Embodiment Construction

[0073] figure 1 It is a schematic cross-sectional view of a light guide plate in an example of the present invention. Please refer to figure 1 The light guide plate 100 has a light-emitting surface 102, and the light-emitting surface 102 is provided with a supporting portion 110 for supporting a display panel (not shown). The supporting portion 110 has an inner side surface 113 and a supporting surface 114 adjacent to each other, wherein the supporting surface 114 is used for supporting the display panel. The inner side surface 113 is connected between the light-emitting surface 102 and the bearing surface 114 and is perpendicular to the light-emitting surface 102 and the bearing surface 114.

[0074] Generally speaking, most of the light entering the light guide plate 110 exits through the light exit surface 102 to form a surface light source. In addition, the light guide plate 110 has a carrying portion 110 that can directly carry the display panel, so that the display device ...

Abstract

The invention discloses a display device and a light guide plate thereof. The light guide plate is suitable for bearing a display panel, and composed of an out-light surface and at least one bearing part arranged on the edge of the out-light surface. The bearing surface is suitable for bearing the display panel. An inner side surface is connected with the bearing surface and the out-light surface, and provided with a plurality of micro structures. The light leakage of the bearing part is reduced by the light guide plate. The invention also provided with a light guide plate with the inner side surface inclined relative to the out-light surface and two kinds of display devices comprising the above two kinds of light guide plates.

Description

Technical field [0001] The invention relates to a display device, and in particular to a display device with a backlight module and a light guide plate thereof. Background technique [0002] The liquid crystal display device is one of the flat display devices with a relatively high penetration rate. The main components are a liquid crystal display panel and a backlight module. The backlight module is used to provide a surface light source to the liquid crystal display panel as a display light source required by the liquid crystal display panel. Therefore, the quality of the surface light source provided by the backlight module is closely related to the display quality of the liquid crystal display device. [0003] The backlight module can be divided into a direct type backlight module and a side light incident type backlight module. The side light incident type backlight module includes a light guide plate and a light emitting element arranged beside the light incident surface of t...
