Embodiment Construction

[0017] The present invention provides a composite flexible light guide plate and a backlight source. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 As shown, a composite flexible light guide plate, which includes a light guide layer 21, a light-increasing diffusion layer 211, a reflective layer 212, and a light source 22. 21 , the light source 22 is disposed at one end of the light guide layer 21 . The structure of the traditional light guide plate is too complex and heavy, resulting in a long structured light path and low light utilization efficiency. Therefore, the present invention is made by thinning and laminating the light guide layer 21, the light-enhancing diffusion ...

Abstract

The invention discloses a composite flexible light guide plate and a backlight. The composite flexible light guide plate comprises a light guide layer, a light enhancement diffusion layer, a reflective layer and a light source, wherein the light enhancement diffusion layer is arranged on the upper part of the light guide layer; the reflective layer is arranged on the lower portion of the light guide layer; and the light source is arranged at one end of the light guide layer, wherein one end, close to the light source, of the light guide layer is provided with a light entrance surface for receiving light. A reflective surface is also arranged between the light guide layer and the reflective layer. A light exit surface corresponding to the reflective surface is arranged between the light guide layer and the light enhancement diffusion layer for uniformly leading out the light in the light guide layer, and the light entrance surface is perpendicularly connected to the reflective surface and the light exit surface. According to the invention, through composite production of the light guide plate, a reflective film and a light enhancement diffusion film of the backlight, assembled parts of the backlight are greatly reduced; the light path is optimized; the light utilization rate and the light extraction efficiency are raised; the structure is simple; bending is easy; and liquid crystal display devices are further promoted to develop towards being flexible, ultrathin and frameless.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a composite flexible light guide plate and a backlight source. Background technique [0002] Liquid crystal display technology has become the mainstream display technology in the field of display by virtue of its mature technology, low cost and excellent performance. The liquid crystal display is a passive light-emitting device, which does not emit light itself and must be illuminated by a backlight added behind it. . The backlight source and the liquid crystal display screen are combined to form a liquid crystal display module. [0003] The existing backlight is generally composed of reflective film, light guide plate, diffusion film, light enhancement film, composite film and light source. Its working principle is to use the light guide plate to guide the light from the light source from the light incident surface of the light guide plate to In the light guide ...
