Subpixel rendering (SPR) technology is a method for improving visual resolution includes sub-pixel arrangement and rendering algorithm. In this paper, we present a novel rendering algorithm to improve image sharpness. The algorithm dynamically references the adjacent image data including saturation (S) and luminance (V). Then the sequence for rendering the image data is calculated by S, V and pre-determined weighting factors P. Meanwhile, the weighting factors for most sub-pixel arrangements are optimized by minimizing the root mean square error (RMSE) from the original image data. The algorithm is finally exemplified on a 8" 424 ppi LCD display. It shows that the proposed method reduces both the color fringing artifact and blurring in sub-pixelrendered images and keeps the same resolution perception in comparison with conventional RGB stripe.

Objective and subjective indicators and methods for comparing the effects of three-dimensional display technologies on viewer discomfort, fatigue, and satisfaction based on human factors were proposed. Based on 7 indicators (including VA, diopter, pupil size, IOP, HFC, CSV and CFF) and the ergonomic evaluation, the conclusion that PR and deadzone-free AS displays are better than SG displays could be drawn. In the meantime, a relationship between the visual discomfort/fatigue indicators and causes of physiological feedbacks was inferred from analyzing the experimental data and consulting with the ophthalmologist.

In this paper, we propose a novel analytical method for moire phenomenon in autostereoscopic displays. First, the simulation model of 3D moire pattern has been developed. Secondly, compute the CSF (Contrast Sensitivity Function) for each spatial frequency of simulated moire. Finally, applying the threshold of human visual response to the analyzed results, the visibility of the moire pattern is able to be predicted in advance. With the proposed algorithm, it is more accurate and effective to design moire-free 3D display.

Generating OD look-up table (LUT) of LCD is a cumbersome and time-consuming process. We employ subjective experiment to obtaining optimum OD gray level. Based on the experiment results, a novel algorithm is proposed for generating optimum OD LUT. Combined with measurement system, OD LUT can be generated automatically and effectively.
