Problems solved by technology

[0004] However, adding more optical modules to the backlight module will increase the assembly time and make fixing more difficult, and the weight and thickness of the panel will also become heavier and thicker as the number of optical modules increases.
In addition, the diffusion sheet is also prone to wrinkle due to the heating of the lamp tube
Therefore, someone proposed a method to remove the upper and lower diffusion sheets to reduce the weight and thickness. However, removing the diffusion sheet will cause the uniformity of the backlight module to decrease, the appearance quality will deteriorate, and the backlight is easy to detect foreign objects, dirt, and white spots.

Embodiment Construction

[0061] The flat display module, flat display panel, and backlight module according to preferred embodiments of the present invention will be described below with reference to the relevant drawings. For ease of understanding, the component symbols in the following embodiments are the same components as those in the previous embodiment. symbols to illustrate.

[0062] Please refer to FIG. 2 , which is a schematic diagram of the flat panel display module of the present invention. In the figure, the flat display module 20 includes a flat display panel 21 and a backlight module 22 . The flat display panel 21 includes an upper polarizer 111 , a lower polarizer 212 , an upper substrate 113 and a lower substrate 114 . The outermost layer of the lower polarizer 212 has a first diffusion layer 213 . Wherein, the optical haze of the first diffusion layer 213 must be greater than the optical haze of the surface of the upper polarizer 111 . The above-mentioned first diffusion layer 213 ...

Abstract

This invention relates to one plane display module, plane display panel and aphototropism module, wherein, the plane display module comprises one plane display panel and one aphototropism module; plane display panel comprises one upper bias light board and one down bias light board with one first diffusion layer; aphototropism module comprises one light device, one prism slice and one light conductive board; the light device provides one light source with one surface of prism as one dimension prism array structure with upper surface have second diffusion layer to diffuse light source.

Description

technical field [0001] The invention relates to a plane display module, in particular to a plane display module, a plane display panel and a backlight module in which a polarizing plate and a light guide plate have a diffusion layer. Background technique [0002] In recent years, thin display panels have become increasingly popular, and are widely used in home appliances, communication devices, and computer devices. Among them, the development trend of notebook computer panels is to take into account both thinness and high brightness. In the prior art, the backlight module is usually equipped with a prism sheet to concentrate the light energy in the front viewing angle by refraction, and above or below the prism sheet, a diffuser sheet is added to uniform the light, thereby achieving high brightness. Target. [0003] Please refer to FIG. 1 , which is a schematic diagram of a flat display module in the prior art. In the figure, the flat display module 10 includes a flat di...
