Description

显示装置 技术领域
本发明的实施例涉及一种显示装置。 背景技术
从显示面一侧开始， 显示装置一般依次包括前框、 显示屏、 背光模组、 时序控制板、 背板和后盖。
一般的显示装置， 时序控制板安装在背板的上边缘， 现有的时序控制板 和背板的连接方式是采用胶粘， 然后与显示屏连接。 由于采用胶粘的固定方 式不牢固，在搬运和做跌落试验时，时序控制板容易脱离，刮伤覆晶薄膜（筒 称 COF )排线， 造成花屏等不良现象。
为了解决上述问题， 目前有的显示装置的前框包括胶框和铁框， 时序控 制板与背板胶粘后， 显示屏、 背光模组与背板装配后需要通过螺釘固定在铁 框上， 然后整体扣在前框内， 最后合上后盖， 因此， 就需要在铁框的上、 下、 左、 右边缘上预留螺釘的安装孔， 因此， 增加了前框和显示屏的上下边框的 宽度， 进而使得显示屏的显示区域变窄。 发明内容
本发明的实施例提供一种显示装置， 能够防止时序控制板的脱落， 避免 刮伤显示屏而使得显示屏产生亮线， 且能够缩短前框上下边缘的宽度， 增加 显示屏的显示区域面积， 实现超薄显示装置。
本发明的实施例提供一种显示装置， 包括： 时序控制板； 以及背板， 包 括一个主体以及多个边缘， 所述时序控制板采用连接件附接所述背板的边缘 之一， 所述连接件包括卡扣部和与所述卡扣部连接的连接部， 所述卡扣部用 于卡住所述时序控制板， 所述连接部与背板的所述边缘连接。 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 筒单地介绍，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是根据本发明实施例的示例性连接件的沿一个方向的轴测图； 图 2是根据本发明实施例的示例性连接件沿另一个方向的轴测图； 图 3是根据本发明实施例的背板的结构示意图；

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。
下面结合附图和实施例， 对本发明的具体实施方式作进一步详细描述。 以下实施例用于说明本发明， 但不用来限制本发明的范围。
如图 4和图 5所示， 根据本发明实施例的一种显示装置， 包括： 时序控 制板 300和背板 100, 其中， 背板 100包括一个主体以及多个边缘， 时序控 制板 300采用多个连接件 200与背板 100的边缘之一附接， 该连接件 200包 括卡扣部 210和与该卡扣部 210连接的连接部 220, 卡扣部 210用于卡住时 序控制板 300, 连接部 220与背板 100的所述边缘连接。
示例性地， 所述显示装置还包括前框 600、 显示屏 400、 背光模组 500 和后盖 700。
示例性地， 根据本发明实施例的显示屏可以为液晶显示屏。
示例性地， 所述连接部连接到所述背板的下边缘。
示例性地， 图 1-2给出了根据本发明实施例的连接件的两个不同方向的 轴测图， 如图 1-2所示， 卡扣部 210为凹字形， 包括： 一个横段 213; 两个 竖段 211 ,设置在所述横段的两端且与其连接； 以及两个挡块 212,每个设置 在一个竖段的未与所述横段连接的一端， 且该挡块 212与横段 213之间具有 可卡住时序控制板 300的间隙 d。 示例性地， 间隙 d等于所述时序控制板 300的厚度。 所述横段 213的内 长度为 L, L等于或略小于所述时序控制板的宽度， 所述两个挡块 212的端 部沿所述横段的长度方向之间的距离 M小于所述时序控制板的宽度 L,时序 控制板 300被卡扣在挡块 212与卡扣部的横段 213之间， 从而使得时序控制 板 300不脱落。
示例性地， 连接部 220为凸字形， 包括凸起部位 221和主体 222, 其中 连接部的凸起部位 221与卡扣部 210的横段 213背部（该背部指的是 字形 的卡扣部 210的横段的与卡扣部开口方向相反的一侧） 固定； 例如， 该连接 部的凸起部位 221与卡扣部 210的横段 213的背部的中部固定， 即所述凸起 部位 221固定到所述横段 213的长度方向上的中间位置， 以达到更优的牢固 连接作用。
需要注意的是， 连接部 220和卡扣部 210可以形成为一体。
结合图 2、 图 3和图 4, 背板 100的边缘设有卡槽 110, 该卡槽 110用于 卡住连接部 220, 卡槽 110内部的空间的宽度比卡槽 110的开口宽度大。 具 体地， 连接部的横段 222穿过卡槽 110的开口进入卡槽 110内部后经过转动 一定角度， 使得该连接部的横段 222卡在卡槽 110内部。
示例性地， 如图 3所示， 背板 100的下边缘处设置有竖板 120, 连接件 200的连接部 220附接到竖板 120,且时序控制板 300设置在竖板 120的外侧， 且时序控制板 300的长度方向沿着竖板 120的长度方向。 此外， 该竖板 120 中形成有多个卡槽 110, 所述多个卡槽 110沿着所述竖板 120的长度方向均 匀设置且用于卡住所述连接部 220, 并且所述竖板 120可与背板 100下边缘 具有一定倾斜角度设置， 当然也可以如图 3所示， 竖板 120沿水平方向设置 在背板 100下边缘， 或者是背板 100的下边缘具有一定倾斜角度， 再将竖板 120设置其上， 具体设置方式此处不做限定。 可在所述竖板 120上与连接部 220连接的壁面上形成有卡槽 110,或者是在竖板 120上若干位置穿通以形成 若干卡槽 110,且所述卡槽 110的开口形成为能够使得连接部 220的横段 222 进入， 当连接部 220的横段 222可穿过卡槽 110的开口进入卡槽 110内部后 经过转动一定角度， 使得该连接部 220的横段 222卡在卡槽 110的内部。
示例性地， 连接部的凸起部位 221为楔形块， 以方便转动， 以便于安装 和拆卸。 该楔形块截面较小的一端与卡扣部的横段 222连接， 其截面较大的 一端与背板的卡槽 110连接。 连接部 220的一个侧面为斜面， 以便于连接部 插入背板 100中的卡槽 110。
示例性地，该连接部 220与背板 100的下边缘连接，背板 100和前框 600 的上边缘不需要预留螺丝安装位置。 前框 600为例如胶框， 不再采用铁框对 背板和显示屏进行固定。显示屏 400、背光模组 500和安装有时序控制板 300 的背板 100扣在胶框内， 最后再扣上后盖 700, 只需要在背板 100和胶框的 下边缘、 左边缘和右边缘预留螺纹孔， 通过螺釘将背板 100和胶框连接， 背 板 100和胶框的上边缘只需扣合在一起即可， 而下边缘的时序控制板 300采 用扣合的连接方式已经可以保证背板 100和时序控制板 300的可靠连接， 只 需在下边缘预留较小宽度的螺纹孔来进行与胶框的连接， 该结构尤其适用于 直下式一体机。
需要指出的是， 卡扣部 210还可以为两端开口的管状， 安装时， 将时序 控制板穿入即可。 需要指出的是， 连接部 220的截面还可以为蝶形、 十字形 等； 此外， 连接部 220和卡槽 110还可以设计为快速插拔的连接结构， 如， 将连接部设置为连接杆形状， 在该连接杆上安装可伸缩的凸台， 并在卡槽内 相应的位置设有与凸台相匹配的搭接槽，连接杆内设有控制凸台伸缩的机构， 类似于伞骨， 连接杆插入卡槽内， 凸台卡在搭接槽内， 使得连接杆与卡槽连 接。
示例性地， 多个连接件均匀地设置于时序控制板的长度方向上。 例如， 连接件 200为五个。 需要指出的是， 该连接件 200的个数不限， 是根据时序 控制板的长度而定， 以确保时序控制板连接牢固为依据。
上述显示装置可以为： 液晶显示器、 电子纸、 有机发光二极管显示器 ( OLED ) 、 液晶电视、 数码相框、 手机、 平板电脑等任何具有显示功能的 产品或部件。
本发明的实施例所提供的一种显示装置， 其中时序控制板和背板的边缘 采用卡扣的连接方式， 使其连接牢固， 可避免由搬运或跌落试验等引起的振 动时造成时序控制板脱离的问题， 避免刮伤显示屏而使得显示屏产生亮线。 进一步地， 时序控制板放置在背板的下边缘， 背板和前框的上边缘不需要预 留螺丝安装位置， 可以缩短前框上下边缘的宽度， 从而增加了显示屏的显示 区域， 达到视觉上超薄的效果。 而且， 时序控制板可通过竖板设置在背板的 下边缘， 时序控制板设置在竖板的外侧， 并且竖板可具有一定的倾斜角度， 此时时序控制板设置于竖板上后可对其进行支撑， 时序控制板也与背板所在 平面具有一定倾斜角度， 形成位于背板下边缘的倒放结构， 使得即使时序控 制板脱落也不会刮伤显示屏。本发明实施例的显示装置的结构和性能较稳定。
以上所述仅是本发明的实施例， 应当指出， 对于本技术领域的普通技术 人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换， 这些改进和替换也应视为本发明实施例的保护范围。
