Japanese Patent JP3272732
Kind Code:
B2
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<2n> 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<2i> 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<2(i-1)> 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.
