[0048] Embodiments of the inventive concept will be described more fully below with reference to the accompanying drawings. Throughout the drawings, the same reference numerals may refer to the same elements.

[0049] It will be understood that the terms “first,” “second,” “third,” etc., are used herein to distinguish one element from another, and these elements are not limited by these terms. Thus, a “first” element in one embodiment may be described as a “second” element in another embodiment.

[0050] It should be understood that, unless the context clearly indicates otherwise, the description of a feature or aspect within each embodiment should generally be considered applicable to other similar features or aspects in other embodiments.

[0051] As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “one,” and “the” are intended to include the plural forms as well.

[0052] As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items. When appearing before / after a list of elements, expressions such as “at least one of…” modify the entire list of elements, rather than a single element in the list.

[0053] For ease of description, spatial relative terms such as “below,” “under,” “below,” “below,” “above,” and “above” may be used herein to describe the relationship of one element or feature to another element (or more elements) or feature (or more features) as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the spatial relative terms are also intended to cover different orientations of the device in use or operation. For example, if the device is flipped in the drawings, an element described as “below,” “below,” or “below” other elements or features will subsequently be oriented “above” other elements or features. Thus, the example terms “below” and “below” can cover both above and below orientations.

[0054] It will be understood that when a component is referred to as being "on" another component, "connected to" another component, "coupled to" another component, or "adjacent to" another component, the component may be directly on, connected to, coupled to, or adjacent to the other component, or there may be intermediary components. It will be understood that when a component is referred to as being "between" two components, the component may be the only component between the two components, or there may be one or more intermediary components. It will also be understood that when a component is referred to as "covering" another component, the component may be the only component covering the other component, or one or more intermediary components may also cover the other component. Other terms used to describe relationships between components should be interpreted in the same manner.

[0055] In this document, when two or more elements or values ​​are described as substantially the same or approximately equal to each other, it will be understood that the elements or values ​​are the same, are equal to each other within measurement error, or, if measurably unequal, are sufficiently close in value to be functionally equal, as will be understood by those skilled in the art. For example, taking into account the measurements discussed and the errors associated with the measurement of a particular quantity (e.g., limitations of the measurement system), the term “approximately” as used herein includes the stated value and means within an acceptable range of deviation from the particular value as determined by those skilled in the art. For example, “approximately” may mean within one or more standard deviations as understood by those skilled in the art, such as ±30%, ±20%, ±10%, or ±5% of the stated value. Furthermore, it will be understood that while a parameter may be described herein as having a particular value “approximately”, according to embodiments, the parameter may be precisely the particular value or approximately the particular value within measurement error as will be understood by those skilled in the art. These terms, and other uses of similar terms, used to describe the relationships between components, should be interpreted in the same way.

[0056] It will be understood that, when used in this specification, the terms “comprising” or “including” indicate the presence of the stated features, integrals, steps, operations, elements, components, or combinations thereof, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0057] Embodiments of this invention relate to a display device, a method of manufacturing the display device, and an electronic device that utilize a light control layer that can improve display quality by enhancing light-blocking properties. The light control layer may be disposed on a display element layer and may include an organic film defining a first region and a second region, a light-blocking component filling the first region, and an optical pattern disposed in the second region. The organic film, the light-blocking component, and the optical pattern may collectively form a tapered light-blocking structure that can effectively limit light emission outside a predetermined angular range, thereby improving privacy and reducing reflection.

[0058] Embodiments of this invention can utilize a unique geometric design in which the width of the organic film decreases as the structure moves away from the display element layer, while the width of the light-blocking component increases. This reverse taper shape provides excellent light-blocking performance and reduces light leakage. Optical patterns including tilted surfaces can improve the ability of the light control layer to selectively block light while maintaining high display quality.

[0059] The innovative structure and related manufacturing method provided by embodiments of the present invention enable the production of display devices with improved performance. The innovative structure and related manufacturing method may involve multi-step etching and precise deposition of light-blocking components and optical patterns. For example, the embodiments can be used in vehicles, consumer electronics, and other devices where controlled light emission and improved privacy features are emphasized.

[0060] In the following description, a display device according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a perspective view showing a display device according to an embodiment.

[0061] Reference Figure 1 The display device DD according to the embodiments can be activated in response to an electrical signal. For example, the display device DD can be a device such as a television, monitor, billboard, tablet computer, vehicle navigation unit, personal computer, laptop computer, personal digital terminal, game console, smartphone, and camera. It will be understood that these are merely examples, and the display device DD can be used as other display devices without departing from the spirit of the invention. In this specification, an electronic device can be or may include the display device DD.

[0062] The display device DD can display an image IM via a display surface DD-IS. The image IM can include not only moving images (e.g., video) but also still images. The display surface DD-IS can be parallel to the plane defined by a first direction DR1 and a second direction DR2. Figure 1A display device DD is shown, providing a flat display surface DD-IS. However, embodiments of the present invention are not limited thereto. For example, according to embodiments, the display device DD may also include a curved display surface or a three-dimensional display surface. The three-dimensional display surface may also include multiple display areas pointing in different directions.

[0063] The display surface DD-IS may include a display area DD-DA and a non-display area DD-NDA. The display device DD can display an image IM through the display area DD-DA. The non-display area DD-NDA may be adjacent to the display area DD-DA, and the image IM is not displayed in the non-display area DD-NDA. The non-display area DD-NDA may surround the display area DD-DA. However, Figure 1 As shown by example, and according to the embodiment, the non-display area DD-NDA may also be set to be adjacent to only one side of the display area DD-DA, or the non-display area DD-NDA may be omitted.

[0064] exist Figure 1 The following figures illustrate a first direction axis DR1, a second direction axis DR2, and a third direction axis DR3. The directions indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3 described herein may be relative and can therefore be changed to other directions. Furthermore, the directions indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3 may be referred to as the first direction DR1, the second direction DR2, and the third direction DR3, and may be represented by the same reference numerals or symbols. In this specification, the first direction axis DR1 and the second direction axis DR2 may be orthogonal to each other, and the third direction axis DR3 may be the normal direction of the plane defined by the first direction axis DR1 and the second direction axis DR2.

[0065] The thickness direction of the display device DD corresponds to the third directional axis DR3. The upper side (or upper surface) refers to the side closer to the display surface DD-IS, while the lower side (or lower surface) refers to the side farther from the display surface DD-IS, both defined relative to the third directional axis DR3. A cross-section is a surface parallel to the thickness direction DR3 (i.e., the third directional axis DR3), while a plane is a surface perpendicular to the thickness direction DR3. The plane is defined by the first directional axis DR1 and the second directional axis DR2.

[0066] In this specification, the phrase "an element overlaps with another element" means "overlaps on a plane". The situation where an element overlaps with another element is not limited to the case where the two elements have the same shape or area, but also includes the case where the two elements have different shapes and / or areas.

[0067] Figure 2 It shows along Figure 1A cross-sectional view of a portion of the line I-I'. Figure 2 It may be a cross-sectional view showing the display device DD according to an embodiment.

[0068] Reference Figure 2 The display device DD may include a display module DM, a light control layer RCL disposed on the display module DM, and a window component WM disposed on the light control layer RCL. The display module DM may include a display panel DP and an input sensing layer ISP disposed on the display panel DP.

[0069] The display panel DP can basically include driving light-emitting elements ED-1, ED-2, and ED-3 (see...). Figure 4 It comprises at least one capacitor and multiple transistors. For example, each light-emitting element described herein can be implemented using an organic light-emitting diode (OLED). However, the embodiments are not limited thereto. The display panel DP can be essentially an image-generating IM (see [link to OLED]). Figure 1 The display panel (DP) is a component of the LED display. The DP can be a light-emitting display panel. For example, the DP can be an organic light-emitting display panel, an inorganic light-emitting display panel, a quantum dot display panel, a micro-light-emitting diode (LED) display panel, or a nano-LED display panel. The DP can be referred to as the display layer. The DP can include a substrate layer (BS), a circuit layer (DP-CL), a display element layer (DP-ED), and a packaging layer (TFE) stacked sequentially.

[0070] The substrate layer BS can be a component providing a substrate surface on which the circuit layer DP-CL is disposed. The substrate layer BS can be a rigid substrate or a flexible substrate that is bendable, foldable, rollable, etc. For example, the substrate layer BS can be a glass substrate, a metal substrate, a polymer substrate, etc. However, embodiments of the present invention are not limited thereto. For example, according to an embodiment, the substrate layer BS can be an inorganic substrate layer, an organic substrate layer, or a composite material layer.

[0071] The circuit layer DP-CL can be disposed on the substrate layer BS. For example, the circuit layer DP-CL may include an insulating layer, semiconductor patterns, conductive patterns, signal lines, etc. The insulating layer, semiconductor layer, and conductive layer are formed on the substrate layer BS by processes such as coating and deposition, and then the insulating layer, semiconductor layer, and conductive layer can be selectively patterned by performing photolithography multiple times, thereby forming semiconductor patterns, conductive patterns, and signal lines included in the circuit layer DP-CL.

[0072] The display element layer DP-ED can be disposed on the circuit layer DP-CL. The display element layer DP-ED can include light-emitting elements ED-1, ED-2, and ED-3 (see...). Figure 4For example, the display element layer DP-ED may include organic light-emitting materials, inorganic light-emitting materials, organic-inorganic light-emitting materials, quantum dots, or quantum rods. For example, the display element layer DP-ED may include micro-LEDs or nano-LEDs.

[0073] A TFE encapsulation layer can be applied to the DP-ED display element layer. The TFE encapsulation layer protects the DP-ED display element layer from moisture, oxygen, and foreign matter such as dust particles.

[0074] An input sensing layer (ISP) can be disposed on a display panel (DP). The ISP can detect external input, convert the detected external input into a predetermined input signal, and provide the input signal to the display panel (DP). For example, in a display device (DD) according to an embodiment, the ISP can be a touch sensing component that detects touch. The ISP can recognize direct touch by a user, indirect touch by a user, direct touch by an object, indirect touch by an object, etc.

[0075] The input sensing layer (ISP) can detect at least one of the location and intensity (pressure) of an externally applied touch. The display panel (DP) can receive the input signal from the ISP and generate an image (IM) corresponding to the input signal. For example, the ISP can detect external input capacitively. However, this is presented as an example, and the driving method of the ISP is not limited to this.

[0076] The input sensing layer (ISP) can be formed on the display panel (DP) via a continuous process. In this case, the input sensing layer (ISP) can be directly disposed on the display panel (DP). That is, in an embodiment, an additional adhesive component may not be disposed between the input sensing layer (ISP) and the display panel (DP). In an embodiment, the input sensing layer (ISP) can also be bonded to the display panel (DP) via an adhesive component. The adhesive component may include a typical adhesive or bonding agent.

[0077] In this specification, when an element is referred to as being directly mounted / directly formed on another element, there is no intermediary element between the element and the other element. That is, the phrase "element 'directly mounted / directly formed on 'another element'" means "element 'in contact with 'another element'".

[0078] A light control layer (RCL) can limit the emission angle of light emitted from a display panel (DP). The RCL can absorb (or block) light propagating at angles outside a specific angular range and only allow light propagating at angles falling within that specific angular range to be emitted. For example, the RCL can be a light control film (LCF) applied to a display device for a vehicle. The LCF prevents light emitted from the display device (DD) from being reflected at the windshield of a car and obstructing the driver's view. In embodiments, the RCL can be a component provided to protect the user's personal privacy, allowing the image IM (see...) to... Figure 1 It is invisible to others around the user located on the display device DD. For example, the light control layer RCL can be directly set on the display module DM.

[0079] The window component WM can be disposed on the display module DM. The window component WM may include a window WP and an adhesive layer AP. The window component WM may also include at least one functional layer provided on the window WP. For example, the functional layer may be a hard coating layer, an anti-fingerprint coating layer, etc. However, embodiments of the present invention are not limited thereto.

[0080] The window WP may include an optically transparent insulating material. The window WP may be a glass substrate or a polymer substrate. For example, in an embodiment, the window WP may be a tempered glass substrate that has undergone a strengthening treatment. For example, in an embodiment, the window WP may be formed of polyimide, polyacrylate, polymethyl methacrylate, polycarbonate, polyethylene naphthalate, polyvinylidene chloride, polyvinylidene fluoride, polystyrene, ethylene vinyl alcohol copolymer, or combinations thereof. However, this is presented by way of example, and the materials included in the window WP are not limited thereto.

[0081] An adhesive layer AP can be disposed between the display module DM and the window WP. Components adjacent to the window WP (e.g., the display module DM and the light control layer RCL) can be bonded to the window WP via the adhesive layer AP. The adhesive layer AP can include, but is not limited to, typical adhesives such as pressure-sensitive adhesive (PSA), optically clear adhesive (OCA), and optically clear resin (OCR). Unlike what is shown, in this embodiment, the adhesive layer AP may also be omitted.

[0082] Figure 3A This is a plan view showing a portion of a display device according to an embodiment. Specifically, Figure 3A This is an enlarged plan view showing a portion of the display area DD-DA according to an embodiment. (Refer to...) Figure 3A The display area DD-DA can be divided into the light-emitting area PXA and the peripheral area NPXA. The peripheral area NPXA surrounds the light-emitting area PXA.

[0083] The light-emitting region PXA can be provided as multiple light-emitting regions emitting light with different wavelength ranges. The light-emitting region PXA may include a first light-emitting region PXA-B, a second light-emitting region PXA-G, and a third light-emitting region PXA-R. For example, the first light-emitting region PXA-B may emit blue light, the second light-emitting region PXA-G may emit green light, and the third light-emitting region PXA-R may emit red light. However, embodiments of the inventive concept are not limited thereto. For example, according to an embodiment, the first light-emitting region PXA-B, the second light-emitting region PXA-G, and the third light-emitting region PXA-R may also emit light of a color other than red, green, and blue.

[0084] In the luminescent region PXA, the first luminescent region PXA-B, which emits blue light, can have the largest area, and the second luminescent region PXA-G, which emits green light, can have the smallest area. In this case, the area is considered to be the area when viewed on a plane. However, this is presented as an example, and the areas of the first luminescent region PXA-B, the second luminescent region PXA-G, and the third luminescent region PXA-R are not limited to this.

[0085] Figure 3A The diagram shows a first luminous area PXA-B and a third luminous area PXA-R alternately arranged in a first row along a first direction DR1, and a second luminous area PXA-G arranged in a second row spaced apart from the first luminous areas PXA-B and the third luminous area PXA-R. However, this is presented as an example, and the arrangement of the first luminous area PXA-B, the second luminous area PXA-G, and the third luminous area PXA-R is not limited to this. Furthermore, in a plane, the shapes of the first luminous area PXA-B, the second luminous area PXA-G, and the third luminous area PXA-R are not limited to the shapes shown in the diagram and can be defined as shapes different from those shown in the diagram.

[0086] The peripheral region NPXA can be the region between adjacent light-emitting regions PXA-B, PXA-G, and PXA-R, and the peripheral region NPXA can be the pixel-defined film PDL, which will be described in further detail below (see [link to PXA-B]). Figure 4 The corresponding regions are the first light-emitting region PXA-B, the second light-emitting region PXA-G, and the third light-emitting region PXA-R. These regions can be respectively associated with the first light-emitting element ED-1, which will be described in further detail below (see [link to relevant documentation]). Figure 4 ), second light-emitting element ED-2 (see Figure 4 ) and the third light-emitting element ED-3 (see Figure 4 ).

[0087] Figure 3B This is a plan view showing a portion of a display device according to an embodiment. Specifically, Figure 3BThis is an enlarged plan view showing a portion of the display area DD-DAa according to an embodiment of the present invention. (Refer to...) Figure 3B The first group of PXG1 and the second group of PXG2 can be set in the display area DD-DAa.

[0088] The first luminescent region PXA-B, the second luminescent region PXA-G, and the third luminescent region PXA-R can form a first group PXG1 and a second group PXG2. On a plane, the first group PXG1 and the second group PXG2 can be alternately arranged along a first direction DR1. Furthermore, on a plane, the first group PXG1 and the second group PXG2 can be alternately arranged along a second direction DR2.

[0089] The first group of PXG1 and the second group of PXG2 may each include a first luminous area PXA-B, a second luminous area PXA-G, and a third luminous area PXA-R. According to an embodiment, in the first direction DR1, the edge of the first luminous area PXA-B of the first group of PXG1 is not aligned with the edge of the first luminous area PXA-B of the second group of PXG2. In the first group of PXG1, the edge of the first luminous area PXA-B can be aligned with the edge of the second luminous area PXA-G. In this case, the edges of the first luminous area PXA-B and the second luminous area PXA-G can be aligned with each other in the first direction DR1. In the second group of PXG2, the edge of the first luminous area PXA-B can be aligned with the edge of the third luminous area PXA-R.

[0133] Figure 5 It is shown Figure 4 An enlarged cross-sectional view of region AA'. (Refer to...) Figure 5 The first width W1 of the organic film TMA can decrease as the organic film TMA is positioned further and further away from the display module DM. The second width W2 of the light-blocking component BMA can increase as the light-blocking component BMA is positioned further and further away from the display module DM. For example, the first width W1 of the organic film TMA can be positioned further away from the display element layer DP-ED along the thickness direction DR3 (see...). Figure 4 The first width W1 and the second width W2 of the light-blocking component BMA gradually decrease, and the second width W2 can gradually increase along the thickness direction DR3 away from the display element layer DP-ED. The first width W1 and the second width W2 can each be in a direction perpendicular to the thickness direction DR3.

Figure 4The second width W2 of the light-blocking component BMA gradually decreases, and the light-blocking component BMA can be positioned further and further away from the display element layer DP-ED included in the display module DM (see...).

[0134] A first region T-OH1 and a second region T-OH2 can be defined within the organic membrane TMA, and the first region T-OH1 and the second region T-OH2 can be formed during different operations during the manufacturing process. A first preliminary organic membrane P1-TMA with a predetermined thickness can be formed (see...). Figure 10 ), and then can be achieved by processing the first preliminary organic membrane P1-TMA (see Figure 10 An etching process is performed to form a second preliminary organic film P2-TMA having a first region T-OH1 confined therein (see [link]). Figure 11 This can be achieved by examining the second preliminary organic membrane P2-TMA (see...). Figure 11 An etching process is performed to form an organic film TMA having a first region T-OH1 and a second region T-OH2 defined therein. When etching is performed on a first preliminary organic film P1-TMA and a second preliminary organic film P2-TMA having predetermined thicknesses (see...),... Figure 10 and Figure 11 During the etching process, the etching width can vary depending on the depth. Due to the characteristics of the etching process, the greater the depth of a component with a predetermined thickness, the more the straightness of the etching direction deteriorates, leading to a decrease in the etching width. The etching width refers to the width in a direction perpendicular to the thickness direction DR3. Points with large depths are considered to be areas located in the lower portion of the thickness direction DR3, and points with small depths are considered to be areas located in the upper portion of the thickness direction DR3. When the etching process is performed in the direction from the upper portion to the lower portion, due to the characteristics of the etching process, the etching width decreases as the etching process proceeds downwards.

[0135] The first region T-OH1 and the second region T-OH2 can be spaced apart from each other in a direction perpendicular to the thickness direction DR3. The first region T-OH1 and the second region T-OH2, formed by an etching process, can each have a width that increases with increasing distance from the display module DM. Therefore, the first width W1 of the organic film TMA having the first region T-OH1 and the second region T-OH2 defined therein can decrease with increasing distance from the display module DM. The angle θ formed between a plane VP perpendicular to the thickness direction DR3 and the inner surface T_SF of the organic film TMA defining the second region T-OH2 is... T It can be approximately 87° to approximately 89°. Figure 5 The plane VP shown can be a virtual surface and is perpendicular to the thickness direction DR3.

[0136] The light-blocking component BMA can be configured to fill the first region T-OH1. The width of the first region T-OH1, formed by the etching process, can increase as the first region T-OH1 moves further away from the display module DM. Therefore, the light-blocking component BMA configured to fill the first region T-OH1 can have a second width W2 that increases as the first region T-OH1 is positioned further away from the display module DM.

[0137] In cross-section, the light-blocking component BMA can have an inverted trapezoidal (or reverse-tapered) shape including an inclined side surface B_SF. The light-blocking component BMA may include a lower surface B_DF adjacent to the display module DM, an upper surface B_UF disposed on the lower surface B_DF, and a side surface B_SF disposed between the lower surface B_DF and the upper surface B_UF. The lower surface B_DF, upper surface B_UF, and side surface B_SF can have an integral shape. The lower surface B_DF and upper surface B_UF of the light-blocking component BMA can be back-to-back with each other in the thickness direction DR3. In cross-section, the length DT2 of the upper surface B_UF of the light-blocking component BMA can be greater than the length DT1 of the lower surface B_DF of the light-blocking component BMA. The length DT2 of the upper surface B_UF and the length DT1 of the lower surface B_DF of the light-blocking component BMA can each be a length in a direction perpendicular to the thickness direction DR3.

[0138] The side surface B_SF of the light-blocking component BMA can be inclined relative to the thickness direction DR3. In the light-blocking component BMA, the angle formed between the side surface B_SF and the upper surface B_UF can be greater than approximately 0° and less than approximately 90°. In the light-blocking component BMA, the angle formed between the side surface B_SF and the upper surface B_UF can be the interior angle of a trapezoid. In cross-section, the side surface B_SF of the light-blocking component BMA can include a first side surface B_SF1 and a second side surface B_SF2.

[0139] The optical pattern LRP can be disposed parallel to the side surface B_SF of the light-blocking component BMA. The optical pattern LRP may include a first patterned portion L-P1 and a second patterned portion L-P2 extending from the first patterned portion L-P1 in a direction perpendicular to the thickness direction DR3. Furthermore, the optical pattern LRP may also include a third patterned portion L-P3 extending from the second patterned portion L-P2. The first patterned portion L-P1, the second patterned portion L-P2, and the third patterned portion L-P3 may have an integral shape.

[0140] The second region T-OH2 can be provided in multiple ways. The second region T-OH2 may include a first sub-region T-OH21 and a second sub-region T-OH22 that are spaced apart from each other in a direction perpendicular to the thickness direction DR3.

[0141] The first patterned portion L-P1 and the third patterned portion L-P3 may be portions disposed within the second region T-OH2 and inclined relative to the thickness direction DR3. The first patterned portion L-P1 and the third patterned portion L-P3 may be portions inclined in a direction neither perpendicular to nor parallel to the thickness direction DR3. One surface L_F1 of the first patterned portion L-P1 may be inclined relative to the thickness direction DR3. The first patterned portion L-P1 may be disposed within the first sub-region T-OH21. The first patterned portion L-P1 may be disposed on the inner surface T_SF of the organic film TMA defining the second region T-OH2. The first patterned portion L-P1 may be directly disposed on the inner surface T_SF of the organic film TMA defining the second region T-OH2. The first patterned portion L-P1 may be spaced apart from the second side surface B_SF2 of the light-blocking component BMA, and the first side surface B_SF1 of the light-blocking component BMA is between the first patterned portion L-P1 and the second side surface B_SF2 of the light-blocking component BMA. The first patterned portion L-P1 may be disposed parallel to the second side surface B_SF2 of the light-blocking component BMA. However, this is presented as an example, and according to an embodiment, the first patterned portion L-P1 may also not be parallel to the second side surface B_SF2 of the light-blocking component BMA.

[0142] The third patterned portion L-P3 can be disposed on the inner surface T_SF of the defined second region T-OH2 of the organic film TMA. The third patterned portion L-P3 can be disposed within the second sub-region T-OH22. The third patterned portion L-P3 can be spaced apart from the first side surface B_SF1 of the light-blocking component BMA, and the second side surface B_SF2 of the light-blocking component BMA is located between the third patterned portion L-P3 and the first side surface B_SF1 of the light-blocking component BMA. The third patterned portion L-P3 can be disposed parallel to the first side surface B_SF1 of the light-blocking component BMA. However, this is presented as an example, and according to an embodiment, the third patterned portion L-P3 may also not be parallel to the first side surface B_SF1 of the light-blocking component BMA.

[0143] The second patterned portion L-P2 can be disposed on the upper surface B_UF of the light-blocking component BMA. The second patterned portion L-P2 can contact the upper surface B_UF of the light-blocking component BMA. The second patterned portion L-P2 can overlap with the first region T-OH1. The second patterned portion L-P2 can extend parallel to a direction perpendicular to the thickness direction DR3. In cross-section, the first patterned portion L-P1, the second patterned portion L-P2, and the third patterned portion L-P3 can form a trapezoidal (or tapered) shape.

[0144] An optically patterned LRP, including portions inclined relative to the thickness direction DR3 (i.e., the first patterned portion L-P1 and / or the third patterned portion L-P3), can block light propagating at angles exceeding a specific angular range from being emitted. The optically patterned LRP can have a reflectivity of approximately 10% or less. For example, in an optically patterned LRP, each of the reflectivity including the specular component (SCI) and the reflectivity excluding the specular component (SCE) can be approximately 10% or less. An optically patterned LRP with a reflectivity of approximately 10% or less can exhibit excellent light-blocking performance.

[0145] Optical patterned LRPs can include at least one of metals and inorganic materials. For example, optical patterned LRPs can include at least one of Si-containing inorganic materials, In-containing inorganic materials, and aluminum (Al). However, this is presented as an example. For example, according to embodiments, metals or inorganic materials can be applied as forming materials to optical patterned LRPs as long as they have a reflectivity of about 10% or less.

[0146] In the cross-section, the organic film TMA, the light-blocking component BMA, and the optical pattern LRP can form a trapezoidal shape. A light-blocking component BMA, a portion of the organic film TMA adjacent to the light-blocking component BMA, and an optical pattern LRP adjacent to the light-blocking component BMA form a trapezoidal structure, and thus the trapezoidal structure can restrict the emission of light propagating at angles exceeding a specific angular range. Therefore, the light control layer RCL according to the embodiment, including the organic film TMA, the light-blocking component BMA, and the optical pattern LRP, can exhibit excellent light-blocking performance. A display device DD including the light control layer RCL according to the embodiment (see...) Figure 4 It can exhibit excellent display quality.

[0147] For example, according to an embodiment, in a cross-section, the organic film TMA, the light-blocking component BMA, and the optical pattern LRP can collectively form a trapezoidal structure, wherein a single light-blocking component BMA, adjacent portions of the organic film TMA, and adjacent optical pattern LRPs create a trapezoidal configuration. This configuration can effectively limit the emission of light propagating at angles outside a defined angular range. As a result, the light control layer RCL according to the embodiment, comprising the organic film TMA, the light-blocking component BMA, and the optical pattern LRP, can exhibit improved light-blocking capabilities. Therefore, the display device DD incorporating the light control layer RCL as described above can provide excellent display quality.

[0148] Conversely, display devices that do not include optical patterns and include a transmissive element (i.e., an organic film) and a light-blocking element (the light-blocking element is configured to fill an opening defined in the transmissive element and has an inverted trapezoidal shape) have reduced light-blocking performance. The light-blocking element with an inverted trapezoidal shape restricts the emission of light propagating at angles exceeding a certain angular range, but the restricted angular range is very small, leading to reduced light-blocking performance. The display device DD according to an embodiment includes an organic film TMA forming a trapezoidal shape, a light-blocking element BMA, and an optical pattern LRP, and can therefore exhibit excellent display quality.

[0149] For example, in an organic film TMA formed by performing a two-etching process, the organic film TMA is related to the display surface DD-IS (see...). Figure 1 The adjacent upper region can have a very small width. This upper region of the organic film TMA is adjacent to the upper surface B_UF of the light-blocking component BMA and can be used as the starting point for the etching process. In the region adjacent to the upper surface B_UF of the light-blocking component BMA, the organic film TMA can have a first width W1 of approximately 0. In the region adjacent to the upper surface B_UF of the light-blocking component BMA, the organic film TMA has a first width W1 of 0, and the optical pattern LRP can contact the light-blocking component BMA. Specifically, in the region adjacent to the upper surface B_UF of the light-blocking component BMA, the organic film TMA has a first width W1 of 0, and a portion of the first patterned portion L-P1 of the optical pattern LRP can contact the light-blocking component BMA. In the region adjacent to the upper surface B_UF of the light-blocking component BMA, the organic film TMA has a first width W1 of 0, and a portion of the third patterned portion L-P3 of the optical pattern LRP can contact the light-blocking component BMA.

[0150] The transmissive element VC can be spaced apart from the organic film TMA in a direction perpendicular to the thickness direction DR3, and the optical pattern LRP is disposed between the transmissive element VC and the organic film TMA. The transmissive element VC may include a first portion V-P1 and a second portion V-P2 extending from the first portion V-P1. The first portion V-P1 of the transmissive element VC can be spaced apart from the organic film TMA in a direction perpendicular to the thickness direction DR3, and the optical pattern LRP is disposed between the first portion V-P1 of the transmissive element VC and the organic film TMA. The width of the first portion V-P1 of the transmissive element VC can increase as the first portion V-P1 is positioned further away from the display module DM. The width of the first portion V-P1 of the transmissive element VC can be in a direction perpendicular to the thickness direction DR3.

[0151] The first portion V-P1 of the transmissive component VC can be configured to fill the remaining areas within the second region T-OH2, except for one area in which the optical pattern LRP is disposed. One area of ​​the second region T-OH2 can be the same as the area in which the first patterned portion L-P1 (or the third patterned portion L-P3) of the optical pattern LRP is disposed, and another area of ​​the second region T-OH2 can be the same as the area in which the first portion V-P1 of the transmissive component VC is disposed.

[0152] The second portion V-P2 of the transmissive component VC can be disposed on the organic film TMA and the light-blocking component BMA. The second portion V-P2 of the transmissive component VC can overlap with the organic film TMA and the light-blocking component BMA. For example, the second portion V-P2 of the transmissive component VC can be adjacent to the display element layer DP-ED (see [link to display element layer]). Figure 4 They completely overlap.

[0153] Figure 6 and Figure 7 This is a cross-sectional view showing a display device according to an embodiment. In the following, for ease of explanation, regarding... Figure 6 and Figure 7 The description can omit the previous references. Figures 1 to 5 Further description of the components and technologies described.

[0154] and Figure 4 Compared to the display device DD shown, Figure 6 The display device DD-a shown is different from the display device DD in terms of the optical pattern LRP-a. Figure 6 The optical pattern LRP-a shown does not include the second patterned portion L-P2 (see [link]). Figure 5 ) and the third patterned part L-P3 (see Figure 5 ), and includes only the first patterned portion L-P1 (see Figure 5The optical pattern LRP-a can be applied only to the first side surface B_SF1 of the light-blocking component BMA (see...). Figure 5 It is set on the light-blocking component BMA, and not set on the upper surface B_UF (see Figure 5 ) and the second side surface B_SF2 of the light-blocking component BMA (see Figure 5 )superior. Figure 6 The optical pattern LRP-a shown does not overlap with the light-blocking component BMA. The upper surface of the optical pattern LRP-a can be disposed on substantially the same plane as the upper surface of the organic film TMA.

[0155] and Figure 4 Compared to the display device DD shown, Figure 7 The display device DD-b shown is different from the display device DD in terms of the transmission component VC-a. Figure 7 The transmission component VC-a shown may consist only of the first part V-P1 (see...) Figure 5 ), and does not include Part II V-P2 (see Figure 5 ). Figure 7 The transmission component VC-a shown does not overlap with the light blocking component BMA.

[0156] Figure 8 This is a view showing a vehicle in which a display device according to an embodiment is provided. Specifically, Figure 8 This is a view of a vehicle AM ​​in which a first display device DD-1, a second display device DD-2, a third display device DD-3, and a fourth display device DD-4 are installed. At least one of the first display device DD-1, the second display device DD-2, the third display device DD-3, and the fourth display device DD-4 may similarly include the above-mentioned references. Figures 1 to 7 The components of the display devices DD, DD-a, and Dd-b according to the embodiments are described.

[0157] Figure 8The vehicle AM ​​shown is a car, but this is presented as an example, and the embodiments are not limited thereto. For example, according to the embodiments, the first display device DD-1, the second display device DD-2, the third display device DD-3, and the fourth display device DD-4 can also be installed in other means of transportation such as bicycles, motorcycles, trains, ships, airplanes, etc. Furthermore, at least one of the first display device DD-1, the second display device DD-2, the third display device DD-3, and the fourth display device DD-4, which includes the same components as the display device DD according to the embodiments, can also be used in personal computers, laptop computers, personal digital terminals, game consoles, portable electronic devices, televisions, monitors, outdoor billboards, etc. Moreover, these are merely presented as examples, and at least one of the first display device DD-1, the second display device DD-2, the third display device DD-3, and the fourth display device DD-4, which includes the same components as the display device DD according to the embodiments, can be used in other electronic devices.

[0158] Reference Figure 8 The vehicle AM ​​may include a steering wheel HA and a gearshift GR for operating the vehicle AM. The vehicle AM ​​may include a windshield GL oriented towards the driver.

[0159] The first display device DD-1 may be located in a first area overlapping with the steering wheel HA. For example, the first display device DD-1 may be a digital instrument cluster displaying first information about the vehicle's AM. The first information may include a first scale indicating the vehicle's AM speed, a second scale indicating the engine speed (e.g., revolutions per minute (RPM)), and an image indicating fuel status, etc. The first and second scales may be displayed as digital images.

[0160] The second display device DD-2 can be disposed in a second area facing the driver's seat and overlapping the windshield GL. The driver's seat can be a seat with the steering wheel HA located nearby. For example, the second display device DD-2 can be a head-up display (HUD) displaying second information about the vehicle's AM. The second display device DD-2 can be optically transparent. For example, the second information can include a number indicating the vehicle's AM speed, and also information such as the current time. Unlike the example shown, the second information of the second display device DD-2 can also be projected onto the windshield GL for display.

[0161] The third display device DD-3 can be located in a third zone adjacent to the gear shift GR. For example, the third display device DD-3 can be a central information display (CID) for the vehicle, located between the driver's seat and the passenger seat, displaying third information. The passenger seat can be a seat separated from the driver's seat, and the gear shift GR is located between the passenger seat and the driver's seat. The third information may include information about road conditions (e.g., navigation information), music or radio playback, video playback, temperature inside the vehicle's AM system, etc.

[0162] The fourth display device DD-4 can be located in a fourth zone, spaced apart from the steering wheel HA and gear shift GR, and adjacent to the side portion of the vehicle AM. For example, the fourth display device DD-4 can be a digital side mirror displaying fourth information. The fourth display device DD-4 can display external images captured by a camera module CM located outside the vehicle AM. The fourth information may include the external images from the vehicle AM.

[0163] The first to fourth information described above are presented as examples, and the first display device DD-1, the second display device DD-2, the third display device DD-3, and the fourth display device DD-4 can also display information about the interior and exterior of the vehicle AM. The first to fourth information may include different information. However, embodiments of the inventive concept are not limited thereto, and some segments of the first to fourth information may include the same information.

[0164] The display device according to the embodiment can be formed by the method of manufacturing the display device according to the embodiment. Figure 9A and Figure 9B This is a flowchart illustrating a method for manufacturing a display device according to an embodiment. Figures 10 to 14 This is a schematic view illustrating the manufacturing operation of a display device according to an embodiment. In the following, regarding... Figures 9A to 14 For ease of explanation, previous references may be omitted from the description. Figures 1 to 8 Further description of the components and technologies described.

[0165] Reference Figure 9A The method for manufacturing a display device according to an embodiment may include preparing a display element layer (S100) and forming a light control layer (S200). The display element layer DP-ED (see...) can be... Figure 4 An optical control layer RCL is formed on the surface (see [reference]). Figure 4 ). Reference Figure 9BThe operation of forming the light control layer (S200) may include forming a first preliminary organic film (S210), forming a second preliminary organic film having a first region defined therein (S220), forming a light blocking member in the first region (S230), forming an organic film having a first region and a second region defined therein (S240), and forming an optical pattern in the second region (S250).

[0166] Reference Figure 10 A first preliminary organic film P1-TMA can be formed on the display module DM. The display module DM may include a display element layer DP-ED (see...). Figure 4 For example, a first preliminary organic film P1-TMA can be formed by depositing an organic material. For example, the first preliminary organic film P1-TMA may include at least one of a polyimide resin, an acyl resin, and a siloxane resin. However, this is presented by way of example, and embodiments of the inventive concept are not limited thereto.

[0167] Subsequently, as Figure 11 As shown, this can be achieved by processing the first preliminary organic membrane P1-TMA (see...). Figure 10 An etching process is performed to form a second preliminary organic film P2-TMA having a first region T-OH1 defined therein. The first preliminary organic film P1-TMA can be removed (see [link to original text]). Figure 10 A portion of the first preliminary organic membrane P1-TMA is used to form a second preliminary organic membrane P2-TMA having a first region T-OH1 defined therein. This can be achieved from the first preliminary organic membrane P1-TMA (see...). Figure 10 The second preliminary organic film P2-TMA is formed. For example, the first region T-OH1 can be formed by a dry etching process.

[0168] Reference Figure 11 A light-blocking component BMA can be formed in the first region T-OH1. A light-blocking component BMA filling the first region T-OH1 can be formed by providing a light-absorbing material within the first region T-OH1.

[0169] After forming the light-blocking component BMA, it can be as follows: Figure 12 The second region T-OH2 is formed as shown in the diagram. This can be achieved by processing the second preliminary organic membrane P2-TMA (see...). Figure 11 An etching process is performed to form an organic film TMA having a first region T-OH1 and a second region T-OH2 defined therein. The second preliminary organic film P2-TMA can be removed (see [link to documentation]). Figure 11 A portion of this is used to form an organic membrane TMA having a first region T-OH1 and a second region T-OH2 defined therein. It can be formed from a second preliminary organic membrane P2-TMA (see...). Figure 11Organic TMA film is formed. For example, the second region T-OH2 can be formed by a dry etching process.

[0170] In the method of manufacturing a display device according to an embodiment, the operation of forming the first region T-OH1 can be performed before the operation of forming the light-blocking component BMA, and the operation of forming the second region T-OH2 can be performed after the operation of forming the light-blocking component BMA. The first region T-OH1 and the second region T-OH2 can be formed by a dry etching process. Therefore, the first width W1 of the organic film TMA (see...) Figure 5 The second width W2 of the light-blocking component BMA can decrease as the organic film TMA is positioned further away from the display module DM, and the second width W2 of the light-blocking component BMA (see...) Figure 5 The light-blocking component (BMA) can increase as it is positioned further and further away from the display module (DM).

[0171] After the formation of the second region T-OH2, it can be as follows Figure 13 The optically patterned LRP shown is formed. For example, an optically patterned LRP can be formed by depositing at least one of a metal and an inorganic material. When forming Figure 6 When the optical pattern LRP-a shown is formed, it can be formed by photolithography to include only the first patterned portion L-P1 (see...). Figure 5 The optical pattern LRP-a (see) Figure 6 ).

[0172] After forming the optical pattern LRP, it can be like Figure 14 The diagram illustrates the formation of a transmission element VC. The transmission element VC can be formed by filling the remaining areas within the second region T-OH2, except for the area where the optical pattern LRP is formed. For example, the transmission element VC can be formed by coating the remaining areas with an organic material. However, this is presented as an example, and the method of forming the transmission element VC is not limited to this.

[0173] Figure 15 This is a block diagram illustrating an electronic device according to an embodiment.

[0174] Reference Figure 15 For example, according to an embodiment of the present invention, the electronic device 1000 can output various information (e.g., images, text, music, etc.) through a display module DM that can correspond to the display devices DD / DD-a / DD-b described above. When the processor 1110 executes an application stored in the memory 1120, the display module DM can provide application information to the user through the display panel DP.

[0175] In some embodiments, for example, electronic device 1000 may be configured as a smartphone, camera, smart TV, monitor, smartwatch, tablet computer, automotive display, or augmented reality / virtual reality (AR / VR) headset. For example, electronic device 1000 may be a smartphone including a touch-sensitive display area for interaction and a non-display area containing sensors and circuitry for enhanced functionality. For example, electronic device 1000 may be a TV or monitor including a large display area for high-resolution video playback and a non-display area containing driving circuitry or connection modules for external input. For example, electronic device 1000 may be a smartwatch including a display area optimized for compact and high-definition vision and a non-display area integrating biosensors for health monitoring. In some cases, electronic device 1000 is an AR / VR headset.

[0176] In some embodiments, memory 1120 may store information, such as software code for operating application 1123. Memory 1120 stores multiple applications 1123 for execution by processor 1110. Applications 1123 may include software designed to perform specific tasks or provide functionality to a user. Applications 1123 may operate under the control of processor 1110 and utilize data stored in memory 1120 to deliver a wide range of features, such as productivity tools, multimedia streaming and playback, file or mail delivery, or communication services. Applications 1123 interact seamlessly with user interface 1161 or touchscreen 1142, allowing users to launch, navigate, and utilize the program through user input such as touch, tap, gestures, or voice interaction.

[0177] When a user selects an application via touchscreen 1142 or user interface 1161, processor 1110 can execute application 1123 corresponding to the selected application, retrieved from memory 1120, to perform the functions of that application. User interface 1161 can be configured to sense user input via touch or cursor selection of an icon presented on display panel DP, and upon receiving user input, cause processor 1110 to execute one or more of a plurality of stored applications 1123. For example, when a user selects a camera application by tapping an icon (or camera application icon) presented on display panel DP, processor 1110 activates the camera module. Processor 1110 can send image data corresponding to a captured image acquired by the camera module to display module DM. Display module DM can display the image corresponding to the captured image via display panel DP.

[0178] In one embodiment, when a user wishes to make a call, the user taps a phone icon displayed in the display module DM, and the processor 1110 can execute a phone application stored in the memory 1120. A phone keypad can be presented to the user on the display panel DP to input the phone number to be called.

[0179] In this embodiment, the display module DM can be integrated into an electronic device 1000, such as a laptop computer, smart TV, or tablet computer. Users wishing to access multimedia streaming applications (e.g., watching music videos or movies) can do so by tapping the corresponding icon. This action activates the application, allowing the user to watch streaming content.

[0180] Processor 1110 may include a main processor 1111 and an auxiliary processor or coprocessor 1112. Main processor 1111 may include a central processing unit (CPU). Main processor 1111 may also include one or more of a graphics processing unit (GPU), a communication processor (CP), and an image signal processor (ISP).

[0181] The coprocessor 1112 may include a controller 1112-1. The controller 1112-1 may include interface conversion circuitry and timing control circuitry. The controller 1112-1 can receive image signals from the main processor 1111, convert the data format of the image signals to match the interface specifications of the display module DM, and output the image data. The controller 1112-1 can output various control signals to drive the display module DM. For example, the controller 1112-1 can drive the display module DM to display icons suitable for user selection on the display screen for the execution of application program 1123.

[0182] The memory 1120 may store one or more applications 1123 used by at least one component of the electronic device 1000 (e.g., processor 1110 or user interface 1161), as well as various data and command input or output data associated with the memory 1120. For example, camera applications, GPS applications, augmented reality and virtual reality applications, and other applications may be executed by the processor 1110 when the user selects a corresponding icon presented on the display screen (or display panel DP) via the touchscreen 1142 or user interface 1161. Furthermore, various setting data corresponding to user settings may be stored in the memory 1120. The memory 1120 may include volatile memory 1121 and non-volatile memory 1122.

[0183] The display module DM can output visual information (images) to the user. The display module DM may include a display panel DP, a gate driver, a source driver, a voltage generation circuit, and a touchscreen 1142. The display module DM may also include a window, a chassis, and a bracket to protect the display panel 100. The display module DM may include at least a portion of the configuration of the display devices DD / DD-a / DD-b described above.

[0184] User interface 1161 serves as an interaction medium between the user and electronic device 1000. User interface 1161 can detect input via a part of the user's body (e.g., a finger) or via a pen or mouse, and generate electrical signals or data values ​​corresponding to the input. User interface 1161 includes a fingerprint sensor 1162, an input sensor 1163, and a digitizer 1164.

[0185] The fingerprint sensor 1162 can sense a fingerprint used for a user's biometric identification and can also measure one or more biometric signals such as blood pressure, humidity, or weight.

[0186] For example, input sensor 1163 can sense user interactions including touch, tap, gesture, motion, verbal commands, and eye movement. Input sensor 1163 includes optical sensors for image capture, eye tracking, or motion and gesture detection. The optical sensors can be infrared or semiconductor photodetectors. Input sensor 1163 includes audio and acoustic sensors, which can be microelectromechanical systems (MEMS) microphones for speech recognition or voice-based interaction. The audio and acoustic sensors can be mounted as part of user interface 1161 or embedded in display panel DP.

[0187] The digitizer 1164 can generate data values ​​corresponding to coordinate information input via a pen or mouse to control the movement of the cursor on the screen. The digitizer 1164 can also generate data values ​​representing electromagnetic changes caused by the input. The digitizer 1164 can detect input via a passive pen, or send and receive data via an active pen or remote control.

[0188] At least one of the fingerprint sensor 1162, the input sensor 1163, and the digitizer 1164 can be implemented as a sensor layer formed on the top layer of the display panel DP by using a continuous process of forming elements (e.g., light-emitting elements and transistors) included in the display panel DP.

[0189] Furthermore, for example, the user interface 1161 may also include a gesture sensor, a gyroscope sensor for sensing rotational motion, an accelerometer sensor for tracking translational motion, a grip sensor, a pressure sensor, a proximity sensor, a color sensor, an infrared (IR) emitter and camera sensor for tracking gaze direction and eye movement, a temperature sensor, or a light sensor. For example, the gyroscope sensor, accelerometer sensor, and infrared emitter and camera sensor may be particularly suitable for AR / VR headset functionality.

[0190] Touchscreen 1142 includes a touch sensor embedded in a semiconductor layer of display panel DP to sense pressure applied to the top layer (screen) of display panel DP. The touch sensor can be capacitive or resistive. Touchscreen 1142 can serve as a main interface for user selection and navigation applications, control, and interaction with electronic device 1000.

[0191] For example, a display panel (DP) can include a liquid crystal display panel, an organic light-emitting display panel, or an inorganic light-emitting display panel. However, the type of display panel (DP) is not particularly limited. A display panel (DP) can be rigid or flexible, capable of being rolled up or folded. A display module (DM) can also include supports, brackets, and heat dissipation components that support the display panel (DP). The display panel (DP) can include at least a portion of the configuration of the display devices (DD / DD-a / DD-b) described above.

[0192] Power module 1150 can supply power to the components of electronic device 1000. Power module 1150 may include a battery that is charged to a power supply voltage. The battery may include a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell. Power module 1150 may include a power management integrated circuit (PMIC). The PMIC can supply optimized power to each of the components described above, including display module DM.

[0193] Figure 16 This is a schematic diagram illustrating an electronic device according to various embodiments. (Refer to...) Figure 16 The electronic devices including the display devices DD / DD-a / DD-b according to the embodiments can include not only electronic devices for displaying images, such as smartphones 10_1a, tablet PCs 10_1b, laptop computers 10_1c, TVs 10_1d, and monitors 10_1e for desktop computers, but also wearable electronic devices that include display devices, such as smart glasses 10_2a, head-mounted displays 10_2b, and smartwatches 10_2c, as well as vehicle electronic devices 10_3 that include display devices, such as vehicle instrument panels, central instrument clusters, central information displays (CIDs) mounted on the dashboard, and rearview mirror displays.

[0194] A method for manufacturing a display device according to an embodiment may include forming a light control layer on a display element layer. The method may include forming a first region and a second region before and after forming a light-blocking member. A transmissive member, wherein the first and second regions are spaced apart from each other in a direction perpendicular to the thickness direction, may be formed by performing an etching process on a preliminary organic film. The light-blocking member is formed to fill the first region, and then an optical pattern may be formed in the second region.

[0195] The display device manufactured according to the method of manufacturing a display device according to the embodiment may include a light control layer disposed on a display element layer. The light control layer may include an organic film having a first region and a second region defined therein, a light-blocking member configured to fill the first region, and an optical pattern disposed in the second region. A first width of the organic film may decrease as the organic film is disposed further away from the display element layer, and a second width of the light-blocking member may increase as the light-blocking member is disposed further away from the display element layer. The optical pattern may be disposed on the inner surface of the organic film defining the second region. In cross-section, the organic film, the light-blocking member, and the optical pattern may form a trapezoidal shape structure, and therefore, the light control layer according to the embodiment may include a trapezoidal shape structure, which can exhibit excellent light-blocking performance. Therefore, in the embodiment, the display device including the light control layer can exhibit excellent display quality.
