Description

一种液晶显示装置的制作方法和液晶显示装置
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种液晶显示装置的制作方 法和液晶显示装置。
【背景技术】
液晶显示装置包括前框、 背板， 前框在液晶显示装置的最外层， 而背板位 于装置的背部， 用于承托液晶显示装置的背光模组内部的器件， 并与前框配合， 形成整个液晶显示装置的外壳， 液晶显示装置的内部一般还设有胶框， 用于隔 离背光模组和液晶面板。 现行量产的液晶显示装置通常会用前框固定面板
( panel ), 多采用一体式设计 (如图 1-2)或支架式（如图 3-4 )设计， 此两种设计 均需要单独开发模具。
如图 5-6所示， 现有的一种液晶显示装置包括一种金属前框 10, 金属前框 跟液晶面板 40之间设有柔性垫片 13 , 液晶面板 40和导光板 50之间设有胶框 20,胶框 20跟液晶面板 40的接触面也设有柔性垫片 13 ,金属前框 10、胶框 20、 背板 30在液晶显示装置的侧面进行固定。
上述现有的液晶显示装置存在至少两个问题： 1.前框的模具费用较高； 2. 材料费及人力成本较高。
【发明内容】
本发明所要解决的技术问题是提供一种低成本的液晶显示装置的制作方法 和液晶显示装置。
本发明的目的是通过以下技术方案来实现的：
一种液晶显示装置的制作方法， 包括前框和胶框的制作方法：
A: 在同一模具中设计出板状的前框图形和胶框图形；
B: 在所述模具中注塑， 脱模后形成所述前框和胶框。 优选的， 所述前框图形包括四条独立的子前框图形， 以及四条子前框首尾 连接形成的矩形前框的拼接结构图形。 采用子前框拼接的方式， 可以筒化前框 结构， 出模的时候可以单条子前框分别取出， 降低了出模的难度。
优选的， 所述胶框图形为一体成型的图形结构。 一体成型的胶框图形可以 筒化后续前框的安装步骤， 并且前框连接强度也比较高。
一种液晶显示装置， 包括前框和胶框， 所述前框和胶框之间夹持有液晶面 板， 所述液晶面板在与其出光面的平行方向由胶框固定、 与其出光面的垂直方 向由前框和胶框夹持固定， 所述前框为板状。
优选的， 所述前框包括四条独立的子前框， 四条子前框首尾连接形成矩形 的前框。 采用子前框拼接的方式， 可以筒化前框结构， 出模的时候可以单条子 前框分别取出， 降低了出模的难度。
优选的， 所述胶框为一体成型的结构。 一体成型的结构可以筒化后续前框 的安装步骤， 并且前框连接强度也比较高。
优选的， 所述前框的边缘位于所述胶框的顶部的内侧， 胶框的顶部和所述 前框的外表面平齐， 可以提高液晶显示装置表面的平整度。
优选的， 所述前框和胶框采用同一种材料。 采用同一种材料有利于共模生 产， 节省模具费用并且提高生产效率。
优选的， 所述液晶显示装置包括背板， 所述背板往前框方向设有折边面， 所述前框、 胶框和背板的折边面通过螺丝固定； 所述前框的外表面在螺丝固定 的位置处设有下沉面。 背板、 胶框、 前框的固定结构中有一个面是叠加在一起 的， 用 1 个螺丝就能同时实现背板、 胶框、 前框的固定， 安装效率高。 螺丝固 定后， 其头部会高出其固定面， 设置下沉面后， 螺丝头部表面就基本跟整个前 框的外表面平齐， 提高平整度。
优选的， 所述前框面对液晶面板的内表面设有内沉面。 内沉面可以避让液 晶面板边缘的电路， 避免导电膜跟电路接触造成短路。
本发明由于液晶面板平面方向的自由度由胶框固定、 垂直液晶面板的方向 由前框和胶框夹持固定， 所述前框为板状， 这样前框只在垂直于液晶面板的方 向（Z轴方向）对液晶面板进行定位， 其他方向的定位由胶框来实现， 这就大幅 筒化了前框的结构， 降低前框的开模成本， 更进一步的， 可以将前框和胶框采 用同一模具共模成型， 这样模具成本更低， 而且一次注塑可以同时产生前框和 胶框， 有利于生产效率的提高， 降低生产成本。

【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
一种液晶显示装置的制作方法， 包括前框 100和胶框 200的制作方法：
A: 在同一模具中设计出板状的前框 100和胶框 200的图形； B: 在所述模具中注塑， 脱模后形成所述前框 100和胶框 200。
如图 7所示， 前框图形包括四条独立的子前框图形， 以及四条子前框首尾 连接形成的矩形前框的拼接结构图形。 采用子前框拼接的方式， 可以筒化前框 结构， 出模的时候可以单条子前框分别取出， 降低了出模的难度。 胶框图形为 采用一体成型的图形结构， 一体成型的结构可以筒化后续前框的安装步骤， 并 且前框连接强度也比较高。 当然， 胶框也可以采用分段的方式， 采用多条子胶 框拼接的结构， 以筒化结构， 方便出模。
现有的液晶显示装置由于前框 100复杂， 前框 100和中框加起来需要 3套 模具才能加工出来， 而本发明采用了筒化的前框 100设计， 可以在一套模具中 同时出来中框和前框 100。
如图 7-11所示， 一种液晶显示装置， 包括采用上述方法制作的前框 100、 胶框 200和背板 300, 所述前框 100和胶框 200之间夹持有液晶面板 400, 液晶 面板 400平面方向的自由度由胶框 200固定、 垂直液晶面板 400的方向由前框 100和胶框 200夹持固定， 前框 100为板状， 前框 100的边缘位于所述胶框 200 的顶部的内侧， 胶框 200顶部的内侧 4氐住前框 100侧面， 其顶部和所述前框 100 的外表面平齐。 前框包括四条独立的子前框 140, 四条子前框 140首尾连接形成 矩形的前框。 采用子前框 140拼接的方式， 可以筒化前框结构， 出模的时候可 以单条子前框 140分别取出， 降低了出模的难度。 胶框为采用一体成型的结构， 一体成型的结构可以筒化后续前框的安装步骤， 并且前框连接强度也比较高。 当然， 胶框也可以采用分段的方式， 采用多条子胶框拼接的结构， 以筒化结构， 方便出模。
上述的前框 100无折边， 就一个板状面， 跟胶框 200的顶部固定， 可以进 一步筒化前框 100结构， 降低成本， 胶框 200顶部和前框 100的外表面平齐， 可以提高液晶显示装置表面的平整度。 当然， 前框 100设置折边， 包住胶框 200 的顶部， 并在胶框 200的侧面跟胶框 200固定在一起也是可以的。
液晶显示装置包括背板 300, 背板 300内部承托有导光板 500, 其侧壁上设 有卡勾 310,相应的，胶框 200的侧壁设有跟卡勾 310配合的开孔 220。卡勾 310 和开孔 220配合可以固定背板 300, 也方便背板 300的拆卸。 背板 300往前框 100方向设有折边面 320, 前框 100、 胶框 200和背板 300的折边面 320, 这样 背板 300、 胶框 200、 前框 100的固定结构中有一个面是叠加在一起， 可以用 1 个螺丝 600同时固定背板 300、 胶框 200、 前框 100, 安装效率高。 当然， 通过 粘贴、 焊接、 铆接等技术进行固定也是可以的。
由于螺丝 600固定后， 其头部会高出其固定面， 可以在前框 100的对应螺 丝 600固定的位置处的外表面设置下沉面 130。设置下沉面 130后， 螺丝 600头 部表面就基本跟整个前框 100的外表面平齐， 提高平整度。
前框 100在夹持液晶面板 400的一面还设置有导电膜 120,导电膜 120通过 螺栓跟背板 300电连接， 将液晶面板 400表面产生的静电导入到装置后面的金 属背板 300上， 提高液晶面板 400的可靠性。 前框 100面对液晶面板 400的内 表面设有内沉面 110, 内沉面 110可以避让液晶面板 400边缘的电路， 避免导电 膜 120跟电路接触造成短路。
为了节省模具数量， 降低模具成本， 前框 100和胶框 200可以采用同一种 材料。
本发明的前框 100仅固定液晶面板 400 ( panel ) Z轴方向的自由度， 此方 式既可以达到固定液晶面板 400 ( panel )的目的， 同时也很大程度的筒化了前框 100的设计；基于此种设计，可将前框 100同胶框 200采用同种塑胶材料注成型， 此种方式既可以实现固定液晶面板 400 ( panel )的目的， 同时也可以将前框 100 及胶框 200采用同一套模具注塑成型， 从而实现筒化产品设计， 降低模具及产 品材料成本的目的。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
