US Patent 11562699 Display device and method for driving the same

A display device according to an embodiment of the present disclosure includes a light-emitting element configured to emit light, a driving transistor configured to provide a high-level voltage to the light-emitting element, and a switching transistor configured to transfer a voltage input through a data line to a gate node of the driving transistor. The driving transistor operates in a saturation mode in which a voltage of a source node is saturated in response to a first data voltage input to the gate node, and operates in a switch mode in which the driving transistor operates as a switch in response to a second data voltage higher than the first data voltage, so that a driving current generated in the driving transistor is able to be sensed through the source node.
