Development and Production Status
Color-Filter of DONGWOO FINE-CHEM boasts the best production technology and quality.
Equipped with a fifth-generation color filter production line, DONGWOO FINE-CHEM differentiates itself from the competition by producing its own unique Spinless Coating technology and Photo Resist (BM, BGR, CS) needed for Color Filter.
With a glass substrate of 1,100X1,250mm and 1,100X1,300mm (15.6 in. 18 cells), we produce a range of products ranging from 2.2in mobile devices to color filters for 27-inch monitors.
Configuration of color filters
The Color Filter (C/F) substrate consists of a color-implementing C/F Pattern and R, G, and B Cells, a black matrix acting as a light barrier,
a common electrode for voltage authorization in liquid crystal cells (ITO), and a column spacer that maintains a constant gap on integration with TFT.
