Abstract
The embodiment of the invention provides a touch panel, a preparation method thereof and a touch device. The touch panel comprises a display area and a non-display area located on the periphery of the display area. The first black matrix layer is located in the non-display area and arranged on one side of the substrate, and the first black matrix layer comprises hollowed-out areas arranged at intervals and a first black matrix layer main body structure located outside the hollowed-out areas; the first electrodes extend in the first direction, the first electrodes located in the non-display area comprise first sub-electrodes, and the first sub-electrodes are arranged on one side of the part, exposed out of the hollowed-out area, of the substrate; and a plurality of first dummy electrodes extending in the first direction are disposed between two adjacent first electrodes. According to the embodiment of the invention, the first sub-electrode is arranged in the hollow area corresponding to the first black matrix layer, so that the first black matrix layer is prevented from being punctured by generated static electricity, and short circuit caused by connection of the first electrode and the first dummy electrode is avoided, so that failure of a touch function of the touch panel caused by the short circuit is avoided.
Description
technical field [0001] The present application relates to the field of touch technology, and in particular, the present application relates to a touch panel, a preparation method thereof, and a touch device. Background technique [0002] A single-piece touch panel is a touch panel obtained by sequentially forming a black matrix layer and an indium tin oxide pattern on a base substrate (usually a protective glass). The ITO pattern in the current monolithic touch panel includes a plurality of first electrodes (eg, sensing electrodes) arranged laterally and a plurality of second electrodes (eg, driving electrodes) arranged vertically. [0003] However, the first electrode or the second electrode and the corresponding dummy electrode are likely to be short-circuited, which eventually causes the touch function of the touch panel to fail. SUMMARY OF THE INVENTION [0004] In view of the shortcomings of the prior art, the present application proposes a touch panel, a method for ...
