大屏幕尺寸计算方法

1、大屏幕显示设备尺寸和可视显示尺寸大屏幕显示尺寸：指显示设备的可见部分的对角线尺寸。国际惯例以英寸为单位来计量。大屏幕可视尺寸：指显示设备可以显示图象部分对角线尺寸。以普通显示器为例：15"CRT显示器的显像管的对角线为15英寸，它的可视尺寸在13.8英寸左右。19"LCD液晶显示器的液晶板的对角线为19英寸，它的可视尺寸在18英寸左右。最常见的大屏幕显示设备的长和宽显示设备通常以对角线的长度来衡量，以英寸单位（1英寸=2.54cm）,长和宽之比有两个尺寸，4:3的显示设备和16:9的显示设备。常见的显示器和电视机为4:3的显示设备，新推出的等离子、高清液晶电视为16:9的显

2、示设备。一般情况同样尺寸的4:3的显示设备的面积比16:9的显示设备的面积要大。4:3大屏幕显示设备尺寸换算表对角线4318.364:3对角线（mm）宽（mm）高(mm)面积（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.
