Abstract: Configurable large-area display system with a display (114) comprising a plurality of sub-displays that each contain an array of pixels (122), characterized in that it further comprises a central controller hardware and software block (110) containing software to control the display system (100) and to generate control data and video signals to be displayed on the display (114); a digitizer (112) that converts said control data and video signals to a digital signal compatible with the display (114); whereby the digitized control data and video signals are passed from one sub-display to the next, and whereby each sub-display is a control unit (116) capable of controlling the individual pixels (122) of said control unit (116) as a function of its position within the display (114) and of the received control data and video signals.

Abstract: A pixel module for use in a large-area display, in particular as part of a cluster (118) of a plurality of sequentially interconnected similar pixel modules (120) and driven by a central controller (116), comprising one or more pixel elements (122), characterized in that it further comprises a serial video data bus input (SERIAL IN) and one or more command input lines (CMD's In) electrically connected to inputs of a latch (210) having parallel inputs and outputs and which is clocked with a data clock input (DATA CLK); a current driver device for driving said one or more pixels (122) which is electrically connected to the outputs of latch (210) and to the data clock input (DATA CLK) and which includes a serial output port (SERIAL OUT) for transmitting the serial data to the next pixel module (120) in sequence; a first inverter (214), the output of which (DATA CLK “not”) can be used to drive the data clock input (DATA CLK) of the next pixel module (120) in sequence; a grayscale clock (GS CLK) input which is ele

Abstract: A display pixel module for use in a configurable large-screen display application, with an array of pixels (122) mounted at the front (200) of the module (120) and provided with input and output connectors (206-207), characterized in that at least some of the side walls (202) and of the upper and lower walls (203-204) are tapered inwardly, enclosing an angle (A) with the front (200) and in that it is provided with mounting means to fix the module on a mounting surface of a display.

Abstract: Method for controlling an organic light-emitting diode display, said display (400) comprising a plurality of organic light-emitting diodes (OLEDs) (212) having an anode and a cathode, said organic light emitting diodes (212) being arranged in a common anode configuration, whereby said diodes (212) co-operate with constant current sources (214) and are fed by means of a power supply, characterized in that a power supply compensation is applied, in which a voltage drop is measured across the current sources (214) and wherein the measured voltage drop is used as an indicator for the light output of the organic light emitting diodes (212) and wherein said power supply is adjusted in function of said measured voltage drop.

Abstract: The present invention provides arrangements for electroluminescent displays 10 comprising a packaged semiconductor light emitting element 12 that has a light emitting display side 16. A heat sink 22 is disposed in the region of a rear side of the light-emitting element 12 opposite to the display side. Electrical connections 28 from the light emitting element 12 pass through said heat sink 22. Drive circuitry 30 for the light emitting element 12 is connected thereto by the electrical connections 28 and spaced apart from the heat sink 22 in such a manner that at least one cooling channel 34 is defined between the heat sink 22 and the drive circuitry 30 for the passage in use of a cooling fluid.
