Radiance 15" XGA LED Solution

Datasheet:

Description

The RAD-150CHXG1 is part of ACI's new RADIANCE line of LED sunlight readable display solutions.  The RAD-150CHXG1 includes modified panel ACD-CH150-1904 , LED driver ACI-E120250-1918, and input cable assembly 27-R0061 which provides maximum output current level to properly drive the LED rails in this specific solution.  The ACD-CH150-1904 panel consists of the Chi Mei panel G150X1-L03 15.0" 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 1.5 to 1.

Performance at given brightness levels

1700 cd/m² with 23 watts LED power

The modified display outline is identical to the standard CCFL equipped panel. 
For most applications, satisfies sunlight readability goals.
