AI Technical Summary
In the bent sections of the display panel, the uneven brightness of the reflected image makes it difficult for users to see a clear image.
The substrate employs first and second display areas arranged on a substrate, each with a first and second refractive layer having a different tilt angle. By combining a hole area design with a tilted pixel electrode structure, the light refraction path is optimized to reduce brightness differences.
By optimizing the refractive layer and pixel electrode structure, the image clarity of the display panel under bending conditions has been improved, providing more uniform brightness and clearer image display.

[0123] For the purposes of this description, the embodiments will be illustrated in more detail below with reference to the accompanying drawings, in which the same reference numerals refer to the same elements throughout. However, this disclosure may be embodied in various different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art the aspects and features of this disclosure. Accordingly, processes, elements, and techniques that are not essential to a person of ordinary skill in the art for a full understanding of the aspects and features of this disclosure may not be described. Unless otherwise stated, the same reference numerals refer to the same elements throughout the accompanying drawings and written description, and therefore, redundant descriptions thereof will not be repeated.
[0124] When an embodiment can be implemented differently, the specific order of processing may differ from the order described. For example, two consecutively described processes may be executed simultaneously or substantially simultaneously, or they may be executed in the reverse order of the described order.
[0125] Furthermore, as those skilled in the art will understand, given the overall nature of this disclosure, each suitable feature of the various embodiments of this disclosure may be combined or integrated with each other in part or in whole, and may be technically interconnected and operated in various suitable ways, and each embodiment may be implemented independently of each other or in combination with each other in any suitable way, unless otherwise stated or implied.
[0126] In the accompanying drawings, for clarity, the relative dimensions, thicknesses, and proportions of elements, layers, and regions may be exaggerated and / or simplified. For ease of interpretation, spatially related terms such as “below,” “under,” “down,” “below,” “above,” and “on” are used herein to describe the relationship between one element or feature illustrated in the figures and another element (or feature) or feature (or feature). It will be understood that, in addition to the orientations depicted in the figures, spatially related terms are intended to cover different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below” or “under” or “below” other elements or features will subsequently be oriented “above” other elements or features. Thus, the terms “below” and “below” can encompass both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or otherwise), and the spatially related descriptors used herein should be interpreted accordingly.
[0127] Furthermore, it should be anticipated that the shapes shown in the figures may differ in practice depending on, for example, tolerances and / or manufacturing techniques. Accordingly, the embodiments of this disclosure should not be construed as limited to the specific shapes shown in the figures, and should be interpreted in light of variations in shape that may occur, for example, due to manufacturing processes. Thus, the shapes shown in the figures may not depict the actual shape of an area of the device, and this disclosure is not limited thereto.
[0128] In the diagram, the x-axis, y-axis, and z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular or substantially perpendicular to each other, or they can represent different directions that are not perpendicular to each other.
[0129] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or parts, these elements, components, areas, layers, and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, area, layer, or part from another element, component, area, layer, or part.

Furthermore, the first length L1, the second length L2, and the third length L3 can indicate the distance between the boundaries of each area.
[0168] The peripheral region PA may be a region that does not provide an image. The peripheral region PA may at least partially surround the display region DA (e.g., surround its perimeter). In an embodiment, the peripheral region PA may completely surround the display region DA (e.g., enclose its perimeter). Drivers or similar devices for providing electrical signals or power to the sub-pixel P may be arranged in the peripheral region PA. Furthermore, the peripheral region PA may include a pad region in which pads are arranged.

The planar shape of the corresponding first aperture region may be formed to be larger than the planar shape of the emitting region of the corresponding display element. For example, the first aperture region may expose at least a portion of the corresponding emitting region to the outside. In this case, the planar shape of the corresponding emitting region may be arranged inside the planar shape of the first aperture region. For example, the planar shape of the first-2 emission region EL1-2 can be arranged inside the planar shape of the first-2 aperture region SL-2A, the planar shape of the second-2 emission region EL2-2 can be arranged inside the planar shape of the second-2 aperture region SL-2B, and the planar shape of the third-2 emission region EL3-2 can be arranged inside the planar shape of the third-2 aperture region SL-2C.

[0222] Each of the display elements may include an emission region. For example, the first-3 display element OLED1-3 may include a first-3 emission region EL1-3, the second-3 display element OLED2-3 may include a second-3 emission region EL2-3, and the third-3 display element OLED3-3 may include a third-3 emission region EL3-3. This is because the first-3 emission region EL1-3, the second-3 emission region EL2-3, and the third-3 emission region EL3-3 can be respectively associated with the above reference. Figure 7A The first-1 emission region EL1-1, the second-1 emission region EL2-1, and the third-1 emission region EL3-1 are described as being the same or substantially the same (or similar), so their redundant descriptions will not be repeated below.

The edges of the planar shapes of the corresponding island layers may be spaced apart from the edges of the planar shapes of the second aperture region corresponding to the island layer and the edges of the planar shapes of the emitting regions corresponding to the island layer. In addition, the planar shapes of the island layers may be disposed inside the planar shapes of the emitting regions corresponding to the island layers and the planar shapes of the corresponding second aperture regions.

The first-3A hole region SL-3AA and the first-3 island layer BL1-3 may each have an annular planar shape. The planar shape of the first-3 island layer BL1-3 may be disposed inside the outermost edge of the planar shape of the first-3A hole region SL-3AA. Furthermore, the first-3B hole region SL-3AB may have an island-shaped planar shape.

Furthermore, the third-3-hole region SL-3C may include the third-3A hole region SL-3CA and the third-3B hole region SL-3CB. Because the second-3-hole regions SL-3B and the third-3-hole region SL-3C are similar to the first-3-hole region SL-3A described above, their redundant description will not be repeated below.
[0227] The total area of the first aperture region corresponding to a display element arranged in the first region DA-2B can be smaller than the total area of the second aperture region arranged in the second region DA-2C, which corresponds to a display region emitting light of the same color as a display element arranged in the first region DA-2B. For example... Figure 7B The total area of the planar shape of the first-2 hole region SL-2A shown can be less than Figure 7CThe total planar area of the first-3 hole region SL-3A shown is illustrated. The total planar area of the second-2 hole region SL-2B can be smaller than the total planar area of the second-3 hole region SL-3B. Furthermore, the total planar area of the third-2 hole region SL-2C can be smaller than the total planar area of the third-3 hole region SL-3C.
[0228] Furthermore, the total area of the planar shapes of the island layers in the display areas of the first and second regions, where display elements emitting light of the same color are respectively arranged, can be different from each other. For example, the total area of the planar shapes of the island layers arranged to correspond to the display area of the first region DA-2B can be greater than the total area of the planar shapes of the island layers arranged to correspond to the display area of the second region DA-2C. For example, Figure 7B The total area of the planar shape of the first-2 island layer BL1-2 shown can be greater than Figure 7C The total area of the planar shape of the first-3 island layer BL1-3 shown is greater than the total area of the planar shape of the second-2 island layer BL2-2. Furthermore, the total area of the planar shape of the third-2 island layer BL3-2 is greater than the total area of the planar shape of the third-3 island layer BL3-3.
[0229] By controlling the amount of refracted light through differences in area as described above, the brightness of the light emitted from the corresponding area and reflected from the beam splitter can be uniform or substantially uniform.

[0248] The dam layer 225 may cover the edge of the pixel electrode 221. The dam layer 225 may have an opening OP defined therein. The central portion of the pixel electrode 221 may be exposed through the opening OP. The opening OP may be defined as an emission region for light emitted from an organic light-emitting diode (OLED). In an embodiment, the width of the first-1 emission region EL1-1 in the first direction x may be greater than the width of the first-1 emission region EL1-1 in the second direction y. In an embodiment, the dam layer 225 may comprise organic and / or inorganic materials. In an embodiment, the dam layer 225 may be transparent. In some embodiments, the dam layer 225 may comprise a black matrix. In this case, the dam layer 225 may be opaque.
[0249] The intermediate layer 222 may include a first functional layer 222a, an emitting layer 222b, and a second functional layer 222c. The emitting layer 222b may include a polymer or a low molecular weight organic material that emits light of a desired color (e.g., a specific or predetermined color).
[0250] In embodiments, at least one of the first functional layer 222a and the second functional layer 222c may be a common layer integrally arranged over the display area. For example, the first functional layer 222a may include a hole transport layer (HTL), or may include an HTL and a hole injection layer (HIL). The second functional layer 222c may include an electron transport layer (ETL) and / or an electron injection layer (EIL). In some embodiments, the second functional layer 222c may be omitted as needed or desired.
[0251] A common electrode 223 may be disposed on the emitter layer 222b. The common electrode 223 may comprise a conductive material having a low work function. For example, the common electrode 223 may comprise a (semi-)transparent layer comprising Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, lithium (Li), Ca, and / or any suitable alloy thereof. In some embodiments, the common electrode 223 may further comprise a layer such as ITO, IZO, ZnO, AZO, and / or In2O3 on top of a (semi-)transparent layer comprising one or more of the materials described above.
[0252] In some embodiments, a capping layer may be further disposed on the common electrode 223. The capping layer may include lithium fluoride (LiF), inorganic materials, and / or organic materials.
[0253] The encapsulation layer 300 can be disposed on the display element layer 220. The encapsulation layer 300 can cover the first-1 display element OLED1-1, the first-2 display element OLED1-2, and the first-3 display element OLED1-3. In an embodiment, the encapsulation layer 300 may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. Figure 8 The encapsulation layer 300 is shown to include a first inorganic encapsulation layer 310, an organic encapsulation layer 320, and a second inorganic encapsulation layer 330 stacked in sequence.
[0254] At least one inorganic encapsulation layer may include Al2O3, TiO2, Ta2O5, HfO2, ZnO, SiO2, or SiN. x The inorganic encapsulation layer 310 may include one or more inorganic materials, such as SiON and / or SiN.

[0255] At least one organic encapsulation layer may comprise a polymeric material. The polymeric material may include acrylic resins, epoxy resins, polyimides, or polyethylene, etc. In an embodiment, at least one organic encapsulation layer may comprise an acrylate.
[0256] In this embodiment, the first refractive layer BL1 and the second refractive layer OL can be located in the first display area DA1 and the second display area DA2. The first refractive layer BL1 and the second refractive layer OL can be disposed on the encapsulation layer 300. The refractive indices of the first refractive layer BL1 and the second refractive layer OL can be different from each other.
[0257] The first refractive index of the first refractive layer BL1 can be in the range of about 1.3 to about 1.6. In embodiments, the first refractive index of the first refractive layer BL1 can be in the range of about 1.4 to about 1.55. For example, the first refractive layer BL1 may include ethylhexyl acrylate, pentafluoropropyl acrylate, polyethylene glycol dimethacrylate, and / or ethylene glycol dimethacrylate, etc. In embodiments, the first refractive layer BL1 may include an acrylic organic material having a refractive index of about 1.5. Furthermore, the first refractive layer BL1 may include a suitable material for forming the organic encapsulation layer 320 of the encapsulation layer 300. In embodiments, the first refractive layer BL1 may include an epoxy organic material, and in some cases, may also include a photocurable material.
[0258] The second refractive layer OL can be a planarization layer having a second refractive index. The second refractive index of the second refractive layer OL can be in the range of about 1.65 to about 1.85. For example, the second refractive layer OL can include polydiarylsiloxane, methyltrimethoxysilane, and / or tetramethoxysilane, etc. In embodiments, the second refractive layer OL can include acrylic organic materials and / or siloxane organic materials having a refractive index of about 1.6. In another embodiment, the second refractive layer OL can include dispersed particles for a high refractive index. For example, zinc oxide (ZnO) can be dispersed in the second refractive layer OL. x Metal oxide particles of TiO2, zirconium dioxide (ZrO2) and / or barium titanate (BaTiO3).
[0259] In this case, the first refractive layer BL1 and the second refractive layer OL can be arranged in multiple display regions in the respective regions with the same or substantially the same (or similar) shapes. For ease of explanation, the following will describe in more detail the case where the first refractive layer BL1 and the second refractive layer OL are arranged on the first-1 display element OLED1-1 arranged in the connecting region DA-2A, the first-2 display element OLED1-2 arranged in the first region DA-2B, and the first-3 display element OLED1-3 arranged in the second region DA-2C.
[0260] The first refractive layer BL1 can be disposed over the entire upper surface of the display element in the connection region DA-2A, and may not have an aperture region. For example, the first refractive layer BL1 can be disposed to completely shield the upper surface of the first-1 display element OLED1-1.
[0261] As described above, the first refractive layer BL1 disposed in the first region DA-2B and the second region DA-2C may include island layers, a first aperture region, and a second aperture region. For example, the first-2 island layer BL1-2 and the first-2 aperture region SL-2A may be provided in the portion of the first refractive layer BL1 corresponding to the first-2 emission region EL1-2. The first refractive layer BL1 and the first-2 island layer BL1-2 disposed around the first-2 aperture region SL-2A may have a first-2 inclined surface BL1-2A in which the first-2 aperture region SL-2A is defined. Furthermore, the first-3 island layer BL1-3 and the first-3 aperture region SL-3A may be disposed in the portion of the first refractive layer BL1 corresponding to the first-3 emission region EL1-3. The first-3A aperture region SL-3AA may be defined on the outer side of the first-3 island layer BL1-3, and the first-3B aperture region SL-3AB may be disposed on the inner side of the first-3 island layer BL1-3. In this case, the first refractive layer BL1 and the first island layer BL1-3 arranged around the first-3 hole region SL-3A can have a first-3 inclined surface BL1-3A.
[0262] In this case, the first-2 tilt angle θ1-1 of the first-2 tilted surface BL1-2A and the first-3 tilt angle θ2-1 of the first-3 tilted surface BL1-3A can be different from each other. For example, the first-2 tilt angle θ1-1 can be smaller than the first-3 tilt angle θ2-1.
[0263] In this configuration, light emitted from the first-2 display element OLED1-2 can travel in a straight line or substantially in a straight line. Due to the difference in refractive index between the first-2 tilted surface BL1-2A and the first refractive layer BL1 and the second refractive layer OL, at least some of the light emitted from the first-2 display element OLED1-2 can be altered, such that the light path has a first-2 refraction angle θ1-2. Furthermore, due to the difference in refractive index between the first-3 tilted surface BL1-3A and the first refractive layer BL1 and the second refractive layer OL, at least some of the light emitted from the first-3 display element OLED1-3 can be altered, such that the light path has a first-3 refraction angle θ2-2. Each of these refraction angles can indicate the angle between the straight-line path of light and the direction of light travel on the altered path. In this configuration, the first-2 refraction angle θ1-2 can be smaller than the first-3 refraction angle θ2-2.
[0264] When the first region DA-2B and the second region DA-2C do not include the aperture region, light emitted from the display elements arranged in the first region DA-2B and the second region DA-2C can travel in a straight line or substantially in a straight line, and due to the tilt of the reflective surface of the beam splitter, some of the light emitted from the display elements arranged in the first region DA-2B and the second region DA-2C may not be delivered to the user. However, by arranging islands and aperture regions in the first region DA-2B and the second region DA-2C as described above, the path of at least some of the light emitted from the display elements arranged in the first region DA-2B and the second region DA-2C can be altered, thereby increasing the area in which the light emitted from the display elements arranged in the first region DA-2B and the second region DA-2C can be reflected by the beam splitter. For example, by refracting light emitted from the sides of display elements arranged in the first region DA-2B and the second region DA-2C, some of the light emitted from the display elements arranged in the first region DA-2B and the second region DA-2C can be transmitted as close as possible to the area of the beam splitter where light emitted from the connecting region DA-2A is reflected. Furthermore, by changing the refraction angle of at least some of the light emitted from the first region DA-2B, and allowing the refraction angle of the light emitted from the second region DA-2C to be greater than that of the light emitted from the first region DA-2B, the brightness of the light emitted from the connecting region DA-2A, the first region DA-2B, and the second region DA-2C can become nearly similar or uniform. In this case, when the image realized in the second display region DA2 is reflected from the beam splitter and viewed by the user, the user can hardly perceive any difference in brightness in the image realized in the second display region DA2.
[0265] Figure 9A and Figure 9B It is a schematic map showing the manufacturing process. Figure 8 A cross-sectional view showing the sequence of methods for displaying the panel.
[0266] refer to Figure 9A and Figure 9B The pixel circuit layer 210, display element layer 220, and encapsulation layer 300 can be arranged on the substrate 100, and then the first refractive layer BL1 can be arranged on the encapsulation layer 300. The pixel circuit layer 210, display element layer 220, and encapsulation layer 300 can be related to the above-mentioned reference. Figure 8 Those described are the same or substantially the same (or similar), and therefore, redundant descriptions of them need not be repeated below. Furthermore, Figure 9A and Figure 9B and Figure 8The same reference numerals used in the figures above indicate the same references. Figure 8 The elements or components described are the same or substantially the same.
[0267] When the first refractive layer BL1 is arranged, a first photoresist PR1 can be coated on the first refractive layer BL1, and a pattern can be formed thereon. The pattern of the first photoresist PR1 can be arranged only in the portion corresponding to the first region DA-2B, and the connecting region DA-2A and the second region DA-2C can be completely shielded. Subsequently, the first refractive layer BL1 can be etched to form hole regions and island layers in the first region DA-2B. Furthermore, at least one of the first refractive layer BL1 and the island layers corresponding to the hole regions arranged in the first region DA-2B can be formed as described above. Figure 8 The first-2 inclined surfaces BL1-2A described are the same or substantially the same (or similar) inclined surfaces. For etching, dry etching using lasers or plasma gases, or wet etching using etchants, can be employed.
[0268] Once the process described above is completed, the first photoresist PR1 can be removed, and the second photoresist PR2 can be coated, such as... Figure 9B As shown in the diagram. Subsequently, the second photoresist PR2 can be exposed and developed to form a pattern in the second region DA-2C. Furthermore, the first refractive layer BL1 disposed in the second region DA-2C can be etched according to the pattern of the second photoresist PR2. At least one of the first refractive layer BL1 corresponding to the hole region disposed in the second region DA-2C and the island layer can be formed as described above. Figure 8 The first-3 inclined surfaces BL1-3A described are the same or substantially the same (or similar) inclined surfaces. For etching, dry etching using lasers or plasma gases, or wet etching using etchants, can be employed. In this case, by changing the etchant, etching method, and / or etching process conditions in the etching method used to form the hole regions and islands in the first region DA-2B, the tilt angles of the inclined surfaces arranged in the first region DA-2B and the inclined surfaces arranged in the second region DA-2C can be different from each other. By arranging the second photoresist PR2 to completely shield the connecting regions DA-2A and the first region DA-2B, the islands and hole regions formed in the first region DA-2B can be preserved.
[0269] Once the process described above is completed, the second photoresist PR2 can be removed, and the second refractive layer OL can be deposited on the first refractive layer BL1 by inkjet printing. In this case, the second refractive layer OL can be coated on the inside of the hole region formed in the first refractive layer BL1 and on the first refractive layer BL1.
[0270] Figure 10A and Figure 10B This is a schematic diagram illustrating a plan view of the first-3 emission region EL1-3 of the first-3 display element OLED1-3 and the first refractive layer arranged in the second region DA-2C of the display panel according to some embodiments.
[0271] refer to Figure 10A The first-3 emitting region EL1-3 of the first-3 display element OLED1-3 can be arranged to overlap with the first-3 aperture region SL-3A. In a plan view, the first-3 aperture region SL-3A may include a first-3A aperture region SL-3AA in which the first-3 emitting region EL1-3 is disposed, and a first-3B aperture region SL-3AB disposed in the first-3 emitting region EL1-3. In a plan view, the first-3 island layer BL1-3 can be disposed inside the first-3 emitting region EL1-3. Furthermore, the first-3B aperture region SL-3AB can be disposed in the first-3 island layer BL1-3. Multiple first-3B aperture regions SL-3AB can be provided, and the multiple first-3B aperture regions SL-3AB can be spaced apart from each other. At least a portion of the first-3 island layer BL1-3 can be formed in a grid shape.
[0272] In this configuration, at least some of the first refractive layer BL1 and the first-3 island layers BL1-3 arranged around the first-3 aperture region SL-3A may include inclined surfaces. These inclined surfaces may have a shape similar to... Figure 8 The inclined surfaces shown are of the same or substantially the same (or similar) shape.
[0273] In some embodiments, the first refractive layer BL1 disposed on the display element disposed in the second region DA-2C can be formed as similar to Figure 10A The structure shown.
[0274] refer to Figure 10B The first-3 aperture region SL-3A can be formed in a manner similar to the above reference. Figure 10AThe first-3A aperture region SL-3AA is described. Multiple first-3 island layers BL1-3 can be provided, and these multiple first-3 island layers BL1-3 can be spaced apart from each other. The multiple first-3 island layers BL1-3 can be arranged to overlap with the first-3 emission region EL1-3. In this case, light emitted from the first-3 display element OLED1-3 can be refracted in multiple regions.
[0275] At least a portion of the first-3 aperture region SL-3A can form a lattice shape. Furthermore, at least some of the first refractive layer BL1 and the first-3 island layers BL1-3 arranged around the first-3 aperture region SL-3A can include inclined surfaces. These inclined surfaces can have a shape similar to... Figure 8 The inclined surfaces shown are of the same or substantially the same (or similar) shape.
[0276] In some embodiments, the first refractive layer BL1 disposed on the display element disposed in the second region DA-2C can be formed as similar to Figure 10B The structure shown.
[0277] exist Figure 10A and Figure 10B In the structure shown, the total planar area of the aperture regions arranged in the first region DA-2B and corresponding to the display elements arranged in the first region DA-2B can be smaller than the total planar area of the aperture regions corresponding to the display elements arranged in the second region DA-2C, which emits light of the same color as the display elements arranged in the first region DA-2B. The total area can indicate the sum of the planar shapes of all aperture regions corresponding to a single display element. Furthermore, the total planar area of the island layers arranged in the first region DA-2B and corresponding to the display elements arranged in the first region DA-2B can be larger than the total planar area of the island layers corresponding to the display elements arranged in the second region DA-2C, which emits light of the same color as the display elements arranged in the first region DA-2B. The total area can indicate the sum of the planar shapes of all island layers corresponding to a single display element. For example, the number of island layers arranged in the first region DA-2B and corresponding to display elements emitting the same color of light as each other can be less than... Figure 10A The number of first-3B aperture regions SL-3AB shown. Furthermore, the island layers arranged in the first region DA-2B and corresponding to the display elements emitting light of the same color can have a greater... Figure 10B The first-3 island layers BL1-3 shown have a large area but fewer in number. For example, the island layers arranged in the first region DA-2B can have a larger area. Figure 10B The shape shown is formed by the four adjacent outer edges of the first-3 island layer BL1-3 being connected to each other.
[0278] Figure 11 This is a schematic diagram showing a cross-sectional view of a portion of the display panel according to an embodiment. Figure 12 It is a schematic map showing the arrangement in Figure 11 The diagram shows a plan view of the emission area and wiring locations in the second region DA-2C of the display panel. Figure 11 In the diagram, lines A-A', B-B', and C-C' represent cross-sections of the first emission region (e.g., first-1 emission region EL1-1), the second emission region (e.g., first-2 emission region EL1-2), and the third emission region (e.g., first-3 emission region EL1-3), similar to the reference above. Figure 8 Those described.
[0279] refer to Figure 11 and Figure 12 The display panel 10 may include a substrate 100, a display layer 200, an encapsulation layer 300, a first refractive layer BL1, and a second refractive layer OL.
[0280] Display layer 200 can be disposed on substrate 100. Display layer 200 may include pixel circuit layer 210 and display element layer 220. Pixel circuit layer 210 may include buffer layer 211, first gate insulating layer 213, second gate insulating layer 215, interlayer insulating layer 217, organic insulating layer 219, and pixel circuit PC. Pixel circuit PC may include thin film transistor (TFT) and storage capacitor Cst. Thin film transistor (TFT) may include semiconductor layer Act, gate electrode GE, source electrode SE, and drain electrode DE. Display element layer 220 may be disposed on pixel circuit layer 210. Display element layer 220 may be disposed on organic insulating layer 219. Display element layer 220 may include multiple organic light-emitting diodes (OLEDs), which are multiple display elements. In an embodiment, display element layer 220 may further include dam layer 225. Substrate 100, display layer 200, encapsulation layer 300, first refractive layer BL1 and second refractive layer OL can be referenced above. Figure 8 Those that are the same or substantially the same (or similar) as those described, and therefore, redundant descriptions of them need not be repeated, and can be described in more detail below. Figure 8 Those differences.
[0281] The display panel 10 may further include an additional organic insulating layer 218 between the interlayer insulating layer 217 and the organic insulating layer 219. The additional organic insulating layer 218 may include a material that is the same as or substantially the same as (or similar to) the material of the organic insulating layer 219. Furthermore, the pixel electrode 221 may be connected to the drain electrode DE via a separate connection electrode.
[0282] The display panel 10 may include wiring DUs in a layer in which connection electrodes are disposed. The wiring DUs may be disposed between the organic insulating layer 219 and an additional organic insulating layer 218. In another embodiment, as in... Figure 8 In the structure shown, the wiring DU can be arranged between the organic insulating layer 219 and the interlayer insulating layer 217.
[0283] A wiring DU can include a variety of appropriate wiring. For example, a wiring DU can be wiring that transmits voltage or various signals (such as data lines, scan lines, common voltage lines, drive voltage lines, or initialization voltage lines) when the display elements are operated.
[0284] The wiring DU can be provided as multiple lines, and at least some of the multiple wiring DUs can be arranged to overlap with the pixel electrodes of the display element.
[0285] refer to Figure 11 and Figure 12 The second width L3-3 of the plurality of wirings DU overlapping with the pixel electrode 221 of the first-1 display element OLED1-1 can be equal to or substantially equal to each other. On the other hand, the width of at least a portion of one of the plurality of wirings DU overlapping with the pixel electrode of the first-2 display element OLED1-2 can be different from the width of at least a portion of another of the plurality of wirings DU overlapping with the pixel electrode of the first-2 display element OLED1-2. Furthermore, the width of at least a portion of one of the plurality of wirings DU overlapping with the pixel electrode of the first-3 display element OLED1-3 can be different from the width of at least a portion of another of the plurality of wirings DU overlapping with the pixel electrode of the first-3 display element OLED1-3. In this case, the plurality of wirings DU overlapping with the first-2 display element OLED1-2 and the plurality of wirings DU overlapping with the first-3 display element OLED1-3 can have similar trends to each other. Accordingly, for ease of explanation, the plurality of wirings DU overlapping with the first-3 display element OLED1-3 can be described in more detail below.
[0286] refer to Figure 11 and Figure 12Some of the multiple wiring DUs can be arranged to pass through (e.g., extend across) the first-3 emission region EL1-3. The second width L3-3 of the multiple wiring DUs passing through the first-3 emission region EL1-3 can be the same or substantially the same as each other. Furthermore, at least one of the multiple wiring DUs passing through the first-3 emission region EL1-3 of the first-3 display element OLED1-3 may include a first protrusion DU-1 projecting towards the first-3 emission region EL1-3. The widths L3-1 and L3-2 of the portions of the wiring DU where the first protrusion DU-1 is formed can be greater than the second width L3-3 of the other portion of the wiring DU. For example, as... Figure 12 As shown in the figure, the first width L3-1 of the portion of the wiring DU in which the first protrusion DU-1 is formed can be greater than the second width L3-3 of the portion of the wiring DU in which the first protrusion DU-1 is not formed.
[0287] When at least two of the multiple wirings DU passing through the first-3 emission area EL1-3 have a first protrusion DU-1, the widths of the first protrusions DU1 may be equal or substantially equal to each other, or may be different from each other. For example, as Figure 12 As shown in the diagram, the third width L3-2 of the first protrusion DU-1 of the wiring DU located at the center can be smaller than the first width L3-1 of the first protrusion DU of the wiring DU located on the right side. In this case, Figure 12 It can be placed on a layer on the wiring DU (e.g., Figure 11 The upper surface of the organic insulating layer 219) forms a slope facing left. For example, the slope can be formed with its right side higher and its left side lower, such as... Figure 12 As shown in the example. Figure 12 The right side can be relatively closer Figure 3A The user UR shown in the figure, and Figure 12 The left side can be relatively closer to the first region DA-2B. The structure described above can also be applied to display elements arranged in the first region DA-2B. In this case, the protrusion of the wiring DU arranged in the first region DA-2B can be formed to be the same as or substantially the same as the first protrusion DU-1 arranged in the second region DA-2C, or it can be formed to have a width smaller than the width of the first protrusion DU-1 arranged in the second region DA-2C. In the structure described above, the upper surface of at least a portion of the layer arranged on the wiring DU can be formed to be inclined, or the layer arranged on the wiring DU can be formed to be inclined in one direction. The direction of inclination can be the same as or substantially the same as (or similar to) the direction described above. For ease of explanation, the case in which the slope is arranged only in a portion of the layer arranged on the wiring DU is described in more detail below.
[0288] As described above, by forming at least a portion of the pixel electrode 221 tilted by a protrusion (such as a first protrusion DU-1), and by tilting at least a portion of the intermediate layer 222 and the common electrode 223 sequentially stacked on the pixel electrode 221, light emitted from the first-3 display element OLED1-3 can be transmitted relative to the upper surface of the substrate 100 at a desired angle (e.g., a specific or predetermined angle).
[0289] In this case, in some embodiments, when the wiring DU arranged in the first region DA-2B does not include the protrusion, the first refractive layer BL1 arranged in the first region DA-2B can be arranged on the entire surface of the first region DA-2B, similar to the first refractive layer BL1 arranged in the connection region DA-2A.
[0290] As described above, the wiring DU may not include protrusions. For example, the width of one wiring passing through the display element may differ from the width of another wiring passing through the display element. In this case, the width of each wiring may decrease as the distance from the connection area DA-2A decreases, and may increase as the distance from the connection area DA-2A increases.
[0291] As described above, the ramps arranged in the display element can be formed in the pixel electrodes of the display element arranged in the first region DA-2B and the second region DA-2C. For example, the pixel electrodes of the display element arranged in the first region DA-2B can have a slightly flat shape by not overlapping with the wiring DU or by making the wiring DU without protrusions. On the other hand, the pixel electrodes of the display element arranged in the second region DA-2C can have ramps by overlapping with the wiring DU and by making the wiring DU have protrusions. In another embodiment, both the pixel electrodes of the display element arranged in the first region DA-2B and the pixel electrodes of the display element arranged in the second region DA-2C can have ramps. For example, as Figure 11 As shown, the pixel electrodes of the first-2 display element OLED1-2 arranged in the first region DA-2B and the pixel electrodes of the first-3 display element OLED1-3 arranged in the second region DA-2C can both have slopes. In this case, the slope of the pixel electrode of the first-2 display element OLED1-2 can be gentler than the slope of the pixel electrode of the first-3 display element OLED1-3. This relationship can be applied to all display elements arranged in the first region DA-2B and the second region DA-2C respectively and emitting light of the same color as each other. In this way, island layers and aperture regions can be obtained.
[0292] Figure 13This is a schematic map showing a portion of the display panel according to an embodiment.
[0293] refer to Figure 13 The multiple wiring DUs arranged in the second region may include protrusions. In this case, the wiring DUs that pass through the emission area of the same display element can be arranged symmetrically or substantially symmetrically with respect to the center of the emission area.
[0294] One of the wiring DUs passing through the first-3 emitting region EL1-3 of the first-3 display element OLED1-3 may include a first protrusion DU-1. In this case, the first protrusion DU-1 may protrude to the right of the wiring DU, such that at least a portion of the right side portion of the pixel electrode corresponding to the first-3 emitting region EL1-3 can be arranged at a higher position than the left side portion. In an embodiment, the first protrusion DU-1 may protrude in a direction different from the longitudinal direction of one of the wiring DUs.
[0295] One of the wiring DUs passing through the second-3 emitting region EL2-3 of the second-3 display element OLED2-3 may include a second protrusion DU-2. The second protrusion DU-2 may protrude to the left of the wiring DU. The second protrusion DU-2 may be formed in a "T" shape and may be connected to the wiring DU. In this case, the second protrusion DU-2 may be provided such that at least a portion of the pixel electrode corresponding to the second-3 light-emitting region EL2-3 that overlaps with the second protrusion DU-2 may be higher than the portion of the pixel electrode that does not overlap with the second protrusion DU-2. In some embodiments, the second protrusion DU-2 may connect two adjacent wiring DUs to each other.
[0296] One of the wiring DUs passing through the third emission region EL3-3 of the third-3 display element OLED3-3 may include a third protrusion DU-3. In this case, the third protrusion DU-3 may protrude to the right of the wiring DU, such that at least a portion of the right side of the pixel electrode corresponding to the third emission region EL3-3 may be higher than the left side.
[0297] With the structure described above, the pixel electrodes, intermediate layer and common electrode of the display element arranged in the second region DA-2C can be arranged in the inclined portion, so that the display element can emit light in such a way that at least some of these lights form a desired angle (e.g., a specific or predetermined angle) relative to a surface of the substrate 100.
