[0047] The display area DA may mean an area in which pixels PXL are arranged. The non-display area NDA may mean an area in which pixels PXL are not arranged. Lines and pads connected to the pixels PXL of the display area DA may be arranged in the non-display area NDA.
[0048] According to the embodiment, the structure, PENTILE TM The pixel PXL (or sub-pixel SPX) is provided with a configuration structure, etc. However, the present disclosure is not limited thereto, and various embodiments may be applied to the present disclosure.
[0049] According to an embodiment, a pixel PXL (or subpixel SPX) may include a first subpixel SPXL1, a second subpixel SPXL2, and a third subpixel SPXL3.

However, the colors, types, and / or numbers of the first sub-pixels SPXL1, the second sub-pixels SPXL2, and the third sub-pixels SPXL3 that constitute each pixel unit are not limited to specific examples.
[0051] Figure 2 is a schematic cross-sectional view illustrating a display device according to an embodiment of the present disclosure.
[0052] refer to Figure 2 , the display device DD may include a display panel DP, a cover layer CG and a lower layer HGL.
[0053] The display panel DP may include a pixel circuit layer PCL (eg, a backplane layer) including a base layer BSL and a display layer DL disposed on the pixel circuit layer PLC.
[0054] The display panel DP may include a first surface SF1 and a second surface SF2. The first surface SF1 may be a front surface, and the second surface SF2 may be a rear surface. The first surface SF1 may be adjacent to the display layer DL. The second surface SF2 may be adjacent to the pixel circuit layer PCL.
[0055] The pixel circuit layer PCL may be a layer including a pixel circuit for driving the pixel PXL formed by the display layer DL (or a light emitting element included in the display layer DL).

[0056] The display layer DL may be arranged on the pixel circuit layer PCL. In some embodiments, the display layer DL may include a light-emitting element. In some embodiments, the light-emitting element may include an organic light-emitting diode (OLED). In other embodiments, the light-emitting element may include an inorganic light-emitting element including an inorganic material. In other embodiments, the display layer DL may include a liquid crystal display (LCD). However, the present disclosure is not limited thereto.
[0057] In some embodiments, the display layer DL may further include a polarization layer POL disposed adjacent to the cover layer CG (see FIG. Figure 9). The polarization layer POL may allow light provided from the display layer DL to be transmitted therethrough and reflect light introduced from the outside. In some embodiments, the polarization layer POL may include a polarizer that polarizes light applied along a polarization axis.
[0058] The cover layer CG may be disposed on the first surface SF1 of the display panel DP. The cover layer CG may be disposed substantially at the outside with respect to the display direction (eg, the third direction DR3). In some embodiments, the cover layer CG may include a cover glass.
[0059] In some embodiments, the cover layer CG may cover the front surface of the display panel DP. In some embodiments, the cover layer CG may protect the display panel DP and include a glass material (eg, ultra-thin glass). However, the present disclosure is not limited thereto.
[0060] The lower layer HGL may be disposed on the second surface SF2 of the display panel DP. The lower layer HGL may cover the rear surface of the display panel DP.
[0061] In some embodiments, the lower HGL layer may include a heat dissipation layer and form a heat dissipation structure. For example, the lower HGL layer may include a material with relatively high thermal conductivity. In some embodiments, the lower HGL layer may form part of a ground path. For example, the lower HGL layer may include a material with electrical conductivity. In some embodiments, the lower HGL layer may include copper (Cu). However, the present disclosure is not limited thereto.
[0062] The structure of the display device DD including the conductive resin member CRS is described as a structure in which a ground path for reducing electrostatic discharge (ESD) risk is formed. For convenience of description, descriptions of portions overlapping with those described above will be simplified or will not be repeated.
[0063] Figure 3 is a schematic plan view illustrating a display device according to an embodiment of the present disclosure. Figure 3 Schematically illustrates a planar structure in which the display device DD is viewed from the bottom. For example, Figure 3 Components disposed under the display panel DP (eg, the base layer BSL) may be schematically illustrated.
[0064] Figure 4 is a schematic block diagram illustrating a ground path according to an embodiment of the present disclosure. For example, Figure 4 The figure schematically illustrates the connection relationship between conductive components forming a ground path according to an embodiment of the present disclosure.
[0065] Figure 5 is a schematic diagram illustrating a conductive resin member according to an embodiment of the present disclosure. Figure 5Materials forming the conductive resin member CRS according to an embodiment of the present disclosure are schematically illustrated.
[0066] refer to Figures 3 to 5 , the display device DD may further include a driving circuit part PCB, a battery part BAT, and a conductive resin part CRS arranged on the rear surface of the base layer BSL (eg, the second surface SF2 of the display panel DP).
[0067] In some embodiments, the lower HGL may be completely disposed on the rear surface of the base layer BSL. For example, the lower HGL may extend onto a plane defined by the first direction DR1 and the second direction DR2. In some embodiments, the lower HGL may overlap the drive circuit component PCB, the battery component BAT, and the conductive resin component CRS in a plan view. In some embodiments, the lower HGL may cover a wider area of the display panel DP in a plan view than the drive circuit component PCB.
[0068] In some embodiments, the driving circuit part PCB may be arranged to overlap the conductive resin part CRS and the lower layer HGL on the rear surface of the base layer BSL. In some embodiments, the driving circuit part PCB may not overlap the battery part BAT in a plan view.
[0069] In some embodiments, the driving circuit component PCB may include a circuit board and a driver chip. The circuit board and the driver chip may be electrically connected to each other. The circuit board may include a driving circuit. The driver chip may include a scan driver capable of supplying scan signals for driving the pixels PXL and a data driver capable of supplying data signals for driving the pixels PXL. In some embodiments, the circuit board may be a flexible circuit board. In some embodiments, the driving circuit component PCB may be electrically connected to the pixel circuit.
[0070] In some embodiments, the driving circuit component PCB may include a cover component C-IC. The cover component C-IC may be arranged adjacent to one side of the display panel DP. For example, the cover component C-IC may be part of the driving circuit component PCB and may be arranged on a side adjacent to the folding area FA of the display panel DP. The folding area FA may refer to an area in which a portion of the display panel DP is bent. The folding area FA may be adjacent to one side of a non-folding area NFA, which is an area in which the display panel DP is not bent. In some embodiments, the cover component C-IC may include a structure in which a conductive structure is patterned on a film.
[0071] In some embodiments, the driving circuit component PCB (eg, the cover component C-IC) may include a ground line GL. For example, the ground line GL may form a ground source as at least a portion of a conductive structure formed in the cover component C-IC.
[0072] The battery component BAT may be disposed on the rear surface of the base layer BSL. In some embodiments, the battery component BAT may be disposed so as not to overlap with the drive circuit component PCB in a plan view. In some embodiments, the battery component BAT may store and supply power required for the operation of the display device DD.
[0073] In some embodiments, the battery component BAT may not overlap with the conductive resin component CRS in plan view. For example, the conductive resin component CRS may be selectively arranged in a portion of the rear surface of the base layer BSL that is not directly adjacent to the battery component BAT. This facilitates replacement and repair of the battery component BAT.
[0074] The conductive resin component CRS may be completely arranged on the rear surface of the base layer BSL. For example, the conductive resin component CRS may extend onto a plane defined by the first direction DR1 and the second direction DR2. The conductive resin component CRS may overlap with the drive circuit component PCB (e.g., the cover component C-IC) and the lower layer HGL in a plan view.
[0075] refer to Figure 4 , the conductive resin member CRS may form a portion of a ground path for eliminating at least a portion of ESD. The display device DD according to an embodiment of the present disclosure may include a ground path capable of eliminating at least a portion of ESD.
[0076] ESD formed at the inside or outside of the display device DD may be discharged to the outside along a ground path of the display device DD, and thus, risks due to ESD in the display device DD can be reduced.
[0077] The ground path may include a ground line GL, a conductive resin member CRS, and a set standoff SET.
[0078] In some embodiments, the conductive resin component CRS may have conductive properties. Figure 5 , the conductive resin member CRS may include conductive particles MT and resin MO.
[0079] The conductive particles MT may be made of a conductive material. For example, the conductive particles MT may be made of a metal. The conductive particles MT may include one or more metal materials having low resistance. For example, the conductive particles MT may include at least one selected from the group consisting of aluminum (Al), gold (Au), copper (Cu), graphene, and zinc (Zn). However, the present disclosure is not limited thereto.
[0080] The resin MO may include various materials. For example, the resin MO may include an acrylic material. However, the present disclosure is not limited thereto.
[0081] In some embodiments, the conductive resin component CRS may be a member of a base resin cured to include conductive particles MT that is thermally cured or photocured (e.g., ultraviolet (UV) cured). For example, the base resin may include a material for forming the resin MO (e.g., an acrylic monomer). The base resin may also include a photoinitiator or a thermal initiator. Thus, the resin MO provided by curing may also include a photoinitiator or a thermal initiator. However, the present disclosure is not limited thereto.
[0082] In some embodiments, the conductive resin member CRS may be electrically connected to the ground line GL. For example, the conductive resin member CRS may form an electrical contact surface with the ground line GL. In some embodiments, at least a portion of the ground line GL and the conductive resin member CRS may be in contact with each other.
[0083] In some embodiments, the conductive resin member CRS may be electrically connected to the setting support SET. For example, the conductive resin member CRS may form an electrical contact surface with the setting support SET. In some embodiments, at least a portion of the setting support SET and the conductive resin member CRS may be in contact with each other.
[0084] Therefore, ESD can be discharged to the outside through the ground path.
[0085] According to an embodiment, the conductive resin member CRS distributed in a relatively wide area under the display panel DP may form a ground path. The conductive resin member CRS may relatively widely define a contact surface with other components.
[0086] Experimentally, it can be difficult to ensure reliable grounding performance when the component forming the ground path covers a narrow area. For example, when a conductive pin or the like is used to form the ground path, an oxide layer may form in the area between the conductive pin and another component electrically contacting the conductive pin, making it difficult to properly define the ground path.
[0087] However, according to the embodiment of the present disclosure, the conductive resin member CRS covering a relatively wide area, rather than the conductive pin defined in a narrow area, can form a ground path, and therefore, a ground path with high reliability can be formed.
[0088] Will combine Figures 6 to 10 A cross-sectional structure of a display device DD including the conductive resin member CRS is described.
[0089] Figures 6 to 9 is a schematic cross-sectional view illustrating a display device according to an embodiment of the present disclosure. For example, Figure 6 It is along Figure 3 Schematic cut-away cross-sectional view taken along line AA′ shown in FIG. Figure 7 It is along Figure 3 Schematic cut-sectional view taken along line BB' shown in FIG. Figure 8 It is along Figure 3 Schematic cut-sectional view taken along line CC' shown in FIG. Figure 9 It is along Figure 3 Schematic cut-sectional view taken along line DD' shown in FIG.
[0090] Figure 10 : is a view schematically illustrating a positional relationship of a conductive resin member in a region adjacent to a folding region according to an embodiment of the present disclosure. Figure 10 The structure in which the conductive resin member CRS is arranged in the space defined by the folded display panel DP can be schematically illustrated.
[0091] The display device DD according to an embodiment of the present disclosure may further include a shield can SCA, a gasket GAS, a middle frame MFR, and an adhesive part GLU.
[0092] refer to Figures 6 to 10 , the shield can SCA, the gasket GAS, and the middle frame MFR may be disposed under the display panel DP (eg, the base layer BSL) and between the lower layer HGL and the set support SET.
[0093] The shielding can SCA may be disposed on the drive circuit component PCB. The shielding can SCA may be disposed below the display panel DP (e.g., the base layer BSL) and between the gasket GAS and the drive circuit component PCB. The shielding can SCA may protect other components from electromagnetic interference. The shielding can SCA may include a metal material. However, the present disclosure is not limited thereto.
[0094] The gasket GAS may be disposed on the driving circuit component PCB. The gasket GAS may be disposed between the lower layer HGL and the shielding can SCA. The gasket GAS may protect components of the display device DD from external influences (dust, electromagnetic waves, etc.).
[0095] The middle frame MFR may be disposed below the lower layer HGL (e.g., the base layer BSL) and between the setting bracket SET and the display panel DP. The middle frame MFR may include a material having relatively high rigidity. In some embodiments, at least a portion of the middle frame MFR may be covered with a conductive resin member CRS and coupled to the setting bracket SET via an adhesive member GLU including various adhesive materials.
[0096] The positioning bracket SET may form a lower member of the display device DD. The positioning bracket SET may form a housing of the display device DD. The positioning bracket SET may be disposed under the display panel DP.
[0097] The positioning bracket SET may cover the conductive resin member CRS. For example, the positioning bracket SET may form a contact surface with the conductive resin member CRS and be electrically connected to the conductive resin member CRS. The positioning bracket SET may be coupled to the cover layer CG. The positioning bracket SET may be connected to the intermediate frame MFR via an adhesive member GLU.
[0098] As described above, the setting bracket SET can form a ground path.
[0099] The positioning bracket SET may include a rigid material and be conductive. The conductive material included in the positioning bracket SET is not particularly limited. The positioning bracket SET may fix the display panel DP. The positioning bracket SET may stably hold the components of the display device DD.
[0100] In some embodiments, the display device DD may include a folding area FA in which a portion of the display panel DP is bent and a non-folding area NFA in which the display panel DP is not bent.
[0101] In some embodiments, the polarization layer POL may be disposed in the non-folding area NFA and may not be disposed in the folding area FA. The lower layer HGL may be disposed in the non-folding area NFA and may not be disposed in the folding area FA.
[0102] In some embodiments, the cover layer CG may be disposed in the entire non-folding area NFA from the folding area FA. In some embodiments, the conductive resin member CRS may be disposed in the entire non-folding area NFA from the folding area FA.
[0103] In some embodiments, the conductive resin member CRS can fill at least a portion of the space within the folding area FA. For example, the conductive resin member CRS can be arranged in the inner region formed when the display panel DP is bent, and can be arranged in the outer region formed when the display panel DP is bent. Therefore, the conductive resin member CRS in the folding area FA can couple the display panel DP, the cover layer CG, and the set support SET to each other. Therefore, the conductive resin member CRS can protect the components in the folding area FA and ensure the stability of the entire display device DD.
[0104] According to the embodiment ( Figure 10 ), the lower layer HGL may include a first lower layer HGL1 and a second lower layer HGL2, and the display device DD may further include a filling layer FIL disposed between the first lower layer HGL1 and the second lower layer HGL2. In some embodiments, the first lower layer HGL1 may be adjacent to a portion of the display panel DP formed at the front surface, and the second lower layer HGL2 may be adjacent to a portion of the display panel DP formed at the rear surface. Depending on the embodiment, the conductive resin member CRS may be directly adjacent to the filling layer FIL, the first lower layer HGL1, and the second lower layer HGL2 in the folding area FA.
[0105] In some embodiments, the display device DD may further include a protective layer BPL for protecting the display panel DP in the folding area FA. The protective layer BPL may be arranged from the folding area FA throughout the non-folding area NFA. The protective layer BPL may be formed using the same process as at least one of the multiple insulating layers used to form the display panel DP. In some embodiments, the protective layer BPL may be arranged on another portion of the display panel DP, which is arranged below the display panel DP that forms the front surface when at least a portion of the protective layer BPL is bent. The protective layer BPL may include an inorganic material. However, the present disclosure is not limited to specific examples.
[0106] The battery component BAT may be disposed on the setting support SET. The battery component BAT may be disposed between the lower layer HGL and the setting support SET.
[0107] In some embodiments, the display device DD may include a partition wall PAR. The partition wall PAR may be adjacent to the battery assembly BAT. In some embodiments, the battery assembly BAT and the conductive resin assembly CRS may be separated from each other. In some embodiments, the partition wall PAR may include a rigid material. In some embodiments, the partition wall PAR may be integrally formed with the setting support SET.
[0108] In some embodiments, the partition wall PAR may be adjacent to the battery component BAT. In the case where a base resin is supplied downward from the display panel DP to form the conductive resin component CRS, the risk of the base resin being directly adjacent to the battery component BAT can be prevented. The base resin can be provided as a cured conductive resin component CRS when the curing process is performed. In the case where the cured conductive resin component CRS is directly adjacent to the battery component BAT, the battery component BAT may be coupled to the conductive resin component CRS arranged in the upper half below the display panel DP. This may be disadvantageous in terms of repair, replacement, etc. of the battery component BAT. However, the partition wall PAR is formed so that the above-mentioned risk can be prevented.
[0109] The conductive resin member CRS may be disposed under the display panel DP to be adjacent to one or more components.
[0110] The conductive resin member CRS may be disposed between the driving circuit member PCB and the setting bracket SET. The conductive resin member CRS may be disposed between the middle frame MFR and the lower layer HGL. The conductive resin member CRS may be directly adjacent to the middle frame MFR.
[0111] Therefore, the conductive resin member CRS may fill the area under the display panel DP. The conductive resin member CRS may support components of the display device DD while serving as a ground path for eliminating ESD.
[0112] For example, the conductive resin member CRS may be prepared by injecting a base resin including the resin MO and the conductive particles MT into a portion under the display panel DP during a manufacturing process of the display device DD and curing the base resin.
[0113] When the base resin is supplied to the portion below the display panel DP, the base resin can fill the area below the display panel DP due to its relatively flexible nature. Thereafter, the base resin can be thermally cured or photocured (eg, ultraviolet (UV) cured).
[0114] When the manufacturing process of the display device DD is performed, the process of supplying the base resin to the portion under the display panel DP and the curing process can be performed without adding additional process facilities or excessive changes in the process procedure.
[0115] The conductive resin member CRS can be formed using a base resin that does not have excessive rigidity, and thus damage to the display panel DP and components thereunder can be prevented.
[0116] As described above, the conductive resin member CRS can be electrically connected to the setting support SET over a wide area, and can also be electrically connected to the underlying HGL over a wide area. For example, compared to relatively sharp electrical connection members (e.g., conductive pins), the conductive resin member CRS can be electrically connected to another component over a wide area (e.g., an area extending on a plane).
[0117] For example, in an edge region of the display panel DP corresponding to a side at which the cover part C-IC is not arranged (see Figures 6 to 8 ), the conductive resin part CRS may be electrically connected to a ground line GL included in the driving circuit part PCB and contact the setting support SET.
[0118] For example, in an edge region of the display panel DP corresponding to a side at which the cover part C-IC is arranged (see Figure 9 ), the conductive resin part CRS may be electrically connected to a ground line GL included in the driving circuit part PCB and contact the setting support SET.
[0119] Therefore, according to the embodiment of the present disclosure, the process is optimized and the grounding performance is enhanced. Therefore, the reliability of the electrical characteristics applied to the entire display device DD can be improved, and the stability of the display device DD can be ensured.
[0120] According to the present disclosure, it is possible to provide a display device in which a ground path having improved grounding performance is defined, so that risks due to ESD can be reduced.
[0121] According to the present disclosure, it is possible to provide a display device in which structural stability can be ensured.
[0122] Example embodiments have been disclosed herein, and although specific terms are employed, they are used and to be interpreted in a generic and descriptive sense only and not for purposes of limitation.
