Abstract
A driving control circuit with a compensating circuit detects pixel driving circuits in a display apparatus for compensating a threshold voltage in the pixel driving circuits. The compensating circuit electrically connects with the pixel driving circuits through a corresponding monitoring line. The pixel driving circuit sequentially operates during a detecting time period and a displaying period. Each pixel driving circuit comprises a driving transistor and an OLED. During the detecting time period, the compensating circuit charges a node in each pixel driving circuit by a constant current for speeding up a time of the detecting time period. The node is connected between a terminal of the driving transistor and the OLED in each pixel driving circuit.
