相关申请的交叉引用
本申请要求享有于2016年8月10日提交的名称为“条形显示屏及其拼接式背板”的中国专利申请CN 201610654786.8的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本发明涉及显示技术领域，具体的说，涉及一种条形显示屏及其拼接式背板。
背景技术
随着显示技术的发展，液晶显示屏已经成为最为常见的显示装置。液晶显示屏具有高空间利用率、低功耗、无辐射以及低电磁干扰等优越特性，因此在电视、手机、平板电脑等信息沟通工具中得到广泛使用。
另一方面，随着液晶显示器的应用领域进一步加大，在生活中我们也经常看到一些与普通显示比例(16:9)差异很大的显示屏，此种显示屏通常为长条形，因此被称之为条形显示屏。条形显示屏经常应用在一些公共场所，被当做指示牌，导购牌，信息告示等功能性显示屏使用。
目前的条形显示屏的生产，主要是对普通尺寸比例的液晶显示屏进行切割而获得。如图1所示，在一个普通的液晶显示屏10的一半处或四分之一处进行切割，即可获得两种不同长宽比例的条形屏20、30，以便于应用在适当的场景中。
液晶显示屏是由液晶面板和背板组成的。虽然条形显示屏的液晶面板可以采用上述方法方便的生产制造，但背板具有为液晶面板提供边框的功能，所以简单采用切割的方式不能制造出适合条形显示屏的背板。因此，需要对不同尺寸的条形显示屏的背板进行单独的设计及制造，导致条形显示屏的生产成本较高的技术问题。
发明内容
本发明的目的在于提供一种条形显示屏及其拼接式背板，能够方便的实现条形显示屏的生产制造，以解决现有技术中存在的生产成本较高的技术问题。
本发明提供一种条形显示屏的拼接式背板，包括拼接在一起的底框和顶框，所述底框与所述顶框通过连接件固连；
所述底框上设置有用于放置灯条的凹槽。
优选的是，所述底框和所述顶框通过螺钉与所述连接件相固定。
进一步的是，所述底框的底端设置有支撑壁。
进一步的是，所述顶框的顶端设置有支撑壁。
进一步的是，该拼接式背板还包括一个或多个设置在所述底框与所述顶框之间的独立块，所述独立块上设置有用于放置灯条的凹槽。
优选的是，所述独立块通过所述连接件与所述底框、所述顶框固连。
优选的是，所述独立块通过螺钉与所述连接件相固定。
优选的是，所述连接件呈条形、折线形或弧线形。
本发明还提供一种条形显示屏，包括液晶面板和上述的拼接式背板。
进一步的是，所述液晶面板与所述底框、所述顶框相固定。
本发明带来了以下有益效果：本发明提供的条形显示屏的拼接式背板由底框和顶框拼接而成，并通过连接件将底框与顶框固连，而底框上设置的凹槽可用于放置灯条，为条形显示屏提供背光源。采用本发明提供的技术方案，条形显示屏的背板可以实现拼接组装，能够适用于不同尺寸的条形显示屏。如果条形显示屏的宽度较大，则可以在底框与顶框之间加装适当数量的独立块，组装成合适大小的背板，而不需要对每种尺寸的条形屏都单独设计相应的背板，从而将低了条形显示屏的生产成本，解决了现有技术中存在的生产成本较高的技术问题。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分的从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。

具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
本发明实施例提供一种条形显示屏的拼接式背板，以及使用该拼接式背板的条形显示屏，能够以拼接方式组装条形显示屏的背板，以降低条形显示屏的生产成本。
实施例一：
如图2和图3所示，本发明实施例提供的拼接式背板包括拼接在一起的底框11和顶框12，并且底框11与顶框12通过连接件13固连。本实施例中，底框11和顶框12通过螺钉14与连接件13相固定，以确保底框11、顶框12与连接件13之间的稳定性。
此外，底框11上设置有一凹槽111，凹槽111可用于放置灯条15，从而为条形显示屏提供背光源。也就是由底框11充当背板的主体部分，并提供背光源；顶框12的尺寸较小，只是作为背板的边框与底框11相拼接，以组成完整的背板。而底框11及独立块上凹槽111的数量，也可以根据具体的光源需求进行增加。
进一步的是，底框11的底端设置有支撑壁112，并且顶框12的顶端也设置有支撑壁122。设置在底框11和顶框12上的支撑壁112、122，即作为背板整体的上下两侧的支撑壁，支撑壁112、122可对背板内部的灯条起到保护作用，并且还可用于固定安装液晶面板。
从图2和图3中可以看出，本实施例中的连接件13呈条形。除此之外，在 其他实施方式中，连接件13也可以呈折线形、弧线形，或其他形状，如图4所示。
本发明实施例提供的条形显示屏的拼接式背板由底框11和顶框12拼接而成，并通过连接件13将底框11与顶框12固连，而底框11上设置的凹槽111可用于放置灯条15，为条形显示屏提供背光源。因此，对于宽度较窄的条形显示屏，其背板可以采用本发明实施例中的底框11和顶框12拼接组装而成，从而将低了条形显示屏的生产成本，解决了现有技术中存在的生产成本较高的技术问题。
实施例二：
如图5和图6所示，本发明实施例提供的拼接式背板包括拼接在一起的底框21、顶框22以及两个独立块26，并且底框21、顶框22与独立块26通过连接件23固连。本实施例中，底框21和顶框22通过螺钉24与连接件23相固定，以确保底框21、顶框22与连接件23之间的稳定性。
此外，底框21及独立块26上多设置有凹槽211、261，凹槽211、261可用于放置灯条25，从而为条形显示屏提供背光源。也就是由底框21和独立块26充当背板的主体部分，并提供背光源；顶框22的尺寸较小，只是作为背板的边框与底框21相拼接，以组成完整的背板。而底框21及独立块26上凹槽211、261的数量，也可以根据具体的光源需求进行增加。
进一步的是，底框21的底端设置有支撑壁212，并且顶框22的顶端也设置有支撑壁222。设置在底框21和顶框22上的支撑壁212、222，即作为背板整体的上下两侧的支撑壁，支撑壁212、222可对背板内部的灯条起到保护作用，并且还可用于固定安装液晶面板。
从图5和图6中可以看出，本实施例中的连接件23呈条形。除此之外，在其他实施方式中，连接件23也可以呈折线形、弧线形，或其他形状，如图4所示。
本发明实施例提供的条形显示屏的拼接式背板由底框21、顶框22和独立块26拼接而成，并通过连接件23将底框21、顶框22与独立块26固连，而底框21和独立块26上设置的凹槽211、261可用于放置灯条25，为条形显示屏提供背光源。与实施例一相比，本实施例中提供的拼接式背板适用于宽度更大的条形显示屏，可以根据条形显示屏的宽度，在底框21与顶框22之间增设适当数量的独立块26，使条形显示屏的背板可以由底框21、顶框22和独立块26拼接组装而成， 从而将低了条形显示屏的生产成本，解决了现有技术中存在的生产成本较高的技术问题。
应当说明的是，虽然本实施例中的拼接背板采用了两个独立块，但在其他实施方式中，可以根据条形显示屏的实际尺寸仅采用一个独立块，或者也可采用三个或更多的独立块。
实施例三：
本发明实施例提供一种条形显示屏。
如图7所示，在一种实施方式中，该条形显示屏包括液晶面板和上述实施例一提供的拼接式背板，该拼接式背板由底框11和顶框12通过连接件13拼接组装而成。其中，液晶面板31与底框11、顶框12的支撑壁112、122相固定。
如图8所示，在一种实施方式中，该条形显示屏包括液晶面板和上述实施例一提供的拼接式背板，该拼接式背板由底框21、顶框22和独立块26通过连接件23拼接组装而成。其中，液晶面板32与底框21、顶框22的支撑壁212、222相固定。
本发明实施例提供的条形显示屏与上述实施例提供的拼接式背板具有相同的技术特征，所以也能解决相同的技术问题，达到相同的技术效果。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
