Abstract:
A display unit comprising:a matrix display panel including display elements disposed at intersections of a group of row electrodes and a group of column electrodes;a memory in which display data is stored;a changing portion for generating an ON/OFF signal, wherein said ON/OFF signal is generated for lower order bits in each display data read from the memory with reference to a value of each of the lower order bits, and wherein said ON/OFF signal is generated for higher order bits by comparing a value indicated by the higher order bits with a predetermined value so as to output an ON signal when the value indicated by the bits is greater than the predetermined value;a column electrode control circuit for applying voltage to the group of column electrodes of the matrix display panel according to the ON/OFF signal from the changing portion; anda row electrode control circuit for applying row voltage to the group of row, electrodes of the matrix display panel.
