The power supply voltage of the LED display is usually based on its specific model and specifications, but in general, the operating voltage of the common LED display is between 5V and 24V. Next, the LCF editor will give you the knowledge of LED display power voltage in detail.


First, why do LED displays need a specific power supply voltage?


An LED display is made up of a number of leds (light-emitting diodes), each with its specific forward voltage (Vf) requirements. When a current passes through this forward voltage, the LED lights up. If the voltage is too low, the LED may not light properly; If the voltage is too high, it may cause the LED to overheat or even burn. Therefore, in order to ensure the normal operation and life of the LED display, it is necessary to provide a stable and suitable power supply voltage.


Second, what is the common LED display power supply voltage?


Small LED modules and bar screens: These products usually use 5V or 12V DC power supply. For example, some indoor small LED modules or monochrome bar screens may only require 5V voltage.

Medium and large LED displays: For medium and large LED displays, such as those on outdoor billboards or large stadiums, higher voltages, such as 24V, may be required. These displays typically consist of many LED modules, each of which requires an independent power supply.

Customized products: For customized LED displays, the power supply voltage may be determined according to the specific needs and design of the customer.

Third, how to choose the right power supply for the LED display?


Determine the power and current requirements of the display: When selecting a power supply, first understand the total power and current requirements of the LED display. This can usually be found in the product manual or technical specification sheet.

Choose a power supply with sufficient output capacity: The output capacity of the power supply (usually in watts or amps) should be greater than or equal to the demand of the display. If the output capacity of the power supply is insufficient, the display may have uneven brightness or not work properly.

Consider the efficiency and thermal performance of the power supply: An efficient power supply reduces energy waste and reduces heat generation. When selecting a power supply, attention should be paid to its efficiency and heat dissipation performance to ensure that it remains stable during a long working period.

Choose a power supply with overcurrent, overvoltage and short circuit protection: In order to protect the LED display from potential damage such as current, voltage fluctuations or short circuit, you should choose a power supply with the corresponding protection function. These protection features ensure that the current is cut off in the event of an anomaly to prevent damage to the display.

Consider the reliability and life of the power supply: The reliability and life of the power supply is essential to ensure the long-term stable operation of the LED display. When choosing a power supply, you should choose products that are well-known brands, certified and have a good reputation.

Pay attention to the interface type and compatibility of the power supply: When selecting the power supply, ensure that its interface type and compatibility match the LED display. Different displays may require different types of power interfaces, such as plug, terminal, etc. When selecting the power supply, ensure that it is consistent with the interface type of the display screen and has good compatibility.


In short, the power supply voltage of the LED display is usually between 5V and 24V, depending on its model and specifications. When choosing the right power supply, you should consider the power and current requirements of the display, the output capacity of the power supply, efficiency and heat dissipation performance, protection functions, reliability and life, and interface type and compatibility.
