[0047] Figure 6 It is a schematic structural diagram of the bendable part of the touch substrate according to the second embodiment of the present invention. like Figure 6 As shown, this embodiment is an extension of the aforementioned first embodiment. The main structure of the touch substrate of this embodiment is basically the same as that of the aforementioned first embodiment. The difference is that the flexible touch substrate of this embodiment The touch electrodes 15 in the folding portion 13 are self-capacitive touch electrodes. The touch electrode 15 includes a first sub-touch electrode 151 and a second sub-touch electrode 152 that are oppositely arranged. In the second direction, a plurality of first sub-touch electrodes 151 and rows arranged at intervals The lengths of the plurality of second sub-touch electrodes 152 arranged at intervals in a row gradually change, so as to ensure that when the human body touches the touch electrodes 15 , the sensing value of t...

[0050] Figure 7 It is a schematic structural diagram of the bendable part of the touch substrate according to the third embodiment of the present invention. like Figure 7 As shown, this embodiment is an extension of the aforementioned first embodiment. The main structure of the touch substrate of this embodiment is basically the same as that of the aforementioned first embodiment. The difference is that the flexible touch substrate of this embodiment The touch electrodes 15 in the folding portion 13 are self-capacitive touch electrodes. The touch electrode 15 includes a first sub-touch electrode 151 and a second sub-touch electrode 152 oppositely disposed. The first sub-touch electrodes 151 and the second sub-touch electrodes 152 are linear strips. In the first direction, the width of the first sub-touch electrodes 151 gradually decreases, and the width of the second sub-touch electrodes 152 gradually increases.

Abstract

The embodiment of the invention provides a touch substrate and a display device. The touch substrate comprises a substrate body and touch electrodes, wherein the substrate body comprises a plurality of non-bendable parts and at least one bendable part, and the bendable parts are connected between the adjacent non-bendable parts; the touch electrode is arranged on the bendable part, the touch electrode is in a straight line shape, the touch electrode is arranged in the first direction, and the first direction is parallel to the bending axis of the bendable part; therefore, the bending resistance of the touch electrode of the bendable part is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch substrate and a display device. Background technique [0002] Organic Electroluminescent Display (OLED) is one of the hot spots in the field of flat panel display research today. Compared with liquid crystal displays, OLED has low power consumption, high color saturation, wide viewing angle, thin thickness, fast response speed and It can achieve excellent performance such as flexibility. Currently, in the display fields of mobile phones, tablet computers, and digital cameras, OLEDs have begun to replace traditional liquid crystal displays. [0003] The folding display device is the trend of future development, and the folding display device is more convenient to use. However, after the foldable display device is bent multiple times, the touch electrodes in the bendable part will break, and then there will be no touch or touch failure.
