Abstract

The invention discloses a direct type backlight module. The direct type backlight module comprises a diffusion plate, a reflection plate and a plurality of light sources. The reflection plate is arranged below the diffusion plate and spaced from the diffusion plate, the reflection plate is provided with a protruding column, and the protruding column is arranged adjacent to the diffusion plate andprovided with an installation part. A light source penetrates through a mounting part; and the protruding column is used for simultaneously supporting the diffusion plate and the light source.

Description

technical field [0001] The present invention relates to a direct-type backlight module and a display device, in particular to a direct-type backlight module and a display device that can prevent the diffusion plate and the light source from being deformed due to thermal expansion and contraction of the support without affecting optical characteristics . Background technique [0002] With the rapid progress of liquid crystal display (liquid crystal display, LCD) production technology, and its advantages of lightness, lightness, power saving and no radiation, the liquid crystal display is widely used in personal digital assistants (personal digital assistants, PDAs). , Notebook computers, digital cameras, digital camcorders, mobile phones, computer screens and LCD TVs and other electronic products. However, since the liquid crystal display panel in the liquid crystal display is a non-self-illuminating display panel, it needs the light source provided by the backlight module t...
