本发明实施例提供一种基板、显示面板及其制作方法和显示装置。以下将分别进行详细说明。
参阅图1，本发明提供一种基板。所述基板包括一衬底110和设置在所述衬底110的一表面上的至少一多孔金属层101。所述多孔金属层101的材料为铜、铝、铁、镍、锌铜合金、镍铜合金、镍铜合金、镍铬钨合金及镍铁合金中的一种或多种的组合。所述多孔金属层101是通过液相法、固相法、金属沉积法中的一种方式而制成。所述多孔金属层101包括多个具有方向性或随机性的孔。
由于所述多孔金属层101采用诸如泡沫铜，泡沫铝合金、镍铬钨合金及镍铁合金等材料，且这些材料混合之后所形成的金属层其内部分布着大量的有方向性或随机的空洞，因此能够起到很好的保护和缓冲作用。且，所形成的多孔金属层101吸能能力可达490KJ/m 3～3430KJ/m 3，能对显示面板起到良好的保护作用。所形成的多孔金属层101还具有很好的电磁波吸收特性，可以起到电磁保护的作用。所形成的多孔金属层101在作为散热材料时，散热能力能达到30～40W/(m∙K)。另外，所形成的多孔金属层101还具有比重小，能量吸收强、制振性能好，比表面积大等特性。有鉴于所述多孔金属层101具有优异的性能，因此，可以将现有分别起着保护、缓冲、散热等的多个功能层进行合并，以达到一层材料实现多层功能的效果，因此，可以将该多孔金属层101应用于显示面板上，从而能够有效降低组件厚度，并且简化原有显示面板的工艺流程。
根据本发明的另一方面，本发明提供一种显示面板，所述显示面板包括上述基板、设置在所述基板上的像素阵列。所述显示面板可以为OLED面板或LCD面板。当所述显示面板为OLED面板时，所述像素阵列包括层叠设置的薄膜晶体管层和电致发光层。当所述显示面板为LCD面板时，所述像素阵列包括层叠设置的薄膜晶体管层和彩膜层以及设置在所述薄膜晶体管层和彩膜之间的液晶。
以下将以本发明所述显示面板为OLED面板为例进行描述，并且与现有的OLED面板进行比较。
参阅图2，现有的OLED面板包括：一柔性基板205、薄膜晶体管层206（由低温多晶硅工艺制备而成）、电致发光层207、触摸屏208、偏光片209和盖板210。并且在OLED面板的背部设置聚对苯二甲酸乙二酯（PET）层204、泡沫层203、铜箔层202以及石墨层201，以起到保护、缓冲、散热等作用，但是这样就会增加了OLED面板的厚度，阻碍了更轻薄的显示器件的发展。
参阅图3，本发明提供了一种OLED面板300。
在一实施例中，所述OLED面板300包括：包括上述多孔金属层301和衬底（图中未示）的基板和设置在所述基板上的像素阵列320。其中，所述像素阵列320包括层叠设置的薄膜晶体管层322和电致发光层323。
在本实施例中，所述基板进一步包括一设置在所述衬底上的PI膜层（图中未示），所述PI膜层是由聚酰亚胺材料制成。由于聚酰亚胺材料具有温度广、耐化学腐蚀、高强度等优点，因此所述PI膜层和所述衬底所形成的柔性基板310具有良好的柔韧性。当然，在本发明的其他部分实施中，所述柔性基板310也可以采用聚醚酰亚胺（PET）、聚苯硫醚（PPS）、聚芳酯（PAR）等一种或几种材料组合制成。
在所述柔性基板310上设置有像素阵列320。所述像素阵列320包括依次层叠设置有薄膜晶体管层322和电致发光层323。所述薄膜晶体管层322通过采用低温多晶硅（LTPS）工艺而制成。当然，在其他部分实施例中，所述薄膜晶体管层322也可以通过氧化铟镓锌（IGZO）工艺制成。
可选的，所述像素阵列320还可以包括薄膜封装层（图未示），所述薄膜封装层设置在所述电致发光层323上。所述薄膜封装层用于阻挡水气侵蚀。
另外，所述OLED面板300还包括一触摸模块330，所述触摸模块330包括触摸层331和盖板玻璃333。所述触摸层331用于实现触控功能。优选的，所述触摸层331采用电子墨水膜。所述盖板玻璃333用于保护所述触摸模块330和所述像素阵列320。
另外，所述OLED面板300还包括偏光片332，所述偏光片332设置在所述触摸模块330中的触摸层331和盖板玻璃333之间。所述偏光片332用于减少外部入射光线造成的反射影响。在其他部分实施例中，所述偏光片332也可以设置在电致发光层323上。或者，所述偏光片332与所述触摸层331制作为一层。
所述柔性基板310的背部为多孔金属层301。所述多孔金属层301采用多孔金属材料制成。
所述多孔金属材料可以为如泡沫铜，泡沫铝合金、镍铬钨合金及镍铁合金等材料，这些材料混合之后所形成的金属层内部弥散分布着大量的有方向性或随机的空洞，因此能够起到很好的保护和缓冲作用。且，所形成的多孔金属层吸能能力可达490KJ/m 3～3430KJ/m 3，能对显示面板起到良好的保护作用。所形成的多孔金属层还具有很好的电磁波吸收特性，可以起到电磁保护的作用。所形成的多孔金属层在作为散热材料时，散热能力能达到30～40W/(m∙K)。而现有OLED面板中所使用石墨层、铜箔层的导热性能虽然达到了100 W/(m∙K)、370 W/(m∙K)，但是因直接与热源OLED面板接触的PET材料的导热性能仅为0.2 W/(m∙K)，且因为接触热阻的存在，导热性能实际上不如本发明仅采用一层多孔金属层的导热性能。
另外，所形成的多孔金属层还具有比重小，能量吸收强、制振性能好，比表面积大等特性。有鉴于所述多孔金属层具有优异的性能，因此，可以将现有分别起着保护、缓冲、散热等的多个功能层进行合并，以达到一层材料实现多层功能的效果，从而能够将该多孔金属层应用于不同的显示面板上，以有效降低显示面板的组件厚度。
在本实施例中，所述多孔金属层310可以通过液相法、固相法、金属沉积法中的任意一种方式而制成。
参阅图4，本发明还提供一种显示装置400，所述显示装置400包括上述的OLED面板300或者LCD面板（图未示）。在此不再详述OLED面板的具体结构。另外，由于LCD面板的基本结构为本领域技术人员所熟知的，因此，在此也不再赘述。另外，所述显示装置可以为但不仅限于电子书、智能手机、数字电视、平板电脑、掌上电脑、笔记本电脑、移动互联网设备或穿戴式设备等。
参阅图5，本发明还提供一种基板的制作方法，其包括以下步骤：
步骤S510：提供一衬底；
步骤S520：在所述衬底的一表面上形成至少一多孔金属层；
在步骤S520中，可以通过液相法、固相法、金属沉积法中的一种方式来制成多孔金属层。
另外，在步骤S520中，所述多孔金属层的材料为铜、铝、铁、镍、锌铜合金、镍铜合金、镍铜合金、镍铬钨合金及镍铁合金中的一种或多种的组合。
本发明的优点在于，本发明所述显示面板通过采用新兴的多孔金属材料使其能同时承担保护、缓冲和散热等职责，以达到了简化显示器件结构、降低显示面板整个组件厚度，使得显示面板更加简单、厚度更加轻薄。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
