Radiance 19" SXGA LED Solution
Datasheet:
Description
The RAD-190AUSX1 is part of ACI's new
RADIANCE
line of
LED sunlight readable display solutions. The RAD-190AUSX1 includes
modified panel ACD-AU190-1895 , LED driver ACI-E120250-1879, and input
cable
assembly 27-R0061 which provides maximum output current level to
properly drive the LED rails in this specific solution. The ACD-AU190-1895 panel consists of the AUO M190EG01 V2 19.0" SXGA 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 1.5 to 1.
Performance at given brightness levels1000 cd/m2 with 53 watts LED power
The modified display outline is identical to the standard CCFL equipped panel.
For most applications, satisfies sunlight readability goals.
