The display component comprises a frame, a transparent support layer, a display screen, and a touchscreen. The transparent support layer, display screen, and touchscreen are all mounted on the frame. The touchscreen and display screen are respectively located on the front and back sides of the transparent support layer, and are respectively attached to the front and back sides of the transparent support layer. In this in-vehicle multimedia player, the touchscreen and display screen are respectively mounted on the front and back sides of the transparent support layer. While ensuring that the transparent support layer can stably support the touchscreen and display screen, the touchscreen can cover the transparent support layer, resulting in a better visual effect for the touchscreen compared to the transparent support layer, thereby improving the overall visual effect of the multimedia player.

[0004] While the existing in-car media players can meet basic usage needs, they only support MP3 music and cannot support various video and audio formats.
