Abstract

The utility model relates to a liquid crystal displayer framework which comprises U- shaped units whose both ends are connected sequentially. The two U-shaped units constitute a hollow frame. The utility model has the advantages of saving material and reducing cost.

Description

LCD frame

Technical field

The utility model relates to a kind of LCD frame.

Background technology

LCD is as a kind of flat-panel screens, because of it has frivolous, advantage such as brightness is high, in light weight and little power consumption, and is widely used in various demonstrations field.Usually, LCD comprises that one is used for the display panel and of display frame for this display panel provides the module backlight of planar light, and utilizes the LCD frame of a metal material to cooperate with a glue frame to accommodate and fix this display panel and this module backlight.

Fig. 1 to Fig. 3 is a kind of manufacturing step synoptic diagram of prior art LCD frame.Step 1 cuts a metal coiled material (figure does not show), thereby forms a rectangular metal sheet material (figure does not show); Step 2, the pin place, four limits of punching/this metal sheet of side cut as shown in Figure 1, thereby all around forms the wide outer side edges of the fourth class 12 at a rectangle plane 11; Step 3 as shown in Figure 2, bends this side 12 all round along same direction, makes its vertical this rectangle plane 11; Step 4, this rectangle plane 11 of punching, thus forming a display window 14 at the middle body of this rectangle plane 11, this display window 14 can expose display panel; Step 5 is utilized the interface of laser welding technology involution two adjacent outer side edges 12, thereby forms LCD frame 10 as shown in Figure 3.

Yet, because in the process of making this LCD frame 10, thereby the full wafer metal sheet need be removed its middle body material via punching/methods such as side cut and be formed this display window 14, unrenewable this LCD frame 10 of making of removed middle body material, and the material area that formation display window 14 is removed accounts for 2/3rds of whole metal sheet, therefore, this LCD frame 10 waste of material in manufacture process is serious, causes its manufacturing cost higher.

The utility model content

In order to solve the serious problem of LCD frame waste of material in manufacture process in the prior art, be necessary to provide the higher LCD frame of stock utilization in a kind of manufacture process.

A kind of LCD frame, it comprises the U-shaped unit material that two ends connect successively, this two U-shapeds unit material constitutes a hollow framework.

Compared with prior art, because when cutting this LCD frame of formation, can on a sheet material, form the staggered in twos U-shaped unit material of arranging relatively, thereby the sheet material area between each U-shaped unit material is utilized effectively, thereby make full use of the material area of sheet material, effectively save the waste of material in manufacture process, reach the purpose that reduces cost.

Fig. 4 is the structural representation of the utility model LCD frame first embodiment.

Fig. 5 is the structural representation of the utility model LCD frame second embodiment.

Fig. 6 and Fig. 7 are the floor map that one of each embodiment of the utility model LCD frame cuts mode.

Embodiment

Fig. 4 is the structural representation of the utility model LCD frame first embodiment.This LCD frame 20 is to dock a hollow framework that constitutes by U-shaped unit material 210,211 ends of two symmetries.This hollow space is as the display window 220 of LCD, and its area is slightly less than the display panel area of this LCD.This U-shaped unit material 210,211 comprise respectively be parallel to each other and two side arms 212,213 that length is identical and with these two side arms 212,213 linking arms 214 connected vertically.This two side arms 212,213 and this linking arm 214 include a horizontal component (not label) parallel with this display panel and one and the vertical part (not label) of this horizontal component vertical connection, this display window 220 of the end to end formation of this horizontal component, this vertical portion partial width is identical, and its width is substantially equal to each module thickness sum of this LCD.

Fig. 5 is the structural representation of the utility model LCD frame second embodiment.The structure of the LCD frame 20 of this LCD frame 30 and first embodiment is basic identical, its difference is: the two side arms 312,313 of this two U-shapeds unit material 310,311 is uneven in length, during butt joint, the longer side arm 312 of a U-shaped unit material 310 connects with the shorter side arms 313 of another U-shaped unit material 311.

The unit material of above-mentioned

LCD frame

20,30 can utilize laser welding technology to engage when butt joint, thereby makes each unit material constitute an integral body.And, a concave surface and convex surface that the composition surface of two unit materials that dock mutually can be a flat face, an inclined-plane, a huge flank of tooth, a wavy surface or matches.

Seeing also Fig. 6 and Fig. 7, is the floor map of the mode that cuts of the utility

model LCD frame

20,30 each embodiment.When two U-shaped unit materials of the

LCD frame

20,30 that cuts above-mentioned two embodiments, can on a sheet material 40, form as Fig. 6 or the staggered in twos U-shaped unit material of arranging relatively shown in Figure 7.Owing to adopt this kind to cut mode, the sheet material area between each U-shaped unit material two side arms is utilized effectively, thereby makes full use of the material area of sheet material 40, effectively save the waste of material in the manufacture process, reach the purpose that reduces cost.

Claims

1. LCD frame, it is characterized in that: this LCD frame is a hollow framework that is made of the two U-shaped unit materials that end connects successively.

2. LCD frame as claimed in claim 1 is characterized in that: this two U-shapeds unit material is symmetry relatively.

3. LCD frame as claimed in claim 1 is characterized in that: this U-shaped unit material comprises two side arms and and this two side arms linking arm connected vertically that is parallel to each other.

4. LCD frame as claimed in claim 3 is characterized in that: the length of this two side arms is inequality.

5. LCD frame as claimed in claim 3 is characterized in that: this side arm and this linking arm comprise that respectively one is parallel to a horizontal component and one and this horizontal component vertical part connected vertically of display panels.

6. LCD frame as claimed in claim 1 is characterized in that: the end of two U-shaped unit materials is flat face, inclined-plane, serrated face, the wavy surface of relative bonding or a concave surface and the convex surface of working in coordination.
