To facilitate a further understanding of the present disclosure, a process for manufacturing the functional layer 2 is provided herein by way of example. Firstly, printing a functional mark 24 on a transparent plate through ink, for example, shielding a functional mark 24 area by using a shielding object, taking away the shielding object after printing the ink, and obtaining the left hollowed-out area as the functional mark 24; for example, the ink may be printed integrally, the functional mark 24 may be hollowed out by laser engraving, and the circuit 22 may be printed by conductive silver paste, and the functional buttons may be attached. This completes the dual printing of the pattern and function.

In other embodiments, the vehicle interior trim part may further include a light emitting element 5, and the light emitting element 5 is integrally provided on a surface of the plate body 21 on a side facing the support layer 1. The light emitted by the light-emitting element 5 can be emitted from inside to outside, and the light transmitted through the functional mark 24 is projected on the translucent leather to form the pattern of the functional mark 24. In order to reduce the overall thickness of the vehicle-mounted interior trim part, the light-emitting element 5 can select a patch type LED lamp strip, the patch type LED lamp strip has long service life, higher brightness, is more energy-saving and environment-friendly, has smaller heat release in the use process, and can not cause the local temperature to be too high so as to interfere with the realization of the functions of the functional layer 2.

The function buttons 23 in the functional layer 2 may be capacitive touch switches or resistive touch switches. The function button 23 is turned on or off by a fluctuation of capacitance or resistance generated by a portion of the human body, such as a finger, approaching the touch switch.
