Are shopping mall window advertisements always blurred? Maybe the brightness was not selected correctly
Have you encountered this situation? I spent a lot of money to install the advertising screen, but the picture seemed to be covered with dust during the day. Actually, there is a key indicator here that has been ignored—— Brightness dynamic adjustment technology . It is recommended to choose an intelligent dimming model of 800-1200cd/m² for indoor environments. It is installed in semi-outdoor scenes such as glass curtain walls, and it must be able to reach 4000cd/m². There was a restaurant chain owner who bought a fixed brightness screen with a cheap photo, but it was dazzling at night and was forced to shut down the machine for rectification.
► Three principles for procurement lightning protection
Novice gets these three pitfalls most often:
Here is a comparison list:
| Trapped behavior | Correct operation | Cost impact |
|---|---|---|
| Select a fixed brightness screen | Intelligent dimming technology | Save 37% on electricity bill |
| Ignore the heat dissipation design | Select aluminum magnesium zinc alloy box | Lifespan is 2.3 times longer |
| No aging test | 72 hours continuous playback detection | Failure rate drops by 81% |
► The nighttime effect is bad? Low-glass high-gray technology is the key
You may ask: "Why are the screens of other people's advertising screens still clear at night? "The secret is Level 4096 grayscale control . If the brightness of the ordinary screen drops to 20%, it will be blurred into pieces, but this technology can keep the dark details layered. According to actual test data, the image recognition of the display screens using this technology increases by 73% during dusk, which is particularly suitable for window displays after shopping malls are closed.
► Hidden tips for saving money when installing and maintaining
Now the new quick dismantling structure really disrupts the industry:
There is an overseas project case: the 200㎡ arc screen adopts modular installation, with a construction period from 45 days to 22 days, saving 170,000 yuan in labor costs alone.
► Hard indicators for global scenario verification

Editor's opinion
When buying LED advertising screens, don’t just look at the price! Focus on the manufacturer Is the monthly production capacity exceeding 10,000 square meters、Is there any full process record of quality inspection? . I heard that some small workshops do not even perform aging tests, and this kind of screen will definitely cause trouble after half a year. Next time I go to the factory, remember to touch the seams of the box - the workmanship is rough, and the waterproof performance will definitely be reduced!
