LED display heating temperature is too high what damage

Nov 22,2023

Xiamen LED display is an advertising display device with audio and video functions. LED display is gradually replacing canvas advertising and light box advertising with good advertising effects. LED display is very popular because of the vivid picture, then you know what damage LED display heating temperature is too high? This will lead to color correction failure, LED at low temperature and high temperature, the wavelength drift is relatively large. 2. Output brightness reduction: According to understanding, every temperature change in degrees Celsius leads to a 1% change in output brightness. It is worth mentioning that the red light is significantly affected, and its brightness will be reduced by nearly 2/3. Relatively speaking, the temperature influence of blue light and green light brightness is not so strong. When the temperature rises, the brightness emitted by LEDs of different colors is different. 3, leading to shortened LED life: According to a laboratory data in a country, the junction temperature increased from 63C to 74C, and the LED life was reduced from 36000 hours to 16000 hours. 4, the system cost: too many heat dissipation components are damaged, once broken must be reconfigured, thus increasing the system cost. Increase the cost of use: because of the excessive consumption of energy, the cost of use will rise. Xiamen LED display has a wide range of applications, will appear in shopping malls and central areas, in the subway, high-speed rail and underground parking lot we can see its figure, in these occasions the use of LED display can fully attract the attention of the audience in a small space to achieve a good communication effect.

The news headline here is whether the brighter the LED display, the better!

Oct 24,2023

Is the brightness of the LED display getting better and better? Xiaobian here can clearly tell you that this is not the case. I think people in the industry should know that LED display is mainly composed of diodes. Because of its energy saving and high brightness, LED products are very popular in the display industry. When many LED display manufacturers introduce to customers, most of them will say that the higher the brightness, the better the quality. Is that really the case? The little editor takes you to uncover the truth.

LED special-shaped screen has the characteristics of irregular

Apr 05,2024

The special-shaped LED screen is a special-shaped LED display screen transformed into a special-shaped LED display screen on the basis of the LED display screen. It is different from the rectangular and planar shape of the regular LED display screen. It has different shapes, including arcs, curved surfaces, quadrangular hexahedrons, letters and other irregular shapes. To distinguish the shape, LED shaped screen roughly the following categories: 1. LED spherical screen LED spherical screen 360 ° full visual angle, all-round video playback, any angle can feel good visual effect, no plane viewing angle problem. At the same time, it can also directly project spherical objects such as the earth and football to the display screen according to the needs, which makes people feel vivid and is widely used in museums, science and technology museums and exhibition halls.

LED electronic display in the domestic market in the end how

Nov 22,2023

With the continuous improvement of technical indicators such as point spacing, stability, grayscale, and brightness, LED displays are also showing their unique advantages in more and more fields. With the continuous improvement of technical indicators such as point spacing, stability, grayscale, brightness, etc., LED displays are also showing their unique advantages in more and more fields. According to the current market development, LED displays will still be in For a long time to maintain a strong growth space, but it will also encounter problems in the development of all industries. LED display barriers 1. R & D and technical barriers LED display and lighting industry as a high-tech industry, involving optics, thermal, materials science, electronics, computer, software, automation, mechanical engineering, decorative arts and other disciplines, and need to be integrated system application of the above disciplines, with high technical barriers. At the same time, because LED products are mostly customized and personalized production, they have high technical requirements for production technology, quality control level and stability. Problems in any part of production may affect the quality, life and performance of the product. 2. Financial barriers LED display and lighting industry is a capital-intensive industry, the degree of automation is not high small enterprises can not guarantee product quality and production capacity, so only in the low-end market for simple price competition. In the current market environment, to participate in bidding to undertake large-scale projects, we must invest in advanced machinery and equipment, improve production capacity and technical level. In addition, the industry's common production model is production plus engineering installation, engineering installation links lead to long capital return cycle, low asset turnover efficiency, high capital scale requirements. LED display is good 1. National industrial policy support A number of industrial policies put forward by the State Council, the Ministry of Science and Technology, the National Development and Reform Commission and local governments have played an important role in promoting the development of the entire LED industry and the optimization and upgrading of the industrial structure. Under the background of industrial policy support, the industrial scale is expanding day by day, and the industrial chain is becoming more and more complete, which creates good conditions for enterprises in the industry to improve their competitive strength and participate in international competition. A number of backbone enterprises with independent intellectual property rights and core competitiveness are expected to emerge in China. 2, the product application range is wide, the market prospect is broad Various LED applications are in the ascendant. Domestic LEDs have gradually formed hundreds of LED application products such as instructions, signals and displays, and backlight lighting. They are widely used in landscape decorative lighting, large-screen displays, traffic lights, home appliance digital displays and indicators, car lights, Mobile phones, digital cameras, computers, LCD TV backlights and other fields. With the development of technology, LED also appeared new application direction, such as aerospace, medical, agricultural and other fields. The steady growth of the market share of various LED applications and the continuous emergence and development of emerging applications have created a good market space for the development of the LED industry.
