Introduction
LM130A-12C318 is a 12.1" high efficiency sunlight readable LCD module. The module consists of a Toshiba
LTM12C318 low temperature poly-silicon (LTPS) TFT color LCD panel and a Landmark very high brightness (VHB)
backlight packaged in a compact sized, edge mount case with extremely narrow boarders outside the active area. The
LM130A-12C318 is mechanically compartible to Landmark 12.1" LM123-12DG11 sunlight readable LCD module.
At the maximum backlight power of 12 Watts, the LM130A-12C318 module delivers 1,350 Cd/m
2 (nits) of LCD
screen brightness. At this brightness level, the display is highly readable under direct sunlight. In addition, the color
tone of the “White” displayed on the LCD screen closely matches the color of normal sunlight. With a wide dimming
range inverter, the screen brightness can be adjusted down to less than 8 Cd/m
2.
The LM130A-12C318 LCD module displays a superb color image at 1024 x 768 (XGA) resolution over ambient
illumination levels ranging from total darkness to full bright sunshine, making it highly suitable for various outdoor
applications.
Note 1: Please refer to the Toshiba LTM12C318 data sheet for detailed LCD electrical specifications and general precautions
Note 2: All data is measured at 25
o
C ± 2
o
C ambient temperature.
Note 3: Uniformity = (Lmax -Lmin)/ (Lmax +Lmin) whereLmax (Lmin) is the maximum (minimum) luminance measured usinga 10
mm diameter meter aperture over the LCD active area, except the last 10 mm area from the edges.
Note 4: The positve angles are along the 6:00 & 3:00 directions and the negative angles are along the 12:00 & 9:00 directions
