    摘要: The present disclosure provides a direct-type backlight module and a display apparatus. The direct-type backlight module may comprise: a backplane; a plurality of LED lamps distributed in an array which are positioned on the backplane; a diffusion plate above the plurality of LED lamps; and multiple optical fibers connecting two adjacent LED lamps of the plurality of LED lamps, each optical fiber being provided with a plurality of light transmission openings distributed at intervals towards the diffusion plate along its extension direction. Wherein part of light emitted from each LED lamp can be propagated along the optical fiber and transmitted to the diffusion plate via the light transmission openings. The direct-type backlight module directs part of the light emitted from the LED lamps through the plurality of light transmission openings to the diffusion plate using the optical fibers, which changes the LED lamps in the form of point light sources into area light sources. Therefore, the direct-type backlight modules provided in the present disclosure can obtain uniform illumination at the same time of reducing the number of LED lamps, without increasing the light mixing distance of the backlight modules, thereby improving light availability.
