Sixteen younger and 16 older drivers participated in this simulated driving experiment. They were instructed to perform a push button task and a navigation task while using the displayed traffic information to drive through each scenario. The Advanced Traveler Information (ATI) was presented visually only, aurally only, or by multi-modality display. All drivers made significantly fewer errors in responding...
We present a concept for image quality that is based on a definition of quality in terms of the degree to which something satisfies the requirements imposed on it. An answer to the question what image quality is, must therefore necessarily include answers to the questions: what are images, what are images used for, and what are the requirements which the use of images imposes on them. In this paper,...
The full color, 5.8in. TFT-AFLCD panel was prepared. The surface dependence of electro-optical properties and aligned state of antiferroelectric liquid crystal has been studied. A low pretilt aligning polyimide was used as the aligning film. Two times rubbing method, the first rubbing at polyamic acid state and the second rubbing at polyimide, was applied to control the surface of polyimide. The surface...
Spatial charges, such as rare earth ions, impurities, vacancies and ionized lattice ions, exist generally in the phosphor layer of thin film electroluminescent displays (TFELD). The influence of these charges on the transport properties of TFELD is investigated for the first time in this article through phase shift analysis and Monte Carlo simulation. Scattering rates of spatial charges are calculated...
On the basis of signal theory, we analyse the different information content of colour stimuli that correspond to variations along the red-green and yellow-blue channels (or chromatic signals). The experimental results for stimuli generated by two CRT colour monitors and extended to handmade samples show a higher chromatic contrast when pairs of stimuli are generated by red-green variations than by...
The luminescence properties of Zn-rich zinc oxide thin film have been investigated. The luminescence of ZnO:Zn is attributed to the band to band radiative transition and the recombinations at self-activated centers intrinsic to ZnO. The UV and blue electroluminescence emission band centered around 480nm and the broad ultraviolet photoluminescence spectra are observed. The field-induced ionization...
