Backlight module based on coreless optical fiber

The invention discloses a backlight module based on a coreless optical fiber, relates to the technical field of display, and aims to solve the problems that an existing double-sided display is high in manufacturing cost, and the light and thin design of the module cannot be realized. The double-sided display module comprises a first diaphragm assembly, a second diaphragm assembly and a coreless optical fiber, wherein the coreless optical fiber is coiled between the first diaphragm assembly and the second diaphragm assembly. The coreless optical fiber is used for replacing a traditional light guide plate, the manufacturing cost is lower than that of a traditional double-face displayer of a back-to-back structure, the thickness of the coreless optical fiber ranges from 50 micrometers to 200 micrometers, the backlight module based on the coreless optical fiber can reach 0.5 mm in limit, and the weight and the thickness of the module are reduced. 本申请公开了基于无芯光纤的背光模组，涉及显示技术领域，以解决现有的双面显示器制造成本较高，无法实现模组轻薄化的设计。所述双面显示模组包
