Touch panel and method for forming touch panel

Abstract

The invention discloses a touch panel and a method for forming the touch panel. The touch panel comprises an adhesive film and a protection glass. A sensing unit of a sensing circuit, a first guide line coupled with the sensing circuit and a second guide line coupled between the first guide line and a processor are formed on the adhesive film. The adhesive film is attached below the protection glass in an attaching manner. Therefore, by the aid of the touch panel and the method, the touch panel can be quick and convenient in processing, poor connection of the first guide line and the second guide line can be avoided, precise positioning is not required, disconnection of the first guide line and the second guide line is not caused, and the touch panel is easier in processing.

Description

technical field [0001] The present invention relates to a touch panel and a method for forming a touch panel, in particular to a touch panel in which a sensing circuit of the touch panel and wires coupled to the sensing circuit and a processor are formed on an adhesive film. Panel and method of forming a touch panel. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram illustrating the touch panel 100 in the prior art. Such as figure 1 As shown, the silver paste is generally laid on the protective glass (such as a transparent cover plate such as glass) 102 by sputtering or printing to form a sensing circuit (including a plurality of sensing units) 104 or to couple sensing circuits. Area wire 106. Then, the flexible printed circuit board (Flexible Printed Circuit, FPC) 112 provided with the processor 108 and the wire 110 coupled to the processor 108 is arranged by pressing, so that the wire 110 coupled to the processor 108 and the w...

Problems solved by technology

[0003] However, the prior art has the following disadvantages: first, the protective glass 102 and the flexible circuit board 112 need to be processed separately, and the pressing between the protective glass 102 and the flexible circuit board 112 consumes manpower and cost; During the pressing process of the glass 102 and the flexible circuit board 112, very precise alignment is required to ensure the bonding of the wire 106 and the wire 110

However, since the line width of the wire 106 and the wire 110 is very narrow, it is difficult for the wire 106 and the wire 110 to align; thirdly, during the pressing process of the protective glass 102 and the flexible circuit board 112, the pressure during the pressing process It may cause the wire 106 and the wire 110 to break; fourth, in order to join the conductive glass on the protective glass 102, the silver paste and the copper on the flexible circuit board 112, the process steps become more complicated; When the wire 106 is made by sputtering, etc., if there is ink on the surface of the protective glass 102, the protective glass 102 will not be easily sputtered.

[0004] Therefore, for manufacturing the touch panel 100, the prior art is not a good manufacturing method
