An External-Electrode Flat-Panel Lamp for LCD Back-Lighting

Abstract

In this paper, a flat back-light in which has no electrodes was developed. This back-light was fabricated by two flat glasses in which the pure Xe (at pressure of 150 Torr) was sealed, with a layer of commercial water on the out surfaces of the glasses as the external electrodes, where the glass with thickness of 1.2 mm was used as the dielectric barrier. The white light was available by exciting the phosphor layer with the plasmas introduced by high-frequency voltage, whose luminance was 4000 cd/m2, accompanied with the lighting homogeneity over than 92 %. The effects of driving voltage and the discharge space in the samples on the lighting characteristics of the back-light were comprehensively evaluated.
