Abstract
Abstract A barrier rib forming method for a PDP including a process of forming an emulsion layer as a filmed deposition upon a glass substrate having transparent electrodes thereon. Exposing the film to ultraviolet rays to produce electrodes with a proper pattern of an emulsion layer thereon. Printing, drying and heating a glass paste deposited on said emulsion. Ultrasonically vibrating the glass substrate to remove the emulsion layer and glass paste from the glass substrate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
108 words
A barrier rib forming method for fabricating a plasma display panel comprising the steps of: forming an emulsion layer by deposition of an emulsion on a glass substrate upon which transparent electrodes are formed; exposing and developing said emulsion layer with ultraviolet rays to selectively form emulsion layers only on the electrodes; printing a barrier rib material including glass particles over said glass substrate and over said electrodes upon which said emulsion layer remains; heating said glass substrate printed with said barrier rib material; and, ultrasonically vibrating said glass substrate to selectively remove said emulsion layer and barrier rib material thereby leaving barrier ribs between said transparent electrodes.
Claim 2
Dependent Claim
108 words
A barrier rib forming method for fabricating a plasma display panel comprising the steps of: forming an emulsion layer by deposition of an emulsion on a glass substrate upon which transparent electrodes are formed; exposing and developing said emulsion layer with ultraviolet rays to selectively form emulsion layers only on the electrodes; printing a barrier rib material including glass particles over said glass substrate and over said electrodes upon which said emulsion layer remains; heating said glass substrate printed with said barrier rib material; and, ultrasonically vibrating said glass substrate to selectively remove said emulsion layer and barrier rib material thereby leaving barrier ribs between said transparent electrodes.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said emulsion layer is exposed to said ultraviolet rays with wavelengths of 310 nm-460 nm for a period of 60-120 seconds.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein said glass substrate printed with barrier rib material is heated to a temperature of 120° C.-600° C. for about an hour.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein said ultrasonically vibrating step employs ultrasonic vibrations exceeding 50 KHz.
