When the LED display customer chooses the power supply, the reason why the low output voltage and high current products (such as 5V/60A) are used is because the working voltage of the LED lamp bead is low, and the working voltage of the general LED lamp bead is 2.8~ 3.3V; red is 1.8~2.2V; blue is 3.0~3.2V; green is 2.9~3.1V; yellow is 1.8~2.0V, so display manufacturers will choose 5V when designing standard power supply Mainly powered.
However, with the continuous development and innovation of LED components, the efficiency of driver ICs is constantly improving. In the future, the power of LED displays will be converted to 4.5V/4.2V, and a new generation of RSP-200/320/ will be developed. At 500 o'clock, the development trend of the LED display industry has been expected, and many customers have to worry about the need to modify the voltage in the past. Therefore, a new generation of commonly used voltages such as 2.5V/3.3V/4V ​​has been planned as a standard. Product series, and the establishment of standard stocks, greatly reducing the troubles of LED display customer selection and modification.
With the rise of the rental LED display market, rental display screens have been widely used in hotels, booths, KTV\videos due to their small spacing, light weight, thin structure, hoisting and quick disassembly/handling/installation. In conferences and other fields, the specifications of small-pitch LED displays P1.9 and P1.6 have officially become the mainstream of the market, and P2.5 has gradually become more conventional. As the technology of small-pitch display screens matures, its application range will be more extensive; The small pitch and rental display customers have less need for power installation space and volume, can meet the customer's design requirements for size and height, and quickly become another choice for LED display customers on high quality standard power supply.
In addition, LED display screens often cause malfunctions due to factors such as pollution, looseness, vibration, humidity, and environmental temperature changes in their special application environment and use. The power supply is the heart of the LED display, and the display customer is on the power supply. The reliability requirements are getting higher and higher. Due to the unpredictable changes in the installation environment, it is recommended to select products with moisture protection as far as possible for outdoor fixed installation LED displays.
