摘要： 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.

摘要： 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 sift 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.

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.

摘要： A display device includes a display that includes display elements arranged in lines of a matrix. Each display element is configured to emit light based on a video signal that is received by the display. A proportion determiner is configured to determine, for each line, a proportion of a single frame period during which each display element of a corresponding line is not to emit the light. A signal converter is configured to convert an amplitude of the video signal for each line according to the proportion determined for each line. A signal output is configured to output the video signal converted by the signal converter to the display as a converted video signal. A scanner is configured to output a scanning signal to the display for each line for inputting the converted video signal to the display elements of each line based on the proportion determined for each line.

摘要： When composite image data including parts that were respectively in different data formats before combining, is conventionally edited, the whole composite image data is edited by using a same algorithm. The algorithm may not be an optimum algorithm for a certain part of the composite image data. In an improved structure, the format conversion unit 142 converts the format of the combining target image data, attaches, to each piece of pixel data, a flag indicating the data format before the conversion, and outputs the pixel data with the flag. The combining engine 143 combines together the image data output from the format conversion unit 142.
