The reduction of a structural pattern at specific gray levels or at the special condition of image data has mainly been discussed in digital halftone methods. This problem is more severe in some flat panel displays because their black levels typically are brighter than other displays blocks. The authors proposed an advanced confined error diffusion (ACED) algorithm which was a well-organized ha...

In this paper, we introduce a transparent fingerprint sensing system using a thin film transistor (TFT) sensor panel, based on a self-capacitive sensing scheme. An armorphousindium gallium zinc oxide (a-IGZO) TFT sensor array and associated custom Read-Out IC (ROIC) are implemented for the system. The sensor panel has a 200 × 200 pixel array and each pixel size is as small as 50 μm × 50 μm. The...

A new solid phase liquid crystal microlens array has been applied to Polarisation Activated Microlens flat panel displays that can be electrically reconfigured between a full performance 2D mode and a low cross talk autostereoscopic 3D mode. The solid phase microlens array enables significant reductions in device thickness and improved ruggedness compared to nematic phase liquid crystalline mic...

Two layer displays are constructed by overlaying one transparent flat panel on another, with a discernible physical separation between layers. This layout could increase the available pixels without increasing the width and height of the display. However, it is unclear if the second physical layer provides any advantage over simple alpha-blended transparency on a single layer display. We invest...

In this paper we investigate the impact of colorimetric observer categories on the prediction of the average suprathreshold color difference perception. The observer categories were obtained from an observer classification experiment, while the color difference data were obtained from an experiment involving a liquid crystal display (LCD) with fluorescent backlight. The same observer panel with...

1Advanced Computing Research Centre, University of South Australia, Mawson Lakes, South Australia 5095 {Phillip Lock. [email protected]} Abstract. Game playing in immersive projection environments such as caves and domes is assumed to offer an enhanced experience but there is little quantitative research that measures this. This paper reports on a study of user performance statistics wh...
