LCD device

Abstract

The invention provides a LCD (liquid crystal display), comprising a first LCD panel, a second LCD panel, and a backlight module, where the first LCD panel is opposite to the second one, the backlight module is between the two panels, the display area of the first LCD panel is more than that of the second one, the backlight module comprises a light source, a light guide plate, a first optical component and a second optical component, the light guide plate comprises a light incoming surface, a first light outgoing surface intersecting the light incoming surface, and a second light outgoing surface opposite to the first light outgoing surface, the light source is opposite to the light incoming surface, the first and second optical components are opposite to the first and second light outgoing surfaces, respectively, and the second optical component is provided with plural microdots.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device capable of double-sided display. 【Background technique】 [0002] Liquid crystal display devices have the advantages of lightness, thinness, and low power consumption, and are widely used in modern information equipment. Since the liquid crystal in the liquid crystal display panel itself does not have luminous properties, in order to achieve the display effect, a light source device must be provided for the liquid crystal display panel, such as a backlight module, whose function is to provide a surface light source with sufficient brightness and uniform distribution to the liquid crystal display panel. The light guide plate is a key component of the backlight module. It must have a good optical design, so that the light guide plate can guide the light emitted by the light source and convert it into a surface light source with a certain brightness...

AI Technical Summary

Problems solved by technology

[0010] In the liquid crystal display device 1, the light shown by the first liquid crystal display panel 10 is guided by the light guide plate 32 from the first part of the light that is uniformly emitted from the first light-emitting surface 36 and reflected by the reflection sheet 47 from the first light-emitting surface 36. The second part of light emitted from the surrounding area is composed of the first part of light distributed on the entire first liquid crystal display panel 10, and the second part of light is only distributed on the surrounding area of ​​the first liquid crystal display panel 10, so the second part of light is distributed on the entire first liquid crystal display panel 10. The display brightness of the surrounding area of ​​a liquid crystal display panel 10 will be higher than the display brightness of the central area of ​​the first liquid crystal display panel 10, so the display brightness of the liquid crystal display device 1 is uneven.
