在本申请的上述实施例中，通过采用黑色橡胶材料代替现有技术采用的泡棉材料，既能发挥泡棉的缓冲作用，又能改善泡棉不平整表面带来的橘纹等外观问题。
在本申请的上述实施例中，所述硬化层15的材料包括基于聚甲基丙烯酸甲酯的聚合物材料和基于硅的聚合物材料，且所述硬化层15的厚度范围在5um~20um之间。
在本申请的上述实施例中，制备所述硬化层15的过程如下：
首先调制液体作为硬质涂层(Hard coating)浆料。所述硬质涂层浆料是化学聚合物原材料的组合。所述硬质涂层浆料形成所述硬化层15，是由无机和有机混合物合成。举例来说，所述硬质涂层浆料可以由基于聚甲基丙烯酸甲酯(Poly(methylmethacrylate)，PMMA)的聚合物和基于硅的聚合物形成。需要了解的是所述硬质涂层浆料的无机物和有机物可以用其他材料组成。硅聚合物可以包括环氧乙烷、倍半硅氧烷等聚合物。代替PMMA的材料还可以是具有环氧基、丙烯酸酯基、聚氨基甲酸酯丙烯酸酯基等的至少一种官能团的单体或低聚物。首先制备质量浓度为20%～30％的硬质涂层浆料，将其涂覆于所述缓冲层14中远离所述支撑层13的一面，之后在烘箱中对所述缓冲层14上的硬质涂层浆料薄膜进行烘烤，最终得到所述硬化层15。
其中，若所述硬质涂层浆料的质量浓度小于20%，则最终得到的所述硬化层15的硬度过低而难以抵抗橡胶材料在热胀冷缩产生的应力；若所述硬质涂层浆料的质量浓度大于30%，导致所需的溶剂量过少，则最终得到的所述硬化层15难以完全沉积于所述缓冲层14上。
本申请的上述实施例通过在所述缓冲层14表面涂覆一层硬化层15，既能在涂覆过程中流平所述缓冲层14采用橡胶材料时的不平整的表面，改善所述缓冲层14的平坦度，硬化后又能抵抗橡胶材料在热胀冷缩产生的应力，避免直接作用于显示面板的背板，致显示面板受力过大。
在本实施例中，所述硬化层15的厚度范围在3um~20um之间，具体为10um。
在本申请的上述实施例中，本申请实施例提供的支撑复合板10还包括设置于所述硬化层15上的粘合胶层，所述粘合层用于将所述硬化层15与显示面板的背板粘合起来。进一步地，所述粘合层为压敏胶(Pressure

或者，先将制备所述缓冲层14的橡胶材料压制成凸型结构，再在所述缓冲层14的凸块的两端贴合具有开口的所述支撑层13。
所述步骤S10中，所述开口由所述支撑层13在弯折区域图案化形成。
可选的，在本申请的一些实施例中，所述支撑复合板10还包括第一弯折区和第二弯折区，所述支撑层13内设置有第一开口和第二开口，所述第一弯折区与所述第一开口对应，所述第二弯折区与所述第二开口对应，所述第一开口的截面形状与所述第二开口的截面形状不相同。

可选的，在本申请的一些实施例中，所述支撑层13包括向所述开口延伸的至少一个凸起，所述凸起设置于所述弯折区内，所述凸起由所述支撑层13通过图案化工艺制备而成。
Step2（步骤2）：首先制备浓度为20～30％的硬质涂层浆料，将其涂覆于所述缓冲层14中远离所述支撑层13的一面，之后在烘箱中对所述缓冲层14上的硬质涂层浆料薄膜进行烘烤，最终得到所述硬化层15。其中，所述硬化层15的材料包括基于聚甲基丙烯酸甲酯的聚合物材料和基于硅的聚合物材料，且所述硬化层15的厚度范围在5um~20um之间。
Step3（步骤3）：在所述硬化层15表面涂布PSA或者OCA形成粘合层16。
