A laser-induced thermal spray printing process for phosphor layer deposition of PDP

An efficient printing process, called laser-induced thermal spray printing (LITSP), is introduced in this work to deposit the phosphor layer of the plasma display panel. LITSP is a non-contact printing process, which transfers the phosphor paste from the donor plate to the substrate by the bubble pressure induced by laser heating. The mechanism of the LITSP is analysed through numerical calculation and experiments. The temperature distribution of the donor plate is calculated to explain the paste ejection phenomena, and the proper paste composition and laser heating condition are determined experimentally. The entire phosphor paste is ejected successfully from the etched hole of the donor plate when the etched hole bottom is heated.
