具体实施方式
为了获得使屏幕振动发声，通常在显示面板背离出光侧的侧面设置激励器，但是，对于透光性比较强的显示面板，例如在顶发射柔性OLED(有机电致发光二极管)面板，其衬底较薄，导致设置激励器的地方发黄，影响显 示质量。
由于在显示面板背离出光侧的侧面设置激励器容易导致影响显示质量，相关技术中将激励器设置在位于显示面板背面的缓冲结构上，具体可参考图10，显示屏模组包括显示面板13，显示面板13的出光侧依次设置偏光片11和玻璃盖板9，其中，玻璃盖板9和偏光片11之间通过第一光学透明胶层10粘接，显示面板13和偏光片11之间通过第二光学透明胶层12粘接，显示面板背离出光侧的侧面设有缓冲结构14，激励器7设置于缓冲结构14背离显示面板13的侧面。该结构方案虽然可以避免影响显示面板的显示质量，但是会导致屏幕发声质量大幅下降。
为此，本申请实施例公开了一种显示面板缓冲结构、显示屏模组及其制备方法、终端设备，用于一方面避免将激励器直接设置在显示面板上时影响显示质量，同时避免将激励器设置在缓冲结构上时导致发声质量下降，可以有效提高屏幕发声型显示面板的质量。
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。
具体的，首先参考图1至图9；其中，图1、2、4、5、7、8为截面图，图3、6、9为俯视图，图3、6、9中带有‘/’的标号表示多个结构，例如，图3中的标号‘1/3’表示第一遮光膜1和缓冲膜3两层结构层叠在一起，图6中的标号‘5/6’表示缓冲膜3的镂空结构6与第二散热膜4开设的通孔5交叠在一起。
本申请实施例提供的显示面板缓冲结构，用于设置于显示面板的背离出光侧的侧面，如图1至图3所示，该显示面板缓冲结构包括：
缓冲膜3，缓冲膜3具有用于容纳激励器7的镂空结构6；
第一遮光膜1，贴附于缓冲膜3的用于与显示面板接触的第一侧面，且在第一侧面所在平面的正投影覆盖镂空结构6在所述第一侧面所在平面的正投 影，第一遮光膜1与镂空结构6相对设置的部分用于与激励器固定。
其中，上述“镂空结构6”既可以是贯穿缓冲膜3中部的通孔，也可以是设置在缓冲膜3边缘，并且向缓冲膜3内部凹陷的内凹槽；缓冲膜3的材料包括但不限于泡棉和海绵，只要具有缓冲效果的材料即可。上述第一遮光膜1的正投影完全覆盖镂空结构6的正投影，且可以完全覆盖缓冲膜3的第一侧面。
在上述显示面板缓冲结构中，如图1至图3所示，第一遮光膜1贴附于缓冲膜3的用于与显示面板接触的第一侧面，当将显示面板缓冲结构安装于显示面板的背面时，第一遮光膜1背离缓冲膜3的侧面与显示面板贴合；由于缓冲膜3具有镂空结构6，且该镂空结构6被第一遮光膜1覆盖，可以将激励器7设置于镂空结构6中，并使激励器7与第一遮光膜1固定，如图7和图8所示，由于第一遮光膜1具有遮光效果，激励器7被第一遮光膜1遮挡，在显示面板的出光侧，用户不容易看到激励器7，也不易出现显示面板局部压痕与发黄的情况，同时第一遮光膜1还可以避免终端设备中的光源对显示面板产生影响；并且，由于激励器7是设置在镂空结构6内，激励器7振动产生的能量直接通过第一遮光膜1和显示面板中的衬底等膜层振动而发声，不会经过缓冲膜3，在能量向显示面板传输的过程中不会被缓冲膜3吸收，进而可以提高发声质量。因此，上述显示面板缓冲结构的设置，可以同时改善屏幕发声型显示屏模组的显示质量和发声质量，有效提高显示屏模组质量。
并且，由于缓冲膜3设有容纳激励器7的镂空结构6，将激励器7设置于镂空结构6时，激励器7和显示面板缓冲结构的总厚度降低，有利于实现轻薄化，例如，以激励器7的厚度为2.6mm为例，当缓冲膜3的厚度为0.1mm时，最终显示面板缓冲结构和激励器7的总厚度能够降低0.1mm。
另外，第一遮光膜1的材料包括但不限于黑色橡胶和黑色布料，并且为了使得第一遮光膜1与显示面板贴合时第一遮光膜1不鼓泡，如图2所述，可以在第一遮光膜1的用于与显示面板结合的侧面设置栅状凸起结构11，由于具有栅状凸起结构11，第一遮光膜1和显示面板之间的气体可以经过凸起 结构之间的沟状结构排出，既能保证第一遮光膜1与显示面板贴合，又不容易鼓泡，例如，可以使用网格胶作为第一遮光膜1，具体的，网格胶厚度可以为30μm左右。
在上述显示面板缓冲结构中，第一遮光膜1可以直接与缓冲膜3贴合，也可以在第一遮光膜1和缓冲膜3之间设置其他膜层，该其他膜层可以不开设与镂空结构6对应的孔，将激励器7可以直接固定在该其他膜层上，也可以对该其他膜层开设与镂空结构6对应的孔，使激励器7穿过镂空结构6并贴合在第一遮光膜1上。
其中，所述的“其他膜层”可以是第一散热膜2，该第一散热膜2可以是像图4一样设置在第一遮光膜1和缓冲膜3之间，也可以像图5一样，将第一散热膜2设置在第一遮光膜1背离缓冲膜3的一侧；第一散热膜2的设置有利于显示面板散热，避免显示面板中积聚过多热量，该第一散热膜2包括但不限于铜箔、银箔、铝箔和石墨烯膜，同时，该第一散热膜2具有一定的遮光作用，可以进一步避免终端设备内的光源对显示面板的影响，以及对激励器进行遮挡，防止激励器影响显示面板的显示效果。
具体的，第一散热膜2为铜箔，厚度约为30μm-50μm，例如，具体可以为30μm，35μm，40μm，45μm，50μm。
如图4和图5所示，缓冲膜3中的与第一侧面相对设置的第二侧面设有第二散热膜4。
具体的，第二散热膜4在缓冲膜3的第二侧面所在平面的正投影与镂空结构6在第二侧面所在平面的正投影不重叠，即可以如图4至图6所示，在第二散热膜4与镂空结构6相对的位置开设贯穿通孔5，激励器穿过贯穿通孔5进入镂空结构6，也可以是，第二散热膜4的边缘没有延伸至镂空结构6处，可以理解为镂空结构6在缓冲膜3的第二侧面的正投影位于第二散热膜4在缓冲膜3的第二侧面的正投影以外；其中，第二散热膜4可以将显示面板散发至缓冲膜3中的热量尽快导出至显示屏模组外，避免在缓冲膜3内的热量积聚，同时，当缓冲膜3的第一侧面一侧具有第一散热膜2时，第一散热膜2 和第二散热膜4配合，更能够加快排出显示面板内的热量，提升显示面板性能。
其中，第二散热膜4包括但不限于铜箔、银箔、铝箔和石墨烯膜。
在上述显示面板缓冲结构中，为了进一步避免终端设备内的光源对显示面板的显示效果影响，如图8所示，缓冲膜3与第一侧面相对设置的第二侧面可以设有第二遮光膜8。
其中，第二遮光膜8在第二侧面所在平面的正投影与镂空结构6在第二侧面所在平面的正投影不重叠，即如图9所示，第二遮光膜8可以是具有与镂空结构6相对的通孔80，也可以是第二遮光膜8没有延伸至镂空结构6，第二遮光膜8的材质可以是橡胶和黑色布料等。
当具有第二散热膜4时，第二遮光膜8的位置既可以如图8所示，设置在第二散热膜4背离缓冲膜3的侧面，也可以设置在第二散热膜4和缓冲膜3之间。
基于相同的发明构思，本申请实施例提供一种显示屏模组，参考图11所示，显示屏模组包括：显示面板13、激励器7和如上面提供的显示面板缓冲结构；其中，
显示面板缓冲结构中的第一遮光膜1贴附于显示面板13的背离出光侧的侧面；
激励器7设置于镂空结构6中，且与第一遮光膜1固定。
具体可参考图11，显示屏模组包括显示面板13，显示面板13的出光侧依次设置偏光片11和玻璃盖板9，其中，玻璃盖板9和偏光片11之间通过第一光学透明胶层10粘接，显示面板13和偏光片11之间通过第二光学透明胶层12粘接，显示面板13背离出光侧的侧面依次设有第一遮光膜1、第一散热膜2、缓冲膜3和第二散热膜4，第一遮光膜1、第一散热膜2、缓冲膜3和第二散热膜4形成如前所述的显示面板缓冲结构，缓冲膜3具有镂空结构6，第二散热膜4具有与镂空结构6相对设置的贯穿通孔5，将激励器7设置于镂空结构6中，并将激励器7与第一散热膜2固定粘接。
在上述显示屏模组中，显示面板缓冲结构中第一遮光膜1贴附于缓冲膜3的用于与显示面板13接触的第一侧面，当将显示面板缓冲结构安装于显示面板13的背面时，第一遮光膜1背离缓冲膜3的侧面与显示面板13贴合；由于缓冲膜3具有镂空结构6，且该镂空结构6被第一遮光膜1覆盖，可以将激励器7设置于镂空结构6中，并使激励器7与第一遮光膜1固定，由于第一遮光膜1具有遮光效果，激励器7被第一遮光膜1遮挡，在显示面板13的出光侧，用户不容易看到激励器7，也就不易出现显示面板13局部发黄的情况；并且，由于激励器7是设置在镂空结构6内，激励器7振动产生的能量直接通过第一遮光膜1和显示面板13中的衬底等膜层振动而发声，不会经过缓冲膜3，在能量向显示面板13传输的过程中不会被缓冲膜3吸收，进而提高了发声质量；并且，由于缓冲膜3设有容纳激励器7的镂空结构6，将激励器7设置于镂空结构6时，激励器7和显示面板缓冲结构的总厚度降低，有利于实现显示屏模组的轻薄化。
另外，如图8所示，为了使激励器7中的热量充分散发出来，激励器7与镂空结构6的侧壁之间填充有散热胶15，该散热胶15可以是导电胶。
另外，镂空结构6在显示面板13上的正投影的中心点距离显示面板13的任一边缘的距离大于等于约5mm，例如，可以是5mm、6mm、7mm、8mm、10mm、15mm、20mm、25mm和30mm等；当镂空结构距离显示面板13的任一边缘的距离小于5mm时，由于激励器7距离显示面板13的边缘过近，显示面板13的边缘振动加剧，发热，进而温度升高，第一遮光膜1在这种情况下遮光效果会变差，进而又会导致用户在观看该显示屏模组时激励器7的位置出现发黄的情况。
具体地，为了方便用户接听方便，可以使镂空结构6在显示面板13上的正投影S位于显示面板13的顶边131附近，例如，参考图12，显示面板13包括相对设置的顶边131和底边132；镂空结构6在显示面板13上的正投影S的中心点至显示面板13的顶边131的距离约为5mm至25mm，例如，可以是5mm、6mm、7mm、8mm、9mm、10mm、15mm、20mm和25mm等；沿 与顶边131平行的方向，镂空结构6正投影S的中心点至显示面板13的顶边131的中垂线133的距离约0mm至20mm，例如，可以是，0mm、3mm、5mm、9mm、10mm、15mm和20mm。
需要说明的是，本申请实施例的数值范围中，涉及到‘约’或‘大约’的描述，是指在中心数值范围内可以具有一定的波动；例如，可以在上下5％的范围内波动，具体的，“约5mm”指的是可以在4.75mm-5.25mm的范围内波动。本申请中所述的‘显示面板的顶边’是指显示面板顶部边缘包括的一段直线段，以手机模组为例，其显示面板的边角一般为圆弧角，此时，该显示面板的顶边是指两端圆弧角之间的一段直线段。
作为其中一个具体的实施例，如图12所示，镂空结构6在显示面板13上的正投影S至显示面板13的顶边131的距离约为5mm；且镂空结构6在显示面板13上的正投影S位于显示面板13的中垂线133上。
需要说明的是，镂空结构6的位置不限于该区域，具体可以根据激励器7与其他器件的相互影响进行调节，例如，激励器7发热较大，影响其他器件的性能，或者，其他器件对激励器7有电磁干扰，为了避免激励器7与其他器件的这些相互影响，在实际应用中，激励器7(即镂空结构6)的位置可以根据上述其他器件的位置调节。
此外，在图12中，镂空结构6在显示面板13上的正投影S呈圆形，在实际应用中镂空结构6不限于上述形状，例如，镂空结构6在显示面板13上的正投影S还可以呈椭圆形、多边形(如三角形、矩形、梯形和平行四边形等)和其它不规则图形。
基于相同的发明构思，本申请实施例提供一种显示屏模组制备方法，至少包括以下步骤：
在显示面板13背离出光侧的侧面贴附如上述技术方案的显示面板缓冲结构；
将激励器7固定于镂空结构6中，并使激励器7与第一遮光膜1固定。
在上述显示屏模组制备方法中，将显示面板缓冲结构贴附在显示面板13 上，再将激励器7固定于镂空结构6中，并使激励器7与第一遮光膜1固定；遮光膜可以遮挡住激励器7，用户不容易看到显示面板13与激励器7处相对的位置发黄的情况；另外，激励器7产生的振动在传递时，直接通过第一遮光膜1将能量传递给显示面板13中的衬底等膜层，不会经过缓冲膜3，能量也就不容易被缓冲膜3吸收，所以，屏幕发声质量得到大幅提高；并且，由于缓冲膜3设有容纳激励器7的镂空结构6，将激励器7设置于镂空结构6时，激励器7和显示面板缓冲结构的总厚度降低，有利于实现轻薄化。
另外，本申请实施例提供的显示屏模组制备方法，还包括在激励器7与镂空结构6的侧壁之间填充散热胶，以提高激励器7的散热效率。
基于相同的发明构思，本申请实施例还提供了一种终端设备，包括前述的显示屏模组。
在上述终端设备中，如图11所示，显示面板缓冲结构的第一遮光膜1贴附于缓冲膜3的用于与显示面板13接触的第一侧面，当将显示面板缓冲结构安装于显示面板13背面时，第一遮光膜1背离缓冲膜3的侧面与显示面板13贴合；由于缓冲膜3具有镂空结构6，且该镂空结构6被第一遮光膜1覆盖，可以将激励器7设置于镂空结构6中，并使激励器7与第一遮光膜1固定，由于第一遮光膜1具有遮光效果，激励器7被第一遮光膜1遮挡，在显示面板13的出光侧，用户不容易看到激励器7，也就不易出现显示面板13局部发黄的情况；并且，由于激励器7是设置在镂空结构6内，激励器7振动产生的能量直接通过第一遮光膜1和显示面板13中的衬底等膜层振动而发声，不会经过缓冲膜3，在能量向显示面板13中的传输的过程中不会被缓冲膜3吸收，进而提高了发声质量；并且，由于缓冲膜3设有容纳激励器7的镂空结构6，将激励器7设置于镂空结构6时，激励器7和显示面板缓冲结构的总厚度降低，有利于实现轻薄化。
显然，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在 内。
