Method of driving a liquid crystal display device and a driving circuit for the liquid crystal display device |
摘要 |
A method of driving a liquid crystal display device by selecting simultaneously a plurality of lines in a liquid crystal display element characterized in that display data are temporality stored in memories; the data are read out plural times from the memories, and arithmetic operation are performed to the read-out data to produce signals to be applied to data electrodes, wherein the picture area is divided into a plurality of picture area blocks each including scanning lines the number of which are a multiple of a natural number of simultaneously selected scanning lines; the memories are divided into a plurality of memory blocks each having capacity capable of reading and writing data displayed on the picture area blocks; fames for writing are made in synchronism with frames for reading the data, and a memory block undergoes a predetermined number of times of reading, and then new display data are written into said memory block.
