PIXEL AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240135868 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 includes a first transistor that generates current from a power source line to a second power source line through a light-emitting element.
• A second transistor controls the gate electrode of the first transistor, while a third transistor is controlled by a first signal to regulate the current flow.
• A fourth transistor is controlled by a second signal and is connected to a first node, along with a first capacitor.
• A second capacitor is connected to the gate electrode of the second transistor and a sweep voltage line that provides a sweep voltage changing linearly and nonlinearly.

Original Abstract Submitted

a pixel includes a first transistor generating current from a first power source line to a second power source line through a light-emitting element, a second transistor between a third power source line and a gate electrode of the first transistor, a third transistor between a data line and a gate electrode of the second transistor and controlled by a first signal, a fourth transistor between a fourth power source line and a first node and controlled by a second signal, a first capacitor between the gate electrode of the first transistor and the first node, and a second capacitor between the gate electrode of the second transistor and a sweep voltage line providing a sweep voltage that linearly changes from a first voltage level to a second voltage level, and nonlinearly changes from the second voltage level to a third voltage level when the third transistor is on.
