Problems solved by technology

[0004] However, the overall steps of the above scheme are relatively complicated, and the lamination of the film sensor with the ITO pattern and the cover glass requires a large number of lamination support points, resulting in a high scrap rate in the process of manufacturing touch panel products.

Abstract

The invention provides a method for realizing virtual keys on a curved side of a touch panel. The method includes preparing a glass sheet consisting of a flat plate part and at least one side with curved plate part, forming a visible region and an icon region of the touch panel on the inner side,containing the curved plate part, of the glass sheet through silk printing; attaching pattern surfaces of a first flexible circuit board which is provided with at least one side having ITO(indium tin oxid) patterns to the curved part of the inner side of the glass sheet, while making the edges of the planar part of the inner side of the glass sheet disconnected or adjacent with the first flexible circuit board, namely making the first flexible circuit board out of attaching to the planar part of the inner side of the glass sheet. The processing of the method is simple; the first flexible circuit board is of small area, and accordingly is quite flexible to use, and can meet more requirements for shapes if it has enough attachment supporting points. There is no electric connection between the first flexible circuit board and a film sensor, so that the method is not limited by structure limitation in the sensor processing.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a method for realizing a virtual key on a curved side of a touch panel. Background technique [0002] Touch panels are widely used in the field of mobile phones, but now the ICON area where the virtual buttons are located is concentrated in the front of the panel. Curved glass panels are gradually being used in mobile phones, but the side buttons are still dominated by physical buttons. Those skilled in the art know that it is theoretically feasible to use virtual buttons for other buttons except the power button. irreplaceable. Traditional keys such as volume keys and camera shortcut keys are also physical keys. For example, designing virtual keys directly on the side of the panel as volume keys or designing virtual keys as shortcut keys for taking pictures can save assembly processes and avoid physical buttons being pressed many times. problems causing failure. [0003] In t...
