Abstract: A cut-to-measure display device comprising a plurality of pixel groups (300) and a main controller. Each pixel group comprises one sub-controller (301) and a plurality of individually controllable pixels (305), out of which all are connected to the sub-controller of the pixel group and at least one is further connected (304) to a sub-controller of an adjacent pixel group. The main controller is connected to the sub-controllers and configured to selectively control the sub-controllers in order that the pixels display an image corresponding to predetermined image data. Cutting a display device with these features into an arbitrary geometric shape may disconnect some pixels from their respective sub-controllers. However, at least one pixel in each pixel group is connected to a further sub-controller which is operable to take the place of a sub-controller from which it has been cut off, so there is a low risk of completely disconnecting pixels.

The lighting system further comprising a spreading optical element arranged in front of the plurality of light emitting elements to shape the light emitted from the lighting elements, and a controller for varying a light emission angle range of light emitted from the spreading optical element by controlling each of the plurality of controllable light emitting elements. This allows the light emitted from the spreading optical element to be varied without varying any physical parts of the lighting system, because the controller now controls each of the light emitting elements, by e.g. dimming one or more of the light emitting elements or by switching one or more of the light emitting elements off.
