The connection member facilitates the connection of the first backlight unit 300 and the second backlight unit 400 by using the adsorptivity of the magnet, facilitates the detachment of the second backlight unit 400, and facilitates the replacement of the second backlight unit 400. The convenient attraction connection can be realized no matter the magnetic poles attract out of phase or the magnet attracts iron materials.
In this embodiment, the first backlight unit 300 includes a second back plate close to one side of the second backlight unit 400, and the second back plate is a glass back plate and is flat and smooth. The first connection unit 430 includes a plurality of first suction cup members positioned at a side of the first backlight unit 300 adjacent to the second back plate. The second backlight unit 400 is firmly fixed to the first backlight unit 300 by using atmospheric pressure through the air discharge by the pressing of the first chuck member and the second back plate, thereby achieving the effect of connecting the first backlight unit 300 and the second backlight unit 400. Meanwhile, the first suction pad part facilitates the detachment of the second backlight unit 400, and the replacement of the second backlight unit 400 can be facilitated.
In this embodiment, the first connection unit 430 includes a second adhesive layer disposed on the second backlight unit 400 and a side close to the first backlight unit 300, and the second adhesive layer is used for adhering the first backlight unit 300 and the second backlight unit 400. The first backlight unit 300 and the second backlight unit 400 are fixed by bonding through a second bonding layer, so that the cost is low, the requirement on the technical level is not high, and the production is convenient.
In this embodiment, the image sensor 600 further includes a sixth reflective layer located on a side close to the light guiding ring 440. The sixth reflective layer may reflect light leaking toward the image sensor 600, thereby preventing abnormal operation of the image sensor 600 due to temperature or light.
