Abstract: A touch control substrate, a touch control panel, a display substrate, a display panel and a display device are provided in the application. The touch control substrate includes a touch region and a frame wiring region. A plurality of electrode lines in the frame wiring region are distributed in different layers, and orthogonal projections, on a projection plane, of the plurality of electrode lines distributed in the different layers are overlapped, the projection plane being a plane parallel to the touch control substrate.

Abstract: The present disclosure provides a capacitive touch screen and a bending judgment method therefor, and a display device. The touch screen includes: a substrate; touch sensing electrodes and touch drive electrodes located on the substrate; and a touch chip electrically connected with the touch sensing electrodes and touch drive electrodes, and configured to apply a driving signal to the touch drive electrodes, detect a capacitance value of each touch sensing electrode, and when the capacitance values of a part of the touch sensing electrodes adjacent to each other, the number of which is equal to or greater than a preset number, are changed, and a difference in capacitance value between the touch sensing electrodes with changed capacitance values is less than a predetermined value, to determine a bending state of the touch screen based on capacitance value change information of the touch sensing electrodes with changed capacitance values.
