摘要： The liquid crystal display device includes a MLA operating circuit which reads from gradation data of [b2, b1, b0] stored in frame memories b2 in a period of the first frame, and b1 and b0 in periods T1 and T0 of the second frame to produce a column data signal 104 ([c2, c1, c0]), and a timing control circuit which controls a latch signal to column drivers so that the time ratio of the first frame to the second frame is 4:3 and the time ration of divided selection periods in the second frame is 2:1. With this, the number of change points of voltage level applicable in selection periods can be reduced whereby occurrence of a waveform distortion is minimized and a possibility of an uneven display in the liquid crystal display device is reduced.

摘要： the present invention provides a force transducer having high compression fracture strength and high detection sensitivity, thus satisfying both detection precision and reliability, and also a method of fabricating such a force transducer. The force transducer is so constructed that a compression force is transferred via a pressure transfer block to narrow strain gages, which protrude from the surface of a silicon substrate and provide a small pressure-bearing area. Therefore, large compression strains act on the strain gages and thus the detection sensitivity is increased. When the compression force exceeds a predetermined value, the pressure transfer block comes into contact with the surface of the silicon crystal, thus improving the fracture strength of the strain gages. These narrow, protruding strain gages can be fabricated easily by a single mesa etching process.
