摘要： A driving device for a display apparatus having excellent contrast and a high display quality without crosstalk and display irregularities, and a driving method for the same are provided. In the driving device, scanning signals and data signals having a plurality of periodical inactive portions in one frame are applied to respective display dots. In the inactive term, a fixed voltage is applied to each of the display dots. The signal applied to the display dot is divided into small terms by the inactive portions, resulting in more high frequency components in a voltage signal applied to the display dot. As a result, the frequency components of a driving signal applied to the display dot are averaged. Further, a complete orthogonal function having 2.sup.r base function series is used, and a desired display data is completely reproduced on the display apparatus by an arithmetic process assuming auxiliary data in accordance with the number of the scanning electrodes.

摘要： In a liquid crystal display device having a simple matrix liquid crystal display panel including a plurality of scanning electrodes disposed in parallel with each other and a plurality of data electrodes disposed in parallel with each other so as to cross the scanning electrodes, the scanning electrodes are divided into a predetermined number of sub-groups, and each sub-group is successively driven by utilizing an orthogonal function. For a selection, a signal having an electric potential of .+-.Vr, which is a selection pulse string according to the orthogonal function, is applied to the respective scanning electrodes as a scanning electrode driving signal. For a non-selection, a signal having an electric potential of 0 is applied to the respective scanning electrodes as the scanning electrode driving signal. On the other hand, a data electrode driving signal having an electric potential proportional to a sum of products of a display pattern and the scanning electrode driving signal is applied to the respective data electrodes. A bias value "A", which is a proportional constant therefor, is set in a predetermined range. Thus, a uniform display with a high contrast enabling a fast response can be realized while suppressing a frame response phenomenon and display inconsistencies.

摘要： A multiplex-driven liquid crystal X-Y matrix display in which the electrodes are divided into several blocks and a driving voltage is independently applied to each of the blocks. Each driving voltage has a magnitude that is different from the remaining drive voltages. The display panel is free from nonuniform or deteriorated contrast even if it has a large number of scanning electrodes. Besides, for a color display, the color balance is favorably adjusted, realizing a high quality picture image.

摘要： The memory interface circuit converts an input data signal into multi-scan data signals used for a multi-scan type liquid crystal display. The memory interface circuit includes: a memory for storing one frame of the input data signal corresponding to the display panel, and a control circuit for controlling write/read operations for the memory so that the input data signal is sequentially written in the memory in a single-scan manner, and that data stored in the memory is read out as first and second multi-scan signals in a multi-scan manner. The control circuit controls timing of read operations so that a read operation for the second multi-scan signal is started a predetermined time after that for the first multi-scan signal is started, the predetermined time being equal to a delay time of a write operation of the input data corresponding to the second portion with respect to that corresponding to the first portion.

摘要： A liquid crystal display cell using cell substrates of a flexible organic polymer film and containing liquid crystals injected in a space between the cell substrates. Spacers are dispersed between the cell substrates and immobilized by an orienting layer for orienting liquid crystal molecules. A thin glass substrate can be substituted for the flexible organic polymer film. The liquid crystal display cell is produced by a method including the steps of creating a liquid crystal molecule orienting solution having spacers dispersed therein, applying the orienting film solution containing the spacers to the cell substrates, subjecting the applied solution to a curing treatment, sealing liquid crystals in a space formed between the cell substrates in which the interior thickness corresponds to the diameter of the spacers. The spacers are immobilized by the orienting film during the curing step. The spacers, rather than being mixed in the orienting solution before it is applied, can be scattered on the substrate before the solution is applied or scattered on the solution after it is applied to the substrate.

摘要： A driving voltage generating circuit of a matrix-type display device includes a voltage dividing resistor group composed of a plurality of voltage dividing resistors connected in series, for dividing a potential a difference of a reference voltage. It also includes operational amplifiers for generating and outputting row voltages (a selective voltage and a non-selective voltage) to be applied to row electrodes, by subjecting each voltage obtained by voltage division to impedance conversion. A p-channel MOSFET and an n-channel MOSFET as analog switches for altering a level of each voltage thus generated are provided in parallel with voltage dividing resistors at ends of the voltage dividing resistor group. With this arrangement, the number of elements necessary for the circuit, for example, MOSFETS and level shifters for controlling the MOSFETS, can be decreased. Therefore, the size of the driving voltage generating circuit can be reduced. As such, price lowering and reduction of power consumption can be achieved.
