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.

Abstract: A gas intake device of magnetron sputtering vacuum chamber and a magnetron sputtering apparatus with the gas intake device, the gas intake device of magnetron sputtering vacuum chamber comprises a gas mixing box configured to receive and mix the gas, a gas intake box configured to introduce the gas into a vacuum chamber, and a connecting pipe configured to connect with the two boxes, the gas mixing box has one or more gas intake pipes. The gas intake device can increase the distribution uniformity after the gas enters inside the vacuum chamber, effectively decrease the impact force to the precision equipment(s) in the vacuum chamber, and extend the service life of the apparatus.

Abstract: The present invention discloses a light bar assembly and a backlight. The light bar assembly includes a light bar and a light bar fixing tape arranged on a back surface of the light bar, wherein the light bar fixing tape includes a main body part and multiple extension parts extending out from the main body part, the main body part is used for being attached to a flexible printed circuit board on the light bar, and the multiple extension parts are used for being attached to a backplane of a backlight to be assembled. The backlight includes a backplane and the light bar assembly, multiple through holes one-to-one corresponding to the positions of the multiple extension parts are formed on the backplane, and each extension part can penetrate through the corresponding through hole and be attached to the back surface of the backplane.

Abstract: The present disclosure provides a positioning frame for mounting a display module and a display panel. The positioning frame includes: a plurality of side plates enclosing an accommodation zone for receiving the display module; a support bed provided on at least a pair of side plates arranged opposite to each other, and connected perpendicularly with the side plates, for supporting the display panel of the display module; baffles corresponding to the support beds one by one, the baffles are provided at the display side of the display panel, perpendicularly connected with the side plate and arranged to be parallel with the support bed, for limiting the display panel in the normal direction; limiting holes provided in the baffle and support bed at least at one side; limiting element being plugged in the limiting hole for limiting the display in peripheral directions. The positioning frame enables effective assembling the display module.
