Abstract: A pixel structure (1) for an electronic display (2), the pixel structure (1) comprising a substrate (3), at least one LED emitter (4) arranged on the substrate (3), and at least one wavelength conversion unit (5) arranged on the substrate (3) adjacent the LED emitter (4). The LED emitter (4) is configured to emit emission radiation (R1), the emission radiation (R1) being within an emission wavelength range and emitted in one or multiple emission directions (D2,...,Dn) within a main emission plane (P1). The wavelength conversion unit (5) is configured to convert the emission radiation (R1) to converted radiation (R2) within a converted wavelength range, the converted wavelength range being different from the emission wavelength range. The converted radiation (R2) propagates from the wavelength conversion unit in a main conversion direction (D1) perpendicular to the main emission plane (P1), the main conversion direction (D1) being, for example, a direction towards a user of an electronic device having an electronic display comprising at least one such pixel structure. Each pixel structure may comprise six LED emitters (4), a first pair of LED emitters (4) being operably connected to a first wavelength conversion unit (5), a second pair of LED emitters (4) being operably connected to a second wavelength conversion unit (5), and a third pair of LED emitters (5), each LED emitter of said third pair emitting emission radiation directly in the main conversion direction (D1), or being operably connected to a radiation scattering unit 6 or a further wavelength conversion unit 5 each.

Abstract: Die Erfindung betrifft ein Leuchtsystem (10) zur räumlich gleichmäßig verteilten Abstrahlung von Licht aus ersten, zweiten und dritten Lichtquellen (12a – 12c), wobei sich die Spektralbereiche des von den verschiedenen Lichtquellen (12a – 12c) emittierten Lichts voneinander unterscheiden, mit einer Halteschicht bzw. Trägerschicht (14), auf der sich die Lichtquellen (12a – 12c) in Gruppen von jeweils einer der ersten, zweiten und dritten Lichtquellen (12a – 12c) befinden und mit einer Luminophorschicht (20), die in Ausbreitungsrichtung des Lichts aus den Lichtquellen (12a – 12c) angeordnet ist und die eine erste, zweite und dritte Leuchtstofffolie (22a – 22c) aufweist, wobei der Leuchtstoff (24a – 24c) jeder Leuchtstofffolie (22a – 22c) jeweils weitestgehend, insbesondere ausschließlich, durch die ersten, zweiten oder dritten Lichtquellen (12a – 12c) zum Leuchten angeregt wird.

Abstract: L'invention concerne un dispositif d'affichage couleur comportant une matrice de sources de lumière, chaque source de lumière comportant une seule micro-diode électroluminescente, les sources de lumière étant de trois couleurs différentes, chaque pixel coloré (14, 24, 34, 44, 54) de la matrice comportant trois sources émettant dans les trois couleurs différentes. Dans le dispositif selon l'invention, la matrice est constituée d'un ensemble de composants élémentaires (15, 25, 35, 45, 55) de forme identique, chaque composant élémentaire comportant au moins deux diodes électroluminescentes émettant dans une des trois bandes spectrales - la forme des diodes électroluminescentes étant soit un triangle, soit un quadrilatère, soit un pentagone - les composants élémentaires étant assemblés par trois de façon que leurs diodes respectives se touchent par un de leurs côtés, l'ensemble constitué par les trois sources associée aux trois diodes formant un pixel coloré.
