Hey! The day before yesterday, an old man who opened a gym called me: "The advertising screen I just installed was black. What corner is hidden in this broken button? " I have a say in this matter! Today I will take you to play a "treasure hunting game". After reading this article, you will be even more sharp-eyed than the aunt who is looking for special price tags in supermarkets!

1. Buttons are not masters of hide and seek

Let me tell you a big truth first:​​LED screen buttons really didn't play with you​​! There are three common places to hide:

• ​​The bottom right border of the screen​​(Eight out of ten units are here, the same routine as the mobile phone power button)
• ​​Back panel maintenance port​​(Some waterproof designs will hide the buttons to protect the lid)
• ​​Remote control shortcut keys​​(The physical button cannot be found? Try the remote control menu key)

I encountered a funny thing last month. The shopping mall security guard touched the screen border, but guess what? The manufacturer designs the buttons as​ ​Breathing lamp style​​, light up with a touch! So,​ ​Don't rush to curse, maybe it's under your nose​​。

2. Different models and positions are very different

This is like looking for mobile phone interfaces of different brands, depending on the specific style:

1. ​​Outdoor advertising screen​​: The buttons are mostly in the grooves of the side aluminum frame (rainproof design)
2. ​​Rental screen​​: Basically it is concentrated on the inside of the quick disassembly and assembly handle
3. ​​Transparent screen​​: Ninety percent hidden at the bottom frosted border joint
4. ​​Floor tiles screen​​: The tricky design may be in the back maintenance warehouse

I remember that I adjusted a batch of floor tiles screens for the car show last year, and the showman looked for buttons on the floor for half an hour. Later I found out that the people used it​ ​NFC sensing start​​, you can wake up by sticking it on your phone! So now trendy designs have long been no longer limited to physical buttons.

3. Guide to self-rescue in emergencies

If you really can’t find the button, don’t panic. Try these three tricks:

• ​​Remote control blind fuck​​: Press and hold "menu + confirm button" for 5 seconds to restart
• ​​Mobile APP takes over​​: Now the new screen can basically be wirelessly connected and controlled
• ​​Power-off method​​: Turn off the switch directly and wait for 10 seconds before turning on (simple and crude but effective)

There was a hot pot restaurant who dealt with black screen faults and the boss couldn't find the buttons. As a result, the technical guy directly asked Lian's hot spot to adjust it with his mobile phone. So,​ ​Now, you have to keep up with the times when playing with LED screens and can't hold on to physical buttons.​​。

4. Check out the anti-lost strategy here

Anyone who has suffered losses knows that prevention is more important than remedy:

• ​​Fluorescent stickers​​(You can see it in the toilet at night)
• ​​Take photos and archive them​​(The first time you take a photo after installation)
• ​​Want a route map​​(Regular manufacturers will give operation diagrams)
• ​​Regular inspection​​(Check the button sensitivity every month)

I met a girl who was a beautiful girl in the mall and was very clever. Every time I installed a new screen, I asked the engineer to put a little yellow duck sticker on the button position. This method looks naive, but there is no trouble of not being able to find buttons.

5. The screen selection depends on the control design

After years of hard work, I sincerely suggest:

• ​​Physical + Virtual Dual Control​​The most reliable screen (be prepared to avoid blindly)
• ​​With emergency wake-up function​​Priority (black screen can also be used blindly)
• ​​The operation logic should be simple​​(The third-level menu or above are all anti-human)

I've recently seen a new trendy design​​Fingerprint recognition module​​Integrated into the keypad. Not only can it operate physically, but it can also set different fingerprints to correspond to different modes. I will give you a full mark in this idea!

Say something heart-wrenching

If you ask me to tell me, finding buttons is like falling in love——​​Understand the other person's routine​​! I have seen too many people touch the screen border and don’t find the buttons. In fact, many high-end screens are now taking the "keying" route. Some outdoor advertising screens are just used​ ​Voice wake-up​​, shouting "Start" is faster than finding a button.

I think manufacturers should learn automotive design and​​Emergency Physical Buttons​​Make it in bright red and put it in a prominent position. After all, at critical moments, it is the most reassuring button that can be touched. Remember, a good screen depends on hardware and seventy-point design. Finding a manufacturer that understands user experience is better than anything else!
