User interface platform for graphic-rich, colour touch screens

July 13, 2011 // By Julien Happich
andersDX's new 'DX1’ series of embedded displays provides a ‘drop-in’ solution for integrating small, touch TFTs with multiple interfacing options and support for graphic primitives. The embedded display platform significantly reduces the cost and time overhead of upgrading existing mono interfaces or implementing new product designs with high-performance next generation colour, touch interfaces.

The DX1 is conceived as a development path for small-to-medium volume, non-consumer device makers who prefer to focus in-house resources on core application development. It comprise carefully selected long-lifetime availability, optically advanced colour TFTs, pre-integrated with different touch options and all necessary driving electronics, backlight drivers and power supplies, to ensure optimal graphics performance. The mechanical and electrical integration overhead has been kept to a minimum through convenient mounting holes and multiple options for interfacing to the main application board. Combining an 80MHz ARM processor and 1MB of serial Flash for user data storage such as commands, macros, images and font files, the DX1 can connect to a device host processor via I2C, SPI, serial or RS485 interface.

The DX1 platform also incorporates two channels of 10 Bit A/D which can be used for interfacing analogue signals and a PWM and GPIO’s for controlling external peripherals. A complementary GUI software suite enables the quick design and development of different applications screens. These screens are then called on through an in-built command interpreter, whilst an ‘instant start’ capability provides a boot time of less than one second. The 3.5” QVGA TFT is available in either portrait or landscape mode and comes with ultra-wide viewing angle of 150°, left to right, with excellent optical clarity, high colour saturation, 450 cd/m2 brightness and extended operating temperatures of -30 to +85°C. Whilst the standard DX-1 offers a traditional 4-wire resistive touchscreen, users are encouraged to further optimise product performance by leveraging the andersDX FlushTouch front panel design service or by selecting a PCAP touch option, with their choice of coverlens.
