摘要： The object of the invention is to provide a drive method suitable for driving a fast-responding STN liquid crystal display device which ensures a minimized cross talk and improved contrast in display. The drive method comprises a memory means for storing display data corresponding to a plurality of lines, a function generating means for generating a drive function for the row electrodes, an arithmetic means for computing the outputs from the foregoing means, a column electrode drive means for driving the column electrodes in dependency on the output from the arithmetic means, and a row electrode drive means for driving the row electrodes in accordance with respective row electrode drive functions. As a voltage function to be applied to each row during drive operation, a sum of a plurality of orthogonal functions is utilized. Thereby, degradation in contrast due to display patterns as well as the cross talk can be minimized. Further, arithmetic operation can be simplified in gradation display since application of a compensating voltage waveform is no more required.

摘要： A reflective-type display device having a light modulating layer, including a host dispersed with light scatterers, which is held between two transparent electrodes; and a light absorbing layer disposed in back of the light modulating layer. The size of each light scatterer or the nearest distance between the adjacent light scatterers is nearly equivalent to the wavelength of incident light at least in two-dimensional directions. The refractive index ratio relative to incident light between the light scatterers and host is changed from 1 to 1.5 or more depending on the magnitude of a voltage applied across the electrodes.

摘要： On a liquid crystal panel, plural areas whose number is larger than that of temperature sensors are defined. In a memory, temperature relation information representing a relation between an output value of a temperature sensor and a temperature of each of the plural areas is stored. A controller acquires the output value of the temperature sensor and estimates, based on the temperature relation information and the acquired output value, the temperature of each of the plural areas. According to this configuration, the temperature of each of the plural areas defined on the liquid crystal panel can be obtained with a small number of temperature sensors.
