LC640.480.21-065 Display
The LC640.480.21-065 is a 6.5-inch diagonal VGA active matrix liquid crystal display (AMLCD) designed to meet the demanding SAE specifications for the transportation industry. This display is ideal for a variety of industrial applications, such as point-ofsale and outdoor kiosks. With a typical brightness of 1000 nits, this sunlight-readable display offers high contrast in bright environments along with a wide dimming range for nighttime operation. With its modular design, this display is perfect for mobile computing and rugged applications where a high-performance embedded display is required. AMLCD Panel: The panel is a color active matrix LCD module incorporating amorphous silicon TFT (thin film transistor) technology with wide viewing angle characteristics. The video interface is digital, 6-bits per color, which allows up to 262,144 different colors. Backlight Module: The backlight assembly contains six high-efficiency cold cathode fluorescent lamps (CCFL), temperature sensors, and lamp heaters. All the components are mounted to a single circuit board. The CCFLs are heated at low temperatures to increase their luminance and extend their life. Located in front of the backlight module are several diffusing and brightness-enhancement films. Inverter Module: This assembly contains the backlight inverter electronics, microprocessor, heater control circuitry, and input/output connectors. All the components are mounted to a single circuit board. The microprocessor controls the inverter, heater, and dimming functions. The dimming functions include manual analog and automatic control based upon ambient light. Ambient Light Sensor: The ambient light sensor can remain attached to the display or mounted remotely using a cable. Video Interface: Standard VGA TFT interface is digital 6-bit RGB.
Features and Benefits
1000 cd/m2 typical luminance for sunlight-readability 3:1 contrast @ 100K Lux ambient for outdoor daylight use Wide +35/-45° vertical / ±50° horizontal viewing angle 300:1 digital dimming for efficient control over a wide range of ambient light 18-bit (6 bits per color) video interface for wide color range (262,144 colors) 30,000 hours MTBF for long service-free operating life Durable and lightweight for rugged conditions Convection cooling for operation without cooling fans Modular design for easy field replacement of backlight and inverter Automatic thermal management at low and high temperature extremes

Installation and Handling
Do not drop, bend, or flex the display. Do not allow objects to strike the surface of the display.
Mounting the Display
To maximize shock and vibration performance, the display must be properly mounted using all four mounting hole locations. There are two recommended mounting configurations. Appropriate changes to these mounting configurations may be needed to meet specific requirements or applications. Table 1 below lists the recommended mounting hardware.
Table 1. Mounting Hardware.
Screw Washer Tightening torque
M2.5 SS phillips-head or #4 SS phillips-head Lockwasher, split type 4 oz-in \ 2.8x105 dyne cm
Mounting Display Face Down
Standoff spacers or bosses with a minimum height of 3.0 mm must be used at all four mounting locations to prevent binding and deflection of the display.
Mounting Display Face Up
Standoff spacers or bosses with a minimum height of 33.0 mm must be used at all four mounting locations to prevent binding and deflection of the display.
Thermal Control
Several thermal sensors located on the backlight module allow the display to operate safely at temperature extremes. At low ambient temperatures, heaters on the backlight module warm the lamps to a safe temperature before energizing the lamps. This coldstart routine extends the life of the lamps and increases the luminance at low temperatures. During the warm up period, pin 39 on the input connector is set low. At high ambient temperatures, the luminance will gradually be reduced to maintain acceptable temperatures on the inverter module. If the temperatures remain above the acceptable level after the luminance has been totally reduced, then the inverter will shut down. During the luminance reduction period, pin 40 on the input connector (J1) is set to low.
Isolation and Air Gap
The display generates high voltage AC to drive the CCFL tubes. High voltage is present at numerous points on the backlight and inverter module that forms the rear surface of the display, so your application should not place metal too near the module. In the interests of both high voltage isolation and airflow for cooling, it is recommended that an air gap of .197" (5 mm) or greater be maintained behind the display.

Ambient Light Sensor Clearance
Two backlight dimming modes utilize automatic brightness control. If the display is to be operated in either of these modes, the ambient light sensor located on the front bezel must be unobstructed. If the sensor is placed behind the same protective window as the display active (viewing) area, the sensor operation may be affected due to light scattering and reflections from display-generated light coupling to the sensor via the window.
Cable Length
Due to the high frequencies present on the video interface, unterminated video cable lengths of more than 12 inches (300 mm) are discouraged.
Cleaning
Care should be taken to minimize scratching. Clean the display front with a dry, soft cloth such as a professional photographic lens cleaner. Disposable cleaning cloths are recommended to minimize the risk of inadvertently scratching the display with particles embedded in a re-used cloth. Particular care should be taken when cleaning displays with polarizers or anti-glare and anti-reflective films. These films may delaminate if exposed to certain chemicals.
Avoiding Image Retention
Image retention may occur when a fixed pattern is displayed for a long time. Use a screen saver or image inversion to avoid image retention on the display.

Specifications
Performance characteristics are guaranteed with the display at room temperature (25 °C) and with the operating voltage within specifications, unless otherwise specified. Optical performance is referenced to screen center at normal incidence with a full white screen display and the backlight at maximum luminance, 60Hz LCD frame rate, unless otherwise specified.

Power Sequencing (LCD)
When performing power sequencing: · Ensure the supply voltage for input signals is the same as for VCC. · Apply VCC within the LCD operation period. When the backlight turns on before LCD operation or the LCD operation turns off before the backlight turns off, the display may momentarily become white. · When the power is off, keep whole signals (Hsync, Vsync, CLK, DE, and DATA) low level or high impedance.
