Abstract:
A noise-removing circuit includes a first capacitor to charge a first voltage supplied to a first node during a first period in which a first switching control signal is supplied, a second capacitor to charge a second voltage supplied to a third node during the first period, a third capacitor to charge the first voltage during a second period in which a second switching control signal is supplied, and to charge the second voltage charged in the second capacitor as a third voltage during a third period in which a third switching control signal is supplied, a fourth capacitor to charge the second voltage during the second period, and to charge the first voltage charged in the first capacitor as a fourth voltage during the third period, and a differential amplifier to output a voltage difference between the third voltage and the fourth voltage.
Abstract:
An organic light emitting diode display including a display including data lines, scan lines, sense lines, and pixels electrically coupled to the data, scan, and sense lines, a compensator for sensing first and second driving currents flowing to the pixels corresponding to first and second test data in a compensation mode, to compare first and second reference currents with the first and second driving currents, respectively, and to update compensation data, a signal controller for compensating input data according to the compensation data to generate image data, and for changing the input data into the first and second test data in the compensation mode; and a data driver for generating a plurality of data signals by using one of the image data, the first and second test data, and to supply the data signals to the data lines.
