LED backlight display unique features in the field of security

With the in-depth development of security technology applications, display devices, which are important display terminals for video surveillance systems, are increasingly being valued by security applications. LED backlight LCD screen as a new role, also appeared on the stage of large-screen display equipment. The LCD liquid crystal display is a display screen composed of a thin film transistor and a special light pipe on its back. After adopting the LED as a backlight, it becomes an LED backlight liquid crystal display.

The emergence of LED backlight LCD screens, thanks to energy-saving emission reduction policies are gradually reaching the hearts of people and low-carbon era. Energy-efficient and efficient green display devices have become the mainstream of demand in the commercial display field in recent years, and energy conservation has become an important standard for green procurement by government departments. For display products, low power consumption, low harmful substances content and long service life will become key green indicators.

The so-called LED refers to LightEmittingDiode, which is the LED we often say. This product and its application are not available now. Its application can be seen everywhere in our real life, such as roadside billboards and household appliances. The various indicators and backlights on the phone keypad use LEDs as the light source. LED backlights have greatly promoted the development of LED backlights by virtue of mercury-free green environmental protection, regional dynamic control backlights, low-carbon energy saving, ultra-thin streamline appearance of display screens, and vivid display of high color reproduction.

Security requirements for monitoring display devices mainly include: high picture clarity and stable operation for a long time, because the industry has doubled the cost of electricity for civilian use, especially for users with multiple display screens. Consumption is a problem that must be considered. Energy-saving display is not only a response to environmental protection and low carbon, but also can save users a large amount of electricity bills and has considerable economic value. Therefore, the author believes that the LED backlight display will be very useful in the security industry. Broad prospects. In 2010, display industry giants have also promoted LED backlight display as a key product line, and Samsung, LG, NEC, TCL and other domestic and foreign manufacturers have been involved.

The advantages of LED backlight display can meet the needs of various application scenarios, and the development prospect is very broad. It is recognized as the most growth potential and the fastest growing LED application market. It has been widely used in the large-scale sports events such as the 2010 Shanghai World Expo and the Guangzhou Asian Games. It also shows that the LED display will be promoted on a large scale.

However, the LED backlight module is not without its disadvantages. Because more LEDs are used, it also causes temperature rise. Therefore, it is necessary to increase the cooling system and the sensor to solve this problem. Therefore, it is more in thickness than the product using CCFL backlight. thick.

Although LED backlight technology has many advantages, it also has difficult to avoid widespread application difficulties. First of all, products that use this new technology have no advantage in terms of price. Moreover, LED technology is in the hands of a few manufacturers. The popularity has brought difficulties, and finally it is the reason of the technology itself. LED backlight technology is not doing very well in terms of luminous efficiency, current control and heat dissipation. From the long-term trend, LED backlight technology will gradually become popular as a replacement technology product. With the rapid development of Samsung and LG's new panel technology, this large-area application in the security industry should be compared. It can be achieved soon.

The competition in the field of security display has gradually evolved from simple display performance indicators, and gradually developed towards humanization, intelligence and energy conservation. Energy conservation and environmental protection are a major development trend in the world, and future display products will gradually move toward green, low energy consumption and sustainable development. With the improvement of people's living standards, LED backlight display will be fully applied to the security monitoring industry.
