Based on this, this application has proposed an ageing treatment equipment.

The aging apparatus 100 comprises a pulse generator 11 and at least one switching device 12 connected to the pulse generator. The pulse generator 11 is used to connect the display panel through the switching device 12 to provide a driving signal to the display panel.

Further, referring to fig. 2 and fig. 3, fig. 3 is a schematic diagram of the connection between the pulse generator and the switching device in the aging processing apparatus according to the embodiment.
The pulse generator 11 includes a first output pin group 13 and a second output pin group 14, and the voltage timings of the first output pin group 13 and the second output pin group 14 are the same. The first set of output pins may include a first voltage path Vdate1, a second voltage path Vdate2, and a third voltage path Vdate 3; the second set of output pins 14 includes a fourth voltage path, Vdate4, a fifth voltage path, Vdate5, and a sixth voltage path, Vdate 6.

Specifically, the first voltage path Vdate1 may be at the same voltage timing as the fourth voltage path Vdate4, the second voltage path Vdate2 may be at the same voltage timing as the fifth voltage path Vdate5, and the third voltage path Vdate3 may be at the same voltage timing as the sixth voltage path Vdate 6. It should be noted that, the voltage timings of the two voltage channels are the same, and it can be understood that the two voltage channels share the high-low level time and the high-low level time, and the voltage channels used are doubled. Thus, the driving capability of the pulse generator 11 can be improved by providing voltage channels having the same voltage timing.
The connection between the pulse generator 11 and the adapter 12 needs to be adapted in response to the same voltage timing in each two voltage channels of the pulse generator 11. The transition device 12 includes at least a first connector 15 and a second connector 16, the first connector 15 may include a first signal pin 151, a second signal pin 152, and a third signal pin 153; the second connector 16 may include a fourth signal pin 161, a fifth signal pin 162, and a sixth signal pin 163.

Through the above connection manner, the voltage channels in the first output pin group 13 are only connected with the signal pins in the first connector 15; the voltage channels in the second output pin group 14 are only connected with the signal pins in the second connector 14, so that the first output pin group and the second output pin group equally load the display panel needing load.
The first connector 15 may further include a first station output pin group 154, and the first station output pin group 154 is used to connect the first display panel. The second connector 16 may further include a second station output pin set 164, and the second station output pin set 164 is used to connect a second display panel. According to the circuit connection, the pulse generator 11 drives the first display panel through the first output pin group 13, and the pulse generator 11 drives the second display panel through the second output pin group 14. It should be noted that, the station output pin group herein may include one output pin or a plurality of output pins, and the specific pin number may be designed according to different display panel models, and is not limited herein.
The pulse generator of the prior art burn-in apparatus includes six voltage channels, but only three of them are used in the burn-in process, and the other three are in an idle state. Also, the burn-in apparatus of the prior art is connected to each voltage channel per connector. In this embodiment, the other three idle voltage channels are respectively set to have the same voltage timing sequence as the voltage channels used, that is, the six voltage channels are divided into the first output pin group and the second output pin group having the same voltage timing sequence, and the circuit is modified, so that the idle voltage channels are utilized, and the driving capability of the aging processing device is improved.
The effect of improving the driving capability of the burn-in apparatus in the present embodiment is exemplified. If the pulse generator of the aging processing device in the prior art can simultaneously load 2 display panels, that is, each voltage channel needs to drive 2 display panels; in the aging processing device of the embodiment, the pulse generator simultaneously loads 2 display panels, but each voltage channel only needs to load 1 display panel, so that the driving capability of the aging processing device is improved. And, since the load of the display panel is equivalent to parallel connection, the reciprocal of the total resistance of the parallel circuit is equal to the sum of the reciprocal of the resistance of each branch circuit. Therefore, the display panel loaded in each voltage channel is reduced by half, which is equivalent to that the resistance in each voltage channel is doubled, so that the working current of the pulse generator can be reduced by half, and the condition that the pulse generator is burnt out due to overlarge working current is reduced.
At present, the aging current of some full high-definition display panels is 100-227 mA, the specification of a voltage channel in a pulse generator in the original aging processing equipment is 200mA, the working current in the voltage channel can be higher than the specification current of the voltage channel when the aging processing is carried out, and general hardware is not suitable for working under high power for a long time, so that the pulse generator can be damaged possibly under the condition. By using the aging processing device in this embodiment, the working current in each voltage channel can be reduced by half, and under the condition that the current specification of the voltage channel is not changed, the current capability equivalent to that of the pulse generator is changed to 400mA, and the driving capability is doubled. The aging current of some full high-definition display panels is about half of the aging current, and the pulse generator can not work under high power for a long time, so that the phenomenon of damage of the pulse generator caused by overlarge working current of the aging treatment of the display panels can be eliminated.
The present embodiment provides an aging apparatus that uses an idle voltage channel also for driving a display panel. In the case of driving the same display panel, the present embodiment drives two display panels by two output pin sets, that is, one display panel is driven by each voltage channel, whereas in the prior art, one output pin set drives two display panels, that is, two display panels are driven by each voltage channel. Therefore compare with the ageing treatment equipment of prior art, ageing treatment equipment in this embodiment reduces half to the ageing current when carrying out ageing treatment to display panel, has promoted the driving capability in other words, and the current capacity doubles, has eliminated the ageing current too big and has leaded to the phenomenon of equipment damage.
In order to fully utilize the driving capability of the pulse generator, one pulse generator can be connected with a plurality of switching devices, each switching device can be provided with at least two connectors, and one connector is used for connecting one display panel. Another embodiment of an aging treatment apparatus is provided. Referring to fig. 4, fig. 4 is a schematic structural diagram of another embodiment of an aging apparatus in the present application.
The aging apparatus 200 includes a pulse generator 21 and a relay 22. The pulse generator 21 comprises a first set of output pins 23 and a second set of output pins 24. The voltage timing sequences of the first output pin group 23 and the second output pin group 24 are the same, that is, the first output pin group 23 and the second output pin group 24 share the high-low level time and the high-low level time, and the number of the pin groups used is doubled. The adapter 22 comprises a first connector 25, a second connector 26, a third connector 27 and a fourth connector 28. The first output pin group 23 connects the first connector 25 and the third connector 27, and the second output pin group 24 connects the second connector 26 and the fourth connector 28.
Further, referring to fig. 4 and 5, fig. 5 is a schematic diagram of the connection between the pulse generator and the switching device in the aging processing apparatus according to the embodiment.
The first connector 25 includes a first signal pin 251, a second signal pin 252, and a third signal pin 253. The second connector 26 includes a fourth signal pin 261, a fifth signal pin 262, and a sixth signal pin 263. The third connector 27 includes a seventh signal pin 271, an eighth signal pin 272, and a ninth signal pin 273. The fourth connector 28 includes a tenth signal pin 281, an eleventh signal pin 282, and a twelfth signal pin 283.
The connection between the pulse generator 21 and the adapter 22 needs to be adapted in such a way that the voltage timings in each two voltage channels of the pulse generator 21 are the same. The first voltage channel Vdate1 may be connected with the first and seventh signal pins 251 and 271, the second voltage channel Vdate2 may be connected with the second and eighth signal pins 252 and 272, the third voltage channel Vdate3 may be connected with the third and ninth signal pins 253 and 273, the fourth voltage channel Vdate4 may be connected with the fourth and tenth signal pins 261 and 281, the fifth voltage channel Vdate5 may be connected with the fifth and eleventh signal pins 262 and 282, and the sixth voltage channel Vdate6 may be connected with the sixth and twelfth signal pins 263 and 283.
By the above connection manner, the voltage channels in the first output pin group 23 are only connected with the signal pins in the first connector 25 and the third connector 27; the voltage channels in the second output pin group 24 are connected only to the signal pins in the second connector 26 and the fourth connector 28, so that the first output pin group and the second output pin group equally load the display panel requiring load.
The first connector 25 includes a first station output pin group 254, and the first station output pin group 254 is used to connect the first display panel. The second connector 26 includes a second station output pin set 264, and the second station output pin set 264 is used for connecting a second display panel. The third connector 27 includes a third station output pin group 274, and the third station output pin group 274 is used for connecting a third display panel. The fourth connector 28 includes a fourth station output pin group 284, and the fourth station output pin group 284 is used for connecting a fourth display panel.
In the embodiment, the pulse generator 21 may also be connected to two switching devices 22, that is, the pulse generator 21 may drive 8 display panels simultaneously, but each voltage channel only needs to load 4 display panels, so that the driving capability of the aging processing device is greatly improved, the aging current generated during aging is reduced, and the phenomenon that hardware devices are burned due to too large aging current is eliminated.
In addition, white balance adjustment is also required for the display panel. The aging processing apparatus can perform white balance adjustment for one display panel at a time. In the aging processing device of the prior art, one register and one timer are independently used for one voltage channel. If the display panel is not connected to all the voltage channels of the aging apparatus according to the connection method in the above embodiment, it is impossible to identify which voltage channel is used by the display panel to be debugged in the aging apparatus, and thus the white balance adjustment of the display panel is impossible.
In this regard, the present application also proposes two methods of adjusting corresponding white balance. First, two voltage channels with the same voltage sequence share one register and one timer, and the aging processing device can directly adjust the voltage channels without identifying the voltage channels used. Specifically, the first voltage channel Vdate1 and the fourth voltage channel Vdate4 share a register and a timer, the second voltage channel Vdate2 and the fifth voltage channel Vdate5 share a register and a timer, and the third voltage channel Vdat3e and the sixth voltage channel Vdate6 share a register and a timer.
Secondly, the aging processing device is informed in advance which voltage channel is being used, and the aging processing device can adjust the voltage channel, that is, adjust the display panel according to a preset rule. For example, if the first voltage channel is used to adjust the first display panel and the second voltage channel is used to adjust the second display panel, when the aging processing device knows the rule and needs to adjust the second display panel, the aging processing device can directly adjust the second voltage channel.
In general, the display panel may be subjected to an aging process after white balance adjustment.
