Problems solved by technology

[0004] Since each electrode needs to be connected to two first terminals, the number of first terminals in the touch structure is too large, resulting in a large area for setting the first terminals in the touch structure, which is not suitable for narrow borders of large-screen devices. design

Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] see figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a touch structure 100 in an implementation manner. The embodiment of the present invention provides a touch structure 100. The touch structure 100 is mainly used in projected capacitive touch screens, especially those with large-scale projected capacitive touch screens. Electronic devices with large screens, such as tablet computers, pers...

Abstract

The invention discloses a touch structure, a touch screen with the touch structure and electronic equipment with the touch structure. The touch structure comprises a plurality of electrodes, a plurality of first leads, a plurality of second leads and a plurality of first terminals, wherein one end of each first lead is connected with the first end of the corresponding electrode, the other end of each first lead is connected with the corresponding first terminal, one end of each second lead is connected with the second end, opposite to the first end, of the corresponding electrode, the other end of each second lead is connected with the corresponding first terminal, and each first terminal is connected with a flexible circuit board. According to the touch structure, the two opposite ends ofeach single electrode are electrically connected to the same first terminal through the first lead and the second lead respectively, so that the number of the first terminals is reduced while the electrodes can be smoothly driven, the area of the area, provided with the first terminals, in the touch structure is reduced, and therefore the narrow frame design requirement of large-screen equipmentis met.

Description

technical field [0001] This field belongs to the field of touch control, and in particular relates to a touch control structure, a touch screen and electronic equipment with the touch control structure. Background technique [0002] With the development of touch technology, capacitive screens that are easy to trigger and respond quickly have gradually occupied the mainstream market, especially projected capacitive screens that can support multi-touch. The projected capacitive screen calculates the position of the finger by detecting the change of the position capacitance when the finger touches it, and performs multi-touch operation. [0003] In the projected capacitive screen, a plurality of electrodes are used for positioning, and the electrodes need to be electrically connected to the first terminal through the lead wire, and then the first terminal is connected to the second terminal of the flexible circuit board, so as to be driven by the power supply of the flexible ci...
