Circuit for data synchronization of I2C time controller in display device and method thereof

摘要

A method of controlling an interface between an I2C master in a time controller for a liquid crystal display and an external memory may include causing a pre-scaler to determine whether or not a first clock signal from the I2C master to the external memory is synchronized with a second clock signal from the external memory to the I2C master. If the first clock signal is not synchronized with the second clock signal, the pre-scaler stops transmission of a third clock signal for an I2C interface with the external memory to the I2C master.
