Introduction
The Drucegrove DragonFly™ range of TFT displays are capable of showing elevator position, direction and emergency
messages in addition to other text, images and rich media. This allows the displays to be branded and customised
match the building they are installed in. The additional text and images can be static (ie building name, company
logo, etc), or dynamic based on the position of the elevator (ie individual floor tenancy information).
The TFT20 Series displays are self contained units with the display and driving electronics integrated into one
package. The screen sizes available are 4.3”, 5.7” and 7.0”, and they have the same built in message image library as
the FireFly™ TFT300 Series indicators.
For larger DragonFly™ displays, the TFT500 Omni Driver can be used. This is based on the same driving electronics as
the TFT20 series but boasts a more powerful processor with graphics accelerating and video decoding hardware, and
a DVI / HDMI output. Drucegrove supply a separate open frame TFT screen and a HDMI to DVI cable for connecting
the screen to the TFT500 Omni Driver. The screen sizes available range from 10.4” to 42”, in 4:3 standard, 16:9 wide
or 4:1 panoramic aspect ratios
The TFT20 Series and TFT500 can be networked via Ethernet, which opens up the possibility of streaming live news
headlines, weather, finance information, transport information (TfL, Nation Rail, bus times etc) and more from RSS
feeds.
Live video can also be displayed on displays driven from the TFT500 Omni Driver. The video is streamed digitally to
the display over Ethernet from either an IPTV source or an IP CCTV camera - either of which can be located anywhere
in the building. Being digital, a single video feed can be streamed to an unlimited number of displays without loss of
quality or the need for boosters or amplifiers.
DragonFly TFT20 Series TFT Position Indicators
Drucegrove’s DragonFly™ TFT20 Series Indicators are available in
three standard sizes: 4.3", 5.7" and 7.0". The displays are fully
customisable, and at their simplest level offer a wide choice of
colours, images, character fonts and arrow styles. They are available
with a choice of two different integrated drivers, the RE1 or the RE2.
The RE1 offers basic drawing options with no animation or video. The
RE2 has hardware accelerated graphics allowing smooth animation,
alpha blending and live video playback.
The position indicators may be configured for elevator car or landing displays, and are capable of showing up to
three character floor designations, car direction arrows, hall lantern arrows, full screen messages and pictograms.
They are fully compatible with the Drucegrove 2-Wire™ System and
OTIS
® Serial Data, and may also be used as
stand-alone position indicators with binary, Gray or discrete wire-per-floor inputs.
Every aspect of the display can be configured, and special display content can be configured to show or change at
certain floors, for certain message responses, or even for a specific time of day or date.
The position indicators can be configured over a LAN via a standard web browser, or alternatively the on-board
micro SD card can be removed and reconfigured freely from any computer.
