Abstract: A data transfer controller for transferring display data to N individual (where N is an integer, N?2) display devices is disclosed. The data transfer controller includes a clock signal generating means, and a timing control means. The clock signal generating means generates clock signals. The timing control means adjusts the timing of the vertical synchronization signals included in the display data based on the clock signal for N individual display devices. The timing control means adjusts the timing of the vertical synchronization signals such that no vertical blanking period overlaps any other vertical blanking period, or adjusts the timing of the vertical synchronization signals such that no vertical display period overlaps a vertical display period of another display device among the display data transferred to each display device.

Abstract: There are disclosed methods for driving liquid crystal display apparatuses for certainly completing in a short time to performing a transition of liquid crystal molecules to a displayable alignment in liquid crystal display apparatuses such that an initial alignment of the liquid crystal molecules is different from the displayable alignment, typically an optically compensated bend mode liquid crystal display apparatus. A voltage is applied to a liquid crystal layer until display area in the liquid crystal layer is transformed to the displayable alignment. After the completion of the transition, a backlight is switched on to shift to a display-driving mode. In order to complete the transition in a short time, voltage pulse under the conditions (such as a frequency and a voltage value) determined in accordance with a temperature of a liquid crystal panel is applied to the liquid crystal layer.

Abstract: An image synthesis apparatus stores a synthesis order in which input images are to be synthesized with each other, and first and second synthesis numbers respectively designating how many of the input images are to be synthesized to generate first and second output images. The image synthesis apparatus synthesizes the plurality of input images with each other sequentially in accordance with the synthesis order, and stores a resultant synthesized image. When the stored synthesized image is the first output image, generated by synthesizing the first synthesis number of input images in accordance with the synthesis order, the first output image is output to an external destination. When the stored synthesized image is the second output image, generated by synthesizing the first output image with the remaining input images in the synthesis order, the stored second output image is output to the external destination.

Also, ingenuities are exercised on the period in which the potential difference is continuously applied between them and on the structure of picture elements.

Abstract: An image display device of this invention includes image memory (3) which is constructed of SRAM and which does not need any refreshing operation, image memory (3) being composed of MSB division memory (13) for storing MSB data of each pixel data item and lower-order bit division memory (14) for storing lower-order bit data other than the MSB data. In a normal mode MSB division memory (13) and lower-order bit division memory (14) are driven to cause the MSB data and the lower-order bit data to be read/written, whereas in an electric power saving mode only MSB division memory (13) is driven with lower-order bit division memory (14) remaining undriven to cause the MSB data to be read/written.

Abstract: An object of the present invention is, by eliminating a driver IC from the components of an liquid crystal display, to achieve a cost reduction, to eliminate a manufacturing step of mounting the driver IC onto an array substrate, and to reduce a thickness of the liquid crystal display. A driver circuit for an active matrix liquid crystal display comprises a resistive dividing type digital-to-analog converter circuit (DAC). An analog output voltage from the DAC is amplified by a signal amplifier element, and a liquid crystal element is driven by the amplified analog output voltage. The driver circuit is characterized in that a resistance element R is formed in an n+ layer of p-Si on an array substrate of the liquid crystal display, and a switching element Tr and a signal amplifier element are also formed on the array substrate.
