Embodiment Construction

[0052] The preferred embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used in these figures to denote the same or similar parts.

[0053] First, the printing ink according to the present invention will be explained in detail.

[0054] In one embodiment, the printing ink may include a viscosity modifier.

[0055] The viscosity modifier is an additive capable of adjusting the viscosity of the printing ink according to the magnitude of the stress applied to the printing ink. The viscosity modifier includes a thixotropic agent and a dilatant agent.

[0056] Thixotropy is a physical property in which when stress acts on a fluid, the viscosity of the fluid decreases, and as a result the fluid becomes a gel phase, and when the stress is removed from the fluid, the viscosity of the fluid increases , The structure is that the fluid becomes a sol phase. In ot...

Abstract

A printing ink and a phosphor slurry composition, a printer and a plasma display panel using the same, and a method of manufacturing the same are disclosed. The printing ink contains a viscosity modifying agent for changing viscosity of the printing ink when stress is applied to the printing ink. The phosphor composition includes phosphor powder, a dispersing agent, and a binder. The phosphor composition further includes a substance having thixotropy.

Description

[0001] This application claims the rights of Korean patent application Nos. 10-2005-0082616 filed on September 6, 2005 and Korean patent application 10-2005-0096222 filed on October 12, 2005, which are incorporated in their entirety. For reference. Technical field [0002] The present invention relates to a printing ink and fluorescent slurry composition, a printer and a plasma display panel using the same, and a manufacturing method thereof. Background technique [0003] A plasma display panel (hereinafter, referred to as "PDP") is a light-emitting device that uses a discharge phenomenon to display images. It is not necessary to install active components in each unit of the plasma display panel. As a result, the process of manufacturing the plasma display panel can be simplified, and the screen size of the plasma display panel can be easily increased. In addition, the response speed of the plasma display panel is high. Therefore, the plasma display panel is widely used as a displ...
