ABSTRACT:
An electroluminescent matrix screen comprising nm light emitting cells disposed in the form of a matrix of n lines and m columns. Each cell (c.sub.e) is constituted by a two line by two column submatrix having four light emitting elements (el.sub.1 to el.sub.4) selected from three different base colors, such that each cell (c.sub.e) includes two elements (el.sub.1 to el.sub.4) which emit light of the same color. In addition, the areas of the various elements are chosen so that each cell provides, overall, three sources of different colored light having similar luminance. The invention also provides a method of manufacturing a trichromatic electroluminescent matrix screen.
