ABSTRACT OF THE DISCLOSURE The material of the matrix display is placed between a first group of p parallel electrode rows and a second group of q parallel electrode columns, the rows and columns crossing one another. An area ij of the material is defined by the region of the material covered by row i, in which i is an integer such that l ? i ? p, and by the column j, in which j is an integer such that l ? j ? q, the rows and columns being used for carrying signals bringing about an excitation of the material. The electrode columns have n horizontal gaps defining n + l identical sets of electrode columns; a signal I is applied to electrode row i, whilst a zero signal is applied to the other electrode rows; the signal I is sequentially applied to the p electrode rows in accordance with increasing values of i, a signal J is applied to the electrode columns, the signal J being simultaneously applied to the electrode columns of the first set, during the application time of signal I to the first p/n + l electrode rows, the electrode columns of the other sets receiving a zero signal, then, the electrode columns of the second set during the application time of signal I to the following p/n + l electrode rows; the electrode columns of the first set and other sets receive a zero signal and so on up to the excitation of the electrode columns of the (n + l)th set.
