Want to increase your Bubble Jet IQ ? Come on over >> LCD Color Filters Liquid crystal displays (LCDs) have come into regular use not only in laptop PCs, but also in desktop models. Canon's high-precision printing technologies are at work in making these displays possible. LCDs have a sandwich structure, with liquid crystals inserted between a substrate inset with a color filter and a transistor board. The color filter is a glass plate imprinted with a matrix of the colors red, green and blue, the three primary colors. It is one of the most important components of LCDs, playing a deciding role in display quality. Canon's Bubble Jet printing technologies have been adapted for the production of LCD color filters. Previously, these devices were produced through photolithography. However, leaps in the precision of Bubble Jet printing techniques made it possible to accurately distribute ink in an area the width of human hair. Printing on a scale that allows errors no greater than the micron level is achieved by the XY stage used in a mask aligner, a device for high-precision processes in semiconductor production. The merger of these two Canon technologies helped us achieve low-cost, highquality color filters. In other words, Bubble Jet technologies are contributing to the' growth of the LCD market worldwide.  |
