Liquid Crystal Display Inkjet Solutions

This solution can print functional layers in different steps of LCD production and can also be used in other optoelectronic display technologies including rigid, flexible, OLED, QLED and LCD displays. In addition to outstanding micro-nano ultra-precision, this platform also meets the highest requirements for process environment and stability. For example: LGE, ISHII KYOKI, TEL and other companies specially developed technology that solves the challenges faced by the display industry for a long time and makes efficient use of high-value materials related to the manufacture of next-generation displays.

Process field

  • OLED TFE (Organic Thin Film) Encapsulation Printing
  • Printing high/low RI materials to enhance light extraction performance
  • Low K insulating layer printing
  • Printing transparent bridges (insulation) with ITO pattern and jumpers (conductive material)
  • shading layer/conversion layer/guidance layer printing
  • photoresist printing
  • RGB pixel printing
  • Micro lens printing

Solutions for RGB and TFE printing can be developed for purpose, used as stand-alone systems, or viewed as an integration of production lines including automation, pre-processing and post-processing.

Most OLED displays today are made by vacuum evaporation. They use masking technology and consume extremely expensive and large quantities of OLED material. Through the existing digital technology, the development of shading layer, evaporation, RGB and other processes in OLED can be completed by inkjet printing, which is a direct printing, mask-free, fast and cost-effective process.

Our solution was co-developed with the State Key Laboratory and includes a fully integrated print/control/ink supply/air supply/power supply/platform inkjet system solution that combines a compact design with minimized nitrogen consumption combined.

Other new inkjet systems are now being developed to develop new organic light emitting diode and QLED technologies. We have developed many OLED technologies over the years, and now it is looking to replace vapor deposition and vacuum coating with inkjet printing, which can reduce the number of steps, improve material utilization and improve display quality.
