Abstract: An image display device and method are described for displaying an image distributed over plural display tiles. The image display device has a plurality of backlight light sources for illuminating plural display tiles. Contiguous zones of at least one image pixel are defined in each display tile such that each zone has at least one associated backlight light source. In particular for each edge zone of each display tile a backlight brightness driving level is determined based on brightness level target values of pixels of the edge zone and based on brightness level target values of pixels of at least one other zone of another display tile adjacent to the edge zone.

Abstract: The present invention relates to image projection and provides a method and system for performing color calibration of light sources and correction towards a color target, for example a whitepoint target.

Abstract: A projector system includes a monitor that measures irradiance of projected light. The monitor direct light from a light source that is sampled in an optical path of the projector onto a sensor. The detector also receives light from a calibration light source. A processor is configured to process an output signal of the sensor to determine irradiance of the projected light. The processing may comprise applying a colour transform and lumped coefficients. The projector system may be configured to take corrective action if the monitored irradiance exceeds a threshold. One application of the disclosed apparatus and methods is improving safety.

Abstract: A system for distributing digital cinema content (DCC) to cinemas integrates with content creators, distributors and cinemas.

Abstract: Example embodiments provide systems and methods for correcting non-uniformities of a light beam generated by a multi-emitter light source. In some embodiments a phase modulator displays patch lenses to correct for the non-uniformities. In some embodiments each region of the phase modulator is illuminated by a beam generated by one emitter of the multi-emitter light source. Such region of the phase modulator may display a patch lens for correcting non-uniformities in the corresponding beam which illuminates the region.

Abstract: A method for transferring data between a server (2) and an equipment (1) which cannot establish a direct wireless communication with the server. The method comprises each of at least two user devices (3, 4, 5, 7) establishing a first wireless communication channel with the equipment and establishing a second communication channel for connecting to the server; establishing an indirect wireless communication between the equipment and the server via the at least two user devices; transferring data between the equipment and the server through the established indirect wireless communication. A first and a second part of the data is transferred via a first and a second user device of the at least two user devices, respectively. The first and second part of the data are a same part or different part of the data. The first wireless communication channel is established only when the user devices are within a predetermined distance from the equipment.

Abstract: A solid state die such as an LED (or OLED) die that is fitted in a hole such as a through hole in a carrier substrate such as a PCB. The die is to be connected to the PCB e.g. to tracks on the PCB. The electrical contacts on the die are arranged to be (e.g. substantially) in the same plane as the contacts on the carrier substrate such as the PCB. This is achieved by the holes in the substrate such as the PCB being adapted so that the dies fit into the holes or openings, i.e. are each taken up into an opening before electrical contacts are made.
