如图2a和图3所示，本公开一个实施例的显示装置，包括：边框1和平面背壳2，其中，边框1包括边框本体101以及从边框本体101内壁延伸出的第一凸起102；平面背壳2固定于边框本体101的内侧以及第一凸起102远离出光面3的一侧。
其中，边框1可以采用金属边框，如铝型材边框。平面背壳2可以采用钢化玻璃背板或者不锈钢背板。如图2a所示，在一个实施例中，边框1包括天侧边部1a、地侧支撑架部1b、左侧边部1c和右侧边部1d，并且，天侧边部1a与左侧边部1c和右侧边部1d可拆卸连接，例如通过螺钉连接，地侧支撑架部1b与左侧边部1c和右侧边部1d可拆卸连接，例如通过螺钉连接。如此设计，便于金属边框的制作，且能够降低制作成本。
请继续参照图2a和图3所示，为实现基本的显示功能，除边框1和平面背壳2外，显示装置还包括了灯组15、反射片16、扩散板401、光学膜片402、液晶面板5以及前框17等部件。如图3所示，平面背壳2与边框1远离出光面3的一侧固定连接，前框17与边框1靠近出光面3的一侧固定连接，平面背壳2、边框1和前框17形成一容纳腔，对容纳于其内的灯组15、反射片16、扩散板401、光学膜片402和液晶面板5等起到支撑和空间定位的作用。
如图3所示，在平面背壳2、边框1和前框17形成的容纳腔中，灯组15、反射片16、扩散板401、光学膜片402、液晶面板5沿远离平面背壳2的方向依次放置，其中，光学膜片402可以为一张或叠置的多张。灯组15可以采用LED(Light Emitting Diode，发光二极管)灯组，如包括多个LED芯片151的LED灯条或LED灯板。反射片16在与LED芯片151相对的位置具有孔161。灯组15与反射片16组装后，LED芯片151穿过反射片16上开设的孔161，其发出的光线直接射向扩散板401。扩散板401对光线有光学扩散、均匀化的作用。经过扩散板401的光线再通过光学膜片402的增亮和雾化，可以达到更高的亮度和均一度，从而为液晶面板5提供更高质量的背光。
本公开实施例的显示装置，可以壁挂安装，也可以通过底座直接放置在台面上。由于背壳为平面形状并且嵌入在边框内侧，使得显示装置的外观更加纤薄。如图8所示，当采用壁挂安装方式时，显示装置100可以几乎与墙壁贴合，显示装置的背面也不易积灰，安装效果较佳。
在本公开实施例中，平面背壳与边框的固定方式不限。例如，平面背壳可以通过沉头螺钉与边框远离出光面的一侧固定连接。在图3所示的实施例中，第一凸起102呈板状，平面背壳2与第一凸起102远离出光面3的表面粘接。这样，可以减少在平面背壳2上的螺钉孔数量，从而使得显示装置的背面较为美观。
如图3和图4所示，在本公开的该实施例中，边框1还包括从边框本体101内壁延伸出的第二凸起103，第二凸起103包括第一台阶部1031和第二台阶部1032，第一台阶部1031比第二台阶部1032更加靠近边框本体101，且第一台阶部1031平行于出光面3的阶面比第二台阶部1032平行于出光面3的阶面更加靠近出光面3；显示装置的光学结构层4位于第二台阶部1032靠近出光面3的一侧且位于第一台阶部1031的内侧，显示装置的液晶面板5位于第一台阶部1031靠近出光面3的一侧且位于边框本体101的内侧。其中，光学结构层4包括沿远离平面背壳2的方向依次设置的扩散板401和至少一张光学膜片402，光学膜片402例如为棱镜片或扩散片。
液晶面板5通过第一台阶部1031、边框本体101和前框17在空间中定位。在组装液晶面板5之前，还需要对光学结构层4进行空间定位。请结合图4、图5和图6所示，第一台阶部1031靠近出光面3的一侧具有第一卡接插槽1033，第二台阶部1032靠近出光面3的一侧具有第二卡接插槽1034；显示装置还包括定位弹片6，定位弹片6包括第一卡接板部601、第二卡接板部602和连接板部603，第一卡接板部601与第一卡接插槽1033卡接，第二卡接板部602与第二卡接插槽1034卡接，且第二卡接板部602具有平行于出光面3延伸的条形插孔604；扩散板401和光学膜层402的边缘具有凸耳4011，凸耳4011插装于条形插孔604内。
在本公开实施例中，每个定位弹片6与一个第一卡接插槽1033和一个第二卡接插槽1034卡接。如图6所示，扩散板401在边缘设计有四个凸耳4011，左右各两个而且呈不对称分布，这样可以防止组装时放反。光学膜层402的结构与扩散板401类似，并且其凸耳分布位置与扩散板401相一致。如图4所示，扩散板401和光学膜层402的位于同一位置的凸耳插装于一个定位弹片6的条形插孔内。如图3和图4所示，由于扩散板401和光学膜层402左右凸耳的不对称设计，左侧第一台阶部1031和第 二台阶部1031的截面不会看到第一卡接插槽1033和一个第二卡接插槽1034，而右侧第一台阶部1031和第二台阶部1031的截面可以看到第一卡接插槽1033和一个第二卡接插槽1034。
如图5所示，第一卡接板部601和第二卡接板部602相背离的一侧分别具有凸起的卡钩605，第一卡接插槽1033和第二卡接插槽1034内分别对应设置有卡钩槽，通过卡钩605和卡沟槽的配合实现定位弹片在边框上的安装。
在组装扩散板401之前，首先将定位弹片6与边框1组装，然后将扩散板401的凸耳4011插装于定位弹片6的条形插孔604内，将扩散板401置于第二台阶部1032的平行于出光面3的阶面上。之后，采用类似的方式组装光学膜片402。光学结构层4(即扩散板401和各个光学膜片402)组装完毕后，通过第一台阶部1031、第二台阶部1032和定位弹片6在空间中定位。
定位弹片6可以为金属定位弹片或塑料定位弹片。定位弹片6的数量和具体设置位置不限，可以根据显示装置的规格尺寸进行相应设计。例如，在一个实施例中，定位弹片为4个，其中2个定位弹片设置在边框的左侧边部，另外2个定位弹片设置在边框的右侧边部。
如图5所示，第一台阶部1031平行于出光面3的阶面具有用于容纳连接板部603的沉槽1021，沉槽1021的深度不小于连接板部603的厚度。这样，连接板部603不会凸出于第一台阶部1031的平行于出光面3的阶面，可以减少对液晶面板5造成的损伤。
如图2a和图2b所示，在本公开的一实施例中，边框1的地侧支撑架部1b在靠近出光面的一侧固定有逻辑电路板7(T-CON板)和源电路板8(SOURCE板)。其中，源电路板8与液晶面板5通过柔性电路板连接，并在组装后折向反射片16的背侧。在本公开实施例中，逻辑电路板7和源电路板8在垂直于出光面3的方向上至少部分重叠。这样，可以减少逻辑电路板7和源电路板8在地侧支撑架部1b上的占用面积，优化地侧支撑架部1b上电子元件的布局设计。
此外，地侧支撑架部1b在靠近出光面的一侧还固定有喇叭9和转接出线板10。喇叭9与逻辑电路板7、源电路板8和转接出线板10等电路板在垂直于出光面的方向上不重叠。喇叭9的数量可以为多个，可以相对显示装置的纵向中心轴线对称设置，从而提升出声效果。
在一个实施例中，地侧支撑架部1b的左右两端还固定有一对底座安装支架11。 该一对底座安装支架11具有开口朝向地侧的安装插口。该一对底座安装支架11隐藏于显示装置内部，不会影响到显示装置的壁挂安装效果。当显示装置不需要壁挂安装，而是希望通过底座直接放置在台面上时，将相匹配的的底座(图中未示出)插入一对底座安装支架11的安装插口即可。显示设备的使用者可以根据实际情况灵活选择显示装置的安装方式。
如图7所示，在本公开的一个实施例中，显示装置100还包括外接主机12，该外接主机12集成有主板121、至少一个操作按键122和至少一个接口123。通过将主板121、操作按键122和接口123置于一外接主机12中，可以简化显示装置主体的结构设计，使其厚度更小，外观更加纤薄。外接主机12可以通过线缆与显示装置主体有线连接，或者通过蓝牙等无线方式与显示装置主体无线连接。外接主机12可以放置在台面上，并且可以在一定范围内灵活移动，从而提高了使用的便利性。
如图8、图9和图10所示，在本公开的一个实施例中，显示装置100用于壁挂安装，显示装置还包括：用于与墙壁固定连接的壁挂板13，壁挂板13具有多个挂孔131；以及，固定于平面背壳远离出光面的一侧的多个挂接件14，多个挂接件14能够挂装于壁挂板13的对应位置的多个挂孔131中。
如图9和图10所示，挂接件14可以采用螺栓，挂孔131包括相联合的第一部分131a和第二部分131b，第一部分131a的孔径大于螺栓的螺帽141的直径，第二部分131b比第一部分131a更加靠近显示装置的地侧，第二部分131b的孔径大于螺栓的螺杆142的直径且小于螺栓的螺帽141的直径。
显示装置壁挂安装时，首先将壁挂板13通过膨胀螺栓固定于墙壁；然后，抬起显示装置，将显示装置背侧的各个用作挂接件14的螺栓插入挂孔131的第一部分131a；慢慢松手后，在重力作用下，螺栓落入挂孔131的第二部分131b，从而防止从挂孔131中脱出。该安装方式不但简便，而且可靠、安全。当需要将显示装置从墙壁上拆下时，将显示装置抬起，使螺栓进入挂孔131的第一部分131a，取出显示装置即可。
在本公开上述各实施例中，显示装置的具体类型不限，例如可以为电视机或画屏等。显示装置可以壁挂安装或者通过底座直接放置在台面上，当采用壁挂安装方式时，显示装置可以几乎与墙壁贴合，背面也不易积灰，安装效果较佳。
至此，已经详细描述了本公开的各实施例。为了避免遮蔽本公开的构思，没有描述本领域所公知的一些细节。本领域技术人员根据上面的描述，完全可以明白如何实 施这里公开的技术方案。
虽然已经通过示例对本公开的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本公开的范围。本领域的技术人员应该理解，可在不脱离本公开的范围和精神的情况下，对以上实施例进行修改或者对部分技术特征进行等同替换。本公开的范围由所附权利要求来限定。
