EL640.480-AG1 Series VGA Display
The EL640.480-AG1 series displays are 8.1" diagonal VGA products which offer
designers an affordable solution in demanding applications where superior visual
performance and environmental ruggedness are critical. Utilizing Planar’s
proprietary ICEBrite (Integrated Contrast and Brightness Enhancement)
technology, these displays excel in ambient light environments ranging from
dark to nearly sunlight-bright. This technology achieves very high contrast and
exceptionally clear images using a common 8-bit FPD-type interface compatible
with most LCD video controller chips.
The EL640.480-AG1 ET (AG ET) is the extended-temperature version of the
EL640.480-AG1 (AG) display. See temperature specifications on page 14 for more
information. The EL640.480-AG1 ET LP (AG ET LP) is the low-profile version of the
AG1 ET.
Through simple design and advanced manufacturing technologies, Planar’s new
VGA display family brings the visual performance and image quality of EL into
cost-sensitive applications that have up to now been limited by the performance
of LCD displays.
Features and Benefits
• Excellent visual performance:
High brightness and contrast
Wide viewing angle > 160°
• Reliable, long operating life
• Extremely rugged and durable
• Low EMI emissions
• Rapid display response < 1 ms
• Low power design
Options
Anti-glare and conformal coating options are available on this display.
The anti-glare option adds an anti-glare film to the front of the display to reduce
specular reflections (see Application Note 135 for more information).
The conformal coating option adds a protective layer to the display for
applications in which the display may be subjected to high humidity, dust, or salt
mist (see Application Note 122 for more information).
A locking connector, which is standard in the AG ET version, is optional with the
AG display.

Interface Information
This dual scan LCD-type video interface provides a low cost, flexible method for
controlling display brightness and power consumption. Many off-the-shelf
chipsets are available for interfacing to flat panel displays. If your application does
not require chip-level integration, there are many vendors that can supply board-
level solutions for serial control, PC104, ISA, and many other interfaces.
Planar Application Note 116 summarizes some of the interfacing options that
have been used in the past with EL VGA displays.
Video Input Signals
The end of the top line of a frame is marked by S, scan start up signal as shown in
Figure 2. The end of each row of data is marked by CP1 as shown in Figure 2 and
Figure 3.
Input signals UD3—UD0 contain the video data for the upper screen and signals
LD3—LD0 contain the data for the lower screen. For example, four pixels (UD3—
UD0) are sent to row 1 at the same time as four pixels (LD0—LD3) are sent to row
241. This results in eight pixels sent on each cycle of video clock CP2. Pixel
information is supplied from left to right and from top to bottom. Video data for
one row is latched on the fall of CP1 (Figure 4).
