Method and apparatus for manufacturing display apparatus

An apparatus for manufacturing a display apparatus, the apparatus comprising:

• a chamber;
• a first source unit configured to accommodate a first deposition material and comprising a first nozzle unit having a first nozzle, wherein the first nozzle is configured to supply the first deposition material into the chamber;
• and
• a second source unit configured to accommodate a second deposition material and comprising a second nozzle unit having a second nozzle, wherein the second nozzle is configured to supply the second deposition material into the chamber,
• wherein the first nozzle and the second nozzle are between a center of the first nozzle unit and a center of the second nozzle unit.

An apparatus for manufacturing a display apparatus, the apparatus comprising:

• a chamber;
• a source unit in the chamber, wherein the source unit is configured to supply a deposition material into the chamber;
• an angle restriction belt in the source unit or apart from the source unit, wherein the angle restriction belt is configured to rotate and restrict an injection angle of the deposition material injected from the source unit;
• a belt driver configured to rotate the angle restriction belt;
• a belt cooler configured to cool a surface of the angle restriction belt;
• and
• a belt heater configured to heat the surface of the angle restriction belt.

An apparatus for manufacturing a display apparatus, the apparatus comprising:

• a chamber;
• a source unit in the chamber, wherein the source unit is configured to supply a deposition material into the chamber;
• a sensor configured to measure a concentration of the deposition material injected from the source unit;
• a rotation driver connected to the sensor and configured to rotate the sensor;
• and
• a sensor heater configured removes the deposition material from the sensor by heating the sensor.

A method of manufacturing a display apparatus, the method comprising:

• arranging a display panel and a mask assembly in a chamber;
• supplying, into the chamber, a deposition material from at least one of a plurality of source units and depositing the deposition material on the display panel;
• measuring an inner temperature of at least one of the plurality of source units;
• comparing the measured inner temperature of the at least one of the plurality of source units with a pre-set temperature;
• interrupting the deposition material supplied from the at least one of the plurality of source units into the chamber;
• and
• supplying the deposition material from at least another of the plurality of source units into the chamber.

A method of manufacturing a display apparatus, the method comprising:

• arranging a display panel and a mask assembly in a chamber;
• supplying, into the chamber, a first deposition material from a first source unit;
• supplying, into the chamber, a second deposition material from a second source unit;
• and
• depositing the first deposition material and the second deposition material on the display panel,
• wherein the first source unit comprises a first nozzle unit having a first nozzle configured to guide the first deposition material, the second source unit comprises a second nozzle unit having a second nozzle configured to guide the second deposition material, and the first nozzle and the second nozzle are between a center of the first nozzle unit and a center of the second nozzle unit.

A method of manufacturing a display apparatus, the method comprising:

• arranging a display panel and a mask assembly in a chamber;
• supplying, into the chamber, a deposition material from a source unit and depositing the deposition material on the display panel;
• measuring, via a first sensor, an evaporation rate of the deposition material injected from the source unit;
• and
• replacing the first sensor with a second sensor which is different from the first sensor, after a certain time period.

An apparatus for manufacturing a display apparatus, the apparatus comprising:

• a chamber;
• a plurality of source units outside the chamber, wherein the plurality of source units are configured to accommodate a deposition material and to transform the deposition material into gas;
• a nozzle unit in the chamber and connected to the plurality of source units, wherein the nozzle unit is configured to inject, into the chamber, the deposition material supplied from one of the plurality of source units;
• and
• a regulation unit between each of the plurality of source units and the nozzle unit, wherein the regulation unit is configured to control the deposition material supplied from each of the plurality of source units to the nozzle unit and to selectively connect the plurality of source units with the nozzle unit,
• wherein the regulation unit is configured to disconnect, from the nozzle unit, a source unit from among the plurality of source units, of which the deposition material is exhausted, and to connect, to the nozzle unit, a source unit from among the plurality of source units, of which the deposition material is not exhausted.
