Seeing that the press conference is about to start next month, the stage background is still empty? I saw that the naked 3D large screen in the atrium of other people's shopping malls was queued up every day, but I could not even rent a decent screen when I was doing my own activities? Don't worry! Let's talk about it today,​Where should I rent this LED electronic screen?​, how to avoid the deep pits in the quotation orders and pick out equipment that can be carried out and achieved results.

1. List of leasing channels

Looking for an LED screen is like a blind date, you have to first find out the details of the matchmaker:

• ​​Offline physical stores​​: The advantage is that you can touch the real machine, but be careful that some merchants use repaired second-hand screens to recharge, and rent them back and play the videos all with color blocks.
• ​Online service platform​: You can compare prices with a little bit of a phone, but you should stare at whether there are any real-life cases and don’t believe in those over-PS renderings
• ​​Direct procurement of industry exhibitions​​: The latest technology can be seen on occasions like Shenzhen Optical Expo, but be careful that the exhibits are not the same batch as the actual shipment

Last year, a music festival made a joke - the renter boasted about the P2.5 high-definition screen, and when he arrived at the scene, he found that he had a model label re-sticked with the P3.91 screen. Later it changed​True P2.5 screen with automatic brightness adjustment​​, the MVs broadcast under the sun at noon are clearly visible, and then the venue is saved.

2. Word game in parameters

Don’t be honest when looking at technical parameters, focus on these three items:

1. ​Point spacing tricks​：

   • At least P2.5 should be viewed within 5 meters indoors
   • Outdoor advertising screen is lower than P4, which means being a hooligan
   • The most tricky thing I have ever seen is to mark P3.91 as P3, and everyone's faces are mosaics from three meters away.

2. ​​Brightness trick​​：

   • Indoor 800-1200cd/m² is sufficient
   • Outdoors below 4000cd/m² are decorations
   • Test tips: Cover the upper half of the screen with your palm at 12 noon, and you can still see the content clearly to be considered as the standard

3. ​​Refresh rate trap​：

   • 1920Hz is the bottom line, so you won’t have water ripples when shooting videos
   • High-end screen can achieve 3840Hz, and the camera will not drag on the camera.
   • Self-test method: Turn on the slow motion mode of the phone to shoot the screen, if there is black bar flashing, it will not be enough to brush it

To give a real case: An interactive floor tiles rented in a shopping mall for the anniversary celebration, the contract did not contain the protection level, but the naughty child sprinkled a cup of milk tea and shorted it directly. Later it changed​IP65 waterproof + riot glass maskThe model is fine for naughty kids to jump around for three days.

3. Nine series in the quotation

These routines are more exciting than palace dramas:

• ​Modular Games​: It is agreed that the brand new national star lamp beads are actually mixed with old products from different batches
• ​Time Magic​: Is the installation and debugging time also considered the rental period? Regular operations should start timing from the official activation
• ​Invisible package​: The low price of 200 yuan/square meter is attractive, and transportation insurance, commissioning fees, and even "air detection fees" are generated when signing the contract.

A certain car company suffered a secret loss at the press conference - the contract said "high-definition display" and found that it only supports 1080P when broadcasting 4K promotional videos. The temporary emergency equipment replacement cost 110,000 more, and this lesson tells us​It must be written in black and white to support HDR10+ and 4K@60Hz​​。

4. After-sales guarantee life and death line

A 24-hour response is not just a joke:

• ​​Remote diagnosis should be standard​: The screen suddenly blackened at the New Year's Eve party, and the video guidance completed hot plugging in 10 minutes
• ​​A sufficient spare parts library​: The heavy rain caused 16 modules to get water in? 30% spare modules are replaced in 20 minutes
• ​​Operation manual must not be missing​: Some hotel electricians can't even turn on the power supply sequencer, so they just unplug the plug and burn the control card

Let me tell you a thrilling story: I suddenly encountered a mudslide in the mountain music festival, and the equipment car was trapped halfway. Reliable service providers directly adjusted the helicopter airdrop technician and lit up the large screen two hours before the opening. This​I would rather lose money than lose my signatureThe ruthlessness is really reliable.

Editor's opinion

After eight years of execution of the event, I said something heart-wrenching:​Choose a renter is like choosing a marriage partner​, the appearance (display effect) should be online, the property (equipment inventory) should be thick, and the temper (after-sales service) should be better. Before signing the contract next time, remember to bring a knowledgeable person to the warehouse - touch whether the seams of the box are flat, and try to quickly disassemble and assemble. It is best to ask the technician to disassemble a module in person to see the lamp bead brand. Remember, the quality of merchants who dare to let you randomly inspect equipment is definitely not much worse!
