Abstract

The invention provides a processing method of a conductive layer for a touch sensing film. The wavelength range of laser is selected according to the material of the base material layer; the energy density of the laser is set to be greater than the etching threshold value of the conductive layer; and after passing through the base material layer, the laser beam is reduced to be less than the etching threshold value of the conductive layer, so that the conductive layer on the other side of the base material layer is prevented from being damaged when the electrode pattern is formed in the conductive layer on one side by using the laser beam, and the method has the characteristics of low cost and simple process.

Description

technical field [0001] The invention relates to a manufacturing method of a touch sensor, in particular to a touch sensitive film and a processing method, device and application thereof. Background technique [0002] Capacitive touch screen technology has been widely used in electronic devices such as mobile phones, tablet computers, personal electronic assistants, handheld game consoles, satellite navigation systems and other user interface control panels. [0003] In electronic devices including capacitive touch screens, an XY array of sensing electrodes is formed in a layer of transparent conductive material. In use, a capacitance is formed between the user's finger and the projected capacitance from the sensing electrodes. When a touch is made, it is converted to execute some pre-designed instructions by the underlying electronics and software applications to precisely measure where the user's finger touches. Such panels respond accurately to fingers and stylus. [00...
