  • Patent number: 8558780
    Abstract: A display apparatus includes a backlight assembly, a first display panel assembly and a second display panel assembly. The backlight assembly includes a plurality of lamps disposed substantially parallel with each other. The backlight assembly emits first light through a first face and second light through a second face. The first display panel assembly is disposed adjacent to the first face to receive the first light. The second display panel assembly is disposed adjacent to the second face to receive the second light. The backlight assembly may further include a driving inverter electrically connected to first and second ends of the lamps to provide the lamps with driving voltages. Therefore, the backlight assembly applies light to the first and second display panel assemblies to reduce the number of backlight assemblies. Therefore, costs for manufacturing a display apparatus may be reduced.
