Abstract

The invention relates to a key light guide assembly and a key backlight module thereof, wherein the key light guide assembly comprises a macromolecular base material and a UV (Ultraviolet) hardened material, and the UV hardened material is located on the surface of the macromolecular base material and is provided with a plurality of polyhedron microstructures.

Description

technical field [0001] The present invention relates to a light guide assembly, and in particular to a light guide assembly for a key backlight module. Background technique [0002] With the advent of the information age, communication products such as mobile phones (or mobile phones) have become the most commonly used communication tools at present. In order to meet the needs of consumers, mobile phones are gradually becoming thinner and smaller. In response to this trend, the design of the backlight module of the mobile phone key is more important, not only to achieve a thinner design, but also to take into account the tactile feeling of pressing. [0003] In the button module of the mobile phone, in order to make the upper font bright, a light source (such as a light-emitting diode) is generally placed in the area under the button module that needs to be illuminated, and the light guide component is used to scatter the light, and the scattered light is transmitted to the ...
