The present application is described in detail below with reference to the figures and alternative embodiments.
The first embodiment is as follows:
fig. 1 is a schematic flowchart of a method for repairing a display panel according to a first embodiment of the present application, and as shown in fig. 1, the present application discloses a method for repairing a display panel, which includes the steps of:
s11: placing the display panel on a lighting table, and lighting the display panel;
s12: detecting the display panel, detecting whether a preset type of display problem exists, and if so, determining a position to be repaired;
s13: using the vibration surface of the vibration device to carry out vibration repair on the position to be repaired;
s14: and detecting the display state of the display panel, judging whether the repair is finished or not, and taking out the repaired display panel if the repair is finished.
The preset type of display problem that this application is directed to includes the present display problem that foreign matter gets into the liquid crystal layer and leads to. Compared with the display problem caused by the foreign matters, the display device has the advantages that the vibration device is adopted to vibrate the position where the foreign matters are located to be repaired in a vibration mode, so that the foreign matters are crushed and sparse and are dispersed, the density of the foreign matters is reduced, the influence on liquid crystal molecules of a liquid crystal layer is greatly reduced, the vibration can be transmitted, energy can be transmitted into the foreign matters from multiple angles, the foreign matters are more finely crushed, the spreading range is wider and more uniform, the influence on the liquid crystal molecules can be almost ignored, and the repair effect is obvious; even if the foreign matters fall into the space units, the foreign matters can still be broken by vibration to complete the repair, so that the success probability of the repair is improved; compared with a pressing mode, the novel multifunctional electric blanket can achieve the same fragmentation effect in a shorter time, save the repair time and improve the repair efficiency.
In step S14, it is observed whether the display panel has blush on the lighting table, and if the blush disappears, it is determined that the repair is completed, and the repaired display panel is taken out.
Due to the pair manufacturing process of the array substrate and the color film substrate of the display panel, the pair manufacturing process is often not performed in a vacuum environment but performed in an air environment, so that foreign matters in the air and foreign matters left after edging the substrates may enter a liquid crystal layer between the color film substrate and the array substrate, and the foreign matters may affect the normal deflection angle of liquid crystal molecules, for example. Under some conditions, the foreign matter can cause the liquid crystal molecules to deflect when not electrified, so that the light transmittance is increased due to the fact that the deflection angle of the liquid crystal molecules at the position where the foreign matter exists is too large after the display panel is electrified, the display problem of whitening and halo is caused, and the display effect of the display panel is influenced.
The traditional methods for avoiding foreign matter pollution mainly comprise two methods: firstly, the assembly of the display panel is completed in a vacuum environment, and then the liquid crystal is injected in an injection mode, so that the liquid crystal layer is ensured to be free of foreign matters, but the time and the cost spent by the manufacturing process are extremely high, and the development of enterprises is not facilitated; secondly, after the group assembly is completed, lighting inspection is carried out, abnormal positions are marked, then the display panel is transferred to a flat desktop, a pressing method is adopted for the abnormal positions to break the foreign matters, the influence on the deflection of liquid crystal molecules is reduced, but the repairing effect is poor, particularly when the foreign matters are located at the positions of the interval units, the abnormal display problem caused by the foreign matters is difficult to repair in an extruding mode, and the repairing time is long. The vibration repairing method adopting the vibration device can improve repairing efficiency and reduce repairing cost while ensuring repairing quality.
The preset type of display problem caused by the foreign matter falling into the liquid crystal layer includes, but is not limited to, a white band halo display problem caused by dust foreign matter or metal particles falling between the array substrate and the color film substrate in a machine table.
In step S13, the vibration surface of the vibration device is attached to the position to be repaired while the display panel is kept lit, and vibration repair is performed. Correspondingly, in step S14, the method includes:
s141: after the preset vibration frequency is used for vibration restoration and the preset time is reached, stopping the vibration device;
s142: detecting the display state of the display panel, judging whether the repair is finished or not, and taking out the repaired display panel if the repair is finished; otherwise, the vibration device is opened again to carry out vibration repair again on the position to be repaired until the repair is successful or the repair is judged to be impossible.
Specifically, the preset vibration time of the vibration device is 3-5 minutes, and preferably, the preset vibration time of the vibration device is 4 minutes; the preset vibration frequency of the vibration device is 20-50Hz, and preferably, the preset vibration frequency of the vibration device is 30 Hz. The vibration time can be preferably used for repairing most display panels, and the structure of the display panel cannot be damaged due to too long vibration time; and vibration frequency also obtains through experimental test repeatedly, and this vibration frequency can shake most foreign matters, and this vibration frequency can not lead to the fact obvious damage to display panel moreover, wherein can be through treating the continuous vibrations of restoration position earlier, reaches to predetermine after shaking the time, detects display panel's restoration effect again.
Further, in step S11, the display panel is placed on the lighting stand in a direction perpendicular to the horizontal plane, and the light exit surface of the display panel is aligned with the detection direction. The display panel is vertically placed, detection and restoration are carried out based on the angle of a viewer, so that the problem that whether a purchaser can observe abnormal display or not when the purchaser watches the display panel is conveniently known, and the detection and restoration effects are more targeted. Specifically, the color film substrate side of the display panel can be arranged far away from the lighting table, and only lighting is carried out from the array substrate side, and observation is carried out on the color film substrate side; the influence on the use of a user is larger when the foreign matter is closer to the color film substrate side, from the perspective of the user, the detection and the repair are performed on the color film substrate side of the display panel, when the foreign matter is closer to the color film substrate side, the phenomenon that the foreign matter causes the blushing of the display panel is more obvious, so that the abnormal display position can be quickly and accurately detected, the detection and the repair can be efficiently completed, when the foreign matter is closer to the array substrate side, the phenomenon that the blushing of the display panel is caused by the foreign matter is very small, the memory is basically omitted, and the repair is not performed to prevent the panel from being damaged.
In step S13, the vibration device is controlled to perform vibration repairing by controlling the vibration surface to move around, so that the foreign matter is uniformly broken, and the foreign matter is spread to a wider range by vibration of the circles, so that the broken foreign matter is smaller and smaller in the unit liquid crystal, the influence of the foreign matter on the deflection of the liquid crystal is further reduced, and the repairing effect is improved.
Moreover, the liquid crystal layer in the middle of the display panel is provided with the spacing units with uniform spacing, so if the foreign matters just appear near the spacing units, the method of pressing by fixed acting force can not contact the foreign matters or the contact is insufficient, so that the repair failure or the repair effect is not good, and the vibration repair mode can ensure that even if the foreign matters fall into the vicinity of the spacing units, the foreign matters can still be vibrated and crushed by vibration, so that the foreign matters are sparse and discrete, the vibration device is controlled to move around the center of the position to be repaired, and meanwhile, the vibration repair is carried out on the position to be repaired, so that the foreign matters can be ensured to always have a certain angle to achieve better vibration crushing effect, and can be dispersed more uniformly after the foreign matters are crushed, the crushed foreign matters are avoided, and the problem of the angle is still concentrated near the spacing units, leading to the problem of poor repair.
In order to enable the vibration device to achieve the effect of vibrating and smashing foreign matters and avoid the vibration device from damaging the display panel, a protection gasket can be arranged between the vibration device and the display panel to be repaired, and the display panel is prevented from being damaged.
In addition, the vibration device adopted by the application can be a high-frequency gun, of course, other suitable vibration devices except the high-frequency gun can also be adopted, and the gun head of the high-frequency gun is a circular head with the diameter of 2.5 cm; moreover, the gun head of the high-frequency gun is made of flexible materials, the gun head can be integrally made of the flexible materials, or the gun head can be made of the flexible materials only at the position of the gun tip, which is in contact with the display panel, and the gun head far away from the position of the gun tip can be made of hard materials and then assembled together; or the gun head is made of hard materials, and then a sleeve made of flexible materials is sleeved outside the gun head. The gun head and the protective pad made of the flexible material can be used simultaneously or only in the same way.
According to the observation, the foreign matters existing in the liquid crystal layer of the display panel are generally small in size and difficult to remove, the range of the phenomenon of the blushing zone halo caused by the small foreign matters is relatively small, the adopted spherical gun head with the diameter of 2.5cm can just cover the abnormal display area of the blushing zone halo, so that an operator can better control and repair the range to be moved, and the repair effect is better.
Example two:
fig. 2 is a schematic flowchart of a method for repairing a display panel according to a second embodiment of the present application, and as shown in fig. 2, a method for repairing a display panel is disclosed, which includes the steps of:
s21: placing the display panel on a lighting table, and lighting the display panel;
s22: detecting the display panel, detecting whether a preset type of display problem exists, and if so, determining a position to be repaired;
s23: keeping the display panel on, and simultaneously using the vibration surface of the vibration device to carry out vibration repair on the position to be repaired;
s24: and detecting the display state of the display panel, judging whether the repair is finished or not, and taking out the repaired display panel if the repair is finished.
The present embodiment is different from the first embodiment mainly in that step S23 is different from step S13. Compared with a pressing repairing mode, the abnormal position needs to be marked after the detection is finished, the display panel is placed on a flat plane for repairing, the time of about 7 minutes is probably needed for completing the whole detection and repairing step, the abnormal position does not need to be marked, the display panel does not need to be placed on a flat table top, the display panel can be repaired while lighting detection is carried out, the repairing condition can be observed in time, the repairing steps are fewer, the time needed by the detection and the repairing can be shortened to about 3 minutes, the repairing time is faster, the repairing is carried out while the detection is carried out, the repairing success rate is higher, and the possibility of damaging the substrate during the repairing is smaller.
Of course, in order to check the detection precision, the power supply of the display panel can be disconnected first and then the vibration repair is carried out, so as to ensure that the detection result is not affected by the vibration, and the detection precision is improved, specifically:
the step of detecting the display state of the display panel, judging whether the repair is successful, and if the repair is completed, taking out the repaired display panel comprises the following steps:
after the preset vibration frequency is used for vibration restoration and the preset time is reached, stopping the vibration device;
detecting the display state of the display panel, judging whether the repair is successful, and taking out the repaired display panel if the repair is completed; otherwise, the vibration device is opened again to carry out vibration repair again on the position to be repaired until the repair is successful or the repair is judged to be impossible. Namely, step S23 of the second embodiment is replaced with the two steps described above.
In addition, in order to optimize the environment for repairing the vibration, a repairing platform can be independently arranged to install the vibration device.
Example three:
fig. 3 is a schematic flowchart of a method for repairing a display panel according to a third embodiment of the present application, and as shown in fig. 3, a method for repairing a display panel is disclosed, which includes the steps of:
s31: placing the display panel on a lighting table, and lighting the display panel;
s32: detecting the display panel, detecting whether a preset type of display problem exists, and if so, determining a position to be repaired;
s33: disconnecting the power supply of the display panel, taking out the display panel and conveying the display panel to the repair platform through the conveying device;
s34: using the vibration surface of the vibration device to carry out vibration repair on the position to be repaired;
s35: after the repair is finished, the display panel is conveyed back to the lighting table through the conveying device, and the display panel is installed and lightened;
s36: and detecting the display state of the display panel, judging whether the repair is finished or not, and taking out the repaired display panel if the repair is finished.
Here, the steps S33 and S34 are modifications of the first embodiment, step S13, and the steps S35 and S36 are modifications of the first embodiment, step S14.
Compared with the method for detecting and repairing the lighting table, the lighting detection and the vibration repair are separated, and because the display problem caused by the fact that foreign matters fall into the liquid crystal layer does not exist in each display panel, the lighting table can continue to detect the subsequent panels when the vibration repair is carried out, and the time of the lighting table is not occupied; the lighting detection can be continuously carried out, the lighting detection and the repair time can be balanced, the power supply of the display panel is cut off, the display panel is taken out and is conveyed to the repair platform specially used for vibration repair through the conveying device, the targeted vibration repair is facilitated, and the repair effect is improved.
In addition, as the lighting table emits a more glaring white light, human eyes can be damaged in the process of watching the white light for a long time, and the lighting table consumes more energy, the lighting detection step and the vibration repair step are separated in the embodiment, so that the lighting table can be prevented from being started for a long time in the repair process, the energy consumption of the lighting table is reduced, the time of workers in a glaring white light environment is reduced, and the injury to the human eyes is reduced; after the repair is completed on the repair platform, the display panel is conveyed to the lighting table again for detection, and if the repair failure is detected, the display panel is repaired again, so that the repair reliability is improved.
The same as the first embodiment, the display panel of this embodiment also can be vertical when restoreing, and is concrete, can vertically place on restoreing the platform when restoreing, and the same reason is on lighting the lamp platform, also can be vertical and place, like this, lights a lamp and detects and shake when restoreing, and display panel all detects and restores based on viewer's angle, and it is more corresponding to detect and restore the effect. In addition, when the vibration is repaired, the vibration device moves around the center of the position to be repaired in a winding mode, and meanwhile vibration repair is carried out on the position to be repaired; wherein, the winding movement can be the self winding movement of the repair platform, and the vibration device is not moved; of course, the vibration device can move around, and the repair platform is not moved; the repairing platform and the vibrating device can move, but both can only move 180 degrees or slightly more than 180 degrees, and the repairing platform and the vibrating device are matched with each other, so that 360-degree winding movement can be realized.
Wherein, the transmission device can be a mechanical arm or a conveyor belt.
In addition, if the design of an independent repairing platform is adopted, the fact that an interactive module is added on the repairing platform can be considered, so that under the condition that the preset vibration frequency and the repairing time are applicable, the frequency and the repairing time which exceed the preset range can be adjusted through the interactive module. Of course, in the second embodiment, an interactive module may be added.

In the embodiment, the display panel 200 is placed on the lighting table 130, the display panel 200 is lighted, then the detection device 110 is used to detect the display panel 200, whether a preset type of display problem exists is detected, if so, the position to be repaired is determined, and the vibration device 120 is used to perform vibration repair on the position to be repaired of the display panel 200. Compared with the method of pressing to solve the display problem caused by the foreign matters, the vibration device 120 is adopted to sparsely disperse foreign matter molecules in a vibration mode, so that the density of the foreign matters is reduced and the foreign matters are crushed, the vibration is transmitted, energy can be transmitted into the foreign matters from multiple angles, the foreign matters are more finely crushed, the scattering range is wider, the foreign matters are more uniform, and the repair effect is obvious; compared with a pressing mode, the novel multifunctional electric blanket can achieve the same fragmentation effect in a shorter time, save the repair time and improve the repair efficiency.
