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.
Materials used in the manufacturing process of color filters, the key component of TFT-LCD panels, include black matrix and black column spacers for the realization of vivid colors, as well as organic insulating films for the planarization ton improve the TFT performance. Through technical cooperation with Mitsubishi Chemical, we have acquired technology for in-house manufacture of organic materials for color filter manufacture, and we are focusing on strengthening our product competitiveness through millbase localization. Currently, we are working to develop organic materials for OLED.
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.
