Problems solved by technology

[0005] However, if there is a large-area touch capacitive touch screen, and this single-channel scanning method is slow, it will affect the processing speed of the touch screen.
Moreover, in the current design of the driving circuit of the touch panel, the purpose of multi-finger touch is often achieved through multiple driving lines, such as multiple scanning lines and multiple sensing lines. However, the size of the touch panel The larger it is, the more driving lines it needs, which also causes the area of ​​the driving circuit of the touch panel to increase accordingly.

Abstract

The invention discloses a touch panel, a preparation method thereof and a touch device. The touch panel comprises a plurality of transmitting electrode channels and a plurality of receiving electrode channels, each emission signal line is selectively connected with at least one emission electrode channel, and the corresponding emission signal line combination modes on the emission electrode channels are different; each receiving signal line is selectively connected with at least one receiving electrode channel, and the corresponding receiving signal line combination modes on the receiving electrode channels are different; a first diode is arranged between each receiving signal line and the corresponding electrically connected receiving electrode channel, and a second diode is arranged between each transmitting signal line and the corresponding electrically connected transmitting electrode channel.

Description

technical field [0001] The present application generally relates to the field of touch technology, and in particular, relates to a touch panel, a preparation method thereof, and a touch device. Background technique [0002] Touch screen, also known as "touch screen" and "touch panel", is an inductive display device that can receive input signals such as contacts. The touchscreen is located on the display. [0003] The capacitive touch screen is provided with emitting electrodes and sensing electrodes made of transparent conductive materials, and the emitting electrodes and sensing electrodes are insulated from each other. When touching the screen, due to the electric field in the human body, a coupling capacitance is formed between the finger and the emitting electrode and the sensing electrode in the touch screen; due to the capacitance change of the touch point, an induced current flows to the touch point in the emitting electrode and the sensing electrode, The position ...
