Abstract
The utility model discloses an LED backlight LCD television, comprising a front shell and a rear shell adaptive to the front shell, wherein the front shell is embedded with a liquid-crystal glass board; the rear end surface of the front shell is level with the rear end surface of the liquid-crystal glass board; the inner side of the rear shell is provided with a ring-shaped step structure; the ring-shaped step structure is provided with a rear back board; the rear shell is further internally provided with a reflector plate, a light guide plate, and an optical film in sequence from back to front, wherein the front end surface of the optical film is level with the front end surface of the rear shell; and at least one side surface of the light guide plate is provided with a back light source. The LED backlight LCD television adopts LED as the back light source, thus being energy-saving and environment-friendly, and having attractive appearance; furthermore, an upper iron frame and a lower iron frame on a backlight screen are omitted, and the LED backlight LCD television is fixedly assembled by utilizing the characteristic that the front shell and the rear shell of the television are larger than all the components in the backlight screen, thus simplifying the internal structure of the television, saving materials and reducing cost.
Description
Technical field
The utility model relates to the LED-backlit liquid crystal TV set.
Background technology
Liquid crystal TV set comprises backlight screen, the control clamp, and the shell of power supply and television set is formed.As shown in Figure 1, backlight screen of the prior art then comprises liquid-crystalline glasses plate 1, blooming piece 2, and light guide plate 3, reflector plate 4, backlight 5, it all is fixed on one by last chase 6 and in the framework that chase 7 is formed down.Backlight screen is made into one and independently is connected with power supply with the control clamp behind the parts, and is installed in the shell of television set.But the last chase of backlight screen and the structure of following chase overlap with the shell existence of television set, cause structure to repeat, and production cost improves.
The utility model content
The technical problems to be solved in the utility model is to repeat in order to overcome the structure that liquid crystal TV set exists in the prior art, and the defective that production cost is higher relatively provides a kind of LED-backlit liquid crystal TV set simple in structure.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of LED-backlit liquid crystal TV set, it comprises a fore shell, one with the adaptive back cover of this fore shell, its characteristics are, are embedded a liquid-crystalline glasses plate on this fore shell, the rear end face of this fore shell is mutually concordant with the rear end face of this liquid-crystalline glasses plate; The inboard of this back cover is provided with an annular stepped structure, this annular stepped structure is provided with a postnotum, in this back cover by after an also ccontaining successively forward reflector plate, one light guide plate and a blooming piece, the front end face of this blooming piece is mutually concordant with the front end face of this back cover, is provided with backlight at least one side of this light guide plate.
Wherein, this backlight is a LED lamp bar.
Wherein, the cross section of this fore shell rear end face is greater than the cross section of this back cover front end face.
Wherein, be provided with a reflection shield behind this backlight.
Wherein, adopt the seal sealing between this liquid-crystalline glasses plate and this fore shell.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is: the utility model adopts LED as backlight, energy-conserving and environment-protective, good looking appearance.Further, the utility model omits the upper and lower chase on the backlight screen, utilizes the fore shell of television set and back cover to fix assembling greater than each parts in the backlight screen, has simplified the structure of inside, TV Festival, has saved material, has reduced cost.
Description of drawings
Fig. 1 is the structure cutaway view of backlight screen of the prior art.
Fig. 2 is the side schematic view of the LED-backlit liquid crystal TV set in the utility model.
Fig. 3 is the partial enlarged drawing after vertically the dissecing of the LED-backlit liquid crystal TV set among Fig. 2.
Embodiment
Enumerate preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
Shown in Fig. 2 and 3, the LED-backlit liquid crystal TV set in the utility model comprises a fore shell 9 and one and the adaptive back cover 10 of fore shell 9.In back cover 10, be provided with a ring ladder 11, be used for fixing a postnotum 1, this postnotum 1 can by be threaded, clamping or mode such as bonding be fixed on the ring ladder 11 of back cover 10.Be provided with a reflector plate 2 at postnotum 1 leading flank, leading flank at reflector plate 2 is provided with a light guide plate 5, one side of light guide plate 5 or a plurality of side are provided with LED lamp bar 3, and the light of the LED light-emitting component (not shown) on the LED lamp bar 3 is pointed to the center of light guide plate 5 by the side of light guide plate 5.Preferable, be provided with a reflection shield 4 at the opposite side of LED lamp bar 3 (promptly from light guide plate 5 side far away), thereby make light that LED lamp bar 3 sends can cover in light guide plate 5, reduce the loss of the energy.Leading flank in light guide plate 5 is provided with one deck blooming piece 6, and the leading flank of blooming piece 6 is mutually concordant with the front end face of back cover 10.The monolateral cross section of fore shell 9 is stepped, thereby also forms a ring ladder 91 on fore shell 9, is embedded a liquid-crystalline glasses plate 7 in ring ladder 91, adopts seal 8 sealings around the liquid-crystalline glasses plate 7 and between the fore shell 9.Wherein the trailing flank of liquid-crystalline glasses plate 7 is mutually concordant with the rear end face of fore shell 9, and the cross section size of the rear end face of fore shell 9 is greater than the cross section size of the front end face of back cover 10, when fore shell 9 and back cover 10 are assembled, the rear end face of fore shell 9 is pressed on the outward flange of back cover 10, plays the fixedly effect of back cover 9 inner parts.Also be provided with one at the back side of postnotum 1 and be used to control television set imaging control integrated circuit board 12, LED lamp bar 3 is connected with this control integrated circuit board 12.
The utility model omits the frame structure of original backlight screen, adopts housing of TV set that it is fixed, and has avoided the repetition of television structure, has saved material, has reduced production cost.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these execution modes.Therefore, protection range of the present utility model is limited by appended claims.
