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: The backlight module contains a back plate and a middle frame. The middle frame contains at least three positioning strips positioned along three edges on a side of the back plate facing a light emission face of the backlight module. A display device containing the backlight module is also disclosed. The back plate provides locking mechanisms involving side walls and locking pieces, and the separate strips of the middle frame are slid into position along the back plate and reliably locked. There is no need to use bolts or other fastening means, reducing the difficulty in assembly/disassembly. The thinning of the backlight module and the display device is effectively achieved.

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.

Abstract: The lighting device contains a substrate and a plurality of lighting elements arranged in at least two parallel rows on a front side of the substrate. The lighting elements of the two rows neighbor on each other. The front side of the substrate is configured so that an included angle is formed between the lighting elements of the two rows. Their light therefore converges within a Quantum Dots (QD) tube before entering a light guide plate. A backlight module incorporating the lighting device as such not only provides high saturation and high chromaticity, but also achieves greater optical coupling efficiency, thinner light guide plate and QD tube, reduced material cost and dimension.
Abstract translation: 照明装置包括基板和在基板的正面上以至少两个平行排布置的多个照明元件。 两行的照明元素彼此相邻。 基板的前侧被配置成在两行的照明元件之间形成夹角。 因此，它们的光因此在进入导光板之前收敛在量子点（QD）中。 结合照明装置的背光模块不仅具有高饱和度和高色度，而且还实现更大的光耦合效率，更薄的导光板和QD管，降低材料成本和尺寸。
