Bus interface technology

Abstract

The invention, in part, provides a method of (and corresponding apparatus for) receiving (and similarly transmitting) data signals over data lines. Such a method of receiving comprises: organizing said data lines into groups, each group having N input data signals and M reference signals, wherein N is a non-zero, positive integer; associating M reference signals on M reference lines with each group of N input data lines, wherein M is a non-zero, positive integer and N>M; and receiving data on said data lines and reference signals on said reference lines; and determining, for each group, data values on said data lines according to differences between signal parameters on said N data lines and signal parameters on said M reference lines, respectively.

Description

technical field [0001] The invention relates to a bus interface technology in a flat panel display system. Background technique [0002] A pixel on a flat panel display generally corresponds to the intersection of source lines (typically corresponding to the columns of the matrix) and gate lines (typically corresponding to the rows of the matrix). As display formats tend to increase in size, the rate at which data must be transferred to the display must then increase. For example, with the same clock frequency, Ultra Extended Graphics Array (UXGA) (with 1600 columns x 1200 rows, or 1600 x 1200) requires four times the data transfer rate as Super Video Graphics Array (SVGA) format (800 x 600 ). In practice, this may mean that UXGA may require 4 times as many data lines in the interface bus as SVGA. But if the number of data lines per interface bus is kept the same, the UXGA interface bus must operate at a frequency four times greater than that of the SVGA interface bus. ...
