Abstract:
1. A display apparatus comprising: a plurality of electrochemical display elements arranged in a matrix comprising a plurality of rows and a plurality of columns; and a control section to apply voltage to each electrochemical display element to attain a desired display density so as to display a desired image by the plurality of display elements, the control section comprising: an assigning section to divide the electrochemical display elements into at least two groups and to assign a starting frame number to each of the electrochemical display elements so that all electrochemical display elements in a same group have a same starting frame number, the display elements in each group being distributed among the rows and columns of the matrix; a voltage application control section to start, during a first frame period, application of the voltage to each electrochemical display element to which a first starting frame number has been assigned and, thereafter, to start, during a second frame period, application of the voltage to each electrochemical display element to which a second starting frame number has been assigned; and a frame administration section to cause the voltage application control section to administer voltage to at least some of the electrochemical display elements in the at least two groups during a number of frame periods succeeding the first frame period until all electrochemical display elements in the at least two groups have attained the desired display density.
