1、大屏幕顯示尺寸:指顯示設(shè)備的可見(jiàn)部分的對(duì)角線尺寸。國(guó)際慣例以英寸為單位來(lái)計(jì)量。???大屏幕可視尺寸:指顯示設(shè)備可以顯示圖象部分對(duì)角線尺寸。???以普通顯示器為例:15”CRT顯示器的顯像管的對(duì)角線為15英寸,它的可視尺寸在13.8英寸左右。19”LCD液晶顯示器的液晶板的對(duì)角線為19英寸,它的可視尺寸在18英寸左右。?最常見(jiàn)的大屏幕顯示設(shè)備的長(zhǎng)和寬???顯示設(shè)備通常以對(duì)角線的長(zhǎng)度來(lái)衡量,以英寸單位(1英寸=2.54cm),長(zhǎng)和寬之比有兩個(gè)尺寸,4:3的顯示設(shè)備和16:9的顯示設(shè)備。常見(jiàn)的顯示器和電視機(jī)為4:3的顯示設(shè)備,
2、新推出的等離子、高清液晶電視為16:9的顯示設(shè)備。一般情況同樣尺寸的4:3的顯示設(shè)備的面積比16:9的顯示設(shè)備的面積要大。?4:3大屏幕顯示設(shè)備尺寸換算表對(duì)角線16918.364:3對(duì)角線(mm)寬(mm)高(mm)面積(平方米)14”355.60284.48213.360.0615”381.00304.80228.600.0717”431.80345.44259.080.0918”457.20365.76274.320.1019”482.60386.08289.560.1120”508.00406.40304.800.
