The difference between the two is:
1. Different screen response speeds: the mobile phone screen response speed with 120 Hz sampling rate is faster. The higher the sampling rate is, the faster the screen response speed is.
2. Different smear lengths: the longest smear length of 90hz refresh rate display screen is 09mm, and the response time is controlled at 14ms, while the longest smear length of display screen supporting 120Hz refresh rate is only 07mm, and the response time is controlled at 11ms, which is at the leading level in the industry among screens with the same refresh rate.
3. Different test speeds: the drag length of LED display screen supporting 90hz refresh rate is 1 / 5 shorter than that of 90hlcd display screen, reaching the same level as that of LCD display screen supporting 120Hz refresh rate, while the drag length of OLED screen supporting 120Hz refresh rate is 1 / 3 shorter than that of 120Hz LCD screen, So as to ensure that the picture will not be blurred due to dragging under the high-speed movement of high refresh rate.
The refresh rate refers to the number of times the electron beam repeatedly scans the image on the screen. The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine its price, but because the refresh rate and resolution restrict each other, only when the high refresh rate is reached at the high resolution can the display be called excellent performance.
