1 Introduction

This document defines the electromechanical parameters and operating characteristics for The
Planar Systems, Inc. LC1200R, Very High Bright, 12.1” Active Matrix Liquid Crystal Display (AMLCD)
based product. It is intended for operation as a component in a high ambient light, outdoor system.
The LC1200R has a scaleable video format capable of displaying a minimum of VGA (640 x 480)
through XGA (1024 x 768) input resolution.

The LC1200R can be driven directly from the standard analog video graphics adapter (VGA) output
on a personal computer (PC). It consists of a 12.1" viewable diagonal LCD panel with optical
elements, cold-cathode fluorescent backlight, backlight inverter board, and LCD controller board. A
tethered photodiode provides automatic brightness control. Cooling fans are provided to cool the
back of the LCD module. If used in direct sunlight, it is the system designer’s responsibility to provide
an enclosure that directs the airflow, across the front of the display. Two (2) chassis mounted
connectors at the rear provide for video signal and 12 V DC power input connections. The enclosure
is aluminum for added cooling and ease of installation.

vertically and 800 pixels or 1024 pixels horizontally, 600 lines or 768 lines vertically for the
VESA2 modes. Figure 4 defines the video signal timing requirements.

The LCD controller board will automatically program itself, sensing incoming
horizontal/vertical frequencies and sync pulse polarities to completely “fill” the active display
area of the LC1200R with the video resolution being presented. Section 4.2 defines
parameters for video resolution detection by the LCD controller board.

2.4 Cooling Fans

Four (4) thermostatically controlled cooling fans are provided to cool the rear of the display. The
thermostat is set to turn the fans on when the video board temperature reaches 30° C. If the display

is used in direct sunlight, airflow must be directed across the front of the display or the display LCD
fluid may reach its clearing point, then the LC1200R will become temporarily unreadable.

2.5 Connectors

There are four connectors supplied as an integral part of the LC1200R.

2.5.1 Video Signal Connector

The LC1200R unit includes a chassis mounted 15-pin female mini D-Shell connector (AMP
748390-5 or equivalent) with socket contacts at the rear of the LC1200R. It is shielded for
electromagnetic interference (EMI) purposes. Refer to Section 4.1 for electrical connections.

2.5.2 DC Power Input Connector

The DC power input connector is a chassis mounted 2-pin connector (Molex Mini Fit Jr
Header 5569 Molex p/n 39-30-0020) with pin contacts at the side of the LC1200R. The
connections are insulated to prevent accidental contact.

2.5.3 Photodiode Connector

A 3-pin connector, Molex p/n 22-03-5035, is provided on the inverter board. The connector
accepts the cable assembly provided with the product that attaches to the provided
photodiode board.

2.5.4 Dimming Control Connector

A 5-pin connector, Molex p/n 22-03-5055, provides an analog input that can override the
automatic photodiode dimming and allows the backlight to be shut down using an inhibit
input.

2.5.5 Button Board Connector

The Button board can be mounted remotely or removed for better access when mounted
into the larger system.

2.6 Interface Cables

The display is shipped with a remote photo-sensor and cable, removable button board, and 6 ft VGA
interface cable. No other interface cables are provided. An external power supply brick is available
for purchase from Planar Systems, Inc

.

2.7 Power Supply

The LC1200R does not ship with a power supply. It is recommended that the Planar Systems, Inc.
power adapter, part number 997-3066-00 (US) or 997-3067-00 (EU) be purchased with each unit.
Refer to Section 5 for power requirements.

2.8 LCD 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 spatial-temporal dithering reducing visual artifacts.

• 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.

2.9 Inverter 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

2.11 Button Board

The button board controls the user controls noted in Section 6.1 LCD Controller Board Controls It can
be removed or mounted in another area after initial adjustments are made.

Note 3: Slight background color changes are allowed depending on ambient temperature.
This phenomenon is reversible.

Note 4: High temperature operation assumes the use of an enclosure that properly directs the

Note 5: Upper operating temperature limit of 60°C is without solar loading.
Reference to "room ambient" is interpreted as 20°C - 25°C [68°F°- 77°F] and applies throughout this
