Abstract: A control component for a current-driven optical media is provided. The control component includes thin film transistors (TFT) for driving pixels of an active matrix optoelectronic device. An additional electrode is provided in a separate conducting layer within the control component in order to add a separate capacitance (C2) that is coupled to the gate electrode of the control component to supplement the capacitance (C1) already coupled between the gate and source electrodes.

Abstract: A device comprising: a stack of layers supported on a support film and defining an array of pixel electrodes and electrical circuitry via which each pixel electrode is independently addressable via conductors outside of the array of pixel electrodes; and transmissive conductors supported on said support film at a first conductor level below said stack of layers in the regions of said pixel electrodes; wherein said conductors are light-transmissive and are connected within the first conductor level to a conductor outside the array of pixel electrodes; wherein said transmissive conductors exhibit a substantially higher transmittance for some wavelengths in the visible spectrum than for other wavelengths in the visible spectrum.

Abstract: The present invention relates to a control component for a current-driven optical media, for example a control component including thin film transistors (TFT) for driving pixels of an active matrix optoelectronic device. An additional electrode is provided in a separate conducting layer within the control component in order to add a separate capacitance (C2) that is coupled to the gate electrode of the control component to supplement the capacitance (C1) already coupled between the gate and source electrodes.

Abstract: A pixel driver circuit having only three conductive layers is described. The pixel driver circuit comprises a vertical driver transistor (26) spanning said three conductive layers, wherein a first of said conductive layers (22) on a first side of a middle conductive layer (32) provides a first source-drain connection (52) of said driver transistor, wherein a third of said conductive layers (34) on the opposite side of said middle conductive layer to said first conductive layer provides a gate connection (54) for said vertical driver transistor, and wherein said middle conductive layer provides a second source-drain connection (50) for said vertical driver transistor. The circuit also comprises a lateral switching transistor (30) with source-drain connections (44,46) in one of said three conductive layers.
