Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is explained in more detail.

[0027] See Figure 1 to Figure 6 , the present invention discloses a flexible anti-interference projected capacitive touch screen, which includes three layers of high-transmittance optical PET, wherein the upper bottom surface of the upper layer PET 1 is a hard surface 11 that has been hardened to prevent scratches. The hardness of the surface 11 is above Rockwell 3H; both sides of the middle layer PET 2 are provided with ITO, and the ITO 21 on the upper bottom surface of the middle layer PET 2 is etched into an X or Y-axis diamond-shaped ITO pattern and an upper bottom surface interface circuit 27. An upper optical adjustment layer 22 is provided between the upper bottom surface of the middle layer PET2 and the ITO21 on the upper bottom surface, and the ITO on the lower bottom surface of the middle layer PET 2 is etched with a Y or X-axis diamond-shaped ITO pattern and ...

Abstract

The invention relates to a flexible anti-interference projection-type capacitor touch screen which comprises three layers of high-transmittance optical PET, wherein the upper bottom surface of the upper layer of PET is a hard surface which is hardened and prevents from being scraped; two surfaces of the middle layer of PET are both provided with ITO, the ITO on the upper bottom surface is etched to be an X-axle or Y-axle diamond pattern and an upper bottom surface interface line, the ITO on the lower bottom surface is etched to be a Y-axle or X-axle diamond ITO pattern and a lower bottom surface interface line; the upper bottom surface of the bottom layer of PET is provided with integral ITO which is grounded; and the three layers of high-transmittance optical PET are sequentially adhered into an integral body through transparent optical cement. The invention has the advantages of being suitable to a curved surface and a plane and preventing the self-noise signal interference of a mobile phone as well as having low cost.

Description

technical field [0001] The present invention relates to a projected capacitive touch screen, which will be applied to high-end mobile phone products, and will also quickly penetrate into other application fields, such as: PDA, PC, GPS system, household appliances and so on. Background technique [0002] Since Apple released the iPhone projected capacitive touch screen mobile phone in June 2007, it has caused a huge shock in the global mobile phone field, and its sales performance has also achieved great success. In view of the fact that capacitive touch screens have higher light transmittance, resolution, service life, and multi-touch performance than resistive touch screens, not only has changed consumers' habits of using man-machine interface, but also rekindled the enthusiasm of related touch manufacturers. For future business opportunities, major mobile phone manufacturers have announced that they will launch or develop touch-screen mobile phones, and the focus of resear...
