Description

一种液晶显示器及其窄边框结构 技术领域
本发明涉及液晶显示技术领域, 尤其是液晶显示器的窄边框结构。 背景技术
如今, 窄边框结构的液晶显示器已经成为一种趋势。现有的液晶显示器通 常包括前框, 前框主要用于压住液晶模块, 防止液晶模块的脱离。 而窄前框设 计的整机,一般也常采用包边式的外观方案,即使用侧边壳包住液晶显示模组。 随着显示技术的发展, 无前框的液晶显示器更显示出时尚的外观。 图 1为采用 无前框液晶显示模组的整机设计示意图, 由于没有前框, 液晶模块 1的边缘直 接暴露在外面,而玻璃脆弱,容易造成液晶模块边缘破裂, 以致画面显示异常。 目前的解决办法为在液晶模块 1的边缘涂布密封胶 2, 材质可以为硅胶、 环氧 树脂等。 由于密封胶具有弹性, 可以起到缓冲作用, 降低了边缘破裂风险。 此 方式有一缺点, 涂布密封胶作业较为麻烦, 而且液晶模块的玻璃边缘切割断面 不平整, 容易造成密封胶粘附不牢, 存在脱落风险。
由于无前框液晶显示模组的玻璃已靠近最外边缘, 常规做法为包边式外壳设 计, 外观设计较为单一, 见图中的侧边壳 3。 现有的无前框液晶显示模组无法 提供多种的整机外观需求。 另外, 整机外壳采用包边结构, 外壳锁附到模组的 背框上, 容易造成外壳外翻, 形成间隙不均等现象。 侧边壳需与模组留有间隙 D1 , 不利于縮小边框。 发明内容

优选地, 还包括侧外框, 所述侧外框由一体垂直连接的侧向框和底向框构 成, 其中侧向框与所述台阶对接, 底向框与背框固定连接。 可以很好地支持前 侧壁不至外翘变形。

附图说明
图 1是现有液晶显示器的窄边框结构示意图。
图 2是实施例 1液晶显示器窄边框结构示意图。
图 3是实施例 2液晶显示器窄边框结构示意图。
图 4是实施例 3液晶显示器窄边框结构示意图。
图 5是实施例 4液晶显示器窄边框结构示意图。
图 6是实施例 5液晶显示器窄边框结构示意图。 具体实施方式
下面结合附图用实施例对本发明作详细说明。 实施例 1
如图 2所示, 本实施例中液晶显示器包括液晶显示模块 10、 背框 20, 其 中液晶显示模块 10由液晶模块 11和背光模块 12组成, 还包括中框 30, 其中 中框 30由侧壁 31和固定连接于侧壁 31的水平壁 32构成, 呈 T形, 水平壁 32将侧壁 31分为前侧壁 311和后侧壁 312, 如图所见, 液晶模块 11固定于水 平壁 32上且其侧边对应前侧壁 311的内侧, 也可以如图 1所示在液晶模块 11 的边缘 A处涂布密封胶 (图中未示出), 其中, 液晶模块 11与中框 30的水平 壁 32连接方式是, 在液晶模块 11的下玻璃基板 13粘贴发泡型双面胶 14, 并 粘合到中框的水平壁 32, 玻璃和中框由于材质不同, 其材料膨胀率不同, 如果 直接粘接往往会造成中框与玻璃粘合处脱离, 而发泡型双面胶厚度略厚, 且较 软, 可吸收因材料膨胀率差异造成的变形; 另外, 也可以是在液晶模块的下玻 璃表面粘贴塑胶件, 塑胶件与背框固定连接, 从而把液晶模块与中框连接在一 起。 后侧壁 312与背框 20固定连接, 连接方式可以是螺丝方式也可以是胶粘, 背光模块 12固定于背框 20上。
考虑到窄边的视觉效果, 同时还需要兼顾中框的强度要求, 一般中框 30 可以采用塑胶材质, 也可以采用挤出或铸造成型的金属材质等, 其中侧壁 31 的厚度在 0.4至 2mm之间为宜, 本实施采用塑胶材料, 其厚度为 2mm。 中框 30前侧壁 311端部在设计上应该略高于液晶模块 11表面, 当有垂直 于玻璃的外力作用时, 例如液晶显示器侧倾或朝下放置时, 中框 30的前侧壁 将先受力, 把力传递到背框 20上, 从而降低玻璃破裂风险。
本实施例结构相对现有减少了前框和***的侧边壳, 减少了材料的使用, 减低了成本, 突出了窄边的视觉效果, 而且并不降低对液晶显示模块的保护。
实施例 2
本实施例结构如图 3所示, 区别于实施例 1, 中框 30的侧壁 31由一体成 型的前侧壁 311和縮进的后侧壁 312两部分构成, 即后侧壁 312与前侧壁 311 形成台阶, 同时还包括侧外框 40, 所述侧外框 40由一体垂直连接的侧向框 41 和底向框 42构成, 其中侧向框 41与所述台阶对接, 底向框 42与背框 20固定 连接, 固定连接方式可以是螺丝连接, 也可以是铆接。 为了达到外观整体统一 的视觉效果, 本实施例的侧外框 40外表面与前侧壁 311外表面同一平面。 这 种结构设计, 可以防止前侧壁 311外翘, 因为当前侧壁 311外翘时势必在台阶 处发生弯折并对侧外框 40端部 B产生压力, 而在侧外框 40与背框 20固定连 接时, 可以施于反作用力使得前侧壁 311 恢复原来的状态。 本实施例中框 30 采用铸造成型的金属材质, 其中侧壁 31的厚度为 0.4mm。
实施例 3
参见图 4,本实施例区别于实施例 2在于, 中框 30的台阶还包括沿着后侧 壁 312表面向前侧壁 311方向縮进的凹槽 33, 相对应地, 侧外框 40的端部设 有凸边 43。这种结构可以加强侧外框 40和中框 30的结合,不会发生错位等情 况, 而且对前侧壁 311的作用效果和实施例 2相同, 这里不再赘述。 实施例 4
见图 5, 区别于实施例 3在于, 本实施例的侧外框 40结构做了改进, 先看 中框 30, 和实施例 2、 实施例 3相同, 中框 30的台阶还是包括沿着后侧壁 312 表面向前侧壁 311方向縮进的凹槽 33,并形成一向前侧壁 311延伸方向相反的 卡隼 34, 本实施例中, 侧外框 40 的厚度明显大于台阶的高度, 而侧外框 40 的端部与卡隼 34对应设有卡槽 43, 即安装时卡隼 34插于卡槽 43中, 进一歩 加强了中框 30和侧外框 40的连接。 同时可以对侧外框 40进行一些表面处理, 如氧化、 拉丝等, 形成与中框的视觉美感差异。 本实施例侧外框 40采用铝金 属材质, 以利于进行氧化、 拉丝等表面处理, 中框 30仍采用塑胶注塑成型。
实施例 5
本实施例是窄边框液晶显示器结构的例外, 如图 6所示, 这种结构依然包 括中框 30和侧外框 40结构, 所不同的是, 中框 30和侧外框 40并不是紧密方 式连接在一起的, 即侧外框 40完全包住中框 30, 这种结构并非严格意义上的 窄边框, 但是, 可以沿用传统的窄边框整机模具, 有利于整机外观的多样化设 计, 满足不同的设计需求。 而且相对于有前框的液晶显示屏而言还是进一歩縮 小了边框。 以上优选几个实施例对本发明进行说明, 并不能理解为本发明仅限于以上 方式, 本领域的普通技术人员应该理解, 在不脱离由权利要求限定的本发明的 精神和范围的情况下, 可以对其进行形式和细节的各种改变。
