Abstract
A display apparatus having a matrix (4) of semiconductor parts (42) acting both as memories and as amplifiers, and which is driven by two grids of electrodes that are parallel respectively to the lines (L) and to the columns (C) of the matrix (4). Actuation means (6, 7, 8) permits one line of the matrix to be selectively actuated to receive the information to be entered in each part on that line. Electrical signal from each semiconductor part (42) of the given line represents the information that is stored and that signal is displayed in an electroluminescent layer of diodes (3) in the apparatus. The apparatus may be used to display television images.
