Functions/Characteristic by Layer
NO Item Rating
1 ITO Electrode (Maintain /Scanning Electrode) Within discharge cell, it causes discharge and maintains it. Visible light transmissivity should be high. The lower the electrode resistance, the better.
2 BUS Electrode Relatively large resistance value compensation of transparent electrode ¡æ The same voltage supply in all(mostly) discharge cell
3 Transparent Dielectric Discharge current constraint ¡æ Glow discharge maintenance
Wall charge accumulation ¡æ Memory function, voltage decrease
Required SPEC. : High internal voltage, high visible light transmissivity
4 Protective layer (MgO) Transparent dielectric layer protection from ion collision
Secondary electron release ¡æ Discharge voltage decrease
5 Address Electrode The lower the electrode resistance, the better
6 Lower Board Dielectric Layer Address electrode protection, high insulation destruction strength, and high light transmissivity are advantageous
7 Barrier Rib A certain space for discharge should be insured in each discharge cell and RGB phosphors should be isolated not to be mixed.
A fixed height should be formed over the whole area. Black layer on top: To increase Contrast
8 Phosphor Layer It receives (vacuum) ultraviolet rays generated through discharge and transforms or releases them into (each RGB) visible rays. Excellent light transformation efficiency ¡æ High brightness(In particular , B)
Excellent color purity ¡æ High color reproducibility provided For the improvement of discharge efficiency, high efficiency phosphor development is required.
