We all know that led is composed of led lamp beads, and the distance between the center points of two led lamp beads is called the dot pitch. The LED display industry generally defines the product specifications according to the distance. For example, we commonly use P12, P10, P8, and the dot spacing between them is 12mm, 10mm and 8mm, which is smaller than the LED display of P2.5. It is a small-pitch LED display. With the improvement of technology, the smaller the dot pitch, the more expensive it is.
Small-pitch LED displays are usually used indoors, so they are also called indoor small-pitch LED displays, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25 , P1.0 and so on. For a product like this, what are its highlights worthy of our attention? Let's take a look next.
1. Seamless splicing
The splicing large-screen display technology can not avoid the influence of the physical frame when it meets the needs of customers to the maximum. Even the ultra-narrow-edge DID professional LCD screen still has very obvious splicing seams. Only the LED display makes the splicing seam possible. Seam requirements, the advantages of seamless splicing of high-density small-pitch leds can be highlighted.
2. Intelligent adjustable high brightness
The led screen itself has high brightness, in order to meet the comfortable viewing effect for the viewer in the strong light environment and the dark light environment, and to avoid visual fatigue, the brightness can be adjusted with the light sensing system.
3. High gray level and better color performance
Even at low brightness, the grayscale performance of the display screen is almost perfect, and the image level and vividness of the display is higher than that of the traditional display screen, and it can show more image details without loss of information.
4. High contrast, faster response speed and high refresh frequency
The number of times the electron beam repeatedly scans the image on the screen. The higher the number of scans and the higher the refresh rate, the better the stability of the displayed image (picture). The lower the refresh rate, the more flickering and shaking the image, and the faster the eyestrain. Under high refresh rate, the small-pitch LED screen can capture images stably, without ripples and black screens, with clear image edges, and accurately restore the true information of the image.
5. Naturalization of color restoration
Adopting the internationally leading point-by-point correction technology, using the LED light-emitting principle, completely retaining the authenticity of the color, avoiding the color loss and deviation caused by other display technologies such as the backlight projection material and the light running path, and realizing the true color reproduction .
6. Three-dimensional visual experience
When the customer chooses to use the 3D playback mode, the splicing wall will present stunning high-definition images, whether live TV, exhibition display, or digital advertising, can fully interpret the wonderful vision, allowing the audience to enjoy an extraordinary visual experience. At present, many shopping malls have already applied such 3D scenes, such as the naked-eye 3D display in Chengdu Taikoo Li, the naked-eye 3D curved display on Beijing Road in Guangzhou and other actual cases. Although these dot pitches are somewhat large, their principles are the same, so small pitch LED displays can also achieve such a three-dimensional effect of visual experience.
