LED display power supply is an important part of LED display, its stability determines the color and effect of LED display
With the popularization of information technology, visualization, intelligence, 3D, VR, AR and other technologies, the cross-border integration with LED display has become a reality. At the same time, with the continuous development of LED chip materials, drive IC, control, packaging and other technologies, LED display will inevitably make a breakthrough in the direction of high density, lightweight, energy saving and personalization. Therefore, more and more requirements are put forward for the supporting power supply The higher the demand. The following Chuanglian power supply answers the related questions about the development status and future trend of LED display power supply in detail!
Q1: LED display has entered the era of “small spacing”. What impact will it have on the development of power supply? What are the main stages of the development of LED display power supply?
A: At present, the small spacing products in the market have begun to enter the stage of mass production, especially the hot cob packaging technology, coupled with the continuous development of LED chip materials, driving IC, control and other technologies, it is even more intensified the development and popularization of small spacing technology. It is expected that in the future, small spacing will continue to usher in explosive growth. The following is the innovation of power supply products.
Ultra thin, light and small, customized and intelligent will be the development direction of small space power supply. Chuanglian power has invested a lot of manpower and material resources in this aspect to make full preparation for the coming outbreak of small space market.
Q2: what is the development trend of mini led and micro led in the future display applications?
A: With the rapid development of the current small space display market and the increasingly high requirements for display technology, the advantages of miniled and microled technology in the display field are increasingly difficult to be ignored. Chuanglian power believes that miniled display and microled will be higher-order display technology, and also the development trend of display application in the future. The rise of miniled and microled is an important field for the future development of LED. At present, miniled has mass production capacity, microled is the focus of most manufacturers’ research and development, and it is expected that there will be huge development space in the future.
Miniled and microled display have the characteristics of no seam, high brightness and no reflection image. With the advantages of clarity, image quality, thickness and reaction speed, miniled and microled display have gradually switched from commercial level display to consumer level display. Moreover, downstream application enterprises are also vigorously promoting them. Once they are applied on a large scale, the prospect will be very broad. Compared with traditional LED display products, miniled and microled have a series of advantages such as cost, price, packaging, protection, transportation, installation and maintenance, which can solve the problems of traditional LED display. At present, the application of mini LED is still limited in the high-end market, while microled is still in the stage of small batch samples, and there are still technical bottlenecks to overcome.
Q3: with the development of mini led and micro LED technology, what impact will it have on the LED display industry? What are the challenges to the display power supply?
A: From the development of miniled and microled technology, it is not difficult to see that the cost problem is one of the biggest doubts and the most difficult problems in the popularization of miniled and microled, because the breakthrough of these technologies will face many problems such as supply chain, production process, R & D and innovation. Only by reducing the cost can it enter the mainstream consumer market. In addition, the development of miniled and microled technology will cause a new round of upsurge for the development of display power supply, and put forward higher requirements for the cooling performance, power, size requirements and response speed of power supply, which also means that the traditional LED display industry will face new challenges and opportunities.
The technology trend of ultra-thin, light and small, customized and intelligent LED power supply will be fatal to power supply manufacturers without technical reserves. Under multiple pressures, many display power supply enterprises may be difficult.
Q4: the process materials of LED display power supply largely determine the service life of the power supply. What is the current development trend of power supply materials?
A: The main factors that determine the service life of display power supply are electrolytic capacitor, IC, MOS tube, transformer and other key devices. With the increasingly strict environmental inspection of the national team, the suppliers of key components will be more and more concentrated, and the purchasing advantages of large-scale manufacturers will be more and more obvious. At present, there will be no big change in the electrical performance materials of key power supply. The places with big changes may appear in MOS transistor and IC chip, because the intelligent power supply will be the key development direction in the next few years.
Q5: for LED display screen users, energy saving and environmental protection is a very important indicator. What role can power enterprises play in this? How can led display power supply achieve better energy saving and environmental protection?
A: In the application of LED display products, power supply is a very key device. To produce more environmentally friendly and energy-saving power supply, energy saving and environmental protection is the goal of every power supply enterprise. The energy saving and environmental protection of power supply focus on the following aspects: environmental protection production line, environmental protection solder paste, environmental protection tin furnace, low voltage, with PFC circuit. At present, the control of the production process is relatively easy, but most display screen manufacturers choose products without PFC circuit based on cost control and maintaining market competitive advantage, which will virtually form loop interference to the power grid, which is very unfavorable to the whole power grid. However, the better phenomenon is that display screen manufacturers no longer blindly pursue brightness, but pay more attention to energy conservation and environmental protection, At present, large screen manufacturers generally start to use 4.2V, 4V, 3.8V or even 3.3V power supply scheme, which is a very good energy-saving scheme.
Chuanglian power supply series is an energy-saving and environmental protection led common negative screen power supply solution. It has the advantages of high efficiency, energy saving, safety protection, good heat dissipation, small electromagnetic interference and high reliability. The common cathode products adopt precise power supply control technology to precisely allocate different voltages for LED and drive circuit, so that the power consumption of the products is more energy-saving than that of similar products on the market! The common cathode LED driving mode can accurately control the voltage, reduce the power consumption and the heat value, so that the wavelength of LED does not drift under continuous operation, and the real color can be displayed stably! In terms of energy consumption, it can also significantly reduce the temperature rise of the system, effectively reduce the LED damage probability, improve the stability and reliability of the whole display system, and greatly extend the system life.
