Vol 2 Chapter 415: Screen determines picture quality

Wu Hao looked at everyone and shook his head: "Yes, since then, we have begun research and development of this product.
So why do we spend so much effort to specifically buy such a dying TFT-LCD panel production plant that is on the verge of closure?
Why not directly seek cooperation with other display panel companies, or directly purchase or build a widely recognized OLED display panel production plant. "
After asking a few questions, he glanced at everyone, and then slowly answered: "In short, these display products on the market did not meet our requirements, so we chose to spend huge sums of money to acquire such a display. Panel production plant.
As for why to choose a TFT-LCD panel, this has our own considerations. "
"With regard to the strength of the two display technologies, LCD and LED, this is actually not only in the industry, but also on the Internet.
The two have advantages and disadvantages, but in the current recognition, OLED technology is much more advanced than LCD technology.
But it also has its own defects, such as burn-in, because OLED screens are organic materials, so it will age faster than LCD screens using inorganic materials. And because the display of the OLED screen is composed of small pixels, each pixel is like a self-emitting LED lamp.
The change in the light and dark colors of these pixels directly determines the change of the display content. It is precisely because of this uneven change, the aging speed of each pixel will be different, and the screen burn-in phenomenon will occur.
In addition, OLED has a major drawback, which is the direct reason why we did not use this display screen. That is, it has a serious strobe problem, and this strobe has a greater harm to our eyes. Although the strobe cannot be seen directly by the naked eye, it can stimulate nerves, cause visual fatigue, and even cause tears and headaches.
Everyone knows that in all VR glasses, the screen is inevitably close to the eyes, which can be said to be in front of the eyes. This way of directly facing the screen, long-term wearing will cause damage to our eyes.
So we must choose a screen that is relatively less irritating and harmful to our eyes, and LCD screens are clearly more dominant in this regard.
Then there is the consideration of screen clarity. We know that pixels make up our screen. Therefore, the more pixels there are at the same screen area, the clearer the screen becomes.
However, the OLED screen pixel arrangement will cause the two screens to have the same resolution, but the screen clarity will be worse by 1/3. So with the same resolution, the OLED screen is not as clear as LCD.
Because our eyes are too close to the screen, we must require this screen to have a high resolution, so that the picture we see will be more clear. Otherwise, the picture you see will be very blurry, and even all fruits or mosaics.
Having said that, I have to admire the previous users of VR glasses with mobile phones. How did you endure such poor picture quality? "
Hehehehe ... Everyone laughed, there was indeed a flood of VR glasses, so many companies took the opportunity to launch their own VR glasses. Said to be VR glasses, is actually a VR box for mobile phones, consisting of only a few simple lenses. The mechanism is simple and irritating, and the picture quality is naturally not to be said.
But that's it, there are still many people who are keen to buy fooled. It is precisely because of the unscrupulous marketing of these companies that VR technology has rapidly cooled down, and even once dropped to freezing point. It has only slowly returned to the public after the technological development in recent years.
Taking a sigh of relief, Wu Ha swallowed his throat and moistened his throat, then went on to say, "So for all these reasons, we have chosen the TFT-LCD display panel technology which is more advantageous in this respect.
Of course, this does not mean that LCD display panels have no disadvantages. It has a lot of disadvantages, such as the colors are not bright enough, the power consumption is relatively large, the screen display response time is relatively slow, thicker than the OLED screen, can't it be bent and folded like the OLED screen and so on.
Therefore, after acquiring this TFT-LCD panel production factory, we did not rush into production, but began a long process of production process transformation and technology research and development upgrade. Those who follow us know that in the past few years we have applied for a series of patents on display panels and display technologies, so that many people think we are going to enter the mobile phone and laptop TV industry. "
"No, we have been building a high-quality screen for this VR eye from beginning to end. Fortunately, the hard work has not been wasted. We did it. We successfully developed a new generation of LCD based on the original TFT-LCD reality panel technology. Display panel technology.
I won't say more about the specific data, I will only mention a few keywords here. 8K, 240HZ, wide color gamut, low frequency flash, all of which we have on this screen. "
"What is 8K, it is four times the resolution of 4K, which means it is clearer and more delicate than the 4K screen we see. That is to say, even if you look at this screen up close, you will still It is very clear. And this will bring us users a more realistic experience, and make our users feel as if they are in the real scene.
What you see is almost identical to what you see in the real world outside. Of course, in order to achieve this effect, you must also have such a high-definition image. This aspect belongs to the content category, so I won't talk about it. "
"The 240HZ high refresh rate guarantees the continuous smoothness of our display. That is to say, on our screen, you can fully experience the 120-frame ultra-high definition that can only be experienced in high-definition digital cinema. Movies allow you to see subtle changes that are hard to see on ordinary screens, and feel the shocking feeling that this high-definition picture quality brings to us.
Next is the wide color gamut ~ EbookFREE.me ~ low frequency flash, I will not introduce more of these two. Our new generation of LCD display screens has undergone a series of improvements and optimizations in real-world technology, enabling it to achieve more beautiful colors than those OLED screens on the market today.
Here are two comparison charts. You can take a look. This LCD screen using our new technology is fuller and more colorful than the screen using OLED technology. You can test and compare this, we are very confident about it.
As for low-frequency flicker, this is the advantage of LCD screens. It is just that we have optimized and improved on this basis, so that the index and frequency of its strobe have been lowered. This can further protect our eyes and minimize the series of discomforts that occur when users wear VR glasses for a long time. "
Having said so many professional data at once, Wu Hao's brain was hypoxic. Fortunately, I have remembered these before, so I can still carry them.
After taking a sigh of relief, he smiled again: "How about, this screen is great. In the future, we will also actively cooperate with some mobile phone, notebook and TV manufacturers to promote this screen and use it. Among the various display products that benefit the majority of consumers, they bring shocking visual effects that have never been seen before. "
