例如，功能部件可以为触控屏，触控屏是一种简单方便的输入设备，可以包括基板以及形成于基板上的触控结构，通过触控结构的电容变化来感应触控位置。
例如，图2B为图2A所示的功能部件的结构示意图。如图2B所示，功能部件160可以包括三层玻璃，即，保护玻璃163、设置有屏蔽件1620的屏蔽玻璃162和设置有加热件1610的加热玻璃161。加热玻璃161位于屏蔽玻璃162靠近显示面板的一侧，保护玻璃163位于屏蔽玻璃162远离加热玻璃161的一侧。在显示装置应用于适合多人使用的公共显示器(例如该公共显示器适用于车、船或商场等环境)时，在显示面板远离背光模组的最外侧可以设置保护玻璃，该保护玻璃表面易于清洗；液晶显示装置的液晶屏常在低温条件下启动，通过设置在液晶屏表面的加热玻璃给液晶屏加热，可以提高液晶屏的启动反应速度；而设置在加热玻璃与保护玻璃之间的屏蔽玻璃可以对显示面板起到电子屏蔽效果。本实施例不限于功能部件包括上述三层玻璃，还可以包括上述三层玻璃中的任一个或任意两个。
如图2A所示，支撑框121被配置为固定功能部件160和背光模组140，且功能部件160与显示面板150粘结以固定显示面板150。在显示装置设计为大尺寸显示装置时，本实施例中的背光模组被外壳固定，而与显示装置外壳粘结的功能部件仅与显示面板贴合，该功能部件可以仅承载显示面板的重量，而不再需要承载背光模组的重量，从而可以减小背光模组的负重，以降低功能部件损坏的几率。
例如，如图2A所示，支撑框121包括支撑部1211，支撑部1211位于功能部件160面向显示面板150的一侧，且与功能部件160粘结以固定功能部件160。本实施例不限于此，功能部件还可以通过其他方式固定在支撑部上。
例如，如图2A所示，在平行于显示面板150的主平面的方向，显示面板150的尺寸小于功能部件160，功能部件160的除了被支撑部1211支撑的部分 外的表面与显示面板150全贴合粘结以固定显示面板150。本实施例中的显示面板与功能部件粘结为一体，在功能部件的位置固定的同时，显示面板的位置就固定了。
例如，如图2A所示，支撑部1211在功能部件160上的正投影与显示面板150在功能部件160上的正投影没有交叠，即，支撑部1211仅通过固定功能部件160而使得显示面板150也得到了固定。
例如，如图2A所示，在平行于显示面板150的主平面方向，功能部件160与外壳100之间可以具有较小的缝隙以使功能部件160更容易放置在支撑部1211上以实现位置的固定。
例如，如图2A所示，在平行于显示面板150的主平面的平面内，支撑部1211位于功能部件160的四周边缘，以固定功能部件160的四周，从而固定功能部件。
本示例中的显示面板通过与功能部件的全贴合粘结而固定了显示面板的位置，从而节省了模组部分的前框和中框，简化了结构。
例如，图3A示出了图2A所示的示例中的背光模组的局部结构。如图3A所示，背光模组140包括：光源101，位于显示面板150远离功能部件160的一侧，且支撑框121的内侧与光源101导热连接以使外壳100作为光源101的散热结构。本公开实施例提供的显示装置无需单独设置位于外壳内的用于为光源散热的散热结构，而是直接将外壳作为光源的散热结构，既可以节省外壳内的空间，还可以使光源在工作时产生的热量能够传导到外壳上，并通过外壳及时的散发出去，从而提升显示装置的散热效率，提高产品高温工作的可靠性。此外，采用本公开实施例的设置方式还可以使高亮度需求的显示装置做到充分的散热。由此，本公开实施例提供的显示装置的外壳集成了一般模组机中的中框以及散热板的功能，进一步简化了结构。
上述的导热连接指光源的至少部分表面与外壳的至少部分表面直接接触(接触面可以存在微观间隙)或者通过导热材料连接。
例如，作为光源101的散热结构的外壳100采用导热材料制成，导热材料即为导热系数较高的材料。
例如，外壳100的材料可以包括铜、铝或者铜和铝结合的材料等。
本实施例提供的显示装置的外壳的材料可以采用铝，此时，外壳的强度较高。由此，该显示装置也满足对外壳强度要求较高的产品的需求。
例如，图3B为图3A所示的外壳沿AA线所截的平面结构示意图。图3B示意性的示出了图3A所示的显示装置沿AA线所截的平面结构。如图3B所示，支撑框121围绕开口，支撑框121的内侧指在XZ平面内，支撑框121围绕的区域1201，支撑框121的外侧指在XZ平面内，支撑框121围绕的区域以外的区域1202。
例如，如图3A所示，支撑部1211相对于光源101向支撑框121的内侧延伸，即支撑部1211的内侧端相对于光源101更靠近支撑框121围绕的内侧区域的中心。例如，光源101在功能部件160上的正投影位于支撑部1211在功能部件160上的正投影内。
例如，光源101包括发光二极管灯条1010与印刷电路板(PCB板)1011，发光二极管灯条1010与印刷电路板1011电连接。例如，该印刷电路板1011包括金属板，发光二极管灯条1010设置在该金属板上。印刷电路板1011通过导热胶与支撑框121粘结，且粘结在支撑框121的内侧。由此，光源与支撑框通过导热材料连接以实现光源与支撑框的导热连接。本实施例中的光源虽然位于外壳内，但是光源与外壳包括的支撑框通过导热胶粘结，从而实现光源与外壳的导热连接。
例如，光源可以通过导热双面胶与支撑框粘结，导热双面胶是由压克力聚合物填充导热陶瓷粉末，与有机硅胶黏剂复合而成。具有高导热和绝缘的特性，并具有柔软性、压缩性、服帖性和强粘性。导热双面胶适应温度范围大，能紧密牢固地贴合光源和支撑框，将从而将热量快速传导出去。
外壳作为光源的散热结构可以起到为发光二极管灯条以及印刷电路板散热的作用，即，发光二极管灯条产生的热量通过印刷电路板传导到外壳，以实现热量的散发。
例如，光源101可以包括至少一个发光二极管灯条1010，本实施例对此不作限制。
例如，印刷电路板1011与发光二极管灯条1010电连接，印刷电路板1011为发光二极管灯条1010提供电源以及对灯光强度进行控制，印刷电路板1011实现了为显示装置提供可调节的匀强亮光的作用。
例如，如图3A所示，背光模组140还包括导光板141以及取光结构143，光源101位于导光板141侧面的入光侧，且导光板141的出光侧面向显示面板150。光源101发出的光进入导光板141后在导光板141中全反射传播，然后 被位于导光板141的出光面的取光结构143均匀的取出。
例如，取光结构143可以包括设置在导光板141表面的网点膜。本实施例不限于网点膜位于导光板面向显示面板的一侧，网点膜还可以位于导光板远离显示面板的一侧。例如，网点膜的材料可以与导光板141材料相同，网点膜中分布有凹凸结构的网点。
例如，网点膜还可以替换为特定的一维光栅结构或者二维光栅结构等，本实施例对此不作限制。取光结构主要针对具体的光源和导光板的出光情况进行设计，以实现背光光强的均匀分布。
例如，取光结构143还包括设置在网点膜远离导光板141的一侧的扩散膜，穿过扩散膜的光线会被其中的散射颗粒散射，使观察者感知光是由扩散膜表面直接提供的亮度分布。
例如，取光结构143还可以包括设置在扩散膜远离导光板141的一侧的棱镜膜，棱镜膜被配置为将大角度的光向小角度集中，增加正视角的观看亮度。
例如，取光结构143与显示面板150之间可以设置有一定间距以防止取光结构143对显示面板150面向导光板141的表面造成划伤。
例如，如图3A所示，背光模组140还包括位于导光板141远离显示面板150的一侧的背板142，背板142被配置为承载导光板141以及取光结构143等部件，且背板142与支撑框121导热连接以使支撑框121可以固定背光模组140。
例如，导光板141可以通过设置于其面向背板142一侧(例如四周边缘)的双面胶与背板142粘结。
例如，导光板141与背板142之间还可以包括反射片(图中没有示出)，反射片的设置有利于将光源发出的光线反射到显示面板中，以增加光的利用率。
例如，如图3A所示，背板142与支撑框121连接以使导光板141位于光源101的出光侧。
例如，本实施例的一示例中的光源101还可以与背板142导热连接，背板142选用导热材料制成，从而外壳以及背板均作为光源的散热结构，可以更好的起到为发光二极管灯条以及印刷电路板散热的作用。
例如，背板142可以通过导热材料与支撑框121连接，例如，背板142也可以通过导热双面胶与支撑框121粘结。本实施例不限于此，例如，背板与支 撑框之间也可以通过弹性卡接或螺钉连接的方式进行连接。
例如，在背板142与支撑框121导热连接的情况下，导光板141也可以与外壳100粘结，以更好的固定背光模组140。
例如，如图3A所示，前壳120还包括前壳侧壁122以及与前壳侧壁122连接的前框123，前壳侧壁122位于前框123的外侧，前框123与支撑框121连接，且支撑框121位于前框123的内侧。前壳侧壁122位于前框123远离开口111的一侧，支撑框121位于前框123靠近开口111的一侧。
例如，如图3A所示，前框123垂直于Y方向，前壳侧壁122垂直于X方向，X方向垂直于Y方向。
例如，前框123可以通过多种表面处理以形成显示装置的外观面，无需再额外增加装饰框，减少部件构成，节省成本。
例如，如图3A所示，前壳侧壁122、前框123以及支撑框121一体成型。外壳包括的前壳为一体化的结构，因此，与支撑框导热连接的光源的热量可以直接传导到前框以及前壳侧壁，并散发出去。本实施例中的外壳包括的前壳的散热面积远大于传统的为光源散热的散热结构的面积，由此，本实施例提供的外壳可以具有更好的散热效果，提升产品的散热效率。
例如，如图3A所示，外壳100还包括后壳130，后壳130与前壳120连接以形成容纳腔110。
例如，如图3A所示，功能部件160的远离显示面板150的表面与前框123的远离后壳130的表面齐平。
例如，如图3A所示，后壳130包括垂直于Y方向的底板以及与底板连接的后壳侧壁，后壳130与前壳侧壁122连接，即后壳侧壁与前壳侧壁122连接以构成外壳100的侧壁。
例如，后壳130与前壳120通过螺钉固定连接，此时，前壳与后壳的连接也为导热连接，在光源将其热量传导给前壳后，会有一部分热量从前壳传导到后壳，并从后壳散发出去。本实施例中的外壳包括的前壳和后壳的散热面积远大于传统的为光源散热的散热结构的面积，由此，本实施例提供的外壳可以具有更好的散热效果，提升产品的散热效率。
例如，图4为本公开一实施例的另一示例提供的显示装置的局部结构示意图。如图4所示，显示面板150包括显示区151以及围绕显示区151的周边区152。支撑框121还包括遮光部1212，遮光部1212位于导光板141与显示面板 150之间，且遮光部1212在功能部件160上的正投影与显示面板150的周边区152在功能部件160上的正投影有交叠。遮光部的设置可以使背光模组发出的光仅能经过显示面板后出射，从而防止漏光现象发生。
例如，如图4所示，遮光部1212相对于光源101向支撑框121的内侧突出用于遮光。
例如，如图4所示，遮光部1212相对于支撑部1211向支撑框121的内侧突出，遮光部1212的内侧端比支撑部1211的内侧端更靠近支撑框121围绕的内侧区域的中心，即遮光部1212和支撑部1211构成了台阶结构。
例如，如图4所示，遮光部1212向支撑框121内侧延伸的尺寸大于支撑部1211向支撑框121内侧延伸的尺寸。
例如，遮光部1212位于显示面板150的四周，即，在垂直于Y方向的平面内，遮光部1212遮住显示面板150的四周，以防止漏光。例如，遮光部1212在功能部件上的正投影与显示面板150的显示区域在功能部件上的正投影没有交叠。
例如，如图4所示，本示例中的支撑框121可以为一体结构，也可以为分体结构。例如，遮光部1212和支撑部1211可以做成一个整体，还可以做成相互连接的两部分。支撑框作为一个整体可以保证结构上的强度。
例如，光源101在功能部件上的正投影位于遮光部1212在功能部件上的正投影内。例如，导光板141在功能部件160上的正投影与遮光部1212在功能部件160上的正投影有交叠。由此，在光源的入光侧的光强不均匀时，遮光部可以遮挡这部分不均匀的光。
例如，本示例中，支撑框121可以与显示面板150粘结以固定显示面板150，即，显示面板150与遮光部1212接触，此时遮光部1212也可以起到固定显示面板150的作用。在本示例中，显示面板还可以与功能部件粘结，从而，功能部件与遮光部共同起到固定显示面板的作用；本示例不限于此，还可以是显示面板仅与支撑框的遮光部粘结，而与功能部件没有粘结，从而，支撑框起到了固定显示面板的作用。
例如，如图4所示，显示装置还包括位于背光模组140远离显示面板150的一侧的驱动板170。例如，驱动板170可以通过导线与显示面板150电连接，以实现驱动板170对显示面板150的驱动。
例如，如图4所示，在支撑框121与显示面板150接触的位置可以设置过 孔，导线可以穿过过孔以实现电连接显示面板150和驱动板170。
例如，图4所示的截面中，沿X方向，位于显示面板150两侧的支撑框中的一侧设置有凹槽102，该凹槽102与显示面板150相对，可以设置用于穿过导线的过孔，本实施例不限于此。沿X方向，位于显示面板150两侧的支撑框的结构(即位于显示面板150两侧的支撑框的截面形状)也可以设置的相同，过孔可以设置在其他位置，只要保证显示面板150与驱动板170电连接即可。
例如，本实施例提供的显示装置可以为液晶显示装置，该显示装置也可以为包括液晶显示装置的电视、数码相机、手机、手表、平板电脑、笔记本电脑、导航仪等任何具有显示功能的产品或者部件，本实施例不限于此。
本公开另一实施例提供一种结构框架，该结构框架包括图4所示的显示装置外壳。本实施例仅以图4所示的显示装置包括的外壳为例进行描述，但不限于此，还可以是图2A所述的显示装置包括的外壳。
图5为本实施例提供的结构框架的剖面结构示意图。如图5所示，该结构框架包括外壳100。外壳100采用导热材料制成，导热材料即为导热系数较高的材料。
例如，外壳100的材料可以包括铜、铝或者铜和铝结合的材料等。
例如，如图5所示，外壳100包括容纳腔110，该容纳腔110为外壳100包裹的空间，且容纳腔110包括开口111。
例如，如图5所示，外壳100包括位于容纳腔110的开口111侧的前壳120，前壳120围绕着开口111。前壳120包括向容纳腔110内延伸的支撑框121。
例如，如图5所示，前壳120还包括前壳侧壁122以及与前壳侧壁122连接的前框123，前壳侧壁122位于前框123的外侧，前框123与支撑框121连接，且支撑框121位于前框123的内侧。前壳侧壁122位于前框123远离开口111的一侧，支撑框121位于前框123靠近开口111的一侧。
例如，如图5所示，前框123垂直于Y方向，前壳侧壁122垂直于X方向，X方向垂直于Y方向。
例如，如图5所示，前壳侧壁122、前框123以及支撑框121一体成型。
例如，如图5所示，外壳100还包括后壳130，后壳130与前壳120连接以形成容纳腔110。
例如，如图5所示，后壳130包括垂直于Y方向的底板以及与底板连接的后壳侧壁，后壳130与前壳侧壁122连接，即后壳侧壁与前壳侧壁122连接以 构成外壳100的侧壁。
例如，后壳130与前壳120通过螺钉固定连接。
例如，如图5所示，支撑框121包括支撑部1211和遮光部1212，遮光部1212位于支撑部1211面向开口的一侧，且遮光部1212相对于支撑部1211向支撑框121的内侧突出，即遮光部1212的内侧端相对于支撑部1211的内侧端更靠近支撑框121围绕的内侧区域的中心。
例如，如图5所示，支撑部1211和遮光部1212构成了台阶结构。
例如，如图5所示，支撑框121可以为一体结构，也可以为分体结构。例如，支撑部1211和遮光部1212可以做成一个整体，还可以做成相互连接的两部分。支撑框作为一个整体可以保证结构上的强度。
本实施例提供的结构框架在用于显示装置的外壳时，位于显示装置内的光源与显示装置的外壳导热连接，可以使光源在工作时产生的热量能够传导到外壳上，并通过外壳及时的散发出去，从而提升显示装置的散热效率，提高产品高温工作的可靠性。此外，该结构框架的设计方式可以节省一般模组部分的前框和中框的设计，从而简化了结构。
