Abstract: A data transmission device which improves data transmission efficiency is disclosed. A data transmission device includes a decoder converting a first binary data to a ternary data, a ternary data generator coupled to the decoder and generating three logic levels corresponding to a power source voltage, an intermediate voltage, and a ground voltage, the intermediate voltage having a voltage level between the power source voltage and the ground voltage, a ternary data detector coupled to the ternary data generator and converting the three logic levels from the ternary data generator to pairs of second binary data, and an encoder coupled to the data detector and restoring the pairs of second binary data to the first binary data.

Abstract: A system for displaying an image converts an input pixel data for output onto a display device of a different resolution. An apparatus outputs a plurality of first pixel data of the input resolution. A converting apparatus assigns at least one of a plurality of weighted values and partially amplifies the plurality of first pixel data to output a plurality of second pixel data. The display device is coupled to the converting apparatus to receive the plurality of second pixel data, and the display device displays the image of a second prescribed resolution based on the plurality of second pixel data.
