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.
