OLED TOUCH PANEL AND METHOD OF FORMING THE SAME

摘要

A displaying region and a sensing region are defined in each pixel region of the OLED touch panel of the present invention. The readout thin film transistor of the sensing region is formed by the same processes with the drive thin film transistor of the displaying region. The top and bottom electrodes of the optical sensor are formed by the same processes with the top and bottom electrodes of the OLED. Accordingly, the present invention can just add a step of forming the patterned sensing dielectric layer to the processes of forming an OLED panel to integrate the optical sensor into the pixel region of the OLED panel. Thus, an OLED touch panel is formed.
