The LCD module smoothes the image screen

2017-01-05

Liquid crystal is a substance intermediate between solid and liquid. It doesn't glow on its own, so it needs an extra light source. Therefore, the number of lamps and LCD brightness related. The earliest LIQUID crystal displays had only two upper and lower lights. So far, the lowest of the popular styles is four lights, and the high end is six. 4 lamp design is divided into 3 kinds to put means: one kind is 4 sides each put a lamp, the shortcoming is there will be shadow among. The solution is to arrange four lights from top to bottom. The last one is a "U" shaped placement, which is actually two tubes disguised as two lights. The six-light design actually uses three lights. The manufacturer bent three lights into a "U" shape and then placed them parallel to each other to achieve the effect of six lights.

Response time refers to the response time of the liquid crystal display to the input signal, that is, the response time of the liquid crystal from dark to bright or from bright to dark, usually in milliseconds (ms). To figure this out, we have to start with the human eye's perception of moving images. The human eye has a phenomenon called "visual residue," in which high-speed movie images form short-term impressions in the brain. Animation, film and other recent games use the principle of visual residue, which allows a series of progressive images to be presented to people in rapid succession, forming a moving image. The acceptable display speed of images is generally 24 frames per second, which is how movies play at 24 frames per second. If the display speed is lower than this, people will obviously feel the pause and discomfort. By this metric, the display time of each image needs to be less than 40ms. As a result, the response time of 40ms becomes a barrier for LCD displays, and displays smaller than 40ms will have obvious "wake" or "afterimage" phenomena, which makes people feel confused. If you want smooth images, you need to get up to 60 frames per second
