Development History of Outdoor LED Display Screens

Outdoor LED displays have undergone significant development and changes since their introduction. With the continuous advancement of technology, the application scenarios have gradually expanded, and they have played an important role in advertising, information dissemination and other fields. This article will sort out the development history of outdoor LED displays, focusing on their technological evolution and application expansion.

Early Development: Direct-plug LED Display Screens

Outdoor LED displays initially adopted direct-plug technology, and the three RGB color lamp beads were independently packaged. Although direct-plug LED displays dominated in the early days, they had some obvious defects, such as insufficient display effects and complex installation and maintenance. With the continuous development of lamp bead packaging technology, in order to solve these shortcomings, outdoor surface-mount lamp beads gradually replaced direct-plug lamps and became the mainstream choice for making outdoor LED advertising screens. Here are 3 LED lamp bead specifications.

Technological progress: the rise of surface mount lamp beads

The introduction of surface mount lamp beads (SMD) has greatly improved the performance of outdoor LED displays. The small package size and uniform light emission of surface mount lamp beads can significantly improve the picture quality of the display. At the same time, surface mount technology also simplifies the production process and reduces production costs. The application of surface mount lamp beads not only improves the display effect, but also enhances the stability and durability of LED displays, enabling them to better adapt to complex outdoor environments.

Challenges of conventional outdoor LED displays

Despite the continuous advancement of technology, conventional outdoor LED displays still face some challenges. Regardless of the installation method of conventional outdoor LED large screens, steel structures are indispensable. This is because the outdoor environment is relatively harsh, and the display needs to be waterproof, dustproof, moisture-proof, and anti-corrosion. In addition, the LED display module must be waterproofed with glue, which leads to a large screen weight, and the weight of one square can reach about 85KG. For large screens, this places high demands on the load-bearing capacity of the installation site, especially when installing on columns. If the construction specifications are not strictly followed, there may be safety hazards. Here are some installation methods for LEDs.

A significant advantage of conventional outdoor LED displays is high brightness, but this also brings about the problem of light pollution. Some countries, especially some European countries, have issued policies to prohibit the installation of such displays. In my country, in new urban planning, the location approval of outdoor LED advertising screens is becoming increasingly difficult, and even some installed displays are facing demolition.

Innovation breakthrough: the rise of LED transparent screens

In order to solve the shortcomings of conventional outdoor LED displays, especially the problem of light pollution, LED transparent screens came into being. LED transparent displays are a new type of product, mainly used in glass curtain walls, window cabinets, special effects screens in large shopping malls, rental screens and other fields. Its main features include high light transmittance, good energy saving, easy installation and good heat dissipation. LED transparent screens are installed indoors, but the display effect can be viewed from outdoors. They are named because they are not waterproof and have high light transmittance. Here are ten questions about transparent LED window displays.

Although the price of LED transparent screens is relatively high, with the continuous development and popularization of technology, price reduction is an inevitable trend. This new type of display can not only fill the market gap, but also achieve high-quality display effects without affecting indoor light and vision.

Conclusion

The development history of outdoor LED displays shows how technological progress drives product evolution. From the initial direct-plug LED display, to the popularization of surface-mounted lamp beads, to the innovation of LED transparent screens, each technological breakthrough has brought about the improvement of display effects and the expansion of application scenarios. Although conventional outdoor LED displays face some challenges, the emergence of innovative products such as LED transparent screens has brought new possibilities to the market. With the further development of technology, outdoor LED displays will continue to play an important role in advertising, information dissemination and other fields to meet the ever-changing market needs.
