Transparent displays enabled by resonant nanoparticle scattering

Abstract

The ability to display graphics and texts on a transparent screen can enable many useful applications. Here we create a transparent display by projecting monochromatic images onto a transparent medium embedded with nanoparticles that selectively scatter light at the projected wavelength. We describe the optimal design of such nanoparticles, and experimentally demonstrate this concept with a blue-color transparent display made of silver nanoparticles in a polymer matrix. This approach has attractive features including simplicity, wide viewing angle, scalability to large sizes and low cost.

Impact of titanium dioxide nanoparticles on purification and contamination of nematic liquid crystals

“…The development of display techniques has led to the construction of high-quality screens including fully transparent [1], flexible screens [2] and dual-view [3] displays in the past years. The area of LCs for non-display applications is also rapidly growing.…”

Direct imaging of isofrequency contours in photonic structures

“…In particular, transparent displays have been realized using plasmonic resonances ( 50 , 51 ), but the high-quality factors of photonic resonances, due to negligible absorption and narrow linewidths, may allow for significantly better performance. If the isofrequency contour is engineered to be at large angles and therefore far away from a viewing audience, the resonance-enhanced scattering process can be used for a transparent display.…”

Image quality affected by diffraction of aperture structure arrangement in transparent active-matrix organic light-emitting diode displays

“…Project technology, liquid crystal displays (LCD), electrowetting displays (EWD), projectors, organic light emitting diodes (OLED), and other technologies are typically adopted to create transparent displays [9][10][11][12][13][14][15][16]. In project technology, information is projected onto a transflective screen, and the user can combine this display information with the real image behind the screen.…”
