本申请实施例提供一种显示装置及显示终端。以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参阅图1，图1为现有技术中显示装置100的结构的示意图。
在图1的现有技术中，显示装置100包括显示面板本体10，显示面板本体10包括平板部FF1、弯折部FF2和焊盘部FF3，弯折部FF2位于平板部FF1和焊盘部FF2之间，弯折部FF2弯折后，焊盘部FF3位于平板部FF1的背侧，背板层11包括第一背板111和第二背板112，第一背板111设置于平板部FF1的背侧，第二背板112设置于焊盘部FF3朝向平板部FF1的一侧。平板部FF1和焊盘部FF3之间的膜层结构依次包括：第一背板111、缓冲与遮光层50、刚性支撑层12、双面胶带31、第二背板112。
背板层11通常为聚酰亚胺或PET材质，用于支撑显示面板本体10的作用；缓冲与遮光层通常为黑色泡棉材料（Foam），用于缓冲和遮光的作用；刚性支撑层通常为不锈钢材料（SUS），用于提供显示面板本体10平整的表面。
在现有技术中，缓冲与遮光层50的厚度非常厚，而这种泡棉大多数厚度在100微米-150微米，甚至更厚，才能满足缓冲和遮光的功能，厚度较大且会滋生其他类似褶皱的问题。因此现有显示装置中多层支撑层的设置使得显示装置存在厚度较厚的问题。
实施例一、
请参阅图2、图3，图2为本申请实施例提供的显示装置100的第一种弯折前的示意图，图3为本申请实施例提供的显示装置100的第一种弯折后的示意图。
本申请实施例提供了一种显示装置100，显示装置100包括：显示面板本体10、背板层11、刚性支撑层12。显示面板本体10包括平板部FF1、弯折部FF2和焊盘部FF3，弯折部FF2位于平板部FF1和焊盘部FF2之间，弯折部FF2弯折后，焊盘部FF3位于平板部FF1的背侧；背板层11包括第一背板111和第二背板112，第一背板111设置于平板部FF1的背侧，第二背板112设置于焊盘部FF3朝向平板部FF1的一侧；刚性支撑层12设置于第一背板111和第二背板112之间；其中，背板层11设置为黑色遮光材料，第一背板111与刚性支撑层12直接贴附。
具体的，弯折部FF2弯折后，焊盘部FF3位于平板部FF1的背侧，可以减小显示装置100的边框。
具体的，焊盘部FF3包括焊盘端子15，显示装置100通过焊盘端子15电性连接驱动芯片或/和电路板等结构。
具体的，弯折部FF2弯折后，显示装置100包括层叠设置的焊盘部FF3、第二背板112、刚性支撑层12、第一背板111、平板部FF1。在一些是实施例中，显示装置100还可以包括偏光片13和保护盖板14（cover glass，CG，窗口）。具体的，偏光片13设置于显示面板本体10的显示侧，保护盖板14设置于偏光片13远离显示面板本体10的一侧。
具体的，显示面板本体10或平板部FF1的显示侧是指显示图像或人眼观测的一侧。
具体的，背板层11包括第一背板111和第二背板112，第一背板111设置于平板部FF1的背侧，第二背板112设置于焊盘部FF3朝向平板部FF1的一侧，可以通过将图案化的背板层11贴附在显示面板本体10的背侧实现。
具体的，如图2所示，在弯折部FF2弯折之前，第一背板111设置于平板部FF1的背侧，第二背板112设置于焊盘部FF3的背侧，即第一背板111和第二背板112设置于显示面板本体10的同一侧。
具体的，如图3所示，在弯折部FF2弯折之后，背板层11包括第一背板111和第二背板112，第一背板111设置于平板部FF1的背侧，第二背板112设置于焊盘部FF3朝向平板部FF1的一侧。
具体的，如图3所示，在弯折部FF2弯折之后，刚性支撑层12设置于第一背板111和第二背板112之间。可以通过如图2所示的，在弯折部FF2弯折之前，将刚性支撑层12设置于第一背板111远离平板部FF1的一侧。
具体的，刚性支撑层可以包括不锈钢材料（SUS）。
具体的，背板层11设置为黑色遮光材料，更具的，第一背板111为黑色遮光材料，可以黑色遮光显示面板本体10的背侧的环境光线通过显示面板本体10。
具体的，显示面板本体10或平板部FF1的背侧是指非显示图像的一侧，或者是远离显示侧的一侧。
具体的，如图3所示，第一背板111与刚性支撑层12直接贴附，第一背板111与刚性支撑层12之间不再设置缓冲与遮光层50，因此可以极大的减小显示装置100的厚度，更利于显示装置100的弯折。
具体的，比较图1和图3，通过设置背板层11设置为黑色遮光材料，背板层11可以代替现有技术中的背板层和缓冲遮光层（一般为黑色泡棉），因为背板11自身具有一定的缓冲作用，再设置为黑色遮光材料，那么背板层11同时可以起到缓冲和遮光的作用，从而可以不设置缓冲与遮光层50，可以将背板层和缓冲与遮光层合二为一，省去缓冲与遮光层的使用，可以减小显示装置的厚度，使得显示装置更加轻薄化。
在一些实施例中，黑色遮光材料包括聚酰亚胺和对苯二甲酸乙二醇酯中的至少一种，聚酰亚胺和对苯二甲酸乙二醇酯中掺杂有黑色的材料。
具体的，聚酰亚胺（PI）和对苯二甲酸乙二醇酯（PET）自身为透明材料，在其中掺杂有黑色的材料，例如掺杂黑色的颗粒，可以使得聚酰亚胺（PI）和对苯二甲酸乙二醇酯（PET）也具有黑色遮光作用。
具体的，黑色的材料可以为碳粉。
具体的，在一些实施例中，显示装置100还包括第一胶体层17，第一胶体层17至少设置于弯折部的外侧，可以起到保护弯折部FF2的作用。
在本申请实施例中，通过设置具有黑色遮光功能的背板层，将现有技术中的背板层和缓冲与遮光层合二为一，减小缓冲与遮光层的使用，可以减小显示装置的厚度，使得显示装置更加轻薄化。
实施例二、
本实施例与上述实施例相同或相似，不同之处增加了第二胶体层18，同时去除第二背板112。
请参阅图4、图5、图6、图7、图8、图9，图4为本申请实施例提供的显示装置100的第二种弯折前的示意图；图5为本申请实施例提供的显示装置100的第二种弯折后的示意图；图6为本申请实施例提供的显示装置100的第三种弯折后的示意图；图7为本申请实施例提供的显示装置100的第四种弯折后的示意图；图8为本申请实施例提供的显示装置100的第三种弯折前的示意图；图9为本申请实施例提供的显示装置100的第五种弯折后的示意图。

具体的，显示装置100不包括第二背板112，相比于实施例一，可以进一步减小显示装置100的厚度。
在一些实施例中，刚性支撑层12与焊盘部FF3直接贴附。
具体的，显示装置100不包括第二背板112，刚性支撑层12通过双面胶31直接贴附于焊盘部FF3朝向平板部FF1的一侧，即刚性支撑层12与焊盘部FF3之间不设置其他层结构，此时显示装置100可以具有最小的厚度。
在一些实施例中，显示装置100还包括第一胶体层17和第二胶体层18，第二胶体层18包括第一子胶体件181，第二胶体层18的弹性模量大于第一胶体层17的弹性模量，第二胶体层18设置于显示面板本体10的表面上；第一胶体层17设置于弯折部FF2的外侧，第一背板111包括朝向弯折部FF2的第一边缘201，刚性支撑层12包括朝向弯折部FF2的第二边缘202，第一子胶体件181在显示面板本体10上的正投影覆盖第一边缘201在显示面板本体10上的正投影。
具体的，图4、图5、图6、图7、图8、图9所示，显示装置100不包括第二背板112，可以进一步减小显示装置100的厚度。
具体的，比较图3和图5，显示装置100不部包括第二背板112，显示装置100的厚度进一步减薄，弯折部FF2弯折时，非常容易带动显示面板本体10的弯折部FF2与平板部FF1相交或相邻的部位弯折，设置第二胶体层18用以保护弯折部FF2与平板部FF1相交或相邻的部位，避免此部位弯折或过度弯折，从而防止了此部位的走线和电极发生断裂。
具体的，显示面板本体10上设置第二胶体层18的部位被加固和加强，补偿了去除缓冲与遮光层、第二背板112所带来的走线和电极发生断裂的不利因素，同时极大的减小了显示装置100的厚度。
具体的，第一背板111包括朝向弯折部FF2的第一边缘201，刚性支撑层12包括朝向弯折部FF2的第二边缘202，即第一背板111靠近弯折部FF2的边缘为第一边缘201，刚性支撑层12靠近弯折部FF2的边缘为第二边缘202。
具体的，第二胶体层18的弹性模量大于第一胶体层17的弹性模量，第二胶体层18设置于显示面板本体10的表面上，第一子胶体件181在显示面板本体10上的正投影覆盖第一边缘201或第二边缘202在显示面板本体10上的正投影。第一胶体层17的弹性模量相对较小，可以保护弯折部FF2，同时容易弯折。第二胶体层18的弹性模量相对较大，可以使得第一背板111与显示面板本体10受到外力时不容易剥离，保护显示面板本体10对应第一边缘201的部位的走线和电极不断裂，例如，弯折部FF2弯折时，或者弯折部FF2受到外力挤压时，弯折部FF2容易带动显示面板本体10对应第一边缘201的部位发生变形，而通过第一子胶体件181的设置，加强了此部位显示面板本体10的强度，防止了显示面板本体10在对应第一边缘201的部位发生弯折等变形，从而防止了此部位的走线和电极发生断裂。
具体的，第二胶体层18设置于显示面板本体10的表面上，第二胶体层18设置于显示面板本体10远离背板层11的表面，或第二胶体层18设置于显示面板本体10靠近背板层11的表面，在此不限定。

具体的，由于第一子胶体件181有一部分位于弯折部FF2上，第一子胶体件181与偏光片13的边缘的距离大于0微米，即第一子胶体件181与偏光片13的边缘不接触，可以防止弯折部FF2弯折时通过第一子胶体件181带动偏光片13变形，从而防止显示装置100性能下降，提升显示装置100的可靠性。
具体的，第一子胶体件181与偏光片13的边缘的距离小于或等于200微米，第一子胶体件181与偏光片13的边缘的距离不宜过大，当第一子胶体件181与偏光片13的边缘的距离过大时，会导致偏光片13的边缘与弯折部FF2的距离过大，导致显示装置100在此部位的边框的宽度过大，降低了显示装置100的窄边框性能。
在一些实施例中，显示装置100还包括驱动芯片16，以及设置于焊盘部FF3的远离刚性支撑层12的表面上的焊盘端子15，驱动芯片16电连接焊盘端子15，第二子胶体件182接触焊盘端子15。

具体的，如图8、图9所示，第一子胶体件181或/和第二子胶体件182设置于显示面板本体10靠近第一背板111的表面。
具体的，第一子胶体件181接触第一背板111的侧边缘，第一子胶体件181可以保护显示面板本体10对应第一边缘201的部位的走线和电极不断裂，例如，弯折部FF2弯折时，或者弯折部FF2受到外力挤压时，弯折部FF2容易带动显示面板本体10对应第一边缘201的部位发生变形，而通过第一子胶体件181的设置，阻挡了此部位显示面板本体10的弯折，防止了显示面板本体10在对应第一边缘201的部位发生弯折等变形，从而防止了此部位的走线和电极发生断裂。
具体的，第二子胶体件182接触刚性支撑层12的侧边缘，第二子胶体件182可以保护显示面板本体10对应第二边缘202的部位的走线和电极不断裂，例如，弯折部FF2弯折时，或者弯折部FF2受到外力挤压时，弯折部FF2容易带动显示面板本体10对应第二边缘202的部位发生变形，而通过第二子胶体层182的设置，阻挡了此部位显示面板本体10的弯折，防止了显示面板本体10在对应第二边缘202的部位发生弯折等变形，从而防止了此部位的走线和电极发生断裂。
实施例五、
本实施例与实施例二、实施三、实施四相同或相似，不同之处为：第二胶体层18的设置方式不同，第二胶体层18的弹性模量与第一胶体层17的弹性模量相同。
请参阅图10、图11、图12，图10为本申请实施例提供的显示装置100的第四种弯折前的示意图；图11为本申请实施例提供的显示装置100的第六种弯折后的示意图；图12为本申请实施例提供的显示装置100的第五种弯折前的示意图。
在一些实施例中，显示装置100还包括第一胶体层17和第二胶体层18，第二胶体层18包括第一子胶体件181，第一子胶体件181的厚度大于第一胶体层17的厚度，第二胶体层18的弹性模量等于第一胶体层17的弹性模量，第二胶体层18设置于显示面板本体10的表面上；第一胶体层17设置于弯折部的外侧，第一背板111包括朝向弯折部FF2的第一边缘201，刚性支撑层12包括朝向弯折部FF2的第二边缘202，第一子胶体件181在显示面板本体10上的正投影覆盖第一边缘201或第二边缘202在显示面板本体10上的正投影。
具体的，第二胶体层18的弹性模量与第一胶体层17的弹性模量相同，第二胶体层18设置于显示面板本体10的表面上，通过设置第一子胶体件181的厚度大于第一胶体层17的厚度，即增加第一子胶体件181的厚度，也可以提高对第一边缘201或/和第二边缘202与显示面板本体10接触部位的保护，可以使得第一背板111与显示面板本体10受到外力时不容易剥离，或刚性支撑层12与显示面板本体10受到外力时不容易剥离，保护显示面板本体10这个部位的走线和电极而不断裂。
在一些实施例中，第二胶体层18还包括第二子胶体件182，第二子胶体182件的厚度大于第一胶体层17的厚度；第一子胶体件181在显示面板本体10上的正投影覆盖第一边缘201在显示面板本体10上的正投影，第二子胶体件182在显示面板本体10上的正投影覆盖第二边缘202在显示面板本体10上的正投影。
具体的，同时设置加厚的第一子胶体件181和第二子胶体件182，可以同时保护第一边缘201和第二边缘202对应的部位。
具体的，第二胶体层18的弹性模量等于第一胶体层17的弹性模量，即表示第二胶体层18和第一胶体层17为同一种材料。
进一步的，在一些实施例中，第一子胶体件181和第二子胶体件182为相互连接的一体结构。
具体的，如图10所示，第一胶体层17和第二胶体层18通过同一工艺形成，例如同时涂布或喷涂形成，使得第一子胶体件181、第一胶体层17和第二子胶体件182为依次连接的一体结构，同时形成了第一胶体层17和第二胶体层18，可以简化制作工艺，又可以完成对各个部位的保护。
进一步的，在一些实施例中，第一子胶体件181向第一胶体层17的厚度逐渐减小，第二子胶体件182向第一胶体层17的厚度逐渐减小。
具体的，第一子胶体件181和第二子胶体件182具有较厚的厚度，第一胶体层17具有较小的厚度，第一子胶体件181向第一胶体层17的厚度逐渐减小，第二子胶体件182向第一胶体层17的厚度逐渐减小，在一些情况下可以更好的满足显示面板本体10的性能的需求，例如弯折部FF2的中心的弯折角度最大，需要相对厚度小一些的第一胶体层17，第一子胶体件181和第二子胶体件182对应的部位最容易发生剥离，需要设置相对较大的厚度。
在一些实施例中，显示装置100还包括偏光片13，偏光片13设置于显示面板本体10的平板部FF1的显示侧，第一子胶体件181与偏光片13的边缘的距离大于0微米，且小于或等于200微米。

具体的，第一子胶体件181与偏光片13的边缘的距离小于或等于200微米，第一子胶体件181与偏光片13的边缘的距离不宜过大，当第一子胶体件181与偏光片13的边缘的距离过大时，会导致偏光片13的边缘与弯折部FF2的距离过大，导致显示装置100在此部位的边框的宽度过大，降低了显示装置100的窄边框性能。
在一些实施例中，显示装置100还包括驱动芯片16，以及设置于焊盘部FF3的远离刚性支撑层12的表面上的焊盘端子15，驱动芯片16电连接焊盘端子15，第二子胶体件182接触焊盘端子15。
