Display Device Including Oxide Semiconductor - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240178209 titled 'Display Device Including Oxide Semiconductor
Simplified Explanation
The patent application describes a display device with an oxide semiconductor, including a light-emitting device and a pixel driving circuit in each pixel area. The pixel driving circuit supplies a driving current to the light-emitting device based on a data signal and gate signal. The driving thin-film transistor in the pixel driving circuit is made of an oxide semiconductor and includes at least one switching thin-film transistor. A conductive pattern with a metal is located under the driving semiconductor pattern, having a larger work function than the driving semiconductor pattern to prevent mura at low grayscale without reducing on-current, improving image quality.
