摘要
A method and unit for controlling a passive matrix-OLED-display with OLEDs assembled in matrix form, wherein columns for controlling an OLED are connected with a current source, and rows are connected consecutively during row addressing time. The lightness of a pixel located on the intersection point of a column with an addressed row is influenced by the turn-on time being within the row addressing time and by the amplitude of the column current. To reach an energy-efficient control it is proposed to control the lightness of the pixel subject to the charge quantity converted into light and subject to a charge quantity during a post luminescence time and converted into light by switching the column potential-free during post luminescence time and considering the charge quantity stored in the capacity of OLEDs before the addressing at determination of the charge quantity converted at the OLED.
