Signal transmission device and display using the same

Abstract:

A signal transmission device for transmitting touch data and a display device using the same are disclosed. The signal transmission device includes a plurality of integrated circuits driving touch sensors and outputting touch data obtained from the touch sensors, a controller controlling the integrated circuits and determining a touch input on the basis of the touch data received from the integrated circuits; and a plurality of lines connecting the controller and the integrated circuits in a multi-point manner. The controller and the integrated circuits communicate with each other in both directions via the lines. A data packet of differential signal transmitted between the controller and the integrated circuits includes a header interval, a register address interval, and a data interval allocated between a start dummy clock and an end dummy clock.
