Problems solved by technology
However, the current flexible touch screen products are not truly flexible touch screens due to many limitations such as load bearings and preparation materials.
On the one hand, most of the existing flexible screens use COP (Chip on Plastic, chip mounted on plastic) or PET (poly (ethylene terephthalate), polyethylene terephthalate) as the flexible substrate, which Large stress will be generated when bending, especially COP materials, which can easily cause cracks in touch electrodes such as ITO (Indium Tin Oxide, indium tin oxide) electrodes due to stress mismatch, so this kind of substrate can only Meet the needs of small curvature bending or fixed curvature bending; on the other hand, due to the limitation of the laminated structure, the existing flexible screen can only achieve bending in a single direction, and cannot achieve double-sided bending

The invention relates to the technical field of display and provides a touch panel, a touch panel preparation method and a display device. The touch panel comprises a first touch substrate and a second touch substrate, and the first touch substrate and the second touch substrate are in opposite arrangement. At least one of the first touch substrate and the second touch substrate comprises a flexible substrate, a plurality of touch electrodes, a plurality of first channels and a plurality of second channels, wherein the touch electrodes are arranged at intervals on the flexible substrate; one side, with the touch electrodes, of the flexible substrate is provided with the first channels among adjacent touch electrodes; one side, without the touch electrodes, of the flexible substrate is provided with the second channels corresponding to the touch electrodes. The touch panel, the touch panel preparation method and the display device have the advantage of improvement of the bending performance of the flexible touch panel.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular to a touch panel, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for electronic products. Today's electronic products not only require intelligence and touch functions, but also meet users' needs for thin, light and portable products. As an indispensable electronic product in daily life, smart phones can more concentratedly reflect the consumption concept of users. [0003] In recent years, the development of flexible technology has become increasingly mature, and flexible touch screens have emerged under this general trend. Flexible touch screen, as the name suggests, is a touch screen that can be bent. Compared with ordinary touch screen products, this kind of touch screen product can realize the bending of fixed curvature, and it can b...
