Abstract: An intelligent lighting module for use in a lighting or display module system which is composed of an array of lighting modules, each of the lighting modules being provided with a display board with an array of individual pixel lighting elements and with a control board capable of controlling serial input data from a video source for displaying video as well as of controlling digital communication input data from a lighting console for creating digital lighting effects, wherein the display board includes a drive buffer and an array of pulse-width modulation (PWM) drivers which are connected to the lighting elements.

Abstract: A method of optimizing lifetime of an OLED display element and an OLED display element with optimized lifetime for possible use in a tiled display, while maintaining light output are described. It compensates an OLED operating parameter such as supply voltage and/or on-time of the operating current based on at least one environmental factor which affects aging and on at least one operating factor which is indicative of aging, e.g. by determining the brightness of an OLED display element. To optimize the light output, pre-charge of the aged OLED display elements can be optimized. The knowledge of the working temperature of OLED tiles may be used to regulate the cooling and thus the working temperature, thus improving the lifetime of the display. Furthermore the intensity and contrast of the display illumination may be set within predefined limits to reduce the aging.

Abstract: The present invention is a pre-charge circuit integrated within the drive circuitry of a common anode, passive matrix, large-screen organic light-emitting diode (OLED) display device for overcoming the inherent capacitance characteristics COLED of the OLED devices therein. More specifically, a first pre-charge circuit of the present invention includes a MOSFET device integrated within the normal drive circuitry for applying a pre-charge voltage to the cathode of a given OLED device just prior to the desired “on” time, thereby overcoming COLED rapidly. A second pre-charge circuit of the present invention integrates within the normal drive circuitry a method of connecting the anode of a given OLED device to a positive voltage while concurrently connecting the cathode to ground just prior to the desired on time, thereby overcoming COLED rapidly.

Abstract: An organic light-emitting diode drive circuit for a display application includes a plurality of organic light-emitting diodes (OLEDs) having an anode and a cathode, the organic light-emitting diodes being connected to anode lines and cathode lines, and at least one drive circuit. The organic light-emitting diodes are arranged in a common anode configuration, whereas the drive circuit is configured as a common anode drive device, so that each concerned cathode line can be connected by a respective first switch to a current source and so that each concerned anode line can be connected by a respective second switch to a positive power supply. The respective first switches are configured such that, when a cathode line is in use, a connection is made between the cathode line in use and the respective current source and, when the cathode line is unused, the cathode line is connected to a positive power supply.

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.
