Anders – QVGA TFT evaluation kit reduces development timeOct 20 2005 - Design & Manufacture [More Design & Manufacture Articles]
An evaluation kit, designed to significantly reduce the time-to-market of
applications using Toppoly´s 2.8″ and 3.5″ QVGA LTPS (Low Temperature
Polysilicon) TFT displays, has been introduced, by Anders.
Using the QVGA TFT Kit, engineers will typically get the display working
with their controller board within approximately one day, eliminating the
need to design their own interface board. It combines a 2.8″ or 3.5″ LTPS
display and integrated touch screen option with an interface board and all
of the cables and documentation needed to drive the display from a
microcontroller or TFT controller board. Target applications include data
collection devices, industrial handhelds, portable GPS systems, mobile
gaming, and other portable battery powered devices, says the company.
The kit comprises a 2.8″ or 3.5″ Toppoly QVGA display with optional
integrated resistive touchscreen and an Anders AED523 Interface Board. Full
documentation including application notes is also included helping designers
to easily connect their SBC or controller to the industry standard 40-way
PCB header connector. All necessary voltage levels for the display and LED
backlight are derived on board from power drawn through the connector, so
setting up and evaluation of images displayed on the screen can start
immediately. The board has a separate connector with orientation link
options for the touchscreen.
The company also offers a complete Windows CE 5.0 Hardware development
platform comprising the above hardware together with an Intel XScale PXA255
System-on-Module (SoM), Anders-designed baseboard, cables, Windows CE 5.0
and Software Development Kit. With the addition of a keyboard, mouse and
power supply this provides a ready to use development platform complete with
a working display and touchscreen.
Users can also outsource all aspects of their XScale and TFT development and
integration effort to Anders´ recently launched custom development service,
freeing their own design staff to focus on the application specific product
features that will bring them their market advantage.
Toppoly Optoelectronics´ transflective LCDs use advanced LTPS (low
temperature poly-silicon) technology to deliver better contrast ratios and
higher brightness and pixel density than conventional amorphous silicon TFT
displays. In addition, the use of LTPS technology and other techniques such
as chip on glass (COG) and system on panel (SOP) for very high levels of
integration minimises external component and contact count, simplifies
application design, and improves reliability.
Each unit provides a palette of 262k colours, high colour saturation and
wide viewing angles for both portrait and landscape viewing modes.Electropages - Electronics Components News, From Leading Electronics Distributors. More news from Anders
