provided with the scattering stripe pattern of Example 1, but is used in the light guide plate. The second surface 112 of the light board 1 forms a dot pattern (not shown); meanwhile, the pixel unit 43 of the display panel 4 does not need to be composed of a plurality of sub-pixel units.

[0050] Here, the light guide plate of the present embodiment has the same features as the light guide plate of the embodiment 1, so details are not repeated here.

[0051] In addition, the display device of the aforementioned embodiment 1 and embodiment 2 is not particularly limited, it can be a liquid crystal display device or an organic light emitting diode display device; and it can be applied to monitors, mobile phones, notebook computers,...

Abstract

The invention relates to a display device. The display device comprises a display panel and a light guide plate arranged on a light incident side of the display panel, wherein the display panel comprises a substrate; when the temperature is between 0 DEG C and 150 DEG C, the difference value of expansion rates of the substrate and the light guide plate is between 0% and 0.5%. Besides, the display device further comprises a light emitting unit arranged on one side edge of the light guide plate.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device in which a light guide plate and a display panel have similar expansion rates. Background technique [0002] With the continuous development of electronic products, users have higher and higher requirements for electronic products. In display devices, display quality is one of the items required by users. Among them, the backlight module is an indispensable component of the display device, and the efficiency of the backlight module is one of the factors affecting the display quality. Generally speaking, a backlight module is usually composed of a backplane, a light guide plate, a light source and a multilayer optical film. [0003] The known light guide plates are mostly made of high molecular polymers. However, high molecular polymers have a high thermal expansion coefficient and water absorption rate; therefore, in the process of user use, the thermal energy gener...
