摘要： A data driver used in a current-driving display device for receiving a digital signal and for outputting a gray-scaled current signal to a data line. The data driver includes a digital-to-analog current converter for transforming the digital signal into an analog current signal, a current-copying/reproducing module, and a control circuit. The current-copying/reproducing module is used to store a predetermined voltage for conducting the analog current signal in a transforming/storing status and to conduct a reproducing current signal to the data line in a reproducing/sustaining status. The control circuit is electrically connected between the digital-to-analog current converter and the current-copying/reproducing module for providing a switch between the transforming/storing status and the reproducing/sustaining status. The reproducing current signal is the gray-scaled current signal and is almost equivalent to the analog current signal.

摘要： An organic light emitting diode (OLED) display includes a first and a second digital/analog current converters, a feedback unit and a compensating unit. The feedback unit includes the first and second feedback circuits for generating the first and second feedback currents, respectively. The compensating unit includes the first and second compensating circuits for outputting the first and second compensating voltages as the first and second reference voltages for the first and second digital/analog current converters in accordance with the first and second feedback currents, respectively. The luminance change of the first and second pixels is positively proportional to the first and second feedback current change. Therefore, the first and second compensating voltages are changed accordingly, and the first and second reference voltages are regulated so as to compensate for the luminance of the first and second pixels.
