Abstract
The present application discloses a pixel driving chip for compensating an original signal provided to a pixel structure including a driving transistor having a drain electrode coupled to a light-emitting device, the pixel driving chip includes a control circuit configured to generate at least one control voltage signals for controlling the driving transistor; an acquisition circuit configured to acquire a measured source voltage at a source electrode of the driving transistor under control of the at least one control voltage signals; a computation circuit configured to compute a compensation voltage based on the measured source voltage; a storage circuit configured to store the compensation voltage; a compensation circuit configured to compensate the original signal provided to the driving transistor using the compensation voltage stored in the storage circuit to obtain a compensated signal; and an output circuit configured to output the compensated signal to the driving transistor.
