Organic light emitting display and fabricating method thereof
View Patent ↗A thin organic light emitting device that can be used in thin devices like mobile phones and personal digital assistants. An organic light emitting display (OLED) includes a layer that blocks UV rays so that the diode and the transistor are shielded from UV rays during and after production. In order to prevent breakage during production, two substrates are bonded together and the devices are formed on each of the two substrates, providing a thicker structure that is less apt to break. The substrates are separated after production is complete.
1. An organic light emitting display (OLED), comprising:
a substrate;
an organic light emitting diode, an insulating layer, a gate insulating layer and a semiconductor layer arranged on the substrate, the insulating layer being arranged between the organic light emitting diode and the gate insulating layer, the gate insulating layer being arranged between the insulating layer and the semiconductor layer, the semiconductor layer including a source area, a drain area and a channel area arranged between the source area and the drain area; and
a non-transmissive layer and a gate electrode arranged on the gate insulating layer, wherein the non-transmissive layer and the gate electrode are adapted to block UV-rays, the non-transmissive layer and the gate electrode extending across all of an area of the OLED except at a portion corresponding to contacts to the source area and the drain area of the semiconductor layer, wherein the substrate is of a thickness between 0.05 mm and 1 mm.
2. An organic light emitting display (OLED), comprising:
a substrate;
an organic light emitting diode, an insulating layer, a gate insulating layer and a semiconductor layer arranged on the substrate, the insulating layer being arranged between the organic light emitting diode and the gate insulating layer, the gate insulating layer being arranged between the insulating layer and the semiconductor layer; and
a non-transmissive layer and a gate electrode arranged on the gate insulating layer, wherein the non-transmissive layer and the gate electrode are adapted to block UV-rays, the non-transmissive layer and the gate electrode being on a same level and being comprised of a same material, the non-transmissive layer and the gate electrode extends across substantially all of an area of the OLED.
3. The OLED of claim 2 , the friction-preventing layer having a thickness of 10 to 100 μm.
4. The OLED of claim 2 , the friction-preventing layer being arranged on an opposite side of the substrate from the organic light emitting diode, the insulating layer, the gate insulating layer and the semiconductor layer.
5. The OLED of claim 2 , the organic light emitting diode, the insulating layer, the gate insulating layer and the semiconductor layer being arranged on top of the substrate.
