A white light-emitting device (WOLED) was fabricated with a solution-processed single emission layer composing a small molecular mixed-host (MH) of N,N′-bis(naphthalene-1-yl)-N,N′-bis(phenyl)-benzidine (NPB) and 4,4′-bis(2,2-diphenylvinyl)-1,1′-bibenyl (DPVBi) by codoping blue dye of 4,4′-bis[2-(4-(N,N-diphenylamino)phenyl)vinyl]biphenyl (DPAVBi) and red dye of 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9,enyl)-4H-pyran...
We studied the degradation and recovery of gallium indium zinc oxide (GIZO) thin-film transistors (TFTs) with etch-back (EB) structures during the fabrication process. EB GIZO TFTs were degraded by a source/drain dry etch process that formed a conductive surface layer. Their switching performance was recovered using an O 2 ashing process that oxidized the conductive surface layer. In addition,...
Chromatic-stable white organic light-emitting devices (WOLEDs) are reported by combining simple blue fluorescent devices based on a new kind of blue emitter TC-1759 (derivation of N 6 ,N 6 ,N 12 ,N 12 -tetrap-tolylchrysene-6,12-diamine) with red color conversion layer (DCJTB). By adjusting the thickness of color conversion layers (CCLs), a very pure white light emission...
Eighty-seven participants read an e-book either from a near-to-eye display, a small-size display or a hard copy. Eyestrain, visually induced motion sickness, changes in visual functioning, user experience, and the essential optical parameters of the reading equipment were evaluated. The results indicate that reading from a hard copy was the most comfortable experience. All near-to-eye displays induced...
The effects of various sustain waveforms, such as non-overlapped, half-overlapped, and overlapped sustain waveforms, on the recovery characteristics of temporal bright image sticking in ac-PDPs were examined. The overlapped sustain waveform was found to be the most effective for a fast recovery from temporal bright image sticking based on intensifying the sustain discharge intensity without increasing...
Phosphorescent white organic light-emitting devices (PhWOLEDs) were fabricated by doping with the blue and yellow phosphors of iridium (III) bis (4,6-(di-fluorophenyl)-pyridinato-N, C2′) picolinate and [2-(4-tertbutylphenyl) benzothiazolato-N, C2′] iridium (acetylacetonate), respectively. The influence of interlayer on the performance of PhWOLEDs was studied with the assistance of three different...
Besides usability, visual aesthetics also strongly influence whether users will continue to trust and use a website. This study examined blogs to determine whether a correlation exists between the gender and visual preferences of young people toward blog interfaces. Few research on gender differences in visual preferences for blog interfaces have been published. Therefore the goal of this research...
How do consumers identify differences among product packages on the shelves of a hypermarket? This issue deserves our investigation. The current study aims to discover the factors in distinguishing bottle packaging and the formula for displayability (ability to display). The research process is divided into two stages. Stage One covers the “grounded concept of package design differentiation,” whereas...
In 3D technology, when the image isolation between the left image and right image is incomplete, each eye can see not only wanted image but also unwanted image as well. And for some types of 3D technology, this leakage of the unwanted image is not spatially uniform. In making this leakage less noticeable by the modification of the 3D image data, one value of the modification condition can make the...
