Abstract

The embodiment of the invention provides a diffusion plate, a backlight module and a display device. The diffusion plate provided by the embodiment of the invention comprises a light-in layer, a quantum dot layer and a light-out layer, the light-out layer contains a blue-light-resistant material, the diffusion plate can be matched with a light source for use, the emergent light of the light source penetrates through the light-in layer and then enters the quantum dot layer, the quantum dots in the quantum dot layer are excited, the emergent light of the light source and the exciting light generated by the quantum dots are mixed to form mixed light, then the mixed light enters the light-out layer and is emitted out of thelight-out layer, and the blue light in the mixed light can be filtered by the blue-light-resistant material in the light-out layer so that the blue light emitted from the diffusion plate can be greatly reduced. The diffusion plate can be applied to the display device to achieve eye protection display.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a diffusion plate, a backlight module and a display device. Background technique [0002] The diffuser plate is widely used in liquid crystal display devices and other devices requiring backlight modules to provide uniform illumination. With the rapid development and wide application of liquid crystal display devices, the performance requirements for the diffusion plate in the backlight module are also increasing. [0003] Currently, the light sources used in liquid crystal display devices are usually LED lamps. However, the light emitted by LED lamps contains blue light, which has a short wavelength and high energy, which is harmful to human eyes and even causes eye diseases. The problem of eye injury has become the key to eye protection display. Contents of the invention [0004] Embodiments of the present application provide a diffusion plate, a backlight module...
