  • Patent number: 10216038
    Abstract: The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.
