Abstract

The invention discloses a capacitive touch screen. The technical problem that the back face touch signals of a conventional capacitive touch screen in the prior art are looked on as interference signals and are either shielded or discarded in the prior art is solved. According to the technical scheme, the capacitive touch screen comprises a substrate, an electrode layer, a flexible circuit board, a front face cover plate, a back face cover plate, front face optical cement and back face optical cement. The electrode layer covers the front face of the substrate, and a connecting part is arranged at the upper end of the electrode layer. The flexible circuit board is inserted into the connecting part on the electrode layer. The front face cover plate covers the electrode layer through the front face optical cement. The back face cover plate covers the back face of the substrate through the back face optical cement. The front face optical cement and the back face optical cement are two different sorts of optical cement. The front face cover plate and the back face cover plate are made of two different sorts of materials.

Description

technical field [0001] The invention relates to a capacitive touch screen, in particular to a capacitive touch screen with double-sided effective touch functions. Background technique [0002] Since the advent of Iphone, its gorgeous appearance, novel operation method and comfortable feel, capacitive touch screen has been recognized by customers, such as mobile phones, media players, navigation systems, digital cameras, digital photo frames, PDAs, game equipment, monitors, electrical appliances It can be seen in various fields of daily life such as control and medical equipment. However, with the popularity of capacitive touch screen applications, under the guidance of personalization and trends, conventional capacitive touch screens do not have many novel features that can attract users' special attention. The reverse touch signal of the conventional capacitive touch screen has been regarded as an interference signal or shielded or abandoned. Contents of the invention ...
