所述液晶显示装置一般包括: 后壳、 与后壳配合设置的前壳、 设于后 壳内的背光模组、 设于背光模组上的胶框及设于胶框上的液晶显示面板, 其中, 胶框用于承载液晶显示面板, 前壳用于固定液晶显示面板。
所述液晶显示面板包括彩膜基板 ( Color Filter, CF ) 、 薄膜晶体管基 板(Thin Film Transistor, TFT), 夹于彩膜基板与薄膜晶体管基板之间的液 晶 ( Liquid Crystal, LC )及密封胶框( Sealant , 该 CF基板与 TFT基板 的边缘处形成有一断差, 用于电性连接外部设备, 进而驱动液晶显示面 板。
随着液晶显示装置生产技术不断的发展, 液晶显示装置逐步趋向窄边 框化, 进一步向无边框方向发展, 而无边框液晶显示装置的液晶显示面板 和背光模组的固定方式, 成为当今的一大课题。
请参阅图 1 , 为现有的无边框液晶显示装置的结构示意图, 其包括: 后壳 100、 设于后壳 100内的胶框 200, 设于胶框 200内的背光模组 300, 设于胶框 200内并设于背光模组 300上的液晶显示面板 400, 该液晶显示 面板 400通过粘接构件 ( 如, 胶氷, 瞬时粘合剂、 热固性粘合剂或可光 固化的粘合剂 500粘接至胶框 200上, 背光模组 300也通过粘接的方式 固定于胶框 200上, 进而实现无边框液晶显示装置的液晶显示面板 400和 背光模组 300的固定; 同时, 在胶框 200的一侧和与胶框 200这一侧平行 的后壳 100侧壁 120的一个侧壁之间制备有电路容置部 600, 用于放置与 液晶显示面板 400电性连接的多个电路膜 700及 PCB板 800, 并通过一装 饰盖 900盖住该电路容置部 600, 进而实现无边框液晶显示装置的 PCB板 800 的固定。 该现有技术由于不使用液晶显示装置通常所需的前壳, 因而 可以以新颖的结构使厚度最小化并提高美感, 同时将原本置于背光模组 300下方的 PCB板 800置于液晶显示面板 400的侧边, 进一步降低了液晶 显示装置的厚度。
