What should be noted when purchasing small-pitch LED displays?

　　The advancement and development of LED technology have LED the market to develop new products. The user experience of small-pitch LED displays is very good. Broadly speaking, small-pitch LED is a screen with a dot pitch of less than 2.5mm. So, compared with traditional LED, what improvements does small-pitch LED display have in terms of user experience? In essence, small-pitch LED displays have improved to a certain extent in terms of the brightness, fineness of the picture quality, resolution, pixels, picture fidelity and uniformity of the displayed images.

　　So, how should one choose a small-pitch LED display?

　　First, understand the common specifications of small-pitch LED displays, such as P2.5, P2.0, P1.875, P1.667, P1.579, and even smaller ones like P0.9375. The smaller the dot pitch, the better the presentation effect in terms of brightness, fineness and other aspects. Of course, the editor also wants to tell you that since the smaller the dot pitch, the higher the technical requirements, the smaller the dot pitch, the higher the cost will also be. When choosing the dot pitch, you should select it based on your own needs. There is a commonly used formula for dot pitch that can be used as a reference: Appropriate visible distance = dot pitch /0.3-0.8.

　　Second, when choosing a small-pitch LED display screen, it is necessary to observe its gray scale. The so-called gray scale is a primary color of the LED display screen, which is divided into 256 grades from dim to bright. Simply put, the gray scale grade reflects the number of colors on the screen. The more colors there are, the higher the gray scale, and the finer the picture display and the higher the color saturation. Since small-pitch LED displays are generally used more indoors, the brightness will be reduced. And a decrease in brightness usually causes damage to the screen's gray scale. Therefore, when choosing a small-pitch LED display, you can observe its gray scale and color saturation.

　　When choosing a small-pitch LED display, it is also necessary to pay attention to its pixel density. The smaller the dot pitch of the LED display, the higher the resolution will be. The higher the resolution, the higher the requirements for the control card. Here, the editor lists the pixel densities of several common specifications for everyone.
