The invention discloses a liquid crystal display (LCD) based on an insulation backplane. The LCD comprises a backplane, a display driving circuit board, and a metal front frame, wherein the backplane comprises a sidewall at the side surface of the LCD and a base plate at the bottom surface of the LCD; the metal front frame is fixedly connected with the sidewall of the backplane; and the display driving circuit board is fixed on the base plate. The LCD also comprises a metal insert, and the display driving circuit board is electrically connected with the metal front frame through the metal insert. In the invention, the display driving circuit board is connected with the metal front frame through the metal insert, compared with a conductive aluminum foil, the metal insert has higher strength and reliability, and the problems of falling, damage, tearing, etc. are not easy to occur. In addition, the metal insert can be assembled and disassembled as a whole conveniently, and thus, no additional trouble can be caused in the rework process.

Abstract:
The invention provides an LCD module and a frame thereof. The frame comprises a plurality of segmented pieces constituting the frame; the frame comprises a front frame, and a middle frame; the structure of the segmented piece(s) constituting the front frame is the same as that of the segmented piece(s) constituting the middle frame. Because the front frame and the middle frame of the LCD module of the invention are comprised of a plurality of segmented pieces of the same structure, the segmented pieces constituting the front frame can be superposed outside the segmented pieces constituting the middle frame, and then the front frame and middle frame of different sizes can be respectively formed. Thus, because the segmented pieces constituting the front frame and middle frame are of the same structure, the segmented pieces can be produced by only one mold, and the front frame and the middle frame can be produced just by the same mold, thereby saving the production cost. In addition, the segmented pieces can be cut only on one section without singly producing each segmented piece, thereby further reducing the production cost of LCD modules.
Abstract:
The present invention provides an optical fiber for backlight module, the optical fiber being a spiral, including: light-incident part to guide in light, near light-incident part close to light-incident part, and faraway light-incident part away from light-incident part; pitch and/or spiral radius of spiral optical fiber gradually decreasing from near light-incident part towards faraway light-incident part. The present invention also provides backlight module and LCD. With spiral optical fiber to guide in light from light source (e.g., LED or CCFL), backlight module and LCD use optical fiber as backlight source of backlight module to separate light and heat inside backlight module to avoid heat-dissipation problem. As such, the present invention effectively improves life span, optical characteristics and reliability of backlight module. Because light source is not inside backlight module, the known heat-dissipation means can be applied to increase life span of light source.

The present invention provides a liquid crystal glass panel packaging structure, which includes a package box and a plurality of cushioning bodies arranged inside the package box. The package box includes a lower case and an upper case mating the lower case. The cushioning bodies are airbag cushioning bodies arranged inside the lower case at locations corresponding to corners of a liquid crystal glass panel. The liquid crystal glass panel packaging structure uses airbag cushioning bodies to serve as cushioning devices for a liquid crystal glass panel, whereby with the airbag cushioning bodies being arranged at locations corresponding to corners of the liquid crystal glass panel, better protection is provided to the liquid crystal glass panel to prevent the product from being damaged by external forces. Further, the cushioning bodies of the present invention have a simple structure, is easy to manufacture, and can effectively lower down the manufacturing cost.
Abstract:
A backlight module includes a light guide panel (LGP), and a backplane. The LGP is arranged in the backplane, each side wall of the backplane is configured with a through hole(s), and the fixing pieces penetrate through the through holes and then fix the LGP. The fixing pieces are arranged on the side surface of the backplane of the present disclosure, and the fixing pieces are used for preventing the LGP from upward and downward moving in the vertical direction.
Abstract:
The invention provides an optical assembly positioning structure, an LCD device, and a manufacturing method thereof. The optical assembly positioning structure includes a positioning part and a clamping part used for clamping different optical layers of the optical assembly; a connecting part is arranged between the positioning part and the clamping part, and the positioning part is connected and fixed to one end of the clamping part by the connecting part. The optical layers of the optical assembly of the invention are fixed by separate positioning structures. The positioning part and clamping part of the positioning structure are respectively in contact with the upper and lower surfaces of the optical assembly. The positioning part is fixed and connected to the clamping part by the connecting part. Thus, all optical layers of the optical assembly are clamped and fixed. The optical assembly is assembled firstly, and then the assembled optical assembly is totally fixed in the backlight module, thereby reducing human power; in addition, all the optical layers are integratedly assembled, thereby effectively reducing the relative displacement between the optical layers, and ensuring that large scratch will not be generated between the optical layers.
Abstract:
The present invention provides a backlight module, which includes a backplane, a backlight source arranged inside the backplane, a light guide plate arranged inside the backplane, an optic film assembly arranged on the light guide plate, and a split mold frame arranged inside the backplane. The split mold frame includes a plurality of spaced corner pieces respectively set on the optic film assembly. The corner pieces have a support surface that is distant from the optic film assembly for supporting thereon a liquid crystal display panel. The backlight module of the present invention uses an upper surface of a split mold frame to serve as a support surface for a liquid crystal display panel thereby enlarging the supporting area for the liquid crystal display pane, improving supporting stability and also effectively preventing the occurrence of light leakage, ensuring luminance of the backlight module, and enhancing optic grade.
Abstract:
The present invention discloses a direct type backlight module and a Liquid Crystal Display (LCD) device. A direct type backlight module comprises a diffuser plate located on the light emergent surface and a backplane opposite to the diffuser plate; a support pin is arranged between the backplane and the diffuser plate, and the support pin is rigidly fixed to the backplane. Because the support pin of the present invention is rigidly fixed on the backplane, there is no direct relationship between the present invention and the thicknesses of the backplane and the LED light plate fixed on the backplane, and no noise is produced by the loosed “mushroom head” due to infirm gripping; therefore, the support pin can be firmly fixed. The support pin can be rigidly fixed by modes facilitating the automatic operation like SMT welding and riveting, which is advantageous for promoting the productivity and the conformance rate.
