Abstract: An apparatus and a method for data signal scattering conversion. The apparatus includes a scattering multiplexer, a digital-to-analog converter, and a scattering demultiplexer. The scattering multiplexer is for receiving p digital data signals and outputting the q-th digital data signal of the p digital data signals. The digital-to-analog converter is to perform digital-to-analog conversion of the q-th digital data signal and output an analog data signal. The scattering demultiplexer has p output terminals, and is used for outputting the analog data signal through the q-th output terminal. Offset voltages output from the digital-to-analog converter are scattered over a number of data lines so that undesired points with abnormally deep or light colors due to the output offset voltages, are difficult to perceive.
