1、大屏幕顯示設備尺寸和可視顯示尺寸大屏幕顯示尺寸：指顯示設備的可見部分的對角線尺寸。國際慣例以英寸為單位來計量。大屏幕可視尺寸：指顯示設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備的長和寬顯示設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的顯示設備和16:9的顯示設備。常見的顯示器和電視機為4:3的顯示設備，新推出的等離子、高清液晶電視為16:9的顯

2、示設備。一般情況同樣尺寸的4:3的顯示設備的面積比16:9的顯示設備的面積要大。4:3大屏幕顯示設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.
