Who is the smart TV screen better? The top five manufacturers sign panel technology inventory

The ever-increasing use demand of users has led to the rapid development of the television display industry. Numerous display technologies and panel technologies have emerged in front of users. Whose smart TV screen is better? With the increasing sales of smart TV products, the electronic display technology of smart TVs is also getting higher and higher. The major panel makers also use their own unique methods to bring signboard technology. Below, Xiaobian brings a large inventory of five major manufacturers' panel technology to help users better purchase smart TVs.

Smart TV Who's Better Five Manufacturers Sign Panel Technology Inventory

First of all, to give everyone a little knowledge, as the two main uses of the display panel, one is as a TV panel, the other is our usual computer monitors, according to different needs, and use occasions, these two main uses of the display The panel also has relatively different requirements. The television is mainly used as a program for viewing purposes, so there is a higher requirement for the panel's color rendering and dynamic image display capabilities. This is also the reason why the color gamut of a television is generally higher than that of a display.

LCD panel

There are many differences between computer monitors and TV panels. According to different use environments, there are different requirements for computer monitor panels. For example, monitors used for graphs will maintain a relatively accurate display panel color gamut. However, they do not want to be as rich in TV panels as they are to better restore the quality of cartographic qualities. If they are used in professional gaming competitions, the response to display panels, tearing of quality, and dynamic display capabilities are all There are very high demands.

Display knowledge Small popularity Part of representative panel types

Now the screen panel can be broadly divided into two kinds: soft and hard. Let's talk about the soft screen first. The so-called soft screen is the LCD panel that does not use the protective film. Including TN, PVA, MVA, etc. The panel is a soft screen. The prominent feature of the soft screen is that pressing on the screen body by hand will cause “water ripple phenomenon” to disappear after a while, but it will not affect the image quality. .

Hard screen soft screen difference

The hard screen is to add a layer of transparent resin material on the LCD panel to protect the outer film. The hard-screen process was initially promoted by Japanese companies such as Hitachi. Later, LG made substantial improvements to the technology and formed a very distinctive S-IPS hard-screen process technology. The prominent feature of the hard screen is that the screen has a certain degree of stability. With the finger gently squatting on it, no obvious shadows will appear, which is good for screen protection, but the paste process must be good enough. The main representative of the hard screen manufacturers is LG-Philips, LCD TVs such as LG, Toshiba, Hitachi and other manufacturers also use hard screen.

IPS screen has more advantages than VA screen reality

Our current display device body is such a variety of screen types, and the corresponding screen panel also has its major manufacturers. Next, we will introduce the current civilian market, mainstream panel manufacturers and their own unique technologies, each panel. I will list one vendor and give a detailed introduction to everyone. The following analysis is in no particular order.

LG Display Gold Display

LG Display: It is currently the world's No. 1 LCD panel manufacturer, and is a subsidiary of the LG Group. It is headquartered in Seoul, South Korea and has R&D, production and trading organizations in Korea, China, the United States, Japan and Europe.

LG Display

LG Display's customers include Apple, HP, DELL, SONY, Toshiba, PHILIPS, Lenovo, Acer, and other world-class consumer electronics manufacturers, Apple's iPhone 4, iPhone 4S, iPhone 5, iPad, iPad 2, The New iPad and The latest iPad mini adopts LG Display's LCD panel.

LG Display

In 2012, LG Display produced a large-size TFT-LCD with a 9.1-inch or above market share of 29%, ranking first in the world. According to the product category, LG Display has a market share of 24.6% in the LCD TV market, 33.3% in the LCD market for notebook computers, and 28.2% in the LCD market for displays. With the market share of 39.4% recorded in the LCD industry, the market share of the main products is the highest in the world. LG Display is currently the leader in display panel manufacturers. What representative technology does it have?

OLED

To say that LGD's current major technology, it should be regarded as now popular OLED technology, LG Display is very optimistic about the prospects of OLED technology, even that OLED will replace the current LCD display technology, is a well-deserved next-generation display technology, and OLED technology has invested a lot of R & D funds and personnel efforts, and now the most important OLED manufacturer on the market is LG Display.

OLED TV

So what is OLED? OLED is called Organic Light Emitting Diode. It is also called organic electro-laser display and organic light-emitting semiconductor. With the liquid crystal display is a different type of light-emitting principle. OLED was discovered by the American-American professor Deng Qingyun in the laboratory in 1983, and the OLED research was started. OLED display technology has advantages such as self-luminescence, wide viewing angle, almost infinite contrast, lower power consumption, and extremely high reaction speed. However, in the price (larger display panel), life, temporarily unable to match with the LCD monitor.

OLED display panel structure

The theoretical cost of OLED is lower than that of LCD TVs, but our current technology still has flaws, which makes the yield of OLED screens relatively low at the time of cutting. It has to be said that if OLED solves the problem of life and yield, It will be a very mature display technology. As for whether it can compete with LCD technology, I still have reservations. Many people think that the prospect of OLED will be much better than LCD, but I do not think so. Why? And listen to me down the analysis.

LCD panel counterattack Samsung lead quantum dot technology

As the world’s leading manufacturer of TV product lines, it is also one of the largest LCD panel manufacturers in the world. Samsung’s TV products have always been based on its excellent design as the selling point of products, and it is also the endorsement of the highest technology of civilian-grade TV on the market. One of them, each of its flagship products will lead the market trend, in the TV market has always been a very high status and right to speak.

Samsung SUHD TV

Samsung's own display panel technology is very large, here is still the OLED as an entry point, in fact, Samsung is one of the first manufacturers to study OLED, but Samsung in recent years did not value this technology as LG Display, Samsung may not think that OLED In the short term, it can be developed to suit its own profit point. So compared to OLED technology, Samsung seems to be more optimistic about another LCD technology: quantum dot display technology.

Samsung's second-generation quantum dot TV shows amazing results

What is quantum dot display technology? Quantum dot light-emitting diodes, scientists from the United States, South Korea, and Belgium will work together to develop an active-matrix display based on quantum dot light-emitting diodes (QLEDs). Compared with the current display screen, the new display screen greatly reduces the energy consumption while greatly improving the brightness and vividness of the screen. It looks beautiful, but QD luminescent materials cannot be separated from LED technology at this stage. QLED is still a quantum dot for LED luminescence, and there is still a certain distance compared to OLED's self-illuminated black field performance. Relative product yield, and life expectancy are very large relative to OLED.

Samsung SUHD TV

The current QLEDs and OLEDs are still in their own right. It is difficult to say who will be able to "hit" on display performance. However, the current quantum dot display technology and OLED are still in a very preliminary stage. It is said that there are already researchers. Quantum dot self-emission technology has been discovered. Currently, this technology is also under development. It may still be a while before the OLED is widely used. However, the quantum dot self-luminescence can be enhanced according to its own natural advantages compared to the brightness of the OLED panel. The quantum dots of the backlight technology believe that the performance on the black field will also be excellent. This is why the author is more optimistic about the quantum dot technology. Of course, we can not be partial, OLED display and quantum dot display technology are very development. potential.

Display panel old giant AUO AUO

AUO Optoelectronics Co., Ltd., formerly known as Darwin Technology, was established in August 1996. In 2001, it merged with Lianyou Optoelectronics and changed its name to AU Optronics. In 2006, it re-acquired Guanghui Electronics. After two mergers, AUO has been able to produce all generations of production lines that produce large, medium, and small sized panels. AU Optronics is also the world's first TFT-LCD design, manufacturing and R&D company publicly listed on the New York Stock Exchange (NYSE). AU Optronics also plays an important role in the display industry.

AUO

AUO's own home technology is very mature, this is a relatively stable and stable company, only when the technology is relatively mature will be put on the market, AUO is more representative of its own MVA Panel, AU Optronics as a Sony partner, Sony is one of the main customers of AUO, Sony has an impressive chip and display control technology, AUO has excellent display panel, powerful combination also created a Sony In the display industry aloof.

In 2015, Innolux and AUO announced the acquisition. Innolux and AU Optronics, formerly known as the Panel's Dual Tiger, fell in love this year. Haha, from 2014 to 2015, was a disaster for display panel makers. In the past year, due to the market downturn, Chi Mei sold itself, Innolux, and AUO have also paid for their own protection fees. Next, we will talk about Innolux.

Display giant Innolux at Foxconn Industrial Park

Innolux is a TFT-LCD panel manufacturing company founded by Foxconn Technology Group, which ranked first in China's foreign exchange earnings in 2002. Innolux has a one-stop approach to production and sales operations, providing a total solution for the group's customers. Since its establishment, Innolux has attached great importance to the development of new products. Mobile phones, portable, car DVDs, digital cameras, game consoles, PDA LCD screens and other star products have been put into mass production, and they have quickly seized the market and won market opportunities. As of April 2004, 90 patents have been obtained.

Innolux

Innolux, one of the industry’s two-fingered panel makers, was more innovative than its brother AU Optronics. In 2009, Chime Electronic was established in 1998 after the financial turmoil. Has not been able to breathe, in the event of bankruptcy, Foxconn's Innolux adopts a share swap way to merge large LCD panel maker Taiwan Chi Mei Electronics. Then came the merger with Nanjing Tongbao Optoelectronics Co., Ltd., which formally merged in May 2010 to form a new company, still called CMO, but the surviving company is Innolux. The company's management rights were taken over by the original Innolux's management team. The general manager was Duan Xingjian, the general manager of the original group, and the former general manager Wang Zhichao transferred to Nanke and was responsible for Nanke's TFT; the three-in-one case was officially announced.

Chi Mei Electronics

Sources said Innolux is building a new 6-generation LTPS line, which will have a monthly production capacity of approximately 23,000 substrates, and will produce both LCD and AMOLED panels. Innolux expects that the new production line will start producing panels in the first half of 2016. As early as 2012, Innolux has promised to produce small OLED panels, but this plan has not been implemented. Later, Innolux shifted its focus to 4K technology. Innolux owns a 3.5-generation IGZO plant in Tainan, which is mainly used for research and development. Innolux's prototype AM OLED panel has been using the WRGB architecture. The architecture of the white RGB is still different from that of the red, green and blue tri-color OLEDs. The display performance still needs to be slightly inferior.

Sharp father of panel still has advantages

Sharp Corporation is a Japanese electrical and electronics company. Founded in 1912 by the founder Hiroshi Tokugawa, the head office is located in Osaka, Japan. Since Sharp launched its business from radio and solar cells to liquid crystal displays, Sharp has launched several "first in Japan" and "first in the world" products. At present, Sharp is now operating in 26 countries and 64 regions in the world. It is a large-scale integrated electronic information company.

Sharp

In February 2016, Sharp Corporation of Japan agreed to the acquisition offer made by Foxconn Corporation of Taiwan. This is the largest acquisition of overseas companies that Japanese technology companies have ever received. This means that Foxconn will invest more than 650 billion yen in Sharp. Sharp's board of directors passed the acquisition agreement unanimously.

Hon Hai Group acquires Sharp

As the maker of the world's first LCD panel, Sharp has been tepid in the display panel area in recent years, but anyone can not ignore its aloof position in the field of display panels. Technology, Sharp is there, Sharp's panel screen technology has always been in the world's leading position, with the broadcast infrastructure quickly switching from analog to digital, LCD TV as the main digital image entertainment TV in the new century, the world's demand growth Very quickly, it is perfectly suitable for digital broadcasting, not only beyond the limits of the traditional screen size, but also rapidly improving the quality and performance of the viewing quality such as image display and viewing angle.

Sharp TV

The ambitious Sharp company has high hopes for LCD TVs. With its technical advantages, Sharp not only has to win peers, but also tries to take share from plasma makers. The birth of AQUOS has been devoted to opening up new markets. It is a good proof that the name AQUOS comes from the combination of the English word “aqua” and “quality” and refers to the images brought by the liquid crystal material flow.

Sharp ASV technology: ASV LCD panel, ASV technology is characterized by the original spherical pixels, true color reproduction, the overall tone is reddish, and the viewing angle is large. However, it is not possible to distinguish ASV panels by pixel alone, because Sharp has already exported the technology to panel makers in Taiwan. It is difficult to see the panel produced by Taiwan's ASV LCD panel and Sharp Kameyama plant in Taiwan. difference.

Write last

We can basically see that the display panel market in the next few years will be the world of Quantum Dot TV and OLED TV. There is also a kind of laser projection technology. At present, there is no other manufacturer other than Hisense. The display technology has continued research and development, so I speculated that in a short time, laser projection technology and QD and OLED can not compete. However, if the equivalent sub-point technology can achieve the current estimates of some manufacturers, become self-luminous materials, in all aspects, will be relatively more display than the OLED is much stronger.
