20120262644 | Liquid Crystal Display and Backlight Module Thereof - A liquid crystal display (LCD) and a backlight module thereof is disclosed. The backlight module comprises a backplate and a light guide plate. The backplate comprises a bottom wall and a sidewall disposed at a periphery of the bottom wall and extending perpendicular to the bottom wall. The light guide plate is supported on the bottom wall. At least one positioning bent-piece is disposed to be bent from the bottom wall, and the positioning bent-piece abuts against a side edge of the light guiding plate to position the light guide plate. In this way, by using the positioning bent-piece disposed on the bottom wall of the backplate to position the light guide plate, the need of disposing an additional positioning structure on the light guide plate is eliminated, so the product yield of light guide plates can be improved. | 10-18-2012 |
20120300492 | Display Device and Backlight Module Thereof - A backlight module and a display device comprising the same are disclosed. The backlight module comprises a light source and a backplate. The backplate comprises an aluminum extruded piece and a plastic baseplate. The plastic baseplate is fixedly connected to a side of the aluminum extruded piece, and the light source is disposed on a sidewall of the aluminum extruded piece that is located at a side away from the plastic baseplate. The backlight module and the display device of the present disclosure have the aluminum extruded piece formed as a part of the backplate of the backlight module and have the light source integrated onto the aluminum extruded piece directly. In this way, heat generated by the light source can be transmitted through the aluminum extruded piece to the atmosphere directly to reduce contact heat resistance, thus improving the heat dissipation efficiency. | 11-29-2012 |
20140111067 | Front Case and LCD Device Using the Same - The present invention discloses a front case for assembling with a display module of an LCD device, and the front case is a hollow shell body formed by four side plates, the front case comprising: an inner baffle plate and an outer baffle plate mutually parallel and perpendicularly extended from both sides of each of the side plates, and the inner baffle plate and the outer baffle plate are disposed at the same surface of the front case; multiple hooks disposed on one of the side plates for fixing to the display module; and multiple compensation plates disposed at the inner baffle plate corresponding to the side plate having the hooks for compensating a curve bending caused by assembly of the hooks and the display module so that a contact surface between the front case and a display panel of the display module is flat. The present invention also provides an LCD device using the above front case. According to the present invention, it can maintain the flatness of the edge of the front case, reducing appearance deformation of the front case of the television after assembly, and reducing the gap between the front case and the display panel of the display module. | 04-24-2014 |
20140118660 | Liquid Crystal Display Device - The present invention provides a liquid crystal display device, which includes a backlight module, a backlight module, a mold frame arranged on the backlight module, a liquid crystal display panel arranged on the mold frame, and a front enclosure arranged on the liquid crystal display panel. The backlight module includes a backplane, a backlight source mounted in the backplane, and a light guide plate received in the backplane. The backplane is made of a conductive material and has a bottom board and side boards connected to the bottom board. At least one of the side boards forms protrusions projecting outward from an outside surface thereof. The front enclosure has an inside surface opposing said one of the side boards and including a conductive film mounted thereto and having an end in contact engagement with the liquid crystal display panel and an opposite end in contact engagement with the protrusions. | 05-01-2014 |
20140119055 | Light Coupling Arrangement of Backlight Module - The present invention relates to a light coupling arrangement of a backlight module, which includes a heat dissipation board, an LED light bar, a light guide plate, and a backplane. The heat dissipation board is positioned at a light incidence side of the light guide plate and fixed to the backplane. The LED light bar is fixed to the heat dissipation board and opposes the light incidence side of the light guide plate. The heat dissipation board forms a bump that faces the light incidence side of the light guide plate. The bump has a top that is in contact with the light incidence side of the light guide plate to constrain movement of the light guide plate in a light incidence direction. The light guide plate has a light-opposite side, and an elastic structure is received between the light-opposite side and a side wall of the backplane. | 05-01-2014 |
20140132878 | Liquid Crystal Display Device - The present invention provides a liquid crystal display device, which includes a backlight module, a mold frame arranged on the backlight module, a liquid crystal display panel arranged on the mold frame, a front enclosure made of a plastic material and arranged on the liquid crystal display panel, and a conductor piece mounted on the front enclosure. The backlight module includes a backplane made of a conductive materiel, a backlight source mounted in the backplane, and an optic film assembly received in the backplane. The conductor piece includes a first conductive section to which a second conductive section is connected. The first conductive section is arranged between the front enclosure and the liquid crystal display panel to engage the liquid crystal display panel. A bolt is received through the second conductive section of the conductor piece, the front enclosure, and the mold frame to engage and fix to the backplane. | 05-15-2014 |
20140333867 | LIQUID CRYSTAL DISPLAY AND MOLD FRAME THEREOF - The invention provides a liquid crystal display (LCD), which includes: mold frame, back plate, optical plate, at least an optical film and LCD panel; wherein optical plate disposed on top of back plate; optical film disposed on top of optical plate; mold frame pressing optical film to fix optical plate and optical film; mold frame including at least a frame border and a plurality of vacuum tubes, wherein vacuum tubes having first port disposed at frame border; LCD panel disposed at frame border and covering first port; air inside vacuum tubes being sucked out through second port of vacuum tubes to fix LCD panel by adsorption. LCD uses the vacuum tubes disposed on mold frame to fix LCD panel by adsorption to realize borderless design. The adsorption operation is simply and can lessen possibility of breakage when LCD panel expands or shrinks to improve yield rate and competitiveness. | 11-13-2014 |
