Abstract
A data transmitting device and a flat plate display using the same are disclosed. The data transmitting device includes a current generator comprising a plurality of constant current sources connected in parallel and a plurality of switches connected to output terminals of the constant current sources, respectively, the current generator configured to switch the switches independently according to a preset digital current control signal and adding up the currents supplied from the constant current sources via the tuned-on switches to output; a current amplifier configured to amplify and output the output current of the current generator; and a line driver configured to generate and output a low voltage differential signal according to input data by using a constant current such as the amplified current of the current amplifier.
