Abstract

The invention discloses a backlight module and a display device, the backlight module comprises a substrate, a plurality of LED chips and a sealing glue layer, the plurality of LED chips are arranged on the substrate at intervals, and the sealing glue layer is arranged on the substrate and covers the plurality of LED chips; one side, far away from the LED chips, of the sealing glue layer is provided with a plurality of concave parts, and the plurality of concave parts are arranged above the plurality of LED chips and are in one-to-one correspondence with the plurality of LED chips, so that light right above the LED chips is opened towards the periphery, side surface light emitting of the LED chips is increased, the brightness of an area between two adjacent LED chips is increased, and the probability of shadow generation is reduced.

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] Compared with traditional backlights, Mini light-emitting diode (Mini LED) backlights have the characteristics of ultra-thin, high brightness, and multi-segmentation. Therefore, the industry usually uses Mini LEDs as backlights for liquid crystal displays. [0003] The size and pitch of the Mini-LED, as well as the required optical distance (OD) are the key parameters determining the thickness and cost of the whole machine. When the product adopts a thin design, the OD requirements for the backlight also need to be It is getting higher and higher, that is, a smaller OD is required to meet the demand. However, limited by the light-emitting angle and light-emitting uniformity of the LED chip, the OD cannot be further reduced. When the OD is kept to a minimum, since the light emitted by the LED chip is concentr...
