Amoled double-side display

An active matrix organic light-emitting diode (AMOLED) doubled-sided display, which comprises:

• a substrate, and an OLED array layer disposed on the substrate;
• the OLED array layer comprising a plurality of top-emitting OLED units and a plurality of bottom-emitting OLED units arranged in an array, wherein the top emitting OLED units and the bottom-emitting OLED units being arranged alternatingly in at least one of the horizontal direction or vertical direction;
• the top-emitting OLED unit and the bottom-emitting OLED unit both comprising an anode, an organic layer and a cathode from the bottom up in a stack structure;
• the anode of the top-emitting OLED unit and the anode of the bottom-emitting OLED unit being the first anode and the second anode respectively, the first anode being thicker than the second anode, the first anode being reflective and the second cathode being light-transm issive;
• the cathode of the top-emitting OLED unit and the cathode of the bottom-emitting OLED unit being the first cathode and the second cathode respectively, the second cathode being thicker than the first cathode, the first cathode being light-transmissive and the second cathode being reflective;
• wherein the first anode and the second anode being formed respectively by two vacuum evaporation processes with mask;
• wherein the OLED array layer comprising a first cathode film and a second cathode film, and the second cathode film being formed on an upper surface of the first cathode film corresponding to the plurality of bottom-emitting OLED units by a vacuum evaporation process with a mask;
• the first cathode being formed by a part of the first cathode film corresponding to the top-emitting OLED unit, and the second cathode being formed by a part of the first cathode film and the second cathode film corresponding to the bottom-emitting OLED unit.
