In the field of TFT-LCD products, TV is still the most important product that consumes LCD capacity and area.AVC data shows that from January to June 2021, the global LCD TV panel shipment area was 85 million square meters, a year-on-year increase of 9.3%.In addition, IT panels, commercial displays, as well as vehicle-mounted displays, industrial control displays, VR/AR equipment, and medical displays are developing rapidly.In terms of technology research and development, ultra-large size, ultra-thinning, high contrast, and wide viewing angle have become the exploration directions, and it is necessary to continue to optimize product structure and develop high value-added products.It is understood that in the field of large size, Shanjin Optoelectronics has developed and mass-produced BD Cell rainbow pattern improved polarizers for TV and QWP structured polarizers for outdoor use, improving the optical level of VA high-transmittance polarizers for TV display, and promoting TV display. Product development process with an ultra-wide perspective.In the field of small and medium-sized products, technologies such as ultra-thin display product technology and special-shaped product customization are constantly being upgraded, and ultra-thin products are about to be mass-produced.
