Problems solved by technology

Nowadays, the light source is generally a point light source. Therefore, the light emitted by the light source at the edge of the visible area will form alternating light and dark. If there is an alternating light and dark situation on the light incident surface, these products will have uneven light and unclear images, which cannot satisfy people. needs

Abstract

The invention discloses a light guide plate which comprises a body, a light source and a plurality of micro-nano structures, and is characterized in that the body comprises a light emitting surface and at least one light incident surface; the light source is positioned on the incident surface of the body; the micro-nano structures are distributed on the light-emitting surface side and / or the opposite side of the light-emitting surface, and extend towards the light incident surface and are gradually gathered towards the light source; and the distribution width of the plurality of micro-nano structures close to the light incident surface is smaller than that of the plurality of micro-nano structures far away from the light incident surface, so that incident light of the light guide plate isconverted into uniform light, alternately bright and dark light shadows on the light guide plate are eliminated, and the definition of an edge image of the liquid crystal display screen is improved.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a light guide plate. Background technique [0002] Due to the development of information technology, the demand for various display devices for displaying images is constantly expanding. With the development of liquid crystal displays, the backlight module is an important part of liquid crystal displays. Its role is to supply sufficient brightness and provide distribution A uniform light source enables it to display images normally. A backlight module generally includes a light source, a light guide plate, an optical film, and at least one frame or chassis as a supporting structure for supporting the side and the back of the display device. Backlight modules are divided into side-light type and direct-light type according to the incident position of the light source. The side-light type backlight module means that the light source is set on one side of the light guide ...
