Abstract
A method for fabricating a plasma display panel can improve contrast of a panel by using an inkjet printing method in forming a fluorescent layer in the fabrication process of the plasma display panel. Also, after charging a liquid flake of fluorescent ink with a charge of a predetermined polarity, contrast of the panel can be improved by inducing the injection direction of the liquid flake by charging an address electrode with a charge having an opposite polarity to the liquid flake so that the charged liquid flake can be printed in the center portion of the cell region.
Claims7
A method for fabricating a plasma display panel, comprising the steps of:
- sequentially forming a bottom plate film and an address electrode on an upper portion of a lower substrate;
- forming a dielectric film in the upper portion of the bottom plate film and address electrode;
- defining a cell region by forming a partition in the upper portion of the dielectric film;
- and
- forming a fluorescent layer using an inkjet printing method in the cell region.
A method for fabricating a plasma display panel in a method for forming fluorescent layer using an inkjet printing method, comprising the steps of:
- charging fluorescent ink injected from the nozzle with a positive electric charge by supplying a voltage from a first power supply unit to a charge electrode;
- and
- applying a negative voltage which is opposite to the charging state of the fluorescent ink from the second power supply unit to an address electrode.
