Displays & Interfaces SHE-compliant automotive 2.5D display controllers feature 300MHz ARM core Toshiba Electronics Europe has announced three new display processors for automotive instrument clusters with TFT LCD sizes ranging from 3 to 8 inches. The Capricorn-Bt0, Capricorn- Bt1 and Capricorn-C0 feature a highperformance ARM Cortex-R4 core running at 300MHz with on-board graphics engines and a built in graphics display controller. An integrated intelligent stepper motor controller allows each device to also drive needles on speedometers, rev counters and other conventional instrument gauges. All three devices can deliver 3D-style effects without the expense of a 3D GPU. The Capricorn-Bt0 IC supports a single display, while Capricorn-Bt1 and Capricorn- C0 have two independent display controllers for instrument clusters. The built-in ‘2.5D’ graphics accelerator supports key graphics functions such as warping, blitting, scaling, drawing and perspective transformation. The latter makes 3D effects including ‘Cover Flow’ and mirroring possible, realizing true perspective viewing. Hardware bitmap rotation with an angle resolution of just 0.1° precision combines with high-quality filtering and a patented stroboscope compensation technique to smoothly represent dials, rapidly rotating pointers and other animations. Toshiba has expanded the image handling capability of its latest Capricorn processors by supporting ‘on-the-fly’ decoding of high-compression PNG images. Implementing a multiple stream PNG decoder engine allows direct use of PNG images for graphics operations and direct display. The devices incorporate a variety of safety features including a display readback function, protection in accordance with AUTOSAR 4.0, and error correction. Each device also incorporates Toshiba’s security module supporting SHE (Secure Hardware Extension). Toshiba Electronics Europe www.toshiba-components.com Near-to-eye 2048x1536 pixels microdisplay offers immersive field of view The QXGA-R9 developed by Forth Dimension Displays is a high resolution (2048x1536 pixels) microdisplay based on reflective ferroelectric-liquid-crystal-on-silicon (FLCOS) technology. Designed to be configured as a near-to-eye display, the 21mm diagonal unit features 3.1 million pixels and its wide field of view of over 100° enables the implementation of truly immersive head mounted display systems, without noticing the pixels’ structure. Operating as a spatial light modulator, the unit reflects light from an RGB diode and modulates the reflected light spatially and sequentially to display binary bit-planes at frequencies over 5.7kHz. Using the company’s so-called Time Domain Imaging technology, it supports 120Hz native WUXGA performance at 24- bit colour (8-bit per colour), with a fully scalable brightness and a customizable colour gamut. By switching the FLCOS pixels to form sequential grey-scale images synchronized with sequential red, green and blue illuminations, Time Domain Imaging renders full colour images (the human eye integrates the three primary colour grey-scale images into one). Because there are no sub-pixels nor any RGB colour filters, the display boasts a high fill factor, greater than 94% according to the manufacturer. The unit comes with a USB interface for system control, a GUI for system set-up and administration, a default DisplayPort video input and a daughterboard expansion header for custom system integration. Forth Dimension Displays www.forthdd.com Multi-touch panels comply with the EMC standards for industrial applications The PCI multi-touch panels (Projected Capacitive Input Systems) offered by Schurter comply with the EMC standards for industrial applications. The front glass surfaces that cover the entire operating area on the front offer many design possibilities by rear printing and by selecting different surface structures and geometries. PCI panels allow the user to operate the system with more than just one finger at a time. Depending on the size and requirements, the touch sensors are designed differently for integration behind customized front glasses. Glass-based sensors are bonded in an automated, highly transparent UV bonding process, film sensors are laminated with a special lamination process in the autoclave with the cover glass. The bonding with a carrier plate or with a special housing enables a peripheral protection against mechanical stress on the edges and the panels are sealed according to the IP 67K protection class. These touch panels ensure accurate activation, are easy to clean, chemically resistant as well as scratch- and abrasion-resistant. The parameter adjustment of the touch controller prevents false activation caused by dirt or fluids and allows for operation with gloves. By selecting an anti-glare and chemically-strengthened glass, the PCI touch panels are particularly suitable for use in industrial automation, engineering and medical technology. Schurter www.schurter.com 19-inch colour TFT display with 1000:1 contrast ratio targets medical applications AU Optronics has released the G190EAN01.0, a 19-inch colour TFT display with 1000:1 contrast and wide viewing angles especially designed for the medical market. The display offers wide viewing angles so that the content can be read well out of all different views, more particularly so with monochrome contents where only little colour inversion can be noticed. Depending on the application in which the panel will be used, AUO offers TFTs in TN-technology (twisted nematic) as well as in MVA-technology (multi-domain vertical alignment). Every cell technology has got advantages as well as disadvantages relating to contrast ratio, viewing angle, temperature range, colour inversion and ultimately, pricing. The G190EAN01.0’s 0 to +50°C temperature range makes it suitable for use in many indoor, medical applications. For the future AUO is planning some more new products in 19” size. The company also plans to release a monochrome display with a brightness of 1000cd. Data Modul www.data-modul.com 28 Electronic Engineering Times Europe October 2013 www.electronics-eetimes.com
