Amoled and micro-oled for augmented reality and autostereoscopic 3d displays

An organic light-emitting diode (OLED) device, comprising:

• a first substrate having a bonding surface;
• a second substrate having a first surface;
• a coloring unit including an OLED layer and optionally a color transformation layer;
• the OLED layer being formed on a selected one of the first and second substrates and the optional color-transformation layer being formed on the second substrate;
• and
• a pixel circuit with pixel driving and controlling functions disposed on the first substrate and coupled to the OLED layer for controlling emission of each sub-pixel of the OLED layer;
• wherein the bonding surface of the first substrate and the first surface of the second substrate are in direct bonding.
