Domestic color TV makers "blast" curved LED

The technical dispute in the color TV industry once again filled with a strong smell of smoke.

"Curface LCD TV is a step backward in the color TV industry." A few days ago, Liu Weizhi, the president of the color TV division of Skyworth Group, spearheaded the curved LED. He said that it not only failed to bring about a new user experience, but also increased the cost of the company and gave it to consumers. Added burden. "Curved LED is a transitional product." The home appliance industry also believes that the current curved surface LCD is "surface curved surface", due to its own defects, the life cycle will not be long.

Surface LCD industry is backwards?

At the same time as Skyworth GLED Air was released, domestic color TV makers for the first time "cursed" on curved LCD TVs.

"From the point of product weight, thickness, viewing angle, brightness and other product angles, or from the perspective of cost, environmental protection, etc., curved LED TVs do not meet the current trend of the color TV market." Liu Yizhi said, the thinnest thickness of curved LED It is 33mm and weighs 20.2kg. Compared with GLED, the body and weight are 3 times and 1 times higher respectively.

In addition, the LED is made to be "curved", which not only makes it difficult to explode the screen during baking, but also easily leaks light over a large area, and the viewing angle is less than 76 degrees. "The surface LED's thickness is 1 times thicker than the same size LCD flat panel TV's, and the packaging is 1 times larger, which leads to 1 times more expensive transportation cost. Moreover, the fixtures on the production line must be completely adjusted, which increases the company's production cost, but does not bring good results to users. The experience will bring about a price burden.” Liu Zhizhi stated that the curved LCD TV is a countercurrent to the trend and it is necessary to bring color TV manufacturers to the pit. Only the OLED technology can really do curved screens.

Overall less than 5%

"Surface LCD is almost rising with the advent of OLED." Yesterday, Nanjing, a store color TV official said that at present, the sales of curved TV is divided into two camps, one is OLED, and then the surface LED.

"The curved surface is only a feature of 'fabric embellishment' for domestic color TV sets." The person in charge told the reporter that although brands such as Hisense and TCL have some layouts, they are only individual models, which account for a very small proportion. "Even if it is a joint-venture color TV brand like Samsung, LG, etc., the proportion of curved-surface TVs will not exceed 30%."

According to its introduction, because the selling price is at least 10% higher than flat-panel TVs of the same size and size, the sales of curved-surface TVs are not high. "Including curved OLEDs and curved LEDs, the overall ratio is between 3% and 5%."

However, statistics from Samsung Electronics indicate that Samsung TV won more than 30% of the global TV market share in the first half of this year thanks to the strong push of curved TV.

Leaving the "Emperor" effect is even worse

The birth of curved LCD TVs is thought to be inspired by OLED's "reelable". Liu Buchen, a senior observer in the home appliance industry, believes that curved LED is more inclined to transitional products due to various birth defects.

"The surface of the TV screen has its own advantages. The screen is curved in a certain arc, which achieves the same distance between all the image points of the screen and the center of the audience. This can reduce the distortion of the screen at the edges of the screen." Liu Buchen thinks, but to realize the curved surface TV The high fidelity of the picture must be based on the premise that the audience must sit on the "Emperor". “Once the television screen has a curved surface, the best place to watch TV is the 'Emperor', and there is only one place. Once out of this position, the effect of watching TV is not only inferior to flat-screen TVs, but may even be worse. It's easy to distort."

Liu Buchen analyzed that the reality of people watching TV is, however, that "where they are sitting" has great arbitrariness. "This proves from another point of view that the 'curved surface' curved surface TV is of little practical use."

Quantum TV is robbed of high gamut to become a new TV selling point

Before Samsung demonstrated Quantum Dot TV at CES 2015, TCL Multimedia took the lead in stimulating quantum dot TV in the Chinese market.

According to the reporter, behind the concept of "quantum dots," the high color gamut (ie more colorful colors) will become the latest selling point in the TV field in 2015.

Quantum dots, the English name Quantum Dot, is a very advanced nanomaterial with a crystal grain diameter of between 2 and 10 nanometers. The quantum dot has a unique photoelectric property. It is stimulated by electricity or light and will be based on quantum dots. Diameter size, emitting a very pure high-quality monochromatic light of various colors.

According to Chen Guanglang, chief technology officer of TCL Multimedia and general manager of the global R&D center, QD TV can reach 110% color gamut, which is not inferior to OLED, which is called next-generation display technology.

In fact, in addition to TCL, color TV operators are eyeing QD TVs - Samsung and LG are all planning to launch QD TVs at CES in 2015. Hisense is also active in quantum dot technology. It is reported that its future will be In cooperation with 3M, QD backlight TVs are being deployed. In addition, TV companies such as Changhong have continued to follow suit.

TCL Multimedia CEO Hao Yi said that compared with OLED, quantum dot TV is a product that can be popularized, and its picture quality is not lost to OLED TV.

According to its introduction, TCL’s first quantum dot TV is positioned in the high-end market, but its price is lower than the domestic same-size OLED, and the average consumer demands more and more color on the TV screen, so quantum dot TV may soon Into the mass market.
