Problems solved by technology

[0002] Modern mobile phone design generally requires that the width of the TP black frame be as narrow as possible, but the traditional TP design will reduce the effective contact area between the TP and the front case, which will cause the TP to be easily separated from the front case or even fall off; and the traditional TP design The adhesive method used in the TP design also makes it difficult to disassemble the TP made

Embodiment 1

[0022] A touch-sensitive device for a mobile phone, comprising a touch screen outer panel 1, an FPC sensing circuit board 2 and a mobile phone main board 3 stacked sequentially from top to bottom, the FPC sensing circuit board 2 is electrically connected to the mobile phone main board 3, the The mobile phone main board 3 is provided with a touch screen chip 4 electrically connected to the FPC sensing circuit board 2, and the FPC sensing circuit board 2 and the mobile phone main board 3 are mutually movable and clamped;

[0023] The touch screen outer panel 1 includes a top ITO board and OCA optical glue. The top ITO board is the cover of the touch-sensitive device, the contact surface touched by the user, and also the upper circuit part of the touch screen. It is printed by silver paste and ITO Etching combined wiring, the OCA optical glue is used to bond the top ITO board and FPC sensing circuit board.

Abstract

The invention relates to touch sensitive equipment for a mobile phone. A touch screen outside panel is fixedly connected with an FPC sensing circuit board; the FPC sensing circuit board is movably and detachably connected with a mainboard of the mobile phone in a clamping way; during maintenance, the FPC sensing circuit board can be detached from the mainboard of the mobile phone, and a corresponding part is replaced; if the FPC sensing circuit board or the touch screen outside panel is damaged, the FPC sensing circuit board is directly detached, and then a new FPC sensing circuit board and a new touch screen outside panel component are replaced, so that the maintenance work is very simple and convenient, and meanwhile, the maintenance cost is reduced; only a small part of black skirt can be seen from an AA viewing area of an LCD (Liquid Crystal Display), so that an ultra-narrow touch screen black border effect is achieved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch-sensitive device for mobile phones. Background technique [0002] Modern mobile phone design generally requires that the width of the TP black frame be as narrow as possible, but the traditional TP design will reduce the effective contact area between the TP and the front case, which will cause the TP to be easily separated from the front case or even fall off; and the traditional TP design The adhesive method used in the TP design also makes it difficult to disassemble the TP made of glass, and it is very easy to scratch or even damage the TP. [0003] The traditional FPC sensing circuit board 2 and the mobile phone main board 3 are fixedly connected together. When a part needs to be replaced (for example, the FPC sensing circuit board 2 is broken, a new FPC sensing circuit board needs to be replaced. 2) Just have to change whole capacitive touch screen, brought a...
