Abstract

The invention provides a frame body for display equipment, a backlight module and a display device. The frame body comprises a frame main body and a first light conversion material dispersed in the frame main body. Due to adoption of the structure that the frame body comprises the frame main body and the first light conversion material dispersed in the frame main body, after the frame body is arranged on the outer side of a light-guiding plate to form the backlight module, light emerging from a light source runs through the light-guiding plate and emerges from at least one side surface of the light-guiding plate, and the emergent light of the light-guiding plate can change the wavelength by virtue of the light conversion material at the moment of coming into the frame body, so that the emergent light is changed into white light and light with other colors by changing the wavelength of the emergent light, thus leakage of blue light in the backlight module is effectively reduced, and the brightness uniformity and the chromaticity uniformity of the display equipment with the backlight module are improved.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular, to a frame used for a display device, a backlight module and a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements on the imaging quality of display devices. Currently commonly used display devices are limited by the spectral characteristics of white light LED light sources, resulting in a narrow color gamut and poor color reproduction capabilities. [0003] Because quantum dot materials have the advantages of continuous spectrum and adjustable light color, quantum dot materials are usually used in backlight modules in the prior art to increase the color gamut of display devices, thereby improving the image quality of display devices. [0004] In the actual application of the display device, when the quantum dot film is used as the light conversion film of the backlight module, a b...
