Abstract: A transmission method is provided for transmitting image data having pixels each comprising multiple sub-pixels provided for respective colors. The luminance of each sub-pixel provided for the corresponding color is represented by m-bit (m is an integer of 2 or more) luminance data R[m?1:0], G[m?1:0], and B[m?1:0]. Mapping is performed such that the bits provided for the same color at the same bit positions selected from the adjacent n (n represents an integer of 2 or more) pixels are sequentially arranged in the time direction so as to form a data unit. Data transmission is performed in units of data units (bit sets) thus mapped.

Abstract: A buffer circuit is driven with a low voltage and operates at a high speed has first and second comparators constituted by P channel and N channel MOS transistors provided between an input terminal and an output terminal of a buffer amplifier. A predetermined offset voltage is set for the comparing operation, and a switch circuit turns ON/OFF in response to an output signal from the first comparator and the output signal of the second comparator. A leading up of an output voltage from the buffer amplifier is accelerated by the current flowing from a power source line to the output terminal. The buffer circuit also includes an operation restricting circuit for restricting the comparing operation of the second comparator in a range of a dead band of the transistors.

Abstract: A source driver drives data lines of a liquid crystal panel in an inversion driving manner. The source driver includes multiple charge averaging switch groups in increments of pixel colors. Each charge averaging switch connects a pairing of the nearest two corresponding data lines assigned to the same color. These two paired data lines are driven with opposite polarities. In many cases, the nearest pixels assigned to the same color have the same gradation. Thus, by performing a charge averaging operation for each of the associated data lines that correspond to such pixels, such an arrangement provides a source driver having the advantage of low power consumption.

Abstract: A load is commonly driven by means of operational amplification means which buffers an input voltage and produces an output voltage; and by means of output acceleration means which outputs a large electric current greater than the electric current output from the operational amplification means when a voltage difference of a predetermined offset voltage or more exists between the input and output voltages. As a result, when a change has arisen in the input voltage, the electric current is supplied to the load primarily from the output acceleration circuit until the difference between the input and output voltages becomes the predetermined offset voltage or less. Subsequently, the electric current is caused to flow to the load from the operational amplification means until the input and output voltages become equal to each other.
