Embodiment Construction

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] figure 1 A schematic structural diagram of a touch panel is provided for the present invention. It includes a liquid crystal module 1, a sensor 2, a cover plate 3, an optical double-sided adhesive tape 4 and a flexible circuit board 5; the liquid crystal module 1 is used for displaying images, and it includes devices such as a liquid crystal display and a display control chip. The liquid crystal display is preferably an LCD display. It has fast response speed, good contrast, high brightness, large viewing angle, and rich colors; the sensor 2 includes a conductive substrate, and a copper film is sputtered on the conductive substrate through a coating process, and the copper film is treated by yellow light. The copper film signal line is formed by the process, and the copper film signal line is processed and connected with the transparent c...

Abstract

The invention relates to a manufacturing method of a variable array capacitor and an electromagnetic dual-touch sensing panel. The manufacturing method can be made to have a simplified touch module structure, thereby reducing the manufacturing cost, and the obtained touch display panel has a good display effect.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a method for manufacturing an inductor capable of both capacitive and electromagnetic double touch sensing functions. Background technique [0002] At present, touch display is used in a wide range of fields due to its advantages of convenient operation and intuitiveness, especially computers, mobile phones, vehicle control systems, POS machines, and various fields of human-computer interaction. The sensors used in the current touch display mainly include capacitive touch sensors and electromagnetic induction touch sensors. Capacitive touch technology is mainly used in products that are directly touched by fingers, such as mobile phones, computers, video playback terminals, etc. Inductive touch technology is mainly used in products that use pens that emit electromagnetic signals to write, such as electronic whiteboards and children's learning machines. [0003] These two different ...
