Description

显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种显示装置。
 背景技术
在现代社会，手机等移动终端给人们的生活带来了越来越多的便利，并逐渐成为生活中不可或缺的一部分。随着生活质量的提高，人们对手机的使用体验也提出了更高的要求。开发商为了迎合社会需求，开发出了全面屏设计。手机等移动终端的全面屏制造技术的高低，直接影响了开发商的市场份额。
全面屏是指屏占比接近100%的显示屏。前置摄像头区域的显示屏设计是影响屏占比的关键因素。为了实现全面屏，一般会在摄像头区域设计为盲孔结构，即保留摄像头区域显示屏大部分结构，仅对上偏光片进行挖孔，现有技术中主要存在以下两种设计：
一种是如图1所示的结构，将位于显示面板14和玻璃盖板11之间的上偏光片13和光学透明胶12进行挖孔，并且使挖孔区域与摄像头15的位置相对应，然后使用光学透明树脂16填充挖孔区域，由于光学透明树脂16在填充过程中的状态是液态，因此很容易产生气泡或溢胶等不良现象；而且光学透明树脂16与光学透明胶12的热膨胀系数不一致也会在二者界面处产生孔隙。
另一种是如图2所示的结构，采用厚度较薄的上偏光片23，并在所述上偏光片23与摄像头25相对的区域进行挖孔，形成挖孔区域23a，然后直接用整块光学透明胶22粘接在所述上偏光片23的上侧，由于所述上偏光片23厚度较小，所述光学透明胶22依靠自身变形填充所述挖孔区域23a，但在所述挖孔区域23a内，很容易因空气未完全排出而形成气泡，产品良率无法保证。
 技术问题
现有技术中，为了提高显示屏的屏占比，并保证位于摄像头上方的显示屏具有良好的透光性，会采用将摄像头上方的上偏光片先挖孔，然后填充透明材料的方法。但在填充透明材料的过程中会出现产生气泡和溢胶等不良现象，严重影响产品质量和制程良率。

所述显示面板54与所述摄像头55相对的区域为第二区域54a，所述第二区域54a的透光率大于所述显示面板54上除所述第二区域54a之外的区域的透光率，其透光率大于90%。可选的，为了实现所述第二区域54a的高透光率，所述第二区域54a内不包括色阻层、金属层及液晶543；所述色阻层可以是所述显示面板54中的红、绿、蓝三色色阻；所述金属层可以是所述显示面板54中的金属走线或金属电极。在进行所述显示面板54的制造时，可以使用具有特定形状的掩膜板，使所述第二区域54a仅保留基板，不设置会对光线起阻挡或削弱作用的色阻层、金属层、液晶等，从而保证所述第二区域54a的高透光性。
所述下偏光片57及所述背光模组58与所述摄像头55相对的区域为第三区域57a，所述第三区域57a为通孔区域，以保证射向所述摄像头的光线穿过所述第三区域57a时，不产生光能损耗。
需要说明的是，本申请中所述的“元件与摄像头相对的区域”，如：所述上偏光片与所述摄像头相对的区域、所述显示面板与所述摄像头相对的区域、所述下偏光片及所述背光模组与所述摄像头相对的区域，等，均指所述摄像头在所述元件上的垂直投影区。
本申请实施例提供的显示装置，直接将上偏光片与摄像头相对的区域设置为高透光区，从而无需对所述上偏光片进行挖孔后再填充的操作，避免了此操作引发的气泡、溢胶等不良，既简化了制程，又保证了摄像头的光线摄取量。
综上所述，虽然本申请以具体实施例揭露如上，但上述实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
