Abstract

This invention discloses a method of forming an uneven structure on a substrate. Use a hard tool to penetrate into a mold to cut a first trench and a second trench in an order on a surface of a mold, wherein the hard tool has a smoothly-curved shape such that the transverse width of each of the first trench and the second trench increases as the penetrating depth of the hard tool increases, wherein when each of the first trench and the second trench marches along a first direction, the penetrating depth of the hard tool is controlled by repeating moving the hard tool up and down to cut the mold such that the transverse width of each of the first trench and the second trench varies according to the controlled penetrating depth of the hard tool, wherein the first trench and the second trench completely overlap with each other with no space therebetween. Then, use the surface of the mold to emboss a thin film on a substrate.

Description

technical field [0001] The present invention relates to optical substrates with structured surfaces, in particular to optical substrates for brightness enhancement and diffusion, and more particularly to brightness enhancement and diffusion substrates for use in flat panel displays with planar light sources. Background technique [0002] Flat panel display technology is generally used in television monitors, computer monitors and portable electronic displays (such as mobile phones, personal digital assistants (PDAs), digital cameras, digital tablets, etc.). A liquid crystal display (LCD) is a flat panel display that displays liquid crystal (LC) modules with an array of pixels to image images. [0003] figure 1 An example of an LCD display is shown. The backlit LCD 10 includes a liquid crystal (LC) display module 12 , a planar light source in the form of a backlight module 14 , and a number of optical films sandwiched between the LC module 12 and the backlight module 14 . ...
