BUILDING A BETTER FUTURE THROUGH CONVERGENCE
Soulbrain’s Display Materials Division is providing a stable supply of high-tech chemical materials and parts, and we are leading the development of the display industry through development of products leading changes in the process. We are domestically manufacturing functional chemical materials used in the manufacture of LCD and OLED panels, as well as key components of panels including thin glass and cell scribing.
Etchants for display chemically or electrochemically etch metals and non-metal materials, and are used in the process of wire formation for LCD and OLED displays. In the case of the LCD industry, etchants are made up of Ammonium-based (H2O2) etchants mainly used for the etching of copper wiring, oxalic acid-based etchants for etching ITO, BOE-based etchants for etching Si-based thin films, and so on. In particular, there is increasing demand for functional etchants achieving goals such as process ability improvement through price reduction.
We mass-produce and develop materials for OLED and color filter materials, which are core components of TFT-LCD panels. Materials for LCD include Black Matrix for the clarification of colors, Black Column Spacer, and organic insulating film for flattening, while materials for OLED include QD Bank for the INKJET process, Black Pixel Define Layer for anti-reflection, and others. In partnership with Mitsubishi Chemical, we are securing our own technology and product competitiveness through mill Mill-base localization.
In the process of OLED panel manufacture, through our efforts for stable supply and our independant technologies for Thin Glass, making the front and back glass substrates thin, and for the scribing process which cuts each panel into individual cells, we provide our customers with a one-stop solution. By introducing the vertical spray method into the slimming process, we have greatly improved the productivity and quality of our products, with the characteritic of allowing selective etching of the front glass through employment of various masking technologies.
