Title
(EN) REGULAR PATTERN OPTICAL SHEET
(FR) FEUILLE OPTIQUE À MOTIFS RÉGULIERS
Abstract
(EN)
The present invention relates to a regular pattern optical sheet, comprising: a transparent flat plate-shaped body; and a plurality of lens-shaped patterns regularly formed at one surface of the body, each having a same size of more than 0.1μm but smaller than 25 μm in diameter, wherein an angle formed by at least one line of lines straightly connecting each center of the plurality of lens-shaped patterns and a horizontal axis of an LCD pixel formed at an upper surface of the body is more than 5.5˚ but smaller than 9.5˚, and a discrete distance between the plurality of lens-shaped patterns is more than 5% but smaller than 15% of a diameter of the lens-shaped pattern, whereby a high luminance characteristic can be accomplished over the conventional irregular lens pattern arrangement to the betterment of power consumption and environment friendliness. Furthermore, characteristic adjustment is enabled by regular pattern application capable of optical control to cater to various requirements of a user without occurrence of Moire pattern beating.

La présente invention concerne une feuille optique à motifs réguliers, comprenant: un corps en forme de plaque plate transparente; et une pluralité de motifs lenticulaires formés régulièrement sur une surface du corps, chaque motif présentant une même taille supérieure à 0,1 μm mais inférieure à 25 μm de diamètre, un angle formé par au moins une ligne de lignes reliant directement chaque centre de la pluralité de motifs lenticulaires et un axe horizontal d'un pixel LCD formé sur une surface supérieure du corps est supérieur à 5,5° mais inférieur à 9,5°, et une distance distincte entre la pluralité de motifs lenticulaires est supérieure à 5% mais inférieure à 15% d'un diamètre du motif lenticulaire, une caractéristique de luminance élevée pouvant ainsi être atteinte par rapport à l'agencement de motifs lenticulaires irrégulier classique pour améliorer la consommation d'énergie et le respect de l'environnement. En outre, l'ajustement de caractéristiques est permis de par l'utilisation de motifs réguliers permettant la commande optique pour répondre à diverses exigences d'un utilisateur sans apparition de battement de moirage.
