Nowadays, copycat is more and more powerful. Not only do mobile phones have various copycats, but also some accessories, such as iPad screens, can be classified as original and copycat. How can we distinguish something that is difficult to identify in appearance, such as a screen? Many readers may have heard of the method of using water drops to verify the original iPad screen, as follows The verification process is presented to the majority of computer users:

Test object display:

Original iPad screen (the same as the toothpaste test last time)

The iPad is a fake screen (it is a real iPad, but the screen is fake, and the original screen is the one above)

Drops of water:

Original iPad screen

Counterfeit iPad screen

You can see that the water drops on the original screen are very round and full, a bit close to the water drops on the lotus leaf, and they will keep a good shape when the screen is tilted; The fake screen is soft and collapsed, and there is a feeling of "stab" around it, so it is lifeless. Then Xiaobian uses a pen to remove the water droplets:

Counterfeit iPad screen

You can see that the water drops on the original screen have been pushed away to form two small water drops, while the water drops on the fake screen are a bit messy, which seems a bit "muddied".

Why is that? After searching for information, Xiao Bian learned that there is a special coating on the original iPad screen, that is, a super hydrophobic surface is made of hydrophobic micro particles or nano particles on the screen, which increases the tension on the screen surface, making it difficult for oil stains to attach, and water droplets will form like lotus leaves due to the effect of surface tension. Due to the cost and process, the fake iPad screen has not added this layer of antifouling film, so it can not form full drops like the original iPad screen.

So, can this method be used to identify counterfeit mobile phones? Love to play computer games I just bought two shanzhai some time ago Millet 2 , I can just take it for a try.

The effect of side shot is more obvious

What about other brands of mobile phones? The other two domestic mobile phones Meizu MX2 and Oppo Ulike 2 that Xiaobian is good at have tried, and the results are as follows ：

More and more people use smart phones, and many bad businesses use fake screens instead of original screens to make huge profits. However, mobile phone screens can't tell the difference between fake and original screens when viewed with the naked eye (unless it is clear that it is a fake product). In fact, the method tested by Xiao Bian today is not very advanced technology, but the copycat can only choose a cheap scheme due to the cost. Of course, there are many ways to identify fake mobile phones. This method is just an interesting one for entertainment.
