Abstract: Method for manufacturing an organic light emitting device or a blank for forming therefrom an organic light emitting device as well as such a OLED or blank, the organic light emitting device having a light emitting area with two opposite first sides and two opposite second sides, the method comprising at least the following steps: providing a substrate; depositing and partly removing a layer of transparent conductive material on the substrate for forming parallel anode lines which extend between the first sides; depositing and partly removing at least one conductive layer for forming contacts which are connected anode lines; wherein a photoresist layer is deposited so that it fully extends over contacts adjacent the at least one second side except for at least one contact position per cathode line, via which an electric contact between a respective cathode line to be formed and a respective contact is established.

Abstract: A display device comprises a plurality of electroluminescent display pixels and a plurality of semiconductor elements (“chiplets”), each pixel being electrically connected to the output of one or more of said semiconductor elements through a via hole in an electrically insulating layer for addressing the plurality of display pixels, and a plurality of colour filters and/or downconverters. The colour filters and/or downconverters and the semiconductor elements are provided on the same surface of the device.

Abstract: An active matrix display comprises a display area of the matrix comprising drive circuitry including a control circuit comprising chiplets outside the display area. The output of the control circuit is distributed among the plurality of chiplets. This arrangement is advantageous in that the chiplets allow for a much smaller fan-in and fan-out structure, thus allowing a much larger percentage of the substrate to be devoted to display area.

Abstract: An optical sensor array comprises a photo-sensitive area formed by an array of chiplets having individual light-sensitive elements, each element configured to produce a signal or signals in response to incident light. The displacement of a chiplet from a predetermined position is derivable from the output signal or signals of the element or elements associated with the chiplet. The arrangement provides a method of measuring the displacement of at least one chiplet in an active display.
