摘要

Method for displaying images on a large-screen organic light-emitting diode display, characterized in that use is made of an organic light-emitting diode (OLED) display (100) comprising an array of OLED display tiles (140) that are each formed of an array of smaller OLED display modules (130), each OLED display module (130) comprising a number of OLED pixels, wherein each OLED display module (130) includes an intelligent OLED module processing system (210), whereby, in order to display the images, data concerning the image to be displayed, provided by a general processing unit, in other words a system controller, are transmitted to tile processing systems (220) and from each tile processing system (220) towards the respective modules (130), characterized in that the OLEDs are driven by means of current sources, and in that in each OLED module processing system (210) the voltage across the current source (430) of the worst OLED (420) is compared to a pre-stored minimum threshold voltage value, and if said voltage is lower than the threshold voltage value, an adjustment of the power supply voltage is carried out.
