显示屏发热后，热量集中在一个区域无法快速散热，使得温度急剧升高，对终端的元器件造成损耗，同时还会出现烫手、烫耳朵等问题，影响了用户的使用体验。可见，如何有效地对显示屏散热是目前亟需解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例所提供的终端，包括智能手机、平板电脑、智能可穿戴设备、数字音视频播放器、电子阅读器、手持游戏机和车载电子设备等电子设备。本申请实施例中，所述终端配置有显示屏，所述显示屏可以是发光二极管屏，如LED屏、OLED屏等，这里不作具体限定。
图1是现有技术中的一种显示屏的分解示意图，如图所示显示屏至少包括发光二极管屏和显示屏支架。发光二极管屏设置于显示屏支架的一面，需要指出的是，发光二极管发光过程本身就是发热的过程。显示屏支架主要起对发光二极管屏的支撑、固定和保护作用，一般的，显示屏支架的本体为五金材料，如铝合金等。
图2是本申请实施例提供的一种显示屏支架的结构示意图。如图所示本申 请实施例中的显示屏支架至少可以包括本体110、驱动件120和吸热储热件130，本体110呈板状结构，其中：
本体110的一面用于设置图1所描述的发光二极管屏。一般的，显示屏支架的本体为五金材料，如铝合金等。
驱动件120设置于本体110，用于驱动发光二极管屏进行发光显示。具体的，驱动件120与发光二极管屏电连接，当驱动件120向发光二极管屏输出相应的驱动电压和驱动电流时，发光二极管屏发光显示。另外，驱动件120设置在本体110上的具体位置，本实施例不作限定，可选的，如图2所示，驱动件120设置于本体110的顶端。
吸热储热件130设置于本体110，吸热储热件130包括具有吸热和储热功能的材料属性的吸热储热材料131a，用于吸收并存储驱动件和发光二极管屏散发的热量。可选的，吸热储热件130设置于本体110的背离发光二极管屏的另一面上。进一步可选的，吸热储热件130与发光二极管屏隔着本体110相对设置，以快速地吸收并存储发光二极管屏传递至本体110的热量。
进一步的，驱动件120包括驱动电路模块121，吸热储热件130与驱动电路模块121连接。应理解的，驱动电路模块121包括开关管、驱动芯片、稳压管以及稳流管等高发热元器件，是驱动件120的主要发热源。可见，吸热储热件130与驱动电路模块121连接，可以快速地吸收并存储驱动电路模块121散发的热量。
可选的，驱动件120还包括控制芯片122，吸热储热件130与控制芯片122的引脚连接。应理解的，控制芯片122是驱动件120的次要发热源。同理，吸热储热件130与控制芯片122的引脚连接，可以快速地吸收并存储控制芯片122散发的热量。
在本实施例中，吸热储热材料131a可以为一种相变材料，其能够随着温度变化而改变物理性质并能吸收大量的热量，随着吸收的热量的增加，吸热储热材料131a从一种相逐渐转化为另一种相，在吸收充足的热量后会稳定维持另一种相并不再吸热，而当本体110没有热源产生或者热量较低时，吸热储热材料131a进行散热并逐渐随着热量的减少由另一种相逐渐恢复为原来的相。其中，吸热储热材料131a可以随着温度的变化从固相向液相或者液相向固相 转变，或固相向气相或者液相向固相转变，或者液相向气相或者气相向液相转变。
应理解的，吸热储热件130设置于本体110的外表面上，驱动件120与发光二极管屏散发的绝大部分热量传递至本体110的一个集中区域。当该集中区域的热量达到一定温度时，吸热储热件130中的吸热储热材料131a吸收并存储该集中区域的热量。当该集中区域的温度降下来后(如停止工作之后不再发热，使得温度降低)，吸热储热件130中的吸热储热材料131a将储存的热量散发到空气中。
可选的，吸热储热材料131a优选为包括质量比为1∶1至1∶9的二氧化硅和聚乙二醇。发明人通过大量的实验得出，将二氧化硅和聚乙二醇以质量比为1∶1至1∶9混合能够制得的有机-复合相变材料具有适宜的相变温度，能够及时吸收驱动件120和发光二极管屏的热量。具体的，吸热储热材料131a混合制得的相变温度为40度，即在吸收驱动件120和发光二极管屏产生的热量达到40度后，吸热储热材料131a进行相变吸热，将吸收驱动件120和发光二极管屏的热量带走，以对其进行降温。当然，在其它实施例中，吸热储热材料131a还可以为无机相变材料，或者复合相变材料等。
进一步的，吸热储热材料131a由若干以二氧化硅为囊壁、以聚乙二醇为囊芯的微囊构成。该微囊结构的吸热储热材料131a能够较佳地进行吸热储热，进而达到较佳的散热性能。具体的，将聚乙二醇加入到一定浓度的硅溶胶中，待全部溶解后，滴加CaCl2促凝剂溶液，在强力搅拌下，使得聚乙二醇在硅溶胶中发生溶胶-凝胶反应，静置后形成三维网络结构凝胶；将凝胶在80℃烘箱中鼓风干燥24至48h，冷却至室温，即能够得到以有机硅氧化合物在碱性条件下产生的大量以二氧化硅凝胶为囊壁、以乳化后的聚乙二醇为囊芯的微囊。即在每个微囊中，二氧化硅作为囊壁包裹住作为囊芯的聚乙二醇，使得聚乙二醇在从固相-液相的过程中不会泄漏，能够很好的被二氧化硅包裹住。该形成微胶囊结构的吸热储热材料在周围温度达到40度后，开始吸收热量，并且囊芯本身随着热量的逐渐增加逐渐从固相-液相，当囊芯都转化为液相后，吸热储热材料131a吸收的热量已经饱和，其停止吸收热量，而在周围温度逐渐降低至预设温度后，囊芯将吸收的热量散发出来，传递到空气中，并且囊芯 会随着其身热量的逐渐减少而逐渐从液相转换为固相，通过上述固相至液相的循环转换，从而对驱动件120和发光二极管屏进行降温。当然，在其它实施例中，吸热储热材料131a还可以为其它结构，使得吸热储热材料131a能够通过从固相至气相的循环转换来降温。
作为第一种的实施例，请参阅图3，如图所示的吸热储热件130还包括钛酸酯偶联剂131b和胶层132。具体的，如图4所示，将吸热储热材料131a和钛酸酯偶联剂131b混合制成片状材料131，胶层132层叠贴覆于片状材料131上，片状材料131通过胶层132粘接于本体110上。需要指出的是，通过将吸热储热材料131a与钛酸酯偶联剂131b混合制成片状材料131，再通过胶层132层叠连接于片状材料131上形成吸热储热件130，使得吸热储热件可塑性更强，更容易实现与其它部件进行结合。
具体实现过程中，可以将吸热储热材料131a捣碎并强力搅拌得到粉末，由于粉体的直径远远大于每个微囊的直径，因此不会破坏吸热储热材料131a中的微囊结构，即不会影响吸热储热材料131a的吸热储热功能，在粉末状的吸热储热材料131a添加钛酸酯偶联剂131b疏水改性得到无机拟有机复合定形相变材料，再将该无机拟有机复合定形相变材料经压片机压片制得薄片状即片状材料131，片状材料131再层叠连接上胶层132形成吸热储热件130。可选的，胶层132可以为背胶、双面胶或离型膜等。吸热储热件130可以根据与其它部件的结合处的形状裁剪成一定形状，使得更容易结合。
请参阅图3，如图所示的吸热储热件130还包括保护膜133，保护膜133设置于吸热储热件130表面，且保护膜130位于远离本体110的一侧。可选的，保护膜133为聚对苯二甲酸乙二醇酯(PET)，其层叠连接于片状材料131上，且与胶层132相背，保护膜133能够进一步对片状材料131进行定型和具有防尘的作用。当然，在其它实施例中，保护膜133的材质还可以为其它，例如：硅胶。
作为第二种实施例，请参阅图5，如图所示的吸热储热件130还包括稀释溶剂131c和粘结溶液131d，吸热储热材料131a、稀释溶剂131c和粘结溶液131d混合并涂布于本体110上。具体的，如图6所示，将稀释溶剂131c、粘 结溶液131d与吸热储热材料131a混合形成吸热储热件130，使得吸热储热件130直接具有附着力，无需再另外增加胶层即可涂布于本体110上，从而提高便利。
具体实现过程中，将吸热储热材料131a捣碎并强力搅拌得到粉末，由于粉体的直径远远大于每个微囊的直径，因此不会破坏吸热储热材料中的微囊结构，即不会影响吸热储热材料的吸热储热功能，在粉末状的吸热储热材料131a添加进稀释溶剂131c及添加特殊粘结溶液131d(比如：甲醇二甲苯、丙烯酸树脂等)混合，使得吸热储热件130具有附着力，将吸热储热件130直接采用涂布的形式堆积成一定厚度附在本体110上，从而实现吸热储热的功能。
请参阅图5，如图所示的吸热储热件130还包括保护膜133，保护膜133设置于吸热储热件130表面，且保护膜130位于远离本体110的一侧。可选的，保护膜133为聚对苯二甲酸乙二醇酯(PET)，保护膜133能够进一步定型和具有防尘的作用。当然，在其它实施例中，保护膜133的材质还可以为其它，例如：硅胶。
作为第三种实施例，请参阅图7，如图所示的吸热储热件130还包括基底134和胶层132，吸热储热材料131a涂布于基底134上，胶层132层叠连接于基底134上，且胶层132粘接于本体110上。具体的，如图8所示，直接将吸热储热材料131a涂布于基底134上成型，再在基底134上设置胶层132以粘贴于本体110上，无需压片机进行压片，制作较为简单。
具体实现过程中，基底134为聚对苯二甲酸乙二醇酯(PET)，将吸热储热材料131a捣碎并强力搅拌得到粉末，由于粉体的直径远远大于微囊的直径，因此不会破坏吸热储热材料131a中的微囊结构，即不会影响吸热储热材料131a的吸热储热功能，将粉末状的吸热储热材料131a直接涂布于基底134上成型，将具有吸热储热材料131a的基底134通过胶层132粘接于本体110上，实现吸热储热件130的吸热储热功能。可以理解的，胶层可以为背胶、双面胶或者其它等。
请参阅图7，如图所示的吸热储热件130还包括保护膜133，保护膜133设置于吸热储热件130表面，且保护膜130位于远离本体110的一侧。可选的，保护膜133为聚对苯二甲酸乙二醇酯(PET)，保护膜133能够进一步定型和 具有防尘的作用。当然，在其它实施例中，保护膜133的材质还可以为其它，例如：硅胶。
