A liquid crystal display comprises an array of pixels having associated logic integrated into a semiconductor back plane. The logic includes a plurality of first latch means (12,14), each having an output which is input to a multiplex latch means (19), the output of the multiplex latch means being displayed. One of the first latch means is selected to provide data to be loaded into the multiplex latch means, thereby enabling the first latch means to be updated with new data whilst other data is being displayed. In use, data bits having a first significance are viewed for a time which is longer than that for data bits having a lesser significance. The viewing time for the data bits having said first significance is divided into a plurality of shorter intervals, the other data bits being displayed in time slots interposed between successive intervals. Data having said first significance is stored in one of the first latch means, so that this data does not have to be reloaded for each interval. |
