Abstract
A large number of display elements having a function to change a display state of a pixel by supplying electric power are arranged in a matrix form to constitute a two-dimensional pixel arrangement, and a controller for changing display states of these plural display elements is prepared. Several divisional modes indicated by divisional levels n are defined and the two-dimensional pixel arrangement is divided by 2,in length and breadth directions so as to obtain 2,blocks. In the divisional level n=1, four blocks are obtained which are respectively indicated by addresses consisting of 2 bits of 00, 01, 10, 11. In the divisional level n=i, 2,blocks are obtained which are respectively indicated by addresses obtained by adding any two bits of 00, 01, 10, 11 to the low sides of the addresses of 2,blocks of the divisional level n=(i−1). When the controller receives a display signal consisting of a divisional level, an address and a data, a particular block is selected among the plural blocks which are defined by a division of the divisional level. The controller changes a display state of display elements belonging to the particular block to a new state indicated by the data.
