Interpretation of the three stages of LED display development
The LED display market is highly competitive. The most effective way for enterprises to take root and stabilize their position is to concentrate on increasing the market share of the market, and increase investment in technological transformation and scientific research and development. A brand that seeks long-term and sustainable development of the company is an effective method. The LED display is the visual product of the security system terminal. In recent years, the security market has prospered unprecedentedly, attracting many companies to test the water. More and more enterprises have begun to join the large camp of LED displays. Domestically established manufacturers have also stepped into the LCD production line, ultra-thin, no radiation. The emergence of LED display without flicker, low energy consumption, light and beautiful, broke the original single pattern, LED display has been favored from the high-end market in the past, and nowadays the application mainstream, LED display field ushered in A new era. A few years ago, the domestic LED display industry once ushered in a small golden period of rapid development. The annual growth rate of industry profits was as high as 30% to 40%. A number of well-known trademark enterprises emerged, and a number of brand enterprises were also cultivated. Technology research and development plays an indispensable role in the development of domestic LED display companies. In turn, the research and development of technology allows these companies to achieve a high market share in the market under the circumstance of the industry. Therefore, technology is the core competitiveness of this industry. The development trend of LED display technology confirms the development and changes of the LED display industry. The development of LED display has gone through three stages. Due to the limitations of the physical structure of CRT monitors and the weakness of electromagnetic radiation, people began to look for updated security display media LED displays. Security LED display has no radiation, full plane, no flicker, no distortion, large visible area, small volume and weight, strong anti-interference ability, and the view angle is too small, the brightness and contrast are not big enough, etc. Considerable progress. The early domestic LED display market was once occupied by foreign brands, the price is particularly expensive, the cost is too high, and it is rarely used in security monitoring projects. Today, TCL, Skyworth Qunxin, Taipower and other companies have launched new LED display products. In the current domestic monitor market is undergoing analog upgrades to digital upgrades, LED displays will continue to be fast with high resolution, high contrast, high brightness, long life, energy saving, wide color range, and easy installation. To seize the market, the LED display market will gain the source of vigorous development in the next few years. LED display has experienced three stages of development: (1) The growth period of LED display before 1990. On the one hand, due to the limitation of LED material devices, the application field of LED display screens has not been widely developed. On the other hand, display screen control technology is basically a communication control method, which objectively affects the display effect. The LED display in this period is widely used in foreign countries. There are few domestic products. The products are mainly red and green. The control method is communication control. The gray level is single point and 4 level gray, and the cost of the product is relatively high. (2) In 1990-1995, this stage was a period of rapid development of LED displays. In the 1990s, the global information industry grew at a high speed, and information technology continued to break through in various fields. LED displays have also seen new results in LED materials and control technologies. The development of blue LED chips has been successful, and full-color LED displays have entered the market. In the field of electronic computers and microelectronics, video control technology has appeared in the field of display control technology. The gray level of display screens is 16 gray levels and 64 levels. Grayscale graying, the dynamic display effect of the display is greatly improved. At this stage, the development of LED display screens in China is very fast. From the initial few enterprises, the annual output value of tens of millions of yuan to dozens of enterprises, the annual output value is several hundred million yuan. The product application fields involve financial securities, sports and airports. , railways, stations, road traffic, commercial advertising, postal and telecommunications and many other fields, especially the development of the securities stock industry in 1993 has led to a substantial increase in the LED display market. The mainstream product situation of LED display in the field of flat panel display has basically taken shape, and the LED display industry has become an emerging high-tech industry. (3) Since 1995, the development of LED display has entered a period of overall improvement and improvement of the industrial structure. Since 1995, the internal competition of the LED display industry has intensified, and many small and medium-sized enterprises have been formed. The prices of products have fallen sharply, the application fields are broader, and a series of new problems have appeared in the quality and standardization of the products. The development has been paid attention to and has been properly regulated and guided. At present, the work in this area is gradually deepening.
