Abstract

A curing device comprises a reaction chamber, a workbench provided at a bottom of the reaction chamber, an ultraviolet lamp provided at the top of the reaction chamber for irradiating the workbench, and a light shielding plate provided under the ultraviolet lamp for shielding the second area of the workbench from the light of the ultraviolet lamp. The workbench comprises a first area and a second area surrounded by the first area, the first area corresponds to a non-display area of a display panel to be produced, and the second area corresponds to the display area of the display panel to be produced. The workbench comprises a heating device.

Claims (27)

1. A curing device comprising:

a reaction chamber;

a workbench provided at a bottom of the reaction chamber, wherein the workbench comprises a first area and a second area surrounded by the first area, the first area corresponds to a non-display area of a display panel to be produced, and the second area corresponds to the display area of the display panel to be produced;

an ultraviolet lamp provided at the top of the reaction chamber for irradiating the workbench; and

a light shielding plate provided under the ultraviolet lamp for shielding the second area of the workbench from the light of the ultraviolet lamp,

wherein the workbench comprises a heating device.

2. The curing device as defined in claim 1 , wherein the heating device comprises a conductive heating tube provided in the workbench, and the curing device further comprises a wire for connecting the conductive heating tube with a power supply.

3. The curing device as defined in claim 1 , wherein the heating device comprises a vent line in the workbench, an air blowing hole for blowing hot air into the vent line, and an air outlet hole for exhausting the hot air in the vent line.

4. The curing device as defined in claim 1 , wherein the workbench is a transparent workbench, and the heating device is an infrared lamp for irradiating the panel.

5. The curing device as defined in claim 1 , wherein the light shielding plate is provided with an auxiliary heating device.

6. The curing device as defined in claim 5 , wherein the auxiliary heating device is an infrared lamp provided under the light shielding plate for irritating the workbench.

7. The curing device as defined in claim 2 , wherein the light shielding plate is provided with an auxiliary heating device.

8. The curing device as defined in claim 7 , wherein the auxiliary heating device is an infrared lamp provided under the light shielding plate for irritating the workbench.

9. The curing device as defined in claim 3 , wherein the light shielding plate is provided with an auxiliary heating device.

10. The curing device as defined in claim 9 , wherein the auxiliary heating device is an infrared lamp provided under the light shielding plate for irritating the workbench.

11. The curing device as defined in claim 4 , wherein the light shielding plate is provided with an auxiliary heating device.

12. The curing device as defined in claim 11 , wherein the auxiliary heating device is an infrared lamp provided under the light shielding plate for irritating the workbench.

13. The curing device as defined in claim 1 , wherein an auxiliary heating device is provided on a sidewall of the reaction chamber.

14. The curing device as defined in claim 2 , wherein an auxiliary heating device is provided on a sidewall of the reaction chamber.

15. The curing device as defined in claim 3 , wherein an auxiliary heating device is provided on a sidewall of the reaction chamber.

16. The curing device as defined in claim 4 , wherein an auxiliary heating device is provided on a sidewall of the reaction chamber.

17. A method of manufacturing a liquid crystal display panel using the curing device as defined in claim 1 , the method comprising steps of:

dropping liquid crystal materials on a plurality of panel areas of a color filter substrate;

coating an adhesive material in a plurality of panel areas of an array substrate;

assembling the color filter substrata and the array substrate together in a vacuum curing chamber to form an assembled panel;

curing the adhesive material and heating the liquid crystal materials by the curing device; and

cutting the assembled panel to form a plurality of liquid crystal display panels.
