You may have noticed the red-tinted glass on the prior page. I wish I had confirmation of exactly what this image is and when in the manufacturing process it happens, but I suspect it might show one method of creating a color filter on the front glass. The three primary methods of creating color filters are applying foils, using a doctor blade system, or spinning a dye or pigment filter onto the glass. I think this shows the dye being deposited before being spun. However, dye spinning yields more waste than the other methods, so I have to wonder if perhaps this image comes from an older Samsung process.
