More Information
Summary:A display system comprises at least one pixel. The pixels include a switching unit and a control unit. The control unit is used to respectively control level of first and second nodes. During a first period, the level of the first node is equal to a first reference level, and the level of the second node is equal to a second reference level. During a second period, the level of the first node is equal to a third reference level, and a voltage difference between the first and second nodes is equal to critical voltage of a drive unit. During a third period, the level of the first node is equal to data signal. During a fourth period, the drive unit lights up a light emitting unit according the voltage difference between the first and second nodes. The display system is capable of compensating influence caused by non-uniformity in mobility of a transistor M3, and also capable of regulating charging speed of a node N within a period st3, namely avoiding excessiveness of delta V.
