What is the contrast in the LCD splicing screen parameters?


As a high-end display device, there are many LCD splicing screen parameters. From the big classification, it can be divided into panel parameters, function parameters, power parameters, interface parameters, working parameters, etc., of which the panel parameters are slightly more. And the most important, it can be subdivided into panel type, display size, display ratio, display color, resolution, brightness, contrast, viewing angle, response time, service life, physical stitching, and so on.




So, what is the contrast in the LCD splicing screen parameters? How important is it in the LCD splicing screen panel parameters?




The definition of contrast refers to the brightness ratio of the same point on the display screen when it is the brightest (white) and the darkest (black). Let's be straightforward: the higher the contrast, the higher the degree of vividness the screen can present. For example, the current contrast ratio of the LCD splicing screen is at least 4000:1, which means that the ratio between the brightest and the darkest reaches 4000. This is a parameter that can fully reflect the display performance of the LCD splicing screen, so the LCD splicing screen can The lowest resolution of the displayed pictures often reaches the ultra-clear 1920*1080P.




So, is the higher the contrast of the LCD splicing screen, the better? The answer is not necessarily!




The higher the contrast of the LCD splicing screen means the wider the color gamut it can display, it does not directly mean that the display screen is more beautiful, because it is also related to the backlight light source, only when the panel contrast and excellent backlight brightness are both reasonably matched , In order to be able to get full color, bright, clear and delicate picture texture. It is precisely because of the continuous improvement of these technologies that the definition of movies that everyone sees is getting higher and higher, and the texture experience is getting better and better.




In short, not only LCD splicing screens, but also screens that are widely used in life basically have the parameter of contrast. Obviously it is a very important parameter index. The follow-up will gradually explain the related parameters of other LCD splicing screens. Knowledge, I hope to help everyone!
