SYSTEM OF LIQUID CRYSTAL DISPLAY HIGHLIGHT AND DISPLAY THAT CONTAINS IT Russian patent published in 2009 - IPC G02F1/13357 G09G3/36 

FIELD: physics, optics.

SUBSTANCE: invention is related to the field of optics and facilities of information displaying, and may be used for highlight of colour liquid-crystal (LC) displays and creation of LC displays that do not contain matrix of colour filters. In matrix LC display and its highlight system, which contains the following serially installed components: one or more light sources, light-conducting layer, array of light-outputting elements, fiber-optic plate installed between array of light-outputting elements and LC display, foresaid fiber-optic plate represents matrix of elements made with the possibility of light source radiation spectrum transformation into radiation with wave length that corresponds to colour formed by subpixel of liquid crystal display, at that size and location of mentioned elements correspond to size and location of liquid crystal display subpixels, at that the first line of matrix of elements that transform wave length, is installed opposite to the first line of liquid crystal display, the second line of matrix of elements that transform wave length, is located opposite to the second matrix of liquid crystal display, n line of matrix of elements that transform wave length is installed opposite to n line of liquid crystal display matrix, at that every element of foresaid fiber-optic plate contains at least one photon-crystalline fiber, which transforms wave length, at that mentioned fibers are tightly packed and completely fill area of mentioned element, at that photon-crystalline fiber includes set of fibers with hollow core that are installed lengthwise around hollow or solid wave conductor area, at that fibers with hollow core are installed so that create two-dimensional photon crystal with photon prohibited zone, at that mentioned hollow or solid wave conducting area is formed to transmit signal with frequency that lies mostly inside photon prohibited area, so that light source radiation spectrum is transformed into radiation with length of wave that corresponds to colour formed by subpixel of liquid crystal display.

EFFECT: creation of LC display highlight system with improved efficiency of light source radiation application and application of radiation source of only one type, and also creation of LC display with high transmission, in which suggested highlight system is used.
