Problems solved by technology

[0007] The purpose of the present invention is to solve the conventional backlight module, a large amount of light energy in order to achieve uniform light output, and use optical effect film such as prism sheet, diffuser plate, reflector plate, etc., but most of the light energy is refracted repeatedly Loss in the process of reflection and re-reflection, and there is a problem of being wasted by illuminating the opaque part of the panel of the liquid crystal display, thus creating a non-comprehensive and selected plurality of specific positions to emit light, and the emitted light beam can also be obtained by The controlled plural parallel lights are combined to form a backlight module at a concentrated azimuth angle, which emits to the opening of the panel of the liquid crystal display. The present invention can omit the prism sheet, diffuser plate, reflector, etc. in the known backlight module. relatively reduce the cost

Embodiment Construction

[0054] The present invention is a light guide plate with a similar triangular prism structure. As shown in Figure 1, the arrangement of the triangular prisms 13 is a neatly arranged obtuse triangle, wherein D is the width of the bottom surface 14 of the triangular prism, and the bottom surface of the triangular prism is The width just corresponds to the distance of the opening 20 of the panel of the liquid crystal display, so that the light emitted by the total reflection in the quasi-triangular prism 13 just corresponds to the opening 20 of the panel of the liquid crystal display, so that the light energy is effectively used, and the brightness can be improved accordingly. Improve and improve the picture quality of LCD monitors.

[0055] With Figure 2 and Figure 6-1 As shown, it is one of various light angles entering it, wherein the light is injected into the light guide plate 11 by the light source 10, and then the incident light 12 of an angle θ is generated in the light ...

Abstract

The invention relates to a triangle prismatic optic platform, which adapts common or parallel illuminating source to shine optical surface of the optic platform. Each optical outlet position of exit optical beam reflects or refracts totally through triangle prismatic optic platform special separation angle. The distance of exit optical beam centre-line equals to or is less than the distance of LCD display platform adjacent opening. Complex parallel exits vertical optical line of optic platform by controlling complex specific position. The common illuminating source directs light to triangle prism through the LCD opening. The optical energy is catched and exited most of the entire reflection within the optic platform repeatedly.

Description

technical field [0001] The light guide plate with a triangular prism-like structure of the present invention is related to the use of prism sheets, diffusion plates, reflectors and other optically effective diaphragms in order to overcome the conventional backlight module. Most of the energy is lost in the process of repeated refraction and re-reflection, and there is a problem of being wasted due to the problem of irradiating the opaque part of the LCD panel, creating a non-comprehensive and selected complex Light is emitted from a specific position, and the light beams can also be formed at a concentrated azimuth angle by the cooperation of a plurality of controlled parallel lights, and the backlight module is emitted to the opening of the panel of the liquid crystal display, and the present invention is complicated to integrate the conventional multi-chip backlight module structure, directing the invention into simplified modules. Background technique [0002] Most of th...
