摘要： A light guide plate (LGP) includes a positioning block that includes a positioning block body and a liquid filled and hermetically sealed in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.

摘要： A backplane structure includes a backplane and a curved supporting frame. The curved supporting frame includes a first and a second region, wherein, a curvature radius of the second region is less than a curvature radius of the first region. The curvature radiuses of the supporting frame are evenly changed from the first region toward the second region. The backplane is a flat-thin sheet, and the supporting frame is installed at a surface of the backplane and bends the backplane to form a curved surface having an even curvature radius. A curved display device includes a display panel and a backplane structure. Different positions of the supporting frame provide different curvature radiuses to apply different supporting forces near or away from the supporting frame such that all positions of the backplane can maintain a target curvature radius. Curvature radiuses of the backplane structure and the curved display device are equal.

摘要： The present invention provides a liquid crystal display device and a method for manufacturing a light guide plate (LGP) positioning block thereof. The LGP positioning block (9) of the liquid crystal display device includes a positioning block body (91) and liquid (93) hermetically sealed in the positioning block body (91). The positioning block body (91) possesses elasticity. In a low temperature, the liquid (93) is condensed and expanded so as to enlarge the size of the positioning block body (91) to compensate the reduction of the size of a light guide plate (3) due to contraction caused by cooling; and in a high temperature, the elasticity of the positioning block body (91) absorbs the expansion of the size of the light guide plate (3) caused by heating. The LGP positioning block (9) of the liquid crystal display device is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate (3) thereby providing high reliability of the liquid crystal display device and stable taste of displayed images.

摘要： 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.
