 本发明的实施方式
下面将结合本申请的实施例中的附图，对本申请的实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
本申请的实施例提供一种复合盖板及显示装置，以下分别进行详细说明。需要说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
如图1至图3所示，复合盖板100包括摄像区S1、至少部分包围摄像区S1的遮光区S2、以及至少部分包围遮光区S2的透光区S3。复合盖板100用于贴合至显示模组200，复合盖板100的摄像区S1则对应显示模组200上的摄像孔260所在区域。显示模组200上的摄像孔260内安装有摄像头270等光学元件，用于进行拍照或摄像等操作。复合盖板100的遮光区S2围设在摄像区S1周围，用于对显示模组200上摄像孔260的边缘结构进行遮挡，以避免影响成像和显示品质。复合盖板100的透光区S3则对应显示模组200的显示区，用于透射出显示模组200的显示画面。
复合盖板100包括保护层110，保护层110具有相对设置的第一表面111和第二表面112，第一表面111位于第二表面112背离显示模组200的一侧。保护层110作为复合盖板100的保护结构，其为整面设置。当复合盖板100贴合至显示模组200上后，保护层110也能够对显示模组200起到一定的保护作用，避免显示模组200受到外部环境或者作用力的损伤。其中，保护层110的材质能够为聚对苯二甲酸乙二酯（PET）或者透明聚酰亚胺（CPI）等透光材料。
复合盖板100包括遮光层120，遮光层120设置在保护层110的第二表面112，且遮光层120位于遮光区S2。遮光层120对应摄像区S1的位置形成有第一通孔121，即第一通孔121与显示模组200上的摄像孔260对应，以便于入射光线穿过保护层110后通过第一通孔121顺利进入显示模组200的摄像孔260内，以进行成像。遮光层120所用材料能够为油墨，用于对下方膜层结构，也就是显示模组200上摄像孔260的边缘结构进行遮挡，以避免影响最终的成像和显示品质。
复合盖板100包括粘接层130和盖板本体140，粘接层130设置在遮光层120背离保护层110的一侧。粘接层130能够为光学胶层，具有粘接功能的同时还具有透光性。盖板本体140则能够为超薄玻璃（UTG）等透光材质，以便于显示模组200的显示画面能够正常透过。盖板本体140设置在粘接层130背离保护层110的一侧，即盖板本体140通过粘接层130与保护层110连接。盖板本体140背离粘接层130的一侧则用于与显示模组200贴合，即复合盖板100制作完成后整体以盖板本体140背离粘接层130的一侧与显示模组200贴合，贴合时能够先在盖板本体140或显示模组200表面设置一层光学胶层，然后进行粘接贴合。
其中，保护层110对应遮光层120围合的区域沿第二表面112朝向第一表面111的方向凸出，并形成凸出部113，这是由于遮光层120仅设置在保护层110的第二表面112上对应遮光区S2的位置。当将盖板本体140通过粘接层130与保护层110贴合连接时，遮光层120会在盖板本体140的作用下挤压保护层110，从而使得保护层110对应遮光层120围合的区域，也就是保护层110上对应遮光区S2和摄像区S1的位置会朝远离盖板本体140的方向凸出并形成凸出部113。本申请中将凸出部113对应摄像区S1的部分在第一表面111朝向第二表面112的方向上的厚度设置为处处相等，即凸出部113上对应摄像区S1的部分的厚度均匀，从而使得进入摄像区S1的入射光线在穿过保护层110时不会产生光程差或者发生发散，进而能够避免入射光线发生光路畸变，改善复合盖板100贴合至显示模组200上后摄像区S1的成像品质。
本申请的实施例中复合盖板100包括依次设置的保护层110、遮光层120、粘接层130和盖板本体140。保护层110具有相对设置的第一表面111和第二表面112，遮光层120设置在第二表面112。遮光层120位于遮光区S2，遮光层120对应摄像区S1的位置形成有第一通孔121。盖板本体140背离粘接层130的一侧用于与显示模组200贴合。其中，保护层110对应遮光层120围合的区域沿第二表面112朝向第一表面111的方向凸出并形成凸出部113，凸出部113对应摄像区S1的部分在第一表面111朝向第二表面112的方向上的厚度处处相等。本申请通过将凸出部113上对应摄像区S1的部分设置为厚度均匀，能够避免进入摄像区S1的入射光线在穿过保护层110时产生光程差或者发生发散，从而避免入射光线发生光路畸变，改善复合盖板100贴合至显示模组200上后摄像区S1的成像品质。
可选的，如图1和图2所示，粘接层130上对应第一通孔121的位置开设有第二通孔131，第二通孔131的侧壁在保护层110上的正投影位于遮光层120在保护层110上的正投影内。即粘接层130在覆盖至遮光层120上时，粘接层130并未伸入遮光层120上的第一通孔121内，而是仅覆盖或部分覆盖遮光层120背离保护层110的一侧，以避免对摄像区S1对应的膜层结构的厚度均匀性产生影响，从而避免进入摄像区S1的入射光线因厚度差而产生光程差或者发生发散，进而避免入射光线发生光路畸变。
在一些实施例中，遮光层120呈环形，第二通孔131的侧壁与遮光层120的内壁之间具有第一间距，第二通孔131的侧壁与遮光层120的外壁之间具有第二间距。即粘接层130仅部分覆盖遮光层120背离保护层110的一侧，也就是第二通孔131的侧壁相对于第一通孔121的侧壁而言进行了内缩设计。此种设计方式使得遮光层120能够对粘接层130的第二通孔131的边缘进行有效遮挡，即使在一定倾斜角度的观察视角下也不会直接看到粘接层130上第二通孔131的边缘结构，从而改善成像和显示品质。
其中，第一间距大于或等于50微米，第二间距大于或等于50微米。若第一间距和/或第二间距过小，则会导致遮光层120无法有效遮挡第二通孔131的边缘结构，影响成像和显示品质。在实际制作过程中，能够将第一间距和第二间距分别设置为50微米、100微米、200微米、300微米、400微米或者500微米等，其具体值能够根据实际设计需求进行选择调整，此处并不做特殊限制。
对应的，能够将遮光层120的宽度（遮光层120的内径与外径的差值，也即遮光层120的内壁与外壁之间的间距）设置为大于或等于100微米且小于或等于1000微米。若遮光层120的宽度过大，则会影响复合盖板100贴合至显示模组200上后显示画面的面积占比；若遮光层120的宽度过小，则会导致遮光层120无法有效遮挡第二通孔131的边缘结构，影响成像和显示品质。在实际制作过程中，能够将遮光层120的宽度设置为100微米、200微米、400微米、600微米、800微米或者1000微米等，其具体值能够根据实际设计需求进行选择调整，此处并不做特殊限制。
需要说明的是，在将粘接层130设置在遮光层120背离保护层110的一侧时，能够先制作形成粘接层130，并在粘接层130上开设第二通孔131，然后再将粘接层130与印有遮光层120的保护层110贴合形成；或者，也能够在印有遮光层120的保护层110上设置圆形遮挡区域，然后在遮挡区域外进行涂布制作形成带有第二通孔131的粘接层130。其具体制作方式能够根据实际的制程需求进行选择调整，此处并不做特殊限制。
在另一些实施例中，如图2所示，盖板本体140上对应第二通孔131的位置开设有第三通孔141，即第三通孔141、第二通孔131和第一通孔121相互连通，以避免盖板本体140与粘接层130贴合后在盖板本体140与保护层110之间形成空气夹层，从而避免对摄像区S1的成像产生不良影响。其中，第三通孔141的侧壁在保护层110上的正投影位于遮光层120在保护层110上的正投影内，即第三通孔141的侧壁相对于第一通孔121的侧壁而言进行了内缩设计，此种设计方式使得遮光层120能够对盖板本体140的第三通孔141的边缘进行有效遮挡，从而改善成像和显示品质。
在又一些实施例中，第三通孔141的侧壁在保护层110上的正投影位于粘接层130在保护层110上的正投影内，即第三通孔141的侧壁相对于第二通孔131的侧壁而言进行了内缩设计。此种设计方式使得即使在一定倾斜角度的观察视角下也不会直接看到盖板本体140上第三通孔141的边缘结构，从而改善成像和显示品质。
其中，第三通孔141的侧壁与第二通孔131的侧壁之间具有第三间距，第三间距大于或等于50微米且小于或等于250微米。若第三间距过小，则可能会导致在某个倾斜角度的观察视角下，遮光层120的内壁无法对盖板本体140上第三通孔141的边缘结构进行有效遮挡，从而影响成像和显示品质。若第三间距过大，而保护层110与盖板本体140之间仅设置有具有透光性的粘接层130，则同样会导致在某个倾斜角度的观察视角下，遮光层120的外壁无法对盖板本体140上第三通孔141的边缘结构进行有效遮挡，从而影响成像和显示品质。
在实际制作过程中，能够将第三间距设置为50微米、100微米、150微米、200微米或者250微米等，其具体值能够根据实际设计需求进行选择调整，此处并不做特殊限制。
需要说明的是，在将盖板本体140贴合至粘接层130背离保护层110的一侧时，需要先对盖板本体140进行开孔设计以形成第三通孔141，开孔时能够采用化学蚀刻工艺，开孔后再将盖板本体140上的第三通孔141与粘接层130上的第二通孔131对应并贴合至粘接层130上。本申请的实施例中，通过将第三通孔141的侧壁相对于第二通孔131的侧壁而言进行内缩设计，还能够避免盖板本体140贴合过程中因贴合误差而导致盖板本体140的第三通孔141的侧壁伸出于粘接层130的第二通孔131的侧壁内，从而导致遮光层120无法对盖板本体140上第三通孔141的边缘结构进行有效遮挡，进而影响成像和显示品质。
可选的，如图3所示，复合盖板100还包括填充层150，填充层150设置在第一通孔121内，粘接层130覆盖遮光层120和填充层150。即遮光层120和填充层150在保护层110的第二表面112对应摄像区S1和遮光区S2的位置为整面设置，粘接层130直接整面覆盖在遮光层120、填充层150和保护层110上，以使盖板本体140与粘接层130为整面粘接，有利于提高盖板本体140的粘接稳定性，从而改善复合盖板100整体的结构稳定性。
其中，在第一表面111朝向第二表面112的方向上，填充层150的厚度与遮光层120的厚度相等。即当填充层150填充至第一通孔121内后，填充层150背离保护层110的一侧与遮光层120背离保护层110的一侧齐平，从而使得盖板本体140贴合至粘接层130上后，遮光层120和填充层150同时在盖板本体140的作用下挤压保护层110，以进一步确保保护层110上对应遮光区S2和摄像区S1的位置朝远离盖板本体140的方向凸出所形成的凸出部113的厚度的均匀性，从而使得进入摄像区S1的入射光线在穿过保护层110和填充层150时不会产生光程差或者发生发散，进而能够避免入射光线发生光路畸变，改善复合盖板100贴合至显示模组200上后摄像区S1的成像品质。
在一些实施例中，填充层150填充第一通孔121的同时覆盖在遮光层120背离保护层110的一侧，粘接层130则覆盖填充层150。即填充层150的厚度的最大值为遮光层120的厚度与遮光层120上填充层150的厚度之和。通过将填充层150覆盖在遮光层120上，能够避免填充层150填充至第一通孔121中之后因固化收缩而导致填充层150的厚度小于遮光层120的厚度，以进一步确保保护层110上对应遮光区S2和摄像区S1的位置朝远离盖板本体140的方向凸出所形成的凸出部113的厚度的均匀性，从而使得进入摄像区S1的入射光线在穿过保护层110和填充层150时不会产生光程差或者发生发散，进而能够避免入射光线发生光路畸变，改善复合盖板100贴合至显示模组200上后摄像区S1的成像品质。
其中，在第一表面111朝向第二表面112的方向上，填充层150的厚度能够设置为大于或等于0.5微米且小于或等于20微米。若填充层150的厚度过小，则可能会导致填充层150在制作过程中由于制作精度的影响无法确保与遮光层120平齐；若填充层150的厚度过大，则会导致复合盖板100的整体厚度过大，既不利于显示装置10的轻薄化设计，也会导致入射光线依次穿过保护层110和填充层150之后的利用率降低，从而影响成像效果。
在实际制作过程中，能够将填充层150的厚度设置为0.5微米、1微米、2微米、5微米、10微米、15微米或者20微米等，其具体厚度值能够根据实际设计需求进行选择调整，此处并不做特殊限制。
对应的，在第一表面111朝向第二表面112的方向上，遮光层120的厚度能够设置为大于或等于0.5微米且小于或等于5微米。若遮光层120的厚度过小，则会导致遮光层120对下方膜层边缘结构的遮挡效果较差，影响成像和显示品质；若遮光层120的厚度过大，则会导致复合盖板100的整体厚度过大，既不利于显示装置10的轻薄化设计，也会导致填充层150的厚度过大，从而导致入射光线依次穿过保护层110和填充层150之后的利用率降低，进而影响成像效果。
在实际制作过程中，能够将遮光层120的厚度设置为0.5微米、1微米、2微米、3微米、4微米或者5微米等，其具体厚度值能够根据实际设计需求进行选择调整，此处并不做特殊限制。
需要说明的是，填充层150具有透光性，其具体材质能够选择可光固化或者热固化的透明酯类材料，以使入射光线依次穿过保护层110和填充层150后进入显示模组200的摄像孔260，从而进行成像。在制作填充层150时，填充层150可以采用先通过液体涂布流平再固化的形式，也可以采用直接贴附填充材料的形式，其具体形成方式能够根据实际制程工序进行选择调整，此处并不做特殊限制。
其次，本申请的实施例还提供一种显示装置，该显示装置包括复合盖板，该复合盖板的具体结构参照上述实施例，由于本显示装置采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
如图4和图5所示，显示装置10包括显示模组200和复合盖板100，复合盖板100贴合在显示模组200的出光面上，即复合盖板100位于显示模组200的出光侧，以对显示模组200进行保护。其中，显示模组200上开设有摄像孔260，摄像孔260内设置有摄像头270等光学元件，用于进行拍照或摄像等操作。显示模组200包括层叠设置的支撑层210、缓冲层220、背板230、显示面板240和偏光片250，复合盖板100通过光学胶层贴合至显示模组200的偏光片250上。
复合盖板100包括摄像区S1、至少部分包围摄像区S1的遮光区S2、以及至少部分包围遮光区S2的透光区S3。复合盖板100贴合至显示模组200上时，复合盖板100的摄像区S1对应显示模组200上的摄像孔260，以便于入射光线通过摄像区S1进入摄像孔260内。复合盖板100的遮光区S2用于对显示模组200上摄像孔260的边缘结构进行遮挡，以避免人眼直接观察到摄像孔260的边缘结构，影响成像和显示品质。复合盖板100的透光区S3则对应显示模组200的显示区，用于透射出显示模组200的显示画面，以确保显示装置10的正常显示。
具体的，复合盖板100包括依次设置的保护层110、遮光层120、粘接层130和盖板本体140。保护层110具有相对设置的第一表面111和第二表面112，遮光层120设置在第二表面112。遮光层120位于遮光区S2，遮光层120对应摄像区S1的位置形成有第一通孔121。盖板本体140背离粘接层130的一侧用于与显示模组200贴合。其中，保护层110对应遮光层120围合的区域沿第二表面112朝向第一表面111的方向凸出并形成凸出部113，凸出部113对应摄像区S1的部分在第一表面111朝向第二表面112的方向上的厚度处处相等。本申请通过将凸出部113上对应摄像区S1的部分设置为厚度均匀，能够避免进入摄像区S1的入射光线在穿过保护层110时产生光程差或者发生发散，从而避免入射光线发生光路畸变，改善复合盖板100贴合至显示模组200上后摄像区S1的成像品质。
以上对本申请的实施例所提供的一种复合盖板及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方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
