N
experia’s new PCMFxHDMI2BA-C is a
combined, highly efficient, common mode filter and ESD protection device with wide 10GHz differential bandwidth. It is suitable for the latest HDMI 2.1 standard up to 12G FRL, where eye-diagram tests were passed even with “worst cable
manager for high-speed protection and filtering) said: “HDMI 2.1 enables displays with higher resolution and better colours. However, this demands greater protection against interference, especially in compact wireless applications. The performance and miniature size of these 2 in 1 combination-devices makes them highly suitable for ‘tv stick’ type plug-in designs.” This highly integrated device
provides excellent common mode attenuation at HDMI fundamentals: -19.4dB @ 3GHz and -16dB @ 6GHz. ESD performance is also good with devices offering a
clamping voltage of 7.4V at 16A transmission line pulse (5V at 8A). TDR impedance dip is <10Ohms for 200ps rise time. The inductance of the coil-pair offers a further significant reduction of ESD peak voltages while having a low inductance for differential signals. Lastly, the parts can protect and filter one, two or three differential line pairs, while footprint- compatible ESD protection devices without filter are available as well. In addition to HDMI 2.1, the
combined common mode filter and ESD protection devices suit other high speed serial interfaces including HDMI 2.0, HDMI 1.4, MIPI, DisplayPort.

DOUBLE SIDED HIGH BRIGHT DISPLAYS
Dual sided window displays from Crystal Displays cdesigned for stores, banks, commercial buildings, and many other applications consist of an outside facing display with a brightness of up to 3000 cd/m² (700 cd/m² and 1,500 cd/m² also available) and an inward facing display with an excellent high contrast and brightness of minimum 400cd/m² (700 cd/m² also available). This difference in brightness between screens
ensures that both sides are viewable to their audience no matter what the ambient conditions or usage. Despite being a double- sided display, this solution is incredibly slim and lightweight with a depth beginning at 12mm making them thinner than most single sided screens, creating a very sleek looking design. The double-sided display means you can
TFT DISPLAYS FOR HARSH ENVIRONMENTS WITH PCAP OPTION
TFT displays in various sizes, designed specifically for operation in harsh environments and with a choice of operating modes are available from specialist Relec Electronics. The thin film transistor (TFT) displays manufactured by
Futurelabs range in size from 3.5” to 17” and are available with optional PCAP (projective capacitive) touchscreens. The TFT displays are available with extended operating temperatures ranging from -40 to 85°C. They also have IPS (in-plane switching) technology for wide viewing angles in a range of lighting conditions in indoor and outdoor applications.
The Futurelabs IPS TFT liquid crystal display (LCD) modules are available in 3.5”, 5.0”, 7.0”, 10”, 10.4”,
12.1”, 15.6” and 17” versions. There is also a 12.3” letterbox LVDS TFT LCD. All Futurelabs displays are available with Rocktouch Rugged line PCAP touch panels, for best performance,
noise and water resistance. They are also available with a range of input options, for example, glove touch, operation with water, and firmware tuning. Resolution ranges from 640 x 480 RGB pixels to 1280 x 800 RGB pixels, and brightness levels are from
400 cd/M2 to 1000 cd/M2, depending on the model. The displays can be customised with touchscreens, mounting frames, cover lenses, optical bonding, surface treatments and enhancement films.

make full use of the space that you have. New marketing opportunities can be advertised to passers-by on the front high bright screen as well as building brand loyalty once your customers are inside on the lower brightness indoor facing side. CDS panels are also blackening resistant
HiTni Panels. In direct sunlight most LCD panels will overheat and blackening on the panel will occur but because CDS is a displays specialist, their engineers ensure they only utilise unique ultra-high brightness panels with specific high temperature liquid crystals that can withstand surface temperatures up to 110˚C. Consequently, no blackening defect occurs. With a built-in HD Android media player you
can update them using a USB memory stick i.e. simply load your pictures and videos onto a USB memory stick which will copy the files into its internal flash memory. Once you remove the memory stick the
screen will then start playing the pictures and videos in a continuous loop. Or for a small charge you can update your screens remotely via LAN, Wi-Fi or 4G.

NEW PIC24F MCUS FEATURE LOW POWER ANIMATED DISPLAY DRIVER FOR BATTERY-POWERED DEVICES
System developers of battery-powered and other power-conscious designs with and without LCD displays can now easily add an array of innovative features using a new line of PIC eXtreme Low Power (XLP) microcontrollers (MCUs) from Microchip Technology Inc. Packed with 14 types of Core Independent Peripherals (CIPs) that operate outside the Central Processing Unit (CPU) for power savings, the PIC24F GU and GL families of MCUs feature the CIP LCD with Autonomous Animation. Most display applications involve a few common animations like periodically
alternating between displays and blinking of pixels to indicate operation. By using the integrated LCD driver with autonomous animation, developers can offload most of these simple animation routines from the CPU, allowing animation even in doze, idle or sleep modes for optimal power savings. To assist in quickly designing such display interfaces, the new MCUs come with MPLAB Code Configurator (MCC) support. This graphical programming environment with LCD display designer helps eliminate the task of mapping the pins and segments.
