Description

Display modules and electronic devices

[0001] The present disclosure relates to a display module and an electronic device, and more particularly, to a display module and an electronic device capable of providing an image using a plurality of display panels coupled to each other.

[0002] Recently, technological advancements in large-scale display devices have continued. In particular, technology related to multi-tiling displays, which combine multiple display panels to create a large display panel, has been attracting attention.

[0003] However, when implementing a large display panel by combining multiple display panels, there is a problem that the visibility of the image is reduced due to the gap caused by the bezel between the multiple display panels, i.e., the seam.

[0004] Accordingly, conventional technologies have attempted to solve the problem by minimizing the size of the bezel of the display panel or correcting the seam by placing an magnifying optical system on the display panel, but it is still pointed out that it is difficult to provide a high-resolution image while increasing the size of the display panel.

[0005] The present disclosure is intended to overcome the limitations of the prior art as described above, and to provide a display module and electronic device capable of effectively reducing the degradation of visibility caused by the bezel of each of a plurality of display panels.

[0032] The present embodiments may be modified and have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the scope to specific embodiments, but should be understood to encompass various modifications, equivalents, and / or alternatives of the embodiments of the present disclosure. In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0033] In describing the present disclosure, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present disclosure, a detailed description thereof will be omitted.

[0034] Additionally, the following embodiments may be modified in various other forms, and the scope of the technical concepts of the present disclosure is not limited to the following embodiments. Rather, these embodiments are provided to further faithfully and completely convey the technical concepts of the present disclosure to those skilled in the art.

[0035] The terminology used in this disclosure is for the purpose of describing specific embodiments only and is not intended to limit the scope of the rights. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0036] In this disclosure, expressions such as “has,” “can have,” “includes,” or “may include” indicate the presence of a corresponding feature (e.g., a component such as a number, function, operation, or part), and do not exclude the presence of additional features.

[0037] In this disclosure, expressions such as “A or B,” “at least one of A and / or B,” or “one or more of A or / and B” can include all possible combinations of the listed items. For example, “A or B,” “at least one of A and B,” or “at least one of A or B” can all refer to (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

[0038] The expressions “first,” “second,” “first,” or “second,” etc., used in this disclosure can describe various components, regardless of order and / or importance, and are only used to distinguish one component from another, but do not limit the components.

[0039] When it is said that a component (e.g., a first component) is “(operatively or communicatively) coupled with / to” or “connected to” another component (e.g., a second component), it should be understood that said component may be directly coupled to said other component, or may be coupled via another component (e.g., a third component).

[0040] On the other hand, when it is said that a component (e.g., a first component) is "directly connected" or "directly connected" to another component (e.g., a second component), it can be understood that no other component (e.g., a third component) exists between said component and said other component.

[0041] The expression "configured to" as used in the present disclosure may be used interchangeably with, for example, "suitable for," "having the capacity to," "designed to," "adapted to," "made to," or "capable of." The term "configured to" may not necessarily mean only "specifically designed to" in terms of hardware.

[0042] Instead, in some contexts, the phrase "a device configured to" may mean that the device, in conjunction with other devices or components, is "capable of" performing A, B, and C. For example, the phrase "a processor configured (or set) to perform A, B, and C" may refer to a dedicated processor (e.g., an embedded processor) for performing those operations, or a general-purpose processor (e.g., a CPU or application processor) that can perform those operations by executing one or more software programs stored in a memory device.

[0043] In the embodiments, a 'module' or 'part' performs at least one function or operation, and may be implemented as hardware or software, or as a combination of hardware and software. Furthermore, a plurality of 'modules' or 'parts' may be integrated into at least one module and implemented as at least one processor, except for a 'module' or 'part' that needs to be implemented as a specific hardware.

[0044] Meanwhile, the various elements and areas in the drawings are schematically drawn. Therefore, the technical concept of the present invention is not limited by the relative sizes or spacing depicted in the attached drawings.

[0045] Hereinafter, with reference to the attached drawings, embodiments according to the present disclosure will be described in detail so that a person having ordinary knowledge in the technical field to which the present disclosure pertains can easily implement the present disclosure.

[0046] FIG. 1 is a schematic diagram illustrating the configuration of a display module (100) according to one or more embodiments of the present disclosure. FIG. 2 is a diagram for explaining in detail a plurality of display panels (110). And FIG. 3 is a diagram for explaining in detail a plurality of magnifying optical systems (120).

[0047] Hereinafter, the present invention will be described with reference to FIGS. 1 to 3. However, FIGS. 1 to 3 only briefly illustrate the configuration of the display module (100) according to the present disclosure, and a more detailed configuration is illustrated in FIGS. 4 to 6.

[0048] The term 'display module (100)' refers to a configuration capable of displaying an image. Hereinafter, the term 'display panel (110)' is used as a term to refer to a configuration among the entire configurations constituting the display module (100) in which an actual image is displayed, and the term 'display module (100)' is used as a term to refer to a configuration including a panel driver (130) that drives the display panel (110) together with the display panel (110).

[0049] As illustrated in FIG. 1, the display module (100) may include a plurality of display panels (110) and a plurality of magnifying optical systems (120). Specifically, the plurality of display panels (110) may include n (where n is a natural number) display panels (110) including a first display panel (110-1) and a second display panel (110-2), and the plurality of magnifying optical systems (120) may include n (where n is a natural number) magnifying optical systems (120) including a first magnifying optical system (120-1) and a second magnifying optical system (120-2).

[0050] Hereinafter, a plurality of display panels and a plurality of magnifying optical systems are designated by reference numbers 110 and 120, respectively, and the first display panel, the second display panel, the first magnifying optical system, and the second magnifying optical system are designated by reference numbers 110-1, 110-2, 120-1, and 120-2, respectively.

[0051] Hereinafter, the two display panels (110) (i.e., the first display panel (110-1) and the second display panel (110-2)) and the two magnifying optical systems (120) (i.e., the first magnifying optical system (120-1) and the second magnifying optical system (120-2)) will be described in detail, but this is only for convenience of explanation. That is, the description of the two display panels (110) and the two magnifying optical systems (120) described below can also be extended to other display panels (110) and other magnifying optical systems (120) included in the display module (100).

[0052] Each of the plurality of display panels (110) may include a screen and a bezel. Here, the 'screen' refers to a configuration that displays an image, and the 'bezel' refers to a configuration that surrounds the border of the screen to increase the stability and protect each of the display panels (110).

[0053] Each screen of the plurality of display panels (110) can emit light corresponding to an image. Specifically, the first screen of the first display panel (110-1) and the second screen of the second display panel (110-2) can emit light corresponding to an image in the direction of the first magnifying optical system (120-1) and the second magnifying optical system (120-2).

[0054] The bezel of each of the plurality of display panels (110) may have a uniform thickness, but may also have different thicknesses depending on the location surrounding the screen. As illustrated in FIG. 2, the bezel of each of the plurality of display panels (110) may include a side bezel having a side thickness of a, an upper bezel having a thickness of b, and a lower bezel having a thickness of c. For example, the lower bezel may be thicker than the upper bezel due to a circuit for driving the display panel (110). FIG. 2 is a top-view illustration of a portion of the display module (100) illustrated in FIG. 1, that is, a portion corresponding to the first display panel (110-1) and the second display panel (110-2).

[0055] A plurality of display panels (110) correspond to each of a plurality of areas constituting the entire display panel (110), and can be combined (or connected) with each other to constitute the entire display panel (110). In addition, each of the plurality of display panels (110) can display a partial image corresponding to each of the plurality of areas constituting one image, thereby allowing the entire display panel (110) to display one image on a large scale. For example, the plurality of display panels (110) can be included in a device referred to as a multi-tiling display, a digital signage, a video wall, etc., but there is no particular limitation on the type of device that can include the plurality of display panels (110).

[0056] In one or more embodiments, a plurality of display panels (110) may be coupled to each other by overlapping portions of the bezels vertically to form an entire display panel (110). In particular, at least a portion of a first bezel (111-1) of a first display panel (110-1) may be disposed on at least a portion of a second bezel (111-2) of a second display panel (110-2), thereby forming a first step between the first display panel (110-1) and the second display panel (110-2). Here, the 'first bezel (111-1)' refers to a bezel of an area that overlaps vertically with the bezel of the second display panel (110-2) that is coupled to the first display panel (110-1) on the bezel of the first display panel (110-1), and the 'second bezel (111-2)' refers to a bezel of an area that overlaps vertically with the bezel of the first display panel (110-1) on the bezel of the second display panel (110-2).

[0057] As illustrated in FIG. 2, the first bezel (111-1) and the second bezel (111-2) may be the lower bezel of the first display panel (110-1) and the upper bezel of the second display panel (110-2), respectively. That is, as illustrated in FIG. 2, the upper bezel of the first display panel (110-1) may overlap the lower bezel of the second display panel (110-2).

[0058] In particular, in order to minimize the gap caused by the bezels of each of the plurality of display panels (110), it may be desirable to overlap the thick bezels so that they are placed below the thin bezels. As illustrated in FIG. 2, when the lower bezels of the plurality of display panels (110) are relatively thicker than the other bezels, the gap caused by the bezels of each of the first display panel (110-1) and the second display panel (110-2) can be minimized by overlapping the upper bezel of the first display panel (110-1) so that it is placed above the lower bezel of the second display panel (110-2). That is, as illustrated in FIG. 2, the first display panel (110-1) and the second display panel (110-2) can be overlapped so that the gap between the first screen of the first display panel (110-1) and the second screen of the second display panel (110-2) is as thick as the upper bezel of the first display panel (110-1).

[0059] Meanwhile, in FIG. 2, only a plurality of display panels (110) are shown being combined in the vertical direction, but it is of course possible for a plurality of display panels (110) to be combined in the left-right direction.

[0060] For example, the plurality of display panels (110) may further include a third display panel (110) connected to the first display panel (110-1) in the left-right direction and a fourth display panel (110) connected to the third display and the second display. In addition, the plurality of magnifying optical systems (120) may include a third magnifying optical system (120) disposed on the third display panel (110) and a fourth magnifying optical system (120) disposed on the fourth display panel (110). In addition, at least a portion of the third bezel of the third display panel (110) may be disposed on at least a portion of the fourth bezel of the fourth display panel (110), thereby forming a second step between the third display panel (110) and the fourth display panel (110). In addition, at least one of the third magnifying optical system (120) and the fourth magnifying optical system (120) may compensate for a decrease in visibility of the display panel (110) due to the second step.

[0061] Meanwhile, in FIG. 2, only the overlap between two display panels (110) is shown, but three or more display panels (110) may be arranged in the vertical direction in the same manner as shown in FIG. 2.

[0062] In particular, when the bezels of each of the plurality of display panels (110) are connected in parallel without overlapping each other vertically, in order to minimize the gap between the plurality of display panels (110), a method can be adopted in which the lower bezel, which is thicker than the other bezels, faces the outside and the upper bezels are connected so as to touch each other. However, this method has a limitation in that only two display panels (110) can be connected in only one of the vertical direction and the left-right direction, and thus only an arrangement of 2 x n (where n is a natural number) display panels (110) is possible. On the other hand, when the bezels of each of the plurality of display panels (110) are overlapped vertically in a method as illustrated in FIG. 2, three or more display panels (110) can be arranged in the vertical direction or the left-right direction, and thus an arrangement of n x n (where n is a natural number) display panels (110) is possible. That is, according to the present disclosure, free expansion is possible in terms of the size of the display module (100) and the aspect ratio (e.g., 4:3, 16:9, 21.9, etc.) of the display module (100).

[0063] When at least a portion of the first bezel (111-1) of the first display panel (110-1) is placed on at least a portion of the second bezel (111-2) of the second display panel (110-2), a first step may be formed between the first display panel (110-1) and the second display panel (110-2). The term 'first step' is used to specify the step formed between the first display panel (110-1) and the second display panel (110-2), and the first step may correspond to the height of the first display panel (110-1).

[0064] Although FIG. 1 illustrates that the entire first bezel (111-1) of the first display panel (110-1) is disposed on the entire second bezel (111-2) of the second display panel (110-2), this is merely exemplary. That is, a portion of the first bezel (111-1) may be disposed on a portion or the entire second bezel (111-2), and the entire first bezel (111-1) may be disposed on a portion or the entire second bezel (111-2).

[0065] The 'magnifying optical system (120)' refers to a configuration capable of magnifying an area where an image is displayed. In particular, the magnifying optical system (120) can magnify an area where an image is displayed on a display module (100) by changing the direction of light corresponding to the image in a preset direction, thereby compensating for a decrease in the visibility of the image.

[0066] According to the present disclosure, 'visibility degradation' refers to a phenomenon in which the 'bezel' and / or 'step' of the display panel (110) is visible along with the image while the display module (100) provides the image, and 'compensation for visibility degradation' refers to eliminating or minimizing the visibility degradation phenomenon of the display panel (110).

[0067] A plurality of magnifying optical systems (120) may correspond to each of a plurality of display panels (110). Hereinafter, embodiments in which a plurality of magnifying optical systems (120) are arranged on each of a plurality of display panels (110) will be described, but the entire plurality of magnifying optical systems (120) may be implemented as a single magnifying optical system (120).

[0068] The upper surfaces of the plurality of magnifying optical systems (120) can be connected in parallel without gaps. As illustrated in FIG. 1, the thicknesses of the plurality of magnifying optical systems (120) can be different from each other, but the upper surfaces of the plurality of magnifying optical systems (120) can be connected without gaps (i.e., seamlessly) to form a single plane.

[0069] The plurality of magnifying optical systems (120) may include one of a plurality of optical fibers, a lens array, and a waveguide. However, the present invention is not limited thereto, and any configuration capable of compensating for the deterioration of the visibility of the display panel (110) by magnifying the area where the image is displayed may be included in the plurality of magnifying optical systems (120) according to the present disclosure, regardless of its type.

[0070] An optical fiber is a fiber that can transmit light using light. The interior of an optical fiber may have a predetermined refractive index, which allows the direction of light transmitted along the interior of the optical fiber to be changed in a predetermined direction. An optical fiber may have the shape of a hexagonal column, but is not limited thereto.

[0071] In particular, in the present disclosure, a plurality of optical fibers may be vertically arranged on the screen of the display panel (110), as shown in FIG. 3, and may transmit light emitted from the screen to the upper surface of the magnifying optical system (120). Accordingly, an image may be displayed on the upper surface of the magnifying optical system (120). In particular, in order to improve the visibility of a bezel area (e.g., an upper area of ​​the first bezel (111-1)), the plurality of optical fibers may transmit light emitted through pixels close to the bezel to the bezel area at a constant rate to improve the visibility.

[0072] A lens array is an arrangement of multiple lenses. Each of the multiple lenses may have a convex or concave structure. A lens array includes multiple lenses, and the multiple lenses can change the direction of light emitted from the screen in a preset direction.

[0073] A waveguide is a structure that transmits light in a specific direction. Waveguides can have various shapes, such as circular, rectangular, or flat, and can change the direction of light emitted from a screen in a predetermined direction.

[0074] A plurality of magnifying optical systems (120) can change the direction of light emitted from the screens of each of the plurality of display panels (110) into a preset direction. Here, the 'preset direction' refers to a direction that can compensate for the decrease in visibility of the display panels (110), and in particular, may be a direction toward the upper part of the bezel overlapping between the plurality of display panels (110).

[0075] Specifically, the plurality of magnifying optical systems (120) may include a first magnifying optical system (120-1) disposed on a first display panel (110-1) and a second magnifying optical system (120-2) disposed on a second display panel (110-2). In addition, at least one of the first magnifying optical system (120-1) and the second magnifying optical system (120-2) may compensate for the deterioration of visibility of the plurality of display panels (110) due to the first step.

[0076] As illustrated in FIG. 3, the first bezel (111-1) of the first display panel (110-1) may be disposed on the second bezel (111-2) of the second display panel (110-2) to form a first step between the first display panel (110-1) and the second display panel (110-2). In this case, the optical fiber disposed on the first screen of the first display panel (110-1) may transmit light emitted from the first screen to an area corresponding to the first screen on the upper surface of the first magnifying optical system (120-1). In addition, the optical fiber disposed on the first bezel (111-1) of the first display panel (110-1) may change the direction of the light emitted from the first screen to transmit light emitted from the first screen to an area corresponding to the first bezel (111-1) on the upper surface of the first magnifying optical system (120-1).

[0077] Accordingly, the image displayed on the upper surface of the first magnifying optical system (120-1) and the second magnifying optical system (120-2) covers the upper portion of the first bezel (111-1) and the first step between the first display panel (110-1) and the second display panel (110-2). Therefore, the first magnifying optical system (120-1) can compensate for both the reduced visibility due to the first bezel (111-1) and the reduced visibility due to the first step.

[0078] According to the embodiments described above with reference to FIGS. 1 to 3, the display module (100) overlaps the bezels of each of the plurality of display panels (110) to reduce the width of the entire bezel, and also compensates for the reduction in visibility due to the bezel and the reduction in visibility due to the step caused by the overlapping of the bezels by using a plurality of magnifying optical systems (120).

[0079] Accordingly, when implementing a large display module (100) by combining multiple display panels (110), the visibility of the image can be significantly improved while minimizing the gap between the multiple display panels (110).

[0080] In addition, as described above, since three or more display panels (110) can be combined in the vertical direction or the left-right direction by overlapping the bezels of each of the plurality of display panels (110) in accordance with the present disclosure, there is an advantage in that the size of the entire display panel (110) can be expanded without limitation.

[0081] Hereinafter, various embodiments of the configuration of the display module (100) according to the present disclosure will be described with reference to FIGS. 4 to 8. In FIGS. 4 to 8, only three display panels (110) and three magnifying optical systems (120) are illustrated, and among them, two display panels (110) (i.e., the first display panel (110-1) and the second display panel (110-2)) and two magnifying optical systems (120) (i.e., the first magnifying optical system (120-1) and the second magnifying optical system (120-2)) will be described in detail. However, as mentioned above, this is only for convenience of explanation.

[0082] FIGS. 4 and 5 are drawings for explaining one or more embodiments related to a display module (100) in which a plurality of display panels (110) are arranged parallel to each other.

[0083] As described above, the bezels of each of the plurality of display panels (110) may overlap each other. In addition, as illustrated in FIGS. 4 and 5 , the plurality of display panels (110) may be arranged parallel to the upper surfaces of the plurality of magnifying optical systems (120), and thus, each of the plurality of display panels (110) may also be arranged parallel to each other.

[0084] When each of the plurality of display panels (110) is arranged parallel to the upper surface of the plurality of magnifying optical systems (120), the thicknesses of each of the plurality of magnifying optical systems (120) may be different from each other so that the upper surfaces of the plurality of magnifying optical systems (120) are connected in parallel to form a single plane. For example, as illustrated in FIGS. 4 and 5, the thickness (x2) of the second magnifying optical system (120-2) may be thicker than the thickness (x1) of the first magnifying optical system (120-1).

[0085] As illustrated in FIGS. 4 and 5, the display module (100) may further include a panel driver (130). The panel driver (130) may drive the display panel (110) and may be disposed below the display panel (110). In FIGS. 4 and 5, only a PBA (Polarizer-Backlight Assembly) including a cable line, a polarizer, and a backlight is illustrated, but the panel driver (130) may also include various types of circuits and chips. In addition, the display panel (110) is not limited to an LCD (liquid crystal display), and may include various displays having a bezel, such as an OLED (organic light emitting diode).

[0086] When each of the plurality of display panels (110) is arranged parallel to the upper surface of the plurality of magnifying optical systems (120), in order to make the lower surface of the panel driver (130) form a single plane, the thicknesses of the lower region of the first display panel (110-1) and the lower region of the second display panel (110-2) in the panel driver (130) may be different from each other. For example, as illustrated in FIGS. 4 and 5, the thickness (y1) of the region corresponding to the lower portion of the first display panel (110-1) in the panel driver (130) may be thicker than the thickness (y2) of the region corresponding to the lower portion of the second display panel (110-2).

[0087] As described above, at least one of the first magnifying optical system (120-1) and the second magnifying optical system (120-2) can compensate for the decrease in visibility of the plurality of display panels (110) due to the first step. The 'magnifying area' in FIGS. 4 and 5 represents an area where light emitted from the first screen is magnified to compensate for the decrease in visibility due to the first step.

[0088] As illustrated in FIG. 4, the second magnifying optical system (120-2) can compensate for the decrease in visibility due to the first step by changing the direction of light emitted from a portion of the second screen toward the direction of the first bezel (111-1). That is, in this case, the decrease in visibility due to the first step can be compensated for by the second magnifying optical system (120-2) rather than the first magnifying optical system (120-1).

[0089] As illustrated in FIG. 5, the first magnifying optical system (120-1) and the second magnifying optical system (120-2) can compensate for the decrease in visibility due to the first step by changing the direction of light emitted from a portion of the first screen and the direction of light emitted from a portion of the second screen, respectively, in the direction of the first bezel (111-1). That is, in this case, the decrease in visibility due to the first step can be compensated for by the first magnifying optical system (120-1) and the second magnifying optical system (120-2).

[0090] Meanwhile, in the case where the visibility degradation due to the first step is compensated for by one magnifying optical system (120) (i.e., the embodiment of FIG. 4), the size of the magnifying area becomes larger compared to the case where the visibility degradation due to the first step is compensated for by two magnifying optical systems (120) (i.e., the embodiment of FIG. 5). In addition, as the size of the magnifying area becomes larger, the thickness of the magnifying optical system (120) increases, and as a result, the weight of the magnifying optical system (120) and the deterioration of image quality due to the occurrence of white haze and the decrease in transmittance also increase.

[0091] Therefore, when the display module (100) is implemented to compensate for the decrease in visibility due to one step by two magnifying optical systems (120) as in the embodiment of FIG. 5, compared to the case where the display module (100) compensates for the decrease in visibility due to one step by one magnifying optical system (120) as in the embodiment of FIG. 4, problems such as an increase in the thickness of the magnifying optical system (120), an increase in the weight of the magnifying optical system (120), and the occurrence of white haze and a decrease in transmittance can be minimized.

[0092] FIG. 6 and FIG. 7 are drawings for explaining one or more embodiments related to a display module (100) in which each of a plurality of display modules (100) is arranged to be inclined.

[0093] As described above, the bezels of each of the plurality of display panels (110) may overlap each other. Furthermore, as illustrated in FIGS. 6 and 7 , the plurality of display panels (110) may be arranged at a preset angle relative to the upper surfaces of the plurality of magnifying optical systems (120).

[0094] When each of the plurality of display panels (110) is arranged to have a preset angle based on the upper surface of the plurality of magnifying optical systems (120), the thicknesses of each of the plurality of magnifying optical systems (120) do not need to be different from each other so that the upper surfaces of the plurality of magnifying optical systems (120) are connected in parallel to form a single plane.

[0095] That is, as illustrated in FIGS. 6 and 7, when the lower surfaces of the plurality of magnifying optical systems (120) are tilted at an angle equal to the angle at which the plurality of display panels (110) are tilted, the upper surfaces of the plurality of magnifying optical systems (120) can form a single plane even if the thicknesses of each of the plurality of magnifying optical systems (120) are not implemented differently as in the embodiments of FIGS. 4 and 5. In this case, the shapes of the first magnifying optical system (120-1) and the second magnifying optical system (120-2) can be identical to each other.

[0096] In addition, when each of the plurality of display panels (110) is arranged to have a preset angle based on the upper surface of the plurality of magnifying optical systems (120), in order to make the lower surface of the panel driving unit (130) form one plane, the thicknesses of the lower region of the first display panel (110-1) and the lower region of the second display panel (110-2) in the panel driving unit (130) do not need to be different from each other.

[0097] That is, as illustrated in FIGS. 6 and 7, when the areas corresponding to the plurality of display panels (110) on the upper surface of the panel driver (130) are tilted by the angle at which the plurality of display panels (110) are tilted, even if the thicknesses of the lower area of ​​the first display panel (110-1) and the lower area of ​​the second display panel (110-2) are not implemented differently in the panel driver (130) as in the embodiments of FIGS. 4 and 5, the lower surface of the panel driver (130) can form a single plane. In this case, the shapes of the lower area of ​​the first display panel (110-1) and the lower area of ​​the second display panel (110-2) can be the same.

[0098] As described above, at least one of the first magnifying optical system (120-1) and the second magnifying optical system (120-2) can compensate for the decrease in visibility of the plurality of display panels (110) due to the first step. The 'magnification area' of FIGS. 6 and 7, similarly to the cases of FIGS. 4 and 5, represents an area where light emitted from the first screen is magnified to compensate for the decrease in visibility due to the first step.

[0099] As illustrated in FIG. 6, the second magnifying optical system (120-2) can compensate for the decrease in visibility due to the first step by changing the direction of light emitted from a portion of the second screen toward the direction of the first bezel (111-1). That is, in this case, the decrease in visibility due to the first step can be compensated for by the second magnifying optical system (120-2) rather than the first magnifying optical system (120-1).

[0100] As illustrated in FIG. 7, the first magnifying optical system (120-1) and the second magnifying optical system (120-2) can compensate for the decrease in visibility due to the first step by changing the direction of light emitted from a portion of the first screen and the direction of light emitted from a portion of the second screen, respectively, in the direction of the first bezel (111-1). That is, in this case, the decrease in visibility due to the first step can be compensated for by the first magnifying optical system (120-1) and the second magnifying optical system (120-2).

[0101] When the display module (100) is implemented to compensate for the decrease in visibility due to one step by two magnifying optical systems (120) as in the embodiment of FIG. 7, compared to the case where the display module (100) compensates for the decrease in visibility due to one step by one magnifying optical system (120) as in the embodiment of FIG. 6, the problems of increased thickness of the magnifying optical system (120), increased weight of the magnifying optical system (120), and deterioration of image quality due to white haze occurrence and decreased transmittance can be minimized.

[0102] Meanwhile, as described above with reference to FIGS. 4 and 5, when each of the plurality of display panels (110) is arranged parallel to the upper surface of the plurality of magnifying optical systems (120), the thicknesses of the plurality of magnifying optical systems (120) may be different from each other. In this case, as the number of the plurality of display panels (110) and the number of the plurality of magnifying optical systems (120) corresponding thereto increase, the thickness of the magnifying optical system (120) must decrease. However, if the thickness of the magnifying optical system (120) decreases below a critical thickness, the magnifying optical system (120) cannot perform its normal function. Therefore, when each of the plurality of display panels (110) is arranged parallel to the upper surface of the plurality of magnifying optical systems (120), there is a limit to the number of the plurality of display panels (110), which may result in limitations in increasing the size of the display.

[0103] On the other hand, when each of the plurality of display panels (110) is arranged to have a preset angle with respect to the upper surface of the plurality of magnifying optical systems (120), as in the embodiments of FIGS. 6 and 7, the thicknesses of each of the plurality of magnifying optical systems (120) do not need to be different from each other. Therefore, when each of the plurality of display panels (110) is arranged to have a preset angle with respect to the upper surface of the plurality of magnifying optical systems (120), there is no limitation on the number of the plurality of display panels (110), and as a result, the display can be easily enlarged.

[0104] Meanwhile, as described above with reference to FIGS. 4 and 5, when each of the plurality of display panels (110) is arranged parallel to the upper surface of the plurality of magnifying optical systems (120), the thicknesses of the lower region of the first display panel (110-1) and the lower region of the second display panel (110-2) in the panel driver (130) may be different from each other. In this case, as the number of the plurality of display panels (110) and the number of the plurality of magnifying optical systems (120) corresponding thereto increase, the thickness of some regions of the panel driver (130) must decrease. However, if the thickness of the panel driver (130) decreases below a critical thickness, it may be difficult to arrange the configuration required for the panel driver (130). In addition, it may be difficult to design and manufacture panel drivers (130) having different thicknesses for each region.

[0105] On the other hand, when each of the plurality of display panels (110) is arranged to have a preset angle with respect to the upper surface of the plurality of magnifying optical systems (120), as in the embodiments of FIGS. 6 and 7, the thicknesses of the lower region of the first display panel (110-1) and the lower region of the second display panel (110-2) in the panel driver (130) do not need to be different from each other. Therefore, when each of the plurality of display panels (110) is arranged to have a preset angle with respect to the upper surface of the plurality of magnifying optical systems (120), there is no limitation on the number of the plurality of display panels (110), and the design and manufacturing of the panel driver (130) can be facilitated.

[0106] FIG. 8 is a drawing illustrating one or more embodiments related to a display module (100) further including a three-dimensional panel (140).

[0107] As illustrated in FIG. 8, the display module (100) according to the present disclosure may further include a three-dimensional panel (140) in addition to a plurality of display panels (110), a plurality of magnifying optical systems (120), and a panel driver (130). The three-dimensional panel (140) is disposed on the plurality of magnifying optical systems (120) and refers to a configuration for displaying an image in three dimensions. For example, the three-dimensional panel (140) may include a lenticular lens array and a parallax barrier.

[0108] A 'lenticular lens array' refers to a set of lenticular lenses that can provide a three-dimensional effect through an arrangement of a plurality of micro lenses, and may include not only a film-type lens array but also a liquid crystal lens that can switch and provide a two-dimensional image and a three-dimensional image according to an external voltage. In particular, the lenticular lens may have a convex lens shape as illustrated in FIG. 8, and may output light emitted through a plurality of display panels (110) and passing through a plurality of magnifying optical systems (120) in a preset direction. That is, light that passes through a plurality of magnifying optical systems (120) and is incident on the lenticular lens array may be refracted in a preset direction inside the lenticular lens or may pass through the inside of the lenticular lens and be emitted outside the lenticular lens.

[0109] Here, the 'pre-set direction' may be a direction for mapping the direction of each of the lights incident on the lenticular lens array through a plurality of pixels (111) and a plurality of magnifying optical systems (120) to one of a plurality of viewpoints for providing a three-dimensional image.

[0110] Meanwhile, a 'parallax barrier' refers to an optical element configured by alternately arranging slits that transmit and block light on the upper portion of a display panel (110). Each slit included in the parallax barrier transmits or blocks light emitted through multiple display panels (110) and passing through multiple magnifying optical systems (120), thereby providing different images at various viewpoints.

[0111] In addition to the lenticular lens array and parallax barrier described above, any configuration capable of providing a three-dimensional image based on incident light may correspond to the three-dimensional panel (140) according to the present disclosure, regardless of its type.

[0112] FIG. 9 is a block diagram briefly illustrating the configuration of an electronic device (1000) according to one or more embodiments of the present disclosure.

[0113] As illustrated in FIG. 9, an electronic device (1000) according to the present disclosure may include a display module (100), a memory (200), and a processor (300). However, the configurations illustrated in FIG. 9 are merely exemplary, and in implementing the present disclosure, new configurations such as a communication unit, an input unit, or an output unit may be added, or some configurations may be omitted, in addition to the configuration illustrated in FIG. 9.

[0114] The display module (100) refers to a configuration capable of displaying an image, and may have a structure according to various embodiments of FIGS. 1 to 8 in particular. Since the display module (100) has been described above with reference to FIGS. 1 to 8, a duplicate description of the same content will be omitted. That is, the various embodiments described above with reference to FIGS. 1 to 8 may also be applied to the display module (100) included in the electronic device (1000). Meanwhile, there are no special restrictions on the type of light source constituting the display module (100) and the design of the driving circuit.

[0115] The memory (200) may store at least one instruction related to the electronic device (1000). In addition, the memory (200) may store an O / S for driving the electronic device (1000). In addition, the memory (200) may store various software programs or applications for operating the electronic device (1000) according to various embodiments of the present disclosure. In addition, the memory (200) may include a semiconductor memory such as a flash memory or a magnetic storage medium such as a hard disk.

[0116] Specifically, the memory (200) may store various software modules for operating the electronic device (1000) according to various embodiments of the present disclosure, and the processor (300) may control the operation of the electronic device (1000) by executing the various software modules stored in the memory (200). That is, the memory (200) is accessed by the processor (300), and data reading / recording / modifying / deleting / updating, etc. may be performed by the processor (300).

[0117] Meanwhile, in the present disclosure, the term memory (200) may be used to mean a memory (200), a ROM, a RAM in a processor (300), or a memory card mounted in an electronic device (1000).

[0118] In one or more embodiments, the memory (200) may store image data and instructions for displaying an image on the display module (100) based on the image data. In addition, various information necessary within the scope of achieving the purpose of the present disclosure may be stored in the memory (200), and the information stored in the memory (200) may be updated as received from an external device or input by a user.

[0119] The processor (300) controls the overall operation of the electronic device (1000). Specifically, the processor (300) is connected to the configuration of the electronic device (1000) including the display module (100) and the memory (200), and can control the overall operation of the electronic device (1000) by executing at least one instruction stored in the memory (200) as described above. In particular, the processor (300) can control the display module (100) to display an image based on image data stored in the memory (200).

[0120] The processor (300) may be implemented in various ways. For example, the processor (300) may be implemented as at least one of an application-specific integrated circuit, an embedded processor, a microprocessor, hardware control logic, a hardware finite state machine, and a digital signal processor. Meanwhile, the term "processor (300)" in the present disclosure may be used to encompass a CPU, a GPU, an MPU, and the like.

[0121] Meanwhile, in the description of the present disclosure, the processor (300) and the panel driver (130) are described as separate components, but this is only for convenience of explanation. That is, the processor (300) may include at least a part of the panel driver (130), and the panel driver (130) may include at least a part of the processor (130).

[0122] In one or more embodiments, the processor (300) may correct image data stored in the memory (200) to compensate for image distortion or luminance distortion in an area where visibility degradation is compensated for by a plurality of magnifying optical systems (120). Then, the processor (300) may control the display module (100) to display an image based on the corrected image data.

[0123] Specifically, according to the embodiments of FIGS. 1 to 8, it is possible to compensate for the reduced visibility due to the bezel and the reduced visibility due to the step between the plurality of display panels (110) by using a plurality of magnifying optical systems (120), but image distortion or brightness distortion may occur in the area where the reduced visibility is compensated for by the plurality of magnifying optical systems (120).

[0124] For example, an area where light emitted from multiple screens is magnified by the magnifying optical system (120) (i.e., an enlarged area) may cause image distortion because a larger image is displayed by a single light emitted from the screen compared to other areas. In addition, brightness distortion may also occur depending on the thickness difference between the multiple magnifying optical systems (120).

[0125] Therefore, by correcting the image data to compensate for image distortion or luminance distortion as described above, image distortion or luminance distortion in an area where visibility degradation is compensated for by a plurality of magnifying optical systems (120) can be prevented or minimized.

[0126] Each of the components (e.g., modules or programs) according to the various embodiments of the present disclosure as described above may be composed of a single or multiple entities, and some of the sub-components described above may be omitted, or other sub-components may be further included in the various embodiments. Alternatively or additionally, some components (e.g., modules or programs) may be integrated into a single entity, which may perform the same or similar functions as those performed by each of the respective components prior to integration.

[0127] According to various embodiments, operations performed by a module, program or other component may be executed sequentially, in parallel, iteratively or heuristically, or at least some operations may be executed in a different order, omitted, or other operations may be added.

[0128] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
