DISPLAY DEVICE AND DRIVING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18113602 titled 'DISPLAY DEVICE AND DRIVING METHOD THEREOF
Simplified Explanation
The display device described in the abstract includes a pixel unit with pixel circuits, a scan driver, and a sensing unit. The pixel circuits consist of various transistors and a light emitting element, connected to an initialization power source. The scan driver outputs scan signals and sensing control signals to the pixel circuits through horizontal lines. The sensing unit is responsible for measuring voltages or current at specific nodes within the pixel circuits.

Original Abstract Submitted
A display device for performing a sensing operation according to an embodiment of the present inventive concept includes a pixel unit including pixel circuits each including a light emitting element, a driving transistor, a switching transistor, and a sensing control transistor connected between an anode electrode and an initialization power source; a scan driver connected to the pixel circuits through horizontal lines and sequentially outputting scan signals and sensing control signals; and a sensing unit configured to sense voltages or current of first nodes each disposed between an anode electrode and a driving transistor. The scan driver simultaneously outputs the sensing control signals to the horizontal lines at every predetermined discharge cycle.
