Description

液晶显示装置 技术领域
本发明涉及液晶显示领域， 尤其涉及一种液晶显示装置。 背景技术
液晶显示装置 （LCD, Liquid Crystal Display )具有机身薄、 省电、 无 辐射等众多优点， 得到了广泛的应用。 现有市场上的液晶显示装置大部分 为背光型液晶显示器， 其包括液晶面板及背光模组（backlight module ) 。 液晶面板的工作原理是在两片平行的玻璃当中放置液晶分子， 两片玻璃中 间有许多垂直和水平的细小电线， 通过通电与否来控制液晶分子改变方 向， 将背光模组的光线折射出来产生画面。 由于液晶面板本身不发光， 需 要借由背光模组提供的光源来正常显示影像， 因此， 背光模组成为液晶显 示装置的关键组件之一。 背光模组依照光源入射位置的不同分成侧入式背 光模组与直下式背光模组两种。 直下式背光模组是将发光光源例如 CCFL(Cold Cathode Fluorescent Lamp , 阴极萤光灯管）或 LED(Light Emitting Diode发光二极管)设置在液晶面板后方， 直接形成面光源提供给 液晶面板。 而侧入式背光模组是将发光光源 LED 灯条（lightbar )设于液 晶面板侧后方的背板边缘， LED灯条发出的光线从导光板一侧的入光面进 入导光板， 经反射和扩散后从导光板出光面出射， 以形成面光源提供给液 晶面板。
请参阅图 1 , 液晶显示装置一般包括： 背光模组 100、 设于背光模组 100上的胶框 300、 设于胶框 300上的液晶显示面板 500及设于液晶显示 面板 500上的前壳 700, 所述背光模组 100 包括背板 102、 设于背板 100 内的导光板 104、 设于背板 102 内的背光源 （未图示） ， 该背光模组 100 用于给液晶显示面板 500提供光照均匀的面光源， 所述胶框 300用于承载 液晶显示面板 500, 前壳 700将液晶显示面板 500固定于胶框 300内， 液 晶显示面板 500包括 TFT (薄膜晶体管）基板 502、 与 TFT基板 502相对 贴合设置的 CF (彩膜滤光片 )基板 504及设于 TFT基板 502与 CF基板 504之间的液晶 （未图示） ， 该 TFT基板 502与 CF基板 504贴合后， 在 TFT基板 502边缘位置形成有断差位置 524, 该断差位置 524用于贴附软 性线路板 ( COF ) 526以为液晶显示面板 500提供驱动电压。
所述前壳 700 —般由塑胶材料制成， 以控制生产成本， 所述背板 102 一般由金属材料制成， 如铁， 以保证背光模组 100 的强度。 该种结构的液 晶显示装置会导致软性线路板 526产生的静电无法释放， 可能出现静电击 穿软性线路板 526与 IC (半导体元件 ) (未图示） 的问题， 进而影响液晶 显示装置的品质。
针对上述问题， 中国专利 （申请号： 201210068995.6 )公开一种液晶 显示装置 （如图 2所示） ， 从外到内依次包括相互配合固定的前壳 100，、 胶框 300，和背板 500，， 所述前壳 100，和胶框 300，之间夹持有液晶面板 700' , 所述前壳 100，采用绝缘材料， 所述前壳 100，的表面设有导电膜 102' , 所述背板 500，采用导电材料， 所述导电膜 102，和背板 500，之间连接 有导电部件 502，， 所述导电膜 102，通过所述导电部件 502，跟所述背板 500， 电连接。 本发明通过导电部件 502，将导电膜 102，和导电材质的背板 500，相 连接， 柔性电路板（未图示）产生的静电可以通过导电膜 102，释放到背板 500，上， 有效避免电路板和 IC的被静电击穿。
上述方案虽然有效解决了静电释放的问题， 但却存在如下问题： 1、 连通前壳和背板的导电部件会造成塑胶前壳的成本优势下降；
2、 粘贴导电部件会造成人力成本的浪费；
3、 导电部件粘贴后， 可能会有脱落的风险， 造成品质上的风险。 发明内容
