DRIVING APPARATUS WITH 1:2 MUX FOR 2-COLUMN INVERSION SCHEME

摘要

A driving apparatus comprises a plurality of pixels provided in an array employing the 2-column inversion scheme, a 1:2 multiplexer and a data driving unit. Each pixel comprises a plurality of sub-pixels corresponding to different colors respectively. The 1:2 multiplexer coupled to the two pixels multiplexes a data source over one of the sub-pixels in the m column and the other of the sub-pixels in the m+1 column of the same row corresponding to the same color and the same polarity, wherein m is positive integers. The data driving unit is coupled to the 1:2 multiplexer through a plurality of data lines and provides the data source to the 1:2 multiplexer. The data lines do not have to switch between sub-pixels, nor polarity, which is beneficial for power consumption, and for front-of screen performance, which may be influenced by artefacts caused by the switching of the multiplexer.
