This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0101216, filed on Aug. 2, 2021, which is hereby incorporated by reference as if fully set forth herein.
The present disclosure relates to a display module and a display apparatus including the same, and more particularly, to a display module having a structure with improved durability and a display apparatus including the same.
Contents described in this Background section simply provide background information about the present disclosure and do not constitute the prior art.
As we enter a full-fledged information era, a display apparatus that visually expresses an electrical information signal has developed rapidly. In response thereto, various display apparatus having excellent performance, thinness, light weight, and low power consumption have been developed.
The display apparatus include a liquid crystal display apparatus (LCD), a quantum dot (QD) display apparatus, a field emission display apparatus (FED), an electro-wetting display apparatus (EWD), and an organic light-emitting display apparatus (OLED), etc.
The display apparatus is miniaturized so that the apparatus may be carried by a user. The display apparatus has been developed to be mounted on a movable apparatus such as a vehicle. Thus, the user may use the display apparatus on the vehicle more conveniently.
For convenience of a user, development of a display apparatus having a roll-up structure is active. Such roll-up display apparatus and a display module included therein may have a roll-up display of a flexible structure that is bent.
In one example, the display may be formed in a structure having a plurality of layers in which components having different functions are stacked on each other. The bending may occur continuously and repeatedly by use of the roll-up display. Due to such bending, adhesion between the layers of the display having the stack structure is degraded, so that a peeling phenomenon in which the layers are separated from each other may occur.
In particular, a cover glass disposed in the display has a predefined thickness and has a relatively great elastic force. Therefore, in the case of bending, adhesion with other layers may be more easily degraded by repulsion due to such elastic force, so that the cover glass may be easily peeled.
In particular, the peeling phenomenon is relatively highly likely to occur at a lower end of the display where bonding between the layers forming the display ends. The peeling that occurred at the lower end of the display may gradually spread to a center of the display due to the continuous use of the display apparatus.
Such peeling phenomenon may cause a malfunction or a failure of the display. A solution to such problem is required.
Further, an apron that supports the display in the display apparatus and guides an operation may be attached to the display. Due to the continuous and repetitive bending of the display, adhesion between the display and the apron at the lower end of the display may be degraded, which may cause a separation between the display and the apron. Thus, the malfunction or the failure of the display may occur. A solution to such problem is required.
Accordingly, a purpose of the present disclosure is to provide a display module having a structure capable of suppressing an occurrence of a peeling phenomenon in a display that contains a flexible material and has a structure of being bendable.
In addition, a purpose of the present disclosure is to provide a display module having a structure that suppresses an occurrence of a peeling phenomenon at a lower end of a display and a display apparatus including the same.
In addition, a purpose of the present disclosure is to provide a display module having a structure that may suppress separation resulted from degradation of adhesion between a display and an apron at a lower end of the display and a display apparatus including the same.
In addition, a purpose of the present disclosure is to provide a display module having a structure capable of stably mounting a printed circuit board having a driving circuit and a display apparatus including the same.
Purposes of the present disclosure are not limited to the above-mentioned purpose. Other purposes and advantages of the present disclosure that are not mentioned may be understood based on following descriptions, and may be more clearly understood based on embodiments of the present disclosure.

A display apparatus including a display module 10 according to an embodiment may be mounted on a mobile apparatus such as a vehicle to provide convenience to a user. Hereinafter, a display apparatus mounted on a dashboard of the vehicle will be described by way of example.
The display apparatus according to an embodiment may include, for example, a liquid crystal display apparatus (LCD), a quantum dot (QD) display apparatus, a field emission display apparatus (FED), an electrowetting display apparatus (EWD), and an organic light-emitting display apparatus (OLED), etc. However, the present disclosure is not limited thereto.
The apron 200 may have a structure in which at least a portion thereof is deformable so that at least a portion thereof may move integrally with the display 100. Each of the display 100 and the apron 200 may be constructed such that at least a portion thereof slides in the first direction. That is, each of the display portion 100 and the apron 200 may be constructed such that at least a portion thereof ascends and descends with respect to the display apparatus.
The display apparatus may include a housing 20 to accommodate therein at least a portion of the display 100 and at least a portion of the apron 200. When the display 100 and the apron 200 move downward, at least a portion of each of the display 100 and the apron 200 may be bent and deformed to a curved shape when viewed from a side and thus may be accommodated in the housing 20.
In this regard, each of the display 100 and the apron 200 may be constructed such that at least a portion thereof is wound around a rolling guide 30 disposed in the display apparatus. Accordingly, the display 100 and the apron 200 may be continuously and repeatedly deformable.
In one example, a protective film 101 for protecting the display 100 may be attached to a front face of the display 100. For example, the protective film 101 may be formed as a scattering preventing film that prevents the display 100 from being broken into pieces and scattering by an external impact to protect a user.
The display 100 may be formed in a plate shape, and may include a cover glass and a panel attached to one face of the cover glass and reproducing an image or a video.
In addition, the display 100 may be formed in a structure in which a polarizer, a back plate irradiating light to the panel, and various adhesives for bonding the above-described components to each other are stacked.
Because the display 100 of an embodiment has a structure wound around the rolling guide 30, that is, a rolling structure, bending may occur continuously and repeatedly. Due to such bending, adhesion between layers of the display 100 having the stacked structure is degraded, so that a peeling phenomenon in which the layers are separated from each other may occur.
In particular, because the cover glass has a predefined thickness and has a relatively great elastic force, when being bent, the cover glass may be easily peeled as adhesion with other layers is more easily degraded by repulsion resulted from such elastic force.
Such peeling phenomenon may cause a malfunction or a failure of the display 100. Further, it may be difficult for the display 100 to be accommodated in the housing 20 while sliding due to such peeling phenomenon.
In addition, when the peeling phenomenon occurs, friction resulted from interference between the housing 20 and the display 100 occurs, thereby further shortening a lifespan of the display module 10 and the display apparatus including the same.
In particular, there is a relatively high possibility that the peeling phenomenon occurs at a lower end of the display 100 where the bonding between the layers forming the display 100 ends. Because the bending does not occur at an upper end of the display 100 in the display module 10 according to an embodiment, the possibility of peeling is relatively lower than that of the lower end of the display 100.
The peeling that occurred at the lower end of the display 100 may gradually spread to a center of the display 100 due to continuous use of the display apparatus.
Accordingly, an embodiment provides the display module 10 having a structure that suppresses the occurrence of the peeling at the lower end of the display 100 and a display apparatus including the same.
The display module 10 may further include a printed circuit board 300 having a driving circuit for controlling an operation of the display 100. The printed circuit board 300 may be electrically connected to the display 100, and may include a plurality of boards and connectors for connecting the plurality of boards to each other. In this regard, the driving circuit may be distributed on all or some of the boards and the connectors.
The printed circuit board 300 may include a first board 310 and a second board 320. However, the printed circuit board 300 may include at least three boards.
The first board 310 may be electrically connected to the display 100. The first board 310 may have various active elements, passive elements, and printed circuits constituting the driving circuit.
The first board 310 may have elements of relatively small sizes that mainly serve to transmit and receive signals related to the image or the video reproduced on the display 100. Accordingly, the first board 310 may have elements of relatively small volumes compared to the second board 320.
The second board 320 may be electrically connected to the first board 310 and disposed at a position spaced apart from the first board 310. Like the first board 310, the second board 320 may have various active elements, passive element, and printed circuits constituting the driving circuit.
For example, the second board 320 may be connected to an external power source to supply electricity to the first board 310 and the display 100. To this end, a circuit element 321 disposed on the second board 320 may have a relatively great volume for rectification conversion of voltage, and the like of the electricity supplied from external power source.
Therefore, the display module 10 needs to maintain a predefined separation distance between the first board 310 and the second board 320 such that the circuit element 321 disposed on the second board 320 is stably disposed without being in contact with the first board 310. In the display module 10, maintaining of the separation distance between the first board 310 and the second board 320 may be performed by a bracket 400 to be described later.
The printed circuit board 300 may further include a first connector 510 and a second connector 520. The first connector 510 may electrically connect the display 100 and the first board 310 to each other and may be constructed to be bendable.
The second connector 520 may electrically connect the first board 310 and the second board 320 to each other and may be constructed to be bendable. The first connector 510 and the second connector 520 may include a plurality of first connectors and a plurality of second connectors, respectively.
A portion of the driving circuit may be disposed on each of the first connector 510 and the second connector 520, and each of the first connector 510 and the second connector 520 may be made of a flexible material that is easy to be bent so as to be folded and unfolded well. The first connector 510 and the second connector 520 may be maintained in a bent form when mounted on the bracket 400.
The display module 10 according to an embodiment may further include the bracket 400. The bracket 400 may be coupled to the lower end of the display 100 and the printed circuit board 300 may be mounted on the bracket 400.
The printed circuit board 300 may be mounted on the bracket 400 and the bracket 400 may be coupled to the apron 200 to press the display 100.
As described above, in the display 100, the peeling of each layer may occur by the repetitive and continuous bending.
Further, because the display 100 and the apron 200 are also attached to each other, separation may occur between the display 100 and the apron 200 by the repetitive and continuous bending thereof. Like the peeling of the display 100 itself, the separation between the display 100 and the apron 200 is highly likely to occur at the lower end of the display 100. Such separation may cause the damage or the failure of the display module 10 and the display apparatus including the same.
The bracket 400 may be coupled to the display 100 and press the display 100 to maintain close contact between the display 100 and the apron 200, thereby effectively suppressing the separation between the apron 200 and the display 100.
Further, the bracket 400 may be coupled to the apron 200 and disposed to surround the lower end of the display 100, so that the lower end of the display 100 may be pressed by the bracket 400 from the front and pressed by the apron 200 from the rear.
The lower end of the display 100 may be pressed by the bracket 400 and the apron 200, so that, even when the display 100 is repeatedly bent, the layers constituting the display 100 may maintain close contact therebetween. Accordingly, the occurrence of peeling at the lower end of the display 100 may be effectively suppressed.
Hereinafter, with reference to the drawings, the bracket 400 will be described in more detail.
The bracket 400 according to an embodiment shown in
The bracket 400 may be coupled to a bottom face of the display 100, and may dispose the printed circuit board 300 on the bottom face of the display 100 in a way bent with respect to the display 100. The bracket 400 may allow the first board 310 and the second board 320 to maintain a distance from each other in the first direction.
Because of such structure, the bracket 400 may secure a space for preventing the first board 310 and the second board 320 from being in contact with each other or interfering with each other and for the elements disposed on each board to be mounted. Accordingly, the bracket 400 may stably mount the printed circuit board 300 including the driving circuit to the display module 10.
The bracket 400 may include a base 410 and a pressing coupling portion 420. The base 410 may be disposed on bottom faces of the display 100 and the apron 200 and directed in a direction intersecting the first direction of the display 100 and the apron 200, and the printed circuit board 300 may be mounted on the base 410.
The pressing coupling portion 420 may be bent from a front face of the base 410 in a way parallel to the first direction of the display 100, and may be coupled to the apron 200 and may be in contact with the display 100 to press the display 100.
The pressing coupling portion 420 may be disposed to be in contact with a front face of the display 100 at a lower portion of the display 100, and may press the lower portion of the display 100. In addition, the pressing coupling portion 420 may be disposed such that a length direction thereof is parallel to the second direction of the display 100 to press an entirety of a lower portion of the front face of the display 100.
The apron 200 may include a plurality of first protrusions 210 protruding from the lower end of the display 100. The first protrusion 210 may include a plurality of first protrusions, and the first protrusions 210 may be disposed to be spaced apart from each other along a length direction of the pressing coupling portion 420 of the bracket 400.
The pressing coupling portion 420 may be coupled to the first protrusion 210 to press the display 100. The pressing coupling portion 420 and the first protrusion 210 may be coupled to each other by a fastening mechanism such as a screw bolt.
The first protrusion 210 may have a first fastening hole 211 defined therein into which the coupling mechanism is fastened. The pressing coupling portion 420 may have a second fastening hole 421 defined therein into which the coupling mechanism is fastened at a position corresponding to the first fastening hole 211.
Because the first protrusion 210 protrudes in a downward direction from the lower end of the display 100, without any damage to the display 100, the coupling mechanism is fastened to the first fastening hole 211 and the second fastening hole 421, so that the bracket 400 may be coupled with the apron 200. Because of such structure, a lower portion of the apron 200 and the pressing coupling portion 420 of the bracket 400 may press lower portions of the front and rear faces of the display 100.
Because of such structure, the occurrence of the peeling of the display 100 at the lower end of the display 100 and the separation between the display 100 and the apron 200 may be effectively suppressed.
The base 410 may include a seating plate 411 and a second protrusion 412. The seating plate 411 may be bent from the pressing coupling portion 420 and the first board 310 may be seated on a top face of the seating plate 411. The second protrusion 412 may protrude downwardly of the seating plate 411, and may separate the first board 310 and the second board 320 from each other in the first direction.
The first board 310 and the second board 320 may be spaced apart from each other in the first direction of the display module 10 by the second protrusion 412. In such separation space defined by the second protrusion 412, the elements disposed on the first board 310 or the second board 320 having a predefined volume may be disposed without being in contact with each other.
The first board 310 may be seated on the top face of the seating plate 411, and the second board 320 may be seated on a bottom face of the first protrusion 210. In this regard, the first board 310 and the second board 320 may be coupled to the bracket 400 by the coupling mechanism such as the screw bolt, and may be disposed to be spaced apart from each other in the first direction of the display module 10.
The number of second protrusions 412 may be equal to or greater than 2. The number of second protrusions 412 and a position of each of the second protrusions 412 may be appropriately designed within a range capable of stably maintaining the spaced arrangement of the first board 310 and the second board 320.
In the bracket 400 according to an embodiment shown in
For example, the bracket 400 may be made of a metal material, and the second protrusion 412 may be formed as the seating plate 411 is deformed by the rolling processing. However, the present disclosure is not limited thereto.
In the bracket 400 according to an embodiment shown in
For example, the bracket 400 may be made of the plastic material and the second protrusion 412 may be formed by the injection molding. Because the structure other than the above is the same as that of the bracket 400 described above, duplicate description is omitted.
The apron 200 may be made of a flexible material that may be bent. However, the apron 200 may be formed to be relatively thick compared to the display 100 in order to stably support and protect the display 100. Therefore, as the plurality of recessed grooves 220 are defined in the apron 200, the apron 200 may be smoothly bent.
In the apron 200 according to an embodiment shown in
In the apron 200 according to an embodiment shown in
When the apron 200 has the curved recessed groove 220, the space defined by the recessed groove 220 is smaller than that of the aforementioned straight recessed groove 220. Because of such structure, the apron 200 having the curved recessed groove 220 may easily recover linearity again from the bent state.
Therefore, the apron 200 having the curved recessed groove 220 may smoothly deform the display 100 from the bent state to a straight unfolded state in a section where the display 100 is exposed to the outside.
Because the straight recessed groove 220 and the curved recessed groove 220 have the above-described characteristics, the shape of the recessed groove 220 of the apron 200 may be appropriately selected in consideration of operating characteristics required for the display module 10.
The display apparatus according to an embodiment may include a display module 10, a housing 20, a rolling guide 30, a guide 40, and a motor 50. The display module 10 is the same as described above.
