Abstract: Disclosed are a display substrate, a preparation method therefor, and a display device. The display substrate includes a display region and a binding region on one side of the display region. The binding region includes a binding structure layer disposed on a base. The binding structure layer includes a composite insulating layer disposed on the base. The binding region further includes a step structure formed by the base and the composite insulating layer. Heights of steps in the step structure decrease sequentially in the direction away from the display region. In the step structure, the base forms a first step having the smallest height. The binding structure layer further includes a signal connection wire having at least a portion thereof the disposed on the step structure and located on the first step. An opening exposing the signal connection wire is provided on the base at the first step.

Abstract: A touch circuit includes a touch circuit, a first energy storage circuit, a second energy storage circuit and a resetting circuit. A first end of the first energy storage circuit is connected to a control end of the touch circuit, and a second end thereof is connected to a first voltage input end. A first end of the second energy storage circuit is connected to a first conductive line, and a second end thereof is connected to the control end of the touch circuit. A first end of the touch circuit is connected to the first conductive line, and a second end thereof is connected to a third conductive line. A control end of the resetting circuit is connected to a second conductive line, a first end thereof is connected to the third conductive line, and a second end thereof is connected to a second voltage input end.
