本申请提供的实施例中，所述显示装置100还包括双面胶9，安装于所述中框2的三个安装凸板22与所述屏面板4之间，以使所述屏面板4贴接于三个所述安装凸板22上，通过所述双面胶9实现所述屏面板4与所述安装凸板22的粘结，方便结构的安装。
请一并参阅图3、图10和图11，所述显示装置100详细的安装过程如下：
1、将所述背钣1与所述散热器7通过螺接件3紧固；
2、将所述背板1平放搁置在安装平台上，所述背板1的前面朝上；
3、用螺接件3安装所述中框2至所述背板1的前面上，形成所述显示装置100；
4、将所述光学模组5安置于显示装置100的安装腔401内；
5、将所述屏面板4贴接于所述中框2的安装凸板22上；
6、安装下前框6至所述屏面板4的下端前表面；
7、翻转整个显示装置180°，所述屏面板4的前表面朝下；
8、在所述散热器7上安装相关的电子硬件；
9、盖合所述后壳8。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
