PIXEL, DISPLAY DEVICE, AND DRIVING METHOD OF THE DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240096265 titled 'PIXEL, DISPLAY DEVICE, AND DRIVING METHOD OF THE DISPLAY DEVICE

Simplified Explanation

The abstract describes a pixel structure that includes a first transistor, a first emission control transistor, and a second emission control transistor. The timing of the on-off states of these transistors is controlled by specific signals, creating a time interval between the activation of the first and second emission control signals.

• The pixel structure includes:

   - A first transistor with a gate electrode connected to a first node, a second node for the power voltage, and a third node connected to the light emitting element.
   - A first emission control transistor with timing controlled by a first emission control signal.
   - A second emission control transistor with timing controlled by a second emission control signal.

• A time interval is present between the activation of the first and second emission control signals, causing a drop in voltage at the second node.

Original Abstract Submitted

a pixel includes: a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is applied, and a third node electrically connected to the light emitting element; a first emission control transistor having an on-off timing controlled by a first emission control signal; and a second emission control transistor having an on-off timing controlled by a second emission control signal. a time interval exists between a time at which the first emission control signal having a turn-on level is input such that a voltage of the second node is dropped from a bias voltage having a voltage level higher than a voltage level of the first power voltage and a time at which the second emission control signal having a turn-on level is input.
