PIXEL AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18457897 titled 'PIXEL AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The patent application describes a pixel structure that includes multiple transistors and capacitors to control the current flowing through a light-emitting element. The pixel is designed to provide a sweep voltage that linearly changes from one voltage level to another and then nonlinearly changes to a third voltage level when a specific transistor is activated.
- First transistor generates current from a power source line to a light-emitting element.
- Second transistor controls the gate electrode of the first transistor.
- Third transistor controls the gate electrode of the second transistor and is activated by a first signal.
- Fourth transistor controls a first node and is activated by a second signal.
- First capacitor is between the gate electrode of the first transistor and the first node.
- Second capacitor is between the gate electrode of the second transistor and a sweep voltage line.
