[0052] Light emitted from the display device 1 may travel in a specific direction. For example, the light emitted from the display device 1 may travel toward the driver's seat (not shown). The light emitted from the display device 1 may travel toward the passenger seat (not shown). The light emitted from the display device 1 may not travel toward the windshield 1200. Alternatively, a relatively small proportion of the light emitted from the display device 1 may travel toward the windshield 1200. If the light emitted from the display device 1 travels toward the windshield 1200, it may be reflected by the windshield 1200 and reach the driver's seat. Therefore, the driver may only be able to see the image of the display device 1 formed on the windshield 1200, and may not be able to recognize objects ahead, which may pose a safety issue during driving. In this embodiment, the light emitted from the display device 1 disposed in the center fascia 1500 may travel in a specific direction.

For example, the needle and gauge of a tachometer and various warning light icons may be displayed using digital signals.

[0054] Light emitted from the display device 1 may travel in a specific direction. For example, the light emitted from the display device 1 may travel toward the driver's seat (not shown). The light emitted from the display device 1 may not travel toward the windshield 1200. Alternatively, a relatively small proportion of the light emitted from the display device 1 may travel toward the windshield 1200. If the light emitted from the display device 1 travels toward the windshield 1200, it may be reflected by the windshield 1200 and reach the driver's seat. Therefore, the driver may recognize the image of the display device 1 formed on the windshield 1200, which may pose a safety issue during driving. In this embodiment, the light emitted from the display device 1 disposed in the cluster 1400 may travel in a specific direction. Therefore, the light traveling toward the windshield 1200 may be minimized.

[0061] 4A to 4C are cross-sectional views each showing a schematic view of the display device 1 taken along line AA' of FIG.

[0062] 4A and 4B, the display device 1 may include a substrate 100, a display layer 200, an encapsulating member 300, and a light control polarizing film 500. The substrate 100 may be glass or may include a polymer resin such as polyethersulfone, polyarylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyimide, polycarbonate, cellulose triacetate, cellulose acetate propionate, etc. In one embodiment, the substrate 100 may have a multilayer structure including a base layer and a barrier layer (not shown) including the aforementioned polymer resin. The substrate 100 including the polymer resin may be flexible, rollable, and bendable.

[0063] The display layer 200 may be disposed on the substrate 100. The display layer 200 may include a pixel circuit layer and a light emitting element layer. The pixel circuit layer may include pixel circuits. The pixel circuits may include transistors and storage capacitors. The light emitting element layer may include light emitting elements connected to the pixel circuits.

[0064] Referring to FIG. 4A, the encapsulation member 300 may include an encapsulation layer 300L. The encapsulation layer 300L may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. The at least one inorganic encapsulation layer and the at least one organic encapsulation layer may be alternately stacked.

[0065] The at least one organic encapsulation layer may include a polymer-based material, such as an acrylic resin, an epoxy resin, a polyimide, or a polyethylene. In one embodiment, the at least one organic encapsulation layer may include an acrylate.

[0066] Referring to FIG. 4B , the encapsulation member 300 may include an encapsulation substrate 340 and a sealing member 350. The encapsulation substrate 340 may be disposed on the display layer 200. The encapsulation member 350 may be disposed between the substrate 100 and the encapsulation substrate 340 in the non-display area (NDA). The encapsulation substrate 340 may have a thickness similar to that of the substrate 100. For example, the thickness of the substrate 100 and the encapsulation substrate 340 may be approximately 0.3 mm. The internal space between the display layer 200 and the encapsulation substrate 340 may be sealed. The sealing member 350 may also be a sealant, and in other embodiments, the sealing member 350 may include a material that is cured by a laser. For example, the sealing member 350 may be a frit. Specifically, the sealing member 350 may include an organic sealant such as a urethane-based resin, an epoxy-based resin, or an acrylic-based resin, or an inorganic sealant. In one embodiment, the sealing member 350 may include silicone. The urethane-based resin may be, for example, urethane acrylate, etc. The acrylic-based resin may be, for example, butyl acrylate, ethylhexyl acrylate, etc. Meanwhile, the sealing member 350 may include a material that is hardened by heat.

[0067] 4C, the encapsulation member 300 may include an encapsulation substrate 340' and a sealing member 350. The encapsulation substrate 340' may have a thickness thinner than that of the substrate 100. For example, the encapsulation substrate 340' may have a thickness that is one-third that of the substrate 100. In some embodiments, the thickness of the encapsulation substrate 340' may be approximately 0.1 mm. The encapsulation substrate 340' may be formed by adjusting the thickness through a grinding process after the encapsulation substrate 340 of FIG. 4B is bonded to the substrate 100 by the sealing member 350.

[0068] 4A to 4C, a light control polarizing film 500 may be disposed on the encapsulating member 300. The light control polarizing film 500 may reduce the reflectance of light (e.g., external light) incident from the outside toward the display device 1 and may control the direction of light emitted from the display layer 200. For example, the second direction (e.g., y direction) component of the light emitted from the display layer 200 may be at least partially removed by the light control polarizing film 500.

[0069] The light control polarizing film 500 may include an adhesive layer 510 , a transparent layer 520 , a plurality of light-blocking lines 530 , and a polarizing film layer 550 .

[0070] The adhesive layer 510 may be disposed on the lower part of the light control polarizing film 500 and may serve to attach the light control polarizing film 500 to the sealing member 300. The adhesive layer 510 may also be a pressure sensitive adhesive (PSA).

[0071] The transparent layer 520 may be made of a resin having high light transmittance. For example, the transparent layer 520 may include a cellulose resin, a polyolefin resin, a polyester resin, polystyrene, polyurethane, polyvinyl chloride, an acrylic resin, or the like. The transparent layer 520 may include a plurality of grooves. The plurality of grooves may be arranged at regular intervals.

[0072] The plurality of light-blocking lines 530 may fill the plurality of grooves of the transparent layer 520, respectively. The plurality of light-blocking lines 530 may include a light-blocking material. For example, the plurality of light-blocking lines 530 may include a black material. The plurality of light-blocking lines 530 may be formed by filling the plurality of grooves with black ink and then irradiating them with ultraviolet light. The path of light emitted from the display layer 200 may be controlled depending on the arrangement of the plurality of light-blocking lines 530.

[0073] The polarizing film layer 550 may be disposed on the transparent layer 520 and the plurality of light-blocking lines 530. That is, the polarizing film layer 550 may be disposed farther from the display layer 200 than the plurality of light-blocking lines 530. The plurality of light-blocking lines 530 may be disposed closer to the display layer 200 than the polarizing film layer 550.

[0074] The polarizing film layer 550 may include a polarizing layer and a phase retardation layer. The phase retardation layer may be a film type or a liquid crystal coating type and may include a λ / 2 phase retarder (half-wave plate) and / or a λ / 4 phase retarder (quarter-wave plate). The polarizing layer may also be a film type or a liquid crystal coating type. The film type may include a stretched synthetic resin film, while the liquid crystal coating type may include liquid crystals aligned in a predetermined orientation. The polarizing film layer 550 may further include a protective layer disposed on and / or under the polarizing layer and the phase retardation layer. The polarizing film layer 550 may reduce the reflectance of light (e.g., external light) incident from the outside toward the display device 1.

[0075] In general, a transparent layer 520 and a plurality of light-blocking lines 530 may be formed on a base film made of polycarbonate or polyethylene terephthalate (PET) to form a plurality of light-blocking lines 530 that control the light path. Then, the base film on which the plurality of light-blocking lines 530 are formed and a polarizing film may be attached using a light-transparent adhesive layer and placed on an encapsulating member.

[0076] In this case, due to the characteristics of the base film having birefringence, when the base film is placed on top of the display layer 200, a double layer (ghost image) is formed, and the distance between the display layer 200 and the multiple light-shielding lines 530 becomes large due to the thickness of the base film and the optically transparent adhesive layer, so the double layer can be more clearly seen.

[0077] In this embodiment, a light control polarizing film 500 is provided in which a transparent layer 520 and a plurality of light-blocking lines 530 are directly formed under a polarizing film layer 550 so that the plurality of light-blocking lines 530 can be arranged adjacent to the display layer 200, without using a base film and a light-transparent adhesive layer such as those made of polycarbonate or polyethylene terephthalate (PET).

[0078] 5 is a cross-sectional view schematically illustrating a light control polarizing film 500 according to one embodiment of the present invention. In FIG. 5, the same reference numerals as in FIGS. 4A to 4C denote the same components.

[0079] 5, the light control polarizing film 500 includes an adhesive layer 510, a transparent layer 520, a plurality of light-shielding lines 530, and a polarizing film layer 550. A protective film 560 may be further disposed on the polarizing film layer 550.

[0080] In the light control polarizing film 500, a transparent layer 520 having a plurality of light-blocking lines 530 arranged thereon may be directly disposed on a polarizing film layer 550 having a polarizing layer 552. The plurality of light-blocking lines 530 may be arranged so as to fill the plurality of grooves in the transparent layer 520, respectively.

[0081] The polarizing film layer 550 may include a first protective layer 551 , a phase retardation layer 553 , a polarizing layer 552 , a second protective layer 554 , and a hard coating layer 555 .

[0082] The polarizing layer 552 polarizes light incident from a light source (not shown) in the same direction as the polarization axis. In some embodiments, the polarizing layer 552 includes a polarizer and / or a dichroic dye in a polyvinyl alcohol (PVA) film. The dichroic dye may be iodine molecules and / or dye molecules.

[0083] In some embodiments, the polarizing layer 552 may be formed by stretching a polyvinyl alcohol film in one direction and immersing it in a solution of iodine and / or a dichroic dye. In this case, iodine molecules and / or dichroic dye molecules are aligned in the stretching direction. Because the iodine molecules and dye molecules exhibit dichroism, they absorb light vibrating in the stretching direction and transmit light vibrating perpendicularly to the stretching direction.

[0084] The phase retardation layer (PRL) 553 is disposed on one side of the polarizing layer 552 and may retard the phase of light reflected back by a metal layer or the like inside the display panel. For example, the phase retardation layer 553 may retard the phase of the reflected light by about λ / 4 and circularly polarize the light, thereby reducing the reflectivity of the light. In some embodiments, the phase retardation layer 553 has wavelength dependence, and the phase retardation value may decrease toward shorter wavelengths. As shown in the drawing, the phase retardation layer 553 may be disposed below the polarizing layer 552.

[0085] The first protective layer 551 and the second protective layer 554 may serve as protective layers that support the polarizing layer 552 and the phase delay layer 553 and enhance the mechanical strength of the polarizing layer 552 and the phase delay layer 553. The first protective layer 551 may be disposed below the phase delay layer 553. The second protective layer 554 may be disposed above the polarizing layer 552. Alternatively, the second protective layer 554 may be disposed between the polarizing layer 552 and the phase delay layer 553, and various other modifications are possible.

[0086] The first protective layer 551 and the second protective layer 554 may include triacetyl cellulose (TAC), cycloolefin polymer, or polymethyl methacrylate (PMMA).

[0087] The hard coating layer 555 also serves to protect the polarizing film layer 550 from external impacts. The hard coating layer 555 has a scratch-resistant function and may have a strength of approximately 3H to 9H. Since the hard coating layer 555 is disposed above the transparent layer 520 on which the plurality of light-blocking lines 530 are disposed, the transparent layer 520 may also be protected by the hard coating layer 555.

[0088] A protective film 560 may be disposed on the hard coating layer 555. The protective film 560 is a temporary film for protecting the polarizing film layer 550 and may be removed later.

[0089] In this embodiment, the transparent layer 520 having the plurality of light-blocking lines 530 disposed thereon may be disposed in direct contact with the first protective layer 551. That is, in this embodiment, the transparent layer 520 is disposed directly on one side of the polarizing film layer 550, eliminating the need for a separate base film for forming the transparent layer 520 and the plurality of light-blocking lines 530. As a result, the overall thickness of the light control polarizing film is reduced, and a dual phase due to birefringence of the base film is not exhibited.

[0090] 6A to 6E are schematic cross-sectional views sequentially illustrating a method for manufacturing a light control polarizing film 500 according to one embodiment.

[0091] 6A, a polarizing film 550' is prepared by attaching a protective film 560 to a polarizing film layer 550. The polarizing film 550' is also a roll-type polarizing film obtained through a roll-to-roll process. In this case, the polarizing film 550' does not include an adhesive layer.

[0092] Next, the transparent layer 520 is formed on the surface of the polarizing film layer 550 where the protective film 560 is not attached. That is, the transparent layer 520 is formed on the underside of the first protective layer 551 of the polarizing film layer 550. The transparent layer 520 is a resin having high light transmittance and is also a material that is cured by UV. For example, the transparent layer 520 may include a cellulose resin, a polyolefin resin, a polyester resin, polystyrene, polyurethane, polyvinyl chloride, an acrylic resin, etc.

[0093] 6B, the mold MD having the plurality of protrusions MDa is pressed against the transparent layer 520. As a result, a plurality of grooves GV corresponding to the plurality of protrusions MDa may be formed in the transparent layer 520. At this time, UV may be irradiated from the upper surface of the protective film 560 to harden the transparent layer 520. The grooves GV may have an area that narrows from the lower surface to the upper surface of the transparent layer 520.

[0094] 6C, a light-blocking material is then filled into the grooves GV formed in the transparent layer 520 to form a plurality of light-blocking lines 530. For example, the light-blocking material may include a black dye. The light-blocking lines 530 may be formed by coating the entire surface of the transparent layer 520 with a light-blocking material and then removing the light-blocking material from areas other than the grooves GV to form black ink light-blocking lines 530 in each of the grooves. After filling the grooves GV with the light-blocking material, the light-blocking material may be cured using UV curing or thermal curing. The path of light emitted from the display layer 200 may be controlled depending on the arrangement of the light-blocking lines 530.

[0095] 6D, an adhesive layer 510 and a temporary protective film SF are formed on the transparent layer 520 and the plurality of light-shielding lines 530. The adhesive layer 510 is a pressure-sensitive adhesive (PSA), and the temporary protective film SF is a non-sticky film.

[0096] Referring to FIG. 6E, the temporary protective film SF can be removed just before being attached to the encapsulating member 300 (see FIG. 4A), and the adhesive layer 510 can be brought into contact with the encapsulating member 300, after which the light control polarizing film 500 can be attached to the top of the encapsulating member 300.

[0097] FIG. 7 is a plan view showing a part of the light control polarizing film.

[0098] 7, a plurality of light-blocking lines 530 may be arranged to extend in a certain direction in the light-controlling polarizing film 500. The certain direction may also be the direction of the absorption axis (AB axis) of the light-controlling polarizing film 500. That is, the plurality of light-blocking lines 530 may be arranged to extend in the direction of the absorption axis (AB axis).

[0099] The light control polarizing film 500 may have a horizontal side in a first direction (e.g., x direction) and a vertical side in a second direction (e.g., y direction). The horizontal and vertical sides of the light control polarizing film 500 may correspond to the horizontal and vertical sides of the display area DA (see FIG. 3 ) of the display device, respectively.

[0100] The absorption axis (AB axis) of the light control polarizing film 500 may be formed at an angle of about 5° to 7° with respect to a first direction (e.g., x direction). The plurality of light-shielding lines 530 may extend in the direction of the absorption axis (AB axis), and may extend in a state inclined at an angle of about 5° to 7° with respect to the first direction (e.g., x direction).

[0101] The plurality of light-shielding lines 530 extend in the direction of the absorption axis (AB_axis) and have an inclination of about 5° to 7° in the first direction in order to prevent or reduce the occurrence of moire. Meanwhile, in the light control polarizing film 500 of an embodiment of the present invention, the plurality of light-shielding lines 530 are formed directly on the polarizing film layer 550, which makes it easy to form the plurality of light-shielding lines 530 so that they coincide with the direction of the absorption axis (AB_axis).

[0102] The light-shielding lines 530 may be spaced apart from one another at a first interval 530int, which is a regular interval. The first interval 530int is also the shortest distance between adjacent light-shielding lines. For example, the first interval 530int is also the distance from the edge of a first light-shielding line to the edge of a second light-shielding line adjacent to the first light-shielding line. The first interval 530int may range from 30 μm to 60 μm. Meanwhile, the width (530w) of the light-shielding line 530 is also approximately 10 μm.

[0103] FIG. 8 is a plan view schematically showing a display device 1 according to one embodiment of the present invention.

[0104] 8, the display device 1 may include a display area DA and a non-display area NDA. The display device 1 may include a substrate 100 and a multilayer film on the substrate 100. The display area DA and the non-display area NDA may be defined in the substrate 100 and / or the multilayer film. For example, the display area DA and the non-display area NDA may be defined in the substrate 100. That is, the substrate 100 may include the display area DA and the non-display area NDA.

[0105] A plurality of sub-pixels P may be arranged in the display area DA. The sub-pixels P may display an image. The sub-pixels P may be connected to scan lines SL extending in a first direction (e.g., x-direction) and data lines DL extending in a second direction (e.g., y-direction).

[0106] The non-display area NDA may be disposed outside the display area DA. The non-display area NDA may at least partially surround the display area DA. In one embodiment, the non-display area NDA may entirely surround the display area DA. A scan driver (not shown) that provides scan signals to each sub-pixel P may be disposed in the non-display area NDA. A data driver (not shown) that provides data signals to the sub-pixel P may be disposed in the non-display area NDA. The non-display area NDA may include a pad area (not shown). In one embodiment, pads (not shown) may be disposed in the pad area. The pads may be exposed and not covered by an insulating layer, and may be electrically connected to a printed circuit board or a driver IC. Signals and / or voltages transmitted from the printed circuit board or the driver IC via the pads may be transmitted to the sub-pixels P disposed in the display area DA via wiring (not shown) connected to the pads.

The pixel circuit PC may include a driving transistor T1, a switching transistor T2, and a storage capacitor Cst. The sub-pixel P may emit, for example, red, green, or blue light, or red, green, blue, or white light, via the OLED.

[0109] The switching transistor T2 is connected to the scan line SL and the data line DL and may transmit a data signal or a data voltage input from the data line DL to the driving transistor T1 based on a scan signal or a switching voltage input from the scan line SL. The storage capacitor Cst is connected to the switching transistor T2 and the driving voltage line PL and may store a voltage corresponding to the difference between the voltage transmitted from the switching transistor T2 and the first power supply voltage ELVDD supplied to the driving voltage line PL.

[0110] The driving transistor T1 is connected to the driving voltage line PL and the storage capacitor Cst and may control a driving current flowing from the driving voltage line PL to the organic light emitting diode (OLED) in response to the voltage stored in the storage capacitor Cst. The organic light emitting diode (OLED) may emit light having a predetermined brightness in response to the driving current. A common electrode (e.g., a cathode) of the organic light emitting diode (OLED) may be supplied with a second power supply voltage ELVSS.

[0129] In some embodiments, a capping layer (not shown) may further be disposed on the counter electrode 223. The capping layer may include LiF, an inorganic material, or / and an organic material.

[0130] The sealing member may be disposed on the display layer 200. Referring to FIG. 10, the sealing member may include a sealing layer 300L. The sealing layer 300L may include at least one inorganic sealing layer and at least one organic sealing layer. FIG. 10 shows that the sealing layer 300L includes a first inorganic sealing layer 310, an organic sealing layer 320, and a second inorganic sealing layer 330, which are sequentially stacked. In this case, the thickness of the sealing layer 300L may be approximately 10 μm.

[0131] 11, the sealing member may include a sealing substrate 340. In one embodiment, the thickness of the sealing substrate 340 in the third direction (eg, the z-direction) is also about 300 μm.

[0132] A light control polarizing film 500 may be disposed on the encapsulation substrate 340. The light control polarizing film 500 may be attached onto the encapsulation layer 300L by an adhesive layer 510 disposed below the light control polarizing film 500.

[0133] The light control polarizing film 500 includes an adhesive layer 510, a transparent layer 520, a plurality of light-shielding lines 530, and a polarizing film layer 550. The polarizing film layer 550 may include a first protective layer 551, a phase retardation layer 553, a polarizing layer 552, a second protective layer 554, and a hard coating layer 555.

[0134] The transparent layer 520 may include a plurality of grooves. The grooves may be arranged at regular intervals. A plurality of light-shielding lines 530 may fill the grooves. The light-shielding lines 530 may be spaced apart from one another at a first interval 530int, which may be a regular interval. The first interval 530int may range from 30 μm to 60 μm. The width (530w) of the light-shielding lines 530 in the second direction (e.g., the y direction) may be about 10 μm. The light-shielding lines 530 may include a light-shielding material. In a cross-sectional view, the inclination of the light-shielding lines 530 with respect to the top surface of the substrate 100 is about 3.1°. The taper angle of the side of the grooves arranged in the transparent layer 520 with respect to the top surface of the substrate 100 is also about 3.1°.

[0135] The width Ew of the light emitting region in the second direction is also an integer multiple of the first interval 530int, which is the interval between the light blocking lines 530. In this case, the occurrence of moire can be prevented or reduced, and the quality of the display device 1 can be improved.

[0136] In addition, in the embodiment of the present invention, the size of the double layer can be minimized by minimizing the vertical distance d between the light emitting layer 222b and the plurality of light blocking lines 530. Therefore, the quality of the display device 1 can be improved.

[0137] The size of the dual phase increases as the vertical distance d between the light emitting layer 222b and the plurality of light-shielding lines 530 increases. That is, the width (Gw) of the dual phase may satisfy the following formula:

[0138] Gw = tanθ x d (θ is the viewing angle, d is the vertical distance between the light-emitting layer and the light-shielding line)

[0139] Generally, when a polarizing film is separately provided, the polarizing film is first attached to the encapsulant, and then a light path control film having a plurality of light-blocking lines for controlling the light path is attached on top of the polarizing film. In this case, the distance between the light-emitting layer 222b and the plurality of light-blocking lines 530 is about 740 μm. In this case, the width of the dual layer is also about 539 μm.

[0140] To reduce the size of such double layers, it may be considered to place multiple light-blocking lines 530 close to the display layer 200 .

[0141] However, even if the transparent layer 520 having the plurality of light-blocking lines 530 is formed on a separate base film and placed closer to the display layer than the polarizing film, it is difficult to eliminate the dual phase due to the thickness of the base film and the birefringence caused by the base film.

[0142] In an embodiment of the present invention, a polarizing film layer 550 is disposed on top of the plurality of light-shielding lines 530, and the plurality of light-shielding lines 530 are formed directly on the polarizing film layer 550 instead of on a base film. This significantly reduces the distance d between the light-emitting layer 222b and the plurality of light-shielding lines 530, and eliminates the need for a base film that induces birefringence, thereby minimizing the visibility of the dual phase.

[0143] In some embodiments, the distance between the light-emitting layer 222b and the plurality of light-shielding lines 530 is approximately 10 μm to 300 μm. In this case, the width of the dual layer is approximately 7 μm to 218 μm. That is, embodiments of the present invention may significantly reduce the vertical distance d between the light-emitting layer 222b and the plurality of light-shielding lines 530, thereby minimizing the width of the dual layer and making it invisible to the user.

[0144] Although the present invention has been described based on one embodiment shown in the drawings, it will be understood that this is merely an example, and that various modifications and variations of the embodiment are possible by those skilled in the art. Therefore, the true technical scope of protection of the present invention should be determined by the technical spirit of the claims.
