Radiance 12.1" XGA LED Solution
Datasheet:
Description
The RAD-121NCXG1 is part of ACI's new
RADIANCE line of
LED sunlight readable display solutions. The RAD-121NCXG1 includes
modified panel ACD-NC121-1875 , LED driver ACI-1903 and input cable
assembly 27-R0067 which provides maximum output current level to
properly drive the LED rails in this specific solution. The
ACD-NC121-1875 panel consists of the NEC NL10276BC24-13C 12.1" XGA TFT
Active Matrix color display modified with a high performance white LED
backlight. The resulting performance exceeds that of the standard CCFL
equipped backlight by 1.8 to 1.
Performance at given brightness levels
1000 cd/m2 with 8.6 watts LED power
The modified display outline is identical to the standard CCFL equipped panel.
For most applications, satisfies sunlight readability goals.
