Abstract
The disclosure provides a stacked OLED device and a method thereof, wherein the device comprises a forward and reverse of a first OLED structure, and a second forward OLED structure stacked from bottom to top on a substrate sequentially; a charge generation layer disposed between the forward and reverse of the first OLED structure as a common cathode, and each organic functional layer in the forward and reverse of the first OLED structure are symmetrical with the charge generation layer; a transparent insulating layer disposed between the first reverse and the second forward OLED structure; an anode of the first and second forward OLED structure are connected through a conductive layer. The disclosure reduces the use of a precision mask so that a space occupied by three primary colors is reduced, greatly increases a pixel resolution, improves a product yield rate, saves the cost, and enhances a product competitiveness.
