[0008] Preferably, the special adhesive is OCA film.

[0009] Preferably, it is one of the following: adhesive structural adhesive, silicone, or double-sided adhesive.

[0010] Preferably, the cold-bent LCD screen can be a touch LCD screen or a non-touch ordinary LCD screen.

[0011] Preferably, the hot-bent glass cover can be coated or laminated.

[0012] In summary, this utility model provides a novel in-vehicle curved display module. This design uses a combination of a hot-bent glass cover and a cold-bent LCD screen to achieve a low-stress module state, reducing the reliance on high-precision fixtures in the production process.

[0013] This design allows for the selection of either a touch-screen LCD display (FOG) or a non-touch-screen LCD display to fulfill functional requirements, thus reducing the need for a separate touchscreen assembly process.

[0014] After the hot-bent glass cover plate and cold-bent LCD screen are bonded together, they are bonded to the curved backlight module with adhesive to achieve good optical effects and user experience. The integrated backlight module after die casting can achieve good structural strength, reduce the assembly process of an independent backlight source, and improve production efficiency.
