    摘要: A transistor having a channel width, W, and a channel length, L, defined by non-rectangular electrodes. The transistor is a thin film field effect transistor having an insulated gate electrode. One of a source and drain electrodes is connected to a display electrode and one is connected to a data line. The source and drain electrodes can be interdigitated to provide a desired W/L ratio. The gate is connected to a select line. An overlap region between a display electrode and a select line for another pixel defines a capacitor. The transistor is fabricated to be situated behind the display electrode so as to maximize an aperture ratio. The design enables the use of conventional printing methods, such as screen printing, ink jet printing, printing through a stencil, flexo-gravure printing and offset printing.

    摘要: In accordance with the invention, an optical fiber grating device is made by providing a fiber with an electrically actuable component optically responsive to voltage or current and a plurality of conductive elements to locally activate the component and thereby to produce local optical perturbations in the fiber. In a preferred embodiment, a fiber is provided with a core of liquid crystal material and a plurality of periodically spaced microelectrode pairs. Application of a voltage to the microelectrodes results in a periodic sequence of perturbations in the core index which produces a grating. When the voltage is switched off, the grating switches off. Other embodiments utilize helical conductive elements.
