Abstract
A clockless transmission system includes display controllerand display driver. Display controllerincludes data transmission circuitconfigured to output general data obtained by multiplexing a clock by coding serialized pixel data for each pixel data during a data communication interval and also to output a predetermined control signal during a blanking interval. Display driverincludes clock and data recovery circuitconfigured to output the pixel data from the general data transferred from the display controller and to increase a loop gain of a feedback loop in clock recovery such that the loop gain is larger than that when the general data is received, according to control data of the control signal, to recover and output a clock, and display driving circuitconfigured to output a signal for driving a display based on the pixel data and the recovered clock.
