Benefits of technology

[0010]A light source module is provided, for reducing the hot spots generated during assembly or transport due to collisions of the light guide plate, thereby increasing yield and decreasing production costs.
[0011]A display module having a favorable display quality is also provided.
[0014]In summary, since the length of the grooves or the protruding patterns on the light guide plate is smaller than the length of the light guide plate, during assembly or transport of the light source module, the grooves or the protruding patterns on the light guide plate can decrease the area for which the light guide plate may collide or cause friction with other components (such as an optical film set disposed above the light guide plate or a reflector disposed below the light guide plate). Consequently, the light source module can provide a more favorable planar light source, thereby improving the display quality of the display module, improving the yield of the light source module and the display module, and decreasing production costs.

Problems solved by technology

Consequently, not only is the display quality of the LCD apparatus compromised, the production costs are increased because extra optical films are needed to solve the hot spot issue.

Embodiment Construction

[0034]FIG. 3 represents a schematic diagram illustrating a display module in accordance with one embodiment of the invention. FIG. 4A represents a schematic side views of a backlight module of the display module depicted in FIG. 3. Referring concurrently to FIGS. 3 and 4A, a display module 300 includes a display panel 400 and a light source module 500, in which the light source module 500 is disposed on a side of the display panel 400, for example below the display panel 400. The light source module 500 includes a light guide plate 510 and a light source 520. For example, the light source 520 can be a plurality of point light sources disposed on at least one side of the light guide plate 510, and the point light sources can be foinied by a plurality of light emitting diodes (LEDs) for providing light. However, the invention is not limited thereto. In other embodiments of the invention, the light source 520 can be other types of light sources. Typically, light emitted from the light ...

Abstract

A light source module including a light guide plate and a light source is provided. The light guide plate has a light incident surface and a light emitting region, and the light guide plate has a plurality of grooves or protruding patterns thereon. The length of the grooves or the protruding patterns is smaller than the length of the light guide plate. The light source is disposed on the light incident surface of the light guide plate, and the grooves or the protruding patterns of the light guide plate are disposed beside the light incident surface.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 98124889, filed Jul. 23, 2009. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention generally relates to a light source module and a display module, and more particularly to a side incident type light source module and a display module having the side incident type light source module.[0004]2.
