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 display industry generally uses the method of defining product specifications according to the distance, such as the commonly used P12, P10, P8 (dot pitches are 12mm, 10mm and 8mm respectively), etc. As the process progresses, the dot pitch is getting smaller and smaller .
Small-pitch LED display refers to indoor LED display with LED dot pitch of P2.5 and below, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1. 25. LED display products such as P1.0. The advantages are as follows:
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 that 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 image information.
5. Naturalization of color restoration
Adopting internationally leading point-by-point correction technology, using the principle of LED light emission, to completely retain the authenticity of colors, avoid color loss and deviation caused by other display technologies such as backlight projection materials and light running paths, and achieve true color reproduction .
6. Three-dimensional visual experience
When the customer chooses to use the 3D playback mode, the splicing wall will present shocking 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.
With the popularization of the concept of 4K and the implementation of standards such as H.265, video surveillance is moving towards high definition, and the requirements for LED displays are getting higher and higher, and we strive to achieve all the video content. Therefore, high-definition, high-quality, low-energy small-pitch seamless splicing LED screens have become the "darling" of the display industry. How to choose? Yangcheng Electronics tells you.
How to choose small LED pitch?
The size and resolution of the dot pitch:
The size and resolution of the dot pitch are the most important factors when people buy. In actual operation, the smaller the dot pitch, the higher the resolution, and the better the actual application effect. The smaller the dot pitch of Maipu brilliant LED small-pitch display products, the higher the resolution and the higher the price. Users should fully consider their own application environment and program budget when purchasing products to avoid the dilemma of spending a lot of money but not achieving the expected results.
When users choose LED small-pitch display products, not only the purchase cost, but also the high maintenance cost must be considered. In actual operation, the larger the screen size, the more complicated the maintenance process, and the maintenance cost will naturally increase accordingly. In addition, the power consumption of the small pitch is not easy to become smaller, and the operation cost of the large-size Maipu brilliant LED small pitch display is usually higher.
LED small pitch signal transmission compatibility is very important:
The indoor signal access of the led small-pitch display has the requirements of diversification, large number, scattered locations, multi-signal display on the same screen, and centralized management. In actual operation, if the display is to be used efficiently, the signal transmission equipment must not be underestimated. In the display market, not all LED small-pitch displays can meet the above requirements. When purchasing products, do not pay attention to the resolution of the product one-sidedly, and fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.
With the continuous development of small-pitch LED display technology, small-pitch display technology is becoming more and more mature. With its advantages, Maipu Guangcai small-pitch LED displays can be used in high-end indoor command and control centers, dispatch centers, monitoring centers, radio and television studios. The application industries that require high image quality, such as laboratories and meteorological information centers, are becoming more and more mature. The maturity of small-pitch technology has led to continuous decline in production costs. At that time, I believe that the price of small-pitch LED displays will become more and more affordable, and it will be just around the corner for all kinds of industries!
