Abstract: A display, a pixel circuitry and an operating method of the pixel circuitry are provided. The display includes a source driver and a pixel circuitry. The source driver converts a first pixel data to a first polarity data voltage and a second polarity data voltage during a first frame period and converts a second pixel data to a third polarity data voltage and a fourth polarity data voltage during a second frame period. The pixel circuitry is coupled to the source driver. The pixel circuitry stores the first polarity data voltage and the second polarity data voltage during the first frame period, displays the first polarity data voltage and the second polarity data voltage during a first sub-period and a second sub-period of the second frame period respectively, and stores the third polarity data voltage and the fourth polarity data voltage during the second frame period.

Abstract: A current-type driver of light emitting devices is provided. The current-type driver includes a power conversion circuit, a feedback module, and a control module. The power conversion circuit modulates and generates an output voltage according to a feedback signal so as to sequentially drive a plurality of light emitting devices. The feedback module generates the feedback signal for the power conversion circuit according to the output voltage and an adjusting signal during a first period, wherein none of the light emitting devices is driven during the first period. The control module outputs the adjusting signal to the feedback module during the first period so as to allow the power conversion circuit to adjust the output voltage to a pre-drive voltage corresponding to the light emitting device which is to be driven next among the light emitting devices.
