E1421B无功功率不但增加线损和设备的发热，更主要的是功率因数的降低导致电网有功功率的降低，大量的无功电能消耗在线路当中，设备使用效率低下，浪费严重，使用变频调速装置后，由于变频器内部滤波电容的作用，从而减少了无功损耗，增加了电网的有功功率。

红外触摸屏缺点是在球面显示器上使用时感觉不好，这是因为赖以工作的红外光栅矩阵显然要求在同一平面上

E1421B因此，真正感应触摸的工作平面距离弧形的显示器屏幕有较大的间隔，尤其在边角，但是这个缺点在平面显示器上不存在，比如液晶显示器。

E1421B reactive power not only increases the line loss and equipment heating, but more importantly, the reduction of power factor leads to the reduction of the active power of the power grid. A large amount of reactive power is consumed in the line, and the equipment is inefficient and wasted seriously. After the use of variable frequency speed regulation device, the reactive power loss is reduced due to the role of the filter capacitor inside the inverter. The active power of the grid is increased.

The disadvantage of the infrared touch screen is that it does not feel good when used on a spherical display, because the infrared grating matrix on which to work is obviously required to be on the same plane

Therefore, the real touch-sensitive working plane has a large gap from the curved display screen, especially in the corners, but this shortcoming does not exist on flat displays, such as liquid crystal displays.
