In the present embodiment, above-mentioned LCD also comprises locating device, and this locating device comprises the through hole that is located on the housing 4, and the register pin that can run through described through hole.This register pin is pluggable, like this after display panels 1 shifts out the zone of module correspondence backlight, just can in described through hole, insert above-mentioned register pin, and this register pin can contact with the lower limb of display panels 1 or the block on its side, thereby comes its position is fixed to the display panels power of providing support.
The realization of register pin except can adopting above-mentioned pluggable design, thereby can also be connected to the framed integrative-structure that go up to form of module backlight by an elastomeric element.To be specifically introduced this integrative-structure below, and be that example is done further the LCD that provides in the present embodiment and elaborated with this implementation.
Border circular areas among Fig. 1 amplified obtain Fig. 3, and in conjunction with Fig. 2, then therefrom can see: corresponding to the through hole on the housing 4, LCD in the present embodiment is provided with depressible register pin 11, this register pin 11 is framedly gone up (framed structure clearly is not shown) by what an elastomeric element was fixed to module 2 backlight in Fig. 3, in the present embodiment, described elastomeric element is the spring 12 among Fig. 3, the one end is fixed on the register pin 11, and the other end is fixed on module 2 backlight framed; And, be equipped with two blocks 13 (failing among the figure all to illustrate) that are used for fixing the position of described display panels 1 in the left and right sides of described display panels 1.This block 13 can be the side that is formed directly into described display panels 1 by cutting technique, also can be by adhesion technique block 13 to be fixed on the side of described display panels 1.If be coated with frame around the display panels 1, described block 13 can also be arranged on the left and right sides of described frame so.
As shown in Figure 4, the horizontal cross-section of register pin 11 can be " in " font, perhaps " protruding " font of Qing Xieing, wherein protruding the position is a supporting surface, this supporting surface combines with block 13 and can fix the position of display panels 1.In order to guarantee the stability after described display panels 1 carries out stationkeeping, this supporting surface can be the horizontal support face, also can be acclivitous supporting surface (if, being easy to generate slip between register pin 11 and the block 13 downwards).In the description of present embodiment back, be that example describes the LCD that the utility model embodiment provides all with the horizontal support face.Exposed end at described register pin 11 can be simply cylindrical, also can be sphere shape, polygon etc. other be convenient to the shape that grasps and push.
Above-mentioned register pin 11 and block 13 are combined, just can adjust the position of display panels 1; Particularly, as shown in Figure 3, (both be not compressed in the raw at spring 12, be not stretched yet) or during the mild compression state, horizontal support face in the vertical direction on block 13 and the register pin 11 is just in time corresponding up and down, then block 13 can screens on described horizontal support face, this moment display panels 1 stationkeeping; And when spring 12 was in degree of depth compressive state, as shown in Figure 5, the horizontal support face in the vertical direction on block 13 and the register pin 11 just in time staggered, and display panels can move along the chute direction.In the present embodiment, the shape of described block 13 also can be diversified, and as shown in Figure 6, block 13 can be selected for use but be not limited to the shape shown in Fig. 6 certainly; But, no matter adopt which kind of shape, be will be perpendicular to the side of described display panels 1 away from a side of display panels 1 moving direction on the block 13, block 13 screens stably is on the horizontal support face of register pin 11 like this.
In Fig. 2, can see, between described display panels 1 and module backlight 2, be provided with dustproof brush 14, should shift out an end of direction by the dustproof brush 14 close display panels 1 that are positioned at module 2 backlight, and the bristle of the brush 14 that should prevent dust is against on the described display panels 1; Like this, when display panels 1 was back into normal condition, dustproof brush 14 can be inswept from the back side of display panels 1, prevents that the accumulation dust influences the quality that video shows on the display panels 1.
Under normal circumstances, as shown in Figure 2, block 13 screens on the top, side of display panels 1 on the horizontal support face of register pin 11, this moment display panels 1 and module backlight 2 the position over against; The light that module 2 backlight sends is directly injected display panels 1, and the vision signal of outside input is input in the display panels 1 after the transmission of printed circuit board (PCB) 8 and flexible PCB 5 simultaneously, thereby realizes the function that vision signal shows.
When the LCD that provides in the present embodiment need realize its illumination functions, as shown in Figure 7, press described register pin 11 from the outside, horizontal support on the register pin 11 is moved towards LCD is inner, and then block 13 in the vertical directions on this horizontal support face and display panels 1 side are staggered, display panels 1 just can freely move up and down like this.Upwards spur described display panels 1 by external force, it is moved up along chute 3; Described external force can be by artificially manually providing, and also can be to provide by propulsion system.In the process that described display panels 1 moves up, affect connected flexible protective film 6 also to move up, its part that is wrapped on the spool 7 is extracted out from spool; When the block 13 of bottom, display panels 1 side arrives the position corresponding with register pin 11; cancelling the external force of pushing register pin 11 makes spring 12 be returned to state of nature; this moment as shown in Figure 8; block 13 screens of the bottom, side of display panels 1 are on the horizontal support face of register pin 11, and the flexible protective film 6 that trails is just over against backlight module 2.The light that backlight module 2 sends sees through transparent flexible protective film 6 directive LCD outsides, thereby realizes the effect of its illumination; Here, owing to be provided with flexible protective film 6, thereby make the dust of LCD outside can not adhere on the backlight module 2 and then influence illuminating effect.
When display panels 1 moved up, connected flexible PCB 5 was also affecting printed circuit board (PCB) 8 to move up; Because flexible protective film 6 all is to be wrapped on the spool 7 with the connecting line 9 that links to each other with printed circuit board (PCB); therefore can both successfully extract out from spool 7 for flexible protective film 6 and connecting line 9, flexible protective film 6 is identical with the winding direction of connecting line 9 on spool 7.
Consider that flexible protective film 6 has certain thickness, its winding radius reality on spool 7 is greater than the radius of spool 7 self, and when spurring flexible protective film 6 and connecting line 9 so simultaneously, both actual upwards height of pulling are not wait; Bring the inconvenience of operation for fear of this situation, also the setting of connecting line 9 can be connected on the spool 7, but directly connect an elastomeric element independently, thereby provide downward pulling force for printed circuit board (PCB) 8.
For the light that can allow backlight module 2 send passes through described flexible protective film 6 smoothly, so flexible protective film 6 should be transparent; And flexible protective film 6 can be a water white transparency completely, and can certainly have certain color or drafting has different pattern, to satisfy the demand of different illuminating effects; And the material of flexible protective film 6 can be selected for use but be not limited to plastics or resin.In addition; in the present embodiment; the thickness of flexible protective film 6 is identical with the thickness of display panels 1; like this when flexible protective film 6 is taken over display panels 1 and is entered chute 3; can there be the slit between the border of flexible protective film 6 and chute 3, so just can stops dust to enter into the inside of LCD by side seam well yet.
In the utility model embodiment, but spool 7 spool of elastic reset preferably.
When display panels 1 being moved back into module backlight 2 corresponding regions, be to press described register pin 11 from the outside equally, horizontal support on the register pin 11 is moved towards LCD is inner, and then block 13 in the vertical directions on this horizontal support face and display panels 1 side are staggered, display panels 1 just can freely move up and down like this.Promote described display panels 1 downwards by external force, it is slowly moved down along chute 3; This moment flexible protective film 6 and connecting line 9 to be subjected to external pull less, but the spool 7 of elastic reset will spur described flexible protective film 6 and connecting line 9, and it is rewinded on the spool.When the block 13 on top, display panels 1 side arrives the position corresponding with register pin 11, cancelling the external force of pushing register pin 11 makes spring 12 be returned to state of nature, LCD is returned to state shown in Figure 2 again, block 13 screens on the top, side of display panels 1 are on the horizontal support face of register pin 11, display panels 1 and backlight module 2 over against, the LCD of this moment can be carried out the function that its video or image show again.
In order further to reduce the possibility that backlight module 2 is subjected to contamination by dust, the surface of the chute 3 among the utility model embodiment is through MoST
TMThe surface-treated of lubricating and wear-resisting coating such as (a kind of self-lubricating solid coating), pb-sn alloy plating, nickel-phosphorus coating or coating, perhaps the surface of chute 3 adopts PTFE low-friction coefficient materials such as (teflon) to prepare; Like this, when display panels 1 slides, can not produce Particle (dust) in chute 3 because of surface abrasion.
The LCD that the utility model embodiment provides, its under general state described display panels and described module backlight over against, this moment, described LCD can be used for showing the vision signal of input; After described display panels is shifted out the zone of module correspondence backlight by described chute, then described LCD can be used for illumination, and the light that sent by described module backlight this moment need not to pass through display panels again, so its illuminating effect also is greatly improved; The LCD that the utility model embodiment provides is when making lighting use, and the light intensity of its illumination is 11 times of the common liquid crystals display, and can protect backlight not destroyed by dust, keeps the excellent results that shows.
In the description of drawings and Examples of the present utility model, only be that to carry out the mobile of vertical direction with the display panels with LCD be example, in actual implementation procedure, also the display panels of LCD can be carried out moving of horizontal direction, only chute need be arranged on the both sides up and down of LCD this moment, and described spool to be arranged on the left side or the right side of LCD.
