Abstract
(EN) A backlight module, and a display device comprising the backlight module. The backlight module comprises at least one optical film (2) and a backlight unit (3). The optical film (2) has a light-incident side (21) and a light-exit side (22) opposite to the light-incident side (21), a plurality of light-incident microstructures (24) being formed on the light-incident side (21), and the light-incident microstructures (24) being of a pyramid structure. The backlight unit (3) is arranged on the light-incident side (21) of the optical film (2) and comprises a light source (31). By means of the structural design of the light-incident microstructures (24) of the optical film (2), a light field of the light source (31) can be further expanded to achieve the purpose of emitting light at a specific angle.
(FR) L’invention concerne un module de rétroéclairage et un dispositif d’affichage comprenant le module de rétroéclairage. Le module de rétroéclairage comprend au moins un film optique (2) et une unité de rétroéclairage (3). Le film optique (2) présente un côté d'incidence de la lumière (21) et un côté de sortie de lumière (22) opposé au côté d'incidence de lumière (21), une pluralité de microstructures d'incidence de lumière (24) étant formées sur le côté d'incidence de lumière (21), et les microstructures d'incidence de lumière (24) étant d'une structure pyramidale. L'unité de rétroéclairage (3) est disposée sur le côté d'incidence de lumière (21) du film optique (2) et comprend une source de lumière (31). Au moyen de la conception structurale des microstructures d'incidence de lumière (24) du film optique (2), un champ lumineux de la source de lumière (31) peut être davantage étendu pour obtenir l'objectif d'émission de lumière à un angle spécifique.
(ZH) 一种背光模组及包含背光模组的显示装置,背光模组包含至少一个光学膜片(2)及背光单元(3)。光学膜片(2)具有入光侧(21)及与入光侧(21)相对的出光侧(22),入光侧(21)上形成有多个入光微结构(24),入光微结构(24)是锥状结构。背光单元(3)设置于光学膜片(2)的入光侧(21),并包括光源(31)。通过光学膜片(2)的入光微结构(24)的结构设计,能使光源(31)的光场更为展开,以达成特定角度出光的目的。
