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 isinput 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 connectedend 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 100to 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.
