Title:
半導体装置
Document Type and Number:
Japanese Patent JP6961457
Kind Code:
B2
Abstract:
A method for transmitting image data to a display device at high speed is provided. Image data to be transmitted is input to a phase modulation portion, and is mixed with a high-frequency carrier wave. The carrier wave is modulated with a technique of phase-shift keying, and output to a transmission line determined in consideration of the transmission characteristics of the high-frequency wave. A phase regulating portion of the phase modulation portion has a function of adjusting the amount of change in phase with the use of an electric signal. A phase demodulation portion beyond the transmission line demodulates the modulated carrier wave and extracts the image data. The multi-bit image data can be transmitted by the technique of the phase-shift keying. The high-speed transmission enables serial conversion of the original image data and decreases the number of transmission lines.
