 - LED display technology evolution

LED’s birth

In 1923, LED was born. During lossen. When O. developed LEDs, he discovered that p-n junctions doped with impurities would emit light after being electrified.

Stage of formation

The LED display industry developed rapidly between 1990 and 1995. Full-color LED displays began to appear on the market. The production scale has increased from a few enterprises in the beginning, with an annual output value of tens of millions of yuan, to dozens of enterprises, with an annual output value of hundreds of millions of yuan. There are many fields in which products can be applied, including financial securities, sports, airports, railway stations, highway transportation, commercial advertising, and telecommunications.

Stage of popularization

The LED display industry underwent a period of overall improvement from 1996 to 2000, as well as adjustments and improvements to its industrial structure. Competition in the industry intensifies, product prices decrease, and the application field expands. Several new problems have emerged in the quality, standards, and other aspects of the products, promoting the further implementation of industry guidelines and norms. The overall scale of the industry reached 1.5 billion yuan by 2000.

Stage of promotion

From 2001 to 2005, China’s LED display industry developed steadily, and its overall scale increased. The industry scale reached about 4 billion yuan in 2005.

Stage of innovation

In 2006 to 2008, China’s LED display industry entered a new historical stage of development, and the scale of the industry increased rapidly. Overall, the industry grew by 44% in 2007. It was evident that the industry was experiencing intensive development. There has been continuous progress in the technology of the whole industry, and a standardization and technical system has been established for conventional products, with the ability to design and implement LED display engineering that is unique. LED display products have become a major manufacturer and application country in China.

Saving energy

In future life, energy conservation and environmental protection have always been on the agenda; LED display screens are very energy-efficient, and they have the following characteristics: high light efficiency, long life, easy to control, maintenance-free; it is a new generation of solid cold light source, with soft, bright, colorful, low loss, low energy consumption, and is a green and environmentally friendly product.

A lightweight design

As a result of the weight of the iron box itself and the steel structure, the overall weight was very heavy in the past. As a result, many floor buildings are difficult to support such heavy attachments, and they are difficult to disassemble and transport, making them much more expensive. The lightweight box is therefore a trend that all manufacturers need to keep up with.

The patenting process

There is fierce competition in the LED industry. Every enterprise competes for market share, customers, and scale. Research and development of products is rarely a priority for enterprises. Patents are the best way to maintain technical competitiveness and reduce the risk of technology spillover.

Spacing is small

One of the hottest products has always been small spacing. Currently, the indoor small spacing has broken through a few points and the outdoor small spacing has also broken through P2. As technology advances, the spacing will become smaller and smaller.

An interactive experience

The ultimate trend in LED display development is human-screen interaction. What’s the reason? A smart LED display enhances the sense of intimacy and operating experience of the user in terms of products. It takes 8 minutes to understand how LED interactive tile screens work.

In the 21st century, intelligent LED displays are showing a trend of differentiation and diversification. The outdoor media market has also experienced changes in the era of smart city construction and big data interconnection. To truly address the general needs of users, achieve the universal intelligence of the product market, and finally win the recognition of the market, the research and development of intelligent LED display products needs more design and development for user-level operators.
