[0002] In near-eye display devices such as VR display devices (Virtual Reality) and AR (Augmented Reality), OLED display panels (Organic Light-Emitting Diode) are usually used as display devices. In order to increase the luminous brightness of the display device, microlenses are added to the OLED display panel, and the microlens offset technology is used to make the light-emitting structure of some pixels eccentric to the microlens to avoid the problem of light path distortion.

[0003] At present, the most common defect in display devices is the bright spot defect, which can be repaired by destroying the bright spot of the pixel with a laser. However, for display panels that use microlens offset technology, the laser will be affected by the refraction of the microlens when it is incident on the display panel, which can easily cause the laser to deviate from the position of the damaged part and deviate from the bright spot to be repaired, resulting in accidental injury or repair failure, affecting the success rate of the repair. Summary of the invention

[0010] The rotating assembly and the carrying platform are arranged on the swing table, and the swing table can slide along the sliding surface to drive the rotating assembly and the carrying platform to swing relative to the base.

[0013] In one embodiment, the carrying platform can be raised and lowered along the normal direction of the carrying surface.

[0014] The present invention further provides a pixel bright spot repair system, comprising a laser and a display panel carrier as described in any of the aforementioned embodiments.

[0015] The present invention further provides a pixel bright spot repair method, which is implemented by using the above-mentioned pixel bright spot repair system, and the pixel bright spot repair method comprises the following steps:

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In near-eye display devices such as VR display devices (Virtual Reality) and AR (Augmented Reality), OLED display panels (Organic Light-Emitting Diode) are usually used as display devices. In order to increase the luminous brightness of the display device, microlenses are added to the OLED display panel, and the microlens offset technology is used to make the light-emitting structure of some pixels eccentric to the microlens to avoid the problem of light path distortion.

[0044] Please refer to Figure 1 and Figure 2 The display panel 200 includes a substrate 250, a light emitting layer 210 and a microlens layer 220 which are stacked in sequence. The light emitting layer 210 is provided with a plurality of light emitting structures 240. The microlens layer 220 includes a plurality of microlenses 260 corresponding to each light emitting structure 240. The light emitting structure 240 and the corresponding microlens 260 form a pixel. In some embodiments, a filter layer 230 is further provided in the display panel 200. The filter layer 230 includes a plurality of filter structures 270 corresponding to the plurality of light emitting structures 240. The filter structure 270 is located between the light emitting structure 240 and the microlens 260. The pixel located at the center of the display area of ​​the display panel 200 is the center pixel. The light emitting angle of the center pixel is the same as the normal direction of the display panel 200. The light emitting center of the light emitting structure 240 of the center pixel is coaxial with the lens center of the microlens 260. The other pixels of the pixel panel are edge pixels. In order to adapt to the distortion of the light path after the silicon-based OLED is matched with the near-eye display optical module, the light-emitting center of the light-emitting structure 240 of the edge pixel is offset from the lens center of the microlens 260. The offset direction is the direction of the line connecting the edge pixel and the center pixel. With this setting structure, the edge pixel is affected by the refraction of the microlens 260. The light path of the edge pixel is oblique to the normal direction of the display panel 200, and the light emitting angles of the edge pixels at different positions are different. The farther the edge pixel is from the center pixel, the larger the light emitting angle. Define the intersection of the light path of the center pixel and the reverse extension line of the light path of the pixel 280 to be repaired as S, such as Figure 2 As shown, the emission light model of the display panel 200 can be regarded as a light emitting model with point S as the cone center.

[0045] When a bright spot defect appears in the display panel 200, a laser repair method can be used to use a laser to destroy the light emitting structure 240 of the pixel 280 to be repaired so that the pixel no longer emits light and forms a dark pixel. If the pixel with a bright spot defect is a central pixel, since the light emitting structure 240 and the microlens 260 of the central pixel are not offset, the laser is incident along the normal direction of the display panel 200, and the laser incident angle is the same as the light emitting angle of the central pixel, and can accurately be directed to the light emitting structure 240 of the central pixel. If the pixel with a bright spot defect is an edge pixel, since the light emitting structure 240 and the microlens 260 of the edge pixel are offset, if the laser is incident vertically along the normal direction of the display panel 200, it will be affected by the refraction of the microlens 260, and the laser will be deflected, resulting in the position where the laser actually incidents on the light emitting layer 210 being offset from the position to be repaired, which is prone to accidentally damaging other structures or repair failure.

[0046] Based on the above problems, the present invention proposes a display panel carrier 100 , which can be applied in a pixel bright spot repair system for repairing bright spots on a display panel 200 . The display panel carrier 100 is used to carry the display panel 200 .

[0047] Combined with reference Figure 3 and Fig.10 In one embodiment of the present invention, the display panel carrier 100 includes a carrying platform 1 and a deflection assembly 2. The carrying platform 1 is provided with a carrying surface 11 for carrying the display panel 200; the deflection assembly 2 is transmission-connected to the carrying platform 1 for driving the carrying platform 1 to swing.

[0048] In the embodiment of the present application, the laser is vertically emitted downward to the display panel 200 for laser repair as an example for orientation description. It is understandable that in different use environments, the laser can also be emitted horizontally or at other angles, and the installation orientation of the display panel carrier 100 is also adjusted accordingly.

[0049] The display panel carrier 100 provided by the present invention can adjust the tilt angle of the display panel 200 to adjust the tilt angle of the display panel 200 according to the light emitting angle of the pixel point 280 to be repaired, so that the light emitting direction of the pixel point 280 to be repaired coincides with the incident direction of the laser. In this way, when performing laser repair, the laser is emitted to the light emitting position of the pixel point 280 to be repaired, and can be emitted to the light emitting structure 240 of the pixel point 280 to be repaired along the light emitting path, so as to break down and destroy the light emitting structure 240, so that the pixel bright spot becomes a pixel dark spot and no longer emits light.

[0050] Specifically, the display panel carrier 100 includes a carrying platform 1 for placing the display panel 200, and the carrying platform 1 is formed with a carrying surface 11, and the display panel 200 can be placed on the carrying surface 11. The display panel carrier 100 is defined to have an initial state, in which the carrying surface 11 of the carrying platform 1 is perpendicular to the laser incident direction. Optionally, an air duct for connecting a vacuum generator can be provided on the carrying platform 1, and the carrying surface 11 is provided with adsorption holes connected to the air duct, and the display panel 200 is fixed on the carrying surface 11 by vacuum adsorption. In addition, the display panel 200 can also be pressed onto the carrying surface 11 using a mask plate.

[0051] The deflection assembly 2 is used to drive the carrying platform 1 to swing, so as to adjust the tilt state of the carrying platform 1 and thus adjust the tilt angle of the display panel 200. The deflection assembly 2 can be set as a motor, the motor is located on one side of the carrying platform 1, and the output shaft of the motor is connected to the carrying platform 1, and the output shaft is driven to rotate to control the swing of the carrying platform 1; the deflection assembly 2 can also include a motor and a transmission mechanism, the transmission mechanism can be a gear transmission structure, a belt transmission structure, a connecting rod transmission structure, a worm gear transmission structure or other structures, and the motor is connected to the carrying platform 1 through the transmission mechanism to drive the carrying platform 1 to swing; in addition, a swing table 22 that can slide along the concave arc surface can also be set in the following embodiment for setting the carrying platform 1, which is not limited here.

[0052] Optionally, the deflection assembly 2 can drive the supporting platform 1 to swing in one direction. In this case, a rotating assembly can be set in the following embodiment to drive the supporting platform 1 to rotate, so as to move the pixel point 280 to be repaired to be in the same plane as the light emitting direction and the swinging direction. In addition, in some embodiments, a combination of at least two deflection structures or a universal swing structure can be set to achieve driving the supporting platform 1 to swing in at least two directions, so that the repaired pixel points located at different positions around the central pixel point can be adjusted to the same light emitting angle as the laser incident angle.

[0053] Optionally, the laser light path can be directed toward the pixel point 280 to be repaired by translating the laser, or, as in the following embodiment, a first slide 4 and a second slide 5 can be set in the display panel carrier 100 to drive the carrying platform 1 to move and adjust the position of the display panel 200 so that the pixel point 280 to be repaired is moved to the laser incident position.

[0054] That is, the technical solution of the present invention makes the tilt angle of the display panel 200 arranged on the carrying platform 1 adjustable by setting the deflection component 2 for adjusting the tilt angle of the carrying platform 1. When it is necessary to repair the bright spot of the pixel in the display panel 200, by adjusting the tilt angle of the carrying platform 1 and the display panel 200, the light emitting direction of the pixel point 280 to be repaired is adjusted to coincide with the incident direction of the laser, and the laser can be accurately emitted on the light emitting structure 240 of the pixel point 280 to be repaired, so as to accurately destroy the light emitting structure 240 of the pixel point 280 to be repaired and make the pixel point a dark spot; this repair method can avoid the problem of damage position offset due to the refraction of the microlens 260, and improve the success rate of laser repair.

[0055] Combined with reference Figure 3 , Figure 7 and Figure 8 In one embodiment, the display panel carrier 100 also includes a rotating component, the carrying platform 1 is arranged on the rotating component, the rotating component is transmission-connected to the yaw component 2, the yaw component 2 can drive the rotating component and the carrying platform 1 to swing, and the rotating component can drive the carrying platform 1 to rotate along the plane where the carrying surface 11 is located.

[0056] In the display panel 200, the light emitting directions of the edge pixels at different positions around the central pixel are different. If the light emitting direction of the pixel 280 to be repaired is not in the same plane as the swing direction of the supporting platform 1, the light emitting direction of the pixel 280 to be repaired cannot be adjusted to coincide with the incident direction of the laser. In this embodiment, through the setting of the rotating component, the supporting platform 1 can be driven to rotate by the rotating component to drive the display panel 200 to rotate, thereby adjusting the light emitting direction of the pixel 280 to be repaired to be in the same plane as the swing direction of the deflection component 2, and then driving the rotating component to swing can drive the supporting platform 1 to swing until the light emitting direction of the pixel 280 to be repaired in the display panel 200 is adjusted to coincide with the incident direction of the laser.

[0057] Optionally, the cooperation method between the rotating component and the carrying platform 1 can be that the carrying platform 1 is set on the rotating platform 3 of the rotating component; or gear teeth are set on the edge of the carrying platform 1, and the rotating component can be set with a gear or rack that meshes with the carrying platform 1, or a synchronous belt or other structure is set to be connected to the carrying platform 1, so as to drive the carrying platform 1 to rotate.

[0058] Optionally, the deflection assembly 2 can drive the rotating assembly and the carrying platform 1 to swing synchronously. The deflection assembly 2 can drive the carrying platform 1 to swing by driving the rotating assembly to swing, or the deflection assembly 2 can be simultaneously connected to the rotating assembly and the carrying platform 1 to drive the rotating assembly and the carrying platform 1 to swing synchronously.

[0059] Combined with reference Figure 3 and Fig.10In one embodiment, the deflection and swing assembly 2 includes a base 21 and a swing table 22, at least a portion of the top surface of the base 21 is a sliding surface 211, the sliding surface 211 is set as a concave arc surface or a concave spherical surface, the swing table 22 is attached to the sliding surface 211, the rotating assembly and the supporting platform 1 are arranged on the swing table 22, and the swing table 22 can slide along the sliding surface 211 to drive the rotating assembly and the supporting platform 1 to swing relative to the base 21.

[0060] In this embodiment, the sliding surface 211 on the top surface of the base 21 can be set as a concave arc surface, and the swing table 22 is provided with a convex arc surface that matches and fits the concave arc surface, and the swing table 22 can slide along the concave arc surface to deflect relative to the base 21; or, the sliding surface 211 can be set as a concave spherical surface, in which case the swing table 22 can swing universally relative to the base 21. The combination structure of the base 21 and the swing table 22 is used to form the deflection assembly 2 for supporting the bearing platform 1, which can not only improve the support stability of the bearing platform 1, but also the stacking arrangement of the deflection assembly 2 and the bearing platform 1 can also reduce the installation area of ​​the display panel carrier 100. Optionally, a gear may be provided in the base 21, the gear being exposed on the sliding surface 211 and meshing with the swing table 22, and the swing table 22 being driven to slide along the sliding surface 211 by driving the gear to rotate; a motor may also be provided on the side of the swing table 22, and the swing table 22 may be directly driven by the motor to move relative to the base 21. Of course, other transmission structures may also be used to drive the swing table 22 to slide along the sliding surface 211, which is not limited here.

[0061] Optionally, the carrying platform 1 can be directly set on the swing table 22, or on other structures installed on the swing table 22. For example, the carrying platform 1 can be set on a rotating component, or on the second slide 5 in the following embodiment, which is not limited here.

[0062] Combined with reference Figure 7 and Figure 8 In one embodiment, the swing table 22 is provided with a mounting surface, the rotating assembly includes a rotating platform 3 rotatably provided on the mounting surface, and the carrying platform 1 is provided on the rotating platform 3 .

[0063] In this embodiment, the rotating assembly includes a rotating platform 3, which is rotatably arranged on the mounting surface of the swing table 22. The carrying platform 1 can be directly arranged on the rotating platform 3, or can be arranged on a slide arranged on the rotating platform 3 as in the following embodiment. The rotating platform 3 can drive the carrying platform 1 to rotate, and the rotating platform 3 can swing relative to the base 21 with the swing table 22. Optionally, a motor or other driving structure for driving the rotating platform 3 to rotate can be arranged in the swing table 22, or the driving structure can be arranged outside the swing table 22, which is not limited here.

[0064] Combined with reference Figure 3 , Figure 5 and Figure 7In one embodiment, the display panel carrier 100 also includes a first slide 4 and a second slide 5, the first slide 4 is slidably disposed on the top surface of the rotating platform 3, the second slide 5 is slidably disposed on the top surface of the first slide 4, the carrying platform 1 is disposed on the second slide 5, and the sliding directions of the first slide 4 and the second slide 5 are set at an angle.

[0065] In this embodiment, the display panel carrier 100 includes a first slide 4 and a second slide 5 for driving the carrying platform 1 to translate along the direction of the carrying surface 11. The first slide 4 is slidably arranged on the rotating platform 3, and the second slide 5 is slidably arranged on the first slide 4, so that the second slide 5 can drive the carrying platform 1 to slide relative to the first slide 4, and the first slide 4 can drive the second slide 5 and the carrying platform 1 to slide relative to the deflection component 2. In this way, the relative position of the carrying platform 1 is adjusted by the first slide 4 and the second slide 5, so that the display panel 200 moves and the position of the pixel point 280 to be repaired is adjusted.

[0066] In specific applications, the incident light path of the laser and the swing center axis of the swing table 22 are located in the same plane. When the display panel 200 is installed on the bearing surface 11, the display panel 200 and the laser light path are perpendicular to each other, and the central pixel point of the display panel 200 is at the laser incident position, which is the initial state. The position of the pixel point 280 to be repaired is determined, and the pixel point 280 to be repaired is moved to the laser incident position by driving the first slide 4 and the second slide 5 to move, and the rotating platform 3 is rotated to adjust the light emitting direction of the pixel point 280 to be repaired to be parallel to the plane where the swing direction is located. The display panel 200 is swung by the deflection component 2 to adjust the light emitting direction of the pixel point 280 to be repaired to coincide with the laser incident direction, and then the laser can be emitted to perform laser repair on the pixel point 280 to destroy the light emitting structure 240 of the pixel point 280 to be repaired. With this arrangement, the laser remains in a fixed position without adjustment, and the pixel points 280 to be repaired at different positions are moved to a fixed repair position through the display panel carrier 100, thereby improving the accuracy and yield of laser repair; and improving ease of use and simplifying the structure of the pixel bright spot repair system.

[0067] Please refer to Figure 3 In one embodiment, the carrying platform 1 can be raised and lowered along the normal direction of the carrying surface 11 .

[0068] In this embodiment, the lifting direction of the carrying platform 1 is the normal direction of the carrying surface 11. The height position of the pixel point 280 to be repaired can be adjusted by driving the carrying platform 1 to lift, so that the light-emitting structure 240 of the pixel point 280 to be repaired is located at the focal position of the laser focus, so that the laser accurately destroys the light-emitting structure 240 of the pixel point 280 to be repaired, thereby improving the repair yield. Optionally, a lifting mechanism can be set on the plane where the carrying platform 1 is installed to control the lifting of the carrying platform 1. The lifting mechanism can be set as a lifting cylinder, or a motor can be used as a driving part, and the carrying platform 1 can be driven to lift by a screw drive, a connecting rod mechanism, or a scissor-type lifting mechanism.

[0069] Optionally, the display panel carrier 100 is provided with a rotating component, a first slide 4 and a second slide 5 for adjusting the position of the display panel 200. At this time, the laser focus position can be located on the swing center axis of the swing path, and the light-emitting structure 240 of the pixel point located at the laser incident position is adjusted to the laser focus position by driving the supporting platform 1 to rise and fall. At this time, no matter to which angle the display panel 200 is swung, the height position of the light-emitting structure 240 of the pixel point located at the laser incident position remains unchanged. Therefore, when the pixel points at different positions are moved to the laser incident position by using the rotating component, the first slide 4 and the second slide 5, the laser can be accurately focused on the light-emitting structure 240 of the pixel point 280 to be repaired, thereby improving the laser repair accuracy and yield.

[0070] For details, please refer to Figures 4 to 10 When the display panel carrier 100 is applied to the pixel bright spot repair system, the swing direction of the supporting platform 1 driven by the deflection component 2 is defined as the first direction, and the direction perpendicular to the first direction and the laser incident direction is defined as the second direction. When the display panel carrier 100 is in the initial state, the supporting surface 11 of the supporting platform 1 and the display panel 200 are perpendicular to the laser incident direction, the central pixel point of the display panel 200 is aligned with the preset laser incident position, and a coordinate system is constructed with the laser incident position as the origin, with the first direction as the x-axis extension direction, and the second direction as the y-axis extension direction; based on this, the coordinates (X, Y) of the pixel point 280 to be repaired are obtained, and the light emission angle α of the pixel point 280 to be repaired relative to the normal direction of the display panel 200 can be obtained according to the coordinates of the pixel point 280 to be repaired, and α satisfies Wherein, R1 is the distance between the center pixel point and point S. When performing laser repair on the pixel point 280 to be repaired, the laser focus position is located at the same height as the swing center axis of the carrier platform 1, and the carrier platform 1 is driven to rise and fall so that the light-emitting layer 210 located at the display panel 200 is moved to the height position where the swing center axis of the carrier platform 1 is located. At this time, the light-emitting structure 240 of the pixel point located at the laser incident position will be located at the laser focus position, and the pixel point 280 to be repaired is moved to the laser incident position through the first slide 4 and the second slide 5, and the display panel 200 is driven to rotate through the rotating platform 3, so that the light emitting direction of the pixel point 280 to be repaired is located in the plane where the swing direction of the swing table 22 is located, and the rotation angle β when the pixel point 280 to be repaired is rotated to the plane where the light emitting path is located in the swing direction satisfies Then, the display panel 200 is driven to swing at an angle α by the deflection assembly 2, so that the light emitting direction of the pixel 280 to be repaired coincides with the laser incident direction. The laser emitted by the laser can accurately hit the light emitting structure 240 of the pixel 280 to be repaired, so as to destroy the light emitting structure 240 of the pixel 280 to be repaired and turn it into a dark pixel, thereby completing the laser repair.

[0071] The present invention also proposes a pixel bright spot repair system, which includes a laser and a display panel carrier 100. The specific structure of the display panel carrier 100 refers to the above embodiment, and the laser is used to emit laser to destroy the light emitting structure 240 of the pixel point 280 to be repaired. Optionally, the laser is arranged above the display panel carrier 100 to emit laser vertically downward to the display panel 200. Since the present pixel bright spot repair system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0072] The present invention also provides a pixel bright spot repair method, which is implemented by the pixel bright spot repair system in the above embodiment. The repair method comprises the following steps:

[0073] Step S10, swinging the display panel 200 to adjust the tilt angle of the display panel 200 so that the light emitting direction of the pixel point 280 to be repaired coincides with the laser incident direction;

[0074] Step S20 , emitting laser light toward the display panel 200 to destroy the light emitting structure 240 of the pixel 280 to be repaired.

[0075] In this embodiment, the display panel carrier 100 in the above-mentioned embodiment is used to install the display panel 200, so that the tilt angle of the carrying platform 1 can be adjusted by the deflection component 2, so that the tilt angle of the display panel 200 arranged on the carrying platform 1 can be adjusted. When it is necessary to repair the bright pixel in the display panel 200, the light emitting direction of the pixel point 280 to be repaired is adjusted to be the same as the incident direction of the laser, so that the laser can be accurately emitted on the light emitting layer 210 of the pixel point 280 to be repaired, so as to destroy the light emitting layer 210 of the pixel point 280 to be repaired and make the pixel point a dark spot; this repair method can avoid the problem of damage position offset due to the refraction of the microlens 260, and improve the success rate of laser repair.

[0076] In one embodiment, before the step S10 of swinging the display panel 200 to adjust the tilt angle of the display panel 200, the step further includes:

[0077] Step S1, aligning the central pixel point of the display panel 200 with the laser incident position;

[0078] Step S2, obtaining coordinate information of the pixel point 280 to be repaired relative to the central pixel point, and obtaining the swing angle of the display panel 200 according to the coordinate information;

[0079] Step S3, moving the display panel 200 to move the pixel point 280 to be repaired to the laser incident position;

[0080] Step S4, if the light emitting direction of the pixel 280 to be repaired and the swing direction are not in the same plane, rotate the display panel 200 to adjust the light emitting direction of the pixel 280 to be repaired to the plane where the swing direction is located.

[0081] In this embodiment, the swing direction of the support platform 1 driven by the deflection component 2 is defined as the first direction, and the direction perpendicular to the first direction and the laser incident direction is defined as the second direction. When the display panel carrier 100 is in the initial state, the support surface 11 of the support platform 1 and the display panel 200 are perpendicular to the laser incident direction, the central pixel point of the display panel 200 is aligned with the preset laser incident position, and a coordinate system is constructed with the laser incident position as the origin, with the first direction as the x-axis extension direction, and the second direction as the y-axis extension direction; the coordinates (X, Y) of the pixel point 280 to be repaired are detected and obtained, and the intersection of the light path of the central pixel point and the reverse extension line of the light path of the pixel point 280 to be repaired is defined as S. The light model of the display panel 200 can be regarded as a light emitting model with S as the cone center, and the light angle α of the pixel point 280 to be repaired relative to the normal direction of the display panel 200 can be obtained according to the coordinates of the pixel point 280 to be repaired, and α satisfies Among them, R1 is the distance between the center pixel and point S.

[0082] After obtaining the coordinates of the pixel point 280 to be repaired, the pixel point 280 to be repaired can be moved to the laser incident position by the first slide 4 and the second slide 5, and the display panel 200 is driven to rotate by the rotating platform 3, so that the light emitting direction of the pixel point 280 to be repaired is located in the plane where the swing direction of the display panel 200 is located, and the rotation angle β when the pixel point 280 to be repaired is rotated to the plane where the light emitting path is located in the swing direction satisfies Then, the display panel 200 is driven to swing at an angle α by the deflection assembly 2, so that the light emitting direction of the pixel 280 to be repaired coincides with the laser incident direction. The laser emitted by the laser can accurately hit the light emitting structure 240 of the pixel 280 to be repaired, so as to destroy the light emitting structure 240 of the pixel 280 to be repaired and turn it into a dark pixel, thereby completing the laser repair.

[0083] In this embodiment, when performing laser repair on the pixel point 280 to be repaired, the laser focus position is located at the same height as the swing center axis of the carrier platform 1, and the light-emitting structure 240 of the pixel point located at the laser incident position is also located at the height position where the swing center axis of the carrier platform 1 is located, so that when the pixel points at different positions are moved to the laser incident position, the laser can be accurately focused on the light-emitting structure 240 of the pixel point 280 to be repaired, thereby improving the laser repair accuracy and yield. Optionally, a carrier platform 1 of a specific size and thickness can be used, so that when the display panel 200 is installed on the carrier platform 1, the light-emitting structure 240 of the pixel point is located at the height position where the swing center axis of the carrier platform 1 is located; or the carrier platform 1 can be raised and lowered, and the light-emitting layer 210 of the display panel 200 is moved to the height position where the swing center axis of the carrier platform 1 is located by raising and lowering the carrier platform 1, so that the light-emitting structure 240 of the pixel point located at the laser incident position is located at the laser focus position.

[0084] In one embodiment, before the step S10 of swinging the display panel 200 to adjust the tilt angle of the display panel 200, the step further includes:

[0085] Step S5 , adjusting the height of the display panel 200 so that the light emitting layer 210 of the display panel 200 is located at the height position where the swing axis of the display panel 200 is located.

[0086] In this embodiment, the carrying platform 1 for placing the display panel 200 can be raised and lowered, and the light-emitting layer 210 of the display panel 200 is moved to the height position where the swing center axis of the carrying platform 1 is located by raising and lowering the carrying platform 1, so that the light-emitting structure 240 of the pixel point located at the laser incident position is located at the laser focus position; when the pixel points at different positions are moved to the laser incident position, the laser can be accurately focused on the light-emitting structure 240 of the pixel point 280 to be repaired, thereby improving the laser repair accuracy and yield. In addition, this setting method can improve the applicability of the display panel carrier 100, and can be used for laser repair of display panels 200 with different light-emitting layer 210 heights.

[0087] It should be noted that the step numbers in the embodiment of the present invention do not represent the order in which the steps are executed. For example, adjusting the height of the display panel 200 in step S5 can be performed before step S1, after step S4, or between steps S1 and S4, which is not limited here.
