Problems solved by technology

However, the traces on the FPC101 used to couple the two parts of the leads will cross with other traces on the FPC101, causing signal interference
In order to reduce interference, it is necessary to increase the number of layers of FPC101, thereby increasing the process complexity and cost of FPC101

Embodiment Construction

[0052] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application. The terms used in the implementation of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0053] Such as Figure 1B As shown, in the prior art, both the specific area Z1 and the specific area Z2 on the corresponding area 1051 on the TFE 105 can be used to provide through holes 1063 for the lead wires 1062, and two parts of the lead wires are respectively drawn out through the through holes 1063 in the two specific areas and It is summarized to TIC1011 through wiring on FPC101. However, the wires on the FPC101 used to couple the two parts of the wires will cross other wires on the FPC101, causing signal interference. In the prior art, in order to reduce the interference caused by crossing wires, it is necessa...

Abstract

The embodiment of the invention provides a touch screen for narrow-bezel electronic equipment and the electronic equipment. The touch screen comprises a conductive layer, a display module, a first circuit board and a second circuit board, wherein the conductive layer comprises a touch sensing electrode and N first leads, and the first circuit board comprises a touch driving integrated circuit; the second circuit board comprises at least one wire; the touch sensing electrode is coupled with the first end of each first lead in the N first leads, the second end of each first lead in the M first leads is coupled with the first end of one wire of the second circuit board through the display module, the second end of each wire in the second circuit board is coupled with the touch driving integrated circuit, and M is smaller than or equal to N; and at least one wire of the second circuit board is used for coupling the second end of each first lead in the M first leads to the touch driving integrated circuit. The touch screen provided by the embodiment of the invention can reduce the process difficulty and cost.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a touch screen and electronic equipment used for narrow-frame electronic equipment. Background technique [0002] With the continuous development of functions of electronic devices, touch screens are more and more widely used in electronic devices such as mobile phones and tablets. A touchscreen is capable of detecting a user's finger or other object placed on its surface and is able to recognize where the finger or object is placed. [0003] Currently, a conductive layer (conductive layer, CL) 106 on the touch screen is used to detect touch operations. Such as Figure 1A As shown, the touch screen may include a flexible printed circuit (flexible printed circuit, FPC) 101, a substrate (substrate, SUB) 104, a display layer (display layer) 103, a thin film encapsulation layer (thinfilm encapsulation layer, TFE) 105 and a conductive layer 106. The conductive lay...
