Just a few months after ELECTRONIC ASSEMBLY launched its EA uniTFT product family, it is already being expanded with the presentation of a new display variant with a diagonal screen measurement of 10.1 inches at embedded world in Nuremberg. Developed in-house, the new intelligent display modules with object graphics open up a wealth of new options for the user. Design engineers and systems integrators benefit from considerably shorter development times and gain significantly more flexibility. As a result, the modules open up a whole raft of new options for developers and users.
The new EA uniTFT101 makes it remarkably easy to combine, modify and adapt a great many objects to a particular need. All objects can be positioned, rotated and zoomed in as required on the screen. Attributes such as transparency and color can be assigned also. Moving objects, too, are now possible for the first time, while the display also offers the option of linking objects to actions. It couldn't be easier for design engineers needing to create keys, dials and other control elements and assign specific functions to them. In addition to the screen diagonals of 5 inches, a 10.1-inch diagonal is also now available.
Screen with object graphics opens up a wealth of new options
With the use of style sheets, it is also possible to standardize the look of these elements, thereby creating elegant and user-friendly designs. Thanks to Unicode, all fonts of the world can be represented, guaranteeing global application. uniSKETCH, a specially designed PC graphic tool, enables users to create screen layouts and interfaces, edit the properties of objects and adapt style sheets. Tones can also be incorporated for a range of functions from acoustic feedback for operating procedures to entire jingles.
Also available as an option are display modules with a touch panel that use resistive or PCAP technology. With the PCAP Touch, multi-touch inputs familiar from smartphones and tablet computers can also be provided. The appropriate touch controller and software are already integrated into the display modules.
Where they are to be connected to external devices, actuators and sensors, the display modules are able to access all interfaces that are significant for industrial electronics – such as SPI, RS-232, I2C-Bus and USB. Several analog inputs, one PWM output and 16 digital I/O channels allow the module to be integrated into all types of control tasks. Moreover, the video input also provides for the direct playback of video signals. Also new is the internal macro language, which enables the displays to be operated as stand-alones for the simultaneous control of other devices.
First study, then try out
The company explains the new features of the uniTFT display by Augmented Reality (AR) app. Available for iPhone and Android systems, the free app provides an unprecedented means of displaying in-depth information on what is probably the most innovative fitted control unit in the world. It is based on the print advert that is to appear as part of an advertising campaign across a large range of media for the uniTFT, but is also available for downloading on the website. Point the camera of a smartphone or tablet at the ELECTRONIC ASSEMBLY advert and the module comes alive, and at the same time a short humorous film is launched on the display! The app also provides valuable information on this new screen with the aid of a 3D model. Why not try it out?
Thanks to their high contrast and extraordinarily wide viewing angle, OLED displays offer outstanding readability. In its EA OLEDL128-6 product family, ELECTRONIC ASSEMBLY now has a display module in its portfolio that boasts all these advantages. But there's even more to it than that: it has a life of over 50,000 hours of operation. Another unique selling point is the very rapid response time of this display, which loses nothing of its snap even at arctic temperatures as low as -40°C.
The display modules of the OLEDL128-6 family are available in three versions. The entry version has the type designation OLED128-6LGA. The OLED128-6GGA version of the display is fitted with an additional front screen to protect against scratching and UV rays and to establish a defined distance from the front of the device; the OLED128-6NGA comes without a polarizer but does have a silver background, making it ideal for installation behind a tinted glass screen. This version also meets higher aesthetic standards for devices intended for use in the home, for instance. The accessories available for all versions include a touch panel that can be used to realize modern, interactive device control systems.
Data exchange with the control electronics is optionally via an SPI or I2C interface. The modules are fitted with connecting pins in a 2.54 mm (0.1”) grid, making them suitable both for initial prototypes built on the breadboard and for series production because soldering into a PCB obviates the need for any further assembly techniques or structures.
Despite the onward march of digital technology, analogue dials are still easiest to read. The new ELECTRONIC ASSEMBLY EA W128128-XRxx family of OLED displays are ideal for visualizing measurement & control data. The built-in SSD1327ZB graphic controller can also place other content on the screen, for example icons and symbols.
The displays have a diameter of 37 millimeters, making them the ideal virtual round instrument gages in industrial and process automation and in all applications where easy, intuitive readability is essential. The units are designed to operate over an enormous temperature range (-40°C to +80°C). They are built to withstand severe frost, tropical heat and harsh environments. They also have a remarkably fast response time. The 128 x 128 pixels switch state in a mere 10 microseconds even at temperatures well below zero.
The EA W128128-XRxx displays offer a choice of SPI, I2C or parallel 8-bit interface for connectivity to the controller and other control electronics. An optional ZIF connector (Zero Insertion Force) is also available for gentle insertion and removal in the host device.
The units can be supplied with yellow (W128128-XRLG), white (W128128-XLW) or blue display( W128128-XRLB). The lifespan is 20,000 hours for the white and blue versions and 50,000 hours for the yellow version. The displays are now available for purchase from the ELECTRONIC ASSEMBLY webshop.
