Detailed Description
The following describes in detail a specific embodiment of a device for repairing a display panel defect and a method for repairing a display panel defect according to an embodiment of the present invention with reference to the drawings.
An apparatus for repairing a display panel defect provided in an embodiment of the present invention, as shown in fig. 2, includes: a fixed-position laser transmitter 001, a first reflecting plane mirror 002 disposed on an optical path of laser light emitted from the laser transmitter 001, and a control section 003 connected to the first reflecting plane mirror 002; wherein,
the control component 003 is used for driving the first reflecting plane mirror 002 to rotate around the rotating shaft a within a set angle range alpha;
the first reflecting plane mirror 002 is used for reflecting the laser emitted by the laser emitter 001 to the defective pixel area 004 to be repaired of the display panel.
Specifically, in the device for repairing a defect of a display panel according to the embodiment of the present invention, because the laser emitter 001 with a relatively large weight is in a stationary state, the first reflective plane mirror 002 is controlled to rotate to repair the defective pixel area 004 to be repaired by laser, so that the laser moving speed can be increased to a very high degree, thereby achieving the purpose of increasing the laser repair speed and the repair effect.
In specific implementation, in the apparatus for repairing a defect in a display panel according to an embodiment of the present invention, there are various specific structures for enabling the control component 003 to drive the first reflective plane mirror 002 to rotate around the rotation axis a within the predetermined angle range α. Specifically, as shown in fig. 2, the control section 003 may include: a rotary disc 0031 capable of rotating around the center B, a chute 0032 arranged on the surface of the rotary disc 0031, and a link mechanism 0033; wherein, one end of the chute 0032 is connected with the center B of the rotating disc 0031, and the other end can be arranged at any position on the surface of the rotating disc 0031; the first end of the link mechanism 0033 is fixedly connected to the first reflective plane mirror 002, and as shown in fig. 3, the second end is hinged to the chute 0032 through a rotatable shaft sleeve 0034, that is, the second end of the link mechanism 0033 is fixedly sleeved in the rotatable shaft sleeve 0034, and the rotatable shaft sleeve 0034 is hinged to the chute 0032. When a defective pixel area 004 to be repaired is maintained, the rotary disc 0031 rotates around the center B, the sliding groove 0032 arranged on the surface of the rotary disc 0031 is driven to do circular motion with the center B, and the sliding groove 0032 drives the connecting rod mechanism 0033 connected through the rotatable shaft sleeve 0034 to move in the process of motion, so that the first reflecting plane mirror 002 connected with the first end of the connecting rod mechanism 0033 does reciprocating motion around the rotating shaft A in a certain angle range, and the first reflecting plane mirror 002 has different incidence angles and reflection angles relative to irradiated laser, thereby strictly controlling the irradiation distance of the laser to be S, and performing laser maintenance on the defective pixel area 004.
In practical implementation, in the apparatus for repairing a defective display panel provided in the embodiment of the present invention, the rotating disc 0031 may specifically adopt a rotating disc 0031 connected to a servo motor, that is, the rotating disc 0031 rotates around the center B under the driving of a motor of the servo motor, and the rotating speed of the rotating disc, that is, the rotating speed n, may be controlled by the servo motor to control the moving speed of the defective display area irradiated by the laser. Specifically, the larger the rotation speed n of the turntable 0031, the faster the first reflecting plane mirror 002 rotates around the rotation axis a, and the faster the laser beam is irradiated to the defective pixel region 004, so that the laser beam maintenance speed and maintenance effect are better.
In practical implementation, the repair device for defective display panels provided by the embodiment of the present invention may repair display panels with different pixel sizes, that is, the round trip irradiation distance S of the laser on the display panel needs to be adjusted according to the size of the defective pixel area 004. As shown in fig. 4, the angular ranges α 1, α 2, α 3 of the first reflecting plane mirror 002 rotating around the rotation axis a gradually increase, and correspondingly, the round trip irradiation distances S1, S2, S3 of the laser light on the display panel also gradually increase. Therefore, the size of the laser movement range can be controlled by controlling the angle range of the prism rotation. In view of this, in the control component 003 of the apparatus for repairing a defective display panel according to the embodiment of the present invention, as shown in fig. 3, the rotatable sleeve 0034 may be hinged to the chute 0032 by the micro-moving motor 0035, and before performing laser maintenance, the micro-moving motor 0035 controls the rotatable sleeve 0034 to move on the chute 0032, and the farther the distance L between the rotatable sleeve 0034 and the center B of the rotating disc 0031 is, the larger the angular range α of the first reflecting plane mirror 002 rotating around the rotating shaft a is, the larger the back-and-forth irradiation distance S of laser light on the display panel is.
In a specific implementation, the apparatus for repairing a display panel defect according to an embodiment of the present invention, as shown in fig. 5, may further include: a fixed-position reflecting member 005 disposed on the optical path between the laser emitter 001 and the first reflecting plane mirror 002; the reflecting member 005 is used to reflect the laser beam emitted from the laser emitter 001 to the first reflecting plane mirror 002. That is, the fixed position of the laser emitter 001 may be set as needed, and the optical path of the laser beam may be changed by using the reflecting member 005 so that the laser beam may be incident on the first reflecting plane mirror 002 at a desired fixed angle.
Specifically, in the repair apparatus for a display panel defect according to the embodiment of the present invention, the reflective member 005 may be a second reflective mirror or a reflective prism, which is not limited herein.
Based on the same inventive concept, the embodiment of the present invention further provides a method for repairing the display panel defect by using the repairing apparatus provided by the embodiment of the present invention, which specifically includes the following steps:
the control component 003 drives the first reflecting plane mirror 002 to rotate around the rotating shaft a within a set angle range α, so that the first reflecting plane mirror 002 reflects the laser emitted by the laser emitter 001 to the defective pixel region 004 to be repaired of the display panel, and the defective pixel region 004 is repaired.
Specifically, in the repair method provided by the embodiment of the present invention, the laser emitter with a relatively large weight is set to be in a stationary state, and the laser is maintained in the defective pixel area 004 to be repaired by controlling the rotation of the first reflective plane mirror 002, so that the laser moving speed can be increased to a very high degree, and the purposes of increasing the laser maintenance speed and improving the maintenance effect are achieved.
Further, in the repair method provided by the embodiment of the present invention, in order to be suitable for display panels with different pixel sizes, the method may further include the following steps:
determining the angle range alpha of the first reflecting plane mirror 002 required to rotate according to the area of the defective pixel area 004;
and adjusting the distance S between the rotatable shaft sleeve 0034 and the center B of the rotary disc 0031 by adopting a micro moving motor 0035 according to the determined angle range alpha of the first reflecting plane mirror 002 required to rotate.
