Explanation of LCD display response time parameters
Date:2019-09-16
Previously, we introduced the brightness and contrast of LCD screen. Today, we are going to analyze the parameters of response time of LCD screen. When many terminal products develop LCD screen, they will pay attention to the parameter response time. Today, let's talk about the response time of LCD screen.
The so-called black-and-white response time of LCD is the response speed of each pixel of LCD to the input signal, that is, the time required for the pixel to turn from dark to bright or from light to dark (its principle is to apply voltage to the liquid crystal molecules to make the liquid crystal molecules twist and recover). 25ms and 16ms are the response time. The shorter the response time is, the less the user will feel the trailing shadow when watching the dynamic picture. Generally, the black-and-white response time is divided into two parts: rise time and fall time.
The response time of LCD screen has been shortened from 25ms to 16ms, and then to 12ms or even 8ms. The old idea that LCD screen is not suitable for entertainment is facing a great challenge. You can do a simple conversion: 30 ms = 1 / 0.030 = 33 frames per second; 25ms = 1 / 0.025 = 40 frames per second; 16 Ms = 1 / 0.016 = 63 frames per second; 012 = 83 frames per second. It can be seen that the birth of 12ms means a great progress in LCD display manufacturing.
