polarizer
polarizer accounts for about 11% of the cost of LCD panels. It is also the main material and one of the most difficult areas for domestic production of LCD panel technology in my country. The polarizer is located on both sides of the LCD panel. By transmitting or blocking the light emitted in backlight module , adjusting the brightness of the pixels and reproducing the color, so that the human eye can see the bright colored display image. Without it, the LCD panel cannot be displayed.
From the picture, it can be seen that there are two companies in China, Sanlipu and Shengbo Optoelectronics, and Japan and South Korea occupy a leading position.

color filter
color filter is one of the most expensive parts of the LCD panel.
Most of the LCD panel manufacturers in the industry make color filters. For example, Samsung's homemade ratio is 75%, while Chime and LGD's homemade ratio is as high as more than 90%. Manufacturers such as BOE and Tianma also have their own color filter factories, but the homemade ratio is not as good as South Korea and Taiwan. About 70% of them need to be imported, mainly because the import sources are Japanese letterpress printing, Japanese ink (DNP), and Toray Corporation (TORAY). The domestic production of
color filters is also quite gratifying. First of all, major domestic panel manufacturers are constantly increasing the proportion of self-produced color filters. While domestic LCD panel sales continue to increase, the domestic demand for purchasing color filters is constantly decreasing, which is the result of the continuous increase in the proportion of self-produced.
In addition, in the field of professional outsourcing, the leading company Dongxu Optoelectronics in China was mainly led by leading company Dongxu Optoelectronics. In 2015, it has invested 3 billion yuan to invest in color filter production lines. It has introduced the technology and production line technology of Japan DNP. DNP even transferred its only fifth-generation TFT-LCD color filter production line to Dongxu Optoelectronics as a whole, and its Chinese market share will also be transferred to Dongxu Optoelectronics. Dongxu Optoelectronics color filter customers have been fixed to domestic Longteng Optoelectronics and BOE, and will start mass production in the first quarter of this year.
According to the "Strategic Cooperation Agreement" signed by Dongxu Optoelectronics and Longteng Optoelectronics, only one fifth-generation TFT-LCD panel production line of Longteng Optoelectronics can digest more than 70% of the production capacity of Dongxu Optoelectronics' 5th-generation color filter production line.
From Dongxu Optoelectronics' large-scale investment, we know that the benefits of my country's expansion of its share in the LCD panel field are definitely difficult to enter the supply chain of LCD panels in Japan, South Korea and Taiwan, and it is much easier to enter the supply chain of domestic panels.
However, we must see that although the share is increasing and leading companies are also investing heavily, we must also see that the import ratio of large domestic manufacturers such as BOE and Tianma is still above 70%. Moreover, the line that Dongxu Optoelectronics put into production in the first quarter of this year is only the fifth generation line, and the color filters that are equipped with high-generations are still blank.
mixed liquid material
mixed liquid crystal material is the basic material of liquid crystal panels that is crucial to the performance of liquid crystal panels.
There is a liquid crystal material company in my country that ranks third in the world in terms of sales, with a domestic market share of up to 65%. However, please note that LCD includes a variety of low-end black and white screens can be LCDs. Chengzhi Yonghua mainly has the advantage of black and white LCD screens.
, and the high-end TFT LCD materials used in smartphones and TVs, Germany Merck, Japan Chisso and Japan DIC, monopolize the TFT LCD market, with a total global market share of more than 90%. It can be said that these three companies monopolize the global market.
my country mainly includes Chengzhi Yonghua and Jiangsu Hecheng, which can supply TFT hybrid LCDs to LCD panel factories. In addition, there is an 800 million LCD that has emerged, becoming BOE's domestic first LCD supplier in 2017.
In 2016, the global demand for TFT liquid crystal materials was around 700 tons. The overall sales of mainland liquid crystal material manufacturers is expected to be around 40 tons, accounting for 5.7% of the world. In 2015, mainland liquid crystal material manufacturers shipped only 27 tons. In other words, China's local LCD material shipments increased by as high as 50% in 2016, far higher than the global development speed. Compared with
, the global TFT liquid crystal material shipments were 600 tons in 2013 and 700 tons in 2016, with a three-year increase of only about 16%. Domestic TFT LCD material manufacturers basically supply domestic LCD panel manufacturers. Therefore, it is expected that in the next 10 years, domestic LCD materials will grow significantly under the leadership of domestic brands.
Take Hecheng Display as an example. The operating income in 2016 was 385 million yuan, an increase of 73.76% over the same period last year; the net profit attributable to shareholders of listed companies was 79.3833 million yuan, an increase of 91.41% over the same period last year
backlight
backlight module is the most expensive part of the display panel, accounting for about 20% of the cost, but the technical difficulty is not high and it is a labor-intensive industry. Most of the backlight modules in the world are produced in my country.
However, about 60% of the cost of the backlight module comes from optical films, mainly including diffusion films, reflective films, , brightening films, etc. The domestic production progress in this regard is not bad, and the development speed is very fast.
Take optical reflective films as an example. Ningbo Changyang Technology has shown an extremely high growth rate. Its revenue was 149 million in 2014, 250 million in 2015, and 400 million in 2016. The world share of large-sized reflective films used in LCD TVs and other products has reached 35%, ranking first in the world, surpassing Japan's Toray and Teijin.
Ningbo Jizhi Technology, which focuses on diffusion films, reflective films and brightening films in China, has grown rapidly. It has maintained an annual growth rate of 30% from 2014 to 2016, and its share is continuing to expand. According to the financial report released by Jizhi Technology in February 2017, its operating income in 2016 was 613 million yuan, an increase of 29.79%, and its net profit was 63.49 million yuan, an increase of 10.75%.
optical film domestically produced Kangdexin is the leading and is already one of the world's largest optical film manufacturers. According to the financial report released by Kangdexin in 2017, the annual revenue was RMB 9.225 billion, an increase of 22%, and the net profit was RMB 1.978 billion, an increase of 37.47%. Kangdexin is a multi-business group, and its revenue from optical films accounts for about 70%.
However, domestic materials need to continue to work harder for more upstream materials. The main raw material for the production of these optical films is optical base film. To produce optical films, optical base films must be purchased. At present, in terms of optical base films, more than 80% of the global production capacity is monopolized by several major giants such as Mitsubishi Resin, Toray, Teijin, DuPont , Kelong, SKC, and Toyo String. Domestic manufacturers include Lekai Group , Kangdexin, Yuxing Co., Ltd. , Nanyang Technology (Dongxucheng Chemical), etc.
After Kangdexin grew rapidly in the field of optical films, it also began to develop its own optical base films. Kangdexin started construction of the second phase of the optical film 100 million square meters polymer material factory in April 2016, including the optical base film project, and is expected to maintain rapid growth in the future.
optical base film requires PET film (polyester film) slices as substrate, while Display Research estimates that the global demand in 2016 was 360,000 tons. Kangdexin, which is currently growing rapidly, has a production capacity of about 50,000 tons, and is equipped with its own optical film production.
In addition, Nanyang Technology Company released its 2016 financial report, the company achieved operating income of 1.235 billion yuan, a year-on-year increase of 33.73%; net profit attributable to shareholders of listed companies was 120 million yuan, a year-on-year increase of 20.3%. Nanyang Technology Company said that the main reason for the increase in operating revenue by 33.73% is the start of the company's "annual output of 20,000 tons of optical grade polyester film project".
driver IC
This is a relatively weak field in my country. Currently, driver ICs are mainly Japanese Renesas; Korean Samsung is mainly self-produced and sold; panel driver ICs in mainland China mainly come from Taiwanese manufacturers, including Lianyong, Morningstar, Duntai; domestic ones include Xinxiangwei and Gekewei.

type of screen
screen type: STN, TFT, TFD, UFB, OLED, ASV
【STN (Super Twisted Nematic) Screen】, also known as the super-twisted nematic LCD display screen. A color filter is added to a traditional monochrome liquid crystal display, and each pixel in the monochrome display matrix is divided into three pixels. The three primary colors of red, green and blue are displayed through the color filter respectively, so as to achieve the function of displaying colors, with the main colors of light green and orange. STN screens are reflective LCDs, which have a low power consumption but poor clarity in darker environments.
[TFT (Thin Film Transistor) is a thin film field effect transistor] , which is one of the active matrix liquid crystal displays. It can "actively" control individual pixels on the screen, which can greatly improve the reaction time. Generally, the reaction time of TFT is relatively fast, about 80 milliseconds, and the viewing angle is large, generally reaching about 130 degrees, and is mainly used in high-end products. The so-called thin-film field effect transistor means that each liquid crystal pixel point on a liquid crystal display is driven by a thin-film transistor integrated thereafter.
[TFD (Thin Film Diode) screen] , also known as thin film diode semi-transparent liquid crystal display. TFD technology was developed by Seiko and Epson and is specially used on mobile phone screens. It is a tradeoff between TFT and STN, better brightness and color saturation than STN, and also saves power than TFT.The biggest feature is that it can provide high image quality and easy-to-see display regardless of whether it is turned off (reflection mode) or turned on (transmission mode), and has the advantages of low power consumption, high image quality, and high reaction speed.
[UFB LCD] is a new LCD display device for mobile phones released by Samsung in March 2002, with ultra-thin and high brightness. UFB-LCD is a display specially designed for mobile phones and PDAs. It has ultra-thin and high brightness features, displaying 65536 colors and reaching a resolution of 128x160. The display also uses a special grating design that reduces pixel spacing for better image quality. The contrast ratio of UFB LCD screen is twice that of STN LCD screen. Its brightness is comparable to that of TFT screen in 65536 colors, and its power consumption is less than that of TFT screen, and its price is similar to that of STN screen. It can be said that it combines the advantages of these two existing products in one.
【OLED (Organic Light Emitting Display)】 is an organic light-emitting display. It is a new product on mobile phone LCDs and is known as a "dream display". OLED display technology is different from traditional LCD display methods. It does not require a backlight and uses a very thin organic material coating and glass substrate. When an electric current passes through
, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, with a larger viewing angle, and can significantly save power consumption. Currently, among the two major OLED technology systems, low-molecular OLED technology is mastered by Japan, while polymer PLED (the so-called OEL of LG mobile phones is the product of this system) is mastered by British technology company CDT. Compared with the two, there are still some difficulties in colorizing the PLED products.
【ASV (Advanced Super View)】 technology is another breakthrough in SHARP in LCD panel production technology. This technology is mainly used in LCD displays positioned in SHARP’s high-end market. This technology mainly improves the viewing angle of the LCD screen, the reaction time of the LCD particles, the color contrast and screen brightness of the LCD screen. Compared with the same screen area, screens that use ASV technology can have an essential improvement in parameters and effects compared to ordinary LCD displays that do not use ASV technology. For example, the T1520, T1620, T1820 and other series models are obviously advantageous in terms of parameters and effects compared with those of the same screen size level on the market.
Summary:
STN was the main device of early color screens. It could only display 256 colors at first. Although it could display 4096 colors or even 65536 colors after technical transformation, the general STN is still 256 colors now. The advantages are: low price and low energy consumption.
TFT has good brightness, high contrast, strong sense of layering, and bright colors. The disadvantage is that it consumes more electricity and has a higher cost.
UFB is a display specially designed for mobile phones and PDAs. Its characteristics are: ultra-thin and high brightness. 65536 colors can be displayed, and the resolution can reach a resolution of 128×160. The UFB display adopts a special grating design, which can reduce pixel spacing and achieve better picture quality. UFB combines the advantages of STN and TFT: it consumes less power than TFT, and the price is similar to STN.
If the display effect is arranged from high to low, it is ASV>TFT>OLED>TFD>UFB>STN>CSTN

【STN (Super Twisted Nematic) Screen】, also known as the super-twisted nematic LCD display screen. A color filter is added to a traditional monochrome liquid crystal display, and each pixel in the monochrome display matrix is divided into three pixels.
