Description

【技术领域】
本发明涉及液晶显示领域，特别是涉及一种显示器背板以及液晶显示器。
【背景技术】
背光模组是液晶显示器的关键零组件之一，由于液晶本身不具发光特性，因此必须在LCD面板底面加上一个发光源，方能达到饱满的色彩显示效果。背光模组的功能即在于供应亮度充足且分布均匀的平面光源，使LCD能正常显示影像。
显示器背板是背光模组的重要组成部分。显示器背板的主要作用是容纳和保护背光模组的光学组件并为液晶显示器提供所需的机械强度。目前，显示器背板多为一体式，其面积较大，在包装运输时效率不高，导致整体成本上升。
因此需要提供一种液晶显示背板以及液晶显示器，以解决上述问题。

为解决上述技术问题，本发明采用的另一个技术方案是：提供一种液晶显示器，包括一显示器背板。该显示器背板包括两个第一支架和两个第二支架。第一支架呈L形设置，且分别包括呈条状设置的第一架体和第二架体，第二架体垂直连接第一架体。第二支架呈条状设置，该两个第二支架中的一第二支架的两端分别铰接该两个第一支架中的一第一支架的第二架体的自由端以及该两个第一支架中的另一第一支架的第一架体的自由端。该两个第二支架中的另一第二支架的两端分别铰接该两个第一支架中的一第一支架的第一架体的自由端以及该两个第一支架中的另一第一支架的第二架体的自由端，以使得显示器背板在第一状态和第二状态之间进行切换，其中显示器背板在第二状态下的面积小于在第一状态下的面积。

本发明的有益效果是：区别于现有技术的情况，本发明通过L形支架和条形支架拼接形成显示器背板，使得显示器背板可以折叠，能够提高显示器背板的包装和运输效率，并且可以避免显示器背板在运输过程中产生变形。
【附图说明】
图1是本发明显示器背板的优选实施例在第一状态下的结构示意图；
图2是本发明显示器背板的优选实施例在第二状态下的结构示意图；
图3是本发明液晶显示器的结构示意图。
【具体实施方式】
参阅图1和图2，图1是本发明显示器背板的优选实施例在第一状态下的结构示意图，图2是本发明显示器背板的优选实施例在第二状态下的结构示意图。在本实施例中，显示器背板1包括：两个第一支架10、12和两个第二支架11、13。
在本实施例中，两个第一支架10、12均呈L形设置，且第一支架10包括呈条状设置的第一架体101和第二架体102，第二架体102垂直连接第一架体101。类似的，第一支架12包括呈条状设置的第一架体121和第二架体122，第二架体122垂直连接第一架体121。
两个第二支架11、13均呈条状设置，第二支架11的两端分别铰接第一支架10的第二架体102的自由端以及第一支架12的第一架体121的自由端。第二支架13的两端分别铰接第一支架10的第一架体101的自由端以及第一支架12的第二架体122的自由端。
通过上面描述的两个第一支架10、12和两个第二支架11、13的连接方式，显示器背板1可以在图1所示的第一状态和图2所示的第二状态之间进行切换，并且显示器背板1在第二状态下的面积小于在第一状态下的面积。
需要说明的是，在第一状态下，两个第一支架10、12和两个第二支架11、13构成的框架的面积较大，可用作液晶显示器的背光模组的背板，进而容纳和保护背光模组的光学组件，并为液晶显示器提供所需的机械强度。在第二状态下，两个第一支架10、12和两个第二支架所形成的框架的面积较小，收容性更好，因此可在仓储或者运输时折叠为第二状态，进而减小空间和提高效率。此外，由于在第二状态下，显示器背板的受力面积变小，因而还避免了显示器背板在运输过程中产生变形。
值得注意的是，在本实施例中，第二架体102、122的长度优选小于第一架体101、121的长度以及第二支架11、13的长度，因此第二支架11、13在第一状态下垂直于第一架体101、121设置，且在第二状态下平行于第一架体101、121设置或与第一架体101、121沿同一直线设置。此外，第二支架11和13的长度优选大于第二架体102、122，以满足现有液晶显示器的形状要求。在其他实施例中，上述元件的长度可根据实际需要进行任意配置，只需使得显示器背板1能够在不同面积的两个状态下进行切换即可。
在本实施例中，第一支架10、12和第二支架11、13之间优选为通过转钮14、15、16和17进行铰接。在其他实施例中，第一支架10、12和第二支架11、13也可以通过本领域其他公知方式进行铰接。为了实现更好地折叠效果，第二支架11、13与第二架体102、122之间的铰接位置（例如，转钮轴心）到第一架体101、121的内边缘的距离A大于或等于该铰接位置到第二支架11、13的内边缘的距离W。
此外，本发明还提供了一种液晶显示器。参阅图3，图3为本发明的液晶显示器的结构示意图。液晶显示器2包括液晶显示面板20、显示器背板21以及设置于液晶显示面板20与显示器背板21之间的光学组件，例如光源22、导光板23以及光学膜片24等等。显示器背板21可采用上述任一种实施方式所述的显示器背板。
区别于现有技术，本发明通过L形支架和条形支架拼接形成显示器背板，使得显示器背板可以折叠，能够提高显示器背板包装和运输效率并且可以避免显示器背板在运输过程中产生变形。
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。
