    Abstract: 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.

    Abstract translation: 本公开提供了直接型背光模块和显示装置。 直接型背光模块可以包括:背板; 分布在阵列中的位于背板上的多个LED灯; 多个LED灯上方的漫射板; 以及多个光纤,其连接多个LED灯的两个相邻的LED灯,每个光纤设置有沿着其延伸方向以一定距离朝向扩散板分布的多个光传输开口。 其中从每个LED灯发射的光的一部分可以沿着光纤传播并且经由光传输开口传播到扩散板。 直接型背光模块将通过多个光传输开口的从LED灯发出的光的一部分引导到扩散板,该光纤将点光源形式的LED灯变成区域光源。 因此,在本公开中提供的直接型背光模块可以在减少LED灯的数量的同时获得均匀的照明,而不增加背光模块的光混合距离,从而提高光的可用性。
