Relec and Digiwise team up to aid display design
The popularity and versatility of HDMI means that embedded SBCs face more display design demands. To stay ahead of this industry trend Relec Electronics and its partner Digiwise have been developing new sizes and products to meet customers’ innovative design requirements.
Medium to large TFT displays are increasingly popular because the thin form factor can be embedded into systems which are often subject to varying lighting conditions which can make conventional displays difficult to read. They are typically used in industrial automation, automotive, defence and marine systems, medical equipment, rail applications, broadcast and signage.
Today, most embedded single board computers (SBCs) have a direct high-definition multimedia interface (HDMI) as the standard video output, but as the use of video content increases, the demands of developers have broadened.
A HDMI interface on a display significantly reduces design time and associated costs to accelerate time to market.
Accurate timing and EDID (Extended Display Identification Data), which ensure that the display and SBC communicate in sync, can be developed on a bespoke PCB by Relec.
Another benefit of an integrated HDMI is that it eliminates complex cables as a single, simple HDMI connector can be used.
Relec Electronics offers a comprehensive range of TFT display sizes: 4.3-inch, 5-inch, 7-inch, 8-inch, 10.1-inch, 11.6-inch, 15.6-inch and 21.5-inch.
They all benefit from the latest in-plane switching (IPS) technology which offers superior colour quality and a wide range of viewing angles. The TFT displays can also be mounted portrait or landscape orientation to meet a wide variety of space constraints, locations and applications.
The TFT displays available from Relec Electronics also include an integrated backlight system for improved visibility, 16.7M colours, high contrast ratios and brightness levels from 600 cd/m² to 1500 cd/m². Resolution is from 800x480 to full high-definition (FHD) 1920x1080.
In addition, the displays operate from a single 12 Vdc input and operate over a wide temperature range (-30°C to +80°C).
In addition to standard products, Relec’s team of design engineers can work with a customer to find the best display solution for a particular project, environment and application.
For example, Relec can provide a fully integrated touch panel which can be projected capacitive (PCAP) or resistive technology.
It also offers optical bonding, for a ruggedised display that offers improved durability and ruggedness as well as increased readability in sunlight conditions.
Other screen enhancements available include anti-glare solutions for high-ambient environments, reduced reflections (via optical bonding) and ruggedised panels with either thicker glass panels or optical bonding.
Custom features include a custom cover lens with a choice of glass or PMMA, custom shapes and sizes, custom mounting frames, including round shapes, graphic printing (one or more colours), apertures in the glass to accommodate USB sockets or mechanical switches, for example.
