Abstract: A touchscreen includes a touch drive electrode, a touch sensing electrode, a touch drive circuit, a gate drive circuit, a touch drive electrode lead, and a liquid crystal panel. The touch drive electrode extends along a first direction. The touch drive circuit is disposed in a non-display area of the touchscreen, and an extension direction of the touch drive circuit is parallel to an extension direction of the touch drive electrode. The extension direction of the touch drive circuit is the same as the extension direction of the touch drive electrode. Each touch drive electrode is connected to the touch drive circuit using a touch drive electrode lead. The touch drive electrode lead is disposed in an area in which a gate drive circuit is located. The touch drive electrode lead and the gate drive circuit are disposed in an overlapping manner and are isolated from each other.

Abstract: This application provides a touch display panel, a flexible display apparatus, and a method for manufacturing the touch display panel. The touch display panel includes a flexible substrate, a display component, a touch component, and a thin film encapsulation layer. The touch component and the display component are located at different locations on an upper surface of the flexible substrate, and the touch component and the display component are stacked together through folding, to form the touch display panel. The thin film encapsulation layer is formed on an upper surface of the touch component, an upper surface of the display component, and the upper surface of the flexible substrate. Due to a bendable feature of the flexible substrate, the display component and the touch component are manufactured at different locations on the flexible substrate at the same time, and an integrated touch display panel is formed through folding. In this way, a procedure of separately manufacturing the touch component is saved, and corresponding manufacturing costs are reduced. In addition, because the touch component and the display component are interconnected by using an internal circuit, a procedure of electrically connecting the touch component to the display component during assembly is saved. This shortens a manufacturing procedure and reduces costs of the touch display panel.
