    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 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 for driving an active matrix organic light-emitting diode (AMOLED) display. The method may be used to digitally drive the AMOLED display in a way that limits the susceptibility of the AMOLED display to certain problems arising out of digital driving techniques, such as image sticking or low display lifetimes. The method involves generating compensation factors corresponding to each pixel of the display and using those compensation factors to control the illumination of the display. The aspects of the method that incorporate the operation point for generating a compensation factor may also be applied to analog driving of AMOLED displays.
