The embodiment of the invention also provides a display device 01, wherein the display device 01 comprises the liquid crystal display module 00 and the backlight module 3, when the first display panel 1 comprises the touch electrode TP, the touch electrode TP can be internally arranged in the first display panel 1 or arranged on the light emergent side of the first display panel 1, and at the moment, the first display panel 1 is positioned on one side of the second display panel 2, which is far away from the backlight module 3, so that the influence of the second display panel 2 on the touch electrode TP is avoided, and the touch sensitivity is ensured; or, when the second display panel 2 includes the touch electrode TP, in order to ensure the touch sensitivity, the second display panel 2 needs to be located on one side of the first display panel 1 away from the backlight module 2, and the resolution of the second display panel 2 needs to be consistent with the resolution of the first display panel 1, so as to ensure the normal display of the display device 01. The liquid crystal display module 00 can be applied to a vehicle-mounted display terminal product, the display device includes the display panel, and the beneficial effects generated by the display device are also the beneficial effects described in the above embodiments, which are not described again here.

The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
