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. 2 Basic Construction 2.1 LCD Display 2.1.1 LCD Panel ­ Physical Image Characteristics The LC1200R incorporates an matrix display with the following features: LCD Size: Active Area: Pixel Format: Pixel Pitch: Pixel Arrangement: 307.5mm [12.11in] diagonal 246.0mm [9.69in] by 184.5mm [7.26in] 800 (H) x 600 (V) (1 full color pixel = R + G + B dots) 0.3075mm [0.012in] horizontal x 0.3075mm [0.012in] vertical R,G,B vertical stripe LC1200R User's Guide 021-0183-00 Rev A 4 of 29 2.1.2 Display format The LC1200R is compatible with IBM VGA1 and VESA2 video standards. Its operating frequency range is 31.5 kHz to 56.5 kHz horizontal; 60 Hz to 72 Hz (non-interlaced) vertical. Specific video resolutions supported in Table 1 Table 1 Video Resolution 640 x 400 640 x 480 720 x 400 800 x 600 1024 x 768 Number of Bits/Color 6 6 6 6 6 Number of Colors 262,144 262,144 262,144 262,144 262,144 For IBM VGA1 modes, the LC1200R will accept 640 pixels horizontally; 400 or 480 lines 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. Note: IBM VGA1 modes with border and the 720 x 400 video resolutions are excluded from completely filling the active display area horizontally. Only the first 640 pixels will be displayed. 2.2 Weight The LC1200R has a lightweight aluminum enclosure and does not exceed 1.8 kg (4 lbs) 2.3 Mechanical Size: 301mm x 265mm x 63 mm (11.9" x 10.4" x 2.5") See Planar Mechanical Outline drawing 076-0549-00 for more detail Figure 1.

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. LC1200R User's Guide 021-0183-00 Rev A 7 of 29 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 LC1200R User's Guide 021-0183-00 Rev A 8 of 29 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. 3 Environmental 3.1 Temperature and Humidity The LC1200R withstands operating and storage environmental conditions listed in Table 2. Table 2 General Operating Temperature Relative Humidity Note 1: Note 2: Tair < Tair > Tair @ Tair @ 0°C to 60°C [32°F to 140°F] Note 1 Shipping and Storage Comments Note 2,3,4,5 Without Condensation -20°C to 60°C [-4°F to 140°F] Note 1 Tair is defined as ambient air temperature surrounding the LC1200R. 32°C 32°C -20°C 60°C : 95% RH maximum. : Absolute humidity content not to exceed 100% at 32oC. < 48 hours < 168 hours Note 3: Slight background color changes are allowed depending on ambient temperature. This phenomenon is reversible. Note 4: fan airflow Note 5: High temperature operation assumes the use of an enclosure that properly directs the 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 specification unless otherwise noted. For product reliability predictions, the assumed temperature profile is: Table 3 Operating Time 5% 90% 5% Temperature 0°C [32°F] 30°C [86°F] 60°C [140°F] LC1200R User's Guide 021-0183-00 Rev A 9 of 29 3.2 Direct Sunlight Operation This monitor will absorb approximately 45 W of solar power on the front surface of the display in a typical setup when facing the sun directly. It is the integrator's responsibility to design a system that cools the front surface adequately. Otherwise, the display's LC material will overheat and temporarily phase change. The display will temporarily become black and unreadable. 3.3 Altitude Maximum operating altitude is 3,000 meters [9,850 feet].
