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-of-
sale 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.
