The invention discloses a touch panel, comprising a first transparent substrate, a first conductive pattern, first electrodes, a second transparent substrate, a second conductive pattern, second electrodes and a spacer. The first conductive pattern is configured on the first transparent substrate and extended along a first direction; the first electrodes are respectively configured at two ends ofeach first conductive pattern in the first direction; the second conductive pattern is configured on the second transparent substrate and extended along a second direction; the first direction intersects with the second direction; and the second electrodes are respectively configured at two ends of the each second conductive pattern in the second direction. The conductive patterns are positioned between the two transparent substrates; the projections of the conductive patterns on the first transparent substrate partially overlap so as to form a plurality of sensing zones; and the spacer is configured between the first conductive pattern and the second conductive pattern to form a clearance.
Description
Touch panel and driving method thereof technical field The present invention relates to a touch panel and its driving method, and in particular to a resistive touch panel and its driving method. Background technique In recent years, all kinds of electronic products are constantly moving towards the direction of easy operation, small size and large screen size, especially portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch panel and the liquid crystal display panel, so as to omit the space required for the keyboard or the control keys, thereby expanding the configurable area of the screen. Currently, touch panels can be roughly classified into resistive, capacitive, infrared and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. As far as the capacitive touch panel is concerned, the multi-touch feature provides a more ...
