Embodiment Construction

[0017] An embodiment of the present invention is to manufacture a direct light-diffusing composition. The single-layer film material composition can be selected from any plastic material including acrylic PMMA (such as polymethacrylic acid), PC polycarbonate, and PS polystyrene as the main component. The percentage by weight of the main component accounts for the composition, and the preferred range is about 70% to 90%; the more preferred range is about 70% to 80%, and its plastic is selected from acrylic PMMA (such as polymethacrylic acid) , or PC polycarbonate.

[0018] As for the additives of the single-layer film material composition comprising titanium dioxide agent and diffusing agent, its percentage by weight, the proportion range of titanium dioxide agent additive for better implementation is about 10% to 15%, and the additive ratio for diffusion agent for better implementation The range is about 10% to 15%, and the additive ratio is adjusted according to the thicknes...

Abstract

A straight down type of light diffusion component is a single layer film used on back light module. It is prepared by 70 ¿C 90 wt % of plastic such as PMPA, PC or PS; 10 ¿C 15 wt % of titanium dioxide and 10 ¿C 15 wt & of dispersing agent.

Description

technical field [0001] The present invention relates to a direct light diffusion composition, especially used in a backlight module, and replaces the existing multi-layer film structure of a light guide plate and a light diffusion sheet with a single-layer film structure. Background technique [0002] Nowadays, commonly used personal computers, notebook computers, handheld communication devices, etc. require light weight and thin volume, and a liquid crystal display unit just meets this requirement. A typical liquid crystal display needs to be provided with a backlight module (backlight module) on the back of the liquid crystal display panel, so as to provide sufficient light source to view the displayed data. Therefore, the backlight module becomes more and more important. [0003] A general backlight module is provided with a light guide plate (light guide plate) in front of the light source, so that light enters the light guide plate to produce a smooth surface; at the s...
