Title (EN) BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) MODULE DE RÉTROÉCLAIRAGE ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 背光模组及液晶显示装置
Abstract:
(EN) A backlight module and liquid crystal display device. The backlight module (100) comprises: a light source (101), a light guiding plate (102), a reflection sheet (103), and an optical film (104). The light guiding plate (102) comprises a light entry surface (112), a light exit surface (122), and a bottom surface (132). The light entry surface (112) and the light source (101) are arranged to face one another. The light exit surface (122) is in contact with the light entry surface (112). The bottom surface (132) and the light exit surface (122) are arranged to face one another. The optical film (104) is disposed above the light exit surface (122) of the light guiding plate (102). The reflection sheet (103) is disposed below the bottom surface (132) of the light guiding plate (102). Disposed on the reflection sheet (103) is a pigment coating (105) having a gradually changing pigment, the pigment coating (105) being a coating that gradually changes from yellow to blue. The method ensures that the color of the light emitted by the backlight module is consistent, thereby reducing color difference.
(FR) Ce module de rétroéclairage et ce dispositif d'afficheur à cristaux liquides (100) comprennent : une source lumineuse (101), une plaque de guide optique (102), une plaque réfléchissante (103) et un film optique (104). L'invention est caractérisée en ce que la plaque de guide optique (102) comprend une surface d'incidence (112), une surface électroluminescente (122) et une surface inférieure (132). La surface d'incidence (112) et la source lumineuse (101) sont disposées en regard, la surface électroluminescente (122) et la surface d'incidence (112) sont en contact, et la surface inférieure (132) et la surface électroluminescente (122) sont disposées en regard. Quant au film optique (104), il est placé sur la surface électroluminescente (122) de la plaque de guide optique (102), alors que la plaque réfléchissante (103) se trouve sous la surface inférieure (132) de la plaque de guide optique (102). Un revêtement de pigment à dégradé de couleur (105), assurant le passage progressif de la lumière jaune au bleu, recouvre la plaque réfléchissante (103). Selon ce mode, il est possible d'assurer l'émission uniforme de couleur du module de rétroéclairage, d'où une aberration chromatique réduite.
(ZH) 一种背光模组及液晶显示装置,该背光模组(100)包括:光源(101)、导光板(102)、反射片(103)以及光学膜片(104)。其中,导光板(102)包括入光面(112)、出光面(122)以及底面(132),入光面(112)与光源(101)相对设置,出光面(122)与入光面(112)相接,底面(132)与出光面(122)相对设置;光学膜片(104)设置于导光板(102)的出光面(122)的上方,反射片(103)设置于导光板(102)的底面(132)的下方。在反射片(103)上设置一颜色渐变的颜料涂层(105),颜料涂层(105)为一黄光渐变到蓝色的涂层。通过上述方式,能够保证背光模组出射光的颜色一致,从而减小色差。
