FIELD: electricity.
SUBSTANCE: invention is referred to devices based on organic LEDs and touch sensors for obtaining of near-field image. The device contains cathode, anode and active unit where anode is divided into a number of anode segments and each segment is defined by OLEDs (organic LEDs); capacity measurement unit made to measure current value of capacitance for each anode segment in regard to reference point and to detect changes in current values of capacitance for a number of anode segments depending on relative position of the dielectric object, which is drawn near device based on OLEDs.
EFFECT: increasing reliability of near-field imaging.
