Display brings excellent all-round readability over a wide viewing angle

A new and cost-effective 7” PCAP touchscreen display module that achieves excellent readability over a wide viewing angle even in high ambient light conditions has been launched by AndersDX. The display is based on moth-eye film, which the company can also supply on other displays. The moth eye film surface treatment applied to this 7” TFT display greatly uses technology which mimics the microsized lenses in the eye of a moth. It reduces internal reflections between the display and PCAP touchscreen, giving much better readability especially in outdoor applications where sunlight and other factors contribute to creating a difficult environment. The film gives an improved visual appearance when in use and ensures that the display looks completely black when off. Commenting, Paul Hooper, display group manager at AndersDX said, “More and more electronic displays are being used outdoors, to control instruments, to provide information and to deliver advertising. It is essential that these screens can be viewed clearly at all times of day, in any light condition. Moth-eye film is an affordable technology that greatly improves readability. We are amongst the first to offer this alternative to the industrial display market.” Moth-eye film uses nanostructures to reduce reflections and limit the effect that ambient light has on the display. They achieve very low levels of reflectivity over the entire visible spectrum, enabling the display to be read easily from wider angles. The 7” display module has a resolution of 800RGB*400 and a colour depth of 16M. It is a transmissive display, and includes a capacitive touch panel. Viewing angle is 50-degrees x 70-degrees x 70-degrees x 70-degrees typical. The moth eye film improves clarity across the full viewing cone compared to an untreated capacitive touch display module.
