Description

一种显示装置 技术领域
[0001] 本申请涉及显示技术领域, 尤其涉及一种显示装置。
[0002]
[0003] 背景技术
[0004] 随着科技和经济的持续发展, 具备显示面板的智能手机、 平板电脑、 液晶电视 、 个人数字助理 (PDA)、 数字相机、 计算机屏幕或笔记本电脑屏幕等电子产品得 到了空前普及, 同吋对这些电子产品的显示面板的质量、 性能等方面也提出了 越来越高的要求。 因此, 制备具有高画质、 低功率、 无辐射、 显示稳定等优越 特性的品质及性能可靠的显示面板成为占领液晶显示市场必不可少的竞争力之
[0005] 由于制备液晶显示面板所需的材料 (如液晶、 PI液等)、 制作工艺 (如贴片摩擦的 方向或角度等)以及显示装置自身的结构等原因, 几乎所有尺寸的液晶背光模组 均会发生或轻或重的暗态漏光现象, 从而影响整个显示画面的质量。 比如, 在 液晶显示器的扇出区中, 所述扇出区的金属占空比不是百分之百, 导致会有大 量的光从该扇出区金属走线的空隙中穿过漏出, 并且由于该扇出区存在一定量 的液晶, 以及该扇出区阵列基板侧的地形复杂, 造成该扇出区内的液晶倒向混 舌 L, 因此, 当背光从该扇出区穿过吋, 光的偏振方向会发生不同程度地偏转。 当该扇出区没有黑色矩阵 (Black Matrix) , 则会发生漏光的现象; 即便该扇出 区有该黑色矩阵, 当该黑色矩阵的光密度值不够吋, 该扇出区也会发生不同程 度上的漏光现象; 我们称这种现象为扇出区漏光。 现有技术中, 可以通过材料 的变更及工艺的改进来减轻材料和工艺弓 I起的漏光现象, 但是由显示装置自身 结构引起的漏光现象仍会存在。 这吋, 若一味地去提升黑色矩阵的光密度值, 会大大增加生产成本。
[0006] 因此, 如何结合液晶显示器的 Open cell (指已贴好偏光片、 驱动电路、 柔性电 路板、 印刷电路板等电子元器件的液晶显示面板)的内部走线进行显示装置的设 计改进, 以彻底解决扇出区漏光的问题, 是本领域技术人员亟待解决的技术问 题。
