PT-3000
The 65550 support a wide variety of monochrome and color standard and high-res
passive STN and active matrix TFT/MIM LCD, and EL panels. For monochrome
panels, up to 64 gray scales are supported. Up to 4096 different colors can be
displayed on passive STN LCDs and up to 16M colors on 24-bit active matrix LCDs.
The 65550 offers a variety of programmable features to optimize display quality.
Horizontal and vertical stretching capabilities are also available for both text and
graphics modes for optimal display of VGA text and graphics modes on 800x600 and
1024x768 panels. Three selectable color-to-gray scale reduction techniques are
available for improving the ability to view color applications on monochrome panels.
The 65550 uses a variety of advanced power management features to reduce power
consumption of the display subsystem and extend battery life. Although optimized for
3.3V operation, the 65550's internal logic, memory interface, bus interface, and panel
interfaces can be independently configured to operate at either 3.3V or 5.0V.

3.1.7 Touch Panel Interface
Elo TouchSystems designed AccuTouch touchscreens with the harshest environments
in mind, so it’s no wonder they excel in reliability, durability and expected product life.
Impervious to environmental conditions such as liquid spills and splashes, humidity,
and washdown, these touchscreens provide the most contamination resistance
available on the market today. And AccuTouch touchscreens deliver drift-free
operation—for all 35 million touches of their life.
PT-3000 implements serial-type of touch panel system with mouse emulation. The
touch panel is connected internally to serial port COM 4, IRQ 5.
3.1.7.1 Key Features
• AccuTouch’s patented five-wire resistive technology provides unmatched accuracy
because of its inherently stable design. There’s no need for recalibration when
environmental conditions change.
• Enhanced scratch-resistant hardcoat yields protection against damage.
• AccuTouch can be activated with fingers, fingernails, stylus, gloved hand and credit
cards, while maintaining superb tactile feel.
• AccuTouch touchscreens are completely sealed against contamination and
moisture. This prevents fluid ingress through the air vent due to capillary action.
• Most cost effective resistive touchscreen chip. The AccuTouch COACh (Controller
On A Chip) is specifically designed for resistive touchscreen applications. The
COACh is a single chip solution that is compatible with all Elo touchscreen drivers.
