Hey, don’t tell me, I really encountered something strange last month. An international shopping mall has installed a five-story transparent screen, which looks like a floor-to-ceiling window from a distance. When you get closer, you realize that an autumn fashion show is being broadcast. What's even more amazing is that standing three meters behind the screen, you can actually see the model's eyelashes clearly - where can I buy this black technology that is both light-transmitting and image-producing?

When visiting the factory, look at these three things first

Let me tell you the truth first. Nowadays, even in electronic cities, they say they can make transparent screens. But something happened at a music festival last year - the screen looked quite transparent during the day, but at night the lights turned into frosted glass. Later it was discovered that the manufacturer had cut corners and added less optical film. A serious manufacturer must prepare these three things:

1. ​​There is a vacuum laminating machine in the dust-free workshop​ ​(There must be bubbles in the hand-applied film)
2. ​​The laboratory has a spectrum analyzer​ ​(Measuring light transmittance cannot rely on visual inspection)
3. ​​Can produce 2000 hours of aging test video​ ​(Three months of accelerated aging is worth five years)

Here’s a little trivia: A screen with 86% transparency is twice as expensive as one with 75%, but the natural lighting it brings can save 40% on electricity bills. According to actual measurements in a shopping mall, the air-conditioning load was reduced by 15% after installing high-transparency screens. This account must be clearly calculated.

The twists and turns in the parameters

Don’t be fooled by sales and just look at the size. It is also a 100㎡ transparent screen.​ ​1920Hz refresh rate​ ​It is 80,000 yuan more expensive than ordinary screens, but the promotional videos produced do not flash streaks. Keep a few key parameters in mind:

• ​​The transmittance must be measured​ ​(Use a laser pointer to illuminate from the back, and the spot diameter is ≤5cm, which is considered qualified)
• ​​Brightness needs to be adjusted in time​ ​(≥5000nit during the day, automatically reduced to 800nit at night)
• ​​Grayscale≥16bit​ ​(The sunset can distinguish 112 kinds of red gradients)

Last year, the curved transparent screen installed in a car showroom suffered a loss. The customer insisted on using a low-grayscale screen to save budget, but as a result, the dark car paint showed up as black spots. Later, a high-grayscale screen was installed, and even the brushed texture on the wheel hub could be seen clearly. Passenger traffic increased by 27% that month.

Hidden secrets in installation and maintenance

You may not know that the most expensive thing about installing a transparent screen is not the screen itself. The steel structure of a suspended screen in a certain science and technology museum cost 60% of the cost. Several key points to avoid pitfalls:

1. Ask if it contains​ ​Shockproof bracket​ ​(It’s useless to save this money and cry when the earthquake comes)
2. confirm​ ​Pre-maintenance design​ ​(Otherwise, you will have to dismantle the entire wall to replace the lamp beads)
3. Must bring​ ​Intelligent temperature control​ ​(Automatic alarm when temperature difference exceeds 10℃)

What's even more amazing is that high-end screens now use "invisibility". The reception screen we made for a hotel is just ordinary glass when it is turned off, and the image is displayed only when it is powered on. This kind of screen is useful​ ​Nanoscale conductive film​ ​, the cost per square meter is 300 yuan higher than that of an ordinary screen, but the maintenance cost saved in five years is enough to buy half a screen again.

Invisible costs are even scarier

Let’s talk about something that subverts the perception – the most expensive thing about a transparent screen is not the hardware but the software. A certain scenic spot installed four-sided interactive screens. It worked fine for the first two years, but in the third year the system upgrade required a new authorization code. Now all reliable solutions are available:

• ​​Open source control system​ ​(You will find someone to maintain it yourself later)
• ​​Modular power supply​ ​(You can replace the broken one without returning the whole machine to the factory)
• ​​Five-year warranty includes system upgrades​ ​(It must be stated in black and white in the contract)

For example, the window screen of a certain brand’s flagship store can change its content according to the weather. Sunscreen ads are broadcast on sunny days, and moisture-proof shoes are automatically cut on rainy and snowy days. What’s behind this​ ​Environmental sensing system​ ​In support. Although the whole set costs RMB 150,000, quarterly sales increased by RMB 2.1 million.

The editor finally tells the truth: Don’t rush to place an order when buying a transparent screen. Go to the manufacturer’s workshop first. Check to see if there is a vacuum defoaming machine on the assembly line, and feel whether the seams of the display screen are flat or not. A truly good screen is like a crystal when it is turned off, but can tell stories when it is powered on. The next time you see a translucent and gorgeous display screen in a shopping mall, you will know how much hard work is hidden behind it.
