It is for this reason that slate tablets are designed to be held in one hand while the other interacts with the device. Organisations such as Sharp are constantly innovating monitor technologies. It was the first business to successfully manufacture and mass produce ‘IGZO’ ultra-high-definition signage solutions. The monitors utilise artificial transparent crystalline oxide semiconductors, composed of idium, gallium, zinc, and oxygen for a more energy efficient and well-lit 4k display. Today’s monitors are moving away from liquid-crystal display technology, which uses cold cathode fluorescent lamps for backlighting.
