Lamp bead module, backlight module and electronic equipment

Abstract

The invention provides a lamp bead module, a backlight module and electronic equipment, the lamp bead module comprises a support and a bowl cup arranged in the support, a wafer is arranged in the bowl cup, the bowl cup is filled with a first packaging adhesive, the first packaging adhesive covers the wafer, one side of the first packaging adhesive is provided with a second packaging adhesive, and the second packaging adhesive is in a convex lens shape. The second packaging adhesive is arranged on the light emitting side of the wafer, the second packaging adhesive is arranged on the side, away from the wafer, of the first packaging adhesive, a step groove is formed in the edge of the side, away from the wafer, of the bowl cup, and the second packaging adhesive covers the step groove. According to the lamp bead module, the bowl cup is filled with the first packaging adhesive, and the convex-lens-shaped second packaging adhesive is further arranged on the outer side of the first packaging adhesive; specifically, the second packaging adhesive is arranged to form the ball head to replace an optical lens in the prior art, the limitation of the thickness of the secondary optical lens is removed, so that the low light mixing distance is achieved; and the light and thin design of the product is facilitated.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a lamp bead module, a backlight module and electronic equipment. Background technique [0002] With the improvement of people's living standards, people gradually tend to pursue thinner and more beautiful designs when choosing electronic devices such as televisions. [0003] In the prior art, the LED lamp beads in the backlight module of the TV set need to be equipped with a lens to realize the refraction and diffusion of light, so that the point light source of the LED lamp beads forms a surface light source, which is irradiated on the diffusion plate and released on the screen. This optical lens design occupies the gap between the LED lamp bead and the diffusion plate in the backlight module, and cannot achieve a smaller light mixing distance, which is not conducive to the thin and light design of electronic equipment.

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a lamp bead module, a backlight module and electronic equipment, aiming to solve the problem that in the prior art, the design of the optical lens occupies the space between the LED lamp bead and the diffusion plate in the backlight module. The gap between them cannot achieve a smaller light mixing distance, which is not conducive to the technical problem of thin and light design of electronic equipment
