Abstract

A manufacturing method of display with lighting devices is disclosed, including providing a tank containing a liquid; disposing a carrying plate with several recessed regions in the tank, and the carrying plate being immersed in the liquid; dropping several lighting devices into the liquid, wherein each of the lighting devices includes two conductive pads, and one of the two conductive pads includes a magnetic material; applying a magnetic field for the lighting devices and the lighting devices will dispose within the recessed regions of the carrying plate; removing the carrying plate with the lighting devices out of the tank, and assembling the lighting devices to an array substrate.

Claims (21)

1. A manufacturing method of display with lighting devices, comprising:

providing a tank containing a liquid;

disposing a carrying plate with a plurality of recessed regions in the tank, and the carrying plate being immersed in the liquid;

dropping a plurality of lighting devices into the liquid, wherein each of the lighting devices includes at least two conductive pads, and at least one of the at least two conductive pads includes a magnetic material;

applying a magnetic field for the lighting devices and disposing the lighting device within the plurality of recessed regions of the carrying plate; and

removing the carrying plate with the lighting devices out of the tank, and assembling the lighting devices to an array substrate.

2. The manufacturing method according to claim 1 , wherein the carrying plate is disposed at a bottom surface of the tank, wherein a magnetic field direction of the magnetic field is in parallel with an upper surface of the carrying plate.

3. The manufacturing method according to claim 2 , wherein only one of the at least two conductive pads of the each of lighting devices includes the magnetic material, and the magnetic field direction of the magnetic field is in parallel with an aligning direction of the at least two conductive pads.

4. The manufacturing method according to claim 2 , wherein the at least two conductive pads of the each of the lighting devices include the magnetic material, and the magnetic field direction of the magnetic field is vertical to an aligning direction of the at least two conductive pads.

5. The manufacturing method according to claim 1 , wherein the carrying plate is disposed at a bottom surface of the tank, and a tilted angle θ between an upper surface of the carrying plate and the horizontal level is in a range of 0 to 90 degrees.

6. The manufacturing method according to claim 5 , wherein the magnetic field has a magnetic field direction parallel to an upper surface of the carrying plate.

7. The manufacturing method according to claim 5 , wherein the magnetic field has a magnetic field direction parallel to the horizontal level.

8. The manufacturing method according to claim 7 , wherein the magnetic field has another magnetic field direction vertical to an upper surface of the carrying plate.

9. The manufacturing method according to claim 1 , wherein the carrying plate is disposed at a sidewall of the tank and vertical to a horizontal level, and the magnetic field has a magnetic field direction perpendicular to an upper surface of the carrying plate.

10. The manufacturing method according to claim 9 , wherein only one of the at least two conductive pads of the each of the lighting devices includes the magnetic material, and the magnetic field further has another magnetic field direction in parallel with an aligning direction of the at least two conductive pads of the each of the lighting devices.

11. The manufacturing method according to claim 9 , wherein the at least two conductive pads of the each of the lighting devices include the magnetic material, and the magnetic field further has an another magnetic field direction in parallel with the carrying plate but perpendicular to an aligning direction of the at least two conductive pads of the each of the lighting devices.

12. The manufacturing method according to claim 1 , wherein the magnetic field has a first magnetic field direction and a second magnetic field direction, wherein the first magnetic field direction and the second magnetic field direction are applied at different time periods.

13. A display with lighting devices, comprising:

an array substrate, comprising a plurality of sub-pixel regions; and

a plurality of lighting devices disposed on the array substrate,

wherein at least one of the plurality of lighting devices is disposed correspondingly to each of the plurality of sub-pixel regions, and the at least one of the plurality of lighting devices includes two conductive pads, and one of the two conductive pads includes magnetic material.
