Abrégé
(EN) A flat source of light, comprising a periodic array of red, green and blue EL elements (100R, 100G, 100B) with an optical resonator structure on a glass substrate (103), is provided on the back of an optical modulation panel (101) including no color filter. The optical modulation panel (101) modulates light from each of the EL elements (100R, 100G, 100B) to form color images.
(FR) Source plate de lumière, comportant un ensemble périodique d'éléments électroluminescents rouges, verts et bleus (100R, 100G, 100B) doté d'une structure de résonateur optique sur un substrat (103) en verre, qui est placée à l'arrière d'un panneau de modulation optique (101) ne comportant pas de filtre coloré. Le panneau de modulation optique (101) module la lumière provenant de chacun des éléments électroluminescents (100R, 100G, 100B) pour former des images en couleur.
