Abstract

The invention discloses a touch panel and a manufacturing method thereof. Different from a method of printing a black matrix on a cover glass by monolithic printing and then abutting the cover glass with a touch sensing structure, a method of using a yellow light lithography process is provided to replace the method, a black matrix photoresist is used to directly make a shading layer on the touch sensing structure, to cover a conductive circuit of a frame region. Then concave positions of the shading layer, exposed out of a sensing region are filled by a filling layer, and height of the filling layer is flushed with height of the shading layer. The touch panel can prevent fitting bubbles generated by printing segment difference, defects on appearance of the panel are reduced. Since the yellow light lithography process can make thickness of the shading layer reduce, touch efficacy is improved. the touch panel can be matched with multi-layout design, and capacity is greatly improved.

Description

technical field [0001] The present invention relates to a touch panel and a manufacturing method thereof, in particular to a touch panel and a manufacturing method thereof capable of improving the printing step difference of a black matrix. Background technique [0002] Thanks to the advancement of science and technology, portable electronic devices can be seen everywhere in people's lives, such as notebook computers, tablet computers, smart phones, etc., and with the increase of users' dependence, the functions of portable electronic devices are also It has become increasingly powerful; the common feature of such products is that they have a display screen, which can display various multimedia audio and video to users. Furthermore, in recent years, the trend of portable electronic devices is to provide a larger screen for touch operation, which makes the operation more convenient and flexible for consumers. [0003] Generally speaking, touch screens can be divided into res...
