Abstract
The utility model discloses a fixing structure of a liquid crystal display (LCD) screen. The LCD screen comprises an LCD screen, a backlight plate and a printed circuit board (PCB), wherein the LCD screen, the backlight plate and the PCB are arranged inside an outer shell in sequence. The LCD screen is connected with the PCB in an electric mode through conductive adhesive tape. The PCB is fixed on the outer shell through screws. Pressing strips are arranged at two ends of the rear portion of the backlight plate. The backlight plate and the LCD screen are fixed on the outer shell through the pressing strips. The fixing structure of the LCD display screen has the advantages that electric signals can be stably transmitted amount the fixing structures of the LCD screen, the structure is simple, size is small, and maintenance is convenient.
Description
Technical field
The utility model relates to a kind of fixed sturcture of LCD display.
Background technology
LCD display belongs to liquid crystal type and shows, generally, between the pcb board of LCD display and LCD screen by conductive adhesive tape and metal electrode transmission of electric signals.
Can increase volume when using metal electrode, maintenance difficult can't be keeped in repair in case LCD has fault to change, but the electric signal transmission is reliable.
When using conductive adhesive tape, reduce volume greatly, and be convenient to maintenance.Yet conductive adhesive tape needs outer force compresses could guarantee its good contact, causes the LCD screen to damage if the pressure of conductive adhesive tape is crossed conference, and pressure is too small can to cause loose contact; So structurally need remove to guarantee the compress variation of conductive adhesive tape with structural member, the thing of exerting pressure of conductive adhesive tape is the pcb board that golden finger (conductive contact) arranged.
At present, the back of LCD screen is close to a backlight more smaller than LCD, and the area of general pcb board is bigger than the LCD screen, by the fixing screw of PCB (perhaps buckle) remove to compress conductive adhesive tape, fixedly backlight and LCD shield.A lot of small sizes or large-sized LCD screen and backlight adopt the fixed form that suspends, and remove to control the compression degree of conductive adhesive tape with the degree of tightening of gib screw.Simplicity of design, volume are little like this, but contact unreliablely, and as time passes, the conductive adhesive tape compression can occur inhomogeneous, causes loose contact.
The utility model content
The purpose of this utility model is the defective that exists at above-mentioned prior art, proposes a kind of fixed sturcture of LCD display.
The technical solution adopted in the utility model is, design a kind of fixed sturcture of LCD display, described display screen comprises LCD screen, backlight and the pcb board of installing successively in the enclosure, described LCD screen and pcb board are electrically connected by conductive adhesive tape, described pcb board is screwed on shell, be arranged on the press strip at two ends, backlight rear portion, this press strip is fixed on backlight and LED screen on the shell.
In one embodiment, described press strip two ends are provided with pilot hole, and described shell is provided with the projection that cooperates pilot hole.
Compared with prior art, the utility model uses briquetting that LCD screen and backlight are fixed together reliably, and can control the decrement of conductive adhesive tape when connecting, guarantee stable being electrically connected between LCD screen and the PBC plate, simple in structure, stable signal transmission is strong, and volume is little, is convenient to dismounting and maintenance.

Embodiment
Below in conjunction with drawings and Examples utility model is described in detail.
Shown in Fig. 1,4, the fixed sturcture of a kind of LCD display that the utility model proposes, comprise: be installed in LCD screen 2, backlight 4 and pcb board 3 in the shell 1 successively, the two ends of LCD screen 2 are provided with conductive electrode 5, and pcb board 3 is electrically connected conductive electrode 5 by conductive adhesive tape 6, and pcb board 3 usefulness screws 7 are fixed on the shell 1, two ends, backlight 4 rear portion arrange press strip 8, press strip 8 is fixed on backlight and LED screen on the shell, and press strip 8 two ends are provided with pilot hole 9, and shell 1 is provided with the projection that cooperates pilot hole.
Shown in Fig. 2,3, during installation, LCD screen 2 is fastened on the front end face of shell, connect backlight 4, use press strip 8 to cooperate projection fixed L CD screen 2 and backlight 4, use conductive adhesive tape 6 to connect conductive electrode and pcb board then, at last, by screw 7 pcb board is fixed on enclosure.In the screw-driving process, pcb board is close on the briquetting 8, simultaneously conductive adhesive tape 6 compressions is fixed between conductive electrode 5 and the pcb board.
In the utility model, the thickness of briquetting 8 can arrange according to the expectation compression degree of conductive adhesive tape 6, the stable connection between so just guaranteeing pcb board and LCD shielding.
Above-described embodiment only is used for explanation embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
