    摘要: A system is disclosed for driving a segmented type liquid crystal display comprising a thin film transistor (TFT) array including a plurality of TFTs each having a gate line, a source line, and a drain line, a pair of substrates with one carrying the thin film transistor array coupled to a plurality of segmented display electrodes and the other carrying a common electrode opposite to the segmented display electrodes, a liquid crystal material interposed between the pair of substrates. The system is characterized by a source line and drain line driving circuit for driving the source line and the drain line with a first voltage waveform and a second voltage waveform in such a manner that the ratio of the first voltage amplitude to the second voltage is so selected that both charging and discharging voltages in the forward and backward directions are zero when the TFTs are off.In another aspect of the segmented type display of the present invention, there is additionally provided a separating element for separating the thin film transistor array from the liquid crystal material. In a further aspect, the plurality of pairs of the segmented display electrodes and the common electrodes are allotted equally to each of the pair of substrates.

    摘要: A liquid crystal display device comprises a sandwich structure of support plates with a layer of liquid crystal filled therebetween. One support plate has an array of thin film transistors and thin film capacitors both formed thereon, while the other support plate has a counter electrode formed thereon. One of a pair of electrodes of each thin film capacitor on the one support plate is offset from the counter electrode at any area other than area where they form an effective capacitance element, the other the area where they form an effective capacitance element, the other capacitor electrodes serving as display electrodes.

    摘要: A method of forming a thin-film pattern such as a thin-film circuit component comprises successive formation of a first metal layer and then a photo resist layer on a substrate by the utilization of a photoetching technique. The substrate having the first metal layer and the photo resist layer on the top of the first metal layer is deposited with second metal layers which are discontinued from each other, one of the second metal layers being deposited on the top of the photo resist layer while the other of the second metal layers is deposited directly on the substrate around the first metal layer. The substrate assembly is then immersed into a solvent bath to remove the photo resist layer together with the second metal layer resting thereon and is thereafter immersed into an etchant bath to remove the first metal layer, leaving the second metal layer on the substrate.
