Description

支撑框、显示装置及其装配方法 技术领域
本发明的实施例涉及一种支撑框、显示装置及其装配方法。
背景技术
随着液晶显示技术的发展，用户对产品的性能和用户体验也提出了越来越高的要求。其中一个重要的方面就是窄边框。窄边框可以有效提升显示面积，用户在观看体验时，视野会更广；同时窄边框也降低了大屏手机的宽度，有利于解决单手握持和操作的难题。
窄边框手机一般是指液晶显示屏有效显示区与机身边框间距较窄的手机。在目前的手机模组中，手机中框、背光模组、液晶显示屏是分离的；背光模组一般由背光模块和胶框组成，该胶框放置在手机中框中，用于对背光模块进行支撑。但是，这样的设计不利于显示装置的窄边化。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。
图1为一种显示装置的边框的结构示意图；
图2为本发明一实施例提供的一种包含支撑框的显示装置的结构示意图；
图3为本发明一实施例提供的另一种包含支撑框的显示装置的结构示意图；
图4至图6为本发明一实施例提供的显示装置的装配方法中部分步骤的示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1，为一种显示装置的边框的结构示意图；包括：中框100、胶框200、背光模块300、显示面板400和触控盖板500；胶框200设置在中框100的内侧，用于支撑背光模块300和显示面板400；中框100则用于支撑触控盖板500；其中，d1是显示面板400的显示区域到该显示面板400的边缘的距离，d2是显示面板400到胶框200的边缘的距离，d3是胶框200到中框100的距离(例如为最小距离)，d4是触控盖板500与中框100彼此粘接的宽度，d5是触控盖板500到中框100的距离(例如为最小距离)，d6是中框100上部的厚度。
如图1所示，边框的宽度(即非显示区域的宽度)为d1+d2+d3+d4+d5+d6，该边框宽度较大。
为了解决上述边框宽度较大的问题，本发明的实施例提供了一种支撑框，如图2所示，支撑框100'包括：主体110以及设置在主体110一侧的凸起120，主体110包括在凸起120上方的第一部分1101和在凸起120下方的第二部分1102，第一部分1101的厚度至少等于触控盖板500的厚度，该主体110能够用于承载该触控盖板500的端部。第二部分1102的厚度至少等于背光模块300的厚度，能够使得该支撑框100'在凸起120下方的部分容纳该背光模块300的端部。凸起120的厚度至少等于显示面板400的厚度，凸起120的厚度(这里凸起120的厚度是指主体110的第一部分1101的下表面和主体110的第二部分1102的下表面之间的竖直距离)至少等于显示面板400的厚度，能够使得该支撑框100'在凸起120内侧的区域容纳该显示面板400。
例如，位于凸起120下方的主体110的厚度大于在凸起120上方的主体110的厚度，即主体110的第二部分1102的厚度大于第一部分1101的厚度。
例如，触控盖板500与主体110的第一部分1101之间的距离为二者应间隔的最小距离d5。
例如，背光模块300与主体110的第二部分1102之间的距离为二者应间隔的最小距离d3'。
例如，第二部分的宽度大于第一部分的宽度，这样可以降低在搬运支撑框时凸起120断裂的风险。从图2中可以看出d3'小于d5。
例如，触控盖板500的端面与背光模块300的端面对齐。
由于在本发明实施例提供的支撑框100'的凸起120的下方可以容纳背光模块300，这样无需设置用于支撑背光模块300的胶框。这样相应的显示装置的边框的宽度可以仅为d1+d'+d4+d5+d6；其中d'为显示面板400到支撑框100'的凸起120的边缘的距离。由于d'小于图1中的d2+d3的宽度，从而能够降低边框的宽度。
在本发明的实施例中，主体110在凸起120下方的第一部分1101的厚度大于在凸起120上方的第二部分1102的厚度，能够使得支撑框100'的强度更大，从而能够更好的支撑所需要支撑的重量。
在本发明的实施例中，背光模块300的端部可以伸入到凸起120的下方，因此能够降低边框的厚度，凸起120的高度(即沿水平方向上延伸的 距离)可根据实际应用而设定。
可以理解的是，在实际应用中，支撑框100'一般为环形，相应地，主体110和凸起120也各自为一个环形。环形例如为矩形环。
本发明的实施例还提供一种显示装置，该显示装置的结构也可以参考图2，除了上述的支撑框100'之外，该显示装置还包括：背光模块300、显示面板400和触控盖板500；触控盖板500的端部设置在凸起120的上方且与主体110的第一部分1101相对设置，例如触控盖板500的端面与第一部分1101的侧面相对；背光模块300的端部设置在凸起120的下方且与主体110的第二部分1102相对设置，例如背光模块300的端面与第二部分1102的侧面相对；显示面板400设置在凸起120背离主体110的一侧。
例如，背光模块300可以包括导光板310以及贴附在导光板310上的扩散膜320、第一棱镜膜3301和第二棱镜膜3302。在其他实施例中，上述的导光板310上也可以贴附其他的光学膜层。这里，主体110的第二部分1102的厚度与导光板310以及贴附在导光板310之上的光学膜层的厚度的总和一致。
例如，背光模块300可以通过遮光胶600粘结在支撑框100'的凸起120的下表面上。
例如，触控盖板500通过遮光胶600固定在凸起120的上表面上。
例如，凸起120的厚度至少与显示面板400的厚度相等。例如，凸起120的厚度大于显示面板400的厚度，并且凸起120的厚度和遮光胶600的厚度之和与显示面板400与光学透明胶900的厚度之和相等。光学透明胶900用于粘结触控盖板500和显示面板400。
例如，显示面板400从上到下依次包括上偏光片、上基板、下基板和下偏光片。本领域技术人员可以理解，出于简化目的，图中未详细描绘显示面板中的常规部件或层，例如液晶层。
例如，参见图2，该显示装置还可以包括支撑板700，该支撑板700固定在支撑框100'的主体120的下表面上，该背光模块300设置在支撑板700的上方。通过这种方式，能够避免背光模块300从支撑框100'上脱落。
例如，支撑板700的上表面可以为反射面，这样该支撑板700可以同时实现对光线的反射，可以避免在导光板310的下方单独的设置一个反射层。
例如，支撑板700可以通过粘结的方式(例如通过图2中所示的遮光胶600)固定在主体120的下表面上；或者也可以如图3所示的通过螺钉800固定在主体120的下表面上。当然在实际的应用中，也可以通过其他方式比如卡扣的方式进行固定。
参见图2和图3，在本发明实施例提供的显示装置中，背光模块300的端面和触控盖板500的端面可以齐平。
例如，背光模块300和显示面板400可以通过光学透明胶900连接在一起，并且，显示面板400和触控盖板500也可以通过光学透明胶900连接在一起。这样既能够增加整个显示装置的牢固程度，还可以避免其中的结构分散。
例如，该显示装置可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明的实施例还提供了一种显示装置的装配方法，可以用于装配图2或图3中的显示装置，参见图4-图6，该方法可以包括：
步骤S1，提供触控盖板500、显示面板400、背光模块300和支撑框100'；
步骤S2，参见图4，将触控盖板500和显示面板400通过例如光学透明胶900连接在一起；其中，触控盖板500的端部伸出与显示面板400对应的区域；
步骤S3，参见图5，将触控盖板500的端部通过遮光胶600固定在支撑框100'的凸起120的上表面；
步骤S4，参见图6，将背光模块300的端部通过遮光胶600固定在支撑框100'的凸起120的下表面。
在步骤S4之后，可以通过遮光胶600将支撑板700固定在主体120的下表面，得到如图2所示的显示装置；也可以通过螺钉800将支撑板700固定在主体120的下表面，得到如图3所示的显示装置。
上述方法也可以用于装配其他结构的显示装置，在步骤S3中也可以通过其他方式将触控盖板500的端部固定在支撑框100'的凸起120的上表面，在步骤S4中，可以通过其他方式将背光模块300的端部固定在支撑框100'的凸起120的下表面。
显然，本领域的技术人员可以对本发明进行各种改动或变型而不脱离 本发明的精神和范围。如果这些修改或变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动或变型在内。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2016年1月6日递交的中国专利申请第201610009042.0号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
