Be described in detail in this assembling at display module 50.At first see also Fig. 6 and Fig. 7, Fig. 6 is the exploded perspective view of fixed structure 64 shown in Figure 2 and printed circuit board (PCB) 60, and Fig. 7 is that fixed structure 64 shown in Figure 6 is arranged at the schematic diagram on the printed circuit board (PCB) 60.At first, as shown in Figure 6, be to be formed with a location hole 82 on the printed circuit board (PCB) 60, with usefulness as auxiliary fixed structure 64 location.Then, it is the position that the opening on the fixed structure 64 78 can be aimed at corresponding location hole 82 on the printed circuit board (PCB) 60, and push location hole 82 to along the side of printed circuit board (PCB) 60 with being about to fixed structure 64, till location hole 82 is lived in outstanding structure 72 engagings of first on the substrate 66 of fixed structure 64, thus, as shown in Figure 7, fixed structure 64 can see through the clamping of engaging of location hole 82 on the first outstanding structure 72 and the printed circuit board (PCB) 60 and first bool 68 and 66 pairs of printed circuit board (PCB)s 60 of substrate, thereby firmly is arranged on the printed circuit board (PCB) 60.
Next, see also Fig. 2 and Fig. 3.After being arranged at fixed structure 64 on the printed circuit board (PCB) 60, it is display floater 52 can be arranged on the framework 53, and will encapsulate 54 via chip for driving and be arranged at the side (as shown in Figure 2) of backboard 58 with the printed circuit board (PCB) 60 that is electrically connected on display floater 52; Then, be housing 62 can be gone into toward lower cover from the top of display floater 52, use and backboard 58 common ccontaining display floaters 52 (as shown in Figure 3); At this moment, it is can be as shown in Figure 8 that the assembly of display module 50 inside closes relatively, it is to be the generalized section of Fig. 3 display module 50 along 3-3 ' hatching, as shown in Figure 8, when the common ccontaining display floater 52 of housing 62 and backboard 58, second bool 70 on the fixed structure 64 is to support to arrive in housing 62, housing 62 and 70 of second bools are the tight fit mode to connect, so housing 62 can push second bool 70, so that second bool 70 of fixed structure 64 provide-elastic force of X-direction is to printed circuit board (PCB) 60, printed circuit board (PCB) 60 just can firmly be positioned a side of backboard 58 thus.In other words, see through supporting to arrive between second bool 70 of fixed structure 64 and the housing 62, printed circuit board (PCB) 60 can corresponding change in displacement occur to reach the effect of shock-absorbing buffering with respect to housing 62 under different stressing conditions, that is to say that printed circuit board (PCB) 60 is not a stiff end with engaging of fixed structure 64, thus, can be when display module 50 be subjected to external impacts, reduce chip for driving and encapsulate 54 suffered stress, thereby produce the effect that prevents chip for driving encapsulation 54 fractures.
For instance, if along Fig. 8 ± X-direction double swerve display module 50, then by the crooked shell fragment design of second bool 70 of fixed structure 64, printed circuit board (PCB) 60 will be along with backboard 58 corresponding change in displacement produces the change in displacement of move left and right with respect to housing 62 on ± X-direction, at this moment, also can produce corresponding change in displacement owing to be connected in the display floater 52 of the other end of chip for driving encapsulation 54 because of rocking of display module 50, therefore, at display module 50 in the process of Fig. 8 ± X-direction double swerve, can all corresponding change in displacement can appear because of chip for driving encapsulates 54 two ends, encapsulate 54 suffered external force and make chip for driving encapsulate 54 suffered stress and decline to a great extent, so just can avoid chip for driving to encapsulate the situation generation of 54 torsional deformations even fracture and discharge chip for driving; As if the display module 50 that teetertotters along Fig. 8 ± Y direction, then because second bool 70 of fixed structure 64 has pliability, therefore printed circuit board (PCB) 60 will be along with backboard 58 corresponding change in displacement produces the change in displacement that moves up and down with respect to housing 62 on ± Y direction, similarly, also can produce corresponding change in displacement owing to be connected in the display floater 52 of the other end of chip for driving encapsulation 54 because of rocking of display module 50, so in the process that display module 50 teetertotters along Fig. 8 ± Y direction, chip for driving encapsulation 54 can be because of its two ends all corresponding change in displacement can occur, thereby avoid the situation of torsional deformation even fracture to take place; In like manner, if rock display module 50 along Fig. 8 Z-direction, printed circuit board (PCB) 60 also can have flexual cause because of second bool 70 of fixed structure 64 and produce corresponding change in displacement with respect to housing 62 on Z-direction, therefore, also can reach the above-mentioned effect of avoiding chip for driving encapsulation 54 fractures.
In sum, no matter display module 50 is subjected to the external impacts that makes progress from which side, second bool 70 that printed circuit board (PCB) 60 all can see through fixed structure 64 supports to arrive in the design on housing 62 and produces corresponding change in displacement, and make printed circuit board (PCB) 60 and engaging of fixed structure 64 not be a stiff end, thereby avoid chip for driving encapsulation 54 to take place because of the situation of bearing excessive stress torsional deformation even fracture.
In addition, as shown in Figure 8, be to be formed with one second outstanding structure 84 on the housing 62, it is sticked in second perforation 80 on second bool 70 of fixed structure 64 when being intended to be the common ccontaining display floater 52 of housing 62 and backboard 58, with as the usefulness of auxiliary housing 62 location and reach and make fixed structure 64 can more firmly be arranged at effect between printed circuit board (PCB) 60 and the housing 62.
What deserves to be mentioned is, the outstanding structure 72 of on the said fixing structure 64 first, first perforation, 76 and second perforation 80 are the structures that can be the selectivity configuration, accordingly, the outstanding structure 84 of on location hole 82 on the printed circuit board (PCB) 60 and the housing 62 second also can with omission, to receive the effect of the design of simplifying display module 50.For instance, the location that engages between the structure 84 is given prominence in engage location and second perforation 80 and second that fixed structure 64 can not must see through between the above-mentioned first outstanding structure 72 and the location hole 82, but only utilizes the chucking power between the substrate 66 and first bool 68 to be arranged on the printed circuit board (PCB) 60.In addition, the design of the clamping width between fixed structure 64 upper substrates 66 and first bool 68 is to be not limited to the foregoing description.For instance, the A/F of 68 common accommodation spaces that form of the substrate 66 and first bool can change the height that is designed to greater than the first outstanding structure 72, so printed circuit board (PCB) 60 can insert in substrate 66 and first bool, the 68 formed accommodation spaces more easily, uses shortening fixed structure 64 is arranged at built-up time on the printed circuit board (PCB) 60; In like manner, the A/F of 68 common accommodation spaces that form of the substrate 66 and first bool also can change the height that is designed to equal in fact the first outstanding structure 72.As for adopting which kind of design, look closely display module 50 actual assembled demands and decide.
Next, see also Fig. 9, it is the cut-away section schematic diagram for the utility model one second embodiment one display module 100.Assembly described in second embodiment is numbered identical person with the assembly described in first embodiment, represents that it has similar function or structure, for asking simplified illustration, so repeat no more in this.The design of locating mainly to be bool on the fixed structure that the mentioned display module of the mentioned display module 100 of second embodiment and first embodiment 50 is different.As shown in Figure 9, display module 100 includes display floater 52, chip for driving encapsulation 54, and a circuit board fixing mechanism 102; As shown in Figure 9, circuit board fixing mechanism 102 includes backboard 58, printed circuit board (PCB) 60, and a fixed structure 104.
Then, see also Figure 10, it is the schematic diagram for fixed structure 104 shown in Figure 9.As shown in Figure 10, fixed structure 104 includes a substrate 106 and a bool 108; Substrate 106 has one first end P
1And one second end P
2And be to be formed with an outstanding structure 110 on it, and as shown in Figure 9, then a location hole 112 that is formed with corresponding outstanding structure 110 on the backboard 58, outstanding structure 110 is to be used for being sticked in location hole 112, use the usefulness as positioning and fixing structure 104, in a second embodiment, outstanding structure 110 is preferably to be a circular bump structure; The second end P of substrate 106
2On be to be formed with one to extend chamfering structure 114, and the second end P of counterpart substrate 106 on the bool 108
2An end on also be formed with one accordingly and extend chamfering structure 116, so can see through and extend 114,116 common openings 118 that form of chamfering structure, so that fixed structure 104 can be inserted in and clamp backboard 58 and printed circuit board (PCB) 60 quickly and easily; Bool 108 is the first end P that are connected in substrate 106
1, use being used for and substrate 106 common clamping backboard 58 and printed circuit board (PCB)s 60; In addition, be to be formed with a perforation 120 jointly on substrate 106 and the bool 108, so can see through the design of its hollow structure, use the pliability that increases fixed structure 104.
In addition, if display module 100 desires see through fixed structure 104 to reach the purpose with printed circuit board (PCB) 60 ground connection, then fixed structure 104 can be made up of conductive material, as metal materials such as beryllium copper, phosphorus cyanogen copper, stainless steels, accordingly, backboard 58 also must be made up of conductive material (as metal), thus, the physical characteristic that not only can see through above-mentioned arbitrary metal material is to increase the pliability of fixed structure 104, and display module 100 also can see through the ground connection that fixed structure 104 is finished printed circuit board (PCB) 60 with contacting of backboard 58 simultaneously.
Be described in detail in this assembling at display module 100.See also Fig. 9 and Figure 10.At first, from the above, location hole 112 on the backboard 58 is intended for the usefulness of auxiliary fixed structure 104 location, therefore, it is the position that the opening on the fixed structure 104 118 can be aimed at corresponding location hole 112 on the backboard 58, and then with fixed structure 104 from the bottom side of backboard 58 and printed circuit board (PCB) 60 toward shown in the 9th figure+Y direction upwards clamps backboard 58 and printed circuit board (PCB) 60, till location hole 112 on the backboard 58 is lived in the outstanding structure on the substrate 106 of fixed structure 104 110 engaging, thus, as shown in Figure 9, fixed structure 104 can see through the clamping of engaging of location hole 112 on outstanding structure 110 and the backboard 58 and bool 108 and 106 pairs of backboards 58 of substrate and printed circuit board (PCB) 60, thereby firmly is arranged on backboard 58 and the printed circuit board (PCB) 60.
Thus, see through the assembling that said fixing structure 104 clamps backboard 58 and printed circuit board (PCB) 60 simultaneously, printed circuit board (PCB) 60 can corresponding change in displacement occur to reach the effect of shock-absorbing buffering with respect to backboard 58 under different stressing conditions, that is to say that printed circuit board (PCB) 60 is not a stiff end with engaging of fixed structure 104, thus, can be when display module 100 be subjected to external impacts, reduce chip for driving and encapsulate 54 suffered stress, thereby produce the effect that prevents chip for driving encapsulation 54 fractures.
For instance, as if the display module 100 that teetertotters along Fig. 9 ± Y direction, then by the non-urgent formula Fixed Design of fixed structure 104, printed circuit board (PCB) 60 will produce corresponding change in displacement with respect to backboard 58 on ± Y direction, at this moment, also can produce corresponding change in displacement owing to be connected in the display floater 52 of the other end of chip for driving encapsulation 54 because of rocking of display module 100, therefore, in the process that display module 100 teetertotters along Fig. 9 ± Y direction, can all corresponding change in displacement can appear because of chip for driving encapsulates 54 two ends, encapsulate 54 suffered external force and make chip for driving encapsulate 54 suffered stress and decline to a great extent, so just can avoid chip for driving to encapsulate the situation generation of 54 torsional deformations even fracture and discharge chip for driving; If along Fig. 9 ± X-direction double swerve display module 100, then because printed circuit board (PCB) 60 only is subjected to the free-standing elastic force clamping of fixed structure 104 on ± X-direction, therefore, printed circuit board (PCB) 60 also can produce corresponding change in displacement with respect to backboard 58 on ± X-direction, similarly, also can produce corresponding change in displacement owing to be connected in the display floater 52 of the other end of chip for driving encapsulation 54 because of rocking of display module 100, so at display module 100 in the process of Fig. 9 ± X-direction double swerve, chip for driving encapsulation 54 can be because of its two ends all corresponding change in displacement can occur, thereby avoid the situation of torsional deformation even fracture to take place; In like manner, if rock display module 100 along Fig. 9 ± Z-direction, printed circuit board (PCB) 60 also can have flexual cause because of the bool 108 of fixed structure 104 and produce corresponding change in displacement with respect to backboard 58 on ± Z-direction, therefore, also can reach the above-mentioned effect of avoiding chip for driving encapsulation 54 fractures.
In sum, no matter display module 100 is subjected to the external impacts that makes progress from which side, printed circuit board (PCB) 60 all can see through the non-urgent formula Fixed Design of fixed structure 104 and produce corresponding change in displacement, and make printed circuit board (PCB) 60 and engaging of fixed structure 104 not be a stiff end, thereby avoid chip for driving encapsulation 54 to take place because of the situation of bearing excessive stress torsional deformation even fracture.
