Nowadays most embedded designs on the market, from consumer white goods to industrial machinery, incorporate some form of display. The current sophistication of touch displays, enabling commands to be given through swipes and gestures, owes much to the early smartphone designers. Touch-enabled LCD displays can reduce system cost by removing the need for switches and push buttons. Product reliability can also be improved by using capacitive touch screens to avoid dust and moisture ingress through switch enclosures. Additionally, a well-presented, visually pleasing and intuitive display contributes significantly to the aesthetics of a product, strengthening product brand value and user confidence.
