摘要： A liquid crystal display comprises (a) a first transparent base; (b) a plurality of first picture electrodes on the first transparent base; (c) a plurality of data lines for supplying electrical signals to the first picture electrodes; (d) a second transparent base, parallel to and spaced apart from the first transparent base; (e) a plurality of second picture electrodes on the second transparent base; (f) a plurality of varistor elements made of a varistor material comprising zinc oxide as a primary metal oxide and cobalt and praseodymium oxides as additive metal oxides, in amounts of between 0.1 and 8.0 atom % cobalt and between 0.08 and 8.0 atom % praseodymium, one varistor element being associated with and in electrical contact each second picture electrode; (g) a plurality of scan lines for supplying electrical signals to the second picture electrodes via the respective associated varistor elements; and (h) electrooptically active liquid crystal material between the first and second picture electrodes. In a preferred embodiment, the plurality of varistor elements is in the form of a varistor array comprising an integral body of varistor material having two major opposing faces, one of the opposing faces having an array of indentations thereon, each indentation defining a varistor element.

摘要： A laminar sensor (1) for detecting changes on a laminar substrate (35). The sensor includes a laminar sheet (3) which has a first surface (5) and a second opposite surface (7), and is made from a conductive polymer composition which exhibits temperature dependent resistance behavior, preferably PTC behavior. A plurality of sensing elements (12) are electrically connected, preferably in series, on the sensor. Each sensing element is formed as an electrode pair containing a first electrode and a second electrode. The first and second electrodes (9, 11) may be on the same surface of the laminar sheet or on opposite surfaces of the sheet. Two electrical leads (17, 19) are present for connecting the sensing elements into a circuit, which may be used to detect changes in resistance which occur when a sensing element is exposed to an elevated temperature, a change in pressure, or a solvent.
