Description

一种显示装置后壳和显示装置 技术领域
本公开的实施例涉及一种显示装置后壳和显示装置。
背景技术
平板显示装置，例如薄膜晶体管液晶显示器(Thin Film Transistor Liquid Crystal Display，TFT-LCD)或有机发光二极管(Organic Light Emitting Diode，OLED)显示器，具有厚度薄、功耗低、无辐射等特点，近年来得到了迅速地发展，广泛应用于电脑显示器产品、电视产品或者大屏幕公共显示产品。
平板显示装置通常包括：用于显示图像的显示面板、用于保护该显示面板的正面的前框和用于保护显示面板背面的后壳。对于TFT-LCD而言，后壳还用于容纳背光模组。近年来，平板显示装置的尺寸不断增大(例如100英寸或以上的平板显示装置)，因此平板显示装置的后壳的尺寸也随着平板显示装置的尺寸增大而增加。平板显示装置的后壳通常整体由金属压制或注塑工艺形成，当后壳尺寸过大时，需要增大压制机的尺寸，而且，生成的后壳容易产生扭曲和/或弯曲而造成损坏，且不利于运输。上述因素造成平板显示装置的后壳开模周期长且成型困难。

在根据本公开的一个实施例中，第三壳体3的两侧边具有分别与第一壳体1和第二壳体2搭接的搭接面8。图5为第三壳体3的搭接面8的局部放大示意图，该放大示意图为图4所示的第三壳体3的虚线31对应部位的局部放大示意图。搭接面8与第三壳体3的主体形成阶梯结构，各搭桥7设置于搭接面8上。在该实施例中，第三壳体3的侧边具有搭接面8，与第一壳体1和第二壳体2的侧边搭接，而且第三壳体3的卡扣与第一壳体1和第二壳体2上的卡槽41连接，使第三壳体3不易脱落，第一壳体1、第二壳体2和第三壳体3三者之间的结构能够承受较大的形变压力。
在根据本公开的一个实施例中，第三壳体3的底部具有与第一壳体1的第一固定部11和第二壳体2的第二固定部21配合形成的结构相配合的阶梯面32。在该实施例中，第三壳体3的底部的阶梯面32，与第一壳体1的第一固定部11和第二壳体2的第二固定部21配合形成的结构配合，结合第三壳体3与第一壳体1和第二壳体2通过卡扣42和卡槽41连接方式、第三壳体3的侧边搭接结构，使第三壳体3不易脱落，第一壳体1、第二壳体2和第三壳体3三者之间的结构能够承受较大的形变压力。
第一壳体1、第二壳体2和第三壳体3组装后的示意图如图6和图7所示。在图6示出的组装后的显示装置后壳外表面的视觉效果图中，第一壳体1、第三壳体3和第二壳体2横向依次排列。在图7示出的组装后的显示装置后壳内表面的视觉效果图，第二壳体2、第三壳体3和第一壳体1横向依次排列。
此外，还可以在第三壳体3上设置用于粘贴、嵌入或热熔标识图形的区域或镂空。例如，可以在第三壳体3上设置与标识图形相同的镂空图案，同样形状和大小的标识图形嵌入或热熔至该镂空，该标识可以采用各种颜色。各壳体上还可以设置用于壁挂的孔洞，用于安装壁挂固定件。
本公开的实施例可产生以下有益效果：显示装置后壳包括多个可分离的壳体，各壳体通过彼此连接即可形成完整的显示装置后壳，可分离的壳体相对完整的显示装置后壳尺寸明显示减小，有利于缩短开模周期和降低成型难度；同时，第一壳体的底部朝向第二壳体延伸，第二壳体的底部朝向第一壳 体延伸，二者连接后形成“U”形结构，第三壳体设置于第一壳体和第二壳体所形成的“U”形结构中，从而使三者在组合后更紧固，能够承受较大的形变压力。
本公开的至少一个实施例还提供一种显示装置，包括一前框，还包括如上实施例提供的显示装置后壳，前框和后壳组装在一起形成显示装置的外壳。
