The screen refresh rate means the number of times the electron beam scans the screen image repeatedly, that is, the number of times the screen is refreshed per second; the higher the screen refresh rate, the better the stability of the displayed image. , the calculation unit of screen refresh rate is "Hz". When using a refresh frequency above 70Hz, flickering can be basically eliminated.

What does the screen refresh rate mean?
The refresh rate refers to the number of times the electron beam repeatedly scans the image on the screen. Simply put, the refresh rate is the number of times the screen is refreshed per second. The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine its price, but since the refresh rate and resolution are mutually restrictive, only a monitor with a high refresh rate at high resolution can be called excellent performance.
Note that although its calculation unit and vertical scanning frequency are both Hz, these are two completely different concepts. The 75Hz screen refresh rate is the most basic standard set by VESA for flicker-free. The 75Hz here should be a standard that can be achieved in all display modes. For traditional monitors, the lower the refresh frequency, the more severe the image flicker and jitter, and the faster the eyes will tire. Sometimes it can cause sore eyes, dizziness and other symptoms. Because 60Hz is close to the refresh frequency of fluorescent lamps, an uncomfortable stroboscopic effect will occur when the display is at a refresh rate of 60Hz. When using a refresh frequency above 70Hz, flickering can be basically eliminated. Therefore, a refresh rate of 70Hz is the minimum requirement for stable operation of the monitor. Among mobile phone screen refresh rates, the OLED screen refresh rate has a better experience than the LCD screen refresh rate, is smoother, and saves power. LCD high refresh rates will have a smearing effect, which affects the experience. You can understand it this way, the refresh rate is the number of times the screen is refreshed per second. When watching a movie, what we see is actually a still picture, just like a slide show. Why do we feel the picture It is moving because human eyes have a visual retention effect. The impression left in the brain of the previous picture has not disappeared, and the next picture follows immediately, and the difference between the two pictures is very small. The action needs to be displayed with many sub-pictures, so that we feel that the picture is moving. The replacement of each picture is refreshing. Assuming that an action is completed by 20 pictures, we will look a bit like a cartoon, and If this action is increased to 30 pictures, it will look much more natural. This is the refresh rate.Extended knowledge: The impact of refresh rate

小米9屏幕刷新率是60Hz。小米9正面采用6.39英寸AMOLED材质的水滴全面屏,屏幕比例为“19.5:9”,屏幕分辨率为“2340×1080”像素,像素密度为403ppi,屏占比为90.7%,支持广色域显示,NTSC 103.8%(Typ),支持标准模式、阳光屏2.0、夜光屏、无级色温调节;支持256阶护眼模式,通过德国电气工程师协会VDE低蓝光护眼认证。

ipadpro2021的屏幕刷新率是120Hz。iPad Pro 2021是苹果公司于2021年4月21日发布的一款平板电脑,其拥有一项属性就是高刷新率,能为用户带来120Hz的屏幕刷新。iPad Pro 2021搭载了11英寸和12.9英寸的Liquid视网膜显示屏,两种版本屏幕均搭配ProMotion自适应刷新技术和原彩显示。

144Hz指的是显示器每秒的刷新率达到144赫兹;刷新率是指屏幕每秒被刷新(更新)的次数,Hz(赫兹)是其单位。刷新率越高,图像越流畅清晰稳定,对眼睛的影响也小;刷新率越低,图像就会有闪烁抖动,对眼睛有不利影响,尤其是CRT显示器,刷新率较低,会对眼睛有直接的影响,直观感觉就是眼睛疲劳干涩。

荣耀30pro的屏幕刷新率是60Hz。荣耀30 pro采用6.57英寸OLED材质70°黄金曲率的飞瀑屏(左上挖孔的全面屏),屏幕分辨率是1080P,最高的刷新率是60Hz,屏幕比例为“19.5:9”,像素密度为401每英寸像素

2月2日消息,今日,姜海荣发微博称,荣耀Magic6系列屏幕搭载的全域低功耗LTPO护眼屏和荣耀巨犀玻璃,护眼又抗造,值得信赖。近日一博主对荣耀Magic6Pro、三星S24Ultra和iPhone15ProMax三款顶级旗舰机的屏幕进行对比测试。测试过程:1、先把三台手机亮度调到最大,并同时播放HDR视频。结果显示,高动态范围的显示技术(HDR)上荣耀Magic6Pro完全不弱于苹果和三星,其显示亮度和对比度表现较好。2、随后该博主将手机前置挖孔位置都遮住(看不出手机型号),看显示效果。结果:

1、打开手机设置,点击【显示与亮度】选项。2、点击【更多】选项。3、点击【屏幕刷新率】。4、可以开启【智能切换】,也可自行选择刷新率。

屏幕刷新率的意思是电子束对屏幕图像的重复扫描次数,也即屏幕每秒钟画面被刷新的次数;屏幕的刷新率越高,所显示的图像稳定性就越好,屏幕刷新率的计算单位是“Hz”,当采用70Hz以上的刷新频率时可基本消除闪烁。

1、在手机设置菜单中点击【显示】选项。2、点击【屏幕刷新率】。3、勾选【120Hz】或【60Hz】即可。
