Abstract:
1. A dual mode function pixel, comprising: a first membrane on which a self-luminescent element is formed; one or more membranes formed to surround the first membrane; and a lower layer formed below the first membrane and the one or more membranes to be spaced apart from the first membrane and the one or more membranes, wherein the dual mode function pixel is controlled such that the self-luminescent element is driven either to emit light in a first mode operation or to selectively reflect a projected light by utilizing an interference of light generated between the first to one or more membranes and the lower layer in a second mode operation, wherein the self-luminescent element is arranged with a reflective element in a vertical stack-up manner, wherein the lower layer makes the light emitted by the self-luminescent element be guided so that all of the generated light is emitted in an upper part of the pixel without being leaked into the lower part of the pixel, and wherein a wavelength of reflected light is changed according to a distance between the first membrane and the lower layer in the second mode operation; wherein the lower layer is formed with an electrochromic element that electrochromically interrupts emission of the projected light.
