A PMOLED display 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 electrode patterns.

Passive matrix organic light emitting diode display

Provided is a method of sensing an illuminance in a passive matrix organic light emitting diode display, the display including a plurality of lower electrode patterns arranged in parallel, a plurality of transparent electrode patterns arranged in parallel and being perpendicular to the lower electrode patterns, and an organic compound layer interposed between the lower electrode pattern and the transparent electrode pattern, the method comprising steps of: (a) forming a predetermined voltage difference between at least one electrode patterns of the transparent electrode patterns as anodes and the lower electrode patterns as cathodes; (b) measuring the magnitude of current formed by the transparent electrode pattern and the lower electrode pattern in the step (a); and (c) measuring an illuminance using the measured current, in which a voltage supplied to the lower electrode pattern is relatively higher than that of the transparent electrode pattern in the step (a).

Method of sensing illuminance using passive matrix organic light emitting diode display including illuminance sensor function and method of controlling the same

A PMOLED touch-sensing display panel using anodes as in-cell touch sensors is provided. The anodes and the cathodes are respectively and correspondingly configured into two or more electrically isolated areas of cathodes and anodes such that the heavy parasitic capacitance due to close proximity of the anode layer and the cathode layer is eliminated, hence providing a full dynamic range in sensing the changes in capacitance due to finger touches.
