Nowadays, the market of outdoor LED energy-saving display screens is favored by more and more companies. LED display energy-saving screen manufacturers are emerging one after another like bamboo shoots in spring, but not every LED energy-saving display screen company is professional, and various inferior energy-saving display products are appearing on the market.
If merchants want to have a good development in the market, they must have their own unique and high-quality LED outdoor LED energy-saving display screen products.
1. LED energy-saving display screens need to be corrected point by point
The discreteness of LED itself is a natural defect. The LEDs provided by lamp manufacturers have differences in brightness and chromaticity. Due to the flatness of module assembly, the flatness of box assembly; the flatness of the mask, and the discreteness of the ink color; the optical axis direction of LED welding deviates from the normal direction of the display screen, especially the optical axis direction of the direct-inserted LED. In the actual production process, the uniformity of the LED energy-saving display screen will be affected by many factors, so the uniformity of the uncorrected LED energy-saving display screen cannot reach the ideal level, and the picture quality is significantly different from other flat panel display technologies.
After the LED energy-saving display screen has been used for a period of time, due to the difference in individual LED light decay and other external factors, the uniformity will inevitably deteriorate further, which will manifest as a large number of pitting, bright and dark spots, and even mosaics on the display screen, commonly known as the "flower screen" phenomenon.
Point-by-point correction technology allows users to reduce costs and greatly improve the uniformity of the display screen, significantly improving image quality. Before leaving the factory, point-by-point correction is a means of quality improvement, which means the improvement of competitiveness and the expansion of profit space; after being used for a period of time, point-by-point correction can extend the "pleasing life" of the LED energy-saving display screen, create more commercial value for users, and reduce resource waste.
2. Select high-quality LED lamp beads
The high reliability of LED lamp beads means that they can maintain the stability of quality during the entire process of customer use. The use of LED lamp beads can be roughly divided into several links.
The first is the factory inspection link. After passing the final visual inspection and electrical performance test at the production factory, the packaging is shipped out of the factory; the second is the transportation and storage link. After transportation, storage and other links, it can reach the energy-saving display screen factory; then the production and processing link, the screen factory opens the package, and completes the production and processing of the finished display screen through production processes such as board loading and welding; the final is the normal use link. During this process, the LED lamp beads must work reliably and no dead lights can occur.
During this period, the LED lamp beads must be able to withstand the test of moisture expansion and temperature shock, especially the welding temperature shock with a maximum temperature of 260 degrees.
The LED lamp beads are composed of a variety of different materials, such as metal copper, resin, PPA, conductive glue, light-emitting chips, etc. Their moisture absorption expansion coefficient and temperature expansion coefficient are different, so the material matching between them is quite critical. If the matching is improper, dead lights will appear. Therefore, it is necessary to simulate the use process of LED lamps to judge their reliability.
After comprehensively considering the cost-effectiveness of outdoor full-color LED energy-saving display screens, the dot pitch is an element that cannot be ignored.
Generally speaking, the dot pitch of the display screen is not only closely related to the display accuracy, viewing distance, and application site of the screen, but also one of the determining factors of the display screen price. The smaller the dot pitch, the higher the price, and the better the corresponding LED screen effect. So, if the budget allows, is the dot pitch as small as possible?
Tips for Shenzhen LED Energy-saving Display Screen: As long as you have some understanding of the LED energy-saving display screen industry, it is not difficult to find that the appropriate dot pitch of outdoor full-color LED energy-saving display screen is not the smaller the better, but also needs to be considered comprehensively based on the site area, viewing distance, and whether special display effects need to be supported.
Shenzhen Chengtong Optoelectronics is a large-scale LED energy-saving display company with decades of experience. It provides the best economic and reasonable solutions based on the application site and installation height of user LED energy-saving display products.
