LM222-170EG01 - 17"
Sunlight Readable LCD Module
Introduction
LM222-170EG01 is a 17" sunlight readable LCD module. The module consists of an AUO G170EG01 TFT color
LCD panel and a Landmark VHB (very high brightness) backlight. The module is fully compatible, mechanically
and electrically, to Landmark LM177-170EG01 sunlight readable LCD module.
At the maximum backlight power of 37 Watts, the LM222-170EG01 module delivers 1,300 Cd/m2 (nits) of LCD
screen luminance. At this brightness level, the display is highly readable under bright ambient lighting including
direct outdoor sunlight. It is recommended that the Landmark BI320A inverter be used to operate the backlight in
this LCD module. With this inverter, the LCD screen luminance can be adjusted down to 7 Cd/m2 for night viewing.

Note 1: Please refer to AUO G170EG01 LCD Specification for detailed electrical specifications and general precautions.
Note 2: All data is measured at 25o C ± 2oC ambient temperature.
Note 3: Uniformity = (Lmax - Lmin) / (Lmax + Lmin) where Lmax (Lmin) is the maximum (minimum) luminance measured using a 10
mm diameter meter aperture over the LCD active area, except the last 10 mm area from the edges.
