Radiance 12.1" SVGA LED Solution
Datasheet:
Description
The RAD-121NCSV1 is part of ACI's new
RADIANCE line of
LED sunlight readable display solutions. The RAD-121NCSV1 includes
modified panel ACD-NC121-1862, LED driver ACI-1903, and input cable
assembly 27-R0066 which provides maximum output current level to
properly drive the LED rails in this specific solution. The
ACD-NC121-1862 panel consists of the NEC NL8060BC31-41C 12.1" SVGA 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 2.8 to 1.
Performance at given brightness levels
1050 cd/m2 with 6.0 watts LED power
The modified display outline is identical to the standard CCFL equipped panel.
For most applications, satisfies sunlight readability goals.
