In a specific embodiment, the fixing portion 502 adsorbs a part of the surface of the back surface 401 of the circuit board 4, so that the rest of the surface of the back surface 401 of the circuit board 4 is exposed.
In another embodiment, the first suction cup 501 and the fixing portion 502 are electrically conductive and electrically connected, and the fixing portion 502 is electrically connected to the GND layer (not shown) on the back side of the circuit board 4 by means of conductive adhesive or soldering, so that the GND layer on the back side of the circuit board 4 is electrically connected to the backplate 201, which reduces the presence of conductive cloth in the prior art, further simplifies the structure of the display device 100, and has conductive performance.
Specifically, the surfaces of the first suction cup 501 and the fixing portion 502 have conductive coatings, so that the first suction cup 501 and the fixing portion 502 have conductivity, or the materials of the first suction cup 501 and the fixing portion 502 are conductive materials, that is, the first suction cup 501 and the fixing portion 502 are made of conductive materials, so that the first suction cup 501 and the fixing portion 502 have conductivity. The fixing portion 502 has a conductive layer on a surface or a conductive wire inside.
In this embodiment, the height of the first suction cup 501 and the number and positions of the fixing mechanisms 5 may also be adjusted, and the specific adjustment manner and function may refer to the adjustment manner and function of the height of the first suction cup 501 and the number and positions of the fixing mechanisms 5 provided in the first embodiment and the second embodiment, which are not described herein.
The application provides a display device 100, which comprises a display panel 1, a backboard 201, a fixing mechanism 5, a flip chip film 3 and a circuit board 4. By adopting the fixing mechanism 5 having the suction cup and the fixing portion 502, the suction cup only sucks the back surface 401 of the circuit board 4, or the fixing portion 502 is only fixed on the back surface 401 of the circuit board 4, the problem that the fixing mechanism 5 and other various electronic component layouts on the front surface of the circuit board 4 interfere with each other can be solved. A part of the surface of the back surface 401 of the circuit board 4 is sucked by the first suction cup 501; or the fixing portion 502 adsorbs a part of the surface of the back surface 401 of the circuit board 4 so that the remaining part of the surface of the back surface 401 of the circuit board 4 is exposed; compared with the prior art, after the circuit board 4 and the backboard 201 are incompletely contacted and attached, the front surface and the back surface of the circuit board 4 can be used as heat dissipation surfaces for dissipating heat, so that the heat dissipation effect of the circuit board 4 is better. Meanwhile, the fixing mechanism 5 of the display device 100 can select the positioning range and the number of the fixing mechanisms 5, so that the stability and the flexibility of fixing the circuit board 4 are improved. By making the first suction pad 501 and the second suction pad 503 conductive, the first suction pad 501 is in suction contact with a GND layer (not shown) of the back surface 401 of the circuit board 4; or the first suction cup 501 and the fixing portion 502 have conductivity and are electrically connected, and the first suction cup 501 is in suction contact with the GND layer of the back surface 401 of the circuit board 4; or the first suction cup 501 and the fixing portion 502 are electrically conductive and electrically connected; the GND layer of the back surface 401 of the circuit board 4 is electrically connected to the backplate 201, reducing the presence of conductive cloth in the prior art, and further simplifying the structure of the display device 100. The height of the fixing mechanism 5 can be adjusted, and the circuit board 4 is parallel to the surface of the backplate 201 for fixing the fixing mechanism 5, so that the fixing mechanism 5 in the application can reduce the bending degree of the flip chip film 3, that is, the fixing mechanism 5 in the display device 100 provided by the application can solve abnormal display caused by bending. The shape and structure of the fixing mechanism 5 of the display device 100 provided by the application bring a plurality of beneficial effects to the display device 100.
