Abstract: A device including a stack of layers defining a first conductor pattern at a first level of the stack and one or more semiconductor channels in respective regions, connecting a pair of parts of the first conductor pattern, and capacitively coupled via a dielectric to a coupling conductor of a second conductor pattern at a second level of the stack. The stack includes at least two insulator patterns over which the first level or second level conductor patterns is formed. A first insulator pattern occupies one or more semiconductor channel regions to provide the dielectric. The second insulator pattern defines one or more windows in the one or more semiconductor channel regions through which the second conductor pattern contacts the first insulator pattern other than via the second insulator pattern. The second insulator pattern overlaps the first insulator pattern outside the one or more semiconductor channel regions.

Abstract: A manufacturing process for forming a flexible assembly suitable for a curved sensor or display including a stack of layers defining electrical control circuitry is presented. The flexible assembly has a curved configuration and comprises at least first and second components (4, 8) laminated together in a stressed configuration due to their curvature. While the assembly is in said curved configuration at least the first and second components (4, 8) are cut to obtain one or more edges which are aligned to each other.

Abstract: A device having a stack of layers defining source and pixel conductors at a first level, gate and common conductors at a second level, semiconductor channels between the source and pixel conductors and gate dielectric capacitively coupling the semiconductor channels to the gate conductors. The pixel and common conductors are configured such that, in use, a change in potential difference between the pixel and common conductors in a pixel region induces a change in one or more optical properties of a liquid crystal material in the pixel region.
