Abstract

The invention provides a touch panel which at least comprises a touch-pressure film, an upper conducting film, a lower conducting film and a substrate. The touch panel is mainly characterized in that at least one contact surface of the upper conducting film or the lower conducting film is equipped with a projection structure. In the invention, when a finger or a pen lightly presses the touch panel, the upper conducting film is preferentially contacted with the lower conducting film via the top end of the projection structure and the upper electrode and the lower electrode are conductive with each other, thus enhancing the recognition capability of a system and achieving the efficacies of increasing the edge operable area and enhancing the sensitivity.

Description

【Technical field】 [0001] The present invention relates to a touch panel, in particular to an operation interface that can make the light source highly transparent, so that users can use vision and touch to input conveniently. 【Background technique】 [0002] With the rapid advancement of panel manufacturing technology in recent years, the production cost of touch panels has been greatly reduced. Therefore, touch panels have been widely used in general consumer electronics products, such as mobile phones. Telephones, digital cameras, digital music players (MP3), personal digital assistants (PDA), satellite navigation devices (GPS), and even new UMPC (Ultra Mobile PC) and other small digital appliances, In these electronic products, the touch panel is configured on the display of the electrical appliance, so that the user can perform interactive input operations, thereby greatly improving the friendliness of the communication interface between man and machine, and improving the...
