Abstract
The present invention relates to a positioning structure of a lamp tube, which is arranged on a display device. The lamp tube is arranged on a backboard and forms a bent part in a bent shape, a side board of the backboard corresponds to the bent part, simultaneously, a display screen is positioned on the backboard and covered on the lamp tube, and a display area of the display screen can cover the bent part. In addition, a fixed piece is arranged on the side board, the lower side of the fixed piece is upwards concavely provided with a lower groove and correspondingly sheathed on the bent part, elastic arms on both sides are respectively abutted on the bent part, and an open hole communicated with the bent part penetrates on the upper side so that the lamp tube can be fixed and positioned by the fixed piece and the elastic arms can hold the lamp tube and can not cause the lamp tube to be displaced and broken. Simultaneously, a light source can be emitted out through the open hole, the nonuniform brightness can not be generated, and the volume of the display device can not be enlarged by the bent part in the display area.
Description
Technical field
The present invention system refers to a kind of positioning structure of fluorescent tube that is applicable to light module of display device especially about a kind of positioning structure of fluorescent tube.
Background technology
Now light module of display device within it portion can be provided with a plurality of fluorescent tubes, by the light source of fluorescent tube, to illuminate the display screen of display device.Direct type backlight module with prior art is an example, the design of its fluorescent tube is slowly designed towards bend pipe (for example U-shaped pipe, C shape pipe etc.) mode by traditional straight tube, but bend pipe can have bigger brightness in the knee, display screen is uprised in this regional briliancy, so how to eliminate clear zone, and fixed lamp tube simultaneously simultaneously, the real considerable problem that become.
See also Fig. 1 for having fixedly synoptic diagram of first kind of fluorescent tube now, wherein show a fluorescent tube 91, this fluorescent tube 91 is located on the backboard 92, and this fluorescent tube 91 is described bending and is formed with a bend 911, remainder then forms straight sections 912, and the fixed form of this fluorescent tube 91 promptly is to be provided with rubber blanket 93 912 groups of straight sections, but mode like this can be blocked the light source of fluorescent tube 91, and make viewing area (as the right-hand part of Fig. 1 dotted line) produce the dark space, cause whole backlight module quality bad.
Seeing also Fig. 2 is fixedly synoptic diagram of second kind of fluorescent tube of prior art, for eliminating the problems referred to above, on fluorescent tube 94, can be formed with a bend 941 now equally, but this bend 941 is to be formed in the non-display area (as Fig. 2 dotted line left part), so design will cause the volume of whole backlight module to strengthen, and can't reach compact requirement.
Summary of the invention
Positioning structure of fluorescent tube of the present invention is arranged on the display device, and this display device includes a backboard, a fluorescent tube and a display screen, wherein, fluorescent tube is arranged on the backboard, and fluorescent tube is bending and is formed with a bend, and backboard upwards is bent with its bend corresponding to fluorescent tube of side plate, simultaneously, display screen is arranged on the backboard and covers fluorescent tube, and display screen and include a viewing area, and the crooked position of fluorescent tube is in the display screen viewing area.
In addition, positioning structure of fluorescent tube of the present invention includes a fixture, it is arranged on the side plate of above-mentioned backboard, and this fixture includes a upper side, a downside, a left surface and a right flank, wherein, left surface is connected upper side and downside respectively with right flank, and downside upwards is concaved with the bend that its correspondence of a low groove is socketed on fluorescent tube, left surface and right flank laterally convex with an elastic arm respectively it are resisted against the bend of fluorescent tube respectively, and upper side is through with a perforate, and it is communicated to the bend of fluorescent tube.
Therefore, fluorescent tube except that can by fixture fixing with the location, the elastic arm of fixture both sides also can withstand fluorescent tube and can not make it produce displacement and fracture.And the perforate that fixture is offered also can make the light source of fluorescent tube shed from perforate, and can not cause the situation of the bend generation light and shade inequality (dark space) of the fluorescent tube that is provided with fixture.Simultaneously, the bend of fluorescent tube still can be positioned at the display screen viewing area, thus can not strengthen the volume of display device, and can reach fluorescent tube location and the quality of keeping whole display device simultaneously.
Above-mentioned fixture can include a trailing flank, and trailing flank can upwards be provided with an assembled plate, and this assembled plate is positioned on the backboard side plate.And the quantity of above-mentioned fixing piece can be two, and assembled plate communicates with each other.Certainly, the quantity of fixture can be more than two, and the quantity of its visual fluorescent tube and increase or reduce.
In addition, above-mentioned fluorescent tube can include two electrode tips, and it is positioned at the opposite side of bend, and the downside of fixture can be adjacent on the backboard.Above-mentioned backboard can include a base plate and a reflector, and wherein reflector can overlappingly be arranged on the base plate, and fluorescent tube can be arranged on the reflector.
In addition, above-mentioned display device can be a LCD TV (LCD-TV).

Embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, cited below particularlyly go out preferred embodiment, and conjunction with figs., be described in detail below.
Seeing also Fig. 3 is three-dimensional exploded view of the present invention, and comprising a display device 1, in the present embodiment, this display device 1 is a LCD TV (LCD-TV), and it includes a backboard 11, a plurality of fluorescent tube 12 and a display screen 13.
Above-mentioned backboard 11 is formed by a base plate 101 and a reflector 102 combinations with one another, reflector 102 overlapping being arranged on the base plate 101 wherein, and a plurality of fluorescent tube 12 is arranged on the reflector 102.
Each fluorescent tube 12 is bending respectively, and be formed with a bend 121 respectively, and each fluorescent tube 12 includes two electrode tips 122, and this two electrode tip 122 is positioned at the opposite side of bend 121, by the power supply input of electrode tip 122, can make each fluorescent tube 12 effect and the generation light source.
