Boosting user interface creativity

Anders is expanding manufacturers’ opportunities to create innovative user interfaces with a selection of circular TFT-LCD colour displays that integrate a rotary switch


Featuring display sizes of 1.3, 2.1 and 2.47in, Anders range of integrated displays/switches suits applications including heating systems, industrial controls, IoT devices, boilers, white goods, fitness equipment and audio products.


The rotary switch permits convenient and intuitive adjustments such as temperature, volume, motor speed, timer settings, dimming and ambience control. The switch is operated by turning a perimeter ring, which provides a tactile response to confirm the selection and hold the switch in position.


Circular displays represent an opportunity to grab users’ attention and create an almost infinite range of imaginative effects. Examples include: making a timer count up or down by illuminating or turning off graduations around the edge; darkening or brightening the display as the user adjusts a lighting dimmer; or changing the backlight colour of a heating or air-conditioning controller depending on the user’s setting.


Anders’ in house engineering team can support customers with choosing the display, user-interface design, software development and integrating features such as optical coating and touch sensing.


The 1.3in rotary display is available with SPI or UART interface, whereas the 2.1 and 2.47in feature MIPI and UART. Anders states each display leverages IPS TFT technology to ensure a wide viewing angle, excellent colour and a high contrast ratio. These circular displays are available as modules without the rotary housing and are available with a converter board for evaluation.


Further developments planned for this range include a radial graphics evaluation kit including a microcontroller board and software libraries. The kit will help manufacturers quickly develop a GUI on a circular display and includes code examples optimised for circular applications that simplify development.
