Abstract

The invention relates to a capacitive touch screen and a manufacture method thereof. A touch control chip is not required to undergo a packaging test, and a chip wafer is only required, so that compared with a touch control chip adopted by a traditional touch screen module, the capacitive touch screen is reduced in costs of chip packaging and package test. Simultaneously as the area of the chip is small, compared with the traditional touch control chip with a package shape, the capacitive touch screen occupies small space. The overall material cost of the capacitive touch screen can be effectively reduced, simultaneously the capacitive touch screen is easy to produce, the requirement on the manufacture technology of the capacitive touch screen is reduced, and the product yield is improved.

Description

technical field [0001] The invention relates to a capacitive touch screen and a manufacturing method thereof, in particular to a capacitive touch screen with a transparent medium and a light-shielding layer and a manufacturing method thereof. Background technique [0002] At present, capacitive touch screens have become the main components of human-computer interaction in the market, and can provide better user experience effects than traditional resistive touch screens and infrared touch screens. Therefore, it is more and more used in portable consumer electronic products such as mobile phones, MIDs, and tablets, and has become an indispensable main component, among which the most representative projected capacitive screen. At present, the main components of the projected capacitive screen are cover lens, touch sensor, and flexible circuit board (FPC), and the touch control chip is an indispensable part in the capacitive touch control system. According to the actual locati...
