Abstract: A pixel structure is provided comprising a plurality of sub-pixels, each sub-pixel comprising at least two sub-sub-pixels, each sub-sub-pixel being for the emission of light of one of at least two colors, the sub-sub-pixels being uniformly arranged within the sub-pixel, each sub-pixel of one pixel comprising the same arrangement of sub-sub-pixels. Furthermore, a reflective display comprising pixels with the pixel structure of the invention is provided, having an high image quality.

Abstract: The present invention relates to a method of controlling a modular, tiled, large-screen emissive display application, e.g. an OLED display application. The method of controlling e.g. includes a first control level (214) for controlling the emissive devices, a second control level (212) for controlling the emissive display modules and a third control level for controlling the emissive display tiles (210). The number of control levels can be larger or it can be restricted to two levels. The method of controlling according to the present invention allows for similar control and calibration algorithms to be run at all levels, and allows for distributed processing in order to reduce bandwidth requirements and processing complexity. Furthermore, the control method of the present invention includes a method of operating and a method of monitoring a modular, tiled, large-screen emissive display.

Abstract: The present invention relates to a configurable emissive display tile, e.g. an organic light-emitting diode (OLED) display tile and associated methods for use in a tiled large-screen display application. The OLED tile assembly of the present invention is capable of operating either as an autonomous display or, alternatively, may operate within a set of OLED display tiles forming a larger tiled display. An embodiment of an OLED tile assembly (100) according to an embodiment of the present invention is shown in FIG. 1C, including a power supply (158), a cooling system with cooling fans (160) and cooling blocks (146) and a control system, comprising a control board (154) with processor, an OLED board (142) and a substrate (140).

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 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.
