When the organic vaporizer 100 is operated, the first to fourth on-off valves 117a to 117d are opened to flow the first organic material and the second organic material stored in the organic material storage unit 111. [ At this time, the first actuator 118a and the second actuator 118b operate to allow the first organic material and the second organic material to flow from the organic material storage unit 111 to the organic material supply pipe 112.

Specifically, when the first actuator 118a and the second actuator 118b operate after the first opening / closing valve 117a and the third opening / closing valve 117c are opened, the first organic material and the second organic material 2 organic material may enter the first and second actuators 118a and 118b after passing through the first branch pipe 114a and the second branch pipe 114b from the first connection pipe 113 respectively.

When the above process is completed, the first actuator 118a and the second actuator 118b may be operated after the second on-off valve 117b and the fourth on-off valve 117d are opened. At this time, the first organic material and the second organic material may flow into the first branch pipe 114a and the second branch pipe 114b.

At this time, the first temperature control unit 122 and the second temperature control unit 132 may operate simultaneously or sequentially. Particularly, it is also possible that the first temperature control unit 122 operates first, and the second temperature control unit 132 operates when the controller 190 determines that a problem has occurred in the first barrel 121. [ Hereinafter, for convenience of explanation, the first temperature control unit 122 and the second temperature control unit 132 are sequentially operated.

Specifically, the control unit 190 may control the first temperature control unit 122 to operate to raise the internal temperature of the first barrel 121. At this time, the controller 190 may measure the temperature of the first temperature adjusting unit 122 to maintain the temperature of the first barrel 121 within a predetermined range.

Meanwhile, when the first temperature control unit 122 operates as described above, the first organic material in the first barrel 121 may be vaporized and formed into a gaseous state. At this time, in the first temperature measurement sensor part 181b installed in the first temperature control unit 122 and the first pressure measurement sensor part 181a installed in the first barrel 121, the temperature of the first vaporizer 120 And the pressure can be measured and transmitted to the control unit 190.

Specifically, the pressure inside the first barrel 121 measured by the first pressure measurement sensor unit 181a may be transmitted to the controller 190. At this time, the controller 190 may be in a state in which the first set pressure range is preset.

When the pressure of the first barrel 121 is equal to the first set pressure range, the controller 190 may control the first intermittent valve 161 to open to open the first flow pipe 141. That is, the controller 190 can control the first intermittent valve 161 to open when the pressure of the first barrel 121 reaches the first set pressure range. Also, the controller 190 can control the first intermittent valve 161 to open even when the pressure of the first barrel 121 is within the first set pressure range within the first set time. In this case, the first organic material of the first vaporizer 120 may move to the deposition chamber 170 and be deposited on the display panel. At this time, the controller 190 may control the second intermittent valve 162 to close.

Meanwhile, during the operation as described above, the first pressure measurement sensor unit 181a can continuously feed back the pressure of the first barrel 121 to the controller 190. [ At this time, the controller 190 may monitor the normal operation of the first vaporizer 120 based on the pressure of the first barrel 121.

When the pressure of the first barrel 121 and the first predetermined pressure range are different from each other based on the result of monitoring as described above, the control unit 190 may provide an external user with an alarm unit (not shown) to warn the user of the malfunction of the organic vaporizer 100 195). In particular, when the pressure of the first barrel 121 exceeds the first predetermined pressure range, the control unit 190 may operate the alarm unit 195 to warn an external user.

In addition to determining the malfunction of the organic vaporizer 100 by determining whether the pressure of the first barrel 121 is equal to the first set pressure range, 1 set pressure range, it is possible to determine the malfunction of the organic vaporizer 100.

Specifically, the controller 190 may continuously receive the pressure of the first barrel 121 from the first pressure measurement sensor unit 181a. At this time, the controller 190 may determine whether the pressure of the first barrel 121 is within the first set pressure range for a predetermined first set time. At this time, the controller 190 may determine that the organic vaporizer 100 malfunctions when the pressure of the first barrel 121 does not fall within the first set pressure range within the first set time. In particular, the controller 190 may determine that the first vaporizer 120 malfunctions.

There are two methods for determining whether or not the first carburetor 120 is malfunctioning, that is, determining whether the first set pressure is out of the first set pressure range, and determining whether the first vaporizer 120 enters the first set pressure range . Hereinafter, for the sake of convenience of explanation, the case where the malfunction of the first vaporizer 120 is detected and determined to be out of the first set pressure range will be described in detail.

When the pressure of the first barrel 121 exceeds the first set pressure range, the controller 190 controls the first valve 161 to operate and closes the first flow pipe 141 have.

On the other hand, the control unit 190 can control the second temperature control unit 132 to operate when the above operation is completed. At this time, the controller 190 may control the second temperature control unit 132 such that the second organic material of the second barrel 131 is at a predetermined pressure and temperature.

While the second organic material of the second barrel 131 is heated through the second temperature control unit 132 as described above, the second temperature measurement sensor unit 182b and the second pressure measurement sensor unit 182b The temperature of the temperature control unit 132 and the pressure of the second barrel 131 can be measured.

The measured temperature and pressure may be transmitted to the controller 190. In particular, the control unit 190 may control the second intermittent valve 162 based on the measured pressure.

Specifically, the pressure of the second barrel 131 measured through the second pressure measurement sensor unit 182a may be transmitted to the controller 190. The control unit 190 may compare the pressure of the second barrel 131 with a predetermined second set pressure range. At this time, the second set pressure range may be set equal to the first set pressure range.

The control unit 190 opens the second intermittent valve 162 to discharge the second organic material from the second barrel 131 to the deposition chamber 170 ). At this time, the method of determining whether the pressure of the second barrel 131 is equal to the second set pressure range is a method of determining whether the pressure of the second barrel 131 is within the second set pressure range, And determining whether the pressure of the barrel 131 is within the second set pressure range for a second set time period. Hereinafter, for the sake of convenience of explanation, a method of determining whether the pressure of the second barrel 131 is within the second set pressure range will be described in detail.

On the other hand, the second pressure measurement sensor unit 182a can continuously measure the pressure of the second barrel 131 in a state where the second intermittent valve 162 is opened. The measured pressure of the second barrel 131 can be continuously fed back to the control unit 190.

The control unit 190 may compare the pressure of the second barrel 131 to be fed back with the second set pressure range. At this time, if it is determined that the pressure of the second barrel 131 exceeds the second set pressure range, the controller 190 can warn an external user through the alarm unit 195. In addition, the control unit 190 may control the second intermittent valve 162 to close the second flow pipe 142.

In particular, the control unit 190 may stop the operation of the organic vaporizer 100 after controlling the second intermittent valve 162 to close as described above.

At this time, the control unit 190 may determine whether the pressure of the second barrel 131 is within the second set pressure range for the second set time, in addition to the above case. In particular, when the pressure of the second barrel 131 does not fall within the second set pressure range for a second predetermined time, the controller 190 determines that the second vaporizer 130 has failed, And the second intermittent valve 162 can be controlled.

Therefore, the organic vaporizer 100 can ensure continuity of operation when the second vaporizer 130 is operated by applying the organic layer to the display panel when a problem occurs in the operation of the first vaporizer 120.

In addition, the organic vaporizer 100 can prevent malfunction by determining the failure of the organic vaporizer 100 when depositing the organic material layer based on the pressures of the first vaporizer 120 and the second vaporizer 130, You can respond quickly.

FIG. 5 is a flow chart showing another embodiment of the control sequence of the organic vaporizing apparatus shown in FIG. 1. FIG. Hereinafter, the same reference numerals as above denote the same members as described above.

Referring to FIG. 5, the organic vaporizer 100 may be controlled based on at least one of the temperature of the first vaporizer 120 and the temperature of the second vaporizer 130. Specifically, the organic vaporizer 100 can be controlled based on the temperature of the first temperature regulating unit 122 and the temperature of the second temperature regulating unit 132. The method of controlling the organic vaporizer 100 based on at least one of the temperature of the first temperature adjusting unit 122 and the temperature of the second temperature adjusting unit 132 is the same as that of the first barrel 121 The pressure of the first barrel 131, the pressure of the second barrel 131, and the pressure of the second barrel 131.

Specifically, when the display panel is prepared, the display panel can be inserted into the deposition chamber 170. The organic vaporizer 100 may be operated after the display panel is inserted into the deposition chamber 170.

When the organic vaporizer 100 is operated, the first to fourth on-off valves 117a to 117d are opened to flow the first organic material and the second organic material stored in the organic material storage unit 111. [ At this time, the first actuator 118a and the second actuator 118b operate to allow the first organic material and the second organic material to flow from the organic material storage unit 111 to the organic material supply pipe 112.

Specifically, when the first actuator 118a and the second actuator 118b operate after the first opening / closing valve 117a and the third opening / closing valve 117c are opened, the first organic material and the second organic material 2 organic material may enter the first and second actuators 118a and 118b after passing through the first branch pipe 114a and the second branch pipe 114b from the first connection pipe 113 respectively. The first and second openings 117a and 117c can be closed after the first organic material and the second organic material respectively enter the first and second actuators 118a and 118b.

When the above process is completed, the first actuator 118a and the second actuator 118b may be operated after the second on-off valve 117b and the fourth on-off valve 117d are opened. At this time, the first organic material and the second organic material may flow into the first branch pipe 114a and the second branch pipe 114b.

The first organic material and the second organic material flowing as described above are gathered together from the first branch pipe 114a and the second branch pipe 114b to the first connection pipe 113 to be supplied to the first supply pipe 116a and the second supply pipe 116b, And the second supply pipe 116b, respectively. At this time, the first supply pipe 116a and the second supply pipe 116b may respectively supply the first organic material and the second organic material to the first vaporizer 120 and the second vaporizer 130, respectively.

When a predetermined amount of the first organic material and the second organic material are supplied to the first vaporizer 120 and the second vaporizer 130 as described above, the second on-off valve 117b and the fourth on-off valve 117d operate respectively The first branch pipe 114a and the second branch pipe 114b can be closed. Accordingly, the second on-off valve 117b and the fourth on-off valve 117d supply the first organic material and the second organic material to the first vaporizer 120 and the second vaporizer 130, respectively, Can be prevented from flowing backward from the first vaporizer (120) and the second vaporizer (130).

When the first organic material and the second organic material are supplied as described above, the first organic material and the second organic material may enter the first barrel 121 and the second barrel 131, respectively. At this time, the first organic material and the second organic material may be injected into the first and second barrels 121 and 131 through the ultrasonic nozzle.

When the first organic material and the second organic material are injected into the first and second barrels 121 and 131 as described above, the first temperature control unit 122 and the second temperature control unit 132, This can work. At this time, the first temperature control unit 122 and the second temperature control unit 132 may operate simultaneously or sequentially. Particularly, it is also possible that the first temperature control unit 122 operates first, and the second temperature control unit 132 operates when the controller 190 determines that a problem has occurred in the first barrel 121. [ Hereinafter, for convenience of explanation, the first temperature control unit 122 and the second temperature control unit 132 are sequentially operated.

Specifically, the control unit 190 may control the first temperature control unit 122 to operate to raise the internal temperature of the first barrel 121. At this time, the controller 190 may measure the temperature of the first temperature adjusting unit 122 to maintain the temperature of the first barrel 121 within a predetermined range.

Meanwhile, when the first temperature control unit 122 operates as described above, the first organic material in the first barrel 121 may be vaporized and formed into a gaseous state. At this time, the first temperature measurement sensor unit 181b installed in the first temperature control unit 122 may measure the temperature of the first vaporizer 120 and transmit the measured temperature to the controller 190.

Specifically, the temperature of the first temperature adjustment unit 122 measured by the first temperature measurement sensor unit 181b may be transmitted to the controller 190. [ At this time, the first preset temperature range may be preset in the controller 190.

If the temperature of the first temperature control unit 122 is equal to the first set temperature range, the control unit 190 may control the first intermittent valve 161 to open to open the first flow pipe 141. That is, the controller 190 may control the first intermittent valve 161 to open when the temperature of the first temperature adjusting unit 122 is within the first set temperature range. In addition, the controller 190 can control the first intermittent valve 161 to open even when the temperature of the first temperature adjusting unit 122 is within the first set temperature range within the third set time. In this case, the first organic material of the first vaporizer 120 may move to the deposition chamber 170 and be deposited on the display panel. At this time, the controller 190 may control the second intermittent valve 162 to close.

Meanwhile, during the operation as described above, the first temperature measurement sensor unit 181b can continuously feedback the temperature of the first temperature regulation unit 122 to the controller 190. [ At this time, the control unit 190 may monitor whether the first vaporizer 120 is operating normally based on the temperature of the first temperature adjustment unit 122.

When the temperature of the first temperature control unit 122 and the first set temperature range are different from each other based on the result of monitoring as described above, the control unit 190 may provide an external user with an alarm to warn the user of the malfunction of the organic vaporizer 100 The control unit 195 can be controlled. In particular, when the temperature of the first temperature adjusting unit 122 exceeds the first set temperature range, the controller 190 may operate the alarm unit 195 to warn an external user.

In addition to determining the malfunction of the organic vaporizer 100 by determining whether or not the temperature of the first temperature adjusting unit 122 is equal to the first set temperature range, It is possible to discriminate the malfunction of the organic vaporizer 100 by determining whether the first set temperature range is reached during the set time.

Specifically, the control unit 190 can continuously receive the temperature of the first temperature control unit 122 from the first pressure measurement sensor unit 181a. At this time, the controller 190 may determine whether the temperature of the first temperature adjusting unit 122 is within the first set temperature range for a predetermined third set time. At this time, if the temperature of the first temperature control unit 122 does not fall within the first set temperature range within the third set time, the controller 190 may determine that the organic vaporizer 100 malfunctions . In particular, the controller 190 may determine that the first vaporizer 120 malfunctions.

There are two methods for determining whether or not the first carburetor 120 is malfunctioning, that is, determining whether it is out of the first set pressure range, or determining whether the first vaporizer 120 enters the first set temperature range . Hereinafter, for the sake of convenience of explanation, a description will be made mainly on the case where it is determined whether or not the malfunction of the first vaporizer 120 is out of the first set temperature range.

When the temperature of the first temperature control unit 122 exceeds the first set temperature range, the control unit 190 controls the first valve 161 to operate and closes the first flow pipe 141 .

On the other hand, the control unit 190 can control the second temperature control unit 132 to operate when the above operation is completed. At this time, the controller 190 may control the second temperature control unit 132 such that the second organic material of the second barrel 131 is at a predetermined pressure and temperature.

The temperature of the second temperature adjusting unit 132 is measured through the second temperature measuring sensor unit 182b while heating the second organic matter of the second barrel 131 through the second temperature adjusting unit 132 as described above can do.

The measured temperature may be transmitted to the controller 190. In particular, the controller 190 may control the second intermittent valve 162 based on the measured temperature.

Specifically, the temperature of the second temperature adjustment unit 132 measured through the second pressure measurement sensor unit 182a may be transmitted to the control unit 190. [ The controller 190 may compare the temperature of the second temperature adjusting unit 132 with a predetermined second set temperature range. At this time, the second set temperature range may be set equal to the first set temperature range.

If it is determined that the second set temperature range and the temperature of the second temperature adjusting unit 132 are equal to each other, the controller 190 opens the second intermittent valve 162 to transfer the second organic material from the second barrel 131 to the deposition chamber (170). At this time, the method of determining whether the temperature of the second temperature adjustment unit 132 is equal to the second set pressure range is determined by determining whether the temperature of the second temperature adjustment unit 132 is within the second set temperature range ≪ / RTI > Further, in addition to the above method, it may include a method of determining whether or not the temperature of the second temperature adjusting unit 132 enters the second set temperature range during the fourth set time. Hereinafter, for the sake of convenience of explanation, a method of determining whether the temperature of the second temperature control unit 132 is within the second set temperature range will be described in detail.

On the other hand, the second pressure measuring sensor unit 182a can continuously measure the temperature of the second temperature adjusting unit 132 in a state in which the second intermittent valve 162 is opened. The measured temperature of the second temperature control unit 132 may be continuously fed back to the control unit 190. [

The control unit 190 may compare the temperature of the second temperature control unit 132 to be fed back with the second set temperature range. At this time, if it is determined that the temperature of the second temperature adjusting unit 132 has exceeded the second set temperature range, the controller 190 may warn an external user through the alarm unit 195. In addition, the control unit 190 may control the second intermittent valve 162 to close the second flow pipe 142.

In particular, the control unit 190 may stop the operation of the organic vaporizer 100 after controlling the second intermittent valve 162 to close as described above.

At this time, the control unit 190 may determine whether the temperature of the second temperature adjusting unit 132 is within the second set temperature range for the fourth set time other than the above case. In particular, when the temperature of the second temperature control unit 132 does not fall within the second set temperature range for the fourth predetermined time, the control unit 190 determines that the second vaporizer 130 has failed, 195 and the second intermittent valve 162 can be controlled.

Therefore, the organic vaporizer 100 can ensure continuity of operation when the second vaporizer 130 is operated by applying the organic layer to the display panel when a problem occurs in the operation of the first vaporizer 120.

In addition, the organic vaporizer 100 can prevent malfunction by determining the failure of the organic vaporizer 100 when depositing the organic material layer based on the pressures of the first vaporizer 120 and the second vaporizer 130, You can respond quickly.
