As a type of LCD display device, there are many parameters for the high brightness LCD screen module. From a large classification, it can be divided into panel parameters, functional parameters, power parameters, interface parameters, working parameters, etc. Among them, the panel parameters are slightly more important and can be further divided into panel type, display size, display ratio, display color, resolution, brightness, contrast, viewing angle, response time, service life, etc Physical stitching and so on.
So, what does the contrast in the parameters of LCD splicing screen refer to? How important is it in the parameters of the high brightness LCD screen module panel? Let's learn more with the editor below.
The definition of contrast refers to the brightness ratio between the brightest (white) and darkest (black) of the same point on the display screen. To put it bluntly, the higher the contrast, the more vibrant the colors that the screen can present. For example, the current contrast ratio of LCD screens is at least 4000:1, which means that the ratio span between the brightest and darkest reaches 4000. This is a parameter that fully reflects the display performance of high brightness LCD screens. Therefore, the minimum resolution that LCD splicing screens can display is often 1920 * 1080P, which is ultra clear.
So, is the higher the contrast of the LCD splicing screen, the better? The answer is not necessarily.
The higher the contrast of a high brightness LCD screen, the wider the color gamut it can display. It does not directly indicate that the displayed image is more beautiful, because this is also related to the backlight source. Only when the panel contrast and excellent backlight source brightness are reasonably matched can a full, bright, clear, and delicate image texture be achieved. It is precisely because these technologies are constantly improving that the clarity of the images we see now is getting higher and higher, and the quality experience is also getting better and better.
In short, not only high brightness LCD displays, but also widely used displays in daily life have the parameter contrast, which is clearly a very important parameter indicator.
