Abstract
A data transmission method and apparatus that is adaptive for minimizing the power consumption and the electromagnetic interference. A bit data to be transmitted is delayed during at least one bit interval. The bit data to be transmitted is substituted by an identity to the delayed bit data. The identity is transmitted to a transmission line.

A driver for a display, comprising:
- a controller supplying pixel data comprising a plurality of bits;
- a data substitution unit receiving the pixel data and transmitting pixel representation data having a frequency of bit transitions which is less than a frequency of bit transitions of said pixel data;
- and
- an integrated circuit connected to said data substitution unit and receiving the pixel representation data via a data bus, reconstructing the pixel data, converting the pixel data to analog pixel data, and supplying the analog pixel data to the display.
