37.2: A Mercury‐Free Cold Cathode Fluorescent Lamp for LCD Backlighting

Hidehiko Noguchi; Hidetoshi Yano

A mercury-free cold cathode fluorescent lamp which is suitable for the backlighting of a car-navigation display, has been developed. This lamp consists of one inner electrode and one outer electrode. By optimizing the structure of the electrode and the driving condition, a high luminous flux and a wide dimming control were achieved. The total luminous flux of this lamp reached to about 50% as much as that of a conventional Hg-type CFL.

A mercury‐free backlight with Xe CFLs for automotive navigation displays

Hidehiko Noguchi; Hidetoshi Yano; Ryuji Tsuchiya; Hirozumi Nakamura

A mercury-free backlight in which Xe-type small-diameter CFLs were installed has been developed. The backlight is 7 in. wide and 10 mm thick. The luminance of this backlight is 6000 cd/m 2 at 6.5 W, the light-output stability time is within 1 sec, and the dimming capability is from 100% to 1% over a wide temperature range. Therefore, it is suitable for an automotive-navigation display.

40.2: A Mercury-free Backlight with Xe-CFLs for Car-navigation Display

Hidehiko Noguchi; Hidetoshi Yano; Ryuji Tsuchiya; Hirozumi Nakamura

A mercury-free backlight in which Xe-type small diameter CFLs are installed, has been developed. Backlight dimension is wide 7 inches and 10 mm in thickness. The luminance of this backlight is 6,000 cd/m2, light output stability time is wthin 1 second, and dimming capabililty is from 100% to 1% over the wide temperature range. Therefore, it is suitable for a car-navigation display.
