A comprehensive analysis of the terms of LCD.

　　The so-called response time is the speed at which each pixel of the LCD responds to the input signal, that is, the time required for the pixel to turn from dark to bright or from bright to dark. We often say that 25ms and 16ms refer to this response time. The shorter the response time, the less the user will feel dragged by the tail shadow when watching the dynamic picture. Its principle is to apply voltage in the liquid crystal box to make the liquid crystal molecules twist and recover.More importantly, put outdoor lcd display It is imperative for us to make thorough analysis and maximize its social function. https://www.betopview.com/

　　Generally, the response time is divided into two parts: Rise time and Fall time; By response time, we mean the sum of the two. In the early stage of LCD marketing, some nonstandard manufacturers often confuse concepts and regard rise time or fall time as the whole response time to improve product specifications. With the increasing popularity of LCD, consumers are more and more familiar with the knowledge of LCD products, and this behavior of confusing concepts will obviously have less and less market.

　　Importance of response time

　　Why does the response time have an important influence on the display effect? This also starts with the perception of dynamic images by human eyes. As we all know, there is a phenomenon of “visual residue” in the human eye, that is, the picture of high-speed movement will form a short impression in the human brain. Cartoons, movies, etc. Up to now, the latest games just apply the principle of visual residual, so that a series of gradual images can be displayed quickly and continuously in front of people, and then dynamic images can be formed. Generally speaking, the acceptable display speed of pictures is 24 frames per second, which is also the origin of the 24-frame playback speed of movies. If the display speed is lower than this standard, people will obviously feel the pause and discomfort of the pictures. According to this indicator, the display time of each picture needs to be less than 40 ms. In this way, for LCD, the response time of 40ms becomes a hurdle, and the display below 40ms will appear obvious “tailing” or “afterimage” phenomenon.

　　It is not difficult to understand that the shorter the response time, the better. Response time has always been a key purchasing index for users who have high requirements for picture quality. I often hear some friends say that LCD is not suitable for playing games with high frame rate, such as CS and Need for Speed, which is one of the important reasons why many gamers are reluctant to buy LCD. We might as well prove it through some data.
