More Information
Summary:A PMOLED display disclosed in the invention includes a plurality of lower electrode patterns arranged in parallel in the x-axis direction, a plurality of transparent electrode patterns arranged in parallel in the y-axis direction and being perpendicular to the lower electrode patterns, and an organic compound layer interposed between the lower electrode patterns and the transparent electrode patterns. A display output and a touch sensing is performed by time-sharing a control period for the lower electrode patterns and the transparent electrode patterns into a display control period and a touch-sensor control period in every display frame time. The PMOLED display includes a driving node formed on a line for communication between the transparent electrode patterns and a display driving circuit, a touch-sensing unit connecting the driving node and a touch-sensing circuit; and a plurality of metal electrode patterns provided between the transparent electrode patterns to have a length shorter than the transparent
