A method of producing a metal element of an electronic device on a substrate, including the steps of: forming a mixture of a material comprising metal atoms with a liquid, depositing the material from the liquid mixture onto a substrate, and then irradiating at least part of the deposited material with light to increase the electrical conductivity of the deposited material. A method of producing one or more elements of an electronic device, including the steps of: providing a substrate including one or more underlying elements of the electronic device and a thermally patternable layer overlying said one or more underlying elements; and using said one or more underlying elements to locally generate heat and thereby selectively induce a change in corresponding portions of said thermally patternable layer; and wherein either the change selectively induced in said corresponding portions directly results in the definition of one or more elements of the electronic device in a position determined by that of said one or more underlying elements, or alternatively including the additional step of using the change selectively induced in said one or more corresponding portions to facilitate the formation of one or more elements of the electronic device in a position determined by that of said one or more underlying elements. A method of producing an element of an electronic device, including the steps of: (a) providing a substrate; (b) depositing on said substrate a layer of a switchable material, which changes its physical or chemical properties upon irradiation with light or heating causing a change of its surface energy properties; (c) irradiatively inducing at selected regions of a layer of switchable material a change in physical or chemical properties that alters the surface energy of said selected regions and thereby forming a surface energy pattern on its surface; and (d) without removing said layer of switchable material in either irradiated selected regions or non-irradiated regions from the substrate depositing over the surface energy pattern produced in step (c) a material for forming an element of the electronic device such that the surface energy pattern controls the deposition of said material.

Production of electronic devices

A method of manufacturing a flexible display is provided, which includes depositing a first layer comprising a plurality of thin film transistors (TFTs) on a flexible substrate and depositing a second layer comprising a plurality of pixel electrodes above the first layer with each pixel electrode connected to a respective TFT via a respective via connector between the first and second layers. A display medium responsive to signals on the pixel electrode can be deposited on the second layer for displaying an image on the second layer. A third layer comprising color filters for filtering an image displayed on the display medium can be aligned to the second layer. The third layer can be deposited and aligned on the second layer such that each color filter is substantially aligned to a respective pixel electrode to compensate for distortions in the first layer caused by distortions in the flexible substrate.

Distortion tolerant pixel design

A semiconductor device architecture where the top pixel electrode is deposited in an off-set configuration, such as to overlap the COM electrode, and also the gate electrode of the neighboring device.

Off-set top pixel electrode configuration

A pixel architecture for compensating for distortions in a flexible substrate of a flexible display, including: a first layer including a thin film transistor (TFT) on a flexible substrate; a second layer disposed above said first layer including a pixel electrode coupled to said TFT for receiving a signal from said TFT; and a third layer including a color filter for filtering light displayed by said pixel, wherein said third layer is aligned to said second layer such that said color filter is substantially aligned to said pixel electrode, said alignment compensating for distortions in said first layer caused by distortions in said flexible substrate.

A rectifying diode comprising a semiconducting layer, a first electrode, and a second electrode, wherein the width of the region of closest contact between the two electrodes is on the order of the thickness of the semiconducting layer.
