▲ Organic light-emitting diode screen display principle
The following are the advantages and disadvantages of OLED screens.
Organic light emitting display
Organic light emitting diodes are also called the third generation display technology. Organic light-emitting diodes are thinner and lighter, with low energy consumption, high brightness and good luminous efficiency. It can also display black and can be bent. For example, the current curved screen batteries and folding mobile phones all use organic light-emitting diode screens. These advantages enable international manufacturers to strengthen their investment in the research and development of organic light-emitting diode screens, and make organic light-emitting diode screens widely used in TV, computer monitors, mobile phones and other fields.
▲ Organic light-emitting diode flexible screen display
Advantages of the OLED screen: Compared with the traditional LCD screen, the thickness of the LCD screen is about 3mm, and the thickness of the OLED screen can be controlled within1mm. The OLED screen has anti-aging function and a wide viewing angle, which is not available in the LCD screen. The organic light-emitting diode screen is also resistant to low temperature, which can display the content normally at minus 40 degrees, which is environmentally friendly and can also be made into a curved screen, giving us a better visual experience. The color of OLED screen is brighter than that of LCD screen. Offscreen fingerprint unlocking and off-screen photographing can be realized through OLWD screen, but the LCD screen cannot realize off-screen fingerprint unlocking and off-screen photographing technology due to its complex internal structure.
▲ The OLED screen shows DC dimming.
Disadvantages: OLED screens are made of organic materials, which are easy to age and lead to short life, commonly known as screen burning. Moreover, the light emitted by the OLED screen is very dazzling, and the eyes will be uncomfortable after watching it for a long time. Because the light emitted by the screen is dazzling, there are technologies to adjust the principle of screen lighting. There are two dimming technologies, DC dimming and PWM dimming. Among the two dimming methods, DC dimming is better than PWM dimming, because the OLED screen is not dazzling and looks more comfortable after DC dimming.
Although Huawei's Nova7 mobile phone uses an organic light-emitting diode screen, the organic light-emitting diode screen is dimmed by DC, so you don't have to worry about the glare of the organic light-emitting diode screen when using Huawei noba7. Eye protection has also passed the German new TUV global eye protection certification, which is more comfortable and eye protection.
abstract
Organic light emitting diode (OLED) is the only soft screen display technology with large size, high brightness, high resolution and high refresh rate among all display technologies. It will be widely used in 3G communication terminals, wall-mounted TVs, desktops and laptops. , but also can be applied to the military, the application is extremely extensive.
Hello, I'm glad to answer this question for you. Let's take a look at the detailed configuration of this phone first.
1. Basic configuration of mobile phone: Kirin 9855g SOC160.64× 74.33× 7.96 mm weight 180g6.53-inch organic light-emitting diode single hole straight screen aperture 3.9mm screen accounts for 20: 9, and the resolution is 2400× 1080.
2. The screen of Huawei Nova7 adopts a 6.53-inch oled screen with a resolution of 2400 x 1080, arranged in a diamond shape. The screen ratio is 20:9. Support p3 wide color gamut, and also have the eye protection certification of Rheinland, Germany. This screen is not top-notch, but it is quite satisfactory.
3. Shopping suggestion: Huawei's Nova series aims at taking light and thin photos, targeting slightly poor women. If you want better performance, you can choose Glory 30 Series.
4. The above are my answers and suggestions, which I hope will help you.
What about the screen of Huawei Nova7? First of all, Huawei Glory's mobile phone screen basically adopts the screens made by JD.COM and Tianma. Compared with the Samsung super AMOLED screen used by other mobile phone manufacturers, there is still a certain gap.
Why is Huawei HONOR's screen made in China? As we all know, at present, Huawei pursues profit maximization, reduces product costs as much as possible on the basis of ensuring the general user experience of products, and at the same time raises product prices through brand influence to obtain maximum benefits.
In order to pursue greater profits and not be blocked by the upstream supply chain, Huawei began to make a large number of domestic products in recent years, which means that many spare parts of Huawei products currently bought are domestic materials. For consumer electronic products such as mobile phones, it basically belongs to secondary development and component integration, especially relying on supply chain. For example, screens, camera modules (excluding sensors, mainly from Sony and Samsung), batteries, mobile phone structural molds, etc. It has been basically localized on mobile phones.
Everyone should know that there is still a gap between domestic mobile phone spare parts and international manufacturers. Of course, not only mobile phone parts, but also key parts of other industries such as automobiles and aviation need to be supplied by overseas companies. It is precisely because there is a big gap between the design and production technology of domestic related parts and components and international manufacturers that the prices are not the same. Take the mobile phone screen as an example, the domestic screen is probably within 800 yuan, while the screens of international manufacturers such as Samsung basically start at 1 1,000 yuan, and the top screen of Samsung is more than 1 1,500+,so the price gap is still obvious.
At present, Huawei's largest screen supplier is domestic BOE, followed by Tianma, Sony and South Korea's LG. However, these screen manufacturers are far behind the screen giant Samsung in terms of technical strength, patent number and market share. It can be said that Samsung has monopolized more than 80% of the global market share of OLED screens, and its strength is very strong.
Let's go back to the question itself, that is, what about the screen of Huawei Nova7? Just yesterday, Huawei released Nova7 series mobile phones, including Nova7SE with LCD screen, Nova7 with OLED screen and Nova7 Pro with straight screen, while Nova7 Pro with curved screen. The specific screen parameters are as follows:
Huawei nova 7se: 6.5-inch LCD screen with resolution of 2400* 1080, single hole in the upper left corner and physical fingerprint on the side.
Huawei Nova 7:6.53 inch 2400* 1080 resolution single hole straight screen.
Huawei Nova 7 Pro:6.57-inch 2340* 1080 resolution dual-hole screen 70 curved screen
The screens of these three mobile phones are BOE and Tianma, and the screen display effect is doomed to be inferior to other flagship mobile phones with Samsung screens. At present, the organic light-emitting diodes are divided into Samsung's "diamond arrangement" and BOE's "Zhou Dongyu arrangement", and the display effect is quite different. For example, domestic screens are not as good as Samsung screens in terms of color gamut, brightness, uniformity and wide viewing angle.
Of course, it's not that domestic BOE can't make high-quality organic light-emitting diode screens, but in order to maximize profits, Huawei often doesn't use domestic screens. For Huawei's Nova series, it is even more impossible to use a better domestic screen by imitating the "high price and low allocation" style of OPPO and VIVO mobile phones. Compared with the Nova series, it focuses on young fashion and photo experience, and the screen display effect is average. At present, even the flagship model of Huawei P40 series, Huawei's BOE screen is not top-notch. Compared with Black Shark's mobile phone, it also uses domestic BOE screen, but Black Shark 3 series uses BOE top diamond arrangement, while Huawei P40 uses Zhou Dongyu arrangement:
For Huawei Nova7 mobile phone, we can see that the screen resolution of this organic light-emitting diode is 1080p, and the screen refresh rate is 60HZ, only 16700000. Compared with other mobile phones' screen refresh rates of 90HZ and 120HZ, and supporting hundreds of millions of pigment display and HDR 10+ high dynamic images, the screen display and operation experience are completely different!
To sum up, if you want to pursue the screen display effect and smooth experience, you basically don't need to consider Huawei's honor. The screen of Nova7 mobile phone belongs to a very common domestic organic light-emitting diode screen, which is not the same as the Samsung super AMOLED screen used in other domestic mobile phones.
What material is the screen of Huawei Nova7? How is the display effect?
First of all, the screen on Nova7 is an organic light-emitting diode screen arranged in Samsung masonry, and the screen quality is very good. For Huawei and glory's mobile phones, the screen may be the most concerned issue. For example, people often ask whether the screen is an organic light-emitting diode or an LED, and whether the Zhou Dongyu arrangement is a masonry arrangement. You may also often hear people say that LCD garbage, Zhou Dongyu garbage! Are they really rubbish? Will these factors really seriously affect the display effect of a screen? Let's analyze it for everyone, and you can also learn it!
What's the difference between LED and organic light emitting diode? Which is better or worse? LCD and OLED are mainly made of different materials. Generally speaking, the screen of organic light-emitting diodes will be more beautiful, with higher contrast and more pleasing to the eye. Therefore, in order to cater to consumers, most mobile phones now adopt organic light-emitting diode screens. Even the glory family, which has always adhered to LCD, has switched to organic light-emitting diode screens in the glory 30 series this year. The LED screen is mild and doesn't look so gorgeous, but the LCD screen has one advantage, that is, it doesn't hurt the eyes so much. Although organic light-emitting diodes look gorgeous, they will make eyes tired after watching them for a long time, so there are still many people who like LCD screens! So this can only depend on what the personal focus is, there is no difference between the two!
What's the difference between masonry arrangement and Zhou Dongyu arrangement? First of all, these two arrangements are aimed at OLED screens, mainly because the arrangement of screen pixels is different, so why are they called masonry arrangement and Zhou Dongyu arrangement? It's actually quite simple. It is named after the shape of their pixel arrangement. As the name implies, masonry arrangement is the arrangement of pixels on the screen, which is very similar to masonry and is the arrangement of Samsung screens. Zhou Dongyu arranged BOE's screen, while Zhou Dongyu was the star. Why is the screen arrangement called Zhou Dongyu arrangement? In fact, because the expression pack of a little yellow duck in Zhou Dongyu is very popular, and the pixel arrangement of Zhou Dongyu's arrangement is very similar to that expression pack, so everyone likes to call it Zhou Dongyu's arrangement!
Which is better, masonry or Zhou Dongyu? Under the same conditions, the display effect of masonry arrangement will be better than that of Zhou Dongyu. There is nothing to say about this. What about under the same conditions? That is, the color difference of the screen is the same as the color scale, the resolution is the same, and the brightness difference between the highest brightness and the lowest brightness is the same, because the display effect of the screen depends not only on the arrangement of pixels on the screen, but also on other factors.
Then why is the arrangement of masonry better than that of Zhou Dongyu under the same conditions? In fact, the main reason is that the pixel loss rate of Zhou Dongyu's arrangement is relatively large. For example, the screen with 1080P at the same time and the screen with Zhou Dongyu arrangement have an actual resolution of only 720P, which is almost what this means. Of course, the loss is not that big. Here is just an analogy for everyone to understand! In that case, the display effect will definitely be less delicate.
Summary: Anyway, what is the screen display effect of Nova7? First of all, the digital V@ Xiaobai evaluation has been tested. Nova7 uses Samsung's masonry arrangement, and there is no problem. Then it also supports the wide color gamut of DCI-P3 and has passed the latest German Rheinland eye protection certification. So friends who like Nova7 don't have to worry about the quality of this screen!
Hello, let me talk about my opinion.
In terms of screen information parameters and screen size, Huawei nova7 adopts a 6.53-inch full screen, and the punching area is reduced by 23%. In terms of screen material, Huawei nova7 chose organic light-emitting diodes. On the screen pigment, Huawei nova7 supports 6.5438+0.67 million colors. On the screen resolution, Huawei nova7 supports 2400* 1080 pixels. On a pixel per inch, Huawei's nova7 is 403PPI. In touch mode, Huawei nova7 is a multi-touch capacitive screen. In terms of touch characteristics, it is a conventional gesture operation. In terms of screen characteristics, Huawei nova7 supports DCI-P3 wide color gamut. In terms of screen HD, Huawei nova7 supports 20:9 FHD.
At the same time, Huawei nova7 supports fingerprint unlocking in the screen, which is a bit "Sao operation". In addition, Huawei's nova7 screen has also passed the German Rheinland New T? V global eye protection certification increases the consistency of screen color difference and brightness level fluency in different environments, which is more comfortable and has better eye protection visual effect.
In short, in my opinion, the screen is still relatively conventional, in the current mobile phone market. Watching the press conference yesterday and shooting at the same time was a highlight. I hope I can help you!
Hello, questioner! First of all, thank you very much for answering this question here. I'll take you into this question and have a good discussion.
The hyperboloid design on the front and back of Huawei nova7 brings a slimmer feel. Based on Huawei's industry-leading 5G technology and flagship process chip, the bottom thickness of the fuselage of Huawei nova7 is about 7mm, the top thickness is about 8mm, and the weight is controlled at around 168g, which is rare in the industry.
As the flagship of 5G selfie video, Huawei's nova7 front camera is quite luxurious, with 32 million focus-chasing dual cameras, the industry-leading flagship ISP image processor, and the autofocus lens with super AI engine, which brings accurate eye focus and realizes selfie or selfie video. The distance is clear.
Huawei nova7 rear 64 million main camera lens adopts11.7 inch super-large photosensitive element and f 1.8 aperture. The actual shooting effect is as follows, which truly restores the colors of the sky and trees, and also restores the layering of clouds. In addition, nova7 series also supports "AI beauty shooting", but it is difficult to distinguish when shooting distant objects.
Huawei nova7 is equipped with SLR BM3D image denoising technology after turning on the super night scene mode. From the imaging point of view, the lighting part of the photo is not overexposed, the color of the sky is relatively pure, the overall photo has almost no noise, and the picture looks very pure.

Hello, I'm Qin Bo, the creator of the digital field. Thank you for reading.
How about Huawei nova7 screen?
Huawei nova7 uses an organic light-emitting diode screen. So what are the advantages of organic light-emitting diode screens?
First, the OLED screen is very thin, but the thinness does not affect the display quality.
Second, organic light-emitting diodes can be folded at will like origami, which gives mobile phones more modeling possibilities.
Thirdly, the organic light-emitting diode display screen has a high contrast, especially when it displays black. Because of its self-luminous principle, organic light-emitting diodes can bring true black color as long as the luminous mechanism is turned off. This is also the principle that organic light emitting diodes can realize off-screen display.
So overall, the mobile phone experience of Huawei nova7 is very good.
The appearance is fashionable, light and thin, and the feel is particularly good. The number in brackets can get the number 7 color, which is particularly beautiful, just like a mirror, showing different colors under the sunlight. Fingerprint and facial recognition are very sensitive to unlock, even if the hand print is shallow, it can be unlocked quickly. The sound effect is good and the sound is crisp. Took a few photos, very clear, almost no difference from the original. It runs fast. Long standby time, no need to charge for one day. The charging speed is fast, and it feels good to be satisfied with shopping after a few days. I bought two Huawei mobile phones for this 6 18 event, and I feel very good. The screen of this Huawei Novo7 5G mobile phone is 6.53, and the size is just right. You won't feel overwhelmed if you hold it in your hand. The photo effect of the mobile phone is also very good, and the picture is beautiful. The photos taken are very artistic. The speed of turning around is also very fast, and headphones, chargers and transparent mobile phone cases are also given away. I bought it in JD.COM, and the products from JD.COM can be delivered the next day. JD.COM is great. Fingerprints and facial recognition are very sensitive to unlocking, and I like them very much. My fingerprints are so shallow that I can't brush them off on my old mobile phone. I'm very upset. I don't have this trouble now. I opened it as soon as I received the goods. The appearance is amazing and beautiful, and the fingerprint is unlocked quickly. The previous mobile phone may have been used for a long time, the operation and memory are absolutely enough, and the response speed is very smooth. It's the first time to use a 5g mobile phone. Jingdong logistics has always been like this.

The screen size is just right for girls, and there is no pressure to hold it in one hand. Photographing effect: the rear camera has four shots and 64 million main cameras, and the photographing effect is uneven, while the front camera runs at almost one speed: the mobile phone is equipped with Kirin 985, 8G running memory and 256G storage space. Mobile phones operate smoothly and quickly, and girls use fewer games. I believe that if you want to play, a big game like the glory of the king also has a stress-free standby time: under the condition of 4,000 mAh battery, it is no problem to use it normally all day, and the mobile phone is turned on a lot.

Running speed: very fast, 8g storage is very good. Standby time: useless. Let's talk about other functions after use: a very satisfactory shopping.
Fingerprints and facial recognition are very sensitive to unlocking, and I like them very much. My fingerprints are so shallow that I can't brush them off on my old mobile phone. I'm very upset. I don't have this trouble now ~ I'm used to using it silently, so it doesn't matter how the sound effect is. The photo effect is great! Anyway, it must be better than the old mobile phone. Running speed? Of course, it's a new mobile phone. Swish, come on! I don't know the standby time yet, after all, I will comment as soon as I get it. Well, I'm still trying. The first time I used Huawei, everything felt very fresh.
Appearance: exquisite and beautiful screen sound effect: excellent photo effect: clear and beautiful, strong running speed: smooth and not stuck, standby time: extra long, other features: it's the second time to use Huawei mobile phone, the first time was 6 years ago, and this time it's really amazing, beyond my expectation!

But it's easy to leave fingerprints on the back cover, so it's much better to use the phone case! Screen sound effect: the screen color is exquisite, and the sound effect is good after listening to a few songs. Photo effect: I tried to take a few photos, which were very clear and had a good beauty effect, but I felt that the color was not as real as that taken by Apple, but other functions were better than that of Apple. Running speed: new machine, running speed is very fast, try it later. Standby time: I used it all morning after receiving it, and there is still a lot of power. I feel that it should be longer than Apple's standby time. Apple mobile phone must bring charging treasure when going out. Other features: I placed an order yesterday and received it today. JD.COM is trustworthy! It's the first time to use Huawei's mobile phone. The system needs to adapt and take some time to review!
Birthday present, little surprise! Empty bird blue is pure and beautiful, and girls can operate it with one hand. The whole machine uses the cloning function, and all the old mobile phone information is imported, which is very convenient. 8+256 top matching, the running speed is also quite powerful. Taking pictures has its own beauty function. Charging is very fast. No shortcomings have been found so far. Perfect!
