    摘要： 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.

    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.

    摘要： 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.

    摘要： A display device includes luminescence pixels that each include a driving transistor, a luminescence element, and a switching transistor that switches between conduction and non-conduction between a data line and an anode or a cathode of the luminescence element. A data driving circuit supplies a signal voltage to the data line, and a bias supplying circuit supplies a predetermined bias voltage to the data line. A controller applies the predetermined bias voltage to the anode or the cathode of the luminescence element by causing a non-conduction state between the data line and the data driving circuit, causing a conduction state between the data line and the bias supplying circuit, and switching the switching transistor ON within a period in which a signal current does not flow to the luminescence element.

    摘要： Display devices and methods capable of reversing brightness deterioration in electroluminescence elements while maintaining display quality, with simple pixel circuits and no manufacturing yield reduction, are provided. A display device includes luminescence pixels that each include a driving transistor, a luminescence element, and a switching transistor which switches between conduction and non-conduction states between a data line and the luminescence element. A data driving circuit supplies a signal voltage to the data line and a bias supplying circuit supplies a specified bias voltage to the data line. A control unit applies the specified bias voltage to an anode or cathode of the luminescence element by causing conduction between the data line and the data driving circuit, causing non-conduction between the data line and the bias supplying circuit, and turning the switching transistor ON, all within a period in which a signal current does not flow to the luminescence element.
