Nippon Leiz showcased backlight module for two-display phones

Nippon Leiz Co, Ltd exhibited at the FPD International 2003 its new back-to-back light emitting diode (LED) backlight for mobile phones that have a main LCD and a sub-LCD.

Thus far, many mobile phones have been employing two LED backlights, but with the new technology only one backlight is necessary. The backlight supports the 2-in. main LCD and the 1.2-in. sub-LCD.

Previously, if one backlight unit was used for both the main and sub-LCDs, the sub-screen became visible from the main screen. Nippon Leiz´s new optical design was optimized to solve this problem.

There are two kinds of new backlights: regular and brighter. Regarding the average brightness of a regular unit, the brightness of the main LCD is 1,500 nit, and that of the sub-LCD is 1,600 nit. The average brightness for the main LCD of the brighter unit is 1,900 nit, and that of the sub-LCD is 2,050 nit. The electric power consumption of both types is 210mW.

The regular one was commercialized on October 29, and the brighter type was showcased for reference, slated for commercialization in the spring of 2004.
