Abstract

The invention discloses a display screen structure realized by optical fibers, which relates to a display screen realized by the optical fibers and is applied in the field of high-luminance color display to solve the problems of high cost, low resolution and low luminance of the conventional high-quality display screen. An optical signal of a signal laser source of the display screen structure is input from one end of a first multimode fiber; each circulator is connected with a single mode fiber, the multimode fiber and a fiber Bragg grating to form a pixel point; N pixel points are connected end to end to form a linear structure; each pixel point outputs the optical signal with a wavelength; N is the number of the pixel points of the display screen, and is any integer in the range of 100 to 300,000,000; the N pixel points are arranged into a 10-30,000*10-10,000 array; the signal laser source is a laser which outputs N wavelengths; and the N wavelengths output by the signal laser source correspond to central wavelengths of the first to the Nth fiber Bragg gratings one to one.

Description

technical field [0001] The invention relates to a display screen structure realized by optical fiber. It is especially used in display fields requiring high brightness and color display screens. Background technique [0002] The invention and development of display screens have had a huge and far-reaching impact on the dissemination of information. The function of display screens is to display information in the form of bitmaps, such as LCD, CRT, LED, etc. Throughout the development of the display screen, the display screen has expanded from simple digital display to black and white bitmap and today's high-definition true color bitmap display, and its application fields have also been greatly expanded, and the image expression ability has also been greatly improved. [0003] Most of the display screens occupying the mainstream market today are liquid crystals and light-emitting diodes, namely LCDs and LEDs. LCD liquid crystal display is the abbreviation of Liquid Crystal D...
