Abstract: An electronic device and a method for manufacturing the display apparatus. The electronic device includes a display apparatus and a processor, wherein the display apparatus includes an active-matrix organic light emitting diode (AMOLED) panel, a touch panel, a chip IC, and a printed circuit board. The touch panel is disposed on an upper surface of the AMOLED panel, and the touch panel and the AMOLED panel each has an outgoing line. The outgoing line of the touch panel and the outgoing line of the AMOLED panel are separately extended to form an outgoing line extension end of the touch panel and an outgoing line extension end of the AMOLED panel. The outgoing line extension end of the AMOLED panel and the outgoing line extension end of the touch panel are electrically connected to the printed circuit board PCB by using the chip IC.

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.
