Description
Technical field
The utility model relates to the LCD Technology field, particularly a kind of backlight and LCD.
Background technology
At present, liquid crystal indicator is widely used in electronics, communication and the intelligent electric appliance, and its performance more and more receives publicity.As the part of liquid crystal indicator, the performance of backlight also more and more receives publicity.
Generally, backlight comprises glue frame and backboard, and at present, glue frame and backboard pass through trip, screw, and perhaps, combination is connected trip with screw.Referring to Fig. 1, backlight comprises: glue frame 1 and backboard 2, here, glue frame 1 and backboard 2 are connected by trip.At this moment, glue frame 1 has a bayonet socket 11, and a trip 21 is arranged on the backboard 2, by engaging of bayonet socket 11 and trip 21, realizes being connected of glue frame 1 and backboard 2.Owing to, therefore, when engaging, easily produce chip by the interaction force realization glue frame 1 of trip and engaging of backboard 2.And, when needs are dismantled backlight and are reset, trip repeatedly stressed back distortion, it is loosening to cause glue frame 1 to be connected with backboard 2.In addition, the glue frame occurs stress easily and concentrates at injection moulding bayonet socket place.The reliability that these have all greatly reduced backlight has influenced the performance of backlight.
When glue frame 1 and backboard 2 are connected by screw, need on the correspondence position on glue frame 1 and the backboard 2, punch, then, the screw of packing into connects.Like this, the assembly technology more complicated of backlight not only, and, because screw has certain weight, increased the weight of the weight of backlight, thereby, the performance of backlight influenced.
As seen, the syndeton of glue frame and backboard has certain influence to the performance of backlight in the present backlight, thereby has influenced the performance of liquid crystal indicator.
The utility model content
The utility model embodiment provides a kind of backlight and LCD, in order to improve the performance of backlight.
The utility model embodiment provides a kind of backlight, comprising: glue frame (100), backboard (200), and elastic washer (300), wherein,
Pin (110) on the described glue frame (100) inserts in the pin-and-hole (210) on the described backboard (200) by described elastic washer (300).
The utility model embodiment provides a kind of LCD, comprises above-mentioned backlight.
Among the utility model embodiment, the pin on the glue frame is connected by elastic washer with pin-and-hole on the backboard, and like this, the glue frame in the backlight is not directly to link to each other with backboard, when pin and pin-and-hole engaging, is difficult for producing chip.And, when needs are dismantled backlight and reset, can not make the pin distortion, thereby it is loosening can not cause the glue frame to be connected with backboard, the reliability that this has all improved backlight has greatly promptly improved the performance of backlight, thereby has improved the performance of LCD.

The specific embodiment
Among the utility model embodiment, the glue frame in the backlight is connected by elastic washer with backboard, referring to Fig. 2, backlight comprises: glue frame 100, backboard 200, with elastic washer 300, wherein, pin 110 is arranged on the glue frame 100 and pin-and-hole 210 is arranged on the backboard correspondence position.
Like this, the pin 110 on the glue frame 100 is connected by elastic washer 300 with pin-and-hole 210 on the backboard 200.Be among the utility model embodiment, the pin 110 on the glue frame 100 inserts in the pin-and-hole 210 of backboard 200 by elastic washer 300.
As seen, among the utility model embodiment, pin 110 is not directly to insert in the pin-and-hole 210, but pin 110 engages by elastic washer 300 with pin-and-hole 210.Like this, pin 110 is not directly to contact with pin-and-hole 210, thereby, reduced the friction of pin 110 with pin-and-hole 210, when engaging, be difficult for producing chip.
What adopt in the pin-and-hole 210 of the pin 110 on the glue frame 100 by elastic washer 300 insertion backboards 200 is interference fit, and promptly the internal diameter of elastic washer is less than the external diameter of pin.
In the connection procedure of realizing glue frame 100 and backboard 200, can earlier elastic washer 300 be inserted on the pin 110 of glue frame 100, the pin 110 that will put elastic washer 300 then inserts in the pin-and-hole 210 of backboards 200.
Perhaps, earlier elastic washer 300 is inserted in the pin-and-hole 210 of backboard 200, then, the pin 110 of glue frame 100 inserted is with in the pin-and-hole 210 of glue frame.
Fig. 3 is the profile of elastic washer 300, comprising: madial wall 310, lateral wall 320, first flange 330 and second flange 340.Wherein, the external diameter of first flange 330 is more than or equal to the external diameter of second flange 340.
Like this, when utilizing this elastic washer 300 to realize that glue frame 100 is connected with backboard 200, first flange 330 contacts with a surface of backboard 200, and second flange contacts with another surface of backboard 200, makes elastic washer 300 closely contact with backboard 200.
And the madial wall 310 of this elastic washer 300 contacts with the sidewall of pin 110, and lateral wall 310 contacts with the sidewall of pin-and-hole 210.
Here, the external diameter of first flange 330 is greater than the external diameter of second flange 340.Certainly, in other embodiment, the external diameter of first flange 330 can equal the external diameter of second flange 340.Elastic washer 300 also can have only first flange or second flange.
The stereogram of the elastic washer 300 corresponding with Fig. 3 as shown in Figure 4.Also comprise: comprising: madial wall 310, lateral wall 320, first flange 330 and second flange 340.Wherein, the external diameter of first flange 330 is more than or equal to the external diameter of second flange 340.
Among the utility model embodiment, the material of elastic washer 300 comprises: rubber, Elastic plastic-rubber, or other materials that have elasticity and adhere to specification, because the material feature of elastic washer 300, when repeatedly from the pin-and-hole 210 that is with elastic washer 300, extracting or inserting pin 110, can not make pin 110 distortion yet, can not influence being connected of glue frame 100 and backboard 200 yet.
Among the utility model embodiment, glue frame 100 is general by injection mo(u)lding, and its material comprises: Merlon and glass fibre GF10 and mixture or poly-to stupid dioctyl phthalate glycol ester PET; And backboard 200 is general by punching press, bending and molding, and its material comprises: plated steel sheet EGI or aluminium sheet A1.
Backlight among the utility model embodiment can be applied in the LCD, promptly comprises above-mentioned backlight in the LCD.Certainly, the backlight among the utility model embodiment can also be applied in other the optical instrument.
Among the utility model embodiment, the glue frame in the backlight is not directly to link to each other with backboard, but the pin on the glue frame is connected by elastic washer with pin-and-hole on the backboard, like this, when pin and pin-and-hole engaging, is difficult for producing chip.And, when needs are dismantled backlight and reset,, can not make the pin distortion even repeatedly dismantle and reset, become flexible thereby can not cause the glue frame to be connected with backboard.
In addition, when the mould-injection frame, be easy to form pin, problem of stress concentration can not occur.Therefore, the structure in the foregoing description all easily realizes.
The reliability that these have all improved backlight has greatly promptly improved the performance of backlight, thereby has improved the performance of LCD.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
