Problems solved by technology

Usually, the size of quantum dots is on the nanometer scale, and its surface defects will make it more sensitive to water and oxygen erosion. Generally, barrier packaging is required to isolate water and oxygen erosion. For example, quantum dots are directly packaged in LEDs. However, due to the high temperature in the LED, it is not conducive to the long-term stable use of quantum dots, and the small size of the LED makes it difficult to design water and oxygen barriers for quantum dots. Low

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a PCB, LED lamp beads and a quantum dot packaging structure. The LED lamp beads are arranged on the PCB,and light-emitting chips are packaged in the LED lamp beads. The quantum dot packaging structure is arranged on the side, away from the PCB, of the LED lamp bead, and the quantum dot packaging structure comprises a quantum dot material layer and a packaging body wrapping the quantum dot material layer. According to the backlight module, the quantum dot material is packaged in the packaging body to form the quantum dot packaging structure, and then the quantum dot packaging structure is arranged on the side, away from the PCB, of the LED lamp bead, so that the temperature of the environment where quantum dots are located is low, reliability is good, manufacturing difficulty is relatively low, and quantitative production of the backlight module is facilitated.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight module and a display device. Background technique [0002] Display devices, such as LCD TVs, because the LCD panel in the LCD TV cannot achieve self-illumination, it needs to provide light source through the backlight, and finally realize the full-color pixel display through the switch of the red, green and blue sub-pixels of the LCD panel, so the spectrum of the backlight It determines the optical display effect of the final TV (television). High color gamut display is one of the main development directions of TV at present, and the realization of high color gamut is mainly achieved by narrowing the half-wave width of the blue, green and red spectrum. [0003] Traditional TV backlights use LED (light-emitting diode) blue light chips to excite phosphors to form a white light spectrum, and phosphors have a wide excitation spectrum, generally above 50nm, result...
