# 3. 垂直同步

- Vsync，垂直同步
|
||||
|
||||
- Vsync，垂直同步又称场同步（Vertical Hold）
|
||||
|
||||
```
|
||||
垂直同步又称场同步（Vertical Hold），从CRT显示器的显示原理来看，单个像素组成了水平扫描线，水平扫描线在垂直方向的堆积形成了完整的画面。
|
||||
显示器的刷新率受显卡DAC控制，显卡DAC完成一帧的扫描后就会产生一个垂直同步信号。
|
||||
我们平时所说的打开垂直同步指的是将该信号送入显卡3D图形处理部分，从而让显卡在生成3D图形时受垂直同步信号的制约。
|
||||
|
||||
当我们选择"等待垂直同步信号"（即打开垂直同步）时，显卡绘制3D图形前会等待垂直同步信号，

- CRT显示器学名为“阴极射线显像管”，是一种使用阴极射线管（Cathode Ray Tube）的显示器。

```

屏幕上的图形图像是由一个个因电子束击打而发光的荧光点组成
|
||||
|
||||
电子枪从屏幕的左上角的第一行(行的多少根据显示器当时的分辨率所决定，比如800X600分辨率下，电子枪就要扫描600行)开始，从左至右逐行扫描，
|
||||
第一行扫描完后再从第二行的最左端开始至第二行的最右端，一直到扫描完整个屏幕后再从屏幕的左上角开始，这时就完成了一次对屏幕的刷新，周而复始。

- 液晶显示器借助于薄膜晶体管驱动的有源矩阵液晶显示器，它主要是以电流刺激液晶分子产生点、线、面配合背部灯管构成画面。
|
||||
|
||||
```
|
||||
|
||||
在电场的作用下，利用液晶分子的排列方向发生变化，使外光源透光率改变（调制），完成电一光变换，
|
||||
再利用R、G、B三基色信号的不同激励，通过红、绿、蓝三基色滤光膜，完成时域和空间域的彩色重显。
|
||||
|
||||
LCD的刷新率与CRT不同，因为LCD和CRT的显像方式不同，CRT是靠不断刷新画面来使显示器显示图像的，而LCD只要改变发光颗粒就能使显示器中的画面动起来
|
||||
正是由于LCD与CRT显像方式不同，LCD显示器本身不会出现屏幕闪烁的现象
|
||||
|
||||
打开垂直同步可以使得画面平滑、稳定。
|
||||
关闭垂直同步，则可以明显提高帧数，获得更快的速度，代价就是牺牲稳定性，显卡持续高负荷运转势必发热，进而影响计算速度。
