Cables. We expect, like us, you have a love/hate relationship with them. On the one hand, for most applications when a TFT is connected to a touch, the complete Stack is connected over a short cable to a board. And that works just fine. After all, for this kind of application, a wireless PCAP makes no sense.
Capacitive sensors are great – highly reliable and have a wide range of functions. But in the medical world there are some very particular requirements around the service life of such sensitive sensor technologies.
We are frequently asked if we can replace old membrane keypads with a new PCAP design. It makes sense, as the membrane design can present many problems – particularly as it ages. Simply put, membrane keys are less durable and their PET foil, which controls responsiveness, can and will break with frequent use.
Plenty of displays need to be able to cope with the varying demands of outdoor use – think EV chargers, construction sites, agricultural vehicles, boats and many more. Displays in these highly variable locations are not only exposed to the elements but feel the full force of heavy duty use every day. As a result, Innolux has launched a new line of high brightness TFT displays that are more than up to the challenge.
Thin, light, cost effective, but with industrial grade reliability and performance, AUO Display+ 15.6” integrated touch solutions are perfect for a range of indoor uses – in-flight entertainment, home automation panels, Point of Sale and kiosk applications.
Industrial standard displays need to perform under all circumstances – in extremes of weather and temperature, or environments where there is a high risk of damage. Traditionally, this has been fulfilled by resistive touch displays, which are essentially two transparent film layers, each with a conductive layer on the inside. To operate, these layers press against each other. However, this continual pressure can be problematic, as it means they lose their resistance over time and eventually wear out. Scratching and a lack of optical clarity is also an issue.
We have seen a huge surge in the use of IoT devices in the last decade or so across various industries. More companies are focused on developing devices that will become part of the connected ecosystem. According to Markets&Markets, the IoT market size is expected to grow from USD 300.3 billion in 2021 to 650.5 billion by 2026. However, with this massive growth comes various challenges and concerns, and one of the biggest challenges has been the power consumption.
As a leading provider of industrial visualization systems, Avnet Displays is implementing complete PCAP glass touch solutions using a new technology to achieve bigger sizes, better optical and EMI performance, along with lower sheet resistance.
Colour TFT (Thin Film Transistor) displays are everywhere. From our beloved phones and wearables to billboards, dashboards, medical equipment and even coffee machines. TFTs are essential to the clear and high-resolution view you expect of any digital display. But as these examples show, the places and spaces in which you might find one vary greatly, and each respective application will have a slightly different operational requirement from its TFT.
Touch-responsive surfaces are as ubiquitous as they are taken for granted but, for us, their sensors are the immediate power behind an effective display solution. We work with companies all over the world, supplying sensors and custom integrating them into display solutions for some of the most challenging industries you can imagine (and some you probably can’t!). So, we wanted to take some time talk about the two main types of touch sensors we offer.
