touch module

Abstract

The present invention discloses a touch control module, comprising a touch control face and at least one light output module, wherein the touch control face has a first side edge, the light output module has a light outgoing face, the light outgoing face extends along a first side edge, the light output module comprises a light guide unit and a light source, the light guide unit comprises a reflection face, the reflection face is arranged along the first side edge and has opposite first and second ends, the distance between the portion of the reflection face, nearer the first end and the first side edge is greater than the distance between the portion of the reflection face, nearer the second end, the light source and the reflection face are all arranged at the back side of the light outgoing face, the light source is arranged at the first end, the light source generates light, and the light is reflected by the reflection face and output by the light outgoing face.

Description

technical field [0001] The present invention relates to a touch module; specifically, the invention relates to a touch module capable of improving light extraction efficiency and touch performance. Background technique [0002] Technology has always come from human nature. In the current society, all kinds of electronic products are becoming more and more humanized to meet the needs of life. Functions such as thinness, multi-tasking and touch control have become indispensable elements for the development of electronic products. In fact, electronic products with touch functions have gradually penetrated into the lives of modern people. Specifically, the electronic product achieves a touch effect through the touch module. However, how to design a better touch module and effectively improve the touch performance is a major issue nowadays. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an existing touch screen. Generally speaking, a c...

Problems solved by technology

However, in actual situations, the geometric structure 14 has a complex shape and its dimming performance is limited, so that the light cannot be evenly distributed on the touch surface 13

[0004] Furthermore, once the yield rate is not good in the process of manufacturing the geometric structure 14, the touch performance of the touch screen will also be affected.

In addition, the reflection efficiency of the light guide column 12 will also affect the light extraction efficiency of the light.

Based on the above factors, there are still many shortcomings in the traditional touch screen.
