Abstract:
Method of driving a pixel element having a first capacitive element, a first transistor, and a compound-switch that includes at least one switching transistor and at least one secondary switching element. The method includes (1) setting the bias voltage of the first transistor to a value that is substantially close to a threshold voltage of the first transistor at the end of a first time period after starting changing a voltage across the first capacitive element at the beginning of the first time period, and (2) writing a pixel data into the pixel element to change the bias voltage of the first transistor to a target value that is different from the threshold voltage of the first transistor during a second time period while keeping the compound-switch at conducting state. The first time period is at least three times as long as the second time period.
