Abstract

An image displaying device includes a micro-LED-array having several LEDs, a controller electrically connected to the micro-LED-array for driving the LEDs such that they emit light, and a lens-array having several lenses. Each lens is assigned to one of the LEDs. Each lens is arranged in the light path of the light emitted by the corresponding LED such that the light emitted by the LEDs passes through the corresponding lens and is projected onto a screen. The lens-array is configured such that, when seen from the screen, a virtual image of the micro-LED-array is formed behind the micro-LED-array. The lens-array is a meta-lens-array and the lenses are meta-lenses.
