Alas, have you ever encountered such embarrassment when you use LED screens? I just installed the screen and was eager to turn on the computer to display it, but I held up the remote control and looked for buttons all over the screen - this thing has no physical switch at all! Two days ago, I met a customer who touched the frame of the transparent screen for ten minutes, and finally found that the switch was actually in the groove of the bracket. Today, let’s talk about this seemingly simple but driving novices to crazy: Where exactly are the switches of the small LED screen hidden?
1. Don't rush to find buttons to understand the three types first
The most common mistake that friends who are new to LED screens is to use all screens as TVs to find switches. In fact, the smart screens are very expensive to play now, and the switch types can be divided into three categories:
-
Invisible Touch Pillars
High-end products like our transparent video walls have evolved into Capacitor sensing areaNow. Just draw a circle in the lower right corner of your finger and turn on the phone. This is the same as the fingerprint under the screen of your phone. A customer thought the screen was broken when he used it for the first time, but in fact he didn't find the activation area [^Company Information].
-
Modular design
Rental screens and floor tiles screens require quick disassembly and assembly, and the switches are directly integrated into Box clampinside. Last time I installed a dance floor screen in a nightclub, DJ stepped on the seventh floor tiles and suddenly turned on the lights in the audience - it was a foot-sensing trigger switch!
-
Remote control
Big outdoor screens and fence screens are all popular now Contactless startup. The mobile app will light up at a glance, and you don’t need to climb the ladder to press the physical key at all. The project we do at the Tokyo Stadium, the administrator can control 16 screens in the audience [^Company Information].
2. Guide to the six major hiding places
Last month, I helped more than 20 novice customers find switches and summarized these high-frequency hiding points. Get the notes:
✅ Side invisibility
75% of the wall-mounted screens will hide the switch on the right frame, so be careful to find grooves with dust cover. There is a trick: use a flashlight to shine it obliquely, and you will see the reflective silicone plug.
✅ Back mechanism
The plastic piece with arrows on the upper left corner of the back of the box should not be considered decoration! Push down half a centimeter and the physical switch pops up. Our rental screen is specially made into a push-pull style, and can be operated with gloves [^Company Information].
✅ Power cord trick
Some simple models directly use the switch to the power plug, and automatically turn on the power three times. This design is quite controversial, but it does save Singapore customers 20% of the installation time.
✅ Remote control blind fuck
Press and hold "Menu + Volume-" for five seconds to force the power on. This trick is suitable for emergency situations where physical switches cannot be found. However, it should be noted that the key combinations of remote controls may be different in different batches.
✅ Intelligent sensing area
The high-end model is like a dance floor tiled screen, which can be awakened by stomping twice. Tested data: The wake-up success rate in an 80 decibel environment is as high as 97% [^Company Information].
✅ Software control terminal
The screen connected through the HDMI cable can be turned on by installing a control software on the computer. A customer didn't realize until three months later that his screen did not use physical switches!
3. Can't find the switch? Eighty-most are these five pitfalls
Last week, I encountered a case that was particularly typical: the customer bought an outdoor screening and unable to turn on the machine, and finally found that the switch position was blocked into the wall during installation. The minefields that novices often step on are highlighted for everyone:
⚠️ The protective design is too good
The IP65 waterproof wraps the switch tightly and you have to use your fingernails to open the sealing ring. It is recommended that the outdoor screen be selected with remote control starting model to avoid climbing high and prying rubber strips.
⚠️ The instruction manual did not explain clearly
Some models need to be plugged in and wait three minutes before activation is activated. Customers think it is a bad machine and directly return the product. In fact, this is the circuit protection mechanism, and it will light up when the capacitor is fully charged.
⚠️ Accessories in reverse direction
The box is upside down and causes the switch to face inward, which is most common at rental sites. Our quick disassembly boxing specially designed to prevent stupidity, and the snap-in is not suitable for the [^Company Information].
⚠️ Standby status misunderstanding
The screen is completely black in low power mode, but the power indicator will blink breathing. Some customers mistakenly thought that the power was not turned off, so they pulled out the power supply and burned the control card.
⚠️ Smart mode conflict
The light sensor misjudged the ambient brightness and automatically shut down during broad daylight. At this time, you have to turn off the light sensing function in the settings, or cover the sensor with your hands for five seconds to reset.
4. If the switch is not used properly, the lifespan is half less
Finding the switch is only the first step, and using the right method is the real ability. Let me tell you a few maintenance tips that only people in the industry know:
🔧 High frequency usage scenarios
For example, if the shopping mall advertising screen is switched more than 20 times a day, it is recommended to turn on it. Soft Start Mode. Tested data: The progressive power-on can extend the life of the power module by 30% than direct power-on [^Company Information].
🔧 Extreme weather operation
-Preheat first in 25℃ environment: Use a heater to blow the interface area for three minutes before turning on to prevent the condensate from short-circuiting. This operation manual won't be written!
🔧 Multi-screen linkage skills
When controlling screens above ten, do not turn on and off one by one. The master sends a start command with a time difference of 0.5 seconds to the slave, which can avoid voltage surges.
🔧 Alternative solutions must be made
We all have three sets of startup methods for the emergency command screens we provide for the government: physical switch + mobile APP + voice-controlled wake-up. Last month, the power was cut off due to heavy rains, and the customer clapped his hands to activate the screen alarm function.
Editor's opinion:
After using LED screens for eight years, the biggest feeling is that the switch design reflects the manufacturer's attentiveness. A good product should allow users to find the switch in three seconds, do not stutter in five operations, and do not worry about using it for ten years. Next time, if you can't turn on the phone, don't rush to smash the screen. Let's first see if any thoughtful design is used as a decorative piece. After all, in this era of pursuing minimalism, the best interaction may be the "invisible sense of existence".
