Introduction
LM130A-12C318 is a 12.1" high efficiency sunlight readable LCD module. The module consists of a Toshiba
LTM12C318lowtemperaturepoly-silicon(LTPS) TFTcolorLCDpanelandaLandmarkveryhighbrightness(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 25oC
 ±
 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.
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
