Abstract

An apparatus for manufacturing a light emitting display device includes a substrate transfer stage including a plurality of support plates arranged at an interval in a first direction, each of the plurality of support plates extending in a second direction; and at least one electric-field application module disposed on at least one side of the substrate transfer stage. The at least one electric-field application module includes a probe head including at least one probe pin; and a driver connected to the probe head to move the probe head at least up and down.

Claims (34)

1. An apparatus for manufacturing a light emitting display device, comprising:

a substrate transfer stage including a plurality of support plates arranged at an interval in a first direction, each of the plurality of support plates extending in a second direction; and

at least one electric-field application module disposed on at least a first side of the substrate transfer stage,

wherein the at least one electric-field application module comprises:

a probe head including at least one probe pin; and

a driver connected to the probe head to move the probe head at least up and down;

wherein the plurality of support plates comprise:

a first support plate disposed on a first edge of the substrate transfer stage;

a second support plate disposed on a second edge of the substrate transfer stage; and

at least one third support plate disposed between the first support plate and the second support plate;

wherein the at least one electric-field application module further comprises:

a first electric-field application module connected to the first support plate; and

a second electric-field application module connected to the second support plate.

2. The apparatus according to claim 1 , wherein the at least one electric-field application module comprises:

a first electric-field application module disposed on a first side of the substrate transfer stage; and

a second electric-field application module disposed on a second side of the substrate transfer stage to face the first electric-field application module.

3. The apparatus according to claim 2 , wherein the first and second electric-field application modules are driven independently of each other.

4. The apparatus according to claim 2 , wherein the first and second electric-field application modules are driven simultaneously.

5. The apparatus according to claim 1 , wherein the driver comprises at least one of:

a first driver that horizontally moves the probe head forwards and backwards or leftwards and rightwards; and

a second driver that vertically moves the probe head up and down.

6. The apparatus according to claim 1 , wherein the at least one electric-field application module comprises at least one sensor unit that senses a position of the probe head.

7. The apparatus according to claim 1 , wherein the at least one electric-field application module comprises:

a body connected to the probe head and the driver; and

at least one linear motion guide connected to the body.

8. The apparatus according to claim 1 , wherein the probe head comprises:

at least one first probe pin electrically connected to a first power line; and

at least one second probe pin electrically connected to a second power line.

9. The apparatus according to claim 8 , further comprising a power supply component electrically connected to the first and second probe pins through the first and second power lines.

10. The apparatus according to claim 1 , wherein the first electric-field application module is driven to apply a first voltage through the at least one probe pin.

11. The apparatus according to claim 10 , wherein the second electric-field application module is driven to apply a second voltage through the at least one probe pin.

12. The apparatus according to claim 5 , the first driver includes a first motor and a first ball screw connected to the first motor.

13. The apparatus according to claim 12 , the second driver includes a second motor and a second ball screw connected to the second motor.

14. The apparatus according to claim 13 , each of the first and second motors is a servomotor.
