PIXEL CIRCUIT AND DISPLAY APPARATUS COMPRISING PIXEL CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18202064 titled 'PIXEL CIRCUIT AND DISPLAY APPARATUS COMPRISING PIXEL CIRCUIT

Simplified Explanation

The abstract describes a pixel circuit design for display devices.

• The circuit includes a capacitor, transistors, and an emission element.
• The capacitor is connected between two nodes.
• A first transistor connects a data line to one of the nodes.
• A driving transistor has a gate electrode connected to the other node.
• The driving transistor has two electrodes connected to voltage supply lines.
• A second transistor connects the second node to a reference voltage supply line.
• A third transistor connects the reference voltage supply line to another node.
• An emission element is connected to the driving transistor and the third transistor through the other node.
