具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域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，都属于本发明保护的范围。
请参阅图1，本发明提供的一种触摸显示屏包括：触摸组件1、缓冲层2和显示组件3。
下面对图1所示触摸显示屏的各组件进行详细介绍，请参阅图2：
触摸组件1包括第一表面11以及与第一表面11相反的第二表面12；
缓冲层2由透明弹性材料组成，填充在触摸组件1与显示组件3之间，包括第三表面21以及与第三表面21相反的第四表面22，第三表面21与第二表面12相对设置；
显示组件3包括显示面31以及与显示面相反的背光面32，显示面31与第四表面22相对设置。
其中，触摸组件1的材料为蓝宝石、红宝石或铝硅钢化玻璃，其厚度优选为0.5毫米到2毫米之间的任意值。
其中，缓冲层2的厚度优选为0.5毫米到2毫米之间的任意值，具体数值此处不作限定。缓冲层2中的透明弹性材料可以是聚对苯二甲酸乙二醇酯(Polyethylene Terephthalate，简称PET)、聚氯乙烯(Polyvinyl Chloride，简称PVC)、聚乙烯(Polyethylene，简称PE)或聚苯乙烯(Polystyrene，简称PS)，还可以是其他透明弹性聚合物，或是以上材料组成的复合材料，具体此处不作限定。
下面对缓冲层2在外力冲击下的缓冲过程进行介绍：
当压力作用于触摸组件1的第一表面11时，触摸组件1立即将压力传导至缓冲层2，由于缓冲层2中透明弹性材料的强度低，在压力的作用下立即发生形变，同时产生的弹力能够对触摸组件1形成支撑，分担了压力对触摸组件1的冲击，从而有效保护触摸组件1，因此本发明提供的触摸显示屏比现有技术中的触摸显示屏具备更好的抗冲击性能。
可选的，在本发明的另一个实施例中，请参阅图3，触摸显示屏还包括粘性材料层4，粘性材料层4的两侧分别与第二表面12以及第三表面21粘接，使触摸组件1和缓冲层2贴合。
具体的，粘性材料层4由粘性材料固化而成，粘性材料可以将触摸组件1和缓冲层2牢牢固定在一起，同时粘性材料的强度不高，受到压力时可以变形，减少压力对触摸组件1的冲击，因此可以提高触摸显示屏的抗冲击能力。其中，粘性材料可以是环氧胶粘剂或聚氨酯胶粘剂，还可以是其他粘合剂，具体此处不作限定。粘性材料层的厚度一般为几微米，例如5μm，具体数值此处不作限定。
在实际应用中，触摸显示屏一般设有显示屏框体，下面对固定在显示屏框体中的触摸显示屏进行介绍，请参阅图4，本发明提供的另一种触摸显示屏包括：触摸组件1、缓冲层2和显示组件3，粘性材料层4和显示屏框体5。
其中，触摸组件1、缓冲层2、显示组件3和粘性材料层4的组成以及相互之间的连接关系与图1、图2或图3所示实施例或可选实施例相似，此处不再赘述。
下面对显示屏框体5进行详细介绍，请参阅图4，显示屏框体5包括通槽52、边框51和基座53；其中，边框51一体成型于通槽52的顶部，边框51 的内侧边缘和触摸组件1的形状一致；
当触摸组件1嵌设于边框51内时，触摸组件1、边框51、通槽52和基座53形成密闭空腔，以封装显示组件3和缓冲层2。
其中，通槽52固定在基座53上。
本实施例中，显示屏框体的材料一般为聚碳酸酯(Polycarbonate，简称PC)或丙烯腈-丁二烯-苯乙烯共聚物(Acrylonitrile butadiene Styrene copolymers，简称ABS)，具备很高的硬度和强度，可以保护触摸组件1抵抗来自侧面或底面的外力冲击，能够有效保护触摸显示屏。
需要说明的是，在实际应用中，如果触摸显示屏不需要利用粘性材料固定触摸组件1和缓冲层2，那么也可以没有粘性材料层4，具体此处不作限定。
进一步的，边框51与触摸组件1的嵌接处填充有透明弹性材料。
具体的，边框51的内侧边缘与触摸组件1的边缘之间填充有透明弹性材料，当压力作用于通槽52或边框51时，透明弹性材料可以为触摸组件1分担来自侧面的压力冲击，因此能够有效保护触摸显示屏。其中，透明弹性材料与图2所示实施例中的透明弹性材料相同，此处不再赘述。
下面对固定在另一种显示屏框体中的触摸显示屏进行介绍，请参阅图6，本发明提供的另一种触摸显示屏包括：
触摸组件1、缓冲层2、显示组件3，粘性材料层4和显示屏框体6。
其中，触摸组件1、缓冲层2、显示组件3和粘性材料层4的组成以及相互之间的连接关系与图1、图2或图3所示实施例或可选实施例相似，此处不再赘述。
下面对显示框体6进行详细介绍，请参阅图7，显示屏框体6包括通槽61和基座62；
当通槽61固定于基座62时，通槽61和基座62形成收容槽，收容槽用于收容显示组件3和缓冲层2；触摸组件1与通槽61顶部的横截面形状一致，固定于通槽61的顶部。
下面对通槽61进行详细介绍，请参阅图8，在本发明的另一个实施例中，通槽61包括上通槽611和下通槽612；
下通槽612固定于基座62，下通槽612与显示组件3的形状一致；
上通槽611与缓冲层2的形状一致，上通槽611的高度与缓冲层2的厚度一致，上通槽611的槽壁厚度小于下通槽612的槽壁厚度。
具体的，下通槽612的槽壁高度高于基座62的高度，当下通槽612固定在基座62上时，形成一个收容槽，可以容纳显示组件3。
因为上通槽611的槽壁厚度小于下通槽612的槽壁厚度，所以在上通槽611的底部，由下通槽612的顶部构成一个环状支撑平台，可以对缓冲层2进行支撑。
在本发明的另一个实施例中，通槽61与缓冲层2的嵌接处填充有透明弹性材料。
具体的，上通槽611的槽壁与缓冲层2的边缘之间填充有透明弹性材料。当压力作用于通槽61时，透明弹性材料可以为触摸组件1分担来自侧面的压力冲击，因此能够有效保护触摸显示屏。其中，透明弹性材料可参阅图2所示实施例中的透明弹性材料，此处不再赘述。
以上所述，以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，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发明各实施例技术方案的范围。
