Description

显示装置 技术领域
本申请涉及显示领域，特别涉及一种显示装置。
 背景技术
随着液晶显示技术的发展，特别是全面屏技术的发展，目前多数厂商乃是将显示装置的背光模组设置面朝内的开孔，以供屏下摄像头对应放置，并藉此接收来自外界环境的入射光。
现有技术的显示装置中，当屏下摄像头对应地设置于所述显示装置所具有的背光模组的开孔下方时，所述开孔将仅仅作为所述屏下摄像头用以接收环境光的收发通道。为了保证背光模组中的背光源对开孔的干涉，常常在下偏光片与显示面板的间隙处、以及开孔区与背光源的交界处涂覆遮光胶。而由于遮光胶的涂覆精度以及与背光板开孔边缘胶层的干涉，使得遮光胶涂覆缺胶或溢胶，导致开孔形状变形或者开孔边缘线缺角，影响产品质量。
因此，亟需一种显示装置以解决上述技术问题。
