We designed a horizontal parallax only light field display system which satisfies the super multi-view (SMV) condition. The pseudoscopic problem is solved by pixel mapping algorithm. The VAC (Vergence-Accommodation conflict) problem is relieved because the reconstructed 3D objects are not located at the display screen, thus the eye can accommodate on the reconstructed 3D objects rather than on the display screen. This system has a FOV(field of view) of ~30 degree and has a good motion parallax. The CII(computational integral imaging) simulation and the experimental results confirmed our design. This system is very close to a commercial 4k mobile phone’s panel parameters, thus can be applied to it directly only with some minor adjusts.
II-VI family semiconductor nanocrystals have attracted most interests in nanometer science and technology recently. The
quantum dots have many applications in optoelectronic device such as LEDs for its superior properties resulting from the
three-dimensional confinement effect of its carrier. Hybrid inorganic/organic electroluminescent devices were
demonstrated using monolayers of CdSe/ZnS core/shell QDs sandviched between two organic thin films. However, the
luminous efficiency of the hybrid in organic/organic device was very low. In this paper, an intermediate shell of CdS was
used as the lattice parameter adaptation layer to improve the core/shell interface quality the luminous efficiency of the
core/shell QDs. White light-emitting diodes (WLEDs) were fabricated by combining blue InGaN chips with luminescent
colloidal core/shell CdSe/CdS/ZnS quantum dots (QDs). Photoluminescence of CdSe/CdS/ZnS quantum dots
demonstrated high photoluminescence efficiency with a quantum yield more than 44%, and size-tunable emission
wavelengths from 380 to 620nm. WLED was successfully assembled by blue InGaN chip plus green and red emitting
CdSe/CdS/ZnS QDs. The InGaN chip white-light-emitting diodes with CdSe/CdS/ZnS quantum dots as the emitting
layer are potentially useful in illumination and display applications.
