"I want to make an LED display but can't find a reliable manufacturer?" I have heard this question less than ten times. Let’s talk about it today. Looking at a simple luminous board, where should we find experts to make it and how to avoid pitfalls.

1.​First figure out what you are going to do​​

Don't look at the luminous screen,​Usage scenarios determine the production direction​：

• ​​Advertising category​: The big guy in the exterior wall of the mall has to withstand the sun and rain.​​The brightness must be 5000cd/m²​​, also requires intelligent light sensing adjustment. There is a typical case - a curved screen in a business district in Southeast Asia. It hasn't changed the lamp beads for five years, and the secret is using military-grade waterproof glue.
• ​Stage performance category​: The focus of the concert floor tiles screen is to play with special effects.1920Hz refresh rateand​≤3ms response speed​. A certain music festival suffered a loss, and the screen shots were all full of shadows, and the live barrage was always "mosaic stage beauty".
• ​​Sports events​: The court fence screen is resistant to collision and fabrication.​IP65 protection​It is the bottom line, the box must be made of aviation aluminum. Some venues have tried ordinary boxes, and players hit them and directly concave a hole. Now they have changed to magnesium and zinc alloys.

II.​Don't compromise on core technical parameters​

To choose a manufacturer, you have to learn to look at the hard indicators.​These data hide real kung fu​​：

1. ​Pixel spacingDetermine the clarity:

   Viewing distance	Recommended spacing	Applicable scenarios
   Within 3 meters	P2.5-P3	Shopping mall windows
   5-10 meters	P4-P6	Stadium fence
   15 meters+	P8-P10	Highway billboard

2. ​​Grayscale​Influence the texture of the picture. A museum project fell into trouble - the ordinary screen shows the details of antiques and are replaced by ​16bit high gray screenLater, even the rust spots of bronze ware could be seen clearly.

3. ​​Protection performance​Require actual testing. A beach project requires that the screen be soaked for half an hour and still be able to work. The manufacturer directly took the team to the beach for on-site testing, and then he won the order.

III.​Service network is more important than price​​

Reliable manufacturers have these​Invisible Strength​：

• ​24-hour response​Not empty talk. A Tokyo stadium flashed in the middle of the night, and the engineer guided local workers to do it for two hours. The game was as usual the next day.
• ​​Full process service​It must be implemented in the contract. From measuring and installing angle to debug color consistency, professional teams will use​​Spectroscopy analyzer​​Calibration to ensure that the screen is not distorted when viewed 20 meters away.
• ​Customization capability​See the true chapter. For example, the special-shaped timing screen used in an international event requires integrating wind speed sensors and AR special effects. Manufacturers without two brushes cannot handle this job at all.

IV.​The landing case hides hard power​

Depend on the manufacturer's level,​Practical projects​The best explanation:

• A Korean song program usedTransparent interactive screen​, artists can activate particle effects when touching, this​Infrared sensing + AR superposition​​Technology, without ten years of R&D experience, can’t be used.
• Singapore Airport​Curve guide screen​, the arc error is controlled within 0.1mm, and three-dimensional laser positioning is used during installation, which is more accurate than building blocks.
• Japanese yakuza dance base​Floor tiles splicing screen​, support 200 people to jump at the same time, and have not changed the module in three years, so the durability is indeed good.

If you ask me, finding an LED manufacturer is like finding a partner—​​The parameters are resumes, cases are love history, and services are character​. Those "all-round players" who can handle difficult orders and can be called upon at any time are the ones worthy of entrusting. Next time you choose a manufacturer, you might as well take these three mirrors to keep your "true emperor"!
