Abstract

The invention discloses an FPC touch screen. The FPC touch screen comprises a surface protective film, a silver paste layer, an FPC, a bottom surface protective film and a main circuit completing the touch screen function, wherein the surface protective film, the silver paste layer, the FPC and the bottom surface protective film are sequentially arranged in an overlap mode, the silver paste layer is connected with the FPC through a lead, the FPC is connected with the main circuit through a lead, the silver paste layer comprises a key area, a grounded area and an insulation area, and an isolation area is arranged between the key area and the grounded area. According to the FPC touch screen, light transmitting performance of the FPC touch screen is greatly improved, meanwhile, sensitivity and anti-interference ability are enhanced, the FPC touch screen can be curved and folded, and the design requirement for different keys is met. In addition, the FPC touch screen prevents moisture and dust, is slightly affected by temperature changes, is easy to install, and not prone to abrasion, and meets the requirement for the structural types of the various keys and appearance design of products.

Description

[0001] technical field [0002] The invention relates to a touch screen, in particular to an FPC touch screen. Background technique [0003] FPC, "Flexible Printed Circuit", also known as flexible circuit board, referred to as soft board, is a highly reliable and excellent flexible printed circuit made of polyimide or polyester film as the base material. The board has the characteristics of high wiring density, light weight, and thin thickness. It is mainly used in many products such as mobile phones, notebook computers, PDAs, digital cameras, and LCMs. Compared with PCB (Printed Circuit Board), that is, printed circuit board, FPC has the advantages of shorter assembly time, smaller volume than PCB, lighter weight than PCB, and thinner thickness than PCB. It can save redundant cables in the installation of electronic products. The connection work can effectively reduce the volume of electronic products and increase the convenience of carrying them. At the same time, it ...
