What Factors Should You Consider When Buy LED Screen?

A complete set of full color LED display mainly includes three parts, computer, control system and LED screen (including LED cabinet). Among them, computer and control system are of roughly the same brands used by various manufacturers in the industry , customers don’t need to worry about its quality. For LED screen, its components are numerous and complex, which is an important part that determines the quality of the LED display. In this part, the selection of light emitting components (LEDs), driving components and power supply components is particularly important.

1. LEDs

Full color LED display consists of thousands of light-emitting diodes (LEDs) in a regular arrangement. The light of these lamps is generated by the chips encapsulated inside. The size and type of the chips directly determine the brightness and color of the lamps. The inferior and counterfeit LED lamps have short lifespan, fast decay, inconsistent brightness, and large color difference, which have a serious impact for the effect and life of LED screen. Customers must know the lamp chip manufacturer, size and packaging epoxy resin used by the manufacturer and the supporting manufacturer of the bracket when purchasing LED screen. SRYLED mainly use KN-light, Kinglight and Nationstar LEDs to ensure good quality and long lifespan LED screen.

2. Drive Material

The design of the drive circuit greatly affects the effect and service life of LED screen. Reasonable PCB wiring is conducive to providing overall work performance, especially the uniform heat dissipation of the PCB, and EMI/EMC issues that need to be paid attention to when developing and designing. At the same time, a high reliability drive IC is of great help to the good operation of the entire circuit.

3. Power Supply

Switch power supply directly supplies power to the electronic components of LED display. Customers should consider whether the switching power supply are from a professional power supply manufacturer, and whether the switching power supply configured with LED screen meets the needs of the work. In order to save costs, many manufacturers don’t configure the number of power supplies according to actual needs, but let each switching power supply work at full load, even far exceeding the load capacity of the power supply, which is easy to damage the power supply, and LED screen is unstable. SRYLED mainly use G-energy and Meanwell power supply.

4. LED cabinet design

The importance of LED cabinet cannot be ignored. Almost all components are attached to the cabinet. In addition to the protection of the circuit board and the module, LED cabinet is also important for safety and stability of LED screen. Has a great impact, but also waterproof, dustproof and so on. In particular, the role of ventilation and heat dissipation determines the working environment temperature of each electronic component on the internal circuit, and the air convection system should be considered in the design.

In addition to considering the main components such as LED lamps and ICs, other components such as masks, colloids, wires, etc. are all aspects that need to be strictly inspected. For outdoor LED screens, the mask has a protective LED screen body, reflective, waterproof, dust-proof, UV-proof lamps Under the influence of long-term sun and rain and the surrounding environment, its protective ability will decline, and the inferior mask will even deform and completely lose its effect. The colloid filled in the module in the outdoor LED screen will gradually age under the irradiation of sunlight, rain and ultraviolet rays. After the characteristics of the colloid change, it will crack and fall off, causing the circuit board and LED to lose the imitation protective layer. Good colloids will have strong anti-oxidative aging ability, and cheap colloids will fail after a short period of use.

It is recommended that buyers and suppliers should carefully communicate the following points:

1. Tell manufactures your actual needs, budget and expected effects.

2. Explain in detail your project development needs and future planning, such as size, install place, install way etc., and require manufacturers to provide the best solution to ensure that the project meets your needs.

3. Different LED production process, screen assembly process, and installation technology experience will directly affect the construction period, cost, safety performance, display effect, lifespan and maintenance cost of the entire project. Don’t be greedy and find the cheapest product .

4. Know more about the supplier’s scale, strength, integrity, and after-sales service to avoid being deceived.
