Abstract:
A data transmission apparatus for a display, comprising:a controller supplying pixel data comprising a plurality of bits; a data substitution unit receiving the pixel data, generating pixel representation data from the pixel data, and transmitting the generated pixel representation data over a data bus, wherein each bit of the pixel representation data has a first logical value if a bit of a currently supplied pixel data and a bit of a previously supplied pixel data are the same, and wherein each bit of the pixel representation data has a second logical value if the bit of the currently supplied pixel data and the bit of the previously supplied pixel data are different; and an integrated circuit connected to said data bus receiving the transmitted pixel representation data, reconstructing the pixel data from said received pixel representation data, converting the pixel data to analog pixel data, and supplying the analog pixel data to the display.
