Blue pigments is a key component in color liquid crystal display (LCD) screens. An LCD screen is in fact made up of little cells known as pixels. Each cell contains blue, red and green pigments, which act as filters: the energy passing through them combines with them to create millions of different colors. These pigments need to be ultra-pure, very fine, resistant and able to spread evenly over the screen surface. A better quality pigment gives a picture that is not only more brilliant and more luminous, but also higher definition.
