Description

一种一体化液晶显示装置
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种一体化液晶显示装置。 【背景技术】
随着人们对超薄化（Ultra-slim )液晶显示装置的时尚性追求， 市场已涌现 出很多薄型化的设计。 以 LED液晶电视为例， 在目前看来做的比较成功的就是 一体机（All-in-one ) LED液晶电视， 其将传统的液晶模组与 TV系统整合在一 起， 不同的厂家整合的程度有所不同。 液晶模组一般都包括有背光模组、 及设 置在背光模组上方的液晶面板， 背光模组一般包括有： LED, 用于将 LED的光 分散导光的导光板、 导光板的下方往往还设置有反射片， 用于将射入反射片的 光线反射回导光板， 一体式的液晶电视的背光模组和液晶面板共用的一前框以 减小体积， 但由于背光模组的 LED往往有部分光线直接射到前框上， 前框会吸 收液晶模组内背光模组的 LED的光线， 从而得 LED光线的利用率不够高。
【发明内容】
本发明所要解决的技术问题是提供一种液晶模组的 LED光线利用率较高的 一体化液晶显示装置。
本发明的目的是通过以下技术方案来实现的： 一种一体化液晶显示装置， 包括： 背光模组、 置于背光模组上方的液晶面板以及设在边沿处由背光模组和 液晶面板共用的前框； 其中， 所述前框上对应于背光模组的 LED的位置处设置 有反射层。
所述反射层设置于前框在 LED上方的位置处。由于 LED的上方为其光线主 要漏出处， 因此， 于前框在 LED上方的位置处设置反射层， 效果尤佳。
所述反射层为银反射层。 银为常用的具有较好反射效果的反光材料。
优选的， 所述前框为金属结构。 金属结构的前框结构刚度较好， 同时可以 辅助散热， 且较容易加工呈较为复杂的形状。
优选的， 所述背光模组内设有用于对 LED散热的散热板， 所述前框与所述 散热板热导通。 将前框与散热板热导通， 增加了散热路径， 散热板可通过金属 前框更好的散热。
所述前框为一体成型的阶梯状结构， 其包括： 对应于设置在背光模组边缘 的第一前框和对应于液晶面板边缘的第二前框， 所述第二前框包括： 设置于背 光模组的 LED上方的面框和设置于背光模组侧方的侧框； 所述反射层设置于所 述面框的内侧面。 由于背光模组的边缘设有 LED, 背光模组此处的宽度往往是 大于液晶面板的， 在液晶面板边缘设置缩进的第二前框， 阶梯结构的前框适应 于液晶面板及背光模组的组装， 可以更好的防止 LED的光线不通过导光板直接 射入液晶面板中， 而背光模组边缘的第一前框的面框的内侧面接受到的 LED的 光较多， 在此处设置反射片效果更佳。
所述背光模组内设有用于对 LED散热的散热板， 所述前框为金属前框， 所 述的金属前框的面框的内侧面与背光模组内的散热板接触。 阶梯状的前框的在 背光模组边缘的第一前框刚好位于散热板边侧， 不用做大的结构上的改动即可 将金属前框的面框的内侧面与散热板接触， 使得散热板可通过金属前框更好的 散热。
优选的， 所述反射层为银反射层， 所述的金属前框的面框的内侧面通过银 反射层与背光模组内的散热板接触。 银反射层不仅有较好的反射效果， 而且银 的导热率较高， 从而可以更好的将散热板上的热量传导到前框中， 提高散热效 率。
优选的， 所述背光模组内设有导光板及反射片， 所述金属前框的面框与导 光板或反射片平行设置。 这样的设计使得面框的反射层配合导光板和反射片， 其反射 LED光线的效率更高。
所述的一体化液晶显示装置为一体化液晶电视。
本发明由于在背光模组及液晶面板共用的前框对应于 LED的位置设置了反 射层， 通过反射层反射 LED所发出的照射到前框的光线， 从而減小前框对 LED 所发出光线的吸收， 有利于将照射到前框的光线反射 ^导光板或是反射片上， 提高了 LED光线的利用率。
【附图说明】

图 1是本发明实施例的局部视图。
其中： 1、 前框； 11、 第一前框； 12、 第二前框； 15、 面框； 16、 側框； 21、 散热板； 22、 LED; 23、 背板； 24、 导光板； 25、 反射片； 26、 光学膜片； 27、 液晶面板； 7、 银反射层。
【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。
本发明实施例一体化液晶显示装置采用一体化装配结构， 其包括背光模组、 置于:背光模组上方的液晶面板， 将液晶面板与背光模组一起整合， 背光模组和 液晶面板共用前框，其中， 前框上对应于背光模组的 LED 的位置处设置有反射 层。 ：
下面仍以一体化液晶电视为例， 对一体化液晶显示装置的结构进行具体说 明。 如图 1及图 2所示， 一体化液晶电视包括有背光模组、 置于背光裤组上方 的光学膜片 26及液晶面板 27、 背光模组包括有设置在背光腔内的 LED22、 背 板 23、 用于将 LED22的光分散导光的导光板 24、 导光板 24的下方还设置有反 射片 25, 用于将射入反射片 25的光线反射回导光板 24。 LED22下方还设有散 热板 21 , 用于对 LED22散热。
如图 2所示， 前框 1为一体成型的阶梯状结构， 其包括： 对应于设置在背光 模組边缘的第一前框 11和对应于液晶面板 27边缘的第二前框 12, 该第一前框 11与第二前框 12皆呈 L形或类似形状， 所述第二前框 12包括： 设置于背光模
更正页 （细则第 91条) 组的 LED22上方的面框 15和设置于背光模组侧方的侧框 16; 该面框 15位于 LED 22的上方， 为了避免第一前框 11对 LED 22所发出光线的吸收， 在该第一 前框 II的面框 15内側面设置有一层用于反射光线的银反射层 7，从而将 LED 22 所发出的光线反射到导光板 24及反射片 25中， 以提高 LED 22光线的利用率。 当然 > 也寸以在前框 1的其他对应于 LED22的位置处设置反射层， 只要此位置 会受到 LED光线照射都可以提高 LED光线的利用率。
另外， 可以将第一前框 11的面框 :15设置成与导光板 24或反射片 25相对平 行， 这样的设计使得面框 15的银反射层 7配合导 反 24和反射片 25, 其反射 LED22光线的效率更高。
阶梯状前框 1的设计主要是考虑 于背光模组的边缘设有 LED22,背光模组 此处的宽度往往是大于液晶面板 27的， 在液晶面板 27边缘设置縮进的第二前 框 12, 阶梯结构的前框 1适应于液晶面板 27及背光模组的组装， 可以更好的防 止 LED22的光线不通过导^ 24直 入液晶面板 27中， 而背光模组边缘的 笫一前框 II的面框 15的内侧面接受到的 LED22的光较多， 在此处设置反射片 25效杲更佳。 当然， 其他形状的前框也是可以的。
由于面框 1大部分面积暴露于空气中 , 若将其作为背光模组的散热組件将可 有效降低背光模组的温度。 而金属 —种导热性能较好的材料， 且较容易加工 成上述较为复杂的阶梯形状， 因而本实施例中面框 1 选用金属前框， 同时使所 述的金属前框 1的面框〗5的内侧面与背光模组内的散热板 21直接接触。如图 1 及图 2所示， 阶梯状的前框 1的在背光模组边缘的第一前框〗 1刚好位于散热板 21上端部的上方边側，不用做大的结构上的改动即可将金属前框 1的面框 15的 内侧面与散热板 21接触， 从而使散热板 21可直接将热量传导至前框 1上， 前 框 1再将热量散发到空气中， 使得散热板 2〗可通过金属前框 1更好的散热, 提 高了散热效率，降低了液晶电视内部妁温度。由于银的导热率较高 ,为 429w/iTLk, 而一般钢材导热率为 60w/m.k, 银的导热率比一般钢材的导热率都高， 因此， 本 实施例选用银反射层 7作为反射层， 可以很好的同时达到较好的反射效杲及较 更正页 （细则第 91条) 好的导热效杲。 当然， 所述的银反射层也可以采用其他的反射层代替， 如铝、 高分子聚合物等一些反射效率较高的 料等， 只要能达到较好的反射效果即可 实现本发明的目的。
所述的反射层可以电镀在所述前框上。 也可以涂布在所述前框上。
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 明， 如， 上述的一体化液晶显示装置并 不仅限于一体式（Ali-in-one )液晶 ^视， 也可用于其它的一体式液晶显示装置 中， 比如一体式（All-in-one ) LED i视器等 对于本发明所属技术领域 ^普通 技术人员来说， 在不脱离本发明构 ^的前提下， 还可以做出若千简单推^或替 换， 都应当视为属于本发明的保护范 :围。
