LM151-121XH01 fiche technique
LM151-121XH01 - 12.1"
Sunlight Readable LCD Module
Introduction
LM151-121XH01 is a 12.1" sunlight readable LCD module with XGA (1,024 x 768) resolution. The module consists
of an Mitsubishi AA121XH01 TFT color LCD panel and a Landmark VHB (very high brightness) backlight. It has
the same foot print and uses the same mounting holes as the original AA121XH01 LCD.
At the maximum backlight power of 20 Watts, the LM151-121XH01 module delivers 1,700 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 BI200A inverter be used to operate the backlight in
this LCD module. With this inverter, the LCD screen luminance can be adjusted down to 9 Cd/m2 for night viewing.

Note 1: Please refer to Mitsubishi AA121XH01 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.
