The transition from CRT displays to liquid crystal displays has revolutionized both product size and display technology. LCD monitors have evolved to this day and have undergone many changes. From universal screen ratio to widescreen ratio, from CCFL backlight to LED backlight, from TN panel to low-cost wide viewing angle panel, from 2D display to 3D display, from ordinary display to touch display, etc., these changes also make LCD monitors In the past few years, I have been moving forward. The development of the display industry is in urgent need of technical updates, and the future development of LED light sources will greatly replace CCFL light sources.
Analysis of the competitive development direction of LED display enterprises
In recent years, the LED industry has entered a period of rapid development. The LED display field has reached a peak demand period. Where is the demand market for LED display in the future? Where are the development directions of enterprises? These problems are increasingly competing in the LED industry today. In a fierce environment, it is the most important issue for our LED display companies.
With the advancement of social science and technology and the development of outdoor advertising, people's demands for outdoor media are getting higher and higher. Traditional outdoor signs such as street signs, light boxes, single columns, neon lights, etc., can no longer meet the needs of the audience. As a result, the LEDs began to surface. The LED full-color display is the perfect combination of technology and media. It can fully utilize this concept and become the future development trend of outdoor media.
With the good advertising efficiency brought by the new LED display, it is gradually recognized by more and more outdoor media and advertisers, which has caused a lot of market demand. The huge business opportunities in the LED display market are attracting capital attention. As a revolutionary wave of advertising, LED advertising screens and LED large screens are developing rapidly with strong momentum. The LED large screen market has formed a new development trend.
In addition, the impact of major events and events, such as the 2008 Beijing Olympics reel, the Shanghai World Expo to the exciting Universiade, the passionate World Cup, and the inspiring Guangzhou Asian Games, these events not only make the LED display shine, but also let the outdoors Advertising has also become more and more exciting.
Moreover, the overall environment is relatively good. In 2011, China's economic performance was good, and the outdoor advertising market showed a steady growth momentum, maintaining a steady and rapid growth. In a good climate, the outdoor advertising market has also shown rapid growth. In the first 10 months of this year, the total amount of outdoor advertising reached 39.5 billion yuan, which exceeded the total amount of the previous year's total. 13. Excluding the collection range and the price changes of the publication, the net value of outdoor advertising in the first 11 months was higher than last year. It is estimated that the amount of outdoor advertising this year is expected to reach 43 billion yuan, an increase of about 20 years.
Such a good development market and environment, LED display companies want to stand out from the crowd, not the price, but the competition between brand value, customer management and professional quality. Therefore, LED display manufacturers should pay more attention to the company's own brand building, focusing on technological innovation, quality and customer relations.
Industry Status: Display urgently needs technical updates
Let us first summarize some of the existing display technologies. TN-type panels and wide viewing angle panels are definitely the most common display technologies in our daily life, and of course the most popular LED backlights. In some high-end markets, polarized and shuttered 3D display technology, 25601440 and 25601600 high-resolution technology, touch display technology, etc., although these technologies are present in the market, we rarely see end consumers Choose monitor products that cover these technologies. The main factor is that these technologies still have a lot of restrictions in daily applications, perhaps the limitations of entertainment applications, perhaps the limitations of the user's host hardware, etc., so consumers can not be fully satisfied in the process of use.
For today's monitors, in addition to the largest shipment of small-size TN panel displays, large-scale high-profile products such as 27-inch products, low-cost wide-angle viewing products, etc. have also been supported by users. . The current display market, especially the civilian-grade market, can be said to have been highly developed and the market has gradually saturated.
Therefore, for the current display market, the stimulation of new technologies, or the continued improvement and upgrade of existing technologies, helps users to apply these display products covering more technologies in a simpler way. This will enable the display market to continue to move forward.
2013 commercial display trends
CCFL light source will gradually withdraw from the market LED light source to replace
LED displays actually refer to liquid crystal LCD displays that use LEDs as a backlight. The LCD display device itself does not actually emit light, and it is necessary to use a backlight to achieve the display function. Therefore, the performance of the backlight directly affects the LCD display quality.
The backlight used in the conventional liquid crystal display is a cold cathode fluorescent lamp (ColdCathode Fluorescent Lamp), referred to as CCFL. Because CCFL has small lamp tube, simple structure, small surface temperature rise, high surface brightness, and easy processing into various shapes (straight tube shape, L shape, U shape, ring shape, etc.), long service life, good color rendering, and light emission. Uniform and other advantages, is the most widely used LCD backlight in recent years.
However, with the development, CCFL has also exposed some shortcomings, such as narrow color gamut, low energy efficiency, high power consumption, environmental pollution, etc., so people are always looking for alternative technologies and products, and in this process, LED backlight technology Products have been included in the selection of people.
Compared with CCFL backlights, LED backlights have five major advantages: First, the ultra-wide color gamut can reach the 105NTSE color gamut, so the color is more vivid. Second, the ultra-thin appearance, the thinnest reaches 1.99 cm, more fashionable. Third, energy saving and environmental protection, energy consumption is lower than cold cathode backlight 52, and there is no mercury pollution of cold cathode tubes. Fourth, long life, reaching nearly 100,000 hours, can be used for 27 years if you open 10 hours a day. Five, can achieve 100000:1 ultra-high contrast, higher definition.
In the era of low-carbon, environmental protection has become one of the most important indicators of electronic products, the use of LED backlights has undoubtedly become the first choice of many display manufacturers.
In 2012, with the large-scale release of LED production capacity, the product price was close to CCFL, and with its excellent energy saving and long-life characteristics, it was highly praised by manufacturers in the commercial display product line. In the product lines of Samsung, Sharp, LG, and NEC giants, we have seen that LED backlights have transitioned from gimmicks to real combat competitions. CCFL will fade out of the market, LED light source must be the mainstream direction of future products, this industry has already reached a consensus.
