Detailed description of the invention
For ease of understanding, below in conjunction with Figure of description, the backlight that the utility model embodiment provides is described in detail.
Refer to Fig. 1 and Fig. 2; the backlight that the utility model embodiment provides comprises: light guide plate, shading rubber belt 1, diaphragm 2 and cushion 3; wherein; shading rubber belt 1 is arranged at the edge of the exiting surface of light guide plate; diaphragm 2 is arranged at the side that shading rubber belt 1 deviates from the exiting surface of light guide plate; diaphragm 2 is provided with at least one through hole 21, cushion 3 is arranged between shading rubber belt 1 and diaphragm 2, can come out in the subregion of cushion 3 by the through hole 21 on diaphragm 2.
Due in the backlight that provides in the utility model embodiment, diaphragm 2 being provided with at least one through hole 21, comes out in the subregion of cushion 3 by through hole 21.In the process of assembling backlight, at least one suction nozzle of group film machine is corresponding with the through hole 21 on diaphragm 2, and to hold the region that cushion 3 comes out from through hole 21, other suction nozzle holds other regions of diaphragm 2.Therefore, a suction nozzle is had at least can to hold cushion 3.For example; as shown in Figure 1; when diaphragm 2 being provided with three through holes 21; and when group film machine having six suction nozzles; the gettering site of suction nozzle on diaphragm 2 is set to suction nozzle extraction area 4, wherein, the suction nozzle extraction area 4 having three suction nozzles respectively with through hole 21 one_to_one corresponding; the suction nozzle extraction area 4 of other three suction nozzles is positioned at other regions of diaphragm 2, to provide enough suction, diaphragm 2, shading rubber belt 1 and cushion 3 is moved under the drive of suction nozzle along setting track.Because wherein three suction nozzles hold the region that cushion 3 come out by through hole 21; therefore move in the process of diaphragm 2, shading rubber belt 1 and cushion 3 at the suction nozzle of utilization group film machine; cushion 3 and diaphragm 2 can not depart from; thus the side making shading rubber belt 1 contact with cushion 3 can not depart from diaphragm 2, and then improve the efficiency of assembling backlight.
It is worth mentioning that; the quantity of the suction nozzle of group film machine is usually within six; in order to steady mobile diaphragm 2, shading rubber belt 1 and cushion 3; the absorption position of suction nozzle on diaphragm 1 should be even; therefore draw and be preferably one to four in the quantity of the suction nozzle of cushion 3 opposed area, then the quantity of the through hole 21 on diaphragm 2 is preferably less than or equals four.
Through hole 21 in said protection film 2 cushion 3 the shape of projection in the plane do not limit; it can be regular shape; as circle, rectangle or ellipse; also can be that other are irregularly shaped; in order to easy to process, through hole 21 cushion 3 the shape of projection be in the plane preferably circular, rectangle or ellipse.
When the shape of through hole 21 is circular, the diameter of circular through hole 21 can be greater than, be equal to or less than the internal diameter of suction nozzle, when the diameter of through hole 21 is more than or equal to the internal diameter of suction nozzle, corresponding suction nozzle stretches in through hole 21, directly contacts with cushion 3, after air in suction nozzle is extracted out, air pressure in the cavity formed between suction nozzle and cushion 3 is less than the air pressure of its outside, and therefore, cushion 3 can hold by suction nozzle, after control suction nozzle moves, suction nozzle drives cushion 3 to move together.When the diameter of through hole 21 is less than the internal diameter of suction nozzle; suction nozzle directly contacts with diaphragm 2; when being extracted out by the air in suction nozzle, the air pressure in the cavity make suction nozzle, forming between diaphragm 2 and cushion 3 is less than the air pressure of its outside, and therefore cushion 3 and diaphragm 2 hold by suction nozzle simultaneously.In order to avoid the cavity of suction nozzle, formation between diaphragm 2 and cushion 3 exists the gap be communicated with cavity space outerpace, preferably, through hole 21 is positioned on cushion 3 in the projection of cushion 3 place plane.Design like this, suction nozzle, the air of cavity outside formed between diaphragm 2 and cushion 3 can not enter cavity from diaphragm 2 and the gap of cushion 3, and therefore suction nozzle can not depart from from cushion 3 and diaphragm 2.
Move in the process of diaphragm 2, shading rubber belt 1 and cushion 3 at the suction nozzle of utilization group film machine; cause cushion 3 that comparatively large deformation occurs in order to avoid the suction due to suction nozzle acts on cushion 3 completely; please continue to refer to Fig. 1; in a preferred embodiment; through hole 21 through hole is circular port, and the diameter of through hole 21 is less than the internal diameter of the suction nozzle of group film machine.Design like this, suction nozzle directly contacts with diaphragm 2, and the air pressure in the cavity when being extracted out by the air in suction nozzle, make suction nozzle, forming between diaphragm 2 and cushion 3 is less than the air pressure of its outside, and therefore cushion 3 and diaphragm 2 hold by suction nozzle simultaneously.Now, the suction of suction nozzle can not act on cushion 3 completely, and the suction that cushion 3 is subject to reduces, thus the deformation quantity of the cushion 3 when utilizing suction nozzle to move diaphragm 2, shading rubber belt 1 and cushion 3 is reduced.
It is worth mentioning that, above-mentioned cushion 3 can be arranged on the shading rubber belt 1 corresponding with the edge of the exiting surface of light guide plate, or, cushion 3 can only be arranged on the shading rubber belt 1 corresponding with the side of light guide plate, such as, as shown in Figure 1, cushion 3 is arranged on the shading rubber belt 1 corresponding with the incident side of light guide plate.Compared with being arranged on the shading rubber belt 1 corresponding with the edge of the exiting surface of light guide plate with cushion 3, when cushion 3 is arranged on the shading rubber belt 1 corresponding with the incident side of light guide plate, the gross weight of cushion 3 reduces, after backlight has been assembled, cushion 3 reduces the pressure of the shading rubber belt 1 be positioned at below it, thus alleviates the distortion of shading rubber belt 1.It should be noted that, above-mentioned cushion 3 can be rubber layer or polyester resin layer, is preferably polyester resin layer, because polyester resin layer rub resistance and buffering effect are better, thus is extended in the service life of cushion 3.
The utility model embodiment additionally provides a kind of display unit simultaneously, comprises the backlight described in above-described embodiment.The Dominant Facies that described display unit and above-mentioned backlight have relative to prior art is same, does not repeat them here.It should be noted that, above-mentioned display unit can be: any product or parts with Presentation Function such as display floater, Electronic Paper, mobile phone, panel computer, television set, notebook computer, DPF, navigator.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
