Title (EN) FRONT LIT REFLECTIVE DISPLAY
(FR) AFFICHEUR RÉFLÉCHISSANT ÉCLAIRÉ PAR L'AVANT
Abstract:
(EN) A display is described that comprises an array of reflective pixels, a front lighting film made in a transparent material and having a first surface and a second surface; a plurality of solid state light sources such as light emitting diodes (5) on the first surface of the front lighting film; wherein the second surface of the front lighting film is positioned parallel and adjacent to the array of reflective pixels. The plurality of solid state light sources such as light emitting diodes on the first surface of the front lighting film are arranged to illuminate the array of reflective pixels and are substantially co-extensive therewith.
(FR) L'invention concerne un afficheur qui comprend une matrice de pixels réfléchissants, un film d'éclairage par l'avant réalisé dans un matériau transparent et ayant une première surface et une seconde surface ; une pluralité de sources de lumière à semi-conducteurs telles que des diodes électroluminescentes (5) sur la première surface du film d'éclairage par l'avant ; la seconde surface du film d'éclairage par l'avant étant positionnée de façon parallèle et adjacente à la matrice de pixels réfléchissants. La pluralité de sources de lumière à semi-conducteurs telles que des diodes électroluminescentes sur la première surface du film d'éclairage par l'avant sont agencées de manière à éclairer la matrice de pixels réfléchissants et sont sensiblement en co-extension avec cette dernière.
