Abstract
A dual display device has pixels and each pixel includes a transparent substrate, an active driving circuit, a top organic LED, a bottom organic LED, an insulation layer that covers the active driving circuit and the bottom organic LED, and a contact hole. A connection element covers the insulation layer, the top organic LED is deposited on the connection element, and the anodes of the two LEDs electrically connect to the active driving circuit through the contact hole by the connection element. Hence, each pixel forms a structure that two organic LEDs stack together on the transparent substrate and the top and bottom organic LEDs can be driven respectively so as to achieve the dual display device.
