Description

液晶显示器装置 技术领域
本发明涉及显示技术领域,具体涉及一种用以解决发生漏光现象的液晶显示器装置。
 背景技术
液晶显示器装置包括由玻璃基板和其他构件叠成的液晶显示器屏幕,液晶显示器屏幕的上下方分别叠有上偏光片和下偏光片,由数个层次构成的光学膜片通过胶片与下偏光片粘接,光学膜片的另一面依次叠有导光板和反射片。上述结构的四周设有胶框,胶框延伸至光学膜片和反射片之间,并且与反射片粘接。上述光学膜片、导光板、反射片以及胶框等构件构成背光源。
习知的液晶显示器装置通常会有光从胶框与装置中框之间的空间漏出,通过装置中框的侧壁反射,从视窗区出来而造成漏光。因此,不能有很好的视觉效果。特别是当影像必须以全黑显示时,漏光的问题会更加明显。
为防止上述漏光问题而影响显示效果，习知手段有通过在构件间黏贴黑双面胶来解决上述漏光问题。
 技术问题
然而,现今为实现窄边框,甚至极窄边框的显示装置,因机构空间、工艺等限制,已经无法通过常规的贴黑双面胶手段来解决漏光问题。此外,由于黑双面胶是由人工组装黏贴在胶框上,若存在一组装间隙,光仍会从此间隙泄漏出来,使得仍然存在漏光的问题。为了改善漏光的问题,习知技术有提出将胶框结构做成黑色，以黑色胶框的吸光性来解决背光模块周边漏光的问题,但黑色胶框会从侧边吸收导光区边缘的一部分光源,导致背光模块发出来的光亮度偏低,造成发光效率不佳。黑色胶框虽然有效解决来自黑色胶框侧边的漏光问题,却产生背光模块发光效率较低的另一个问题,因此仍然不是解决来自黑色胶框侧边漏光问题的好方法。
如图1所示,为习知的液晶显示器装置,自发光源41发射的光线1从胶框47的侧边透射部分出来,透射出来的光线1通过手机中框10的侧壁反射而经过模块玻璃21的视窗区到手机表面，从侧面进入人眼，造成不良视觉感受。

如图2所示,所述可塑性粘合剂500以配备有高精密喷射阀52的点胶器54,沿着所述触控模块200的下方至所述胶框407上表面的上方之间的液晶显示器模块300的两侧边,包括触控模块200下方的光学透明胶299的两侧边和口字胶303的两侧边以及胶框407上表面的部分面积以点胶方式实施涂覆。
所述喷射阀52为压电式喷射阀或可替代地为气动式喷射阀。
所述可塑性粘合剂500的点胶厚度为0.1-0.5毫米(mm)之间。
如图3所示,为根据本发明较佳实施例所述的涂覆有黑色的可塑性粘合剂500的液晶显示器装置,由于黑色的不透光可塑性粘合剂500对光线有吸收作用,可以有效阻隔来自胶框407所泄漏,并通过手机中框120反射的光线11,因此有效解决来自背光模块400的发光源401的光线11所产生的漏光问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
