Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a glass cavity and blue light-emitting diodes. The glass cavity is internally provided with red light quantum dot material and green light quantum dot material in a packaging mode. The two ends of the glass cavity are each provided with one blue light-emitting diode. The red light quantum dot material and green light quantum dot material in the glass cavity correspondingly emit red light and green light after being excited by light emitted by the blue light-emitting diodes. In this way, the quantum dot material is arranged in the glass cavity in the packaging mode, the two ends of the glass cavity are each provided with one blue light-emitting diode, and the quantum dot material correspondingly emits red light and green light after being excited by the light emitted by the blue light-emitting diodes, so that the red light and the green light are mixed with blue light reflected by the surface of the glass cavity to form white background light, the function of a backlight source is achieved; besides, the two ends of the glass cavity are provided with the blue light-emitting diodes serving as excitation light sources, and narrow frame design of the display device is facilitated.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique

[0002] At present, by utilizing the luminescent properties of quantum dots, quantum dots can be used as molecular probes in fluorescent labels, and can also be used in display devices, using monochromatic quantum dots as the light source of backlight modules. After being excited by the light emitted by the color light-emitting diode, it emits monochromatic light mixed with blue light to form a white background light, which has a large color gamut and can improve the picture quality.

[0003] Quantum dots are the main technical development direction of high color gamut products. The main implementation methods of high color gamut backlights using quantum dots include quantum dot films, quantum dot tubes and quantum dot light-emitting diodes. Among them, the quantum dot film is the function of replacing the diffusion...
