24、风格简约、轻薄精致，不仅是眼下主流审美品味，也可避免室内格局的紧张，节省了大面积空间。大屏幕搭载超窄的边框，创造出影院的效果，因此许多消费者都选择了将平板电视进行壁挂放置。 在壁挂液晶电视时，需注意哪些方面? 根据2008年12月1日起实施的家用平板电视接收机安装和维修服务技术规范规定，平板电视的屏幕中心点距地面垂直高度宜在1米-2米范围内;水平方向应在平板电视屏幕法线水平方向60度内;俯仰方向应在平板电视机屏幕法线垂直方向15度内等。 此外，为了保证液晶电视壁挂式安装的安全使用，应当选择厚度大于200毫米的水泥或实心砖墙上使用合适的支架进行。 另外，根据尺寸和重量不同，固定点也有不同，如20

25、至40英寸之间、或20至45千克范围内的平板电视，至少应当采用4个固定点;65英寸以上至少6个，80英寸以上至少9个等。 最后，选择一个合适的壁挂电视托架是十分重要。 首先、搞清楚电视支架的分类，目前市场上支架主要分为可调角度挂架和固定角度挂架。其次、平板电视墙壁挂架应保证平板电视机在安装后的维护、维修方便，在不破坏安装面、安装架的前提下，易于拆卸。买壁挂支架时，一定要检查清楚安装支架是否包括墙体连接部分、产品连接部分、紧固件部分、安装示意图及操作说明，而且一定要符合国际VESA组织FDMI标准。 液晶电视壁挂时如何处理线材? 1、留足空间给接口：由于某些信号线插头比较大，比如某些HDMI插头

26、，在硬插的时候很容易发生接口或者插头损坏的现象。而这种问题多半是使用了一些设计不合理的非原装挂架，这些挂架在设计的时候没有考虑太多的安装问题，所以建议选择设计完善的原装挂架。 2、整理烦乱的连线：电视机纷繁复杂的接口，带来的是各种烦人的连线。如何隐藏电视机挂墙时暴露出的各种接口连线，应该在装修的时候就考虑进去。比如可以在电视墙侧面增加一些挡板或者立体扣件等装饰，让连线从背后过去。如果是装修完成的环境，也可考虑增加一些遮盖性装饰物。 3、选择合理的接口布局：挂墙市安装最麻烦的就是信号线的连接，如果全部接口都在机身背面，那么要更换或者临时增加视频源将非常麻烦。所在选择电视的时候，接口的布局也是您考虑选购机型时的重要要素。最合理的设计应该是在左右侧面或者下接口上，设计有大部分接口。最好的办法还是为每个接口配备延长线，这样过墙的连线就可以固定下来，以后更换信号源只需在其他地方连接就可以了。
