Let me start by asking a heart-wrenching question: How many old LED screens do you have at home? Or are there piles of obsolete displays in company warehouses? Do you feel that these "iron lumps" take up space and cannot be sold at a high price? Don't worry, today we will break down the secrets of this industry and explain them clearly.

(Some newbies may ask after seeing this: Isn’t the LED screen just the big screen used to display advertisements in shopping malls? In fact, it has many more ways to play than you think! From the scrolling subtitles in street barber shops to the giant floor tile screens at concerts, to the service guide signs at bank counters...)

​​Lesson 1: Understand the "ID card" of LED screen"​​
First figure out what kind of product you have - it is a single color and can only display red letters.​ ​Word screen at the door​ ​? Can still play videos​ ​Full color advertising screen​ ​? Or for high-end places​ ​Transparent interactive screen​ ​? The price difference between different types of recycling is more than ten times. For example, the dual-color screen mentioned in page 7 is currently sold for 50-80 yuan per square meter in the second-hand market, while the P2.5 full-color screen with touch function can be sold for 300-500 yuan.

​​Lesson 2: Five major channels for screen closing​​

1. ​​Professional recycling company​ ​: Look for companies with "Electronic Waste Disposal Qualification". This type of company will bring a spectrometer to detect the attenuation of the lamp beads (webpage 6 says "the dead spot rate is less than 0.001%" is a good product)
2. ​​Equipment refurbishment factory​ ​: Specializes in screens that can be salvaged, such as the stage rental screen with a transaction price of 486 yuan/square meter on page 3
3. ​​Cross-border traders​ ​:Notice! What foreign traders like most is the ultra-thin car screen mentioned on page 4. A Shenzhen company’s transaction price of 64.6 yuan/PCS hides huge profits.
4. ​​Electronic component dismantler​ ​: The driver IC, lamp beads and power supply are sold separately, suitable for completely scrapped screens.
5. ​​Special scene recycling​ ​: As mentioned on page 8, special attention should be paid to the handling of lightning protection modules when dismantling outdoor screens. Experienced masters can sell second-hand protective boxes at 30% of the new price.

​​Lesson 3: Don’t step into these pitfalls​​
A fan complained to me: "Last month I sold 20 of my company's conference room screens, but later I found out that the common cathode driver chip used in them was worth 15 yuan each!" "Here are the key points for you:

• Look at the power supply: one with intelligent temperature control (like the liquid cooling system mentioned on page 5) is 3 times more expensive than an ordinary power supply.
• Check the interface: HDMI2.1 interface that supports HDR10+ is now the most popular
• Gray scale measurement: Take a video with a mobile phone. If there is flicker, it must be a low-end scanning mode (the price difference between 1/16 scan and 1/4 scan mentioned in page 7 is 40%)

​​Soul torture session​​
Q: My screen parameters say P5 and 4500cd/㎡. How much is it worth?
A: For example: There is a P8 outdoor screen on web page 2 with a transaction price of 58.9 yuan/square meter, while the P5 screen has a premium of 25% for each level. But pay attention! The higher the brightness, the better. For example, if the screen used in the basement exceeds 4000cd/㎡, it will be discounted.

Q: They say on-site inspection is required. Can online transactions be possible after the epidemic?
A: Really good recyclers require three types of videos:

1. Wipe the module seams with paper towels under a completely white screen (check the aging of the waterproof glue)
2. Play the 256-level grayscale test image (the key to color transition emphasized in Web Page 6)
3. Disassemble the control card and take a picture of the chip model (the SM768G04 chip is 80% more expensive than the conventional one)

​​Technical flow secrets​​
Nowadays, the industry is seriously involved. Only by knowing these things can you sell at a high price:

• The recycling price of screens with "low brightness and high gray" technology (which can maintain color levels even in dark environments) will increase by 15%.
• A unit board that can be used to assemble a curved screen (see if there are pre-installed angle adjustment buckles on the back)
• A power supply that has passed 30,000 hours of aging testing (touch the outer casing to see if it has expanded or deformed)

​​Finally, let’s be honest​​
A restaurant owner came to me two days ago and said that the door screen he bought in 2018 cost 20,000, but now the recycler only gives 800. I asked him to take a look at the parameter list - what a guy! This screen actually uses the naked-eye 3D module mentioned on web page 3, and was eventually sold to a film and television company for a 6-fold increase. So, don’t rush to make a move, first understand the actual value of the assets on hand.
