This problem is not solved, OLED screens still have a "minefield"!

OLED, Organic Light Emitting Display, Chinese called organic luminous display technology, was once known as "dream display technology", and now it has been "rotten street" in the mobile phone market. Of course, "Bad Street" is not to demean OLED, but to illustrate the commonness of OLED in the mobile phone market, but rather to say that in addition to watching for a long time after all, "tired eyes", OLED is far better than the traditional LCD screen in terms of brightness and color.

As OLED screens become mainstream in the mobile phone market, after the production capacity of OLED panels continues to increase, display panel manufacturers are also looking for new sales markets. The TV market bears the brunt of it, and OLED TVs, which were originally priced at more than 10,000 yuan, can now be moved home with only a few thousand pieces.

After the TV market, the notebook computer market has become the next target to be targeted, starting from 2021, laptops using OLED screens have begun to appear frequently, and the price has dropped significantly compared with similar products in previous years.

This problem is not solved, OLED screens still have a "minefield"!

With the tide of OLED screen popularization coming to the second year, last year it was ten minutes of love with OLED, and ASUS, which launched OLED laptops in multiple product lines, once again brought us a new product - asus peerless series. After the launch of ASUS Peerless, many small partners are in the background to ask whether Xiaolei this computer is worth buying, OLED screen is good to use, etc., since everyone is curious, then Xiaolei will talk to you about the advantages and disadvantages of OLED screens.

Is OLED screen easy to use?

What are the advantages of OLED screens? This question is actually very easy to answer, higher brightness, more pure color, higher contrast, etc., OLED compared to the traditional IPS in a number of parameters have a significant improvement, for the user perception gap is also very obvious. There is no need to even put the two computers together for comparison, as long as it is a user who uses the IPS screen for a long time, he can feel the difference between it and the IPS at the first time he sees the OLED.

Compared with the traditional IPS screen, OLED screen has many advantages, for friends who like to use laptops to chase dramas, watch movies, and play games, the improvement brought by OLED screens is very obvious. Because OLED screens generally support Windows' native HDR mode, after turning on HDR mode, players can open the HDR option in the game and enjoy the real next-generation screen.

This problem is not solved, OLED screens still have a "minefield"!

Why do traditional IPS screens not support HDR mode? There are two main reasons: one is that the contrast is not enough, can not meet the standards required to open the HDR mode, the contrast is not enough to force the HDR will only lead to the picture overexposure, or even less than the conventional mode; the second is that the brightness is not enough, the traditional laptop IPS screen brightness is often limited to 300 nits -350 nits, a few will reach 450 nits or 500 nits (MacBook), the screen under this brightness can only meet the most basic HDR standards, If you force it on, it will not work well either.

To put it simply, the traditional IPS screen is basically incompatible with the HDR mode on the laptop because of the inherent deficiency (mainly heat and cost problems), resulting in the HDR mode of the Windows system being reduced to a decoration on the laptop most of the time.

For the IPS screen is difficult to solve the contrast and brightness problems, in the face of the OLED screen is not even a problem, OLED screen can accurately control the switch of each pixel, by completely closing the specified pixel points to achieve extremely high contrast (in theory, the contrast of OLED is infinite, depending on the upper limit of brightness), and the brightness of the OLED screen can easily reach more than 800 nits (taking the iPhone as an example, the peak brightness is as high as 1200 nits, The local brightness of some domestic mobile phones is even as high as 1500 nits).

This problem is not solved, OLED screens still have a "minefield"!

It can be said that if you want to popularize HDR on laptops, there are only two options of OLED or mini-LED, and in the short term, only OLED can be popularized, mini-LED is a better choice, but it still faces a variety of problems such as capacity, cost, yield rate, etc., and is only used in small batches for some high-end displays and tablets (iPad Pro).

What are the advantages of OLED screens other than supporting HDR mode, allowing laptops to enjoy Dolby Vision movies online? As a screen panel that people have high hopes for, OLED's advantages naturally go beyond color, brightness and contrast (although these are already the three most important parameters of a screen), OLED because of the different IPS way of illumination, so its response time is much lower than that of traditional IPS.

For gamers, response time has always been a major pain point for game laptops, and it has only improved in the past two years after fast liquid crystals have become mainstream. Before the rapid liquid crystal popularization, most gamers on laptops had to endure a response time of more than 6ms, and excessively high response time for FPS players can directly affect the game experience and player play.

If you are a player who owns both a gamebook and an esports monitor, as long as you have tried to play the same FPS battle game on the gamebook's own screen and esports monitor, it is easy to find the experience gap between the two. The game's general response time of 3ms or even higher makes the afterimage on the screen longer, and the high frame rate makes the situation even more serious.

This problem is not solved, OLED screens still have a "minefield"!

At present, there are very few products in the game book that can achieve a response time of 1ms, and many of them are "processed" from 3ms to 1ms through technical means. Although it is enough for most players, it is obviously unacceptable for the "hardcore players" who can blame the win or loss on going out one step further today, resulting in excessive physical exertion and insufficient strength to pull the gun and lose the game.

The OLED screen can meet the requirements of these players, taking the OLED display launched by Asus as an example, the response time is only 0.1ms, even lower than the upper limit of the human eye's perception time for picture changes. In simple terms, no matter how fast your screen spins under the OLED screen, there will be almost no smear problems (unless the brightness is too low or the number of frames is too low), which is the perfect solution to the needs of "hardcore players".

OlED screens have inherent advantages in entertainment, and as long as the cost is reduced to the level of IPS, it will have a crushing advantage. Since OLED screens have so many advantages, are there no disadvantages in addition to high costs? Of course not, OLED has many disadvantages, and they are quite "fatal".

The "fatal" drawback of OLED

OLED does have many advantages, but some of its disadvantages are also what we must face. As I said earlier, OLED is controlled by controlling the display of a single pixel, and olED pixels have an upper limit on life, when the life is exhausted or stays in a brightness for a long time, there is a chance of failure, such as can not be extinguished, can not be lit, etc., this is the most fatal problem of OLED - burn screen.

In the early days of OLED's entry into the mobile phone market, many head manufacturers' mobile phones are facing the problem of burning screen, so that OLED screens once became a selling point that mobile phone users avoided, until later through the two-way improvement of technology and system, the problem of burning screens was gradually solved, and users accepted OLED screens.

Although the OLED screen used on laptops is already a new generation of materials after technological upgrades, the problem of burning screens still exists, and it is more likely than mobile phones to burn screens. Because the continuous screen light time of the computer is often in hours, sometimes even the screen is turned off once in the morning until the night is turned off.

In the process of brightening the screen, more than 70% of the pixels of the bottom taskbar of Windows are in a static state, if there is no targeted optimization, it may only take a month on the OLED screen, you can get a "permanent taskbar", even if you enter the full-screen mode, the bottom taskbar will still stubbornly "stick" to the post.

This problem is not solved, OLED screens still have a "minefield"!

In addition to the problem of burning the screen, the power consumption of the OLED screen is also worth paying attention to, although the overall power consumption ratio of the OLED screen is better than the IPS screen, but because the brightness is much higher than the latter, the actual power consumption is often higher, and the actual battery life of the OLED notebook with the configuration in the relevant test is 20% lower than that of the IPS version.

For notebook manufacturers who have been working hard to improve the battery life of thin and light costs, OLED screens can directly make their battery life optimization efforts "once back to before liberation". In addition to battery life, the PWM dimming of the OLED screen will also increase the burden on the eyes, which is simply that your eyes are more likely to enter a state of fatigue when using the OLED screen.

In addition to the above shortcomings, there are still some system problems to be solved, such as the color management problem of the Windows system, because of the lack of corresponding color management mechanism, resulting in the use of high color gamut OLED screen when Windows will appear color disorder problem.

It can be seen that the shortcomings of OLED screens are not many, and they are quite "fatal", so is olED screens not worth buying? Non-also, Xiao Lei believes that in terms of the current OLED laptop price, it is actually worth starting, because of the shortcomings mentioned above, major laptop manufacturers have already begun to solve.

Taking ASUS as an example, their OLED laptop comes with an OLED management program, which will prevent a certain part of the pixels from being activated for a long time by timing the fine-tuning of the display area, and the built-in color management system will take over the color management of Windows, so that the color advantages of OLED can be released normally. OLED's PWM dimming problem can also be solved by borrowing the analog DC dimming method of the mobile phone, so the only thing that lacks a specific solution may be the power consumption problem.

Therefore, for film and television game lovers OLED screen is completely worth a try, as for the work party, Xiao Lei suggested or choose the traditional IPS screen, and wait for OLED to be more mature before starting. However, Xiao Lei has been able to foresee that in the next time, we should be able to see a large number of OLED laptops on the market, and perhaps there will be surprises or surprises.
