Embodiment Construction

[0020] List preferred embodiment below, and in conjunction with accompanying drawing, illustrate the present invention more clearly and completely

[0021] figure 1 It is a structural schematic diagram of a laser source of an optical fiber mesh panel according to an embodiment of the present invention. like figure 1 As shown, the optical fiber grid laser light source of the present invention includes a laser 1 , a transmission optical fiber 5 , a network structure 3 braided by a diffuse optical fiber 2 that guides light throughout the body, and a fixed packaging structure 4 for the optical fiber network. The laser 1 may be a solid-state laser, a gas laser, a semiconductor laser, or a fiber laser, and the like. The laser 1 outputs laser light through a section of transmission fiber 5, and the transmission fiber 5 is connected to the dispersion fiber 2. The connection can be in the form of a standard connector, such as a plug adapter such as SMA905, or the transmission fiber 5...

Abstract

The invention discloses an optical fiber network board laser light source which comprises a laser light source body, dispersion optical fibers, a network structure and an optical fiber network fixing and encapsulating structure. The whole dispersion optical fibers can emit light. The network structure is braided by the dispersion optical fibers. The dispersion optical fibers are arranged according to size and uniformity requirements of a backlight source and a calculated special structure to form the optical fiber network which emits light uniformly, and the specially-designed encapsulating structure is used to encapsulate the braided dispersion optical fiber network into an optical fiber network board which emits light uniformly. The laser backlight source which is good in light emitting uniformity, optionally-variable in shape, low in cost and convenient in scale production, the backlight sources of current liquid crystal televisions can be replaced by the laser backlight source, low-cost laser full-color display is achieved, and the laser backlight source can be used as specially required laser lighting light source.

Description

technical field [0001] The invention belongs to the technical field of light source and laser display, and in particular relates to a laser light source of an optical fiber net plate. Background technique [0002] Traditional liquid crystal displays generally adopt the form of backlight and modulation board to realize the display of images. Backlight (BackLight) is a light source located behind the liquid crystal display (LCD), and its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). The LCD itself does not emit light, the graphics or characters it displays are the result of its modulation of the light from the backlight. [0003] At present, there are mainly three types of backlight sources: EL (Electroluminescence), CCFL (Cold Cathode Fluorescent Lamp) and LED (Light Emitting Diode). [0004] EL lamps have high luminous efficiency, low power consumption, shock resistance, and do not require maintenance. It is a cold light...
