Organic light emitting diode display

An organic light emitting diode (OLED) display comprising:

• a plurality of pixels formed on a substrate, wherein each pixel comprises a subpixel of a first color, a subpixel of a second color, and a subpixel of a third color;
• a first resistor comprising
• a resistive material formed on the substrate,
• a first highest reference voltage end, and
• a first lowest reference voltage end;
• a second resistor comprising
• a resistive material formed on the substrate,
• a second highest reference voltage end, and
• a second lowest reference voltage end;
• a third resistor comprising
• a resistive material formed on the substrate,
• a third highest reference voltage end, and
• a third lowest reference voltage end;
• a plurality of first reference voltage output terminals coupled to the first resistor and outputting a plurality of first reference voltages comprising a first highest reference voltage and a first lowest reference voltage;
• a plurality of second reference voltage output terminals coupled to the second resistor and outputting a plurality of second reference voltages comprising a second highest reference voltage and a second lowest reference voltage;
• a plurality of third reference voltage output terminals coupled to the third resistor and outputting a plurality of third reference voltages comprising a third highest reference voltage and a third lowest reference voltage;
• and
• a data driver formed on the substrate, wherein the data driver is configured to:
• convert digital video signals for the first, second, and third subpixels into data voltages based on the first, second, and third reference voltages, respectively, and
• apply the data voltages to the subpixels of first, second, and third colors, respectively.
