Many users can’t tell the difference between small spacing LED screen, LED LCD panel, PDP plasma panel, DLP rear projection panel. tells you the most intuitive, the biggest difference is that small spacing LED screen can’t see the gap, while other display methods have large or small gaps! Specific parameters by the mini photoelectric small series for you to introduce in detail, please look down!
The first is led small spacing?
We all know that led is composed of LED beads, and the distance between the center points of two LED beads is called the point spacing. The display industry generally adopts the method of defining product specifications according to the distance, such as P5, P4, P2 (the point spacing is 5mm, 4mm and 2mm respectively), etc. with the progress of the process, the point spacing becomes smaller and smaller. According to the value of 52dp parameter of playing large screen, the display screen with point spacing less than 2mm is small, the display screen with point spacing greater than 2mm is defined as ordinary display screen, and the display screen with point spacing less than 1mm is defined as mini led. In the current mass-produced display screen, the minimum point spacing is P0.4, that is, the distance between the center points of two lamp beads is only 0.4mm.
What are the advantages of small space LED display?
1. Seamless splicing
Splicing large screen display technology can not avoid the influence of physical frame when meeting the customer’s needs to the maximum extent. Even if the ultra narrow edge did professional LCD screen, there is still a very obvious splicing seam. Only led display can make the splicing seam meet the seamless requirements, and the advantages of high-density and small spacing led seamless splicing can be highlighted.
2. High brightness intelligent adjustable
LED screen has high brightness, in order to meet the strong light environment and dark light environment to give the viewer comfortable viewing effect, avoid visual fatigue, can cooperate with the light sensing system for brightness adjustment.
3. High gray level and better color performance
Even in the low brightness, the gray performance of the display screen is almost perfect, and the level and brightness of the display screen is higher than that of the traditional display screen, which can also show more image details without information loss.
4. High contrast, faster response, high refresh rate
The higher the scanning times and the higher the refresh rate, the better the stability of the displayed image (picture). The lower the refresh rate, the more severe the flicker and jitter of the image, and the faster the eye fatigue. Led small spacing screen in high refresh, stable picture, no wavy black screen, clear image edge, accurate restoration of real image information.
How to select the LED small spacing?
Size and resolution of point spacing:
The size and resolution of point spacing are the most important factors when people buy. In practice, the smaller the point distance is, the higher the resolution is, and the better the practical application effect is. The smaller the point spacing of LED small spacing display products, the higher the resolution and the higher the price. Users should fully consider their application environment and program budget when purchasing products to avoid the dilemma of spending a lot of money but not achieving the expected effect.
Maintenance cost:
When users choose led small spacing display products, not only the purchase cost but also the high maintenance cost should be considered. In practice, the larger the screen size is, the more complex the maintenance process is, and the maintenance cost will increase accordingly. In addition, the power consumption of small spacing is not easy to be reduced, and the operating cost of large size led small spacing display is usually higher.
The compatibility of LED small spacing signal transmission is very important
The indoor signal access of LED small spacing display has the requirements of diversification, large number, scattered location, multi signal display on the same screen, centralized management and so on. In actual operation, if the display wants to be applied efficiently, the signal transmission equipment must not be despised. In the display market, not all led small spacing displays can meet the above requirements. When choosing products, we should not pay one-sided attention to the resolution of products, and should fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.
