Hello everyone, I am the TV guy Messi. Many people say Messi. You have tested so many TVs, mid- and low-end LCDs, high-end quantum dots, why don’t there be OLED? OLED is a bit expensive. Is it worth buying ? Messi has a friend who bought a new OLED TV. I am also very curious and just give you a detailed evaluation (a lot of effort, please give me a reward).
Baidu Encyclopedia: OLED
OLED display technology has the advantages of self-luminescence, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high reaction speed. However, as a high-end display, it will also be more expensive than an LCD TV in terms of price.
Why buy OLED TV? What are the advantages and disadvantages of OLED?
OLED TV Advantages: thin, fast response speed, low latency, ultra-high contrast, no light leakage, OLED is born without blue light
OLED TV Disadvantages: has lower brightness and LCD ratio, is expensive, and has a slightly lower lifespan than LCD.
is extracted: it is positioned at high end, focusing on ultra-thin, pure black positions, ultra-low latency, suitable for high-end audio and video pursuits, heavy enthusiasts watching football and gaming.
Speaking of OLED, many people will think of Sony , Samsung, and LG, international brands such as these brands. The 55-inch OLEDs do not seem to be less than 10,000 yuan. Domestic OLEDs (imported panels are also imported). For example, Skyworth and Changhong are roughly around 9,000 yuan, and the cheapest is 7,000+. Compared with the mainstream 55-inch LCD in the range of 3,500-5,000, OLED is indeed much more expensive. In the end, whether high-end OLEDs are reliable, let’s find out this time.
Messi asked: Brother, why do you want to buy this Skyworth 55R8U OLED?
Friends answered: I heard that OLED watches Blu-ray dramas and plays games. The panel is also imported LGD like other OLED TVs. Skyworth OLED seems to have been doing for many years, and it is not bad to read e-commerce reviews, and there are many after-sales outlets, so the price is acceptable (rich).
Highlights: LGD original OLED screen, ultra-thin body, color gamut NTSC92%, response time 0.001ms, refresh rate 120Hz, support MEMC, support Dolby Vision, of course we are a mule or a horse to take a walk.

1. Appearance assembly
Seeing this big TV, Messi was still very excited. He had never tested OLED and was a little nervous.
searched online. This Skyworth 55R8U (4K) is an upgraded version of 55R8 (1080P), using LGD (LG Display, LG Display Company) screen.
OLED TV is really thin and I feel like I can carry it upstairs by myself. I am worried about resisting the pressure, but when I take it apart, I see that there are protections on the upper, lower, left and right, and there is no overturn.
Accessories: Bluetooth voice remote control + multimedia conversion cable + card protection instructions, there is nothing to say.
Base installation: 4 screws, one minute to complete, just like other TVs, installation is not difficult.
Skyworth 55R8U bracket is made of metal, uses electroplating technology (Xiliang), and there is also an anti-slip pad at the bottom. As a support size of 55 inches, the overall size is still relatively stable, without the feeling of shaking and swaying.
remote control comparison: remote control is made of black skin-like material, which feels good and is dirt-resistant. As an OLED smart TV, Skyworth 55R8U is a must-have for Bluetooth + voice function, the actual experience is good, and the control sensitivity is much better than infrared. (PS: This is why Messi has always recommended Bluetooth remote control.)
appearance mainly features narrow borders. Well, how narrow is it? Let's take a look.
5mm PK 15mm (the lower left corner is a regular old TV).
Change the angle, what is the thickness level?
Thanks to the special structure of OLED, the TV screen can be made into ultra-narrow bezels, and even rolled up. At present, some PCs and iPhones have confirmed to use OLED as displays. Messi believes that lightness and ductility are a trend in the future.
The screen is bright, many people want to say that Messi's black edge is so big (actually not wide), and the ID has no border? In fact, TVs and mobile phones have different screen viewing distances. It is not realistic to truly realize a narrow-looking full-screen like a mobile phone, and it is not necessary (unharmed to transportation).
Back: The upper part of the metal is brushed, the lower part of the plastic is integrated, the protruding handle position can be removed as a wall hanging hole, and the wire drawing is very beautiful.
In order to pursue back integration, Skyworth 55R8U body interface has hidden, USB3.0*1, USB2.0*1, HDMI2.0*3, network cable, etc. How to say, all of them should be available, and 3 HDMIs are praised, which basically meet the expansion requirements. It would be better if there are more USB3.0.
2. Image quality measurement:
In fact, the OLED modules that can be purchased on the market are basically from LG Display (LGD, LG Display Company). The same specifications are not much different in color gamut, contrast, screen response time, etc., but there are still differences in color tuning, brightness control, etc. The same sentence is the most important thing, the picture quality is the most important thing, and the actual test starts.
General operation:
resolution is no problem, the font is clear.
Contrast: Except for 1 and 2, can distinguish the other, and the contrast and brightness are good.
Transition: The small triangle below is mostly clear in distinction, and there is a slight stickiness in green, so there is no big problem.
①, Light leakage: OLED show-light leakage, non-existent
Haha, it is not a boast. Since each pixel of OLED can self-luminously emit light and does not emit light when displaying black, LCD TVs require backlight no matter what color they display, so there will be different degrees of light leakage when displaying black (such as the one below).
②, Brightness: Real HDR?
Many people are asking again, Messi, isn’t OLED TVs worse than LCDs? I think how do you play?
OK, let's review the previous Messi HDR certification
single-view brightness: LCD peak ≥800 nits , OLED peak ≥540 nits, it can be said that 100% of the market price below 5,000 cannot reach this one.
value friend asked: What is the difference between watching TV with low brightness?
Messi Answer: The upper limit of the picture details you see is determined by the highest brightness (the actual test below tells you the gap).
Messi test: (Meat pain screen brightness meter)
automatically recognizes HDR videos (HDR10). Messi manually tests the maximum brightness of 529 nits. No official data was found, but it is very close to the 540 nits HDR certification brightness passing line.
Same conditions: This LCD TV (currently delisted, Cool Kai 50A2) has a brightness of 68 nits, which is not wrong for you.
value friends wake up: Wow, isn't it said that LCD brightness is much better than OLED? Isn't this scientific?
Messi answer: Theoretically, the brightness of LCDs will be higher than that of OLEDs due to backlights. For example, the peak brightness of Sony flagship LCD with a peak of 2,000 nits (of course Messi is only heard of), but the brightness of most low-end 4K LCD TVs that do not have regional light control technology is extremely limited. OLED is indeed the main focus of black spots, with no light leakage, extremely high contrast, and pure black pictures, but brightness is definitely a big factor affecting the picture quality.
③, Color: color gamut + color accuracy.
Messi is a cliché. The color gamut is the most direct and the most easily perceived by consumers. There is no need to use special instruments. The higher the color gamut, the richer the color.
Skyworth 55R8U wide color gamut (NTSC above 92%) VS Cool Cache 50A2 (NTSC below 72% ordinary TV)
wide color gamut and ordinary color gamut TV are clear at a glance (of course, transparency and brightness are also related).
④, Anti-shake delay: OLED low latency + MEMC= claims to watch the game, playing the game artifact
before the importance of MEMC function, Messi has been compared many times in actual measurements. MEMC can greatly reduce the shadow drag (the human eye can detect it), there is no doubt about this.
Whether there is any sports compensation:
Higher-end sports compensation VS Differences in ordinary sports compensation
OLED itself has a very low latency, and with a 120Hz screen refresh rate, it can achieve smaller shadows, which is obviously very important for game and game users (Skywit chip model is unknown, only A72+3G+32G).
⑤, original picture PK screen camera
From a comparison, the color restoration is still good, there is no serious color shift in the low color gamut, and the red performance is particularly eye-catching. (Due to camera exposure, the actual performance is slightly better than screen shooting)
Other samples:
millimeter display: put a CAD picture to see its display fineness.
This picture is taken in the picture above, and you can see that the fineness is really good. The font can be distinguished, but it is not impossible to recognize due to light leakage. Messi is curious whether the doctor's monitors are all OLED.
Image quality summary: looks at the color gamut, light leakage, black position, brightness, and motion pictures (delay) from the actual performance. It has to be admitted that this OLED is indeed better than ordinary LCDs, and it does meet the higher-end positioning, which is more suitable for audio and video or game enthusiasts.
3. System UI voice:
As one of the earliest domestic smart TVs, Skyworth basically has nothing to be lacking in system localization applications. Of course, there is not much to say about the current smart TV systems, which mainly depends on the compatibility between members and third-party APPs.
Forgot to say that there are advertisements for booting.
machine test recognition and playback of local content, no problem, A72 chip + 3G memory + HDMI2.0, multiple 4K high-code rate movies can be played, and HDR10 movies can also be automatically recognized.
Voice control:
is very sensitive in actual measurement, and can be used for voice search, fast forward, volume adjustment, etc., but due to resources, most of them need VIP to avoid advertising.
Sound quality:
Since this machine is a 4K OLED entry-level machine, it does not focus on sound quality, and this machine does not have JBL or Harman Katon audio (equipped with the flagship S9A), Messi does not expect it, but the result is better than expected. In terms of actual listening experience, you can hear clearly with a few grids and small volumes. Although it cannot achieve the shock of the Harman subwoofer, the actual listening experience should be better than most 4K TVs I have tested (I wonder if it is a sound quality system bonus?), and it will be a bit metaphysical to go further.
Summary: In terms of system and voice control, Skyworth 55R8U TV performs well, Bluetooth remote control is still easy to use, HDMI 2.0 expansion port is sufficient, voice has certain uses (some scenarios). It must be said that the disadvantage is that there are advertisements on the computer, and it is not like Cool Care to give you 3 years of membership.

OK, the above is the full content of Messi experience Skyworth 55R8U, many friends may say that 8999 buy 55-inch domestic TVs without any cost-effectiveness , it’s better to buy a 65-inch or even 70-inch TV. Is this the truth? Read it down.
At the end of the article,
OLED target population:
OLED's black bit, the response speed is incomparable to LCD, and it is relatively more eye-protective. If this OLED TV can meet the HDR certification standards, it is suitable for users who are extremely pursuing audio and video or games (for them, OLED may be the minimum requirement).
Can you buy domestic OLEDs:
. Domestic OLED prices do have advantages
Messi I want to say that since OLED screens are not as popular as LCDs, the price of OLED TVs is indeed relatively high due to panel costs, etc., but as mentioned at the beginning, only domestic OLEDs have achieved less than 10,000 yuan. In terms of cost-effectiveness, domestic brands must have price advantages. Of course, it is not as simple as the price. It still depends on whether they have real skills.
, OLED, it depends on the real skills
price is cheap enough, so whether domestic OLED TVs are reliable, Messi thinks everyone doesn’t have to make such a decision. At least this Skyworth 55R8U has a peak brightness of 530 nits (close to the HDR certification standard), NTSC's 92% color gamut, and 120Hz refresh rate really bring me excellent black positions, good colors and smooth sports images. If a domestic OLED has excellent picture quality and a certain price advantage, then you can actually consider
