大屏幕彩电是指屏幕尺寸(对角线)在25～37英寸之间的彩色电视机。它的特点是:图像、伴音质量水平高;遥控功能齐全,具有自动调谐、存储、记忆等功能;附加功能较多,一般均具有全制式功能(即可与卫星接收机、录像机、影碟机配接)、画中画、卡拉OK接口等,扩大了电视机的使用范围。由于具有以上优势,大屏幕彩电已获得越来越多家庭的青睐。但有一点需要提醒大家的是:选用大屏幕彩电一定要考虑家庭的住房条件,一般20平方米左右的房间摆放大屏幕彩电能取得理想的视觉效果。如果房间太小则适得其反。不但难以达到满意的效果,反而影响视力,尤其对儿童的影响较大。另外,房间太小,视觉距离太近,由电视机放射出来的射线、电磁场还会影响儿童的身体健康。因此,采用大屏幕彩电不要追赶时髦,而要根据自己的住房条件、经济实力来决定。
