For example, two processes described in succession can be performed substantially at the same time, or in a sequence opposite to the described sequence.

[0049] Figure 1 is a schematic block diagram of a manufacturing device for a display device according to an embodiment of the present invention, Figure 2 It is a schematic plan view of a process section according to an embodiment of the present invention.

[0050] Reference Figure 1 and Figure 2 The manufacturing apparatus 1 of the display device may include a process unit 10 and a control unit 20 .

[0051] The process section 10 can perform a process on the article GD. The process section 10 can include a plurality of process lines 11, and each of the plurality of process lines 11 can include a plurality of process devices 111. The plurality of process devices 111 included in one process line 11 can perform the same process. Two or more of the plurality of process lines 11 can perform different processes. For example, each of the plurality of process lines 11 can perform different processes. At this time, the article GD can be processed while passing through the plurality of process lines 11 in sequence.

[0052] At least one of the plurality of process devices 111 may include a heat treatment device 12 (see Figure 4 ). For example, at least one of the plurality of process devices 111 may include a deposition device for depositing a deposition material onto the article GD. At least one of the plurality of process devices 111 may include a laser processing device 13 (see Figure 5 ). For example, at least one of the plurality of process devices 111 may include at least one of an exposure device for performing an extreme ultraviolet process (EUV) and a laser device for performing an ELA (Excimer Laser Annealing) process.

[0053] For example, the plurality of process lines 11 may include a first process line 11-1 including a plurality of first process devices 111-1, a second process line 11-2 including a plurality of second process devices 111-2, a third process line 11-3 including a plurality of third process devices 111-3, ... and an Nth process line 11-N including a plurality of Nth process devices 111-N.

[0054] In addition, for example, multiple first process devices 111-1 may include a 1-1 process device 111-11, a 1-2 process device 111-12, ... and a 1-N process device 111-1N, multiple second process devices 111-2 may include a 2-1 process device 111-21, a 2-2 process device 111-22, ... and a 2-N process device 111-2N, multiple third process devices 111-3 may include a 3-1 process device 111-31, a 3-2 process device 111-32, ... and a 3-N process device 111-3N, and multiple Nth process devices 111-N may include an N-1th process device 111-N1, an N-2th process device 111-N2, ... and a NNth process device 111-NN.

[0055] The first process line 11-1 can perform the first process, the second process line 11-2 can perform the second process, the third process line 11-3 can perform the third process, ..., and the Nth process line 11-N can perform the Nth process. That is, a plurality of first process devices 111-1 can perform the first process, a plurality of second process devices 111-2 can perform the second process, a plurality of third process devices 111-3 can perform the third process, ..., and a plurality of Nth process devices 111-N can perform the Nth process. The first process, the second process, the third process, ..., and the Nth process may be different processes from each other.

[0056] The article GD can be processed while moving on the first process line 11-1, the second process line 11-2, the third process line 11-3, ... and the Nth process line 11-N in sequence. For example, the article GD can be moved between the plurality of process lines 11 by a transport robot (not shown). The plurality of second process devices 111-2 can perform the second process on the article GD that has been subjected to the first process, the plurality of third process devices 111-3 can perform the third process on the article GD that has been subjected to the second process, ..., and the plurality of Nth process devices 111-N can perform the Nth process on the article GD that has been subjected to the N-1th process.

[0057] The first item GD1 supplied to the first supply line may be processed into the second item GD2 by performing the first process. The second item GD2 may be supplied to the second supply line along the moving path LT between the first supply line and the second supply line. The second item GD2 supplied to the second supply line may be processed into the third item GD3 by performing the second process. The third item GD3 may be supplied to the third supply line along the moving path LT between the second supply line and the third supply line. The third item GD3 supplied to the third supply line may be processed into the fourth item GD4 by performing the third process. The Nth item GDN supplied to the Nth supply line may be processed into the N+1th item GDN+1 by performing the Nth process. The N+1th item GDN+1 may be the final product manufactured by the manufacturing device 1 of the display device.

[0058] For example, the first item GD1 can be processed into the second item GD2 through the first process in the 1-1 process device 111-11, the second item GD2 can be processed into the third item GD3 through the second process in the 2-2 process device 111-22, the third item GD3 can be processed into the fourth item GD4 through the third process in the 3-1 process device 111-31, and finally, the Nth item GDN can be processed into the N+1th item GDN+1 through the Nth process in the NNth process device 111-NN.

[0059] exist Figure 2, a case where a plurality of process devices 111 are arranged in a row on one process line 11 is shown, but this is only an example, and the arrangement of the plurality of process devices 111 is not limited to this. In addition, a case where the article GD moves counterclockwise along a quadrilateral moving path LT between the plurality of process lines 11 is shown, but this is only an example, and the moving path LT of the article GD is not limited to this.

[0060] The control unit 20 can control the process unit 10. Figure 3 To be discussed later.

[0061] Figure 3 It is a schematic sequence diagram of a method for manufacturing a display device according to an embodiment of the present invention.

[0062] Reference Figures 1 to 3 The manufacturing apparatus 1 of the display device can consider the current process status and automatically save power while efficiently executing the process.

[0063] The plurality of process devices 111 may respectively implement the power saving mode. For example, the plurality of first process devices 111-1, the plurality of second process devices 111-2, the plurality of third process devices 111-3, ... and the plurality of Nth process devices 111-N may respectively implement the power saving mode.

[0064] That is, the plurality of process devices 111 can switch between the operating mode, the power saving mode, and the shut-down mode. In the operating mode, the plurality of process devices 111 can process the article GD. In the operating mode, the plurality of process devices 111 can continue to consume high power regardless of whether the article GD is currently being processed. In the power saving mode, the plurality of process devices 111 cannot process the article GD, and the amount of power used can be reduced compared to the operating mode. In the shut-down mode, the power supply of the plurality of process devices 111 can be turned off. Therefore, in the shut-down mode, the plurality of process devices 111 cannot process the article GD and do not consume power.

[0065] When the multiple process devices 111 are converted from the shutdown mode or the power saving mode to the working mode, a preparation time for preheating or setting may be required. In particular, when the multiple process devices 111 are converted from the shutdown mode to the working mode, it may take a considerable time. On the contrary, the time for the multiple process devices 111 to be converted from the power saving mode to the working mode can be shorter than the time for the multiple process devices 111 to be converted from the shutdown mode to the working mode.

[0066] The plurality of process devices 111 can adjust the power saving degree in a plurality of stages in the power saving mode. That is, the plurality of first process devices 111-1, the plurality of second process devices 111-2, the plurality of third process devices 111-3, ... and the plurality of Nth process devices 111-N can respectively adjust the power saving degree in a plurality of stages in the power saving mode. For example, the power saving degree can be adjusted between level 1 and level 10, and the higher the level, the higher the power saving degree can be.

[0067] In the high power saving mode, the power usage may be lower than that in the low power saving mode. However, the time to switch from the high power saving mode to the operating mode may be longer than the time to switch from the low power saving mode to the operating mode.

[0068] The control unit 20 can control the process unit 10 , and includes a management unit 21 , a scheduling machine 22 , and a TC (tool control) unit 23 .

[0069] The management unit 21 may generate an input variable IVL including information on the current process status and input the variable IVL to the scheduling machine 22 .

[0070] The input variable IVL may include the target number of articles GD to be processed in a specified time on each of the plurality of process lines 11, the number of the plurality of process devices 111 disposed in each of the plurality of process lines 11, and the processing speed of the process devices 111 disposed in each of the plurality of process lines 11. Here, the specified time may be one day (24 hours). That is, the input variable IVL may include the target number of articles GD to be processed in 24 hours on each of the plurality of process lines 11.

[0071] For example, the input variable IVL may include the target number of items GD to be processed within a specified time on the first process line 11-1, the second process line 11-2, the third process line 11-3,... and the Nth process line 11-N, the number of multiple first process devices 111-1, multiple second process devices 111-2, multiple third process devices 111-3,... and multiple Nth process devices 111-N, and the processing speeds of multiple first process devices 111-1, multiple second process devices 111-2, multiple third process devices 111-3,... and multiple Nth process devices 111-N.

[0072] Table 1 below is an example for explaining the aforementioned input variable IVL.

[0073] [Table 1]

[0074]

[0075]

[0076] The input variable IVL generated by the management unit 21 may include that the target number of items GD to be processed by the first process line 11-1 in one day is 400, the number of multiple first process devices 111-1 is 10, and the number of items GD that can be processed by multiple first process devices 111-1 in one day is 120.

[0077] The input variable IVL may include that the target number of items GD that the second process line 11-2 should process in one day is 550, the number of multiple second process devices 111-2 is 7, and the number of items GD that each of the multiple second process devices 111-2 can process in one day is 300.

[0078] In addition, the input variable IVL may include that the target number of items GD to be processed by the third process line 11-3 in one day is 600, the number of multiple third process devices 111-3 is 12, and the number of items GD that can be processed by multiple third process devices 111-3 in one day is 160.

[0079] In addition, the input variable IVL may include that the target number of items GD to be processed by the Nth process line 11-N in one day is 770, the number of multiple Nth process devices 111-N is 15, and the number of items GD that can be processed by multiple Nth process devices 111-N in one day is 170.

[0080] The scheduling machine 22 can receive information about the current process state from the management unit 21, and calculate the power saving content as a condition for effectively saving power in the process unit 10 without hindering the process of the process unit 10. That is, the scheduling machine 22 can receive the input variable IVL from the management unit 21, and output the output variable OVL including the power saving content to the management unit 21.

[0081] Here, the output variable OVL may include a power saving process device that is a target of the power saving mode, a power saving start time of the power saving process device, a power saving end time of the power saving process device, and a power saving degree of the power saving process device among the plurality of process devices 111. The power saving end time may be determined by taking into account the preparation time for switching from the power saving mode to the operating mode.

[0082] For example, the output variable OVL may include a power-saving process device that is the object of the power-saving mode among multiple first process devices 111-1, multiple second process devices 111-2, multiple third process devices 111-3,... and multiple Nth process devices 111-N, the power-saving start time of the power-saving process device, and the power-saving end time of the power-saving process device.

[0083] Table 2 below is an example for explaining the output variable OVL described above.

[0084] [Table 2]

[0085]

[0086]

[0087] The plurality of process devices 111 may maintain the operation mode except for the time described in Table 2.

[0088] The output variable OVL output by the scheduling machine 22 may include that the 1-1 process device 111-11 is maintained in a non-power saving state (operating mode) on the first process line 11-1, the 1-2 process device 111-12 is maintained in a power saving mode of level 3 from 12:00 to 12:30, maintained in a power saving mode of level 5 from 12:40 to 15:30 and maintained in a power saving mode of level 2 from 18:00 to 20:00, and the 1-N process device 111-1N is maintained in a power saving mode of level 3 from 07:00 to 12:30 and maintained in a power saving mode of level 5 from 15:00 to 21:00. That is, among the plurality of first process devices 111-1, the power saving process devices may be the 1-2 process device 111-12 and the 1-N process device 111-1N.

[0089] The output variable OVL may include that the 2-1 process device 111-21 on the second process line 11-2 is maintained in the power saving mode of level 6 from 09:20 to 10:50, maintained in the power saving mode of level 5 from 15:10 to 18:00, and maintained in the power saving mode of level 4 from 19:00 to 20:30, the 2-2 process device 111-22 is maintained in a non-power saving state (operating mode), and the 2-N process device 111-2N is maintained in the power saving mode of level 5 from 11:00 to 12:20, maintained in the power saving mode of level 7 from 13:40 to 16:30, and maintained in the power saving mode of level 3 from 17:20 to 17:30. That is, among the plurality of second process devices 111-2, the power saving process devices may be the 2-1 process device 111-21 and the 2-N process device 111-2N.

[0090] Furthermore, the output variable OVL may include that the 3-1 process device 111-31 on the third process line 11-3 is maintained in the power saving mode of level 2 from 07:20 to 12:50 and maintained in the power saving mode of level 4 from 15:10 to 21:10, the 3-2 process device 111-32 is maintained in the power saving mode of level 2 from 09:10 to 10:40, maintained in the power saving mode of level 3 from 15:50 to 18:10 and maintained in the power saving mode of level 2 from 19:10 to 21:40, and the 3-N process device 111-3N is maintained in the non-power saving state (operating mode). That is, among the plurality of third process devices 111-3, the power saving process devices may be the 3-1 process device 111-31 and the 3-2 process device 111-32.

[0091] Furthermore, the output variable OVL may include that the N-1th process device 111-N1 on the Nth process line 11-N is maintained in a non-power saving state (operating mode), the N-2th process device 111-N2 is maintained in a power saving mode of level 7 from 12:20 to 12:50, maintained in a power saving mode of level 5 from 13:30 to 15:20 and maintained in a power saving mode of level 5 from 18:10 to 20:10, and the NNth process device 111-NN is maintained in a power saving mode of level 6 from 07:30 to 13:00 and maintained in a power saving mode of level 5 from 15:30 to 21:20. That is, among the plurality of Nth process devices 111-N, the power saving process devices may be the N-2th process device 111-N2 and the NNth process device 111-NN.

[0092] The TC unit 23 can receive the output variable OVL from the management unit 21 and control the process unit 10 according to the output variable OVL. Therefore, the process unit 10 can operate according to whether or not, the power saving time, and the power saving degree of each of the plurality of process devices 111 included in the output variable OVL.

[0093] The management unit 21 may generate an inquiry signal for inquiring about the current power saving state of the process unit 10. The inquiry signal may be generated to check whether the current process is well executed without error even when at least one of the plurality of process devices 111 is in the power saving mode. Alternatively, the inquiry signal may be generated to correct the output variable OVL when the manufacturing plan of the manufacturing device 1 of the display device changes. For example, when the target number of articles GD to be processed in the first process line 11-1 in one day changes from 400 to 600, the inquiry signal may be generated.

[0094] The management unit 21 may generate the inquiry signal multiple times at certain time intervals. For example, the management unit 21 may generate the inquiry signal multiple times at intervals of 1 hour. Alternatively, the management unit 21 may generate the inquiry signal after 1 hour has passed from the power saving start time and 1 hour before the power saving end time.

[0095] The TC unit 23 may transmit the inquiry signal generated by the management unit 21 to the process unit 10. Therefore, the inquiry signal may be input from the management unit 21 to the process unit 10.

[0096] When the process section 10 receives the query signal, it can calculate a query variable indicating the current state of the process section 10. The query variable may include the number of articles GD processed so far on each of the plurality of process lines 11.

[0097] For example, the query variables may include the number of items GD processed so far on the first process line 11-1, the number of items GD processed so far on the second process line 11-2, the number of items GD processed so far on the third process line 11-3,... and the number of items GD processed so far on the Nth process line 11-N.

[0098] Next, the TC unit 23 can receive the query variable from the process unit 10 and transmit the query variable to the management unit 21. Therefore, the query variable can be input from the TC unit 23 to the management unit 21. The management unit 21 can compare the query variable, the input variable IVL, and the output variable OVL to determine whether the process unit 10 is operating with an error.

[0099] The management unit 21 can compare the ideal number of items GD that should be processed so far on multiple process lines 11 calculated based on the input variable IVL and the output variable OVL, and the actual number of items GD that have been processed so far on multiple process lines 11 included in the query variable. When the difference is greater than the specified value, it is judged that there is an error in the operation of the process unit 10. When the difference is less than the specified value, it is judged that the operation of the process unit 10 is normal.

[0100] If the management unit 21 determines that the operation of the process unit 10 is normal, the procedure can be terminated unless the management unit 21 generates an additional inquiry signal.

[0101] If the management unit 21 determines that there is an error in the work of the process unit 10, the management unit 21 can input the query variable and the input variable IVL to the scheduling machine 22. The scheduling machine 22 can receive the query variable and the input variable IVL, modify the output variable OVL, and output it to the management unit 21. The TC unit 23 can receive the modified output variable OVL from the management unit 21, and control the process unit 10 according to the modified output variable OVL.

[0102] The management unit 21 can compare with the situation where multiple process devices 111 are all in working state and calculate the amount of electricity saved. For example, the management unit 21 can calculate the amount of electricity saved by each of the multiple process lines 11. In addition, the management unit 21 can calculate the amount of electricity saved by each of the multiple process devices 111. The management unit 21 can calculate the amount of electricity saved during the day, week, month or year. The management unit 21 can communicate with the user device US. The management unit 21 can transmit the amount of electricity saved to the user device US. For example, the management unit 21 can transmit a chart to the user device US by showing the amount of electricity saved in a chart.

[0103] According to the embodiment of the present invention, unnecessary consumption of electric power caused by always setting the plurality of process devices 111 in the operating mode and rapid depreciation of various expensive components can be reduced.

[0104] Furthermore, according to the embodiment of the present invention, the inefficiency of the process caused by the considerable preparation time required when one or more of the plurality of process devices 111 is switched from the shutdown mode to the operating mode can be reduced.

[0105] That is, the embodiment of the present invention flexibly changes the power saving degree of each of the plurality of process devices 111 in consideration of the current process status, thereby improving the efficiency of the process and reducing unnecessary power consumption and depreciation of various components to reduce the manufacturing cost of the display device.

[0111] The temperature control unit 124 may be controlled by the TC unit 23. The TC unit 23 may adjust the degree of power saving by controlling the temperature control unit 124. That is, the TC unit 23 may control the temperature control unit 124 to reduce the heating value of the heating unit 122 when the degree of power saving of the process device 111 received from the management unit 21 is high, and may control the temperature control unit 124 to increase the heating value of the heating unit 122 when the degree of power saving of the process device 111 received from the management unit 21 is low.
