How to choose a small-pitch LED display?
The progress and development of LED technology allow the market to develop new products. The user experience of small-pitch LED displays is very good. In a broad sense, small-pitch LEDs are screens with a dot pitch of less than 2.5mm. What are the improvements compared to LEDs? In fact, small-pitch LEDs have a certain degree of improvement in the brightness, fineness, resolution, pixel, picture restoration and uniformity of the playback picture.
So, how to choose a small-pitch LED display?
1. Understand the common specifications of small-pitch LED displays, P2.5, P2.0, P1.875, P1.667, P1.579, and P0.9375. The smaller the dot pitch, the better the presentation effect in terms of brightness and fineness. Of course, because the smaller the dot pitch, the higher the technical requirements, the smaller the dot pitch, the higher the cost. When choosing the point spacing, you should choose it according to your own needs. There is a common formula for the point spacing that can be used as a reference: good visual distance = point spacing/0.3-0.8.
2. When choosing a small-pitch LED display, it is necessary to observe its grayscale. The so-called grayscale is a primary color of the LED display. It is divided into 256 levels from no light to bright. Simply speaking, the gray level reflects the screen. The number of colors, the more the number of colors and the higher the grayscale, and the finerness of the screen display, the higher the color saturation. Because small spacing is generally used indoors, the brightness will be reduced, and reducing the brightness will generally damage the grayscale of the screen, so when choosing small spacing LEDs, you can observe its grayscale and color. saturation.
3. When choosing a small-pitch LED, you should also pay attention to its pixel density. The smaller the dot pitch of the LED, the higher the resolution, and the higher the resolution, the higher the requirements for the control card. Here to help you list several common specifications of the pixel density. P2.5: 160000 (points/m*2) P2.0: 250000 (points/m*2) P1.875: 284444 (points/m*2) P1.667: 360000 (points/m*2) P1. 579:401111 (points/m*2) P0.9375:1137777 (points/m*2).
