   First, the development of LCD Industry Overview

TFT-LCD(thinfilmtransistor-liquidcrystaldisplay)TFT-LCD technology is a combination of microelectronic technology and liquid crystal display technology. TFT LCD is characterized by good brightness, high contrast, strong sense of hierarchy, bright colors, but there are also shortcomings of higher cost.

LCD panel used in TV mainly uses TFT LCD panel, the main components include backlight, polarizing plate, color filter film, glass substrate, film transistor, alignment film, liquid crystal and so on.


  Second, LCD industry upstream industry development status

Color filter, backlight module, polarizing plate is a key component of TFT-LCD, the key component material costs accounted for the ratio of 60%-70%, the key to control the degree of components is the key factor of each panel manufacturers to maintain competitiveness, grasp the stable sources of supply companies such as AUO, CMO, high bargaining power.

(1) glass substrate

The LCD glass substrate is a basic component of liquid crystal display device, TFT-LCD glass substrate is a thin sheet of glass surface is very smooth, the upstream raw material of the liquid crystal panel, is one of the key industries of flat-panel display materials, widely used in LCD, PC TV, notebook monitor and mobile phone field. Global TFT-LCD glass substrate supplier is Corelle of America (Coming) and Japan Asahi (AsahiGlass), electric glass (NEG) and Sn (mITechnology) 4.

(2) backlight module

The backlight module is one of the key components of the LCD panel. The function is to supply sufficient brightness and uniform distribution of light source, so that it can display the image normally. The liquid crystal display is a passive light emitting element. The display itself does not emit light, but is illuminated by the backlight system below it. The backlight and LCD display are combined to form the LCD module. The main business of the backlight module is Taiwan enterprises, mainly coretronic and radiant opto electronics.

(3) polarizing plate

The main composition of polarizing plate for TFT panel includes: TAC film (support layer), PVA film (Pian Guangceng), AG film (anti glare layer), LR/AR (low reflection / non reflection layer), PSA (adhesive layer), protective layer, WVDLC optical compensation film, which plays the role of polarizing plate preservation and transportation protection. The TAC film and PVA film are the most important films in the production of polarizing film, accounting for 54% and 17% of the cost of polarizer material respectively.

The manufacturing technology of polarizer has been monopolized by Japan, South Korea, China, Taiwan and other countries and regions. It is very difficult for mainland enterprises to produce TFT type polarizer. Local production in the field of polarizing plate is small, the main manufacturers have Sheng ophotoelectric, three spectrum, fujihoo electronics, optoelectronics, electronics Wei Xu, lucky etc..


  Third. Main application market of LCD industry

TFT-LCD can be widely used in global mobile phones, smart phones, desktop computers, laptops, tablet PCs, as well as high-definition / Ultra high-definition display, LCD-TV panels and so on.


  Fourth, LCD display competitive enterprise analysis

Key enterprises in global TFT-LCD main South Korea LGDisplay, Samsung, Taipei Innolux Corporation and AU Optronics Corp., Japan and JapanDisplay, the BOE Technology Group Co. in recent years, the fast growth of business.

   Fifth, LCD display industry market trends

LCD monitor market is mature, brand manufacturers turn to higher product line development, in which the trend of large size is obvious. In 2015 Chinese Internet market on 32 inch LCD monitor demand continues to expand, because new capacity continues to open the panel sources without fear, while the 32 inch TV panel prices fell, the price is far lower than the current Internet panel module market mainstream 27 inch, so many brands of factory to get a TV panel made of 32 inch LCD monitor, which monitors shipment growth significant.

In 2015, the total output of LCD TV was 215 million units, with an annual recession of 0.6%. After 2013, the year of LCD TV shipments fell again. In 2016, the Fed announced that the impact of rising interest rates on the vulnerable currencies will continue to expand, thereby affecting the purchasing power, which may directly affect the 2016 TV shipments. On the other hand, the recent decline in panel prices will help the whole machine profit, such as brand manufacturers will spread the price reaction on the whole machine price, is expected to drive a new round of sales in the busy season; and the larger size of the TV price is more popular, helping small size upgrade demand for large size. LCD TV shipments are expected to be 222 million units in 2016, an increase of 3.3%.

In the long term, the market structure of the industry changes less, and its market segments, the future of TFT-LCD in the car display and wearable device market prospects. But generally speaking, at present, South Korea has LGDisplay shift to OLED, Samsung also in quantum dots R & D integration OLED technology development, new TV, plus laser TV technology can be seen, whether it is television or mobile, LCD technology, living space is compressed, no longer brilliant prospects.
