Description

The unitized construction of LCD

(1) technical field

The utility model relates to a kind of unitized construction, is applied to LCD.

(2) background technology

As shown in Figure 1, at present, the unitized construction of LCD is made up of liquid crystal panel and preceding frame, and preceding frame is to make according to the liquid crystal panel of different size, therefore, during fabrication, need to make the preceding frame of multiple different size, and the preceding frame of each size that must hoard some, in order to follow-up assembling when obtaining order, but the design of the unitized construction of this kind LCD but causes production cost to increase (the die sinking cost that needs the preceding frame of each size), cost of inventory increases (need hoard the stock of the preceding frame of each size), the production time process increases and production efficiency reduces (when the preceding frame of no a certain size, need wait to expect).

Based on this, design a kind of unitized construction of LCD, in the hope of can mating the different size liquid crystal panel, and solve the aforesaid drawbacks.

(3) utility model content

Fundamental purpose of the present utility model is for a kind of unitized construction of LCD is provided, and shortening the production time process, to reduce and produce and hoard cost, and enhances productivity.

The unitized construction of the LCD shown in the utility model includes backboard, preceding frame and cover frame, its dorsulum includes the array keeper with respect to the liquid crystal panel size of LCD, and combine with preceding frame, to form the accommodation space of tolerable installing liquid crystal panel, and should have the window that exposes liquid crystal panel by preceding frame, as for overlapping the window that frame then is arranged at preceding frame, just can cover the edge of liquid crystal panel, and include one group of keeper of relative backboard.During assembling, size according to liquid crystal is placed in wherein one group of space that keeper limited of backboard with it earlier, then backboard is combined with preceding frame, frame combines with the cover frame before making again, thus, the cover frame just can cover the edge of liquid crystal panel, and immobile liquid crystal panel, so fixed size in preceding frame, and the cover frame just can cover under the situation at edge of liquid crystal panel (cover frame can according to the dimension modifying of liquid crystal panel), only need make the preceding frame of same size, arrange in pairs or groups the again cover frame of different size, can make the LCD of different size, so the unitized construction of this kind LCD is to shorten the time course of production LCD, reduce production and cost of inventory and enhance productivity.

The unitized construction of LCD of the present utility model can reach following effect:

1. because the die sinking expense of preceding frame is higher, therefore, can reduce production costs to make LCD with the cover frame (the die sinking expense is lower) of the inner rim of identical preceding frame collocation different size.

2. because of making the LCD of different size with the preceding frame of same size, thus do not need to hoard the preceding frame of different size, and can reduce cost of inventory.

3. when the order of the LCD of obtaining different size, because preceding frame is measure-alike, thus need not wait to expect, thereby can shorten the production time process, enhance productivity.

For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

Fig. 2 is the exploded view of the utility model LCD;

Fig. 3 is the constitutional diagram of the utility model LCD; And

Fig. 4 A, 4B are the sectional view of the utility model LCD cover frame with respect to the liquid crystal panel of different size.

(5) embodiment

Shown in Fig. 2, Fig. 3 and Fig. 4 A, 4B, according to the unitized construction of the LCD shown in the utility model, include backboard 10, preceding frame 20 and cover frame 30, its dorsulum 10 combines with preceding frame 20, to form the accommodation space of tolerable installing liquid crystal panel 40.

Backboard 10 includes array keeper 11 and projection 12, and wherein keeper 11 is arranged at backboard 10, and is arranged in accommodation space, and each organizes keeper 11 respectively with respect to liquid crystal panel 40 edges of different size, and projection 12 then is arranged at the limit end of backboard 10.

Preceding frame 20 combines with backboard 10, to form the accommodation space of tolerable installing liquid crystal panel 40, this accommodation space be can ccontaining liquid crystal panel 40 full-size, and preceding frame 20 has window 21 and the blind hole 22 of exposing liquid crystal panel 40, wherein window 21 includes combined hole 211, and blind hole 22 is arranged at the limit end of preceding frame 20, and corresponding to projection 12, so that preceding frame 20 combines with backboard 10.

Cover frame 30 just can cover the edge of liquid crystal panel 40, and immobile liquid crystal panel 40 (the cover frame 30 of different size is the liquid crystal panel 40 that cooperates corresponding size respectively), and cover frame 30 comprises one group of keeper 31 and hot melt part 32, keeper 31 is with respect to wherein one group of keeper 11 of backboard 10, liquid crystal panel 40 is fixed in

keeper

11,31 spaces of being limited, and keeper 31 includes blind hole 311, so that an end of keeper 11 is installed in this

blind hole

311,32 of hot melt parts are with respect to combined hole 211, to utilize hot melting way, cover frame 30 is combined with preceding frame 20.

As shown in Figures 2 and 3, when assembling, elder generation is according to the size of liquid crystal panel 40, it is seated in wherein one group of space that keeper 11 is limited of backboard 10, then backboard 10 is combined (by projection 12 and blind hole 22) with preceding frame 20, again blind hole 311 is together combined (frame 20 combines with cover frame 30 before making) with combined hole 211 with keeper 11 with hot melt part 32, thus, cover frame 30 just can cover the edge of liquid crystal panel 40, and the immobile liquid crystal panel.

Certainly, the combination of above-mentioned

keeper

11,31 also can change to keeper 11 and comprise a blind hole, and an end of keeper 31 is installed in this blind hole, or being same as projection 12 also can with the combination of blind hole 22, on the other hand, the combination of backboard 10 and preceding frame 20 also can change to blind hole and be arranged at backboard 10, and projection is arranged at the combination of preceding frame 20.

Based on above-mentioned, preceding frame 20 is of a size of fixing, and cover frame 30 just can cover under the situation at edge of liquid crystal panel 40 (cover frame 30 can according to the dimension modifying of liquid crystal panel 40), only need make the preceding frame 20 of same size, arrange in pairs or groups the again cover frame 30 of different size, can make the LCD of different size, so the unitized construction of this kind LCD can shorten production time process, reduction production and cost of inventory and enhance productivity.

[effect of reaching]

3. when the order of the LCD of obtaining different size, because preceding frame is measure-alike, thus need not wait to expect, thereby can shorten the production time-histories, promote production efficiency.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
