ORGANIC LIGHT-EMITTING DIODE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18165502 titled 'ORGANIC LIGHT-EMITTING DIODE DISPLAY DEVICE
Simplified Explanation
The abstract describes an organic light-emitting display device that consists of two thin-film transistors (TFTs) placed on a substrate. The first TFT includes a semiconductor layer, a conductive layer overlapping the semiconductor layer, and an insulating layer between them. The second TFT comprises a semiconductor layer and a conductive layer overlapping it. The first semiconductor layer is positioned higher than the second semiconductor layer, with the first layer being made of an oxide semiconductor and the second layer being low temperature polycrystalline silicon (LTPS). The first insulating layer covers the entire first semiconductor layer.

Original Abstract Submitted
An organic light-emitting display device comprises a first thin-film transistor disposed on a substrate; and a second thin-film transistor disposed on the substrate and spaced apart from the first thin-film transistor. The first thin-film transistor comprises a first semiconductor layer, a first conductive layer disposed on the first semiconductor layer and that overlaps the first semiconductor layer, and a first insulating layer disposed between the first semiconductor layer and the first conductive layer. The second thin-film transistor comprises a second semiconductor layer, and a second conductive layer disposed on the second semiconductor layer and that overlaps the second semiconductor layer. The first semiconductor layer is disposed on a layer higher than the second semiconductor layer, the first semiconductor layer comprises an oxide semiconductor, the second semiconductor layer comprises low temperature polycrystalline silicon (LTPS), and the first insulating layer covers the entire first semiconductor layer.
