Alas, Xiao Wang, who runs a milk tea shop recently, asked me: "I want to build a transparent LED screen in Changshun as a window. Where should I do this thing? "This made me scratch my head - now there are display screens all over the streets, but the reliable transparent screen suppliers are like pearls in milk tea. There are actually few companies with real materials. Let’s talk about this today, so you can feel clear after reading it.

First understand what kind of transparent screen you want

Transparent LED is not an ordinary display, this thing is​​High enough light transmittance does not affect the product​​. There are three levels on the market:

• ​​Basic model​​: The light transmittance is about 60%, it looks like it is covered with yarn during the day, suitable for warehouse signs
• ​​Advanced​​: The light transmission is about 80%, and it is suitable for our milk tea shop windows to use this
• ​​Top style​​: Translucent translucent exceeds 90%, dedicated to bank gold shops, you can buy a small car for the price

The key point is here! ​ ​A very professional transparent screen with smart dimming​​The brightness under the sun can soar to 7500cd/m², and will automatically drop to 800cd/m² at night without any dazzling sight. The window screen of the milk tea shop that I installed for the customer last time was tested for IP65 protection in heavy rains. The rainwater flowed down the screen, and the milk cover tea displayed inside could be seen clearly.

Three ways to find suppliers

1. ​​The most reliable way to inspect the factory​​
   There is a display industrial park around Changshun. Just go to the workshop to see three points:

   • ​​Laboratory equipment​​: The factory without a spectrum analyzer is withdrawn as soon as possible, and the color accuracy cannot be guaranteed at all.
   • ​​Aging test bench​​: All serious screens need to be continuously roasted for 72 hours, and the temperature reaches 50℃ and does not cover the screen to be considered qualified
   • ​​Installation case library​​: You need to see the actual installation video of the same type of store. The installation requirements of milk tea shops and clothing shops are completely different

2. ​​Compare the parameters and compare prices​​
   The transparent screen is too deep, and the same size quotation can range from 8,000 to 30,000:

   • ​​Lamp bead brand​​: Imported lamp beads have a lifespan of 50,000 hours, two years more than domestic ones
   • ​​Power supply solution​​: A total of 30% electricity savings for the total driver, three-year electricity bill savings and double-door refrigerator
   • ​​Control system​​: 15% more expensive with content management system, but can remotely exchange advertisements on your mobile phone

3. ​​After-sales team must be professional​​
   There was a tragic case last week: the customer asked the guerrillas to install it cheaply, but the screen leaked and the circuit board burned. ​ ​All serious manufacturers are equipped with a 24-hour response team​​, with thermal imager to inspect and repair, 90% of the faults can be solved within 2 hours.

Pit avoidance guide (blood and tears experience)

Recent acceptance discoveries​​Three Dark Thunders​​：

1. ​​Transparent virtual mark​​: The promised 80% light transmission, the actual measurement is only 65%, which is like a matte film attached
2. ​​Splicing light leak​​: Bank cards can be inserted into the joints of the module, and this screen must be short-circuited during rainy season
3. ​​Power supply stolen work​​: Install the outdoor screen power supply indoors and be scrapped in three months

I'll teach you some testing methods:​​Turn on the flashlight to shine on the back of the screen​​, a good product is evenly transmitted and without dark spots. Last year, the 86% light transmittance screen was installed for a chain milk tea shop. It was as clear to see the products from outside the store on sunny days as if they were not installed.

How to control the implementation cost

The transparent screen is not done just by installing it.​​Three years of comprehensive cost must be calculated clearly​​：

• ​​Electricity bill​​: Use a 10㎡ screen with a total negative solution, and save electricity per year to make 2,000 cups of milk tea
• ​​Maintenance fee​​: The screen failure rate of regular manufacturers is less than 3% in five years, and the annual maintenance fee for miscellaneous screens is enough to buy new screens.
• ​​Content update​​: The system with cloud platform can save on advertising company design fees, and you can change pictures on your own mobile phone

To give a real case: After a certain milk tea brand changed its transparent screens in 20 branches in Changshun, its customer flow increased by 40%, and the customer stay time increased from 7 seconds to 23 seconds. The key is that it saved 1,200 yuan per month of electricity bill.

Personal advice

Finding a transparent screen supplier is like picking the raw materials for milk tea - don't just look at the price list, you have to test the samples to see the effectiveness. Three must-have tests:

1. ​​See the brightness under the sun​​: Stand 5 meters in front of the screen at 12 noon, the picture is clear and not reflected
2. ​​Water splashing test waterproofness​​: Use a mineral water bottle to simulate rain, and the water flow cannot penetrate into the joints
3. ​​Watch soft light at night mode​​: The light after automatically dimming at night should be soft and not like a searchlight

Finally, remind novices: be sure to write down the contract​​Color gamut coverage ≥110%NTSC​​, this parameter determines whether the color of the milk tea is displayed is correct. When accepting, a red apple is placed on the screen. The difference between the red and the actual color displayed on the screen cannot be seen with the naked eye.
