Have you ever encountered this situation? The promotional screen at the entrance of the restaurant was not responded for a long time, and the shopping mall guide screen was clicked three times before the page could be redirected. Last week, my friend suffered a big loss when he opened a coffee shop - the touch screen I bought was stuck in PPT when scrolling, and the customer thought the machine was broken and the review was directly negative. Today we will talk about how to choose a display that can touch and move.

1. The three major touch screen crash scenes

1. ​​Milk Tea Shop Tragedy​: A brand used ordinary advertising screen to change touch, but the milk stain penetrated and caused three months of waste.
2. ​​Supermarket shopping guide is embarrassing​: The operation of wearing gloves failed, and the conversion rate plummeted by 55% in winter
3. ​​Showroom Disaster​: The screen tear up during scrolling playback, and the customer mistakenly thought it was a device failure

These cases all point to the same problem—​​Buy the display device as a touch device​​. A truly easy-to-use touch scrolling screen must have three elements at the same time:

• ​0.5mm touch accuracy​ (Can identify rhinestone patches on manicure)
• ​Anti-glare coating​(Visible angle under strong light ≥178°)
• ​​Millions of touch life​(It can be used for five years if you set 3,000 times a day)

2. Word game in parameters

The merchant said that "super sensitive touch" may require hard pressing; the 4K high-definition model may be just clear static images. These parameters need to be focused on:

1. ​1920Hz refresh rate​: The key to scrolling subtitles as smooth as silk
2. ​​＞200,000 rolling life​: According to the calculation of 500 scrolls per day, it can take 400 days
3. ​IP65 protection level​: It is definitely good to deal with milk tea spills and PM2.5

There is a test trick: ask for a demonstration​Quickly slide electronic menu​​, only those who can see clearly the price of each dish are not vaguely considered qualified. The most exaggerated test I have ever seen - touching the screen after sprinkling flour, and can accurately identify finger tracks.

3. Purchase channel pit prevention guide

These common tricks on online platforms:
√ Showcase videos with professional cameras to shoot slowly
√ "Military Quality" is actually second-hand chip assembly
√ The promised installation service will be paid 200 yuan/㎡

It is recommended that suppliers provide:

1. ​72-hour aging test video​(Continuous playback does not get hot)
2. ​Touch track record diagram​(The marking cannot have jagging)
3. ​Three-year failure rate statistics table​(Monthly average failure ≤0.3%)

I have a practical experience of a restaurant owner: let the salesperson play the "Piano Block" game with the touch screen, and only those who can pass the level smoothly will place an order. Although this method is damaged, it can really test the hardware strength.

4. Installation location determines life and death

It turns into scrap iron in minutes when installed in the wrong place:

• ​​Hotpot restaurant open area​: Steam will cause the touch control of ordinary screens to fail
• ​Children's Paradise Entrance​: Naughty kids slap causing sensor damage
• ​​Open-amp Square Edge​: Thurstorm and water accumulation trigger short circuit

The solution is actually very simple:

1. High temperature zone selectionActive cooling type​(15% more expensive than passive cooling)
2. Installation in densely populated areas​Rising glass​(Cost +800 yuan/㎡)
3. Dust-loving environment​Monthly cleaning​​(Save 60% of the repair cost)

There was a shopping mall equipped with interactive screens next to the escalator, but was hit by a suitcase three times a day. Later, it was replaced with a belt​Buffered wall-mounted model​, the maintenance fee was directly reduced by 70%.

5. Price fog cracking technique

The quotation says "8,800 yuan per square meter", don't be tempted. These hidden fees may increase your blood pressure:

• Touch calibration software actually needs to be purchased (9,800 yuan/year)
• The rolling bracket is charged for accessories (380 yuan per piece)
• System upgrade fee per time (2,000 yuan/time)

Teach you a ruthless trick: ask for a contract to be noted​Total five-year holding cost​​, including electricity bills, maintenance, upgrades and other expenses. The overall cost of high-quality equipment is 43% lower than that of bargains, which many novices cannot figure out.

6. Soul questioning: Is the touch screen really necessary?

This question depends on the usage scenario. It is more cost-effective to use traditional posters in convenience stores, but if you are a parent-child restaurant, the interactive screen that can play can increase the average customer price by 28%. There is a very interesting data: the ordering screen with game function can extend the customer's stay time from 3 minutes to 18 minutes.

But don't make this mistake - a bookstore spends a lot of money to install touch screens, but the elderly don't know how to use them, and young people find it troublesome. Later changed to​Solid key + touch dual operation​, the usage rate is only increased.

Editor's opinion: Some merchants now regard "imported chips" as an excuse for premium prices, but in fact, domestic solutions have long broken through the technical bottleneck. Focus onTouch point rateand​Error touch rate​The most realistic suppliers you have ever seen dare to ask customers to test on-site with markers - the real ability is to accurately mark when scrolling.
