Multiprimary color display for liquid crystal display projectors using diffraction grating

Takeyuki Ajito Takashi Obi Masahiro Yamaguchi Nagaaki Ohyama Tokyo Institute of Technology Imaging Science and Engineering Laboratory 4259 Nagatsuta, Midori-ku Yokohama, 226-8503 Japan E-mail: [email protected] Abstract. To reproduce the natural color of an object through color imaging systems, the range of the reproducible color, i.e., the color gamut, of the color display devices must be...

Liquid Crystal Display: Environment & Technology

Liquid Crystal Display (LCD) technology has rapidly become a significant component of modern electronics. It offers solution to the rising need of low power-consuming, space-saving and better display devices thereby, paving the way for significant economic opportunities. However, the environmental impact of the end of life of the LCD products should be judiciously assessed, so that they do not ...

Dye-less color filter fabricated by roll-to-roll imprinting for liquid crystal display applications.

A diffractive grating is promising for color separation to effectively replace conventional absorptive dye color filter in liquid crystal displays. In this paper, we demonstrated a color separation module consisting of an aspheric-lenticular lens array and a blazed grating to substitute for the dye color filter. Each component was designed to match the recent fabrication ability of our roll-to-...

Detection and Visualization of Macro Defects of Color Liquid Crystal Display through Gabor Transform

This paper proposes a novel approach for detecting macro defects in color LCDs (liquid crystal displays) by using 2-D Gabor coefficients. The absolute value of the complex Gabor coefficients of an input image are used to detect macro defects such as periodic or streak patterns. The paper also proposes a new method for reconstructing images with reduced noise through linear combination of 2-D Ga...
