Embodiment Construction

[0071] Some embodiments of the present invention are described in detail as follows. However, the invention may be practiced broadly in other embodiments than those described in detail, and the scope of the invention is not limited only by the following claims.

[0072] The present invention mainly provides a planar light source structure for a flat panel display, which includes a first light source and a first light guide plate. The above-mentioned first light guide plate has a light emitting surface, which is used to guide the light emitted by the first light source into the first light guide plate and uniformly emit from the light emitting surface. The first light guide plate is used as a substrate of the flat panel display, and its material is transparent plastic.

[0073] The above planar light source structure includes a polarizing plate located between the aforementioned first light source and the first light guide plate. When the above-mentioned flat panel display is...

Abstract

The planar light source structure for planar display includes one light guiding plate and one light source. The light guiding plate is made of transparent plastic. When the light guiding plate is used as back light source, it is used as the lower base plate of the liquid crystal display panel. When the light guiding plate is used as front light source, it is used as the upper base plate of the liquid crystal display.

Description

technical field [0001] The invention relates to a planar light source structure, in particular to a planar light source structure for a flat panel display. Background technique [0002] Surface light sources are usually used on liquid crystal displays. A surface light source irradiated from the rear of the liquid crystal display panel is called a backlight, and a surface light source irradiated from the front of the liquid crystal display panel is called a front light source. LCDs using a backlight are transmissive, while LCDs using a front light are reflective. Whether it is a transmissive or reflective LCD, a high-brightness and stable light source is essential. [0003] A traditional transmissive liquid crystal display, such as figure 1 As shown, there is a flat light guide plate 102, which is used to redirect the light from two light sources 104-1 and 104-2 on the two end surfaces of the light guide plate and guide them to the light output surface for the liquid cryst...
