The display device DD can be installed inside the vehicle's AM to provide various information to the driver's DV (or user). The display device DD can provide the driver's DV with images such as weather images, speed images, map images, or movie images. The display device DD can be a touch screen that operates in response to touch input from the driver's DV.

[0070] According to embodiments of the present disclosure, the display device DD can expand and retract in a first direction DR1 according to the functional operation of the driver DV. For example, the display device DD may be a rollable display device. The rollable display device DD may include a housing (hereinafter, in... FIG. 4 and FIG. 5 (shown in the image) and a flexible display module that can be pulled into or out of the housing (hereinafter, in the image) FIG. 5 (As shown in the diagram). When the display device DD is extended in the first direction DR1, the image can be provided to the driver DV.

[0071] In the following text, the direction that intersects (or crosses) substantially perpendicularly with the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. Furthermore, as used herein, its meaning in a plan view is limited to observation on the third direction DR3.

[0072] As an example, a display device DD for vehicle AM ​​is shown, but embodiments of the present disclosure are not limited thereto. For example, the display device DD according to embodiments of the present disclosure can also be used in electronic devices such as smartphones, digital cameras, laptops, monitors, and smart TVs that provide images to users.

[0073] FIG. 3 It shows from FIG. 1 and FIG. 2 The image generated by the display device is provided to the user as a schematic diagram.

[0074] refer to FIG. 3 The display device DD can be expanded and unfolded into a flat surface. Users UR1 and UR2 can be arranged to face the display device DD. The surface facing users UR1 and UR2 of the display device DD can be the front surface of the display device DD. The front surface of the display device DD can be defined as the display surface of the display device DD.

[0075] Users UR1 and UR2 may include a first user UR1 and a second user UR2. The first user UR1 may be defined as the aforementioned driver DV. The second user UR2 may be defined as a passenger in the passenger seat. When facing the display device DD, the first user UR1 and the second user UR2 may be positioned on the left and right sides, respectively.

[0076] In the case of an extended display device DD, the display device DD can generate dual images. For example, the display device DD can generate a first image LIM and a second image RIM. When facing the front surface of the display device DD, the first image LIM can be provided on the left side relative to the display device DD, and the second image RIM can be provided on the right side relative to the display device DD.

[0077] A first image (LIM) can be provided to a first user (UR1). A second image (RIM) can be provided to a second user (UR2). For example, the first user (UR1) can use the first image (LIM) to access a map image for navigation. The second user (UR2) can use the second image (RIM) to watch a movie.

[0078] Therefore, the display device DD according to the embodiments of the present disclosure can generate dual images in the vehicle AM ​​and provide the dual images to a first user UR1 and a second user UR2, such as the driver DV and the passenger in the passenger seat.

[0079] FIG. 4 This is a schematic perspective view of a display device according to an embodiment of the present disclosure. FIG. 5 It is shown FIG. 4 The image shows the display device in extended mode. FIG. 6 It is shown FIG. 5 The image shows the rear of the display device in extended mode.

[0080] refer to FIG. 4 and FIG. 5 The display device DD may include a housing HS, a top rod HDB, a display module DM, and one or more function buttons FB.

[0081] The opening OP in the first direction DR1 can be defined within the housing HS. The housing HS can extend longer in the second direction DR2 than in the first direction DR1. Furthermore, the housing HS can extend longer in the first direction DR1 than in the third direction DR3. However, the embodiments are not limited thereto, and various modifications can be made to the shape of the display device DD within the spirit and scope of this disclosure.

[0082] The push rod HDB can be positioned in the opening OP. The push rod HDB can move away from or toward the housing HS in the first direction DR1.

[0083] The display module DM can be a flexible display module. When rolled up or unfolded similarly to a scroll, the display module DM can be pulled into or out of the housing HS. For example, as... FIG. 4 As shown, the display module DM can be rolled up and disposed inside the housing HS. Furthermore, as... FIG. 5 As shown, the display module DM can be unwound and disposed outside the housing HS.

[0084] The display module DM can be connected to the push rod HDB on the side opposite to the first direction DR1. The display module DM can be moved in the first direction DR1 using the push rod HDB.

[0085] When the push rod HDB moves away from the housing HS in the first direction DR1, such as FIG. 5 As shown, the display module DM can be pulled out of the housing HS through the opening OP. Therefore, the display module DM can be extended outside the housing HS and exposed to the outside of the housing HS. This operation can be defined as an extended mode. The front surface FS of the display module DM can be exposed to the outside, and the image can be provided to the aforementioned users UR1 and UR2.

[0086] Conversely, if the push rod HDB moves toward the housing HS in the first direction DR1, then as FIG. 4 As shown, the display module DM can be pulled into the housing HS through the opening OP. Therefore, the display module DM can be housed inside the housing HS and is not exposed to the outside. This operation can be defined as a retracted mode.

[0087] Function buttons FB can be located on the upper surface of the housing HS. Function buttons FB can provide various functions to the display device DD. For example, by using function buttons FB, the display module DM located inside the housing HS can be moved out of the housing HS, or the display module DM located outside the housing HS can be moved into the housing HS. By using function buttons FB, the brightness, sharpness, etc., of the image displayed from the display module DM can be controlled.

[0088] refer to FIG. 6 The lifting section ELP can be disposed on the rear surface BS of the display module DM. The rear surface BS of the display module DM can be defined as the surface opposite to the front surface FS. The lifting section ELP can have a foldable structure such as a bellows. The lifting section ELP can expand and contract in the first direction DR1.

[0089] The lifting section ELP can be connected to the top rod HDB and the housing HS on the rear surface BS of the display module DM. When the lifting section ELP is retracted, it can be located inside the housing HS, and when the lifting section ELP is extended, it can extend outside the housing HS.

[0090] According to the contraction and expansion of the lifting section ELP, the top rod HDB can move in the first direction DR1, and the display module DM can be pulled into or out of the housing HS. The lifting section ELP can be used to support the display module DM when it is expanded to a flat position.

The display module DM may have a rectangular shape having a long side extending in the first direction DR1 and a short side extending in the second direction DR2. However, embodiments of this disclosure are not limited thereto, and the display module DM may have various shapes such as circular or polygonal shapes.

[0093] The front surface FS of the aforementioned display module DM can be defined as the display surface DS, and has a plane defined by a first direction DR1 and a second direction DR2. The image IM generated from the display module DM can be provided to the user through the display surface DS.

[0094] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. An image may be displayed in the display area DA, and no image may be displayed in the non-display area NDA. The non-display area NDA may be adjacent to or surround the display area DA, and defines the edges of the display module DM printed with color (e.g., in a predetermined or selectable color).

[0095] The display module DM can be rolled up in the first direction DR1. The display module DM can be rolled up so that the display surface DS faces outward.

[0096] The side of the display module DM opposite to the side connected to the top rod HDB can be connected to the roller ROL. The other side of the display module DM can be connected to the stepped portion ST of the roller ROL, which is formed as a stepped section. The roller ROL can be housed inside the housing HS. The roller ROL can rotate clockwise and counterclockwise relative to the rotation axis RX extending in the second direction DR2.

[0097] Depending on the rotation of the roller ROL, the display module DM can be wound onto or unwound from the roller ROL. For example, when the roller ROL rotates counterclockwise, the display module DM can be wound onto the roller ROL. When the roller ROL rotates clockwise, the display module DM can be unwound from the roller ROL.

[0098] FIG. 9 yes FIG. 7 A schematic diagram of the cross-section of the display module in the image.

[0099] As an example, FIG. 9 A cross-section of the display module DM as viewed in the first direction DR1 is shown.

[0100] refer to FIG. 9 The display module DM may include an electronic panel EP, an optical layer OPL, and / or a window WIN. The optical layer OPL may be disposed on the electronic panel EP, and the window WIN may be disposed on the optical layer OPL.

[0101] The electronic panel (EP) can generate a first image (LIM) and a second image (RIM), sense external input, and reduce reflectivity to external light. Detailed configuration of the electronic panel (EP) will be referenced below. FIG. 10 Detailed description.

[0102] The optical layer OPL can refract a first image LIM and a second image RIM generated from the electronic panel EP, and provide the refracted first image LIM and second image RIM to a first user UR1 and a second user UR2, respectively. The first image LIM can be refracted at the optical layer OPL and provided to the first user UR1. The second image RIM can be refracted at the optical layer OPL and provided to the second user UR2. The optical layer OPL can be used to support the electronic panel EP. A more detailed configuration of the optical layer OPL will be referenced below. FIG. 13 Detailed description of the sectional view.

[0103] The window (WIN) can be installed on the optical layer (OPL). The window protects the OPL and the electronic panel (EP) from external scratches and impacts. The window can include, for example, glass or transparent plastic materials.

[0104] The first adhesive layer ADL1 can be disposed between the electronic panel EP and the optical layer OPL. The electronic panel EP and the optical layer OPL can be bonded to each other through the first adhesive layer ADL1. The second adhesive layer ADL2 can be disposed between the optical layer OPL and the window WIN. The optical layer OPL and the window WIN can be bonded to each other through the second adhesive layer ADL2.

[0105] The first adhesive layer ADL1 and the second adhesive layer ADL2 may include, for example, optically transparent adhesive (OCA) or pressure-sensitive adhesive (PSA).

[0106] FIG. 10 It is shown FIG. 9 A schematic cross-sectional view of the electronic panel configuration.

[0107] As an example, FIG. 10 A cross section of the electronic panel EP as viewed in the first direction DR1 is shown.

[0108] refer to FIG. 10 The electronic panel EP may include a display panel DP, an input sensing unit (or input sensing portion) ISP disposed on the display panel DP, and / or an anti-reflective layer RPL disposed on the input sensing unit ISP. The display panel DP may be a flexible display panel. For example, the display panel DP may include a flexible substrate and multiple elements disposed on the flexible substrate.

[0109] The display panel DP according to embodiments of this disclosure can be an emitting display panel, but is not particularly limited. For example, the display panel DP can be an organic light-emitting display panel or an inorganic light-emitting display panel. The light-emitting layer of an organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of an inorganic light-emitting display panel may include quantum dots, quantum rods, etc. Hereinafter, the display panel DP will be described as an organic light-emitting display panel.

[0110] An input sensing unit (ISP) may include one or more sensor units (or sensors) (not shown) for sensing external inputs. As an example, the ISP may sense external inputs using a capacitive method, but the sensing method of the ISP is not limited to this. When manufacturing an electronic panel (EP), the ISP may be directly formed on the display panel (DP).

[0111] An anti-reflective layer (RPL) can be applied to the input sensing unit (ISP). When manufacturing the electronic panel (EP), the RPL can be formed directly on the ISP. The RPL can be defined as a film used to prevent the reflection of external light. The RPL reduces the reflectivity of external light incident on the display panel (DP) from above the display device (DD).

[0112] If external light traveling towards the display panel DP is reflected from the display panel DP and returned to the external user (similar to a mirror), the user can visually perceive the external light. To prevent this phenomenon, as an example, the anti-reflective layer RPL may include one or more color filters that display the same color as the pixels of the display panel DP.

[0113] A color filter can filter external light into the same color as a pixel. In this case, the external light may not be visually perceptible to the user. However, embodiments of this disclosure are not limited to this, and the anti-reflective layer RPL may include a retarder and / or a polarizer to reduce reflectivity to external light.

[0114] As an example, the input sensing unit ISP can be directly formed on the display panel DP, and the anti-reflective layer RPL can be directly formed on the input sensing unit ISP, but the embodiments of this disclosure are not limited thereto. For example, the input sensing unit ISP can be manufactured separately and attached to the display panel DP via an adhesive layer, and the anti-reflective layer RPL can be manufactured separately and attached to the input sensing unit ISP via an adhesive layer.

[0115] FIG. 11 It is shown FIG. 10 A schematic cross-sectional view of the display panel configuration.

[0119] Pixels can be disposed in the display area DA. Each pixel may include a light-emitting element disposed in the display element layer DP-OLED and connected to a transistor disposed in the circuit element layer DP-CL.

[0120] The thin-film encapsulation layer (TFE) can be disposed on the circuit element layer (DP-CL) and cover the display element layer (DP-OLED) (or overlap with the display element layer (DP-OLED)). The thin-film encapsulation layer (TFE) may include an inorganic layer and an organic layer between the inorganic layers. The inorganic layer can protect the pixels from moisture / oxygen. The organic layer can protect the pixels from foreign matter such as dust particles.

FIG. 15 yes FIG. 13 An exploded stereoscopic view of the h-th and (h+1)-th joint units that are adjacent to each other in the joint unit.

[0137] FIG. 13 The diagram is generally used to describe the detailed configuration of the optical layer OPL, and for ease of description, the electronic panel EP is schematically shown as including only the pixels PX.

[0138] refer to FIG. 13 , FIG. 14 and FIG. 15 The pixel PX of the electronic panel EP may include a first pixel PX1 and a second pixel PX2. The first pixel PX1 and the second pixel PX2 may be included in the aforementioned display panel DP. The first pixel PX1 and the second pixel PX2 may be alternately arranged in the first direction DR1.

[0139] The optical layer OPL and the window WIN can be sequentially disposed on the electronic panel EP. The first adhesive layer ADL1 and the second adhesive layer ADL2 can be disposed between the electronic panel EP and the optical layer OPL, and between the optical layer OPL and the window WIN, respectively.

[0140] The optical layer OPL may include a lens LN, a resin layer RIN, and / or a bonding unit (or bonding portion) JU. The lens LN may be disposed on the electronic panel EP. The resin layer RIN may be disposed below the lens LN, between the lens LN and the electronic panel EP. The bonding unit JU may be disposed on the lens LN, between the window WIN and the electronic panel EP.

[0141] Lens LN can be arranged in a first direction DR1 and extend in a second direction DR2. When viewed in the second direction DR2, each lens LN can have an inverted triangular shape. In an embodiment, lens LN may comprise a transparent metal. For example, lens LN may comprise aluminum oxynitride.

[0142] The Knoop hardness of lens LN can be approximately 1500 kg / mm. 2 Approximately 2500 kg / mm 2 Lens LN can be harder than resin layer RIN. Lens LN can have a larger elastic modulus than resin layer RIN.

[0143] The grooves GV can be defined in the resin layer RIN to face the lens LN. The lens LN can be disposed in the grooves GV. The surface of the resin layer RIN defining the grooves GV can be defined as a recessed surface.

[0144] Although not shown, an adhesive layer may be disposed between the lens LN and the recessed surface of the defining groove GV of the resin layer RIN, and the lens LN may be attached to the resin layer RIN via the adhesive layer. The adhesive layer may include an optically transparent adhesive or a pressure-sensitive adhesive.

[0145] The resin layer RIN can be flexible. For example, the resin layer RIN can comprise silicone resin. Similar to a lens LN, the resin layer RIN can be disposed in a first direction DR1 and extend in a second direction DR2. The two side surfaces of each lens LN facing each other in the first direction DR1 can each have an inclined surface relative to a third direction DR3. The distance between the two side surfaces of each lens LN can gradually decrease in the downward direction.

[0146] The first adhesive layer ADL1 can be disposed between the electronic panel EP and the resin layer RIN. The electronic panel EP and the resin layer RIN can be bonded to each other through the first adhesive layer ADL1.

[0147] Similar to a lens LN, the bonding unit JU can be arranged in a first direction DR1 and extend in a second direction DR2. In an embodiment, the bonding unit JU may comprise fiber-reinforced plastic made of a transparent material.

[0148] The joining units JU can be disposed on the lens LN and rotatably connected to each other. For example, one side of the h-th joining unit JU_h and one side of the (h+1)-th joining unit JU_h+1 can be adjacent to each other and connected to each other to rotate relative to the rotation axis RX' parallel to the second direction DR2. h is a natural number greater than 0.

[0149] One side of the h-th joining unit JU_h and one side of the (h+1)-th joining unit JU_h+1, which are rotatably connected to each other, can be defined as a rotatable joining portion RCP. Each of the rotatable joining portions RCP can be disposed between two adjacent lenses LN (e.g., the h-th lens and the (h+1)-th lens). The lower portion of each of the rotatable joining portions RCP can have a downwardly convex curved surface.

[0150] The optical layer OPL may also include a light-blocking layer LSL. The light-blocking layer LSL may be disposed below the lower portion of the rotary coupling portion RCP. The light-blocking layer LSL may be disposed between lenses LN. The curved surface of the lower portion of the rotary coupling portion RCP may be coated with the light-blocking layer LSL. The light-blocking layer LSL may be black in color and block light.

[0151] Lens LN can be attached to bonding unit JU. For example, adhesive layer ADL can be disposed between lens LN and bonding unit JU, and lens LN can be attached to bonding unit JU through adhesive layer ADL. Adhesive layer ADL may include optically transparent adhesive or pressure-sensitive adhesive.

[0152] Each of the bonding units JU may include a flat portion PP adjacent to one side of each of the bonding units JU. The lens LN may be attached to the flat portion PP respectively.

[0153] The h-th lens LN can be set FIG. 15 The (h+1)th lens LN is located below the flat portion PP of the (h+1)th bonding unit JU_h+1 and attached to the flat portion PP of the (h+1)th bonding unit JU_h+1.

[0154] The window WIN can be disposed on the joining unit JU, and the second adhesive layer ADL2 can be disposed between the window WIN and the joining unit JU. The window WIN and the joining unit JU can be bonded to each other through the second adhesive layer ADL2.

[0155] The refractive index of lens LN can be greater than that of resin layer RIN. The refractive index of window WIN can be less than that of lens LN. For example, the refractive index of resin layer RIN can be about 1.44, the refractive index of lens LN can be about 1.64, and the refractive index of window WIN can be about 1.5. The refractive index of window WIN can be less than the refractive index of each of the second adhesive layer ADL2, bonding unit JU, and adhesive layer ADL.

[0156] The thickness TH of each of the lenses LNs relative to the third direction DR3 can be from about 45 μm to about 55 μm. The width WT of the upper surface of each of the lenses LNs relative to the first direction DR1 can be from about 60 μm to about 70 μm. The angle θ defined by the first side S1 and the second side S2 of each of the downward-oriented lenses LNs can be from about 70 degrees to about 90 degrees.

[0157] The distance DT between two adjacent lenses LN relative to the first direction DR1 can be approximately 30 μm to approximately 40 μm. The distance between the central portions of two adjacent lenses LN relative to the first direction DR1 can be defined as the pitch PT, and the pitch PT can be approximately 90 μm to approximately 110 μm.

[0158] A pair of adjacent first pixels PX1 and second pixels PX2 can be configured such that, in a planar view, the first pixels PX1 and the second pixels PX2 are positioned on either side of the corresponding lens LN relative to the central portion of the lens LN. Specifically, in the pair of first pixels PX1 and second pixels PX2, the first pixel PX1 can be positioned below the first side S1 of the corresponding lens LN, and the second pixel PX2 can be positioned below the second side S2 of the corresponding lens LN.

[0159] The first pixel PX1 can generate a first light L1, and the second pixel PX2 can generate a second light L2. The first light L1 and the second light L2 can be defined as light traveling toward the resin layer RIN.

[0160] The first light beam L1 can pass through the resin layer RIN towards the lens LN. Since the lens LN can have a larger refractive index than the resin layer RIN, the first light beam L1 can be refracted to the right at the first side S1. Since the window WIN can have a relatively small refractive index, the first light beam L1 can also be refracted to the right at the lower surface of the window WIN. A portion of the light generated from the first pixel PX1 can travel to the left and can be blocked at the light-blocking layer LSL.

[0161] Therefore, the light generated from the first pixel PX1 can be provided to the right side relative to the display module DM, but not to the left side relative to the display module DM. The first light L1 can substantially display the aforementioned first image LIM.

[0162] The second light beam L2 can pass through the resin layer RIN towards the lens LN. Since the lens LN can have a larger refractive index than the resin layer RIN, the second light beam L2 can be refracted to the left at the second side S2. Since the window WIN can have a relatively small refractive index, the second light beam L2 can also be refracted to the left at the lower surface of the window WIN. A portion of the light generated from the second pixel PX2 can travel to the right and can be blocked at the light-blocking layer LSL.

[0163] Therefore, the light generated from the second pixel PX2 can be provided to the left side relative to the display module DM, but not to the right side relative to the display module DM. The second light L2 can display the aforementioned second image RIM.

[0164] like FIG. 13 As shown, light generated from the first pixel PX1 can be further refracted to the right, thereby... FIG. 3 The second image RIM is provided to the second user UR2. For example... FIG. 13 As shown, light generated from the second pixel PX2 can be further refracted to the left, thereby... FIG. 3 The first image LIM in the image is provided to the first user UR1.

[0166] refer to FIG. 13 and FIG. 16 In the joint unit JU, they rotate relative to each other and as FIG. 16 In the case shown with a curved arrangement, the display module DM can be bent. In this situation, the display module DM can be as follows: FIG. 8 The image shows the winding on the roller ROL.

[0167] In the joint unit JU FIG. 13 When rotated and arranged flat as shown, the display module DM can be laid flat. In this case, the display module DM can be unwound from the roller ROL. Therefore, depending on the rotation of the coupling unit JU, the electronic panel EP can be wound and unwound.

[0168] As described above, the lens LN, which includes transparent metal, can have a relatively rigid structure. The lens LN can be used to flatly support a display module DM laid out as a flat surface. Furthermore, the lens LN can be used to flatly support an electronic panel EP laid out as a flat surface.

[0169] According to the above configuration, in the embodiments of this disclosure, when the rollable electronic panel EP is unwound, the lens LN can support the electronic panel EP flatly, and the image generated from the electronic panel EP can be provided to the users UR1 and UR2 in a dual manner.

The grooves GV' of the resin layer RIN can each have a concave shape corresponding to the shape of each of the lenses LN-1. The other components of the optical layer OPL-1 can be substantially the same as or similar to those components of the optical layer OPL. Depending on the rotation of the bonding unit JU, the display module DM can be wound and unwound, and the first light L1 and the second light L2 can be substantially as follows: FIG. 13 The image shown is refracted.

[0177] refer to FIG. 19A and FIG. 20The light generated from the first pixel PX1 can be mostly refracted to the right by the lens LN, and therefore the brightness of the first light L1 traveling to the right from the display module DM can be high. Thus, the first light L1 can be provided to be brighter relative to the right side of the display module DM. As a result, the first light L1 can be provided to a user positioned on the right side relative to the display module DM.

[0178] refer to FIG. 19B and FIG. 20 The light generated from the second pixel PX2 can be mostly refracted to the left by the lens LN, and therefore the brightness of the second light L2 traveling from the display module DM toward the left can be high. Thus, the second light L2 can be provided to make it brighter relative to the display module DM toward the left. As a result, the second light L2 can be provided to a user positioned on the left side relative to the display module DM.

The light generated from the second pixel PX2 can be mostly refracted to the left by the lens LN-1, and therefore the brightness of the second light L2 traveling to the left from the display module DM can be high.

[0182] Therefore, when lens LN-1 is used in the same manner as lens LN, the first light L1 and the second light L2 can be provided to users who are arranged on the right and left sides relative to the display module DM, respectively.
