显示装置的承载部件的粘贴结构和显示装置 技术领域
本发明涉及显示技术领域，具体地，涉及一种显示装置的承载部件的粘贴结构和一种显示装置。
背景技术
在显示技术领域，特别是在显示装置的承载部件中，粘贴工艺被广泛应用。
传统的粘贴工艺通常只使用一种粘结胶，如胶水或双面胶。双面胶的抗塑性变形性能、耐气候性能和抗冲击性能强，但粘贴强度弱。胶水的粘贴强度强，但抗塑性变形性能、抗冲击性能和耐气候性能弱。这使得单纯使用双面胶进行粘贴的粘贴结构，在外力的作用下，容易产生开胶的问题，使粘贴结构的粘结强度严重不足。单纯使用胶水进行粘贴的粘贴结构，由于胶水粘结后容易在脆性应力作用下产生开裂，所以使得粘贴结构在粘贴后的韧性不足，严重影响显示装置中承载部件的牢固性能。
另外，单纯使用胶水进行粘贴时，容易产生溢胶，所以在单纯使用胶水进行粘贴时通常需要专门的治具参与，并且预贴合时间较长。同时，溢胶还会影响到粘贴结构外观的美观度。

具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明所提供的一种显示装置的承载部件的粘贴结构和显示装置作进一步详细描述。
第一实施例
本实施例提供一种显示装置的承载部件的粘贴结构，如图1所示，该粘贴结构包括第一结构件1、第二结构件2以及将第一结构件1和第二结构件2粘结在一起的粘结胶3。粘结胶3包括第一种胶31和第二种胶32，第一种胶31的抗变形性能优于第二种胶32，第二种胶32的粘结性能优于第一种胶31。
该粘贴结构通过采用第一种胶31和第二种胶32共同粘贴，使两种不同胶的优势性能和弱势性能能够互补，从而不仅提高了该粘贴结构的粘结强度，同时还提高了该粘贴结构的抗变形强度。粘贴结构抗变形强度的提高，能使其具有更好的柔韧性，从而也提高了其抗冲击强度和耐气候性能，进而使粘贴结构不会因为粘结胶的脆性问题和强度问题而产生开胶和开裂，增强了包括该粘贴结构的承载部件的牢固性。
本实施例中，在第一结构件1和第二结构件2的对应粘贴区域(所述对应粘贴区域例如为图1所示的第一结构件1和第二结构件2的互相面对的两个表面上的对应区域)，第二种胶32设置在粘贴区域的中心区域，第一种胶31设置在粘贴区域的边缘区域，所述中心区域和所述边缘区域可以不互相重叠。如此设置，不仅使第一种胶31和第二种胶32在粘贴结构中能同时发挥其粘贴优势，同时还对各自的粘贴弱势形成了互补，从而使该粘贴结构既能保证足够的粘结强度，又能保证足够的抗变形强度，进而避免粘贴结构出现开胶和开裂问题。
其中，设置在粘贴区域的边缘区域的第一种胶31可以完全包围在设置在粘贴区域的中心区域的第二种胶32的外围，如图2所示。第一种胶31可以为呈固体状态的胶，第二种胶32可以 为呈液体状态的胶。如此设置，在确保足够的粘结强度和抗变形强度的同时，第一种胶31能把第二种胶32隔绝在一个独立的空间内，从而避免第二种胶32溢出，进而提升了该粘贴结构的外观的美观度。
另外，采用第一种胶31和第二种胶32共同粘贴，相比于现有技术中单独采用第二种胶32进行粘贴的情况，由于第一种胶31的设置能够控制溢胶，所以不再需要专门的粘贴治具，同时，由于第一种胶31能够及时对第一结构件1和第二结构件2进行粘结，所以还缩短了粘贴的预贴合时间(在单独采用第二种胶32的情况下，由于第二种胶32的固化时间较长，所以预贴合时间较长)。
需要说明的是，第一种胶31也可以不对第二种胶32进行包围。由于第二种胶32设置在粘贴区域的中心区域，第一种胶31设置在粘贴区域的边缘区域，而且第二种胶32通常为粘稠状的液体，所以即使第一种胶31不对第二种胶32进行包围，第二种胶32在经过延展之后也通常不会溢出至粘贴区域以外，从而确保了粘贴结构的外观美观度。
本实施例中，第一种胶31和第二种胶32在粘贴区域的分布面积的比可以任意设置，只要最终确保第一结构件1和第二结构件2在经过两种胶粘结之后，能够确保足够的粘结强度和足够的抗变形强度即可。优选的第一种胶31和第二种胶32在粘贴区域的分布面积的比为1:1。
本实施例中，如图2所示，第二种胶32呈S型均匀分布。如此设置，一方面，能够在增加第二种胶32在延展后的粘贴面积的情况下，使第二种胶32不会溢出至粘贴区域之外，从而避免影响粘贴结构的外观；另一方面，能够在确保足够的粘结强度的情况下，减少第二种胶32的用量，从而降低该粘贴结构的粘贴成本。
本实施例中，第一种胶31呈网点状均匀分布。如此设置，一方面，能够在确保足够的抗变形强度的情况下，减少第一种胶 31的用量，从而降低该粘贴结构的粘贴成本；另一方面，由于第一种胶31为点状间隔分布，相对于面状分布，能够进一步增强经其粘结后的粘贴结构的柔韧性，从而使该粘贴结构更加不容易开胶。
需要说明的是，本实施例中，第一种胶31和第二种胶32的对应边缘可以相接触(即对接在一起)(如图3所示)，也可以不相接触，即两种胶的对应边缘相互间隔一定的距离，间隔区域为空气(如图2所示)。
另外，第二种胶32也可以呈网点状均匀分布，第一种胶31以任意形式分布(如图4所示)。或者，第一种胶31可以呈S型均匀分布，第二种胶32以任意形式分布。
另外需要说明的是，第一种胶31和第二种胶32的分布形状也可以是其它的形状，如矩形、三角形或多边形等。
本实施例中，第一种胶31可以是双面胶，第二种胶32可以是胶水。当然，第一种胶31还可以是其它的呈固体状态的胶，第二种胶32还可以是其它的呈液体状态的胶，对两种胶的具体材料不做限定，只要是能对第一结构件1和第二结构件2进行互补性粘贴的胶都在本发明的保护范围内。
第二实施例
本实施例提供一种显示装置的承载部件的粘贴结构，与第一实施例不同的是，如图5所示，设置在粘贴区域的边缘区域的第一种胶31局部包围在设置在粘贴区域的中心区域的第二种胶32的外围。
如此设置，在确保足够的粘结强度和抗变形强度的情况下，第一种胶31能对第二种胶32的局部外围进行包围，从而减少第二种胶32溢出，进而提升该粘贴结构的局部外观的美观度。
本实施例中显示装置的承载部件的粘贴结构的其他结构与第一实施例中的相同，此处不再赘述。
第三实施例
本实施例提供一种显示装置的承载部件的粘贴结构，与第一实施例不同的是，如图6所示，在第一结构件1和第二结构件2的对应粘贴区域，第一种胶31设置在粘贴区域的中心区域，第二种胶32设置在粘贴区域的边缘区域。
如此设置，同样不仅能使第一种胶31和第二种胶32在粘贴结构中同时发挥其粘贴优势，同时还对各自的粘贴弱势形成了互补，从而使该粘贴结构既能保证足够的粘结强度，又能保证足够的抗变形强度，进而避免粘贴结构出现开胶和开裂问题。
本实施例中，设置在粘贴区域的边缘区域的第二种胶32完全包围在设置在粘贴区域的中心区域的第一种胶31的外围。由于第一种胶31通常为呈固体状态的胶，第二种胶32通常为呈液体状态的胶。所以如此设置，虽然能够确保足够的粘结强度和抗变形强度，但由于第二种胶32分布在粘贴区域的边缘区域，所以第二种胶32可能会溢出，因此，本实施例中第一种胶31和第二种胶32的分布位置主要适用于对外观要求不高的粘贴结构。
需要说明的是，设置在粘贴区域的边缘区域的第二种胶32也可以局部包围在设置在粘贴区域的中心区域的第一种胶31的外围。
本实施例中显示装置的承载部件的粘贴结构的其他结构与第一实施例中的相同，此处不再赘述。
第四实施例
本实施例提供一种显示装置的承载部件的粘贴结构，与第一实施例至第三实施例不同的是，如图7所示，在第一结构件1和第二结构件2的对应粘贴区域，第一种胶31设置在粘贴区域的一侧区域，第二种胶32设置在粘贴区域的另一侧区域。
如此设置，同样不仅能使第一种胶31和第二种胶32在粘贴结构中同时发挥其粘贴优势，同时还对各自的粘贴弱势形成了互补，从而使该粘贴结构既能保证足够的粘结强度，又能保证足够 的抗变形强度，进而避免粘贴结构出现开胶和开裂问题，增强了该承载部件的牢固性。
本实施例中，所述一侧区域和所述另一侧区域的面积可以各占粘贴区域的面积的二分之一，且第一种胶31和第二种胶32的分布面积相等。如此设置，使第一结构件1和第二结构件2在经过两种胶粘结之后，能够确保足够的粘结强度和足够的抗变形强度，从而避免粘贴结构出现开胶和开裂问题。
需要说明的是，所述一侧区域和所述另一侧区域的面积也可以不相等，且第一种胶31和第二种胶32的分布面积也可以不相等，而是按照一定的比例设置。例如，第一种胶31和第二种胶32的分布面积的比为1:2或2:1等，只要能够最终确保粘贴结构具有足够的粘结强度和抗变形强度即可。
另外需要说明的是，由于第一种胶31通常为呈固体状态的胶，第二种胶32通常为呈液体状态的胶。上述设置，虽然能够确保粘贴结构具有足够的粘结强度和抗变形强度，但由于第二种胶32分布在粘贴区域的一侧，所以在第二种胶32的设置侧可能会出现溢胶，因此，本实施例中第一种胶31和第二种胶32的分布位置主要适用于对粘贴结构的一侧外观要求不高的粘贴结构。
本实施例中显示装置的承载部件的粘贴结构的其他结构与第一实施例中的相同，此处不再赘述。
根据第一至第四实施例中所提供的显示装置的承载部件的粘贴结构，通过采用第一种胶和第二种胶共同粘贴，使两种不同胶的优势性能和弱势性能能够互补，从而不仅提高了该粘贴结构的粘结强度，同时还提高了该粘贴结构的抗变形强度，因此也提高了其抗冲击强度和耐气候性能，进而使粘贴结构不会因为粘结胶的脆性问题和强度问题而产生开胶和开裂，增强了包括该粘贴结构的承载部件的牢固性。
第五实施例
本实施例提供一种显示装置，该显示装置包括第一至第四实 施例的任意一个中的显示装置的承载部件的粘贴结构。
本实施例中，粘贴结构中的第一结构件和第二结构件可以为显示装置中的两个金属件。
需要说明的是，粘贴结构中的第一结构件和第二结构件也可以为显示装置中的两个非金属件；或者，粘贴结构中的第一结构件和第二结构件中的一个为显示装置中的非金属件，另一个为显示装置中的金属件。即粘贴结构在显示装置中的应用范围很广，对各种金属件或非金属件均可进行粘贴。
通过采用第一至第四实施例的任意一个中的粘贴结构，提升了该显示装置的组装质量，从而也提升了该显示装置的品质。
该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
应当理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也属于本发明的保护范围。
