为什么CRT时代没有“拖影”这个概念?LCD的拖影是如何形成的呢?要理解这一点,得从LCD、CRT的工作原理说起。CRT不存在“拖影”先来看看CRT,右图是CRT显像管的内部大致结构,它跟我们家里的电视机显像管差不多。其运行原理很简单:CRT显像管使用电子枪发射高速电子,经过垂直和水平的偏转线圈控制高速电子的偏转角度,最后高速电子击打屏幕上的磷光物质使其发光,通过电压来调节电子束的功率,就会在屏幕上形成明暗不同的光点。
Why CRT era, there is no “smear” concept? LCD smear is how to do it? To understand this, we must start from the LCD, CRT working principle. CRT does not exist “smear” first look at the CRT, CRT picture on the right is the internal structure of the general, it is almost like our TV tube. The operating principle is very simple: CRT tubes use electron guns to emit high-speed electrons, which are controlled by vertical and horizontal deflection coils to control the deflection angle of high-speed electrons. Finally, the high-speed electrons strike the phosphors on the screen to emit light and regulate the power of the electron beams by voltage , It will form a different light and shade on the screen.
