Example 1

As shown in FIG. 7, this embodiment provides an automobile instrument central control combination device, which includes a cover plate 1, a display part 2, a frame body 3, a circuit board 4, and a back shell 6 arranged on the rear side of the cover plate 1. The display component 2 is fixedly mounted on the front of the frame 3, the circuit board 4 is mounted on the back of the frame 3, and the display component 2 includes at least one display screen and a display corresponding to the display screen. Backlight source, it should be noted that, here can be that each display screen corresponds to a matching backlight source, that is, multiple display screens do not interfere with each other, and multiple backlight sources do not interfere with each other. When a set of display screens and backlight sources are damaged, it does not affect the use of the rest; it can also be that multiple displays correspond to a matching backlight source, that is, multiple displays can share the same backlight source, which can reduce the number of backlight sources. The number of products can improve assembly efficiency.
