Abstract
The present invention discloses an OLED display having a first row of light emitting diodes and a second row of light emitting diodes. A first sensor circuit is coupled to a light emitting diode of the first linear array for detecting an output of the light emitting diode of the first linear array. A second sensor circuit is coupled to a light emitting diode of the second linear array for detecting an output of the light emitting diode of the second linear array. A control circuit simultaneously causes the light emitting diode of the first linear array to emit light and the sensor circuit coupled to the light emitting diode of the second linear array to provide information corresponding to the detected output of the light emitting diode of the second linear array to a sensor reader circuit.
