Description

显示装置 技术领域
本发明涉及显示领域，特别是一种显示装置。
 背景技术
随着显示装置的发展，人们对显示装置的外观要求也越来越高，窄边框以及无边框显示装置相对于宽边框显示装置更加美观且拥有更佳的视觉效果，已经成为现有显示装置中的主流。但市面上的无边框显示器其实并非真正意义上的完全没有边框，只是将显示器的边框做的非常小和窄，这样人眼在远距离就没法感觉到边框的存在，从而达到无边框的效果。
在车载显示装置的领域中，人们对车载显示装置的外观要求也越来越高，其中对于车载显示模组边框的要求也越来越窄。现阶段车载显示装置通常是中胶框或者中钣金将底钣金和光学膜片以及灯条等包在内部的设计。由于车载显示的可靠性要求相对比较严苛，市场上通常的模组设计受到结构限制，窄边框设计或无边框设计会存在显示装置的边缘漏光以及显示面板与背光模组可靠性试验后剥离等问题。
 技术问题
本发明的目的是提供一种显示装置，以解决现有技术中窄边框设计或无边框设计中存在边缘漏光以及显示面板与背光模组可靠性试验后剥离等问题。
 技术解决方案
为实现上述目的，本发明提供一种显示装置，所述显示装置包括背光模组、胶框以及钣金。所述背光模组具有出光面和垂直于所述出光面的侧面。所述胶框封装于所述背光模组的侧面，在所述背光模组的侧面，所述胶框具有一开槽。所述钣金包括底板部和垂直于所述底板部的弯折部，所述底板部设于所述背光模组远离所述出光面的一面，所述弯折部弯折至所述背光模组的一侧面且对应的卡接于所述胶框的开槽中。
进一步地，所述弯折部与所述开槽之间存在缝隙。所述显示装置还包括遮光层，贴附在位于所述背光模组的侧面的胶框和钣金的弯折部上，且完全遮盖所述缝隙。
进一步地，所述弯折部的形状契合于所述开槽。
进一步地，所述开槽为“T”形。
进一步地，所述显示装置还包括显示面板，设于所述背光模组的出光面的一侧。
进一步地，所述胶框密封于所述背光模组和所述显示面板之间，且从所述背光模组和所述显示面板之间弯折至所述背光模组的侧面。
进一步地，所述显示装置还包括粘贴层，设于所述显示面板与所述胶框之间。
进一步地，所述底板部的弯折部的厚度小于或等于所述胶框的厚度。
进一步地，所述背光模组包括导光板、反射片以及光学膜片。所述反射片设于远离所述出光面的一侧，且位于所述导光板和所述钣金之间。所述光学膜片设于所述导光板远离所述反射片的一面上。
进一步地，所述反射片从所述远离所述出光面弯折至所述背光模组的侧面。
 有益效果
本发明的优点是：本发明的一种显示装置，通过将其钣金的弯折部与其中框的开槽卡合，将所述胶框固定在所述钣金上，确保所述显示装置的基本架构稳定。在实现了胶框的结构功能的同时不增加所述胶框的厚度，还相对于现有设计中少了一层胶框或钣金的厚度，从而达到减少模组边框的目的。并且还通过设置遮光层解决了现有技术中边缘漏光的问题。

本发明实施例中提供一种显示装置100。如图1所示，所述显示装置100包括一背光模组20、一胶框30、一钣金40以及一显示面板10。
所述背光模组20具有一出光面以及侧面，所述侧面垂直于所述出光面。所述背光模组20用于为所述显示面板10提供光源，所述光源通过所述出光面射出。所述显示面板10设于所述背光模组20的出光面的一侧。所述显示面板10为液晶显示面板10（Liquid Crystal Display,LCD），用于显示画面。所述液晶显示面板10是一种采用液晶为材料的显示器。液晶是介于固态和液态间的特殊物质，它是一种有机化合物，常态下呈液态，但是它的分子排列却和固体晶体一样非常规则，因此取名液晶，它的另一个特殊性质在于，在电场作用下，液晶分子会发生排列上的变化，从而影响通过其的光线变化，这种光线的变化通过偏光片的作用可以表现为明暗的变化。就这样，人们通过对电场的控制最终控制了光线的明暗变化，从而达到显示图像的目的。如果再配合彩色滤光片，改变加给液晶电压大小，就能改变某一颜色透光量的多少，也可以形象地说改变液晶两端的电压就能改变它的透光度。
所述背光模组20是位于所述液晶显示面板10下的一种光源，它的发光效果将直接影响到所述液晶显示面板10视觉效果。所述液晶显示面板10是被动发光元件，其本身并不发光，它显示的画面或图像是它对其下方的背光模组20所提供的光线调制后的结果。所述背光模组20和所述液晶显示面板10组合在一起构成了液晶显示模块。
所述背光模组20包括导光板21、反射片22、光学膜片23以及一光源（图未示）。所述反射片22设于远离所述背光模组20出光面的一侧，并且所述反射片22从所述远离所述出光面弯折至所述背光模组20的侧面。所述导光板21设于所述反射片22上。所述光学膜片23设于所述导光板21远离所述反射片22的一面上。所述光源设于所述背光模组20的一侧或两侧。
所述背光模组20是一个平面的均匀照明装置，所述光源排列在整个背光模组20的一侧或两侧。所述光源一般为冷阴极荧光灯管（Cold Cathode Fluorescent Lamp，CCFL）或发光二极管（Light Emitting Diode，LED）灯条，冷阴极荧光灯管是线光源，发光二极管灯条是点光源，因此把线光源和点光源转换为面光源需要使用导光板21。所述导光板21是利用射出成型的方法将丙烯压制成表面光滑的板块，然后用具有高反射且不吸光的材料，在导光板21的底面用网版印刷的方式印上扩散点，冷阴极荧光灯管或发光二极管灯条位于导光板21侧边，其发出的光利用反射导入导光板21内部，当光线射到扩散点时，反射光会往各个角度扩散，然后将破坏反射条件由导光板21正面射出。利用各种疏密、大小不一的扩散点，可使导光板21均匀发光。所述反射片22的用途在于将射向底面的光线反射回所述导光板21中，用来提高光的使用效率。所述导光板21和所述反射片22用于引导光的散射及反射方向，促使光线不会从所述出光面以外的区域射出，提高所述背光模组20的亮度，并确保所述显示面板10亮度的均匀性。所述导光板21上会再放置光学膜片23，所述光学膜片23中一般包括棱镜片、扩散片、增亮片等膜片，这些膜片起到提高所述背光模组20的正视亮度，或称轴向亮度，在不增加光源数量的情况下，改善光线的角分布，将光线集中到正视角度上，并减少损耗，提高总的出光光通量。
所述胶框30密封装于所述背光模组20和所述显示面板10之间，且从所述背光模组20和所述显示面板10之间弯折至所述背光模组20的侧面，所述显示面板10通过一粘贴层60固定于所述胶框30上。并且在所述背光模组20的侧面，所述胶框30具有一开槽31，如图2所示，所述开槽31为“T”形。所述胶框30用于保护所述背光模组20和所述显示面板10，避免在生产、运输移动过程中，所述背光模组20和所述显示面板10因发生挤压或磕碰而受到损坏。
所述钣金40包括底板部42以及垂直于所述底板部42的弯折部41。其中，所述底板部42设于所述背光模组20远离所述出光面的一面，如图2所示，所述弯折部41弯折至所述背光模组20的一侧面且对应的卡接于所述胶框30的“T”形开槽31中，并且所述弯折部41的形状契合于所述开槽31，所述弯折部41的厚度小于或等于所述开槽31的厚度。所述钣金40用于保护所述背光模组20，并且其通过所述弯折部41与所述开槽31的卡接，确保了所述背光模组20的基本架构的稳定，稳固所述显示装置100的整体结构。
在本发明的其他实施例中，所述开槽31还可以为“┌”形、“┐”形、“F”形等其他同样具有卡合固定作用的形状。并且，在其他实施例中的显示装置100的层状结构与开槽31为“T”形的显示装置100相似，因此不在此做过多赘述。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本申请保护的范围。
所述显示装置100还包括一遮光层50，由于所述弯折部41与所述开槽31之间存在缝隙，所述遮光层50贴附在位于所述背光模组20的侧面的胶框30和钣金40的弯折部41上，且完全遮盖所述缝隙，避免外界异物的进入以及缝隙的漏光。
本实施例中的所述显示装置100具有窄边框设计效果，其可以为手机、平板电脑、笔记本电脑、数码相机、导航仪等任何具有显示功能的产品或者部件。
本发明实施例中提供的一种显示装置100，其通过将钣金40的弯折部41与其中框的开槽31卡合，将所述胶框30固定在所述钣金40上，所述钣金40的弯折部41在竖直方向上支撑所述胶框30，确保所述背光模组20的基本架构稳定。同时，在保证了所述胶框30功能的前提下，水平方向上所述胶框30侧面与所述钣金40的弯折部41处于同一竖直面，在实现了胶框30的结构功能的同时不增加所述胶框30的厚度，并且还相对于现有的胶框侧壁与钣金侧壁叠加的设计中减少了一层胶框或钣金的厚度，从而达到减少模组边框的目的。并且还通过设置遮光层50解决了现有技术中边缘漏光的问题。
虽然在本文中参照了特定的实施方式来描述本发明，但是应该理解的是，这些实施例仅仅是本发明的原理和应用的示例。因此应该理解的是，可以对示例性的实施例进行许多修改，并且可以设计出其他的布置，只要不偏离所附权利要求所限定的本发明的精神和范围。应该理解的是，可以通过不同于原始权利要求所描述的方式来结合不同的从属权利要求和本文中所述的特征。还可以理解的是，结合单独实施例所描述的特征可以使用在其他所述实施例中。
