Touch screen, touch display device and production method of touch screen

Abstract

The invention discloses a touch screen, a touch display device and a production method of the touch screen. The touch screen comprises first electrodes, second electrodes, second electrode connecting wires, first electrode connecting wires, insulating blocks and a protective layer. The first electrodes, the second electrodes and the second electrode connecting wires are arranged on a first level. The first electrodes and the second electrodes intersect with each other. The second electrode connecting wires connect the adjacent second electrodes at the intersection. The first electrode connecting wires on a second level connect the adjacent first electrodes at the intersection in an overlapping manner. The insulating blocks located between the first electrode connecting wires and the second electrode connecting wires are overlapped with the first electrode connecting wires. The arrangement size of the insulating blocks in the direction of the first electrodes is smaller than the length of each first electrode connecting wire, and the arrangement size of the insulating block in the direction of the second electrodes is not smaller than the width of each first electrode connecting wire. The protective layer is arranged above the structure of the first level, the insulating blocks and the second level. Light transmissivity of the touch screen is improved greatly, macroscopic color effect is improved, and touch resistance between the first electrodes is also reduced.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch screen, a touch display device and a manufacturing method of the touch screen. Background technique [0002] As an input medium, a touch screen provides users with better convenience than a keyboard and a mouse. According to different implementation principles, touch screens can be divided into resistive, capacitive, surface acoustic wave, infrared, bending wave, active digital converter, and optical imaging. At present, resistive and capacitive touch screen technologies are widely used. In the structures of these two touch screens, transparent metal electrodes need to be provided. [0003] Compared with resistive touch screens, capacitive touch screens have the advantages of fast response time, good reliability and high durability. Capacitive touch screens include surface capacitive and inductive capacitive, and inductive capacitive touch screens can be d...
