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.

摘要： A method and system for displaying an image on a liquid crystal display (LCD) that may reduce power consumption. The method and system can include calculating a luminance for pixels in an image in a LCD based upon a light spread function and brightness values of light emitting diodes (LEDs). The method and system can also include changing a brightness of an LED based upon a consideration of the gray value of the pixels and the distance of the pixels from a dominant LED. The method and system can further set the brightness of the LED units to a brightness substantially greater than or equal to a gray value of each pixel of the image.

摘要： A method is described for driving matrix displays which are made up of a plurality of lines with individual pixels, which lines are configured as rows and columns, wherein individual lines are driven selectively by rows being activated for a defined row addressing time and an operating current or a corresponding voltage being applied to the columns in correlation with the activated row corresponding to the desired brightness in the pixels. In order to improve the performance of the display, the row addressing time for each row is determined as a function of the maximum brightness of all the columns of the row.
