What does the so called perfect screen mean for a notebook?

Edgeless screen, the screen ratio is harmonious.

It means that there are no dead pixels and bright spots on the notebook.

After it appears, it is possible to replace the laptop screen, not a notebook.

No bright spots and dark spots, change the screen.

This promise is only: ASUS! Others are unclear, including associations.

The so-called perfect screen is that there is nothing on the screen that can be seen by the naked eye, dark spots, bright spots and dead pixels. If you don't look very closely, you won't look at it, and you need to switch to a solid color screen to distinguish various points, such as pure black test highlights. You don't have to worry too much about the actual purchase, as long as you look carefully and you can't see it, it's no problem.

You don't see it in normal use.

The color is bright and there are no bad spots, and there are almost no flaws.

Due to the physical properties of liquid crystals, dead pixels are as unavoidable as errors in the production process, but the probability is controllable.

No dead pixels, no bright spots, no color spots, no blemishes. It's the perfect screen.

According to the national quality inspection standards, the LCD screen is qualified within three bad pixels, and it can be replaced only if it exceeds three bad pixels and five color points, but for users, one point is intolerable.

In the process of merchant sales,In fact, which batch has more bad pixels,That batch has fewer bad pixels,You have a good idea,You want to buy a perfect screen,You can negotiate with the merchant,Want a perfect screen,Whether you want to pay more,It depends on how you negotiate。

Generally, high-end notebooks have undergone strict quality inspection, and there is very little chance of dead pixels, and there are more low-end notebooks.

That is, there are no blemishes, no bright spots, no bright lines on the screen. You can test it from a special test software on the Internet, that is, force the screen to change various single tones in full screen, and then check it yourself. Generally, if the merchant keeps the perfect screen, he will charge additional money, but it is not excluded as a direct guarantee.

This is a grade statement in the LCD industry, which means: no flaws, no bright spots, no bright lines, and no marks on the LCD screen. The meaning of the LCD screen is of high grade, and it does not involve other parameter issues.

It's gambling. If there are bad spots in disassembling a screen, give the merchant money to open another one (depending on your character), and if there are still bad spots, add money to open it again.

Perfect screen refers to no dead end,When purchasing, use software to test red、Yellow、Blue、Green、White、The color of the black screen is not correct,There are no black dots and black lines,The black screen is not flooded,The viewing angle is large,The brightness will not be too low。

A perfect screen is an LCD (screen) display with no dead pixels (bright spots, dark spots, color dots).

Hello! Perfect Screen:

No bright spots, no dark spots, no bad spots.

Look at the all-white picture - no color cast, all white.

Look at the whole black picture - no light leakage, no white reflection.

1. Concept.

The perfect screen is an LCD (screen) display with no dead pixels (bright spots, dark spots, color dots), no color deviation and bright spots, no light leakage, no scratches on the screen surface, and no signs of damage to the coating film.

2. Detailed. 1、"Perfect Screen:"This kind of statement is also a new term created by the mainland computer market, which we often say"A screen"The same is not a strict original standard. At the beginning, it was created by applying part of the description of the original panel classification"A screen"This seller advertising slogan, later"A screen"The term is used too widely in the market, and the innate end-user (in fact, in good conscience) cannot, and does not need to be strictly demanded"A screen", resulting in a decrease in its gold content. And the sellers have to constantly compete fiercely, in order to show our family"A screen"With their family"A screen"It's not the same, it's not adulterated, it's true, there you have it"Perfect Screen:"Finish.

2. Usually the display manufacturer adopts a warranty policy of 3 points (the total number of bright spots and dark spots on the screen does not exceed 3) for the liquid crystal display sold. Some manufacturers' service is better, and if the factory display has a bright spot, it will be replaced, for example, the U series of dell displays, AOC, and some high-end series of ASUS are all highlight. The definition of perfect screen is that the screen is in good condition, without any bright spots, dark spots, and color spots.

Even without a single light leak. This standard is currently not committed by any manufacturer.

It's very simple, the first step is to set the desktop background color to all black to observe whether there are bright spots, and the second step is to set the desktop background color to all white to observe whether there are dark spots. If there are bright spots, you can find them when you turn them on, and it's easy. I've seen a screen with a dead spot, it's easy to find, don't worry too much, generally don't protect the bad pixel business, the probability of a dead pixel screen is about 10% or less.

This is very difficult to get! It's best to find a computer vendor that can keep the highlights! Look at the screen is to turn on a lot of colors** Cross switching! You can see it!

A+ screen is free of dead pixels, A screen is less than three dead pixels, and the national standard allows less than three dead pixels.

The meaning of LCD perfect screen and A screen is as follows:

1. Perfect screen: Perfect screen is an LCD (screen) display with no dead pixels (bright spots, dark spots, color dots), no color deviation and bright spots, no light leakage, no scratches on the surface of the screen, and no signs of damage to the coating film.

2. A screen: A screen refers to a liquid crystal (screen) display with no spots (within 3 bright spots and dark spots or no more than 5 bright spots and dark spots combined) and stable display without jitter, and meets the above standards under TFT-LCD professional test software.

The relationship between the perfect screen and the A screen is as follows:

1. "Perfect screen" is a new term born on the basis of "A screen".

"Perfect screen" is a new term coined in the computer market in Chinese mainland, and like "A screen", it is not a strict original standard. Because the word "A screen" is used too widely in the market, and the innate end user cannot and does not need to strictly require the so-called "A screen", the saying of "perfect screen" was born among sellers.

2. "Perfect screen" and "A screen" both refer to the screen without spots.

"Perfect screen" and "A screen" are both used to describe the best of the display, the imaging is complete, and there will be no spots, dark spots or bright spots. Both expressions mean the same thing.

A perfect screen is a screen that has no dead pixels and bright spots. A screen is a screen with better quality.

Perfect screen, that is, there are no flaws, normal screen, A screen is the display screen within three checkpoints.

When the products produced by the LCD panel factory leave the factory, they are graded according to the performance indicators of the products, brightness, color gamut, contrast, etc. There are serious blemishes, spots, etc., and cannot be shipped from the factory. This is due to the limited yield of the production process of LCD panels, which cannot reach 100%.

A screen is to point out the better screen in the factory, of course, it may also be a relatively good screen in the hands of the person who sells the display. The ordinary screen is worse in terms of indicators. I think it's mainly the spots and the difference in color. As for perfection, it's top-notch.
