According to historical records, the first time "curved" appeared in the emperor's face in Chinese history.
"Biography of the Ming Dynasty" records that Zhu Yuanzhang "has a strange and weird appearance, indecent appearance". He is known as a shy emperor. In modern language, there is a sheep lying on his face. You should understand it in seconds!
What? Was it popular in the Tang Dynasty? The students who posted the rebuttal described it as not called a curved surface, it was called a "spherical surface"!
Items with concave curves also appear frequently in folk daily life, such as sharpening boys into men, destroying iron pestles into fine needles, and whetstones over the years.
Since there is not enough process to make flat mirrors, ancient wealthy women used polished bronze mirrors to wear makeup. In order to gather their faces in a short distance, the "beauty mirror" also has a concave shape slightly raised on the edges.
Entering modern society, the emergence of "surface" begins to have a sense of technology. In underdeveloped energy areas, "solar stoves" were invented using the principle of concave convergence, and you can burn a pot at any time on sunny days.
The same principle was later widely used in the design of satellite antenna receiver
Entered the communication era. In order to fit the handsome and stupid face, the first generation of mobile phone "big brother" designed it into a concave appearance, which is a reflection of the humanization of technology.
However, this half-moon phone was quickly replaced by smaller flip machines and straight boards. Except for LG's sudden whim that released two generations of Flex curved screen phones in 2015 (and finally ended in vain), there has never been a "concave screen" in the history of the mobile phone.
concave curved screen pattern has since been abandoned by the mobile phone industry!

Episode 0 TVs were the first to use CRT technology. Its silver screen is bulging outwards, and its huge body shape deeply imprints the quantification word "one" of TV in your memory - you are still using it now, aren't you?
Display tube TV's "silver screen" is not deliberately made into a convex surface to meet the reasons only available on ergonomics. In an environment of imperfect technology, the convex surface is naturally formed in the production process because the glass facing the center of the earth is irresistible to resist gravity. Male students should all understand this principle when calming down.
Later, the "right-angle" imaging tube TV appeared on the road of TV development. Although it looked more realistic than the deformed images displayed by the old convex surface, it still failed to produce a larger screen plane under gravitational conditions, and consciously faded out of the market under the strong demand for larger sizes.
Sensually speaking, the later years of CRT technology were bitter tears. Before his death, he had a "enlargement surgery" to please users, and turned into a rear projection TV. However, because the display effect was too poor and the size was too large, it soon disappeared. It was replaced by longer, larger and thinner LCD (liquid crystal) technology TV.
Friends who are good at speaking in English can safely call LCD TV TFT-LCD LED TV.
Maybe you are afraid that users will say the two Chinese words "LCD", so the statement about LCD TV is getting less and less. Brands such as South Korea☆☆☆, Qingdao "Hai Deep Thought" simply deny that their TFT-LCD products are called LCD TVs, but instead change their names and names, and insist on calling them "some LED".
Completely forget your roots
Believe me, they are all the same if they are stripped off
LCD CELL is like a separate small window, which blocks or passes through the light source through the light. I won’t go into details about the specific principles of
because it’s too profound!
It is worth noting that the inner layer of the LCD panel is actually very layered. If the LCD panel wants to be "lit up", it must rely on the backlight source on the last layer of the module to provide light.
Without the "sun", the moon will lose its light
Backlight technology has shown diversified development over time, with the direct-down style of light source "bird's eye view", horizontal style of "right-right" style, partitioned arrangement, LED style of quantum dot materials, etc.
During the growth of LCD, the unique "self-luminous" undercover PDP has been mixed in. It looks the same as LCD but it is self-luminous. However, because Panasonic and other teammates were closely grasping the technology and refused to open it. Although the picture quality was extremely excellent, they could not withstand the torrent of low-cost LCD technology, PDP was removed from the TV team prematurely at the age of less than ten.
No one would have thought that TFT-LCD TV, which had just entered adolescence, suddenly became confused around 2013. LCD technology encountered the ceiling after the 3D concept. Since technologies such as 4K resolution were not yet popularized quickly, TVs were quickly pulled from luxury goods to daily necessities. With the emergence of smartphones, the turn-on rate of TVs also showed a low tide.
In order to solve the problem of losing momentum in the high-end TV market and connecting with the yellow and blue, South Korea's "Xingxingxing" with panel production capacity artificially bending the LCD screen, multiplied the price by 3. In 2014, it officially launched the first LCD concave screen, named " curved TV ". There is a rumor in the public that someone asked privately why the curved screen was built. Xingxing replied: Because only our family can do it!
If the above rumors are true, and if you use classical Chinese to evaluate it, it will be really "Fragrant Grass Sky".
Because another large-screen technology with self-luminous display characteristics is emerging - OLED. Although the abbreviation of Organic Light-Emitting Diode looks like xLED, it actually has nothing to do with LCD.
OLED panel TV has the advantages of self-luminescence, ultra-thin and wide viewing angle, almost infinite contrast, low power consumption, and extremely high reaction speed. The curved LCD TV imitates the biggest feature of OLED - flexibility, and it is the plagiarism of the backbone. The LCD curved telephone is ridiculed as an imitation of Dongshi Pin!
"Is the curved TV good?" - This is the most common question I hear in front of the TV counter in the home appliance mall.
After three or four years of market experience, curved LCD TV has actually entered the large-screen TV market of more than 60-inches, but the market is also filled with too many praises or criticisms, which has brought considerable trouble to consumers who hold a lot of money, for fear of being misleading.
Say 1: Curved TV is better!
Rumor degree: 0%
It is precisely because of the curved TV appearance that the curved TV looks unique and loves you. From another perspective, curved TVs are more high-end and are favored, and the superior mentality of the rich is "I bought it and you can't afford it."
Statement 2: Curved TV brings an immersive viewing
Rumor degree: 1%
Most people will not actively conclude that the latter has a more immersive feeling when experiencing pure flat-screen TV and curved TV pictures at the same time, but in fact this statement is basically correct, but there are conditions: at the same 60-inch 4K resolution, viewers of curved TV can sit closer than flat-screen TVs, thus giving a broader vision. However, when you change 60 inches to 50 inches or smaller, or try to curve the TV at FHD resolution, the above conclusion is not valid.
Say 3: The viewing effect of curved TV is the same for any distance and angle
Rumor degree: 99%
Unfortunately, this is almost a rumor. It has to be admitted that the biggest disadvantage of curved TV is that it has the "best viewing point" - the throne of the emperor (dead center). This position is the only point that can draw the above conclusion, and it is not possible to sit in a wrong place.
Think about the topic we talked about at the beginning. If the kettle is not placed on the focus of the solar stove, the water will not boil until dark. This means that it is easier for people sitting around the emperor to draw reasons why flat-screen TVs are also great.
Statement 4: The viewing angle of the curved TV is larger
Rumor degree: 50%
has been talked about before. The basic structure of the curved LCD TV (LCD, filter layer, backlight, etc.) is exactly the same as that of the flat LCD TV. Since the left and right sides of the curved surface are also close to the center of the audience, the viewing angle is correct for the audience on the "throne of emperor". But if you deviate from that sweet position or lie down incline, the rumor above will be sharply close to the top.
statement 5: The picture quality of curved LCD TV
Rumor degree: 100%
The quality of LCD TV has nothing to do with the screen shape. Whether the curved surface or not has no impact on enhancing or reducing image quality, I really think too much.
statement 6: Watching 3D on curved TV better
Rumor degree: 0%
Chat with a scientific attitude. This statement is not a rumor, it is correct. However, 3D is gradually fading out of the flat-screen TV market, and the intensity of user demand is decreasing.
If you want to stay in the middle of the night, enjoy the real emperor-like wrapping feeling when you are free to enter, then... buy a set of high-end VR equipment and come back, it will definitely meet all your needs for visual climax.
Say 7: Curved TV cannot be mounted on the wall
Rumor degree: 90%
All curved TV brands will provide additional paid wall hangers, and there is no problem installing them on the wall. But if you are more expensive and difficult than an OLED Wallpaper TV that can stick to the wall with double-sided tape as thin as wallpaper.
has another disadvantage after installation on the wall, that is, the fit between the TV and the wall feels visually inconsistent, and it doesn’t matter if you don’t mind.
Statement 8: Curved TV is more expensive
Rumor degree: 50%
First of all, the process of bending the LCD panel into curved TV is not complicated. In the early days of the rebirth of curved TV, it is also considered to charge high-end users for advertising fees and IQ tax.
In fact, the current curved TV can also be afforded. The 32-inch curved TV on the top of the East is on sale at 2XXX, but the high-end large-screen curved TV is also tens of thousands of yuan.
Although the market's impulse to agree with the beautiful appearance of curved TVs has faded, the craze for new products such as OLED and "full screen" has gradually crushed my favor for curved TVs. It turns out that the local tyrants and its steel-like enthusiasm have gradually become plastic, and a situation of high and low "curves" are seen. However, it is also unreasonable to completely deny the value of curved LCD TVs. If I had to say that the current curved TV was useless, I really couldn't agree completely!
However, after the chatter, the real surface will be placed on self-luminous OLED TVs with natural flexibility. In the future, it is estimated that the traditional screen will also be broken by a 16:9 ratio, and the future may be a special-shaped screen starting at a 21:10 ratio. At present, "full-screen" TVs are another excellent alternative.
