led顯示屏和大屏幕電視區別

區別很大。

LED電(dian)視(shi)機說穿了(le)就(jiu)是采用LED燈作為背光源的LCD液晶(jing)電(dian)視(shi)。

LED是(shi)(shi)光管二極(ji)管，它的(de)光電(dian)轉換效(xiao)率高，使用(yong)壽命長，所以(yi)作(zuo)為背光源(yuan)，而(er)LCD是(shi)(shi)液態二極(ji)管，它本身不發光，需(xu)要光源(yuan)，以(yi)前的(de)LCD電(dian)視(shi)都是(shi)(shi)使用(yong)熒光燈(deng)，現(xian)在(zai)所謂(wei)的(de)LED電(dian)視(shi)就(jiu)是(shi)(shi)將熒光燈(deng)換成了LED等(deng)。

LED大(da)屏幕是用(yong)LED燈(deng)珠作為顯示(shi)(shi)像(xiang)素點拼(pin)接而成的(de)大(da)型顯示(shi)(shi)屏。
