Problems solved by technology

Due to the large number of touch drive electrodes, more touch drive electrode leads and more lead pins are required to connect them to the touch drive circuit, which increases the process difficulty to a certain extent.
In addition, too many pins increase the production cost, and will reduce the bonding yield between the touch electrode leads and the touch drive circuit, and are prone to problems such as poor curing after bonding.

Embodiment Construction

[0015] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown.

[0016] figure 1 A schematic diagram of the structure of the first touch electrode of the touch screen in the prior art is shown. Such as figure 1 As shown, this touch electrode structure is a group (10) of touch driving electrodes Tx1-Tx10 corresponding to one touch sensing electrode Rx1, forming a touch electrode unit (only one touch electrode unit is shown in the figure ), wherein each touch driving electrode is independently connected by a single touch driving electrode lead, that is, 10 touch driving electrodes Tx1-Tx10 are independently connected by 10 touch driving electrode leads 101-110, and each touch The touch sensing electrodes Rx1 in the control electrode unit are connected through a touch sensing electrode lead 201 . Generally, the touch driving electrode leads 101 - 110 and the...

Abstract

The invention discloses a touch screen which comprises a plurality of touch electrode units and touch electrode leads. The touch screen is characterized in that each touch electrode unit comprises a touch drive electrode and M touch sensing electrodes; the touch electrode leads comprise a plurality of touch drive electrode leads and M touch sensing electrode leads, each touch drive electrode lead is connected with the corresponding touch drive electrode in a one-to-one corresponding mode, each touch sensing electrode lead of the M touch sensing electrode leads is connected with one of the M touch sensing electrodes of each touch electrode unit, wherein M is a positive integer larger than or equal to five. Compared with the prior art, the touch screen has the advantages that the number of the touch drive electrodes can be effectively reduced under the condition of keeping touch precision unchanged, so the number of pins can be effectively reduced by approximately 40%-50%; in addition, the touch sensitivity can be improved under the condition of keeping the number of the pins unchanged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch screen and a touch control device. Background technique [0002] Currently, many types of input devices are available for performing operations in computer systems, such as mice, buttons, touch panels, joysticks, touch screens, and the like. And touchscreens are becoming more and more popular due to their ease of use, operational versatility, falling prices, and steadily increasing yields. [0003] The touch screen can be divided into plug-in type and built-in type. The plug-in touch screen can position the panel with touch function in front of the display, and the touch surface covers the visible area of ​​the display area to realize touch control; while the built-in touch screen integrates the touch function in the On the display panel, with or without a protective glass on the outside, users can operate by touching the screen with their fingers. [0004] The...
