Abstract

A method of manufacturing a display device having an OLED display and a touch screen, the OLED display including components that are sensitive to high temperatures, and the touch screen including a resistive film, includes the steps of: providing a transparent substrate having two sides; forming a flat-panel organic light emitting diode display on one side of the substrate; forming a resistive film using a low temperature technique on the other side of the substrate; and forming a resistive touch screen on the resistive film.
