1.0 Introduction

This document defines the electromechanical parameters and operating characteristics for a 12’1” Active Matrix Liquid Crystal Display (AMLCD) based product, hereafter referred to as the Monitor. It is intended for operation in high ambient light, outdoor environment. The Monitor has a scaleable video format capable of displaying a minimum of VGA (640 x 480) through XGA (1024 x 768) input resolution.

The Monitor can be driven directl y from the standard analog Video Graphics Array (VGA) output on a personal computer (PC). It consists of a 12.1" viewable diagonal LCD Panel with optical elements, ColdCathode Fluorescent Backlight, Backlight Inverter Board, and LCD Controller Board. Cooling fans provide temperature stabilization within the Monitor’s operating environment. Two (2) chassis mounted connectors at the rear provide for video signal and DC power input connections. These components will be mounted in a fully enclosed chassis.

1.1 Display Format The Monitor is compatible with IBM VGA1 and VESA2 video standards. Its operating frequency

range is 31.5 KHz ?56.5 KHz horizontal; 60 Hz ?72 Hz (non-interlaced) vertical. Specific video resolutions supported are as follows:

Video Resolution Number of Bits/Color Number of Colors

640 x 400 6 262,144 640 x 480 6 262,144 720 x 400 6 262,144 800 x 600 6 262,144

1024 x 768 6 262,144

For IBM VGA1 modes, the Monitor 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 9 defines the video signal timing requirements.

The LCD Controller B oard will automatically program itself, sensing incoming horizontal/vertical frequencies and sync pulse polarities to completely “fill” the active display area of the Monitor with the video resolution being presented. Section 4.4.1 (Video Mode Definition s) defines parameters for video resolution detection by the LCD Controller Board.

Note: IBM VGA1 modes with border and the 720 x 400 video resolution are excluded from completely filling the active display area horizontally. Only the first 640 pixels will be displayed.

2.0 Basic Construction

2.1 Weight

Monitor weight does not exceed 5 Kgs (11 lbs).

2.2 Mechanical Mounting Requirements Per Planar Mechanical Outline drawing 074-0666-01

2.3 Monitor Electronics Electronic components requiring heat sinks are installed independent of the Monitor enclosure.

That is, its sheet metal chassis is not used as a heat sink for any electronic component.

2.4 Cooling Fan Cooling fans are installed to maintain appropriate internal operating temperatures when the

Monitor is subjected to its operating environment of Section 3. Forced air convection is used to cool the LCD Panel (front and back).

2.5 Vandal Glass The Monitor is designed to operate with a vandal glass 289 mm x212 mm x 10 mm in place. This

vandal glass in not provided with the Monitor.

2.6 Air Filtration An air filter mesh is included to prevent ingress of insects and ensure continual flow of cooling air

within the Monitor. The air filter mesh is externally accessible for cleaning.

2.7 Connectors There are two (2) connectors supplied as an integral part of the Monitor.

2.7.1 Video Signal Connector

2.7.2 DC Power Input Connector

The Monitor 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 Monitor. It is shielded for electromagnetic interference (EMI) purposes. Refer to Section 4.1 for electrical connections.

The DC power input connector is a chassis mounted 2-pin "MAT?N?LOK" style connector (AMP 1-480699-0 or equivalent) with pin contacts at the rear of the Monitor. Connections are insulated to insure no accidental contact.

Title: Product Specification: LC12 High-Bright Monitor Page 5 of 24 Document Number: 023-0284-01 Revision: A

2.8 LCD Controller Board

The LCD Controller Board incorporates components necessary to drive the LCD Panel (Section

6.7). 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.

2.9 Grounding

Two (2) types of ground are provided: Chassis and Signal ground.

2.9.1 Chassis Ground

The chassis ground is a conductor that is grounded to the earth within user circuitry. It is not used for current carrying purposes. It is used only for non-current carrying purposes such as electromagnetic compatibility (EMC).

2.9.2 Signal Ground

Signal ground is electrically connected to chassis ground via the LCD Panel. However, there are no DC currents carried through this interconnect.

2.10 External And Internal Controls

A single external “Video Gain” control compensates for the white state (full white) video signal level range specified in Section 4.2.1 in achieving sixty-four (64) shades of gray.

External horizontal and vertical image positioning control(s) are provided to accommodate for the undefined delay between sync and video data edge referred to as Front Porch / Back Porch in Figure 9.

Note 3: Slight background color changes are allowed depending on ambient temperature.

This phenomenon is reversible.

Note 4: Tair @ -30°C : 15% RH (exterior face of Vandal Shield) Tair @ 54°C : 100% RH (exterior face of Vandal Shield)

Note 5: Upper operating temperature limit of 60°C is without solar loading. See section 3.2

for operating temperature conditions with solar load.

Reference to "room ambient" is interpreted as 20°C - 25°C [68°F -? 77°F] and applies throughout this specification unless otherwise noted.

Excluding the exterior face temperature range of the Vandal Shield (Note 4), this Monitor will not be subjected to environments outside of the limits of Table 1.

For product reliability predictions, the assumed temperature profile is:
