Interpretation of three stages of LED display development

The competition in the LED display market is fierce. If enterprises want to take root and stabilize their position, the effective way is to concentrate on improving the market share of the market segments, and at the same time increase investment in technological transformation and scientific research and development, it is an effective way to persist in building channel brands and seek long-term and sustainable development of enterprises. LED display screen is the visual product of security system terminal. In recent years, the prosperity of the security market has attracted many enterprises to test the water one after another. More and more enterprises have begun to join the camp of LED display screens. Domestic veteran manufacturers have also stepped into the liquid crystal production line one by one. the appearance of ultra-thin, no radiation, no flicker, low energy consumption, light and beautiful LED display screen has broken the original single pattern. LED display screen has been favored by the technology market from the past. up to now, the mainstream of application has ushered in a new era in the field of LED display screen. In the past few years, the domestic LED display industry has ushered in a small golden period of rapid development. The annual growth rate of the industry's profits was as high as 30% to 40%. A number of well-known trademark enterprises have emerged and a number of brand enterprises have been cultivated. Technology research and development plays an indispensable role in the development of well-known domestic LED display enterprises. On the other hand, the research and development of technology enables these enterprises to gain a higher market share even if the whole industry is not prosperous. Therefore, technology is the core competitiveness of this industry. The development trend of LED display technology confirms the development and changes of LED display industry. The development of LED display screen has gone through three stages. Due to the limitation of physical structure of CRT monitor and the weakness of electromagnetic radiation, people began to look for updated security Display Media LED display screen. The security LED display screen has no radiation, full plane, no flicker, no distortion, large visual area, small volume and weight, and strong anti-interference capability. however, the defects such as too small viewing angle, insufficient brightness and contrast have also made considerable progress with the improvement of technology. The early domestic LED display market was once occupied by foreign brands, which was extremely expensive and costly and was rarely used in security monitoring projects. Now TCL, Chuangwei Qunxin, Taipower and other companies have launched new LED display products. At a time when the domestic monitor market is undergoing analog upgrading to digital upgrading, LED display screen will continue to seize the market quickly with the advantages of high resolution, high contrast, high brightness, long service life, energy saving and environmental protection, wide color range, convenient installation, etc, the LED display market will be the driving force for vigorous development in the next few years. LED display screen has experienced the following three stages of development :(1) The growth and formation of LED display screen before 1990. On the one hand, due to the limitation of LED materials and devices, the application field of LED display screen has not been widely developed. On the other hand, display screen control technology is basically a communication control mode, which objectively affects the display effect. During this period, the LED display screen was widely used in foreign countries, but rarely in China. The products were mainly red and green primary colors, the control mode was communication control, and the gray level was single point 4-level gray adjustment. the cost of the product is relatively high. (2)1990- In 1995, this stage was a period of rapid development of LED display screens. Entering the 1990s S, the information industry has been growing at a high speed, and various fields of information technology have been making continuous breakthroughs. LED display screens have also made continuous new achievements in LED materials and control technology. Blue LED chip was successfully developed and full color LED display screen entered the market; With the technological development in the field of electronic computers and microelectronics, video control technology has emerged in the field of display screen control technology. The gray scale of the display screen has realized 16 gray scale and 64 gray scale, the dynamic display effect of the display screen is greatly improved. At this stage, the development speed of LED display screen in our country is very fast, from the initial short-selling enterprises with an annual output value of tens of millions yuan to dozens of enterprises with an annual output value of hundreds of millions yuan. the application fields of the products involve many fields such as financial securities, sports, airports, railways, stations, highway transportation, commercial advertisements, post and telecommunications, etc. in particular, the development of the Securities and stock industry in 1993 has LED to a substantial growth in the LED display market. The mainstream product situation of LED display screen in the field of flat panel display has basically taken shape, and LED display screen industry has become an emerging high-tech industry. (3) Since 1995, the development of LED display screen has entered a period of overall steady improvement and adjustment and perfection of industrial pattern. Since 1995, the competition within the LED display screen industry has intensified, forming many small and medium-sized enterprises. The product price has dropped sharply and the application field has been broader. A series of new problems have emerged in the quality and standardization of products, relevant departments have attached importance to the development of LED display screens and have properly standardized and guided them. At present, the work in this area is gradually deepening.
