Hi~welcome to shenzhen xinmu display technology co., ltd.!
Alas, have you ever thought about why the surveillance screens with red light in chemical plants will not explode in high temperature and high pressure environments? Last year, a friend who was in the mining industry suffered a great loss. He bought an ordinary LED screen to install it in a mine with a cheap price. As a result, the equipment was short-circuited and sparked, which almost caused an accident... Today we will talk about this explosion-proof surveillance...
Alas, have you always heard people say that the louver LED screen is light and wind resistant recently? But when I wanted to install this kind of screen, did I suddenly realize that who should I find this thing? Don’t worry, let’s take you to find out the tricks here today! 1.

Alas, have you ever wondered why the large screen on the concert stage can instantly change the scene? How to make the huge advertisements in the shopping mall atrium so that the picture is sturdy? This matter has to start with the eighteen martial arts of LED splicing screens. As a display engineer who has been in the industry for ten years, today I will take you to open up the industry's tricks and ensure that you can compare to the sales design after reading...
Have you ever seen a large LED screen with black screen in a shopping mall? Eighty times the heat dissipation is not done and the chips are burned! Today, let’s talk about this problem that is easily overlooked but fatal - where should LED screens dissipate heat? ▍Where does the heat come out? If you take apart the screen, you will understand: the temperature of the driver chip can reach 85℃ when it is working...
How to layout the heat dissipation structure? The three-level heat dissipation system forms a closed loop of thermal management: Module-level heat dissipation: The thermal conductivity of aluminum-magnesium-zinc alloy box reaches 205W/m·K, 3 times faster than traditional materials System-level flow diversion: The honeycomb air duct design increases the air flow rate by 120%, and the actual cooling of the tropical areas is measured...
Ouch hey! Have you ever encountered such crazy moments? The LED screen I just bought suddenly faded, and the repairman asked: "What version of this screen is yours? "The question was confused on the spot! Today we will look at this problem that makes Xiaobai’s headache - where is the LED screen version hidden? (Down the sound) Stealing...
Alas, when I was watching short videos recently, I always saw moving product advertisements floating in the shopping mall windows, and the subway station channel suddenly turned into an underwater world - are you also curious about where this black technology is done? The novice Xiaobai wanted to get a transparent LED screen to install a store, but when he searched the Internet, he was full of professional terms, which made people's brain hurt. Don't...
"Are you also wondering where the LED screens that turn around in the mall are installed? "Last week, I helped my friend find an advertising space, and I wandered around the commercial street for three times but couldn't find the control room. This is really not an isolated case - last year's industry report showed that 43% of merchants would take 25 days to confirm the location for the first time to install a special-shaped screen. Today we will...
Why do scrolling subtitles always get out of control at critical moments? Many users find that when the LED screen needs to display fixed information, scrolling subtitles are as difficult to stop as if they are magically cast. This situation often stems from the cognitive fault between system settings and hardware operations—82% of equipment failures stem from improper operation. 1. Soft...
1. Core parameter decoding: Understand the technical language behind the model Pixel spacing (P value) is the core indicator of model naming, for example, P2.5 means the spacing between lamp beads is 2.5mm. This parameter directly affects the display accuracy and viewing distance, and needs to be combined with the spatial depth of the installation environment and the mobile line...
Technical threshold behind customization requirements Recently I encountered a funny and hilarious case: a shopping mall insisted on customizing wavy LED curtain walls, but it took three suppliers in three months to complete the process. This reminds me that customization of special shapes is far from being as simple as changing the shell. A truly professional service provider must have three major abilities:...
1. Comparison of differences in core luminescence principles Question: What is the essential difference between LED and LCD screens in basic working principles? answer: LED displays adopt self-light diode arrays, each pixel is directly illuminated by a red, green and blue three-color LED chip. LCD displays rely on backlight...
