[0014] FIGS. 1 to 3 illustrate the condition of a display panel damaged by an external impact.
[0015] Referring to FIG. 1, a display panel (100) may be described as a device used for displaying information. The display panel (100) may be included within an electronic device. The electronic device may include a display driving circuit configured to control the display panel (100) to display information through the display panel (100), and a display (or display device) including the display panel (100). The electronic device may include at least one processor (e.g., including a processing circuit) configured to acquire an image containing the information and provide the image to the display driving circuit. The display driving circuit may acquire the image from the at least one processor and display the acquired image through the display panel (100) to display the information on the display panel (100). The form factor of the electronic device may vary. For example, the electronic device may be a bar-type electronic device. For example, the electronic device may be a foldable-type (or single-foldable-type) electronic device. For example, the electronic device may be a multi-foldable type electronic device. For example, the electronic device may be a rollable type or a sliderable type electronic device. A display panel (100) within the electronic device may define the front side (or top side) of the electronic device.
[0016] The display panel (100) may include a plurality of layers.
[0017] A display panel (100) may include a light-emitting layer (110). The light-emitting layer (110) may include light-emitting portions (115) and an insulating portion (114) that defines the periphery of each of the light-emitting portions (115) of the light-emitting layer (110). The insulating portion (114) may be described as a pixel definition layer (PDL) in that it functions to define a pixel (or subpixel). The insulating portion (114) may be described as an isolation portion (or electrical isolation portion).
[0018] The light-emitting portions (115) may each include light-emitting elements. For example, the light-emitting elements may include light-emitting diodes (LEDs). The LEDs may include organic LEDs (OLEDs). The light-emitting layer (110) may include an anode electrode portion (111) of an LED, a portion (112) containing a light-emitting material (or organic light-emitting material), and a cathode electrode portion (113) of an LED. The light-emitting portions (115) may be defined in a part of the light-emitting layer (110) where the anode electrode portion (111), the portion (112), and the cathode electrode portion (113) overlap each other.
[0019] A display panel (100) may include a sealing layer (120) placed over a light-emitting layer (110). The sealing layer (120) may be included within the display panel (100) to protect the light-emitting layer (110) from foreign substances (e.g., moisture and / or air) directed toward the light-emitting layer (110). The sealing layer (120) may seal the light-emitting layer (110).
[0020] As a non-limiting example, the encapsulation layer (120) may include a first inorganic layer (121) covering the cathode electrode portion (113) of the light-emitting layer (110). The encapsulation layer (120) may include a second inorganic layer (123) disposed on the first inorganic layer (121) of the encapsulation layer (120). The encapsulation layer (120) may include an organic layer (122) embedded between the first inorganic layer (121) and the second inorganic layer (123). The organic layer (122) may spatially separate the first inorganic layer (121) and the second inorganic layer (123). For example, an organic layer (122) may be embedded between the first inorganic layer (121) and the second inorganic layer (123) to reduce the insertion of foreign matter into the light-emitting layer (110) through pinholes that may occur within the first inorganic layer (121) and / or the second inorganic layer (123).
[0021] A display panel (100) may include a touch-sensitive layer (130) disposed on top of an encapsulation layer (120). The touch-sensitive layer (130) may include display panel electrodes (134). In an example that is not limited to, the touch-sensitive layer (130) may be used to identify input received in relation to the display panel (100) based on changes in capacitive coupling between the electrodes (134) and / or changes in capacitive coupling between each of the electrodes (134) and an external object (e.g., a finger or stylus placed on or over the display panel (100)). The touch-sensitive layer (130) may be described as a touch screen panel (TSP).
[0022] The touch-sensitive layer (130) may include an inorganic flattening layer (131). The inorganic flattening layer (131) may be included within the display panel (100) to flatten a portion of the display panel (100) on which electrodes (134) are to be placed. As an example without limitation, the inorganic flattening layer (131) may be described as a passivation layer.
[0023] First electrodes (134-1), which are a first part of the electrodes (134), may be placed on an inorganic flattening layer (131). The first electrodes (134-1) may extend in a first direction (e.g., the direction of the x-axis or the direction of the y-axis) and be arranged parallel in a second direction (e.g., the direction of the y-axis or the direction of the x-axis) which is (substantially) perpendicular to the first direction.
[0024] The touch-sensitive layer (130) may include an inorganic insulating layer (132). The inorganic insulating layer (132) may be placed on the inorganic flattening layer (131) to cover the first electrodes (134-1).
[0025] The second electrodes (134-2), which are a second part of the electrodes (134), may be disposed on an inorganic insulating layer (132). The second electrodes (134-2) may extend in the second direction and be arranged parallel to the first direction. The inorganic insulating layer (132) may be disposed between the first part and the second part of the electrodes (134). For example, the inorganic insulating layer (132) may be disposed between the first electrodes (134-1) and the second electrodes (134-2) for variations in capacitive coupling between a part of the first electrodes (134-1) and a part of the second electrodes (134-2).
[0026] The touch-sensitive layer (130) may include an inorganic protective layer (133) for protecting the electrodes (134) (or the touch-sensitive layer (130)). The inorganic protective layer (133) may be placed over the inorganic insulating layer (132) to cover the second electrodes (134-2).
[0027] The touch-sensitive layer (130) may include a stepped portion (135) at the portion where the electrodes (134) are located. The stepped portion (135) may be described as a portion including a first horizontal portion, a vertical portion extending from the first horizontal portion, and a second horizontal portion extending from the vertical portion.
[0028] A display panel (100) may include a color filter layer (140) placed on top of a touch-sensitive layer (130). The color filter layer (140) may be included within the display panel (100) for visual quality (e.g., visual quality of information displayed through the display panel (100)) that is not reduced or is relatively less reduced depending on external light (e.g., sunlight) reaching the display panel (100). The color filter layer (140) may include color filter portions (141) each aligned with the light-emitting portions (115) of the light-emitting layer (110), and a black matrix (BM) portion (142) defining the edges of each of the color filter portions (141) of the color filter layer (140). The BM portion (142) may be described as an opaque portion. The BM portion (142) may be described as a light-blocking portion. As a non-limiting example, the BM portion (142) may be defined by overlapping a first color filter portion configured to pass red light, a second color filter portion configured to pass blue light, and a third color filter portion configured to pass green light. For example, the BM portion (142) may be implemented by the first color filter portion placed on the second color filter portion and the third color filter portion placed on the first color filter portion.
[0029] The color filter portions (141) of the color filter layer (140) may each overlap with the light-emitting portions (115) of the light-emitting layer (110). Each of the color filter portions (141) of the color filter layer (140) may be configured to allow light of a color corresponding to the color of light emitted from the light-emitting portions (115) of the light-emitting layer (110) (e.g., red, blue, or green) to pass through, and to disallow light of a color that does not correspond to (or is different from) the color of light emitted from the light-emitting portions (115) of the light-emitting layer (110).
[0030] The display panel (100) may include a layer (150) placed on top of a color filter layer (140). The layer (150) may be placed on top of the color filter layer (140) to flatten the display panel (100). The layer (150) may be described as an overcoating layer.
[0031] Since the display panel (100) defines the front side of the electronic device, an external impact may be applied to the display panel (100). For example, the state (191) of the display panel (100) may be described as a state in which an external impact is applied to the display panel (100), as indicated by the indication (193).
[0032] The display panel (100) may be damaged by an external impact. For example, the state (192) of the display panel (100) may be described as the state of the display panel (100) damaged by an external impact.
[0033] As described above, the touch-sensitive layer (130) may include a stepped portion (135) formed by including electrodes (134). The stepped portion (135) may be fractured more easily than a planar portion (not shown). For example, fracture (194) of the display panel (100) may occur from the stepped portion (135) depending on an external impact, such as in state (192).
[0034] A layer of the display panel (100) formed from an inorganic material is superior to a layer of the display panel (100) formed from an organic material in terms of blocking foreign substances, but a layer of the display panel (100) formed from an inorganic material can be more fragile than a layer of the display panel (100) formed from an organic material. As a non-limiting example, since the layers within the touch-sensitive layer (130) are formed from an inorganic material, the crack (194) of the display panel (100) can extend to the encapsulation layer (120). For example, foreign substances (e.g., oxygen or moisture) can be inserted into the light-emitting layer (110) through the crack in the encapsulation layer (120). Foreign substances inserted into the light-emitting layer (110) can oxidize a portion (112) of the light-emitting layer (110) (e.g., containing organic material). Oxidation of the portion (112) of the light-emitting layer (110) can reduce the light-emitting properties. For example, due to oxidation of a portion (112) of the light-emitting layer (110), a black spot may occur within the displayable portion (or active portion) (or active area) (or display portion) of the display panel (100). Such a black spot may reduce the quality of the display panel (100).
[0035] Referring to FIG. 2, the electronic device described with reference to FIG. 1 may include a structure (280) that supports a display panel (100) and / or is positioned below the display panel (100). The structure (280) may be described as a bracket of the electronic device.
[0036] The display panel (100) may include a portion (290) (or rear portion (290)) (or bottom portion (290)) that is closer to the rear side (or bottom side) of the display panel (100) than to the front side (or top side) of the display panel (100).
[0037] A portion (290) of the display panel (100) may include a substrate layer (260). The substrate layer (260) may be formed from polyimide. The substrate layer (260) may be flexible or deformable.
[0038] A portion (290) of the display panel (100) may include a buffer layer (265) formed on a substrate layer (260). The buffer layer (265) may be placed on the substrate layer (260). The buffer layer (265) may be included in the display panel (100) to reduce the movement of material (or foreign material) that may occur between the substrate layer (260) and the circuit layer (270) when forming the circuit layer (270) described below (e.g., an active layer (not shown in FIG. 2) within the circuit layer (270) (e.g., formed from LTPS (low-temperature polycrystalline silicon) or LTPO (low-temperature polycrystalline oxide)). The buffer layer (265) may be described as being included within the substrate layer (260) or the circuit layer (270).
[0039] A portion (290) of the display panel (100) may include a circuit layer (270). The circuit layer (270) may be formed on a substrate layer (260) or a buffer layer (265). The circuit layer (270) may be placed on the substrate layer (260) or the buffer layer (265). The circuit layer (270) may be placed below a light-emitting layer (110). The circuit layer (270) may include transistors configured to control light emission from each of the light-emitting portions (115). The transistors may be described as light-emitting driving circuitry or light-emitting driving circuits. The circuit layer (270) may further include a gate driver circuit.
[0040] The circuit layer (270) may include the active layer. The circuit layer (270) may include one or more inorganic insulating layers and / or one or more organic insulating layers.
[0041] The display panel (100) can be supported by a structure (280). The structure (280) placed below the display panel (100) may include one or more groove portions (281).
[0042] Since the display panel (100) defines the front side of the electronic device, an external impact may be applied to the display panel (100). For example, the state (191) of the display panel (100) may be described as a state in which an external impact is applied to the display panel (100), as indicated by the indication (193).
[0043] The display panel (100) may be deformed at least partially depending on an external impact. For example, a part (290) of the display panel (100) may be bent depending on an external impact, such as an indication (294). For example, the state (292) of the display panel (100) may be described as a state in which the part (290) of the display panel (100) is bent due to an external impact.
[0044] A layer of the display panel (100) formed from an inorganic material is superior to a layer of the display panel (100) formed from an organic material in terms of blocking foreign substances, but a layer of the display panel (100) formed from an inorganic material can be more easily broken (fragile) than a layer of the display panel (100) formed from an organic material. As a non-limiting example, since the circuit layer (270) of the display panel (100) includes one or more inorganic insulating layers, the circuit layer (270) (or said one or more inorganic insulating layers of the circuit layer (270)) can be broken as a result of bending of a part (290) of the display panel (100), as indicated by an indication (295). For example, the breakage of said one or more inorganic insulating layers of the circuit layer (270) can cause a malfunction of the display panel (100) when light is emitted from each of the light-emitting parts (115). For example, a breakage in one or more inorganic insulating layers of the circuit layer (270) may cause a line defect that renders display impossible through one or more display lines defined within the displayable portion of the display panel (100). For example, a breakage in one or more inorganic insulating layers of the circuit layer (270) may cause a black spot within the displayable portion of the display panel (100).
[0045] Referring to FIG. 3, the display panel (100) may include a displayable portion and a non-displayable portion. The displayable portion of the display panel (100) may be described as a portion of the display panel (100) available for displaying information. The displayable portion of the display panel (100) may be described as an active area. The displayable portion of the display panel (100) may be described as a portion of the display panel (100) configured to emit light under the control of a circuit layer (270) (not shown in FIG. 3). The non-displayable portion of the display panel (100) may be defined at the edge of the display panel (100). The non-displayable portion of the display panel (100) may be placed peripherally to the displayable portion of the display panel (100). The non-displayable portion of the display panel (100) may be described as a portion of the display panel (100) that does not include color filter portions (141), electrodes (134), and light-emitting portions (115) (e.g., light-emitting portions controlled by a circuit layer (270)). The non-displayable portion of the display panel (100) may be described as a portion of the display panel (100) covered by the structure of the electronic device described with reference to FIG. 1 (e.g., the structure of the electronic device associated with the display panel (100)) (e.g., a bezel) (e.g., a front frame portion described with reference to FIG. 7). The non-displayable portion of the display panel (100) may be described as dead space. The non-displayable portion of the display panel (100) may be described as a non-active portion or a non-active area.
[0046] Since the display panel (100) defines the front side of the electronic device, an external impact may be applied to the non-displayable portion of the display panel (100) or to the displayable portion of the display panel (100) adjacent to the non-displayable portion of the display panel (100). For example, the state (391) of the display panel (100) may be described as a state in which an external impact is applied to the non-displayable portion of the display panel (100), as indicated by the indication (393).
[0047] A layer of a display panel (100) formed from an inorganic material is superior to a layer of a display panel (100) formed from an organic material in terms of blocking foreign substances, but a layer of a display panel (100) formed from an inorganic material can be more easily broken (fragile) than a layer of a display panel (100) formed from an organic material. As an example without limitation, the BM portion (142) and layer (150) of a color filter layer (140) are formed from an organic material, but because the BM portion (142) and layer (150) of the color filter layer (140) are adjacent to the location of the display panel (100) where an external impact is directly applied, the BM portion (142) and layer (150) of the color filter layer (140) can be broken by an external impact. As a non-limiting example, since the layers within the touch-sensitive layer (130) (e.g., inorganic flattening layer (131), inorganic insulating layer (132), and inorganic protective layer (133)) are formed from inorganic material, the breakage of the BM portion (142) of the color filter layer (140) and the layer (150) may extend to the touch-sensitive layer (130). As a non-limiting example, since the layers within the touch-sensitive layer (130) (e.g., inorganic flattening layer (131), inorganic insulating layer (132), and inorganic protective layer (133)) are formed from inorganic material, the breakage of the touch-sensitive layer (130) may extend to the encapsulation layer (120). For example, as in state (392), a break (394) of the display panel (100) may occur from the non-displayable portion of the display panel (100) depending on an impact applied to the non-displayable portion of the display panel (100). The break (394) of the display panel (100) may be represented as in image (396).
[0048] For example, foreign substances (e.g., oxygen or moisture) may be inserted into the light-emitting layer (110) through a broken part of the encapsulation layer (120). The foreign substances inserted into the light-emitting layer (110) may oxidize a part (112) of the light-emitting layer (110) (e.g., containing organic material). Oxidation of the part (112) of the light-emitting layer (110) may reduce the light-emitting properties. For example, due to oxidation of the part (112) of the light-emitting layer (110), a black spot may occur within the displayable part (or active part) (or active area) (or display part) of the display panel (100). Such black spots may reduce the quality of the display panel (100).
[0049] The display panel described below (e.g., display panel (400)) may include a structure for reducing breakage of the display panel (100) described with reference to FIG. 1, FIG. 2, and FIG. 3.
[0050] Figure 4 is a simplified block diagram of an electronic device.
[0051] Referring to FIG. 4, the display panel (400) may be included within the display (490) (or display device (490)) (or display assembly (490)) (or display module (490)) of the electronic device (401).
[0052] The electronic device (401) may include at least one processor (480) (e.g., including a processing circuit) and a display (490). The electronic device (401) may include at least a part of the electronic device (901) of FIG. 9 or correspond to at least a part of the electronic device (901) of FIG. 9.
[0053] The form factor of the electronic device (401) may vary. For example, the electronic device (401) may be a bar-type electronic device. For example, the electronic device (401) may be a foldable-type (or single-foldable-type) electronic device. For example, the electronic device (401) may be a multi-foldable-type electronic device. For example, the electronic device (401) may be a rollable-type or sliderable-type electronic device. A display panel (400) within the electronic device (401) may define the front side (or top side) of the electronic device (401).
[0054] At least one processor (480) may generate or acquire an image to be displayed through a display panel (400) and provide the image to a display driving circuit (491) to display the image through the display panel (400). At least one processor (480) may include a central processing unit (e.g., including a processing circuit). At least one processor (480) may include a display processing unit (DPU) (e.g., including a processing circuit). At least one processor (480) may include a graphic processing unit (GPU) (e.g., including a processing circuit) and / or a neural processing unit (NPU) (e.g., including a processing circuit). At least one processor (480) may include at least a part of the processor (920) of FIG. 9 or correspond to at least a part of the processor (920) of FIG. 9.
[0055] The display (490) may include a display driving circuit (491) and a display panel (400). The display (490) may include at least a part of the display module (960) of FIGS. 9 and FIGS. 10 or correspond to at least a part of the display module (960) of FIGS. 9 and FIGS. 10.
[0056] The display driving circuit (491) can control the display panel (400) to display an image obtained from at least one processor (480) through the display panel (400). For example, the display driving circuit (491) can control a gate driver circuit within a circuit layer of the display panel (400). The display driving circuit (491) may include at least a part of the display driver IC (1030) of FIG. 10 or correspond to at least a part of the display driver IC (1030) of FIG. 10.
[0057] The display panel (400) may be used for displaying an image. The display panel (400) may be used to identify inputs received in connection with the display panel (400), such as touch inputs and / or hovering inputs. At least a portion of the display panel (400) may be flexible or deformable. The display panel (400) may include at least a portion of the display (1010) of FIG. 10 or correspond to at least a portion of the display (1010) of FIG. 10.
[0058] The display panel (400) may include a displayable portion (492) and a non-displayable portion (493).
[0059] The displayable portion (492) of the display panel (100) may be described as a portion of the display panel (400) available for displaying information (or an image). The displayable portion (492) of the display panel (400) may be described as an active area. The displayable portion (492) of the display panel (400) may be described as a portion of the display panel (400) configured to emit light under the control of a circuit layer (e.g., circuit layer (570) of FIG. 5) (not shown in FIG. 4). The non-displayable portion (493) of the display panel (100) may be defined at the edge of the display panel (400). The non-displayable portion (493) of the display panel (400) may be placed peripherally to the displayable portion (492) of the display panel (400). The non-displayable portion (493) of the display panel (400) may be described as a portion of the display panel (400) that does not include color filter portions (541) (not shown in FIG. 4), electrodes (534) (not shown in FIG. 4), and light-emitting portions (515) (e.g., light-emitting portions controlled by a circuit layer (570)) (not shown in FIG. 4). The non-displayable portion (493) of the display panel (400) may be described as a portion of the display panel (400) that is covered by a structure of an electronic device (401) (e.g., a structure of the electronic device (401) associated with the display panel (400)) (e.g., a bezel of the electronic device (401)) (e.g., a front frame portion of the electronic device (401) described with reference to FIG. 7). The non-displayable portion (493) of the display panel (400) may be described as dead space. The non-displayable portion (493) of the display panel (400) can be described as a non-active portion or a non-active area.
[0060] The display panel (400) may include a structure for reinforcing the robustness of the display panel (400). For example, the display panel (400) may include a structure for reducing breakage of the display panel (100) described with reference to FIGS. 1, FIGS. 2, and FIGS. 3.
[0061] FIG. 5 illustrates a display panel including a touch-sensitive layer including an organic layer.
[0062] Referring to FIG. 5, the display panel (400) may include a plurality of layers including a substrate layer (560), an organic layer (563), a buffer layer (565), a circuit layer (570), a light-emitting layer (510), an encapsulation layer (520), a touch-sensitive layer (530), a color filter layer (540), and a layer (550).
[0063] A display panel (400) may include a light-emitting layer (510). The light-emitting layer (510) located within a displayable portion (492) of the display panel (400) may include light-emitting portions (515) and an insulating portion (514) that defines the periphery of each of the light-emitting portions (515) of the light-emitting layer (510). The insulating portion (514) may be described as a pixel definition layer (PDL) in that it functions to define a pixel (or subpixel). The insulating portion (514) may be described as an isolation portion (or electrical isolation portion).
[0064] The light-emitting portions (515) may each include light-emitting elements. For example, the light-emitting elements may include light-emitting diodes (LEDs). The LEDs may include organic LEDs (OLEDs). The light-emitting layer (510) may include an anode electrode portion (511) of an LED, a portion (512) containing a light-emitting material (or organic light-emitting material), and a cathode electrode portion (513) of an LED. The light-emitting portions (515) may be defined in a part of the light-emitting layer (510) where the anode electrode portion (511), the portion (512), and the cathode electrode portion (513) overlap each other.
[0065] The display panel (400) may include a sealing layer (520) disposed on (or over) the light-emitting layer (510) to cover the light-emitting layer (510). The sealing layer (520) may be included within the display panel (400) to protect the light-emitting layer (510) from foreign substances (e.g., moisture and / or air) directed toward the light-emitting layer (510). The sealing layer (520) may seal the light-emitting layer (510).
[0066] As a non-limiting example, the encapsulation layer (520) may include a first inorganic layer (521) covering the cathode electrode portion (513) of the light-emitting layer (510). The encapsulation layer (520) may include a second inorganic layer (523) disposed on the first inorganic layer (521) of the encapsulation layer (520). The encapsulation layer (520) may include an organic layer (522) embedded between the first inorganic layer (521) and the second inorganic layer (523). The organic layer (522) may spatially separate the first inorganic layer (521) and the second inorganic layer (523). For example, an organic layer (522) may be embedded between the first inorganic layer (521) and the second inorganic layer (523) to reduce the insertion of foreign matter into the light-emitting layer (510) through pinholes that may occur within the first inorganic layer (521) and / or the second inorganic layer (523).
[0067] The display panel (400) may include a touch-sensitive layer (530) disposed on top of the encapsulation layer (520). The touch-sensitive layer (530) located within the displayable portion (492) of the display panel (400) may include electrodes (534). By example, without limitation, the touch-sensitive layer (530) may be used to identify input received in relation to the display panel (400) based on changes in capacitive coupling between the electrodes (534) and / or changes in capacitive coupling between each of the electrodes (534) and an external object (e.g., a finger or stylus placed on the display panel (100) or over the display panel (400). The touch-sensitive layer (530) may be described as a touch screen panel (TSP).
[0068] The touch-sensitive layer (530) may include an inorganic flattening layer (531). The inorganic flattening layer (531) may be included within the display panel (400) to flatten a portion of the display panel (400) on which the electrodes (534) are to be placed. As an example without limitation, the inorganic flattening layer (531) may be described as a passivation layer.
[0069] First electrodes (534-1), which are a first part of electrodes (534) included within a displayable portion (492) of a display panel (400), may be placed on an inorganic flattening layer (531). The first electrodes (534-1) may extend in a first direction (e.g., the direction of the x-axis or the direction of the y-axis) and be arranged parallel in a second direction (e.g., the direction of the y-axis or the direction of the x-axis) which is (substantially) perpendicular to the first direction.
[0070] The touch-sensitive layer (530) may include an inorganic insulating layer (532). The inorganic insulating layer (532) may be placed on or above the inorganic flattening layer (531) to cover the first electrodes (534-1).
[0071] The second electrodes (534-2), which are a second part of the electrodes (534) included within the displayable portion (492) of the display panel (400), may be disposed on an inorganic insulating layer (532). The second electrodes (534-2) may extend in the second direction and be arranged parallel to the first direction. The inorganic insulating layer (532) may be disposed between the first part and the second part of the electrodes (534). For example, the inorganic insulating layer (532) may be disposed between the first electrodes (534-1) and the second electrodes (534-2) for changes in capacitive coupling between the part of the first electrodes (534-1) and the part of the second electrodes (534-2).
[0072] The touch-sensitive layer (530) may include an inorganic protective layer (533) for protecting the electrodes (534) (or the touch-sensitive layer (530)).
[0073] The touch-sensitive layer (530) may include an organic layer (536) embedded between the inorganic insulating layer (532) and the inorganic protective layer (533) of the touch-sensitive layer (530) to cover at least a portion of the electrodes (534) (e.g., second electrodes (534-2)). The organic layer (536) may be embedded between the inorganic insulating layer (532) and the inorganic protective layer (533) of the touch-sensitive layer (530) described with reference to FIG. 1 or FIG. 3 to reduce the extension (or diffusion) of the inorganic protective layer (533) of the touch-sensitive layer (530) to the encapsulation layer (520). As an example without limitation, the organic layer (536) may be described as a structure for a robust display panel (400).
[0074] As a non-limiting example, the organic layer (536) may be composed of two or more organic layers. For example, the organic layer (536) may include a first organic layer and a second organic layer disposed on the first organic layer. As a non-limiting example, the organic layer (536) may include an inorganic layer embedded between the first organic layer and the second organic layer of the organic layer (536). The inorganic layer may be covered by the first organic layer and the second organic layer of the organic layer (536).
[0075] A display panel (400) may include a color filter layer (540) placed on or above a touch-sensitive layer (530). The color filter layer (540) may be included within the display panel (400) for visual quality (e.g., visual quality of information displayed through the display panel (400)) that is not reduced or is relatively less reduced depending on external light (e.g., sunlight) reaching the display panel (400). A color filter layer (540) located within a displayable portion (492) of the display panel (400) may include color filter portions (541) each aligned with the light-emitting portions (515) of the light-emitting layer (510), and a black matrix (BM) portion (542) defining the edges of each of the color filter portions (541) of the color filter layer (540). The BM portion (542) may be described as an opaque portion. The BM portion (542) may be described as a light-blocking portion. The color filter portions (541) of the color filter layer (540) may each overlap with the light-emitting portions (515) of the light-emitting layer (510). Each of the color filter portions (541) of the color filter layer (540) may be configured to allow light of a color corresponding to the color of light emitted from the light-emitting portions (515) of the light-emitting layer (510) (e.g., red, blue, or green) to pass through, and to disallow light of a color that does not correspond to (or is different from) the color of light emitted from the light-emitting portions (515) of the light-emitting layer (510).
[0076] The display panel (400) may include a layer (550) placed on top of a color filter layer (540). The layer (550) may be placed on top of the color filter layer (540) to flatten the display panel (400). The layer (550) may be described as an overcoating layer.
[0077] The display panel (400) may include a substrate layer (560). The substrate layer (560) may be formed from polyimide. The substrate layer (560) may be flexible or deformable.
[0078] The display panel (400) may include an organic layer (563) disposed on or above a substrate layer (560). The organic layer (563) may be included within the display panel (400) to reduce the occurrence, diffusion, or extension of cracks in the display panel (400) to the circuit layer (570) as described with reference to FIG. 2. The organic layer (563) may be contained between the substrate layer (560) and the circuit layer (570).
[0079] The display panel (400) may include a buffer layer (565) formed on an organic layer (563). The buffer layer (565) may be placed on or above the organic layer (563). The buffer layer (565) may be included in the display panel (400) to reduce the movement of material (or foreign material) that may occur when forming a circuit layer (570) (e.g., an active layer (not shown in FIG. 5) within the circuit layer (570) (e.g., formed from LTPS (low-temperature polycrystalline silicon) or LTPO (low-temperature polycrystalline oxide)). The buffer layer (565) may be described as being included within the circuit layer (570).
[0080] The display panel (400) may include a circuit layer (570). The circuit layer (570) may be formed on a buffer layer (565). The circuit layer (570) may be placed on top of the buffer layer (565). The circuit layer (570) may be placed below a light-emitting layer (510). The circuit layer (570) may include transistors configured to control light emission from each of the light-emitting portions (515). The transistors may be described as light-emitting driving circuitry or light-emitting driving circuits. The circuit layer (570) may include a gate driver circuit.
[0081] The circuit layer (570) may include the active layer. The circuit layer (570) may include one or more inorganic insulating layers and / or one or more organic insulating layers.
[0082] The position of the organic layer (563) may be changed according to the embodiment. For example, as in the example configuration (591), the organic layer (563) may not be located between the substrate layer (560) and the buffer layer (565), but may be located between the buffer layer (565) and the circuit layer (570). Although not shown in FIG. 5, the organic layer (563) may be located between the substrate layer (560) and the buffer layer (565), and between the buffer layer (565) and the circuit layer (570). For example, the organic layer (563) may be composed of two or more layers. As a non-limiting example, the organic layer (563) may include a first organic layer and a second organic layer disposed on the first organic layer. As a non-limiting example, the organic layer (563) may include an inorganic layer embedded between the first organic layer and the second organic layer of the organic layer (563). The inorganic layer may be covered by the first organic layer and the second organic layer of the organic layer (563).
[0083] As described above, the display panel (400) can be more robust by including an organic layer (536) and / or an organic layer (563) of the touch-sensitive layer (530).
[0084] FIG. 6 illustrates a display panel comprising a touch-sensitive layer including one or more discontinuous inorganic layers.
[0085] Referring to FIG. 6, the display panel (400) may include a plurality of layers including a substrate layer (560), an organic layer (563), a buffer layer (565), a circuit layer (570), a light-emitting layer (510), an encapsulation layer (520), a touch-sensitive layer (530), a color filter layer (540), and a layer (550).
[0086] A display panel (400) may include a light-emitting layer (510). A light-emitting layer (510) located within a non-displayable portion (493) of the display panel (400) may include an insulating portion (514). As a non-limiting example, a light-emitting layer (510) located within a non-displayable portion (493) of the display panel (400) may include a cathode electrode portion (513). As a non-limiting example, a light-emitting layer (510) located within a non-displayable portion (493) of the display panel (400) may not include light-emitting portions (515). As a non-limiting example, a light-emitting layer (510) located within a non-displayable portion (493) of the display panel (400) may not include an anode electrode portion (511) and a portion (512).
[0087] The display panel (400) may include a sealing layer (520) disposed on (or over) the light-emitting layer (510) to cover the light-emitting layer (510). The sealing layer (520) may be included within the display panel (400) to protect the light-emitting layer (510) from foreign substances (e.g., moisture and / or air) directed toward the light-emitting layer (510). The sealing layer (520) may seal the light-emitting layer (510).
[0088] As a non-limiting example, the encapsulation layer (520) may include a first inorganic layer (521) covering the cathode electrode portion (513) of the light-emitting layer (510). The encapsulation layer (520) may include a second inorganic layer (523) disposed on the first inorganic layer (521) of the encapsulation layer (520). The encapsulation layer (520) may include an organic layer (522) embedded between the first inorganic layer (521) and the second inorganic layer (523). The organic layer (522) may spatially separate the first inorganic layer (521) and the second inorganic layer (523). For example, an organic layer (522) may be embedded between the first inorganic layer (521) and the second inorganic layer (523) to reduce the insertion of foreign matter into the light-emitting layer (510) through pinholes that may occur within the first inorganic layer (521) and / or the second inorganic layer (523).
[0089] The display panel (400) may include a touch-sensitive layer (530) disposed on top of an encapsulation layer (520). The touch-sensitive layer (530) located within a non-displayable portion (493) of the display panel (400) may not include electrodes (534).
[0090] The touch-sensitive layer (530) may include an inorganic flattening layer (531). The inorganic flattening layer (531) may be included within the display panel (400) to flatten a portion of the display panel (400). As an example without limitation, the inorganic flattening layer (531) may be described as a passivation layer.
[0091] The touch-sensitive layer (530) may include an inorganic insulating layer (532). The inorganic insulating layer (532) may be placed on or above the inorganic flattening layer (531) within the non-displayable portion (493) of the display panel (400).
[0092] The inorganic flattening layer (531) and the inorganic insulating layer (532) of the touch-sensitive layer (530) may be discontinuous. For example, the inorganic flattening layer (531) and the inorganic insulating layer (532) of the touch-sensitive layer (530) may be discontinuous within the non-displayable portion (493) of the display panel (400), as indicated by the indication (600). The inorganic flattening layer (531) and the inorganic insulating layer (532) of the touch-sensitive layer (530) may be continuous within the displayable portion (492) of the display panel (400). However, they are not limited thereto. For example, the inorganic flattening layer (531) and the inorganic insulating layer (532) of the touch-sensitive layer (530) may be discontinuous within the displayable portion (492) of the display panel (400).
[0093] For example, as indicated by the indication (600), the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) within the non-displayable portion (493) of the display panel (400) can at least partially cover the inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) within the non-displayable portion (493) of the display panel (400).
[0094] The touch-sensitive layer (530) may include an organic layer (536). The organic layer (536) may cover the inorganic flattening layer (531) and the inorganic insulating layer (532) of the touch-sensitive layer (530) that are discontinuous within the non-displayable portion (493) of the display panel (400), as indicated by the indication (600).
[0095] As a non-limiting example, the organic layer (536) located within the non-displayable portion (493) may be composed of two or more organic layers. For example, the organic layer (536) located within the non-displayable portion (493) may include a first organic layer and a second organic layer disposed on the first organic layer. As a non-limiting example, the organic layer (536) located within the non-displayable portion (493) may include an inorganic layer embedded between the first organic layer and the second organic layer of the organic layer (536). The inorganic layer may be covered by the first organic layer and the second organic layer of the organic layer (536).
[0096] The inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) and the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) can be described as an island structure included within the touch-sensitive layer (530). Since the inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) and the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) reduce the portion of the touch-sensitive layer (530) formed from an inorganic material, the inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) and the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) can reduce the probability that a breakage (394) of the display panel (100) described with reference to FIG. 3 will occur within the display panel (400). The inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) and the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) can be described as a structure for a robust display panel (400).
[0097] The touch-sensitive layer (530) may include an inorganic protective layer (533) placed on or above the organic layer (536).
[0098] The inorganic protection layer (533) of the touch-sensitive layer (530) may be discontinuous. For example, the inorganic protection layer (533) of the touch-sensitive layer (530) may be discontinuous within the non-displayable portion (493) of the display panel (400), as indicated by the indication (601). The inorganic protection layer (533) of the touch-sensitive layer (530) may be continuous within the displayable portion (492) of the display panel (400). However, it is not limited thereto. For example, the inorganic protection layer (533) of the touch-sensitive layer (530) may be discontinuous within the displayable portion (492) of the display panel (400).
[0099] The inorganic protective layer (533) of the discontinuous touch-sensitive layer (530) can be described as an island structure included within the touch-sensitive layer (530). Since the inorganic protective layer (533) of the discontinuous touch-sensitive layer (530) reduces the portion of the touch-sensitive layer (530) formed from an inorganic material, the inorganic protective layer (533) of the discontinuous touch-sensitive layer (530) can reduce the probability that a breakage (394) of the display panel (100) described with reference to FIG. 3 will occur within the display panel (400). The inorganic protective layer (533) of the discontinuous touch-sensitive layer (530) can be described as a structure for a robust display panel (400).
[0100] As a non-limiting example, the display panel (400) may include an inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530), an inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530), and an inorganic protective layer (533) of the discontinuous touch-sensitive layer (530). As a non-limiting example, the first island structure defined by the inorganic flattening layer (531) of the discontinuous touch-sensitive layer (530) and the inorganic insulating layer (532) of the discontinuous touch-sensitive layer (530) and the second island structure defined by the inorganic protective layer (533) of the discontinuous touch-sensitive layer (530) may alternate with each other (when viewed from above), as illustrated in FIG. 6. For example, the first island structure and the second island structure that alternate with each other can further reduce the probability that a breakage (394) of the display panel (100) described with reference to FIG. 3 will occur within the display panel (400).
[0101] As a non-limiting example, the size of the first island structure may differ from the size of the second island structure. As a non-limiting example, the size of the first island structure included within the touch-sensitive layer (530) located within the displayable portion (492) of the display panel (400) may differ from the size of the first island structure included within the touch-sensitive layer (530) located within the non-displayable portion (493) of the display panel (400). As a non-limiting example, the size of the second island structure included within the touch-sensitive layer (530) located within the displayable portion (492) of the display panel (400) may differ from the size of the second island structure included within the touch-sensitive layer (530) located within the non-displayable portion (493) of the display panel (400). As a non-limiting example, the difference between the size of the first island structure included in the touch-sensitive layer (530) located within the displayable portion (492) of the display panel (400) and the size of the first island structure included in the touch-sensitive layer (530) located within the non-displayable portion (493) of the display panel (400) may differ from the difference between the size of the second island structure included in the touch-sensitive layer (530) located within the displayable portion (492) of the display panel (400) and the size of the second island structure included in the touch-sensitive layer (530) located within the non-displayable portion (493) of the display panel (400).
[0102] As a non-limiting example, the shape of the first island structure included within the touch-sensitive layer (530) may be a rectangle (or rounded rectangle), a trapezoid (or rounded trapezoid), or an inverted trapezoid (or rounded inverted trapezoid) when viewed from the lateral side (e.g., left side, right side, top side, or bottom side) of the display panel (400). As a non-limiting example, the size of the first island structure (e.g., the width of the first island structure) may be larger as it gets closer to the periphery of the display panel (400). As a non-limiting example, the size of the first island structure may be smaller as it gets closer to the periphery of the display panel (400). As a non-limiting example, the size of the first island structure may be the same regardless of its position on the display panel (400).
[0103] As a non-limiting example, the shape of the second island structure included within the touch-sensitive layer (530) may be a rectangle (or rounded rectangle), a trapezoid (or rounded trapezoid), or an inverted trapezoid (or rounded inverted trapezoid) when viewed from the lateral side (e.g., left side, right side, top side, or bottom side) of the display panel (400). As a non-limiting example, the size of the second island structure (e.g., the width of the second island structure) may be larger as it is closer to the periphery of the display panel (400). As a non-limiting example, the size of the second island structure may be smaller as it is closer to the periphery of the display panel (400). As a non-limiting example, the size of the second island structure may be the same regardless of its position on the display panel (400).
[0104] The display panel (400) may include a color filter layer (540) placed on or above a touch-sensitive layer (530). The color filter layer (540) located within the non-displayable portion (493) of the display panel (400) may include a BM portion (542). The color filter layer (540) located within the non-displayable portion (493) of the display panel (400) may not include color filter portions (541). The BM portion (542) of the color filter layer (540) located within the non-displayable portion (493) of the display panel (400) may cover the inorganic protection layer (533) of the discontinuous touch-sensitive layer (530) within the non-displayable portion (493) of the display panel (400), as indicated by the indication (601).
[0105] The display panel (400) may include a layer (550) placed on top of a color filter layer (540). The layer (550) may be placed on top of the color filter layer (540) to flatten the display panel (400).
[0106] The display panel (400) may include a substrate layer (560). The substrate layer (560) may be formed from polyimide. The substrate layer (560) may be flexible or deformable.
[0107] The display panel (400) may include an organic layer (563) disposed on or above a substrate layer (560). The organic layer (563) may be embedded between the substrate layer (560) and the circuit layer (570).
[0108] The display panel (400) may include a buffer layer (565) formed on an organic layer (563). The buffer layer (565) may be placed on or above the organic layer (563). The buffer layer (565) may be described as being included within a circuit layer (570).
[0109] The display panel (400) may include a circuit layer (570). The circuit layer (570) may be formed on a buffer layer (565). The circuit layer (570) may be placed on top of the buffer layer (565). The circuit layer (570) may be placed below a light-emitting layer (510). The circuit layer (570) may include a gate driver circuit within a non-displayable portion (493) of the display panel (400).
[0110] The position of the organic layer (563) may be changed according to the embodiment. For example, as in the example configuration (591) of FIG. 5, the organic layer (563) may not be located between the substrate layer (560) and the buffer layer (565), but may be located between the buffer layer (565) and the circuit layer (570). Although not shown in FIG. 6, the organic layer (563) may be located between the substrate layer (560) and the buffer layer (565), and between the buffer layer (565) and the circuit layer (570).
