Abstract
For backlighting a direct view avionic liquid crystal display (LCD), a multi-channel true flat fluorescent lamp (T-FFL) has been designed an d developed. The design and development was accomplished through 1) el ectric field plot for various ratios of depth to height of the hollow cathode, 2) decrease of charge losses, 3) employment of internal diele ctric mirror, 4) monitoring of the penetration of internal positive co lumn, and 5) design of a constant current drive for T-FFL. A luminance of 3000 fL. with a luminous efficiency of 16.2 l/w has been achieved on a 3'' diagonal T-FFL.
