Embodiment 1
[0023] The reflector and fluorescent sheet mentioned in Embodiment 1 should be respectively installed at positions A and B on the small reflector 6, so that the light can fully enter the light guide plate, and the relative position between the reflective mirror and the fluorescent sheet can be maintained ,See figure 2 ;
Embodiment 2
[0024] The situation after the small reflector mentioned in embodiment 2 is added to the whole backlight module, see image 3 , which is the overall shape structure, the bundled optical fiber 2 and the small reflector 6 are fixed on the connecting plate 5, which can ensure the integrity, and after a certain package, can ensure the overall stability.

The invention provides an LD coupling bundled optical fiber reflection type backlight module. A bundled optical fiber comprises an incidence end and an emergence end. Multiple optical fibers with the lengths changing in an arithmetic progression mode are separated from the emergence end. A blue light LD is connected with the incidence end of the bundled optical fiber, and blue light irradiated by the blue light LD is coupled through a shaping prism and a focusing mirror to enter the bundled optical fiber and is transmitted to the emergence end of the bundled optical fiber. The optical fibers with the lengths changing in the arithmetic progression mode are arranged in a gradient mode, and all small reflecting covers correspond to all the optical fibers. The small reflecting covers control the directions of output light, and the light can better enter a light guide plate. The LD coupling bundled optical fiber reflection type backlight module is simple in structure, small in size, low in weight and compact in structure, and has the advantages of being low in equipment investment, simple in production process and high in product yield.
Description
technical field [0001] The invention relates to a backlight module structure, in particular to a backlight module structure of LD coupling bundled optical fibers. Background technique [0002] Laser display has the advantages of large color gamut, high color saturation, energy saving and environmental protection, and long life. It is considered to be a new generation of display technology after black and white, color, and digital high-definition. In terms of laser display, there are many researches on laser projection display technology, which is relatively mature; there are few researches on laser flat panel display technology. The performance of the backlight directly affects the color, brightness uniformity, power consumption and other performance indicators of the laser flat panel display device. The requirements for high brightness, good brightness uniformity and color rendering, thin shape, and low power consumption of the backlight are necessary. Professionals engag...
