 背景技术
现有显示屏1中，如图1所示，在盖板11和显示面板13设置了黑色遮挡层12，用于遮挡其内部线路。进一步的，在盖板11和显示面板13之间还设置了胶体层14，用于对盖板11和显示面板13进行贴合，防止外界水氧对显示屏1内部器件的侵蚀。

本发明实施例提供了一种显示装置。该显示装置包括一显示屏。请参照图2，图1为本发明实施例提供的显示屏的结构示意图。如图2所示，该显示屏2包括显示面板21，贴合层22，遮挡层23以及盖板24。其中，贴合层22设置在显示面板21上，遮挡层23设置在贴合层22上，盖板24设置在遮挡层23上。
显示面板21可以为液晶显示面板，也可以为有机发光面板，在此不作具体限定。盖板24覆盖在显示面板21上。盖板24可以采用玻璃、蓝宝石或陶瓷等高硬度材料制成，其耐磨性能较好，可以保护显示面板21内的部件。
为了避免显示面板21内的部件在外观面上暴露，在盖板24靠近显示面板21的一侧设置了遮挡层23。其中，遮挡层23可以采用遮光材料制成，具体的，比如透光率小于10%的材料。具体的，遮挡层23的组成材料可以包括黑色油墨。
贴合层22设置在遮挡层23和显示面板21之间。其中，贴合层22的组成材料包括UV胶，UV胶在紫外光的照射下固化，可以将显示面板21和盖板24固定在一起。
其中，遮挡层23或贴合层22内具有光敏材料，光敏材料在紫外光照下透光率变小。其中，光敏材料包括卤化银，比如溴化银、碘化银等。举例来说，碘化银为微黄色固体。当使用紫外线对贴合层22进行固化时，紫外线可以透过遮挡层23中碘化银照射到UV胶上，或者照射到贴合层22内的UV胶上，使UV胶固化。随着UV胶固化的结束，碘化银也在紫外光的照射下分解变成黑色，使遮挡层23或贴合层22的透光率变小，实现对显示面板21内部器件的遮挡。综上，遮挡层23或贴合层22内具有光敏材料不仅可以保证UV胶在足够多的紫外光照射下固化，又可以提高显示屏1的遮挡性能。
在一实施例中，当遮挡层23内具有光敏材料时，光敏材料在遮挡层23中的质量比例为10%至50%之间。
当遮挡层23内具有光敏材料时，如图2所示，遮挡层23包括：光敏区231和遮挡区232。其中，光敏区231的组成材料包括光敏材料。遮挡区232设置在光敏区231的两侧，遮挡区232的组成材料包括遮光材料。其中，光敏区231与贴合层22相对设置。
如图3所示，当UV灯3从靠近盖板24的一侧向贴合层22发射紫外光时，可以透过光敏区231的光敏材料照射到贴合层22上，使贴合层22的UV胶固化。随着贴合层22固化过程结束，光敏区231中的光敏材料在紫外光的照射下透光率变小，与遮挡区232一起实现遮挡显示面板21内器件的功能。
当贴合层22具有光敏材料时，遮挡层23包括：第一遮挡部233，第二遮挡部234，以及设置在第二遮挡部234和第一遮挡部233之间的开口区235。
在一实施例中，贴合层22包括：掺杂区221，掺杂区221的的组成材料包括胶体和光敏材料。其中，光敏材料在掺杂区221中的掺杂比例为10%至50%之间。
需要说明的是，在一实施例中，可以在整个贴合层内掺杂光敏材料，即贴合层22仅包含掺杂区221。在另一实施例中，如图4所示，贴合层22还可以包括非掺杂区222。其中，非掺杂区222的组成材料为胶体，不包含光敏材料，可以提高贴合层22的粘贴性能。
其中，贴合层22的掺杂区221与开口区235相对设置，贴合层22的非掺杂区222与第二遮挡部234相对设置，且与第一遮挡部233相对设置。如图5所示，当UV灯3从靠近盖板24的一侧向贴合层22发射紫外光时，贴合层22的UV胶开始固化。随着贴合层22固化过程结束，掺杂区221中的光敏材料在紫外线的照射下透光率变小，与第二遮挡部234和第一遮挡部233一起实现遮挡显示面板21内器件的功能。
当贴合层22具有光敏材料时，贴合层22包括层叠设置的胶体层223和光敏层224。光敏层224与开口区235相对设置。在一实施例中，如图6所示，光敏层223设置在显示面板21上，胶体层224设置在光敏层223和遮挡层23之间。在另一实施例中，如图7所示，胶体层224设置在显示面板21上，光敏层223设置在胶体层224和遮挡层23之间。其中，光敏层223的厚度范围在0.02毫米至0.2毫米之间。
如图8或9所示，当UV灯3从靠近盖板24的一侧向贴合层22发射紫外光时，胶体层224的UV胶开始固化。随着贴胶体层224固化过程结束，光敏层223中的光敏材料在紫外光的照射下透光率变小，与第二遮挡部234和第一遮挡部233一起实现遮挡显示面板21内器件的功能。
本发明实施例的显示屏和显示装置通过在遮挡层或贴合层内设置光敏材料，使光敏材料在紫外光照下透光率变小，可以提高显示屏的遮挡性。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种显示屏和显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
