【附图说明】
图1是本发明第一实施例一种显示装置的结构示意图；
图2是本发明第二实施例一种显示装置的结构示意图；
图3是本发明第三实施例一种显示装置的结构示意图。
【具体实施方式】
下面结合附图和实施例，对本发明作进一步的详细描述。以下实施例仅用于说明本发明，但不应用来限定本发明的范围。
请参阅图1，图1是本发明第一实施例一种显示装置的结构示意图。如图1所示，本实施例所揭示的显示装置10包括前框110、背板120、背光模组130以及显示面板140。其中，前框110和背板120组成一个容置空间，用于收容背光模组130和显示面板140。
在本实施例中，背板120包括侧壁121和底部122。背光模组130包括导光板131、光源132以及光学膜片层135。其中，导光板131设置在背板120的底部122上，并且导光板131设置有入光面151和出光面152。光源132设置在背板120的侧壁121上，并与导光板131的入光面151相对设置。光学膜片层135设置在导光板131的出光面152上。本实施例中，在光学膜片层135朝向光源132的端部设置有黑色遮光区123，以防止光源132发出的光线从光学膜片层135的端部进入光学膜片层135内。
在本实施例中，黑色遮光区123设置有黑色涂层125，并且黑色涂层125的高度与光学膜片层135的厚度相同。其中，黑色涂层125的材质包括炭黑、钛黑、金属氧化物、金属硫化物以及有机颜料中的至少一种。因此，光源132发出的部分光线射入到光学膜片层135的端部时被黑色涂层125吸收，从而能够防止光源132发出的光线从光学膜片层135的端部进入光学膜片层135内，进而提高显示装置，尤其是窄边框显示装置的显示品质。
进一步地，显示面板140包括显示区124，并且黑色遮光区123设置在显示区124之外，避免了阻挡由光学膜片层135出射到显示区124的光线，因此保证了显示面板140的显示品质。
本实施例中，背光模组130进一步包括胶框133以及反射片134，胶框133设置在前框110面向显示面板140的一侧，胶框133用于支撑显示面板140并压持光学膜片层135。反射片134设置在背板120的底部122与导光板131之间，用于将光线反射回到导光板131内。
区别于现有技术，本发明实施例在光学膜片层135的黑色遮光123区设置黑色涂层125，通过上述方式，黑色涂层125能够吸收光源132入射到光学膜片层135端部的光线，阻挡光线进入光学膜片层135的内部，从而防止产生漏光的现象，进而提高显示装置，尤其是窄边框显示装置的显示品质。
请参阅图2，图2是本发明第二实施例一种显示装置的结构示意图。如图2所示，本实施例的显示装置20与上述第一实施例的显示装置10的区别在于：本实施例的光学膜片层210的黑色遮光区211中设置有黑色胶带212。其中，黑色胶带212的一端设置在光学膜片层210的顶面上，另一端由顶面沿着光学膜片层210的端部向下延伸至光学膜片层210的底面。
同理，本发明实施例在光学膜片层210的黑色遮光区211中设置黑色胶带212，同样可以防止光源发出的光线从端部进入光学膜片层210内而产生的漏光，进而提高显示装置，尤其是窄边框显示装置的显示品质。
请参阅图3，图3是本发明第三实施例一种显示装置的结构示意图。如图3所示，本实施例的显示装置30与上述第一实施例的显示装置10的区别在于：本实施例的光学膜片层310的黑色遮光区311中设置有黑色涂层312，并且在黑色涂层312上进一步设置有黑色胶带313。其中，黑色胶带313的一端设置在黑色涂层312的顶面上，另一端由黑色涂层312的顶面向下延伸至黑色涂层312的底面。
同理，本发明实施例在光学膜片层310的黑色遮光区311中设置黑色涂层312，并且在黑色涂层312上进一步设置有黑色胶带313，同样可以防止光源发出的光线从端部进入光学膜片层310内而产生的漏光，进而提高显示装置，尤其是窄边框显示装置的显示品质。
综上所述，本发明在光学膜片层的端部设置有黑色遮光区，该黑色遮光区设置有黑色涂层、黑色胶带或在黑色涂层上进一步设置黑色胶带。通过上述方式，能防止光源发出的光线从端部进入光学膜片层内而产生漏光，进而提高显示装置，尤其是窄边框显示装置的显示品质。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
