摘要： In a low power consumption data transmission circuit and method, and a liquid crystal display apparatus using the same, 24-bit display data is transmitted from a transceiver circuit to a receiver circuit through a transmission line so that the display data is displayed on a liquid crystal panel. The transceiver circuit has a holding circuit including an 8-stage shift register. The transceiver circuit outputs 24-bit data to the transmission line by use of first and second output circuits when data different from data held in the holding circuit is to be transmitted from the transmission line and outputs data indicative of a hold position in the holding circuit from the second output circuit when the same data as that held in the holding circuit is to be transmitted from the transmission line. When the data indicative of a hold position is transmitted and received, the receiver circuit decodes or restores the received hold position indicating data into 24-bit display data by use of data held in a holding circuit provided in the receiver circuit.
