Abstract

A display module driving system wherein digital pixel data for an image to be displayed is provided to a plurality of column drivers on a row by row basis in serial format over a plurality of dedicated bus lines rather than a single parallel bus line. Digital pixel data for a complete image row is divided into segments, wherein the number of segments is each to the number of column drivers. Each segment is then serialized and transmitted to a corresponding column driver such that the digital pixel data for an entire row is transferred to each of the plurality of column drivers at the same time. The column drivers receive the segments and rearrange the data into parallel. The pixels are then transferred to a digital to analog converter, preferably two pixels at a time, where each pixel is converted into analog red, green and blue signals. An analog sample and hold module samples each analog signal for all of the pixels in a given row of the display and stores the signals in first capacitors of a plurality of sample and hold capacitor pairs. The sample and hold capacitor pairs allow analog signals to be sampled and held on a row by row basis such that when one capacitor in each pair stores one of the analog red, green and blue voltages for a subsequent row, the other capacitor transfers the analog voltage signal out for a current row to the column electrodes of the display.
