    摘要: A multi-channel display driver circuit incorporating modified D/A converters has a plurality of digital comparators connected to a number generator. Each digital comparator has an output, a digital data input and a reference input. The reference inputs of all digital comparators are connected to the number generator and the outputs are respectively connected to corresponding data channels of a display. By the proposed technique, each digital comparator obtains a unique non-sequence reference signal, and then compares it with the input digital data signal. Since the non-sequential signals are input to the reference input of the digital comparator, the overshoot distortion, the harmonic distortion and the electromagnetic interference problems are prevented. Therefore, the precise imaging can be obtained with this signal modulation technique in small circuit size.
