This thesis, we use high-transparent cathode and high-transparent backplane technology for 17-inch transparent AMOLED display. By touch the display and show the virtual information of background physical object on display, the augmented reality applications can be achieved in the future smart life.

 

In this study, the coplanar inner floating ring hole-patterned electrode liquid crystal lens array (CIFR-HPELCLA) was investigated to improve and achieve requirements in the integral imaging system.

 

A liquid crystal (LC) lens with a structure of two liquid crystal layers (TLCL)was investigated for augmented reality applications. The TLCL lens was capable of electrically tunable coaxial bifocals to achieve the characteristic of multi-imaging planes to be more suitable for augmented reality applications.

 

In this research, a green fluorescent dye, Alq3, were applied as a sensitizer with MADN as emitter to construct an organic light emitting diode (OLED) with TTAUC mechanism. By using a TDSB layer for TTAUC-OLED, the device efficiency can be enhanced due to higher triplet exciton contribution.

 

High-efficiency deep-blue fluorescence organic light-emitting diode was demonstrated with external quantum efficiency of 5.2% and CIE coordinates of (0.14, 0.08) by using a non-doped emttier exhibiting low photoluminescence quantum yield of 26.6%.

 

In this study, we demonstrated an organic light-emitting diode with charge recombination on green fluorophore and emission from red phosphor and blue triplet-triplet annihilation emitter by down- and up-conversion processes, respectively, for utilizing singlet and triplet exciton.

 

In this paper, we use the recognition threshold of human factors experiments to verify the satisfaction of displayed information which is higher than 70%. And we integrate the recognition threshold into test platform to improve the displayed quality of transparent display.

 

In this paper, we find the curve of the reading speed and luminance contrast ratio, and define the luminance contrast ratio under the specific slope as the critical contrast value of each condition. The critical contrast values for various conditions is between the range of 1.084 and 1.978.

 

Phenylpropyl or longer analogous substitutions were adopted to decorate the tetraphenylethene moiety for the construction of aggregation-induced luminescence compounds. The peak efficiencies of sky blue-emitting devices with a non-doped emitting layer could up to 3.5%, demonstrating the effective design concepts of a tetraphenylethene moiety decorated with phenylpropyl-based substitutions.

 

Twenty reflectance spectra of human skins were measured. Their principal component spectra were calculated. The reflectance spectra can be synthesized well with first two principal component spectra. The use of first three principal component spectra is preferred considering the shift of color coordinate from measured values.

 

This paper proposed a method of resolution enhancement by an optical simulation software for light field display. The method can provide accurate resolution simulation on the retina of the human eye. Following the simulation results to design a light field system, the resolution of displaying image can be improved.

 

Abstract: This study reports the asymmetrical diffraction using dye-doped twisted nematic liquid crystals (Dd-TNLCs). The photoalignment property of azo dyes and the polarization selective light absorption of dichroic dyes are used to achieve the asymmetrical diffraction property.
Key Word-- twisted nematic liquid crystal, gratings, asymmetrical optics.


 

Prolonged television watching might damage eyes and harm our health at night. The damage can be minimized by adjusting the watching distance and screen color. Melatonin secretion suppression can be reduced by extending watching TV distance.

 

This experiment is developing a new flexible substrate process, using UV-curable fiber reinforced resin as the substrate of the organic light-emitting diode. The current goal is to make components for lighting, and the fiber part is made using dust-free paper. Part of the resin is a UV-curable adhesive.

 

A new derivative CbzBiz was synthesized and successfully employed as the host of an efficient blue phosphorescent organic light emitting device (BPOLED). To farther improve the device efficiency performance, three electron transporting materials DPPS, 3P-T2T and PO-T2T were chosen to be the electron transporting layer of BPOLED.

 

In this study, we have tuned the emission wavelength of an exciplex OLED from red to near infra-red by incorporating three different dopants,The doped exciplex OLED shows a maximum EQE of 12.52% for R1 dopants, 8.02% for R2 dopants, and 6.17% for R3 dopants.

 

Transparent display can overlap fruitful information onto the background images to improve the entertainments, security, and commercial retail. However, the current pixel design of backplane makes heavy interference effects caused unacceptable background quality for transparent display. Here mention a new approach based on optical design to improve the background quality.

 

The fishbone polymer stabilized vertical alignment (PSVA) mode has a dark area around the edge of the electrodes. We propose an improvement of the fishbone electrode. As a result, we reduce the problem of the dark area around the edge and increase the maximum transmittance by 6.3%.
