Flat panel display device, stereoscopic display device, and liquid crystal display device

摘要

The present invention provides a flat panel display device, a stereoscopic display device, and a liquid crystal display device. The flat panel display device includes a backlight system and a display panel, wherein the backlight system includes a light source, a light homogenization mechanism, and a back frame; the back frame carries the light source and the light homogenization mechanism and the back frame includes at least two assembling pieces. The at least two assembling pieces are joined to form the back frame. The back frame further includes a bracing piece that is set in pawl mating engagement with the assembling pieces. The present invention forms a back frame through joining assembling pieces so that the structure of a mold for back frame is simple, the expenditure for the back frame mold is reduced, the material for the back frame is saved, and the cost is lowered down. Further, through the pawl mating arrangement of the bracing piece and the assembling piece, the bracing piece of the back frame realizes fast mounting and removal.

主权项

1. A flat panel display device, wherein the flat panel display device comprises a backlight system and a display panel, wherein: the backlight system comprises a light source, a light homogenization mechanism, and a back frame; the back frame carries the light source and the light homogenization mechanism and the back frame comprises at least two assembling pieces, the at least two assembling pieces being joined to form the back frame, the back frame further comprising a bracing piece, the bracing piece being set in pawl mating engagement with the assembling pieces; and
wherein the back frame comprises at least two primary assembling pieces, the at least two primary assembling pieces being joined to form a main frame structure of the back frame, the at least two primary assembling pieces comprising a first primary assembling piece and a second primary assembling piece, the first primary assembling piece having an end forming at least two joint sections, each of the joint sections having a structure mating an end of the second primary assembling piece, the first primary assembling piece selectively using one of the joint sections to join the corresponding end of the second primary assembling piece such that the corresponding end of the second primary assembling piece is selectively jointed to one of the at least two joint sections of the first primary assembling piece, and other joint sections of the first primary assembling piece are idle and without joining with any piece, a size of the back frame is determined by the first primary assembling piece and the second primary assembling piece, and the second primary assembling piece is a piece closest to the end of the first primary assembling piece and connected to the first primary assembling piece in a position-adjustable manner such that the size of the back frame is adjustable.
