DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240196666 titled 'DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME
The abstract describes a display panel that reduces mura at low grayscale by increasing the thickness of the gate insulating layer of a driving thin-film transistor and reducing its mobility to decrease the k-factor. The panel includes sub-pixels with driving thin-film transistors, switching thin-film transistors, and storage capacitors on a substrate, with the driving thin-film transistor featuring a dehydrogenated semiconductor layer.
- The display panel reduces mura at low grayscale by modifying the driving thin-film transistor.
- Increasing the gate insulating layer thickness and reducing mobility lowers the k-factor.
- Sub-pixels contain driving thin-film transistors, switching thin-film transistors, and storage capacitors.
- The driving thin-film transistor includes a dehydrogenated semiconductor layer for improved performance.
