近年来，在OLED显示屏的制程中，显示区开孔(AA Hole)技术被大量应用。具体的，本申请发明人发现，在OLED显示屏的制程中，设有模组通孔的结构组件一般需要通过保护膜进行保护，该保护膜往往在终端组装工序之前就需要撕下来，这样，很容易导致结构组件的通孔内脏污，进而对于后续产品良率造成影响。例如，在OLED显示屏的制程中，在客户终端装摄像头之前，会对OLED膜层通孔进行多道撕膜检查工序，如贴合精度检查，从而，会将贴覆在散热模组(SCF)上的保护膜撕掉，这样很容易导致AAHole脏污，且不易清洁，从而给摄像头模组组装造成很大困难，且容易导致产品良率受到影响。
鉴于此，本申请提供一种保护膜模组和显示组件及其制备方法、散热组件，用以改善显示产品制程中各结构组件的保护良率的问题。
下面将结合本申请实施例中的附图，对本申请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，本领域普通技术人员在没有做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。
如图1至图3所示，本申请实施例提供了一种保护膜模组，该保护膜模组包括基材层1和第一粘附层2，如图4所示，其中：
基材层1，被配置为覆盖显示产品的结构组件4；结构组件4包括贯穿的第一开口40；
第一粘附层2，贴附于基材层1朝向结构组件4的一侧表面，且可相对于基材层1剥离，第一粘附层2的尺寸大于结构组件4的第一开口40的尺寸，被配置为覆盖结构组件4的第一开口40。
上述保护膜模组可以贴附于显示产品的结构组件4上，以保护显示产品的结构组件4；具体的，该保护膜模组包括基材层1以及贴附在基材层1上用于覆盖结构组件4的第一开口40的第一粘附层2，该第一粘附层2可相对于基材层1剥离，因此，显示产品制程中，在终端组装工序之前需要撕膜时，可以先将基材层1撕下，即将基材层1从结构组件4和第一粘附层2上剥离，并保留第一粘附层2，直到需要暴露结构组件4的第一开口40时再将第一粘附层2从结构组件4上剥离，这样，可以有效避免结构组件4的第一开口40脏污，从而在后续组装时不需要清洁第一开口40并可以保证组装产品的良率。
例如，如图4所示，显示产品的结构组件4可以包括散热模组5，该散热模组5设有第一开口40；具体的，散热模组5用于与显示模组贴合，其第一开口40用于暴露显示模组的显示区开孔(AA Hole)，第一开口40和显示区开孔(AA Hole)可以用于容纳组装功能模组(如摄像头模组)。本申请提供的保护膜模组可以保护散热模组5；例如，在显示组件制程中，首先可以将本申请提供的保护膜模组贴附于散热模组5的一侧，然后将散热模组5另一侧贴附于显示模组上，此时保护膜模组可以在散热模组5一侧形成保护。在终端组装之前的检查工序中，例如，检查第一开口40和显示区开孔(AA Hole)的贴合精度和/或检查散热模组5和显示模组的外观时，可以撕下保护膜模组的基材层1而保留第一粘附层2，直到在第一开口40处组装摄像头模组时，再将第一粘附层2撕掉，这样在组装摄像头模组之前，第一粘附层2一直覆盖第一开口40处，可以避免第一开口40和显示区开孔(AA Hole)赃污，从而在组装摄像头模组前不需要清洁第一开口40和显示区开孔(AA Hole)处，并且可以保证组装产品的良率。
本申请中，‘粘合’和‘粘附’是指通过胶粘材料将两者粘在一起。‘贴合’和‘贴附’是指两者贴在一起，包括但并不限于采用粘胶材料将两者贴在一起，也可以采用其他方式(如静电吸附)的方式使两者贴在一起。
如图4所示，一些实施例中，本申请提供保护膜模组中，第一粘附层2被配置为粘附在结构组件4围绕第一开口40的边缘。即当保护膜模组贴附于 显示产品的结构组件4上时，第一粘附层2完全覆盖结构组件4的第一开口40且第一粘附层2的边缘与结构组件4围绕第一开口40的边缘粘合。
如图2和图3所示，一些实施例中，本申请提供的保护膜模组还可以包括第二粘附层3，第二粘附层3与第一粘附层2位于基材层1的同一侧，第二粘附层3贴附于基材层1。
具体的，第二粘附层3围绕第一粘附层2设置，被配置为覆盖结构组件4的第一开口40以外的部分，如图2至图4所示，即当保护膜模组贴附于显示产品的结构组件4上时，第二粘附层3贴附于结构组件4的第一开口40以外的部分。
具体的，第二粘附层3与第一粘附层2均粘附于基材层1。
具体的，如图2所示，第二粘附层3背离基材层1的一侧表面与第一粘附层2背离基材层1的一侧表面大致齐平。
如图2至图4所示，第二粘附层3与第一粘附层2位于基材层1的同一侧，且围绕第一粘附层2设置；将保护膜模组贴附于显示产品的结构组件4上，具体可以包括将第二粘附层3背离基材层1的一侧表面与第一粘附层2背离基材层1的一侧表面分别粘贴于结构组件4上。第二粘附层3的设置，可以避免由于第一粘附层2与基材层1存在段差(第一粘附层2表面与基材层1表面存在高度上的差距)而导致第一粘附层2周边出现较大范围的贴合气泡区，从而可以使得保护膜模组的贴附效果比较好。
当然，本申请提供的保护膜模组也可以不设置第二粘附层，如图1所示，此时，将保护膜模组贴附于显示产品的结构组件上，具体可以是将第一粘附层2背离基材层1的一侧表面以及基材层1上除设置第一粘附层2之外的部分表面分别与结构组件粘合。具体的，此时，可以通过尽量减小第一粘附层2的厚度来避免第一粘附层2周边出现较大范围的贴合气泡区，从而改善保护膜模组的贴附效果。
如图2和图3所示，一些实施例中，第二粘附层3与第一粘附层2之间具有间隙。这样，可以方便分别进行第二粘附层3与第一粘附层2的制作， 避免第二粘附层3与第一粘附层2出现交叠。
具体的，第二粘附层3与第一粘附层2之间的间隙大小由实际制作水平和精度决定，原则上该间隙可以设计的尽量小。
如图1和图2所示，一些实施例中，沿远离基材层1的方向上，第一粘附层2依次包括第一UV减黏胶层21、第一保护膜层22、第一胶层23；第一UV减黏胶层21被配置为经紫外光(UV)照射后粘性小于第一胶层23的粘性。
具体的，如图4所示，第一粘附层2中，第一UV减黏胶层21用于粘附于基材层1，第一胶层23用于粘附于显示产品的结构组件4；经紫外光照射后，第一UV减黏胶层21的粘性小于第一胶层23的粘性，此时，将基材层1从结构组件4上撕下时，基材层1可以与第一UV减黏胶层21发生剥离，而第一胶层23不会从结构组件4上剥离，从而第一粘附层2可以继续粘附在结构组件4上并对结构组件4的第一开口40进行覆盖保护。
如图2所示，一些实施例中，沿远离基材层1的方向上，第二粘附层3依次包括第二胶层31、第二保护膜层32、第三胶层33；第三胶层33的粘性小于第二胶层31的粘性。
具体的，如图4所示，第二粘附层3中，第二胶层31用于粘附于基材层1，第三胶层33用于粘附于显示产品的结构组件4；由于第三胶层33的粘性小于第二胶层31的粘性，则将基材层1从结构组件4上撕下时，基材层1不会与第二胶层31发生剥离，而第三胶层33会从结构组件4上剥离，从而第二粘附层3将随着基材层1脱离结构组件4。
一些实施例中，第一胶层23的粘性大于第三胶层33的粘性且小于第二胶层31的粘性。这样，将基材层1从结构组件4上撕下时，可以使得第二粘附层3更容易随基材层1脱离结构组件4，而第一粘附层2更不容易脱离结构组件4。
一些实施例中，第一UV减黏胶层21的粘性大于第二胶层31的粘性。即未经紫外光照射时，第一UV减黏胶层21的粘性大于第二胶层31的粘性， 这样，可以避免在使用保护膜模组之前或者在撕膜操作之前，第一粘附层2从基材层1上剥离脱落。
一些实施例中，第一UV减黏胶层21的粘性可以为700gf/inch-1500gf/inch，第一胶层23的粘性可以为50gf/inch-100gf/inch，第二胶层31的粘性可以为300gf/inch-600gf/inch，第三胶层33的粘性可以为5gf/inch-20gf/inch。
一些实施例中，第三胶层33的材料为UV减黏胶。
如图4所示，第三胶层33用于与显示产品的结构组件4粘合，第三胶层33的材料为UV减黏胶，在将基材层1从结构组件4上撕下之前，采用紫外光对第三胶层33进行照射可以使得其粘性降低，进而可以使得第三胶层33更容易从结构组件4上剥离，从而使得第二粘附层3更容易随着基材层1脱离结构组件4。
一些实施例中，基材层1的材料可以为聚酯膜(PET)；第一保护膜层22和第二保护膜层32的材料也可以为聚酯膜(PET)。
示例性的，基材层1和第一保护膜层22的材料可以为无色透明聚酯膜，第二保护膜层32的材料为蓝色透明聚酯膜。
如图4所示，基材层1和第一保护膜层22为无色透明聚酯膜，可以透过基材层1和第一粘附层2对结构组件4的第一开口40进行观察，从而，有利于检查结构组件4各膜层开口以及显示区开口(AA Hole)的对齐情况。
如图4所示，一些实施例中，基材层1可以包括超出结构组件4的边沿的耳部11。
具体的，基材层1的耳部11不设有胶层和粘附层，可以通过夹持耳部11施加拉力从而将基材层1从结构组件4上撕下。
基于与本申请实施例提供的保护膜模组相同的发明构思，本申请实施例还提供一种保护膜模组的制备方法，该方法包括：
如图1所示，在基材层1朝向显示产品的结构组件4的一侧表面贴附第一粘附层2，第一粘附层2可相对于基材层1剥离；其中，基材层1被配置为 覆盖显示产品的结构组件，结构组件包括贯穿的第一开口；第一粘附层的尺寸大于结构组件的第一开口的尺寸，被配置为覆盖结构组件的第一开口。
一些实施例中，在基材层朝向显示产品的结构组件的一侧表面贴附第一粘附层之前，还可以包括：
如图2和图3所示，在基材层1朝向显示产品的结构组件的一侧表面贴附第二粘附层3；在第二粘附层3靠近结构组件的第一开口处对第二粘附层3进行打孔，以在第二粘附层3中形成暴露第一开口的通孔30。
进一步地，在基材层朝向显示产品的结构组件的一侧表面设置第一粘附层，具体包括：
如图3所示，在第二粘附层3的通孔30内贴附第一粘附层2。
具体的，通过本申请提供的保护膜模组的制备方法获得的保护膜模组，可以与本申请提供的保护膜模组具有相同的实施例和有益效果，此处不再一一赘述。
如图4所示，本申请实施例还提供一种散热组件，该散热组件包括散热模组5以及上述任一项的保护膜模组；具体的，显示产品的结构组件4包括上述散热模组5，该散热模组5设有第一开口40。
示例性的，如图4所示，保护膜模组中，基材层1覆盖散热模组5，第一粘附层2贴附于基材层1朝向散热模组5的一侧表面，第一粘附层2的尺寸大于散热模组5的第一开口40的尺寸，且粘附在散热模组5围绕第一开口40的边缘。
如图4所示，一些实施例中，沿远离保护膜模组的方向上，散热模组5可以依次包括金属散热层51、PET膜层52、泡棉层53和网格胶层54。
示例性的，金属散热层51可以为铜箔。保护膜模组贴附在金属散热层51上。
如图5和图6所示，本申请实施例还提供一种显示组件，该显示组件包括显示模组6以及上述任一项所述的散热组件；散热组件中，散热模组5背离保护膜模组的一侧贴附于显示模组6上。

示例性的，如图6所示，散热模组5的第一开口40被配置为暴露出指纹感应器的感应区；即，可以将指纹感应器设置在散热模组5的第一开口40处，指纹感应器可以透过第一开口40感应从显示模组6一侧入射的光线，从而实现指纹识别功能。具体的，显示模组6可以为OLED透明显示模组，即光线可以透过显示模组6到达位于第一开口40处的指纹感应器。
示例性的，本申请实施例提供的显示组件，还可以包括位于所述显示模组6背离所述散热模组5一侧的玻璃盖板(图中未示出)。
具体的，本申请实施例的显示组件中，保护膜模组在显示组件的一侧形成保护。该显示组件进入显示产品组装工序之前，需要先进行检查工序，例如，如图5所示，需要检查散热组件第一开口40和显示模组6的显示区开孔(第二开口60)的贴合精度以及检查散热模组5和显示模组6的外观，此时，可以撕掉保护膜模组的基材层1和第二粘附层3并保留下第一粘附层2以进行检查，由于第一粘附层2一直覆盖第一开口40处，可以避免第一开口40和第二开口(AA Hole)60赃污；直至后续需要在第一开口40处组装功能模组(如摄像头模组)时，再将第一粘附层2撕掉，由于第一开口40和第二开口(AA Hole)60在前面的流程中没有受到污染，从而在组装之前不需要清洁第一开口40和第二开口(AA Hole)60处，并且可以保证组装后产品的良率。
如图7所示，本申请另一实施例还提供一种显示组件，该显示组件包括：
显示模组6；
散热模组5，贴附于显示模组6的一侧，散热模组5设有第一开口40；

具体的，如图7所示，第一粘附层2粘附在散热模组5围绕第一开口40 的边缘。
具体的，本实施例提供的显示组件中第一粘附层2的具体实施例可以与上述任一项的保护膜模组中的第一粘附层2的具体实施例相同。例如，如图7所示，本实施例提供的显示组件中，沿远离散热模组5的方向上，第一粘附层2可以依次包括第一UV减黏胶层21、第一保护膜层22、第一胶层23；第一UV减黏胶层21被配置为经紫外光(UV)照射后粘性小于第一胶层23的粘性。
本申请实施例的显示组件可以为在第一开口处组装摄像头模组前的一种产品形态，具体可以是如图5和图6所示的显示组件中保护膜模组的基材层1和第二粘附层3从散热模组5上剥离后的产品形态。
