Hey, bosses, do you often encounter this kind of embarrassment? The newly installed electronic screen at the entrance of the store reflects light like a mirror during the day, and is so bright that it can be used as a street lamp at night. When shooting a short video, the screen is full of ripples. Why is it so difficult for novices to quickly gain fans through electronic screens? Today we will explain this matter in detail.

1. Find out the ropes before choosing a site

I went to the building materials market with my friends last week and was stuffed with 17 leaflets in three hours. In fact, looking for an electronic screen is like looking for a partner. You must pay attention to three hard indicators:

• ​​Look at the venue properties​ ​: Seaside shops must choose IP65 protection level (IP54 is enough for ordinary streets)
• ​​Calculate viewing distance​ ​: Choose P4-P6 spacing within 10 meters (pixels below this are obviously grainy)
• ​​Measure installation dimensions​ ​: The screen + bracket weighs 90 kilograms per square meter (old houses must reinforce load-bearing walls)

Last year, a B&B in Pingtan installed a screen on its terrace. It was cheap and chose an ordinary model. As a result, when the sea breeze blew, color patches appeared in half a year. The repair fee was enough to buy half a new screen.

2. Parameter Selection Guide to Preventing Pitfalls

When visiting the market, it is common to see hyped sales. Remember these core parameters:

1. ​​Refresh rate ≥1920Hz​ ​(Below this, there will be ripples when shooting video)
2. ​​Smart brightness adjustment​ ​: The indoor 800-1200cd/m² range is sufficient (the electricity bill increases by 50 yuan per month for every 100cd higher)
3. ​​Contrast ratio from 5000:1​ ​(The higher the number, the more transparent the picture will be)

A smart dimming screen installed in the atrium of a shopping mall in Xiamen automatically adjusts the brightness through photosensitive elements. The electricity bill saved in half a year is enough to buy an air conditioner.

3. Practical skills on installation location

Frequently Asked Questions: Only to find out that the viewing angle is restricted after installing it? Remember these three golden points:

1. ​​Street shop​ ​: 2.5-3 meters above the ground, tilted 15 degrees (visual range expanded by 60% compared to vertical installation)
2. ​​Shopping mall escalator entrance​ ​: The bottom of the screen is flush with the escalator steps (naturally guiding the line of sight)
3. ​​Restaurant booth area​ ​: Install interactive screens at a distance of 6-8 meters (it is easy to accidentally touch them beyond this distance)

An Internet celebrity hotpot restaurant in Quanzhou installed an ordering screen on the wall of the waiting area, and combined with the coupon pop-up window, the waiting time was reduced from 40 minutes to 25 minutes, and the number of Douyin check-ins soared by 300%.

4. Cool knowledge about repair and maintenance

1. ​​coastal areas​ ​: Use neutral detergent to scrub every month (alkaline solution corrodes lamp beads)
2. ​​rainy season​ ​: Check the sealing strip in advance (moisture repair fee is up to 8,000 yuan/time)
3. ​​control card​ ​: Prepare two sets of systems for rotation (life extension 2-3 years)

Editor’s point of view: In fact, choosing an electronic screen is like adding salt to cooking——​ ​I’d rather start conservatively and slowly add features later.​ ​. Industry data shows that screens with intelligent control systems can save 42% in three-year operation and maintenance costs. Especially for models that support remote updates, there is no need to go to the site to change promotional copy in the middle of the night. Remember to ask for a copy of the "Installation Environment Test Form" next time you make a purchase. This is the master's screen selection secret at the bottom of the box!
