大屏幕尺寸計(jì)算方法

1、大屏幕顯示設(shè)備尺寸和可視顯示尺寸大屏幕顯示尺寸：指顯示設(shè)備的可見部分的對角線尺寸。國際慣例以英寸為單位來計(jì)量。大屏幕可視尺寸：指顯示設(shè)備可以顯示圖象部分對角線尺寸。以普通顯示器為例：15"CRT顯示器的顯像管的對角線為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角線為19英寸，它的可視尺寸在18英寸左右。最常見的大屏幕顯示設(shè)備的長和寬顯示設(shè)備通常以對角線的長度來衡量，以英寸單位（1英寸=2.54cm）,長和寬之比有兩個尺寸，4:3的顯示設(shè)備和16:9的顯示設(shè)備。常見的顯示器和電視機(jī)為4:3的顯示設(shè)備，新推出的等離子、高清液晶電視為16:9的顯

2、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)備尺寸換算表對角線4318.364:3對角線（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"508.00406.40304.800.1221"533.40426.72320.040.
