Patent ID: 8624801

Claim:
A display device comprising: a pixel structure comprising: a first transistor having a gate, a drain, and a source; circuitry to: initially set the first transistor gate at a first voltage, in response to a data signal received over a data line of the display device, set the first transistor gate at a second voltage, transition the first transistor gate voltage from the second voltage to a third voltage that is higher than the second voltage by a reference voltage; and a light element coupled to the first transistor and configured to emit light in response to a current through the light element, wherein the circuitry further comprises: a second transistor for inputting a first source voltage to the source of the first transistor according to a power switch signal; and a third transistor for inputting the data signal directly to a terminal where the first transistor is serially connected with the second transistor or a terminal where the first transistor is serially connected with the light element a fourth transistor, comprising a first terminal, a second terminal and a control terminal, the first terminal connected to the gate of the first transistor, the second terminal directly connected to the drain of the first transistor and the control terminal of the fourth transistor being used for receiving a reset signal, wherein the first transistor is associated with a threshold voltage, and wherein the second voltage is equal to a voltage of the data signal less the threshold voltage, and the first voltage is a preset voltage less than the second voltage.
