Embodiment Construction

[0043] The invention provides a light guide plate and a backlight module using the light guide plate. The main purpose of the light guide plate is to guide the direction of light and to distribute the output light of the backlight module evenly. In a preferred embodiment, the backlight module is used for a liquid crystal display device. However, in different embodiments, the backlight module can also be used for computer keyboards, mobile phone buttons, billboards and other devices requiring planar light sources. Furthermore, the present invention also includes a liquid crystal display device using the light guide plate. In a preferred embodiment, the liquid crystal display device of the present invention includes a color liquid crystal display device. However, in different embodiments, the liquid crystal display device of the present invention may also include a monochromatic liquid crystal display device. The liquid crystal display device mentioned here generally refers t...

Abstract

The invention provides a light conductive board and the backlight module using the light conductive board. The light conductive board is corresponding to the light source module of the backlight module. The light conductive board mainly contains the board, a number of microstructures and a number of convex structures. The board is installed nearby the light source module, and including the microstructure surface. The microstructure and convex structure are installed above the microstructure surface, in which the convex structure height is higher than the microstructure height, and between the adjacent convex structures having a number of microstructures.

Description

technical field [0001] The present invention relates to a light guide plate and a backlight module using the light guide plate; more specifically, the present invention relates to a light guide plate for liquid crystal display devices and a backlight module using the light guide plate. Background technique [0002] Liquid crystal display devices have been widely used in liquid crystal televisions, computers, mobile phones and personal digital assistants (Personal Digital Assistant, PDA). Liquid crystal display devices with the advantages of thinness, lightness, power saving, low radiation, etc., have been continuously expanded due to their size becoming larger and product specifications getting better and better. The backlight module is one of the important components of the liquid crystal display device. Since the liquid crystal material in the liquid crystal display device itself is not luminescent, it is necessary to provide light through the backlight module to achieve ...
