LC640.480.33-AC Display
The LC640.480.33-AC is a 1000 nit 10.4" diagonal VGA color AMLCD flat panel
display module intended for commercial applications requiring outdoor viewability and
long life. Special attention to the total backlight design gives the display a wide, “singleBEF” viewing angle while maintaining luminance efficiency greater than 45 nit/W.
The display is convection cooled and does not require a fan, yet features a wide
operating temperature range. It is lightweight, compact, and rugged, and includes an
integrated inverter in a package approximately one inch thick. With fast cell response
and an 18-bit (6 bits per color) video interface, this display can show full motion video
images.
The LC640.480.33-AC is designed, tested, and characterized as an integrated system
made up of two subassemblies. The LCD subassembly includes a sealed optical cavity,
and the backlight/inverter subassembly includes a cold cathode fluorescent (CCFL)
backlight and inverter. Due to the sealed optical cavity, the backlight subassembly may
be replaced without exposing the back of the LCD cell and optical films to airborne
contaminants.
Features and Benefits
♦ 1000 nit typical luminance for sunlight-readability
♦ 3:1 contrast @ 100K Lux ambient for outdoor daylight use
♦ Wide +40/-60° vertical / ±70° horizontal viewing angle
♦ 100:1 digital dimming for efficient control over a wide range of ambient light
♦ 18-bit (6 bits per color) display interface for wide color range (262,144 colors)
♦ 30,000 hours MTBF for long service-free operating life
♦ Durable and lightweight enclosure for rugged conditions
♦ Convection cooling for operation without cooling fans
♦ 3H diffuse hard coated front surface for scratch protection
♦ Modular design for easy field replacement of backlight and inverter
♦ Automatic shutdown at low and high temperature extremes for product safety

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 as shown in Figure 1 using the hardware listed in Table 1 below.
Appropriate changes to these mounting configurations may be needed to meet specific
requirements or applications.

Mounting Display Face Down
Standoff spacers with a minimum height of 0.102" (2.59 mm) must be used at all four
mounting locations to prevent binding and deflection of the display. Threaded studs
anchored in a bezel would be a design variation of this mounting option.
Mounting ECA Face Down
When mounting the display with the mounting screws installed from the viewing side, it
is not necessary to incorporate a flat washer. Provide for proper vent clearance and an air
gap/isolation allowance of 0.197" (5 mm) or better as described below.
LC640.480.33-AC Operations Manual (OM600-01)4
Vent Clearance
The LC640.480.33-AC display is a wide temperature display utilizing convection
cooling. It is imperative to allow ambient air unrestricted access to the cooling vents in
order to reliably operate the display at high temperatures
The vents for the lamp cavity are along the top and bottom edges of the display with the
openings facing the rear. The vents for the inverter cavity are along the top and bottom
faces of the display: four along the top surface and four along the bottom surface. Refer
to the mechanical outline drawing in Figure 15 for vent locations.
Isolation/Air Gap
The display generates high voltage AC to drive the CCFL tubes. High voltage is present
at numerous points on the backlight/inverter ECA which forms the rear surface of the
display, so your application should not place metal too near the ECA. 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 (ABC). 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 two feet (600 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 and with the backlight at
maximum luminance unless otherwise specified.
