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.
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.

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.
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.
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.
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].
4 Video Signal Requirements 4.1 Video Input Lines The video signal connector that connects to the customer’s equipment is a female 15-pin connector in a high density 9-pin D-Shell housing. Pin number assignments are defined in Table 4, and physical layout as seen by the interface cable from user logic is shown in Error! Reference source not found. The "NC" positions of this connector are not used for any purpose.
defined as a level between 0-mv and 10-mv. The white state (full white) is dependent on the VGA controller driving the LC1200R. Maximum levels may range from 550-mv to 714-mv. Nominal 680-mv input voltage shall be defined as the default for supplier setup requirements. Displayed image intensity and colors will change linearly with the video analog input. This is necessary to provide a uniform user color change on the screen in response to a uniformly stepped analog input.

4.2.3 Mode Detection The polarity of incoming horizontal/vertical frequencies and synchronization pulses define the video resolution being presented. Video modes are listed in Table 5 Video Mode Definitions.

4.4 Timing and Frequency 4.4.1 Video, Horizontal and Vertical Sync Figure 6 illustrate video timing relationships the LC1200R operates within when the specified video mode (Table 5 Video Mode Definitions) is applied. Front Porch defines the time from end of active video data to the start of Horiz/Vert Sync Pulse. Back Porch defines the time from end of Horiz/Vert Sync Pulse to the start of active video data. Blanking is the total time comprising Front Porch, Back Porch and Sync Pulse time(s).

Note: For video mode 720 x 400 missing video rows and columns are allowed. This is a text mode only.
The LC1200R is not damaged by input voltages ranging from 0-vdc to 12.4-vdc. 5.3 Power On-Off Sequences The LC1200R will automatically return to normal operation upon resumption of power after a power loss. 6 User Controls 6.1 LCD Controller Board Controls The display comes from the factory adjusted for the supported modes. When using these modes, adjustment should not be necessary.
The Gain adjustment is to allow the full scale of the input video to be utilized. The direction of this adjustment will reverse when a limit is reached. For example, it will adjust from maximum to minimum, then reverse and go from minimum to maximum. The best way to make this adjustment is with a continuous gray scale pattern on the display. A proper adjustment will give continuous shading from black to white.
6.2.2 Max Bright Jumper The photodiode board can be removed from the system. When the photodiode board is unplugged the LC1200R will default to the minimum brightness mode. If the user would like to display to run at maximum brightness, the MAX BRIGHT, JP1, jumper must be inserted on the inverter board.
6.3 Dimming 6.3.1 Photodiode Board and Automatic Dimming Connector The photodiode board must be mounted in the user’s system so that the photodiode is exposed to the ambient light. In bright conditions, the LC1200R will adjust to maximum brightness. In dark conditions, the LC1200R will adjust to approximately 25% of the maximum luminance. Connector Pin Assignments are in Table 8 Table 8 Pin 1 2 3 Description Output from photodiode anode 5V input from the LC12F for photodiode cathode No connection 6.3.
The typical monitor brightness vs. ambient is as follows: Figure 9.

The DIM input will override any input from the photodiode board. Note that the photodiode board may be left disconnected if not used.

The jumper will force the LC1200R to maximum brightness unless the /DISABLE input is active. Use a 0.1 inch jumper such as Molex, part number 15-29-1024. 7 Monitor Performance 7.
