Abstract

The invention discloses a backlight module and a display device. The backlight module comprises an LED light source and a fluorescent glue layer, wherein the LED light source comprises a substrate andmini LED lamp beads arranged on the substrate in an array; the fluorescent glue layer is arranged in the light emitting direction of the LED light source, and the portions, away from the LED light source, of the fluorescent glue layer are provided with rectangular pyramid structures; the mini LED lamp beads correspond to the rectangular pyramid structures one to one. The technical problem that anexisting mini LED backlight module is thick is solved.

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] Mini LED technology can realize direct backlight Local Dimming (local dimming) design, achieve high dynamic range screen effect, and make the picture more delicate. In addition, while reducing the power consumption of the backlight, the brightness of the backlight module is improved by providing a high-brightness surface light source. [0003] Specifically, the mini LED lamp beads are stamped on the substrate where the wiring is completed, and then the phosphor or phosphor film is fixed by spraying or film pressing. Wherein, the substrate may be an FPC board (Flexible Printed Circuit Board, flexible printed circuit board) or a BT (Bismaleimide Triazine, BT resin substrate material) board. Control the mini LED lamp beads through the circuit on the substrate to achieve surface light source and Local Dimming e...
