Forecasting The Development Trend And Market Demand Of Polarizers In China In 2018
Jul 26, 2018
The polarizer is one of the important materials of the liquid crystal display, and is a prerequisite for the liquid crystal film to display an image. The polarizer is a composite material prepared by a process of multiple-time compounding, stretching, coating, etc. of a polyvinyl alcohol (PVA) stretched film and a cellulose acetate film (TAC), which can realize high brightness and high contrast of the liquid crystal display. characteristic. Due to its production technology, it combines polymer materials and microelectronics.
The polarizer is one of the important materials of the liquid crystal display, and is a prerequisite for the liquid crystal film to display an image. The polarizer is a composite material prepared by a process of multiple-time compounding, stretching, coating, etc. of a polyvinyl alcohol (PVA) stretched film and a cellulose acetate film (TAC), which can realize high brightness and high contrast of the liquid crystal display. characteristic. Because its production technology brings together a variety of technologies such as polymer materials, microelectronics, optoelectronics, thin films, high purity and computer control, it has a high technical content. The conventional polarizer is mainly composed of a TAC film, a PVA film, a pressure sensitive adhesive, a protective film and a release film. The TAC accounts for about 50% of the cost, and functions to support the PVA film and ensure the weather resistance of the polarizer. Usually, one TAC functional film is required for one polarizer.
Polarizer cost composition
In recent years, the global display industry has shown a growing trend, and the demand for polarizers has increased, and will further boost the TAC functional film. In 2016, the global new display panel shipment area was 202 million square meters, an increase of 8% year-on-year; domestic shipment area reached 55 million square meters, an increase of 16.5%. This growth is mainly due to the continuous increase in the demand for panels for downstream products. On the one hand, TV demand and the proportion of large-screen TVs have increased. On the other hand, the scale of products such as tablet PCs and smart phones has risen steadily, along with the average model. The increase in size and the increasing popularity of the full screen have a higher demand for screen area.

The global market for polarizers will increase from 391 million square meters in 2014 to 498.9 million square meters in 2019; capacity will increase from 588 million square meters in 2014 to 787 million square meters in 2019. It takes two TAC functional films to calculate with one polarizer. It is expected that at least 1.574 billion square meters of TAC functional film will be required in 2019.
