Alas, have you encountered this situation? The newly purchased LED display was tossed and turned and couldn't find the USB port, so anxious that I was sweating. Last week, a customer who opened a shopping mall complained to me: "I bought a display screen for a lot of money, and I searched for a USB flash drive for half an hour! "In fact, there is a lot of knowledge hidden in the location of this USB interface.

1. Why do you need to hide the USB port of the display?

Don’t underestimate the location design of this interface. There are many ways to go here. ​ ​Just like the charging port of a mobile phone must be dust-proof and water-proof​ ​, the interface layout of LED displays must be considered in three major elements:

• ​​Waterproof and dustproof requirements​ ​: The interface of the outdoor screen is usually hidden in the sealed compartment
• ​​Convenience of use​ ​: The rental screen should be designed on the side of the box for easy insertion and removal
• ​​Line tidyness​ ​: Fixed installation screen will concentrate the interface to the back trough area

To give a real example, the USB port of the floor tiled screen made for the exhibition center last year is hidden at the joints of the module and is covered with a waterproof glue plug. A beverage that does not affect trampling and can prevent spilling. Is this design thoughtful enough?

2. Comparison of interface positions in different scenarios (table presentation)

You have to save this comparison table and compare it directly next time you choose the device. For example, when making a store window screen, choose the style of the bottom bracket, which is convenient for updating content and prevents customers from accidentally touching it.

3. Three emergency measures when you can’t find the interface

Don’t panic! It is absolutely correct to follow these three steps:

1. ​​touch​ ​: Grab slowly along the display frame, pay attention to the protrusions or depressions
2. ​​look​ ​: Find square/trapezoidal opening with dustproof cover, size approximately 2cm×1cm
3. ​​check​ ​: Flip the manual and look at the structural diagram, focusing on the "signal input" chapter

The case that helped the hotel solve last month is a typical example - the LED sign at their front desk and the USB port are actually designed in the groove at the top of the screen, blocking it with a magnetic cover. Do you think this design is like hide and seek?

4. Three taboos for interface use

There is a point here! ​ ​The equipment may be burned if the wrong insertion is inserted​ ​, remember:

• Don't just use the charging cable for your phone, the voltage does not match
• After opening the cover of the outdoor screen, the waterproof glue ring must be re-locked
• The U disk is removed in time after the content is transmitted, and it will affect the heat dissipation after being inserted for a long time.

The most outrageous case I have ever seen is that a customer plugged in the USB port as a power port, and the motherboard directly smoked. The maintenance fee is enough to buy a new equipment, so I feel sorry for paying the tuition fee!

5. Personal experience discussion

After working for so many years of technical support, I found a rule:​ ​The more hidden the interface design, the more reliable the screen is.​ ​. Just like the transparent screen we customize for high-end customers, the USB port is hidden in the power supply module and can only be turned on with special tools. Although this design is a bit troublesome, it is not a mistake to touch or damage.

After all, you can’t just look at the surface parameters when choosing a device. When purchasing next time, remember to ask the manufacturer to mark the interface position on the plan diagram, and focus on testing the convenience of plugging and unplugging during on-site acceptance. After all, no matter how good the display is, it will be useless if it is not easy to use, right?
