Abstract

The invention discloses a display device which comprises a backlight module and a display panel. The backlight module comprises a circuit board, a light-emitting device and a quantum dot film layer. According to the embodiment of the invention, a fluorescent layer is arranged in an orthographic projection area of the light-emitting device on the circuit board, and the fluorescent layer can absorb the incident light and excite the white light so that when the light emitted by the light-emitting device enters the orthographic projection area, the fluorescent layer can excite the white light by using a part of the light, the intensity of the light reflected to the quantum dot film layer is relatively weakened, and the requirement of the quantum dot material on the saturation of the exciting light can be just met; and the exciting light of the quantum dot material and the unexcited blue light can be mixed into white light, and the white light and the white light excited by the fluorescent layer together provide white backlight for the display panel. Therefore, the problem of bluing right above the light-emitting device is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] As the current mainstream display screen, liquid crystal display has the advantages of low power consumption, small size, and low radiation. The liquid crystal display panel is a non-self-illuminating panel and needs to be used in conjunction with a backlight module. [0003] Light Emitting Diode (LED for short) is used as a backlight source, which has the advantages of high backlight brightness and no decrease in brightness after long-term use, and the body of the LED backlight is thinner, which can realize thinner and lighter products. [0004] With the launch of the low-cost quantum dot QD solution, the current backlight module can use blue LEDs with quantum dot film solutions to achieve high-color gamut and high-quality display effects. In order to reduce the production cost, the arrangement quantity of LEDs can be re...
