Abstract

The invention provides a capacitive touch screen and a manufacturing method of the capacitive touch screen. The capacitive touch screen comprises a transparent medium, a plurality of induction electrodes arranged on the lower surface of the transparent medium, and a touch control chip bound to the lower surface of the transparent medium, wherein the induction electrodes are arranged into a two-dimensional array, the touch control chip is connected with each induction electrode through a wire, and weight of the touch screen is reduced on the premise that multi-point touch control is achieved. Manufacturing cost is reduced, noise is remarkably reduced, and the signal-to-noise ratio is improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a capacitive touch screen and a manufacturing method thereof. Background technique [0002] At present, capacitive touch screens are widely used in various electronic products, and have gradually penetrated into various fields of people's work and life. The size of capacitive touch screens is increasing day by day, from 3 inches to 6.1 inches for smart phones, to about 10 inches for tablet computers, and the application fields of capacitive touch screens can be extended to smart TVs. However, the existing capacitive touch screen generally has problems such as poor anti-interference performance, low scanning frame rate, high production cost, and heavy touch screen. Contents of the invention [0003] In view of this, embodiments of the present invention provide a capacitive touch screen and a manufacturing method thereof, which can solve at least one of the above problems. [00...
