[0151] The first moving part MV1 may be connected to the third driving part DV3 in the first direction DR1, and thus may be movable in the first direction DR1. For example, the third driving rod DB3 may be disposed between the third driving part DV3 and the first moving part MV1, and may be connected to the third driving part DV3 and the first moving part MV1. Although not shown in the drawings, the third driving rod DB3 may extend into the third driving part DV3 and be connected to the motor inside the third driving part DV3. The third driving rod DB3 may extend from the third driving part DV3 in the first direction DR1, and thus may be connected to the first moving part MV1.

[0152] The third driving portion DV3 may move the first moving portion MV1 in the first direction DR1. For example, when the third driving portion DV3 moves the third driving rod DB3 in the first direction DR1, the first moving portion MV1 may also move in the first direction DR1.

When the second moving part MV2 moves in the third direction DR3 through the third driving part DV3, the nozzle driving part NDV connected to the second moving part MV2 can also move in the third direction DR3. In addition, the nozzle NZ connected to the nozzle driving part NDV can also move in the third direction DR3.

[0201] According to the operation of the third driving part DV3 to move the second moving part MV2, the nozzle driving part NDV and the nozzle NZ can move in the third direction DR3. Therefore, the rotation driving part RDV, the curved track part CRA, the curved moving part CMP and the nozzle NZ can basically move in the third direction DR3 by the third driving part DV3.

[0204] Fig.23 A cross section of the display panel DP when viewed from the second direction DR2 is exemplarily shown.

[0205] refer to Fig.23 , the display panel DP according to the embodiment of the present invention may be an emissive display panel, and is not particularly limited thereto. For example, the display panel DP may be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material. The light-emitting layer of the quantum dot light-emitting display panel may include quantum dots, quantum rods, etc. Hereinafter, the display panel DP is described as an organic light-emitting display panel.

[0206] The display panel DP may include a lower substrate L-SB, an upper substrate U-SB, and a light blocking layer LSL, wherein the upper substrate U-SB is disposed on the lower substrate L-SB, and the light blocking layer LSL is disposed on a surface near where the lower substrate L-SB meets the upper substrate U-SB.

[0208] The lower substrate L-SB may include a display area DA and a non-display area NDA surrounding the display area DA. The light emitting element layer OL may be disposed in the display area DA.

[0209] The encapsulation substrate EN-SB may be disposed on the light emitting element layer OL. The sealing layer SAL may be disposed between the lower substrate L-SB and the encapsulation substrate EN-SB. The sealing layer SAL may be disposed in the non-display area NDA. The sealing layer SAL may combine the lower substrate L-SB and the encapsulation substrate EN-SB together. The light emitting element layer OL may be sealed between the lower substrate L-SB and the encapsulation substrate EN-SB by the sealing layer SAL.

[0210] The filler FL may be disposed between the lower substrate L-SB and the encapsulation substrate EN-SB. The filler FL may be disposed between the lower substrate L-SB and the encapsulation substrate EN-SB in a space sealed by the sealing layer SAL.

[0211] The upper substrate U-SB may have a width smaller than that of the lower substrate L-SB. The width may be defined as a value measured in the first direction DR1 or in the second direction DR2. The width of the upper substrate U-SB and the width of the lower substrate L-SB are different from each other, and thus an edge of the lower substrate L-SB and an edge of the upper substrate U-SB may form a step.

[0212] The edge of the display panel DP may be defined as a step portion STP between the edge of the lower substrate L-SB and the edge of the upper substrate U-SB. The light blocking layer LSL may be disposed on the step portion STP. The light blocking layer LSL may have a black color for blocking light.

[0213] The light generated in the light emitting element layer OL may leak to the outside through the step portion STP. This phenomenon is sometimes referred to as a "light leakage phenomenon". The light blocking layer LSL may block the light generated in the light emitting element layer OL from leaking through the step portion STP. That is, the light blocking layer LSL may be used to prevent the light leakage phenomenon. The light blocking layer LSL may be formed by Figures 1 to 3 The distributing device DPA shown in FIG. 1 is provided on the step portion STP.

[0214] FIG. 24A to FIG. 24C is a diagram illustrating a method of forming a light blocking layer LSL using a dispensing apparatus DPA according to an embodiment of the inventive concept.

[0215] FIG. 24A to FIG. 24C The nozzle NZ is shown in a simplified form in contrast to the previous figures.

[0216] refer to Fig.24A , the nozzle NZ may be disposed adjacent to the side surface of the display panel DP extending in the second direction DR2. Thereafter, an alignment process of the nozzle NZ may be performed such that the nozzle NZ proceeds toward the step portion STP.

[0217] The nozzle NZ may be aligned according to the operations of the aforementioned first driving part DV1, the second driving part DV2, and the third driving part DV3. For example, when the nozzle NZ is disposed toward the side surface of the display panel DP parallel to the second direction DR2, the nozzle NZ may be moved in the first direction DR1 by the first driving part DV1, and the nozzle NZ may be moved in the third direction DR3 by the third driving part DV3. According to these operations, the nozzle NZ may be disposed toward the step part STP. The nozzle NZ may discharge the resin RIN toward the step part STP.

[0218] refer to Fig.24A and Fig. 24B , the resin RIN may be supplied to each target point (not shown) of the step portion STP. The nozzle NZ may discharge the resin RIN toward each target point of the step portion STP a plurality of times.

[0219] For example, Fig.24A As shown in , the nozzle NZ may be disposed in a first inclined direction SDR1 defined at a predetermined angle relative to the top surface of the lower substrate L-SB so that the resin RIN may be provided to the step portion STP. Thereafter, the nozzle NZ may be rotated relative to the tip of the nozzle NZ by the aforementioned nozzle driving portion NDV, and thus may be disposed in a second inclined direction SDR2 different from the first inclined direction SDR1. Therefore, the nozzle NZ may be disposed in the second inclined direction SDR2, as shown in FIG. Fig. 24B As shown in , the resin RIN can be supplied to the step portion STP.

[0220] refer to Fig.24C , the nozzle NZ may be disposed adjacent to the side surface of the display panel DP extending in the first direction DR1. In this case, the nozzle NZ may be moved in the second direction DR2 by the second driving part DV2, and the nozzle NZ may be moved in the third direction DR3 by the third driving part DV3. According to these operations, the nozzle NZ may be directed to the step part STP. Thereafter, the same operation as reference may be performed. Fig.24A and Fig. 24B The process described is similar to the resin discharge process.

[0221] Although not shown in the drawings, the nozzle NZ may be Fig.24A The state in which the nozzle NZ is disposed adjacent to the side surface of the display panel DP extending in the second direction DR2 shown in FIG. 1 is changed to Fig.24C In the state shown in FIG. 1 , the nozzle NZ is disposed adjacent to the side surface of the display panel DP extending in the first direction DR1. In this case, the nozzle NZ can be rotated about 90° around a rotation axis parallel to the third direction DR3, and this operation can be performed according to a rotation operation of the rotation head RH relative to the aforementioned head rotation axis HRX.

[0222] Fig.25A and Fig.25B : is a diagram illustrating a method of forming the light blocking layer LSL using the nozzle NZ' of the dispensing device according to the comparative example.

[0223] refer to Fig.25A , the resin RIN may be supplied to the step portion STP through the nozzle NZ′ disposed in the first oblique direction SDR1.

[0224] refer to Fig.25B , the nozzle NZ' may rotate around the rotation axis RX' that coincides with the central portion of the nozzle NZ' instead of around the tip of the nozzle NZ'. When the nozzle NZ' rotates around the rotation axis RX' so as to change the direction of the nozzle NZ' to the second inclined direction SDR2, the position of the tip of the nozzle NZ' that discharges the resin RIN may change. Therefore, in order to align the position of the lower end portion of the nozzle NZ' back to Fig.25A The initial state shown in FIG. 1 may require additional processing.

[0225] However, according to an embodiment of the inventive concept, the nozzle driving portion NDV may rotate the nozzle NZ relative to the lower end of the nozzle NZ discharging the resin RIN, thereby aligning the nozzle NZ. Therefore, the aligning operation of the nozzle NZ may be performed more easily.

[0226] Fig.26 is a diagram of a nozzle NZ-1 according to another embodiment of the present inventive concept. Fig. 27 yes Fig.26 The nozzle NZ-1 is shown in the diagram.

[0227] Fig.26 is exemplarily shown with Fig.17 Corresponding side view. In the following, Figure 26 to Figure 31 It is shown that the first direction DR1, the second direction DR2, and the third direction DR3 are fixed, and the position of the nozzle NZ-1 is variously changed.

The nozzle NZ-1 may be connected to the curved moving part CMP through the nozzle connecting part NCP. The nozzle NZ-1 may be defined as a discharge device. Hereinafter, the nozzle NZ-1 is referred to as a discharge device.

[0229] The discharge device NZ-1 may be connected to the second nozzle connection part NCP2. Like the aforementioned nozzle NZ, the discharge device NZ-1 may be arranged to be inclined toward the first direction DR1 and may be rotated relative to the tip of the discharge device NZ-1.

The connection portion CT may be connected to the second nozzle connection portion NCP2. Therefore, the discharge device NZ-1 may be connected to the bending moving portion CMP through the connection portion CT and the nozzle connection portion NCP.

[0233] As mentioned above, the rotation axis RX may coincide with the tip of the discharge portion DSP. According to the operation of the bending movement portion CMP, the discharge device NZ-1 may rotate relative to the lower end of the discharge portion DSP.

[0234] Fig.28 It is set to be parallel to the third direction DR3. Fig.26 A side view of the discharge device NZ-1 shown in FIG. Fig.29 is rotated around the third direction DR3 to show Fig.28 FIG. 1 is a diagram of a discharge device NZ-1 showing a side surface of the ink inlet tube IIT. Fig.30 The conductive part CTP is removed from it, Fig.29 A side view of the discharge device NZ-1 shown in FIG.

[0235] exist Fig.28 In the figure, the stage STG disposed below the discharge device NZ-1 is exemplarily shown together with the discharge device NZ-1. For the convenience of description, Fig.28 The stage STG and the display panel DP are shown to be relatively smaller than the discharge device NZ-1. In addition, the control part CON, the voltage generating part VG, the stage STG and the display panel DP are only Fig.28 is shown in Fig.29 and Fig.30 is omitted.

[0236] refer to Fig.28 , Fig.29 and Fig.30 , the aforementioned dispensing device DPA may further include a control part CON, a voltage generating part VG and a stage STG. The discharging device NZ-1 may further include a cable connecting part CCB provided on the driving part DV. The control part CON may be connected to the cable connecting part CCB via a cable (not shown). The cable connecting part CCB may be connected to the driving part DV.

[0237] The control part CON may be connected to the driving part DV, for example, via a cable and a cable connection part CCB, and may control the operation of the driving part DV. For example, the driving part DV may include a motor, and the control part CON may control the revolutions per minute (RPM) of the motor. The motor may rotate around a rotation axis parallel to the extension direction (or length direction) of the discharge device NZ-1. Figures 28 to 30 In the embodiment of the present invention, the extension direction of the discharge device NZ-1 is the third direction DR3.

[0238] exist Fig.28 In the embodiment, the driving portion DV, the first and second shells CS1 and CS2, the insulating portion INP, the ink conveying portion IMV, and the discharge portion DSP may be arranged in the extending direction of the discharge device NZ-1. Fig.28 In the embodiment, the driving portion DV, the first and second housings CS1 and CS2, the insulating portion INP, the ink conveying portion IMV, and the discharge portion DSP may be arranged in the third direction DR3.

[0239] The discharge portion DSP may be disposed below the driving portion DV, the first housing CS1 and the second housing CS2, the insulating portion INP and the ink conveying portion IMV, and the ink conveying portion IMV may be disposed between the driving portion DV and the discharge portion DSP. The first housing CS1 may be disposed between the driving portion DV and the insulating portion INP. The insulating portion INP may be disposed between the first housing CS1 and the second housing CS2.

[0240] The ink inlet tube IIT may be connected to a side surface of the second housing CS2. The second housing CS2 may be disposed between the insulating portion INP and the ink conveying portion IMV. The ink conveying portion IMV may be disposed between the second housing CS2 and the discharge portion DSP.

[0241] The conductive portion CTP may be disposed to surround the ink conveying portion IMV and be connected to the ink conveying portion IMV. The conductive portion CTP may be disposed to surround the lower portion of the ink conveying portion IMV, and thus may be disposed adjacent to the discharge portion DSP. However, the position of the conductive portion CTP is not limited thereto, and for example, the conductive portion CTP may also be connected to the discharge portion DSP. For example, the conductive portion CTP may include a conductive metal material.

[0242] The stage STG may be disposed under the discharge portion DSP. The stage STG may have a flat surface defined by the first direction DR1 and the second direction DR2. The display panel DP may be placed on an upper surface of the stage STG. The display panel DP may be a process object.

[0243] The voltage generating part VG may be connected to the control part CON. The control part CON may control the level of the voltage generated from the voltage generating part VG. The voltage generating part VG may generate a voltage of 1 kV to 4 kV. The voltage generating part VG may apply a high voltage of 1 kV to 4 kV to the conductive part CTP, and apply a ground voltage to the stage STG. That is, the stage STG may be grounded. Therefore, an electric field may be formed from the conductive part CTP toward the stage STG.

[0244] The driving power of the driving part DV (e.g., the rotational power of the motor) may be transmitted to the ink conveying part IMV. The ink may flow into the ink inlet tube IIT. Although not shown in the drawings, the ink inlet tube IIT may be connected to the ink storage part and may receive the ink from the ink storage part. The ink may be supplied to the ink conveying part IMV, and the ink may be supplied to the discharge part DSP according to the driving power transmitted to the ink conveying part IMV. These internal configurations and operations will be referred to Fig.31 describe.

[0245] According to this operation, the discharge part DSP may discharge the ink according to the driving power of the driving part DV. The discharge part DSP may discharge the ink toward the display panel DP. In the process of manufacturing the display panel DP, a specific method of providing the ink to the display panel DP will be referred to. FIG. 34A to FIG. 34D The detailed description is as follows.

[0246] As described above, since a high voltage is applied to the conductive portion CTP, an electric field may be formed from the conductive portion CTP toward the stage STG. In this case, due to the electric field, ink may be easily supplied to the display panel DP on the stage STG. The conductive portion CTP may also be omitted. In this case, the discharge portion DSP may include a conductive metal material, and the voltage generating portion VG may apply a voltage to the discharge portion DSP.

[0247] According to an embodiment of the inventive concept, ink may be more easily provided to the display panel DP due to the power of the electric field formed by the voltage applied to the conductive portion CTP and the driving power of the driving portion DV.

[0248] The insulating portion INP may include an insulating material such as plastic. The insulating portion INP may block any current that may flow from the conductive portion CTP to the driving portion DV according to the voltage applied to the conductive portion CTP. When current flows into the driving portion DV, the driving portion DV may be damaged or malfunction due to the high voltage applied to the conductive portion CTP. Since the insulating portion INP blocks the current that may flow from the conductive portion CTP to the driving portion DV, damage and malfunction of the driving portion DV may be prevented.

[0249] Fig.31 It is schematically shown Fig.28 FIG. 4 is a diagram of the internal configuration of the discharge device NZ-1 shown in FIG.

[0250] For ease of description, Fig.31 The external shape of the discharge device NZ-1 and the part of the internal structure related to the driving power are shown.

[0251] refer to Fig.31 , the discharge device NZ-1 may include a drive shaft DSFT disposed below the drive portion DV. The ink conveying portion IMV may include a rotor ROT and a stator SAT.

[0252] The drive shaft DSFT may be disposed in the first and second housings CS1 and CS2 and the insulating portion INP. The drive shaft DSFT may be disposed between the drive portion DV and the discharge portion DSP. The drive shaft DSFT may be connected to the drive portion DV and extend toward the discharge portion DSP. The rotor ROT may be disposed between the drive shaft DSFT and the discharge portion DSP. The rotor ROT may be connected to the drive shaft DSFT and extend toward the discharge portion DSP.

[0253] When the driving part DV rotates, the driving power of the driving part DV (e.g., the rotational power of the motor) can be transmitted to the driving shaft DSFT. In addition, the driving power of the driving part DV can be transmitted to the rotor ROT through the driving shaft DSFT. Therefore, the driving shaft DSFT and the rotor ROT can be rotated by the driving part DV.

[0254] The hollow CVT passing through the stator SAT in the third direction DR3 may be defined inside the stator SAT. The rotor ROT may be inserted into the hollow CVT defined inside the stator SAT, and thus may be disposed inside the hollow CVT. The inner circumferential surface of the hollow CVT may have a single-stage female thread shape or a multi-stage female thread shape. The outer circumferential surface of the rotor ROT may have a single-stage male thread shape or a multi-stage male thread shape corresponding to the inner circumferential surface of the stator SAT.

[0255] When the rotor ROT is disposed in the hollow CVT of the stator SAT, the transfer space MSC may be defined along the extension direction of the discharge device NZ- 1. The transfer space MSC may be defined between the inner circumferential surface of the stator SAT and the rotor ROT.

[0256] Ink (not shown) may flow into the second case CS2 through the ink inlet tube IIT to be disposed in the transfer space MSC. The driving shaft DSFT may rotate according to the driving power of the driving portion DV, and the rotor ROT may rotate according to the rotation of the driving shaft DSFT.

[0257] The rotor ROT may eccentrically rotate in the hollow CVT of the stator SAT, and thus may transfer the ink disposed in the transfer space MSC to the lower portion. Thus, the ink may be supplied to the discharge portion DSP, and the discharge portion DSP may discharge the ink. Thus, the discharge portion DSP may discharge the ink according to the driving power of the driving portion DV.

[0258] As the rotation power of the driving part DV becomes larger, that is, as the number of revolutions per minute becomes larger, the driving shaft DSFT and the rotor ROT can rotate faster, and more ink can be supplied to the discharge part DSP. Since the control part CON controls the rotation power of the driving part DV as described above, the amount of ink discharged from the discharge part DSP can be controlled.

Fig.35B The discharge amount of ink discharged from the discharge device NZ-1 according to an embodiment of the inventive concept according to the rotations per minute of the driving portion DV is shown.

[0291] Hereinafter, the driving portion DV of the discharge device NZ-1 according to an embodiment of the inventive concept will be referred to as a motor.

[0292] exist Fig.35A In FIG. 1 , the horizontal axis represents pressure, and the vertical axis represents the discharge amount of ink. Fig.35B , the horizontal axis represents the number of revolutions per minute (RPM) of the motor, and the vertical axis represents the discharge amount of ink. The unit of pressure is kilopascal (kPa), and the unit of discharge amount is milligram (mg).

[0293] refer to Fig.35A and Fig.35B , the pneumatic type, which is the same as the syringe, can be defined as a type that discharges ink by pushing the ink out under pressure. The discharge device NZ-1 according to an embodiment of the inventive concept can be defined as a motor type that discharges ink by using a motor, and therefore can also be called an electric discharge device NZ-1. In addition, the discharge device NZ-1 according to an embodiment of the inventive concept can discharge ink by forming the aforementioned electric field.

[0294] In the case of the pneumatic type, the discharge amount of ink may increase as the pressure increases. In the case of the motor type, the discharge amount of ink may increase according to the increase in the number of revolutions per minute of the motor. The discharge amount of ink in the motor type may be greater than that in the pneumatic type.

[0295] The pneumatic discharge device and the electric discharge device NZ-1 according to an embodiment of the present invention can discharge ink while moving. When the pneumatic discharge device and the electric discharge device NZ-1 according to an embodiment of the present invention move at the same speed, the discharge amount of ink of the electric discharge device NZ-1 according to an embodiment of the present invention can be 1.5 to 3 times the discharge amount of ink of the pneumatic discharge device.

[0296] When the pneumatic discharge device and the electric discharge device NZ-1 according to an embodiment of the present inventive concept discharge the same amount of ink, the moving speed of the electric discharge device NZ-1 according to an embodiment of the present inventive concept may be higher than that of the pneumatic discharge device.

[0301] refer to Fig.36A and Fig.36B , in the case of motor types, the increases can be approximately similar to each other, and as Fig.36B As shown in , the discharge amount of ink can be increased approximately linearly. However, in the case of the pneumatic type, the increase amount may not be constant compared to the motor type, so that Fig.36B As shown in , the amount of ink discharged may not increase linearly.

[0302] When the discharge amount of ink increases linearly, the discharge amount of ink can be easily controlled. That is, since the discharge amount of ink increases linearly according to the increase in the rpm of the motor, the discharge amount of ink can be easily predicted according to the rpm of the motor. Therefore, according to an embodiment of the inventive concept, by controlling the rpm of the motor, the discharge amount of ink can be easily controlled.

[0309] According to an embodiment of the inventive concept, a nozzle driving portion of a dispensing device may rotate the nozzle relative to a tip of the nozzle from which the resin is discharged, thereby aligning the nozzle. Therefore, an aligning operation of the nozzle may be performed more easily.
