2.7Power Supply
The LC1200R does not ship with a power supply. It is recommended that the Planar Systems, Inc. power adapter, part number
2.8LCD Controller Board
The LCD controller board incorporates components necessary to drive the LCD panel. Accepting VGA and VESA video standards (Section 1.2), these video signals are digitized and processed for the LCD panel. Due to the LCD panel’s fixed video resolution (800 x 600), the LCD controller board will perform independent horizontal and vertical zoom and shrink scaling of specified video resolutions less than or greater than the LCD panel’s video resolution to fully accommodate the LCD panel’s capability.
Magnification or reduction of specified video resolutions to match the native LCD panel’s resolution incorporates scaling algorithms minimizing aliasing and image distortion. The LCD controller board includes the following characteristics:
•Per pixel scaleable filters providing text sharpening and graphics smoothing for improved image quality.
•Color depth enhancement by performing
•External controls. See User Controls (Page 18) for more information.
There are 5 connectors for 12 V fans located on the controller board. They are attached to a 30º C thermostat.
2.9Inverter Board
The inverter PCB drives the LC1200R’s 6 cold cathode fluorescent lamps (CCFL). It is capable of automatic brightness control of the backlight. See User Controls (Page 17) for more information on the dimming functions.
There are 4 connectors to power 12 V fans on the inverter PCB. They are on constantly.
2.10 Photodiode Board
A photodiode (Siemens BPW21) mounted on a separate circuit board is provided for sensing the ambient light conditions. A cable (40 cm in length) is connected from the photodiode board to the inverter board on the LC1200R.
Size: approximately 1 x 3 cm with two 3mm diameter mounting holes. Refer to mechanical outline drawing for details
