DISPLAY DEVICE Television receiver has a liquid crystal display formed of a lattice of display elements made from liquid crystal material, each element being individually actuable, the lattice of elements being backlit by fluorescent tubes whose light intensity and duration of operation can be controlled. The video signal has a 70Hz scan rate and a scan period of 14mS, each picture of display information having an 8-bit word for each display element, a word beginning with the most-significant-bit and ending with the least-significant-bit. In the processing for the display of the most-significant-bits of the words, the frame store outputs the first bit of each word and sends the bits to a control unit for an array of drivers, one being assigned to each row and column of the lattice for setting of each element to its appropriate condition. Once all the elements are set, the driver control unit activates the tubes 4 for a time duration and intensity appropriate to the significance of the bit. |
