[0028] The liquid crystal module of the present invention sets a local area of the flexible circuit board 400 between the backlight module 200 and the rigid circuit board 300 to form the hidden section 431, and sets the device area 432 on the side surface of the hidden section 431 facing the rigid circuit board 300, so as to weld the electronic components such as the peripheral circuit of the driving chip 600 and the boost circuit and protection circuit of the liquid crystal module on the device area 432 of the hidden section 431, and then opens the accommodating groove 310 on the side surface of the rigid circuit board 300 facing the flexible circuit board 400 to accommodate the electronic components 500, so that the electronic components 500 can be covered and protected by the rigid circuit board 300 without being exposed, and will not interfere with the internal structure of the terminal when the terminal is assembled, and there is no need to perform air avoidance design on the internal structure of the terminal, thereby improving the convenience of terminal design.
[0029] In this embodiment, the rigid circuit board 300 is bonded and fixed to the back side of the backlight module 200. Preferably, the rigid circuit board 300 can be bonded and fixed to the back side of the backlight module 200 by, but not limited to, a double-sided adhesive 700. When bonding the backlight module 200 and the rigid circuit board 300, the double-sided adhesive 700 needs to avoid the hidden section 431 of the flexible circuit board 400, that is, the double-sided adhesive 700 is roughly U-shaped, and the flexible circuit board 400 sandwiched between the backlight module 200 and the rigid circuit board 300 is located in the middle opening of the U-shaped double-sided adhesive 700.

[0031] Preferably, the spacing between each side of the accommodating groove 310 and the corresponding side of the device area 432 is not less than 1 mm, so as to reserve a sufficiently large avoidance space in the accommodating groove 310 to prevent the hard circuit board 300 from colliding with the electronic devices on the device area 432 when the accommodating groove 310 of the hard circuit board 300 is covered on the device area 432 of the flexible circuit board 400.
[0032] In this embodiment, one end of the flexible circuit board 400 is connected to the surface of the rigid circuit board 300 facing the backlight module 200. Of course, in a specific implementation, one end of the flexible circuit board 400 may also extend from between the backlight module 200 and the rigid circuit board 300 and be connected to the surface of the rigid circuit board 300 facing away from the backlight module 200 after being bent.
[0033] The flexible circuit board 400 includes a first connection end 410, a second connection end 420 and a routing section 430, the first connection end 410 is connected to the liquid crystal panel 100, the second connection end 420 is connected to the hard circuit board 300, and the routing section 430 is connected between the first connection end 410 and the second connection end 420; the hidden section 431 is located on one end of the routing section 430 close to the second connection end 420.
[0034] The routing section 430 has a bending section at one end close to the first connection end 410 . The first connection end 410 of the flexible circuit board 400 is bent by the bending section and connected to a surface of the liquid crystal panel 100 facing away from the backlight module 200 .
[0035] The liquid crystal module further includes a bonding circuit board 800 , one end of which is connected to a surface of the rigid circuit board 300 facing away from the backlight module 200 .
[0036] The other end of the bonding circuit board 800 is connected to the main board of the terminal when the terminal is assembled, so as to transmit signals between the main board and the liquid crystal module.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them.
