Design service supports increased video output applications

Video output is increasingly used in medical equipment and CCTV surveillance systems, as well as automotive, defence, marine and broadcast applications. Relec Electronics has announced a display design service to integrate video output using medium to large TFT displays.

The service is intended to help developers fit a display into a thin form factor into systems which will be subjected to varying light conditions. Conventional displays can be difficult to read in these conditions which cannot be tolerated in transport or medical equipment, for example. In industrial automation and rail applications, the designer also has to consider the harsher operating conditions which will be encountered.

Relec Electronics and its partner Digiwise have been developing new sizes and products to meet innovative design. For example, an HDMI (High-Definition Multimedia Interface) significantly reduces design time and associated costs to accelerate time to market. Accurate timing and EDID (Extended Display Identification Data) ensure that the display and SBC (Single Board Computer) communicate in sync. This can be developed on a bespoke PCB by Relec.

An integrated HDMI also eliminates several complex cables using a single, simple HDMI connector. Relec offers a range of TFT display sizes: 4.3, 5.0, 7.0, 8.0, 10.1, 11.6, 15.6 and 21.5-inch and all models feature In-Plane Switching (IPS) technology for a range of viewing angles.

The TFT displays can be mounted in portrait or landscape orientation, even if they are integrated in applications which are restricted by location or with limited space.

TFT displays available from Relec 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 800×480 to full high-definition (FHD) 1920×1080. They operate from a single 12V dc input and operate over a wide temperature range (-30°C to +80°C).

The company’s team of design engineers can work with customers to develop a display where a standard product is not available. It can, for example, 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 is durable with 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.

Other custom features include a custom cover lens with a choice of glass or PMMA, custom shapes and sizes, custom mounting frames, graphic printing (one or more colours) and apertures in the glass to accommodate USB sockets or mechanical switches.
