My friend Lao Zhang, who just opened a store, has been worried recently - the display screen that costs 30,000 yuan, has a serious reflection in broad daylight like a demon mirror. The milk tea shop next door uses a transparent screen to cause constant traffic. Is this money unjust? Today, let’s talk about how to choose these two screens so as not to suffer losses.

​​1. Technical Differences: What is the difference between this enemy?​​
Let me tell you a big truth first: LCD screens are like good students, and LED screens are like sports students. The LCD screen illuminates the LCD molecules against the backlight, suitable for fine display in small spaces ； The LED screen self-luminous body combination plays a big scene.

Last week, I passed by the shopping mall atrium, and the three-story circular screen was a masterpiece of LED. On the other hand, the bank counter is all the LCD screens that show the exchange rate - there is a deep way here!

​​2. Application scenario: choosing the wrong screen type will cost people's lives​​
​​LED screen three main venues​​：

1. ​​Outdoor advertising​ ​: The brightness under the sun reaches 7500cd/m², and IP65 protection can be carried on rainy days
2. ​​Stage performance​ ​: 1920Hz refresh rate has no ripple, and the pores are still visible from 10 meters away
3. ​​Commercial space​ ​: 86% transparent screen, which does not block light and can play interactive

​​LCD screen specialty​​：

• ​​Conference room report​ ​: 4K resolution displays report details
• ​​Retail windows​ ​: The monthly power consumption of 55-inch screen saves 60% compared to LED
• ​​Security monitoring​ ​: 7x24 hours of running without getting hot

The most outrageous case I have ever seen - a gym installed an LCD screen by the swimming pool, and the screen was splashed in three months. This money saves you enough to buy three professional waterproof LED screens!

​​3. Common Misconceptions: I've stepped on these pitfalls for you​​
​​Question 1: Which one to choose for home improvement TV? ​ ​
The living room has good lighting and the basement audio and video room must be selected for LCD. Last year, I helped my relatives install a home theater. Laser LED TVs were 20,000 yuan more expensive than LCDs, but the color reproduction was really a gap that could be seen by the naked eye.

​​Question 2: How to save money on small shops? ​ ​
LCD is used for cashiers, and LED transparent screen is used for window displays. When a certain jewelry store uses mixed and match, the decoration cost has been reduced by 40%, and the passenger flow has tripled.

​​Question 3: Which one is the best maintenance company? ​ ​
The LED modular design is really delicious! I have seen the screen change in the mall with my own eyes, and the master can handle it in 20 minutes like a Lego player. Replace the LCD screen with backlight? The whole machine has to be returned to the factory within two days.

​​4. Purchase Guide: Three Soul Questions​​

1. ​​How bright is the display environment? ​ ​ Select LEDs for direct sunlight, and select LCDs for soft light in indoor
2. ​​How far is the viewing distance? ​ ​ The LCD is delicate within 3 meters, and the LED is domineering within 5 meters
3. ​​Content update frequency? ​ ​ Change materials every day and choose LEDs, and select LCDs on fixed screens

There is a smart way for a restaurant owner to install an LED screen at the door and place a dynamic menu, and use an LCD screen to display the dishes in the dining area in the store. After this combination, the average customer price rose by 15 yuan.

The editor also fell into trouble during the renovation. The picture was cheap and installed an LCD splicing screen in the exhibition hall. As a result, when customers looked at the plan, they always said that the picture was broken. Later, I gritted my teeth and changed the LED, and the number of orders signed in a single month actually doubled. I want to tell you, this thing is like wearing clothes - you have to change your clothes on different occasions, and you have to save this money, but the loss is a real money business!
