Of course, the elastic screw connection structure may also be other structures having the same function, such as replacing the elastic arm with an elastic piece or other elastic components.
Specifically, the screw structure is a screw post 2012, the screw post 2012 is located at a side of the elastic arm 2011 close to the rear case 5, and functions as: the screw post that sets up like this can be closer to the backshell to make things convenient for elastic arm and backshell to carry out threaded connection. Of course, the thread structure can also be a screw hole or the like, and the thread structure can be selected according to the requirement.
Specifically, be equipped with first screw hole 2013 on screw post 2012, be equipped with second screw hole 501 on backshell 5, first screw hole 2013 carries out threaded connection through screw 6 with second screw hole 501, and the effect: the two screw holes are connected with the screws, so that the connection between the rear shell and the panel is more convenient. Of course, the screw post may also be other structures with the same function, such as an external thread on the screw post.
Specifically, the elastic screw structure 201 is located at one side of the panel 2 in the length direction, and functions as: because the duplex screen is 700mm long, the deformation of the panel is very large, so only one side of the panel in the length direction needs to absorb the dimensional deformation tolerance.
Specifically, referring to fig. 5 to 6, the number of the elastic screw structures 201 includes two, and the two elastic screw structures 201 are sequentially distributed along the width direction of the panel 2, and function as: this allows better absorption of stresses that occur after assembly.

Stress makes elasticity spiro union structure warp to reach unable or reduce and transmit stress to the liquid crystal display subassembly of laminating entirely, thereby make the screen not receive stress, also can not aggravate the Mura value of screen. And the screw can be fixed with panel, PCB board, five metals support and backshell spiro union together to guarantee the fastness of product.
Specifically, the panel 2 is a plastic panel, functioning: although the plastic deformation of the plastic panel is larger, the stress can be absorbed by the elastic screw connection structure. It should be noted that the panel may be a plastic panel, or may be other panels having the same function, and the elastic screw structure may be used to absorb the stress, so as to reduce the Mura condition.
Specifically, the rear case 5 is a plastic rear case, and may be other rear cases having the same function.
Specifically, the full-lamination lcd panel assembly 1 and the panel 2 are fixed by the double-sided tape 7.
Specifically, the fully-adhered liquid crystal display assembly comprises a touch cover plate, OCA glue, CF glass (namely CF glass) and TFT glass (namely TFT glass) which are sequentially distributed, and the TFT glass and the panel are fixed through double-sided adhesive tapes.
In summary, the present invention can produce the following beneficial effects: 1. the stress caused by assembly is reduced, and the Mura condition of the fully-attached liquid crystal display screen is reduced; 2. the display effect of the instrument and the display screen of the information entertainment system is improved.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
