Abstract

The invention discloses a direct type backlight module. The direct type backlight module comprises a diffusion plate, a reflecting plate, a plurality of light sources, a plurality of supports and a plurality of buffer pads. The reflecting plate is arranged below the diffusion plate and spaced from the diffusion plate, the light sources are arranged between the diffusion plate and the reflecting plate, and the supports are arranged on the reflecting plate, located between the diffusion plate and the reflecting plate and used for supporting the diffusion plate and the light sources at the same time. Each support is provided with an installation portion, the light sources are directly arranged in the installation portions in a penetrating mode, a first gap is formed between each support and the diffusion plate, and a second gap is formed between each installation portion and the corresponding light source. The buffer pads respectively fill the first gaps and the second gaps.

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...
