The electrooptic characteristics of 32-inch multichannel-structured, mercury-type flat fluorescent lamps have been investigated in detail. The luminance and the lamp current/voltage have been monitored by changing the driving conditions such as duty ratio, backlight conditions. It was found that the efficiency became the maximum at the duty ratio of 50 % with a nearby metal plate.

A flat fluorescent lamp (FFL) developed as a light source for LCD TV backlight was used as a light source for general lighting application and its electro-optical characteristics were measured and evaluated. The channels of FFL were formed from a flat glass at high temperature by using a mold. The performance of FFL with lighting future was shown to improve by optimizing the channel profile of FFL. In this paper, the brightness efficiency of FFL with lighting fixture was evaluated and compared with that of the hot cathode fluorescent lamp (HCFL), the major light source for general lighting. The optical efficiency of FFL with future was shown to be 72.7[1m/W].

Flat fluorescent lamp(FFL) is used as a light source for LCD TV backlight and is composed of many discharge channels but each channel may not be turned on simultatneouly especially at cold temperature. The simultaneous start of each lamp channels of FFL was accomplished by driving FFL with specially designed voltage and currnet waveforms without sacrificing the inverter efficency.

A two-dimensional fluid simulation code has been developed in order to investigate discharge phenomena and to improve plasma luminous efficiency in a Hg flat fluorescent lamp (FFL) for an LCD backlight unit. In this study, the method of a two-dimensional fluid simulation for FFL is explained and the simulation results of Hg-Ar-Ne mixture gas are presented for the enhancement of the luminance efficiency. The effects of various parameters, such as driving voltage, frequency, and gas mixture ratio, are investigated. The luminance efficiency increased with increasing fraction of mercury but the increasing fraction of argon did not affect the efficiency much.

In this study, flat fluorescent lamps (FFLs) having surface discharge structures was fabricated by screen printing technique and were studied using spectraradiometer and square pulse power supply. Two types of FFLs having different shapes of electrodes (crosstype and line-type structure) were compared with variation of discharge shape and mixed gas ratio.
