Is it worth buying if there are small black dots on the inner screen of the Apple 13 mobile phone?

A mobile phone with a small black dot has an impact on the visual effect, which will make you feel unaccustomed to looking at the phone, if you can afford it, you choose an Apple mobile phone, it is recommended to change to an Apple 14

It's also good.

If it's second-hand, and** it's very cheap, you can start, if it's new, I don't recommend starting, there are small black dots indicating that there is a problem with the screen, it is not recommended to start.

Apple inner screen has minor flaws can be purchased, provided that our mobile phone is already a second-hand Apple mobile phone, if there is no overhaul value, you can buy some cheap small defects of the inner screen to use, but we need to consult the merchant in detail before buying the screen to avoid being deceived.

There are dark spots on the screen, which are generally caused by leakage from the LCD screen.

Most of the liquid crystal screen leakage is damaged by external force, that is, under pressure. It's basically man-made damage.

If there is a test screen on the Internet**, you only need two full black and white sheets. In the case of a black screen, if there are no bright spots, and there are black spots on the white screen, it is almost certain that it is dust and not a bad pixel. To make further determination, you can observe it from several more directions from the side of the screen, and if there are certain angles where the black dots are not visible, or if a keen friend can see or feel the black dots on the screen, then it is certain that it is dust.

In addition, if you can see bright spots under a black screen, it must be a dead pixel.

This is the bad pixel of the screen, and you can go to the after-sales service for free to replace the screen.

The dead pixel of the LCD screen, also known as point absence, refers to the sub-pixel points displayed under the black and white color of the LCD screen and the three primary colors of red, yellow and blue, and each point refers to a sub-pixel. The most feared thing about the LCD screen is the bad pixels. When a dead pixel occurs, a point on the display will always show the same color, regardless of the image displayed on the display.

This "dead pixel" is unrepairable and can only be solved by replacing the entire display.

ProblemAccording to the default standard in the industry, "dead pixels" are a "normal" phenomenon, but they cannot affect normal reading. A certain number of bright spots or dark spots and dead pixels in notebooks and mobile phones are a characteristic of LCD display technology, and such a phenomenon is inevitable for any manufacturer.

Nowadays, devices such as iPhones are assembled with higher and higher precision, and some internal parts are mostly disposable. The after-sales maintenance environment and assembly accuracy are definitely not as good as the "foundry", if the dead pixels of the screen do not affect the normal use, it is recommended not to easily go to the after-sales service to replace the screen.

Summary. It's okay, use it first, if the black area is large, it won't work.

Dear, hello, you switch between different software** to see if the black block is still there. If the display content is different and the black dots are in the same place, it may be that the screen is abnormally pressed and the pixel is broken. Generally, it does not spread well.

Hardware issues. The maintenance needs to replace the entire display component,** If it is not too low, it will be judged to be lead, and then it will be upgraded to the level of envy after a while.

Let me see. Isn't it a fall.

It's like a leak. Didn't fall.

Dear, I look like I'm leaking.

inside the inner screen.

So what to do about it.

It's okay, use it first, if the black area is large, it won't work.

Missing a night requires a screen change.

Is there no way to fix it.

It's not easy to repair. It does not affect the use of the first repair.

Good. Uh-huh.

Answer: Hello, dear, the black spot on the screen of the Apple mobile phone is because: it is very likely that the screen is leaking. First of all, press the part of the black spot with your hand to see if there is liquid crystal flowing, if there is, the screen is damaged; This situation is generally caused by the screen being squeezed, resulting in damage to the light-emitting diode (triode) tube circuit inside the screen and failure to work normally; It is recommended to go to the after-sales service for inspection and maintenance.

Ask what causes it.

If the screen of the iPhone is squeezed, there will be problems with the screen parts inside, or the liquid inside the phone will squeeze and leak.

If you encounter a screen leakage situation, the Apple mobile phone is still within the warranty period, it is recommended to go to the after-sales inspection and maintenance, if it is not within the warranty period, go to the repair shop to replace a screen, or you can prepare tools to replace the screen.

Finally, put the disassembled mobile phone in a dry and noisy place, preferably for about two days, and then install it.

After the return period, the after-sales service will definitely not agree to return the product, if the after-sales agreement to change the screen is also possible, but it must be repaired at the designated point of the brand, otherwise it may be replaced with an ordinary screen with poor quality on the market, but the problem of bad pixels of the LED screen is not big, it does not affect the use, and it will not be expanded, just a visual effect, more of a psychological effect, in fact, many LCD screens we commonly use will have bad pixels, but no one will often pay attention to them, most of them are just a little flaw in the screen manufacturing process.

If you look for customer service for Air China, you must return it.
