Description
Technical field
The present invention relates to plasma panel preparation field, in particular to a kind of plasma display screen barrier and preparation method thereof and plasma panel.
Background technology
Color plasma display (Plasma Display Panel, be called for short PDP), to utilize gas discharge to produce vacuum-ultraviolet light (VUV), this ultraviolet light excites again three primary colors fluorescent material and produces red-green-blue light, then pass through room and time realization of debugging image demonstration.AC surface discharging type plasma display screen, is divided into front-back baseboard.Prebasal plate comprises transparency electrode ITO, and on transparency electrode ITO layer sustain discharge electrode X electrode and the scanning sparking electrode Y electrode of alternative arrangement, on X, Y electrode, be coated with certain thickness dielectric layer, then on dielectric layer, deposit one deck MgO film; Metacoxal plate is included in the barrier on the addressing electrode on glass substrate, the dielectric layer that covers this electrode and dielectric layer with certain altitude, barrier discharge space is kept apart and therein coating blue, green, red trichromatism fluorescent material.Subsequently forward and backward glass substrate is sealed together and is filled with gas.Through faint discharge generation wall electric charge between Y electrode and ADD addressing electrode, when energising, between X, Y electrode, can produce electric discharge, the ultraviolet light of generation can excite the three primary colors fluorescent material in barrier groove to send visible ray.
PDP display screen is by forward and backward substrate and be produced on the function elements such as electrode on substrate, barrier, medium, fluorescent material and form.It is the bottleneck in PDP processing procedure that barrier is made always, and particularly, along with the raising of PDP resolution, it is more and more higher that PDP barrier is made required precision.The preparation method of traditional plasma display screen barrier utilizes sand-blast, and dielectric paste is painted on glass substrate, forms dielectric layer, forms barrier layer thereby then print barrier size, and coating is evenly also dry.Last barrier layer is covered by DFR (dry film resist), and DFR can resist sandblast etching.Utilizing template, DFR, barrier material layer by the exposure of selectivity, the DFR after exposure has chemical stability, after developing, forms barrier mask, and ability sand grains se.Then by air-flow, sand grains is sprayed onto on barrier layer, has the barrier material layer of DFR to be retained, form barrier, remaining barrier material layer is all fallen by spray.After sandblast, barrier mask is taken off (stripping), and carries out sintering, thereby forms barrier.
At present, barrier sandblast is generally thicker with DFR film, and dry film is at 40～60 μ m, and when development, swelling DFR film thickness will reach 50～80 μ m, like this DFR film after development in retrofit process, sidewall precipitous very important, development conditions is very harsh.The prepared barrier machining accuracy of existing method is low, manufacturing deficiency is many.Require further improvement.
