Plasma display panel using color filters to improve contrast
Abstract:
A plasma display panel is provided. The plasma display panel includes a front substrate; a rear substrate arranged to face the front substrate, a dielectric layer arranged between the front and the rear substrates and at least a portion of the dielectric layer having a first color, plurality of barrier ribs arranged between the front and the rear substrates and at least a portion of the plurality of barrier ribs having a second color, plurality of light absorbing layers arranged between the front substrate and the plurality of barrier ribs, wherein the first and the second colors are subtractive-mixed with each other. The dielectric layer and the plurality of barrier ribs are colored with two complementary colors that essentially filter out nearly all light. Accordingly, it is possible to reduce outdoor daylight reflection and improve image contrast.
