Display using passive matrix organic light emitting diode

A passive matrix organic light emitting diode display which includes a plurality of lower electrode patterns arranged in parallel, a plurality of transparent electrode patterns arranged in parallel in a direction and being perpendicular to the lower electrode pattern, and an organic compound layer interposed between the lower electrode patterns and the lower electrode patterns and the transparent electrode patterns are shared in a control period for each display frame such that display control and image output is done in a display control period and a touch sensor control is done in a touch sensor control period, comprising:

• a multiplexer connected to at least one of the lower electrode pattern and the transparent electrode pattern;
• a display driving circuit connected to the multiplexer and providing a display driving signal for controlling the image output in the display control period;
• a first touch driving circuit connected to the multiplexer and providing a touch driving signal in the touch sensor control period;
• a plurality of mutual electrode patterns provided adjacent to a perimeter of a display area defined by the lower electrode patterns and the transparent electrode patterns and receiving the touch driving signal and providing a touch driven signal in response to a touch on the display area in the touch sensor control period;
• and
• a second touch driving circuit connected to the mutual electrode patterns and receiving the touch driven signal in the touch sensor control period;
• and
• wherein a location of the touch on the display area is sensed through a change in mutual capacitance by using at least one of the mutual electrode patterns as a receiver electrode and using at least one of the lower electrode patterns and the transparent electrode pattern as a transmitter electrode in the touch sensor control period;
• and
• wherein the multiplexer is configured to:
• connect at least one of the lower electrode patterns and the transparent electrode patterns to the display driving circuit in the display control period and connect at least one of the lower electrode patterns and the transparent electrode patterns to the first touch driving circuit in the touch sensor control period.
