Benefits of technology

[0009] It is an object of the present invention to provide a method for manufacturing a plurality of CLC films fast and simply, i.e. brightness enhancement films.

Problems solved by technology

However, the choke point of developing TFT LCD technology is the brightness.
According to the standard of CRT monitors, the brightness for TFT LCD is not enough.
Although plenty of researches are conducted on the solution to improving brightness, such as increasing luminance of backlight source or LCD, i.e. increasing the aperture ratio of TFT LCD or luminance of all components, most of these solutions can not solve the problem without heat dissipating problem and over-consumption of electricity.
It is a better solution nowadays but the costs are more expensive.
And the relative processes are more complicated.

Abstract

A brightness enhancement film for use on a display includes a first substrate, a first light transmitting layer mounted on said first substrate, a second light transmitting layer mounted on said first light transmitting layer, a third light transmitting layer mounted between said first light transmitting layer and second light transmitting layer, and a second substrate mounted on said second light transmitting layer, wherein said first and said second light transmitting layer have a first and a second chiral character, respectively, and said third light transmitting layer has a wide-band chiral character.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a divisional of U.S. patent application Ser. No. 10 / 761,085, filed Jan. 20, 2004, entitled “Method For Manufacturing Brightness Enhancement Film Of Liquid Crystal Display And Structure Thereof.”BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a manufacturing method for a brightness enhancement film, and more particularly to a manufacturing method for a brightness enhancement film of a liquid crystal display (LCD) and the structure thereof. [0004] 2. Description of Related Art [0005] A backlight module, also known as a backlight unit, is generally an optical assembly providing a backlight source for products and applied to digital camera, PDA (Personal Digital Assistant), GPS (Global Positioning System), medical apparatus, notebook, LCD Monitor, and etc. Owing to the TFT LCD panel itself does not have a light-emitting function, it must have a light source mounted in t...
