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.
