DRIVE CIRCUIT AND DRIVE METHOD OF LIGHT EMITTING DISPLAY APPARATUS
摘要:
A drive circuit for a light emitting display apparatus including a pixel circuit having a light emitting device for emitting a light having brightness determined based on supplied current and a drive transistor for supplying the current to the light emitting device, comprises a threshold value correction circuit converting a second signal including a threshold voltage of the drive transistor and a data voltage, the second signal being output from the drive transistor when a first signal including the data voltage is input into the control electrode of the drive transistor, into a third signal including the threshold voltage of an inverted polarity and the data voltage or a voltage corresponding to the data voltage, to output the converted third signal to the pixel circuit. The pixel circuit includes a switch for supplying the third signal to the control electrode of the drive transistor.
