Abstract: A backplate molding device includes a top mold and a down mode. The top mold includes a plurality of punching heads having curved operation surfaces and a pressure plate. The punching heads are arranged in multi-sections and the pressure plate is arranged at a lateral side of the punching heads in the multi-section. An operation surface of the down mold is a curved surface engageable with the operation surfaces of the punching heads in the multi-section, and edges of the down mold cooperatively engages with the pressure plate to fix backplate materials. A punching process is applied toward the backplate material by bonding the operation surface of the punching heads with the operation surface of the down mold in sequence to plastically deform the backplate materials. The present disclosure also relates to a backplate molding method.

Abstract: The present disclosure proposes a backlight module having a middle frame, a back plate, an optical film arranged in the middle frame, a light guide plate arranged in the middle frame, and a reflective film arranged in the middle frame. A cavity is arranged in the middle frame. A liquid crystal panel is arranged on the middle frame. A plurality of first air-intake holes are evenly arranged and distributed on the surface of one side of the middle frame that is opposite to the liquid crystal panel. The first air-intake hole connected to the cavity. Compared with the related art, a liquid crystal display module fixed by means of vacuum adsorption is easy to be dismantled once the product with the liquid crystal display module is glitched or requires maintenance. The production cost is reduced since the liquid crystal display panel is not damaged when being dismantled.

Abstract: A snap-fit for fixing optical films is disclosed. The optical film includes at least one ear hook arranged above a border of a plastic frame. The plastic frame is assembled with a back frame so as to fix a light guiding plate within the back frame. The snap-fit includes a press portion and a connection portion extending from a first side of the press portion. The connection portion and the press portion cooperatively form an angle with a predetermined degree. The press portion presses the ear hook of the optical films on the border of the plastic frame. The connection portion clasps with the hook of the sidewall. By adopting the snap-fit, not only the narrow bezel design can be achieved, but also the optical film can be stably fixed. A backlight module with the above snap-fit and the liquid crystal display are also disclosed.
