[0059] The mobile unit TRU in the display device manufacturing apparatus 10 of the embodiment may be a unit for moving the display module ion-treated in the ion treatment unit ITU. The ion-treated display module is moved to other facilities of the display device manufacturing apparatus 10 using the mobile unit TRU and then manufactured into a display device through a continuous process.
[0060] The inspection unit (ISU) in the display device manufacturing apparatus 10 of the embodiment can be used to inspect the quality of the display module.

The display module DM can provide an image to the user through the display surface. In this specification, the front surface (or top surface) and the rear surface (or bottom surface) of each component are defined based on the direction in which the image is displayed.

[0077] The input sensor ISP may be provided on the display panel DP. The input sensor ISP may sense external input applied from the outside. The external input may include various types of external inputs, including a part of the user's body, light, heat, a pen, pressure, and the like. The input sensor ISP may provide an input signal including information about the external input, so that the display panel DP may sense the external input and generate an image corresponding to the external input. The input sensor ISP may be driven in various ways using static capacitance, a resistive film, infrared rays, sound waves, or pressure, and the driving method is not limited to a specific method. In an embodiment, the input sensor ISP will be described as being driven in a static capacitance manner.
[0078] The input sensor ISP may be disposed on the display panel DP through a continuous process. In this case, the input sensor ISP may be directly disposed on the display panel DP. Directly disposed may mean that no third element is disposed between the input sensor ISP and the display panel DP. In other words, a separate adhesive member may not be disposed between the input sensor ISP and the display panel DP.
[0079] refer to Figure 3BThe input sensor ISP may include a sensor base layer ISL-B, sensor conductive layers MTL1 and MTL2, and sensor insulating layers ISL-C and ISL-T. The sensor base layer ISL-B may be directly disposed on the display panel DP.
[0080] The input sensor ISP may include a sensor base layer ISL-B, sensor conductive layers MTL1 and MTL2 disposed on the sensor base layer ISL-B, and sensor insulating layers ISL-C and ISL-T disposed on the sensor base layer ISL-B. For example, the input sensor ISP in an embodiment may include a sensor base layer ISL-B, a first sensor conductive layer MTL1, a first sensor insulating layer ISL-C, a second sensor conductive layer MTL2, and a second sensor insulating layer ISL-T sequentially stacked on the display panel DP in the third direction DR3.
[0081] The sensor base layer ISL-B may be an inorganic layer including at least one of silicon nitride, silicon oxynitride, and silicon oxide. Alternatively, the sensor base layer ISL-B may be an organic layer including epoxy resin, acrylic resin, or imide resin. The sensor base layer ISL-B may have a single-layer structure or a multi-layer structure having layers stacked in the third direction DR3.
[0082] Each of the first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T may include silicon nitride (SiN X ) and silicon oxynitride (SiO X N Y ) In addition, each of the first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T may include silicon oxide (SiO X ).

X ), silicon oxynitride (SiO X N Y ) and silicon oxide (SiO X ), X and Y are each greater than 0.
[0083] The first sensor insulating layer ISL-C may be disposed on the first sensor conductive layer MTL1. The second sensor insulating layer ISL-T may be disposed on the second sensor conductive layer MTL2. The first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T may each include an inorganic film. Alternatively, the first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T may each include an organic film.
[0084] When the first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T each include an organic film, the organic film may include at least one of an acrylic-based resin, a methacrylic-based resin, a polyisoprene-based resin, a vinyl-based resin, an epoxy-based resin, a urethane-based resin, a cellulose-based resin, a siloxane-based resin, a polyimide-based resin, a polyamide-based resin, and a polyparaxylene-based resin.
[0085] Each of the first sensor conductive layer MTL1 and the second sensor conductive layer MTL2 may have a single-layer or multi-layer structure. A multi-layered sensor conductive layer may have two or more transparent conductive layers or metal layers. For example, a multi-layered sensor conductive layer may have a structure in which a transparent conductive layer and a metal layer are stacked, or metal layers including different metals are stacked.
[0086] The transparent conductive layer included in the first sensor conductive layer MTL1 and the second sensor conductive layer MTL2 may include indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium tin zinc oxide (ITZO), PEDOT, metal nanowires, graphene, etc. The metal layer included in the first sensor conductive layer MTL1 and the second sensor conductive layer MTL2 may include molybdenum, silver, copper, aluminum, or alloys thereof.
[0087] at the same time, Figure 3B The input sensor ISP is shown as including a stacked first sensor conductive layer MTL1 and a second sensor conductive layer MTL2, but embodiments are not limited thereto. For example, in embodiments, the input sensor ISP may include a single sensor conductive layer disposed on the sensor base layer ISL-B. In this case, one of the first sensor insulating layer ISL-C and the second sensor insulating layer ISL-T may be omitted.
[0088] When static electricity is generated by metal materials in the first and second sensor conductive layers MTL1 and MTL2, static electricity may be discharged. In this case, a portion of the sensor conductive layers MTL1 and MTL2 may be disconnected, or a connection portion where the sensor conductive layers MTL1 and MTL2 are connected to each other may burn.
[0089] Therefore, when a metal material or a charged material contacts or rubs against the top of the display module DM including the input sensor ISP, the display module DM is likely to be damaged. Therefore, when transporting the display module DM, a transport device and a transport method for effectively eliminating static electricity and not causing contact electrification are required.

Figure 4 and Figure 6 The ionizer INZ included in the transport unit TMU of the embodiment may include an irradiation unit SIP configured to directly irradiate with ions, and an irradiation control unit AGM configured to fix and change the direction of the irradiation unit SIP. The irradiation unit SIP and the irradiation control unit AGM of the ionizer INZ may be controlled and operated by the ionizer control unit CUN-1.
[0102] In the edge portion ED-INZ of the irradiation unit SIP, an emission hole HL-IZ from which ions are directly irradiated is provided. A plurality of emission holes HL-IZ may be defined in the edge portion ED-INZ.
[0103] Positive (+) ions may be emitted from some of the emission holes HL-IZ, and negative (-) ions may be emitted from other emission holes in the emission holes HL-IZ. Positive and negative ions may be irradiated simultaneously or alternately at intervals. This ion irradiation method is merely an example, and the operation type of the ion generator INZ is not limited to that described above.
[0104] Figure 7 An exemplary positional relationship between the mobile station MST and the ion generator INZ is shown. Figure 7 In FIG, X represents the moving direction of the mobile stage MST, and X-IZ represents the moving direction of the ionizer INZ. Figure 7 The ionizer INZ may be located on one side of the mobile stage MST on which the display module DM is mounted. In the conveying device of the embodiment, the first space SP between one side edge ED-DM of the display module DM and the ionizer INZ may be approximately 5 cm or longer. For example, in the conveying device of the embodiment, the first space SP between one side edge ED-DM of the display module DM and the ionizer INZ may be approximately 10 cm or longer. Specifically, in the conveying device of the embodiment, the first space SP between one side edge ED-DM of the display module DM and the ionizer INZ may be approximately 5 cm to approximately 50 cm.
[0105] In an embodiment, the first space SP may be a space between an edge of the pad area PDA and the ionizer INZ. In addition, in an embodiment, the first space SP may be a space between the emission hole HL-IZ of the ionizer INZ and one side edge ED-DM of the display module DM.
[0106] With the conveying device of the embodiment in which the position of the ionizer INZ is adjusted so that the first space SP is at least about 5 cm, electrification of the sensor conductive layer of the input sensor caused by ion contact irradiation can be prevented.
[0107] When the distance between one side edge ED-DM of the display module DM and the ionizer INZ is less than approximately 5 cm, an increase in the amount of ions directly irradiated on the display module DM may cause discharge in the sensor conductive layer of the input sensor included in the display module DM. Furthermore, when the distance between one side edge ED-DM of the display module DM and the ionizer INZ is greater than approximately 50 cm, the static elimination effect of the ionizer INZ may be reduced.
[0108] Table 1 shows the failure rate due to electrostatic discharge depending on the difference in spacing between the display module and the ionizer. The failure rate in Table 1 shows the failure rate due to damage to the input sensor. In Comparative Example 1, the display module was transported using a transport device in which the spacing between the ionizer and the display module was less than approximately 5 cm, and in Example 1, the display module was transported using a transport device according to an embodiment in which the spacing between the ionizer and the display module was at least approximately 5 cm.

[0111] When comparing Comparative Example 1 and Example 1, it can be understood that the failure rate of Example 1 is reduced by about 88% compared to Comparative Example 1. In other words, for Example 1 using the transmission device of the embodiment in which the space between the ion generator and the display module is at least about 5 cm, it can be understood that electrostatic discharge is reduced and the failure rate of the input sensor is significantly improved.
[0112] Figure 8 FIG. 1 shows a fixed mobile unit according to an embodiment. Figure 4 and Figure 8 , the fixed mobile unit FXM in the transport device TMU in the embodiment may include a pickup unit FP and a transport unit MP.
[0113] Each of the pickup units FP in the fixed moving unit FXM may include a vacuum suction unit MH and a pickup pad FPD. The vacuum suction unit MH may be defined with a suction hole HL (see Figure 9 Suction hole HL (see Figure 9 ) can be a through hole. The display module DM can be through the suction hole HL (see Figure 9 ) is adsorbed to be fixed using a vacuum state. However, the vacuum suction unit MH may not directly contact the display module DM, and the suction hole HL (see Figure 9 ) may be spaced apart from the top surface of the display module DM.
[0114] The pickup pad FPD may surround at least a portion of the vacuum suction unit MH. The pickup pad FPD may be a portion that directly contacts the display module DM.
[0115] Figure 9 is a perspective view of a pickup unit FP according to an embodiment of the present inventive concept. Figure 9 , the fourth direction DR4 is the opposite direction of the third direction DR3. Figures 10A to 10C Each shows a cross section of a pickup unit FP according to an embodiment. Figure 9 as well as Figures 10A to 10C, the pickup pad FPD may expose at least a portion of the suction hole HL and surround an edge portion of the vacuum suction unit MH.

However, embodiments of the inventive concept are not limited thereto.
[0117] according to Figure 10B The inner diameter W of the vacuum suction unit MH in the pickup unit FP-a of the embodiment shown in FIG. MH may be larger than the width W of the opening defined on the bottom of the pickup pad FPD PD2 , so as to surround the vacuum suction unit MH and be able to suck the display module DM. Figure 10C The inner diameter W of the vacuum suction unit MH in the pickup unit FP-b of the embodiment shown in FIG. MH may be substantially equal to the width W of the opening defined on the bottom of the pickup pad FPD PD3 , so as to surround the vacuum suction unit MH and be able to suck the display module DM.
[0118] exist Figure 9 as well as Figures 10A to 10C In the figure, the pickup pad FPD is shown as having a width that gradually widens from the top surface to the bottom surface in a cross-sectional view. However, this is merely an example, and the shape of the pickup pad FPD is not limited thereto. The shape of the pickup pad FPD is not particularly limited, as long as it allows the vacuum unit MH to secure and move the display module without directly contacting the display module and using the vacuum provided by the vacuum unit MH.
[0119] Figure 11 An example state in which the pickup unit is located on the display module is shown. Figure 12 An exemplary bottom portion of a pickup unit is shown. Figure 11 and Figure 12 The reference Figure 9 and Figure 10A The described embodiment uses the display module adsorption state of the pickup unit FP and the bottom surface shape of the pickup unit FP.
[0120] refer to Figure 11 and Figure 12 , the vacuum suction unit MH in the conveying device of the embodiment can be in the second space t SP The second space t is spaced apart from the top surface US-DM of the display module DM.SP The second space t may be at least about 3 mm. SP The upper limit value of is not particularly limited, and the second space t may be determined in consideration of whether the display module DM can be stably fixed and moved by the vacuum suction unit MH. SP That is, the second space t SP The upper limit value of may be determined according to the level of the vacuum state provided by the vacuum suction unit MH of the pickup unit FP.
[0121] The vacuum suction unit MH may be provided with a metal material. Therefore, when the vacuum suction unit MH and the display module DM become adjacent to each other by about 3 mm or less, electrostatic discharge may occur in the display module DM due to the vacuum suction unit MH.
[0122] Table 2 below shows a range of voltage at which electrostatic discharge occurs according to a space between the vacuum suction unit MH and the display module DM.
[0123] [Table 2]
[0124] Space (mm) 1 3 5 ESD voltage (V) 400 1500 100000
[0125] Referring to Table 2, when the vacuum suction unit MH and the display module DM are spaced at least about 3 mm apart and a voltage of at least about 1500 V is induced, electrostatic discharge may occur. Therefore, when the vacuum suction unit MH and the display module DM are spaced at least about 3 mm apart, the display module DM may be safely fixed and transferred using the pickup unit FP. When the pickup unit FP moves toward the display module DM and fixes the display module DM, the pickup pad FPD may be disposed to contact the top surface US-DM of the display module DM. The top surface US-DM of the display module DM in contact with the pickup pad FPD may be an input sensor ISP (see Figure 2 )side.

The bottom surface FPD-B of the pickup pad FPD may contact the top surface US-DM of the display module DM. The pickup pad FPD may surround at least a portion of the vacuum suction unit MH so that the vacuum suction unit MH does not directly contact the display module DM, and the space between the vacuum suction unit MH and the display module DM may be maintained by the pickup pad FPD.
[0127] The pickup pad FPD may include a polymer material. The surface resistivity of the pickup pad FPD may be at least about 10 12 Ω / sq. When the surface resistivity is at least about 10 12When the pickup pad FPD of Ω / sq is adsorbed onto the display module DM, electrification caused by the contact of the pickup pad FPD can be reduced, and electrostatic discharge failure caused by the contact of the pickup pad FPD can be reduced.
[0128] Table 3 shows the failure rate of electrostatic discharge according to the difference in surface resistivity value of the pickup pad. The failure rate in Table 3 shows the failure rate due to damage of the input sensor. Comparative Example 2 is a method using a device including a device having about 10 6 to about 10 9 Ω / sq, and Example 2 is a method for measuring the failure rate of display modules transferred by a transfer device of a pickup unit having a surface resistivity of at least about 10 Ω / sq. 12 The failure rate of the display modules transmitted by the transmission device of the embodiment of Ω / sq.
[0129] In Table 3, in both Comparative Example 2 and Example 2, failure rate comparison results were measured in a state in which the space between the vacuum suction unit in the pickup unit and the display module was equal to about 3 mm.
[0130] [Table 3]
[0131] category Comparative Example 2 Example 2 Failure rate (%) 9.92 4.24
[0132] When comparing Comparative Example 2 and Example 2, it can be understood that the failure rate of Example 2 is reduced by about 57% compared to Comparative Example 2. In other words, for a device using a substrate in which the surface resistivity of the pickup pad is at least about 10 12 As can be understood from the example 2 of the transmission device of the embodiment of Ω / sq, electrostatic discharge is reduced and the failure rate of the input sensor is significantly improved. Figure 8 The fixed moving unit FXM in the conveying device of the embodiment may include a plurality of pickup units FP. The plurality of pickup units FP may be fixed to the conveying unit MP to be moved simultaneously. The plurality of pickup units FP may be used to simultaneously convey a plurality of display modules DM.
[0133] Figure 13 The following are exemplary steps of a method of operating a conveying device according to an embodiment. Figure 13 The display module DM mounted on the mobile station MST can be moved from the mobile station MST using the pickup unit FP. The display module DM can be in a position where static electricity has been eliminated using an ionizer and has been inspected by the inspection unit ISU (see Figure 1 Here, the moving direction PD1 of the fixed moving unit including the pickup unit FP may be a direction for separating the display module DM from the mobile station MST.
[0134] The display module DM held by the pickup unit FP can then be transferred from the mobile station MST to the mobile unit TRU (see Figure 1 ). Figure 13 A transfer tray TR is shown as an exemplary moving unit. The moving direction PD2 of the fixed moving unit including the pickup unit FP may be a direction in which the display module DM is transferred toward the transfer tray TR.
[0135] The display module DM transported toward the transport tray TR can be placed on the transport tray TR, and then the pickup unit FP can be desorbed from the display module DM. The moving direction PD3 of the fixed moving unit including the pickup unit FP on the transport tray TR can be a direction adjacent to the transport tray TR or a direction spaced apart from the transport tray TR.
[0136] The display module DM transferred to the transfer tray TR may be manufactured into a display device through additional display device manufacturing processes. For example, after being transferred to the transfer tray TR, various processes may be performed, including a process for bonding optical components such as a polarizing plate to the display module DM, a process for attaching a driving circuit board, and a process for encapsulating the display module DM with a housing.
[0137] The conveying device of the embodiment may include a moving stage, an ion generator, and a fixed moving unit, and reduces the failure rate caused by static electricity by setting the space between the ion generator and the display module placed on the moving stage to at least about 5 cm and preventing static electricity discharge in the display module during ion contact irradiation. In addition, the conveying device of the embodiment may be configured to set the space between the vacuum suction unit in the fixed moving unit and the display module to at least about 3 mm and the surface resistivity of the pickup pad to at least about 10 12 Ω / sq to prevent electrostatic discharge due to contact of the fixed moving unit, and the fixed moving unit can be used to effectively transfer the display module.
[0138] Furthermore, the conveying device of the embodiment can reduce electrostatic discharge failures in display modules during the conveyance of display modules including input sensors. Specifically, for display modules having a medium or large display surface with a large area, a process can be employed in which a fixed moving unit is brought into direct contact with the top surface of the display module. In this case, even when the fixed moving unit is in direct contact, electrostatic failures can be minimized when conveying the display module using the conveying device of the embodiment.

Figure 1 ). It is possible to move to the inspection unit ISU (see Figure 1 ) is inspected to determine normal operation, appearance quality, etc., and then transferred to the mobile unit TRU (see Figure 1 ). In addition, the display module can be checked to determine whether a fault has occurred and then the transmission device can be used to transmit the fault information to the ion processing unit ITU (see Figure 1 ) is transmitted to the mobile unit TRU (see Figure 1 ).
[0148] The step S500 of moving the display module from the moving stage may include a step S510 of bringing a fixed moving unit close to the display module, a step S530 of fixing the display module to the fixed moving unit, and a step S550 of transferring the display module from the moving stage to a transfer tray.
