Radiance 22" WSXGA+ LED Solution
Datasheet:
Description
The RAD-220AUWS+1 is part of ACI's new RADIANCE
line of
LED sunlight readable display solutions. The RAD-220AUWS+1 includes
modified panel ACD-AU220-1935 , LED driver ACI-E120280-1942, and input
cable
assembly 27-R0061 which provides maximum output current level to
properly drive the LED rails in this specific solution. The ACD-AU190-1935 panel consists of the AUO G220SW01 V0 22.0" WSXGA+ 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 TBD to 1.
Performance at given brightness levels
800 cd/m2 with 48 watts LED power
The modified display outline is identical to the standard CCFL equipped panel.
For most applications, satisfies sunlight readability goals.
