“…Zhu and Wu (1990) have shown that raising screen luminance from 20 to 40 cd m 72 improved the performance of a letter counting task at a 7:1 contrast level, but had negative effects at a contrast level of 9:1. In a letter identification task, Lin (2005) showed a similar interaction effect between screen luminance and luminance contrast ratio. However, the reasons for these effects were not given by the authors.…”

The effect of display polarity and luminance contrast on visual lobe (effective visual field) shape characteristics was studied using three levels of luminance contrast with combinations of positive and negative polarities. The binocular effective visual field for a detection task, with a peripherally presented target (V) embedded in a homogeneous competing background (Xs), was mapped on 24 imaginary axes passing through the fixation point. The results showed that visual lobes mapped using positive polarity were statistically larger in area, rounder and more regular in shape than those for negative polarity. The medium contrast condition lobes were more symmetric and regular than low contrast condition lobes, and lobe area and perimeter increased with increasing luminance contrast ratio. Under the interaction of positive polarity and high luminance contrast, visual lobes were found to be larger, smoother and rounder. The high level of luminance and contrast however resulted in a higher degree of visual discomfort. The results indicated that positive polarity and contrast of medium (26:1) to high (41:1) levels are possible display settings for better visual lobe characteristics and better anticipated search performance.Practitioner Summary: The effect of display polarity and luminance contrast on visual lobe shape characteristics was examined with uniform stimulus materials in this study. The results help to identify the optimum display settings for luminance contrast and display polarity to enhance lobe shape characteristics and hence search performance in industrial inspection tasks.

“…Therefore, under a given pixel voltage variation, the green sub-pixel deteriorates the luminance uniformity more severely than the other two color sub-pixels [16]. In both techniques 1 and 2, half of the green sub-pixels are charged before the adjacent sub-pixels and the rest of them are charged after the adjacent sub-pixels.…”

This paper proposes a new dot inversion data addressing technique to achieve a high image quality in thin film transistor liquid crystal displays (TFT-LCDs) using a double rate driving method. The proposed data addressing technique optimizes the charging sequence of sub-pixels to reduce the variation in pixel voltage caused by parasitic capacitance, while maintaining the low-power consumption of the data driver IC. To verify the performance of the proposed technique, three 17-inch full high definition fringe field switching mode TFT-LCD samples were fabricated and evaluated. The deviation of the green sub-pixel luminance using a test pattern (R0, G127, B255) is less than 2 gray levels, and the power consumption of the data driver IC when displaying a mosaic pattern is reduced to 3.6 W at a 13 V supply voltage. In addition, a new pixel structure with a high 59.4% aperture ratio reduces the power consumption of the backlight unit to 9.8 W, which is 16% less than a conventional design.Index Terms-Double rate driving (DRD), low-power consumption, image quality, data driver IC, TFT-LCD.

“…Color is a powerful component of screen design, because it attracts human attention (Noiwan and Norcio, 2006) and affects visual performance in text oriented searches (Post and Reinhart, 1997;Fukuzumi et al,1998;Liu et al,1999;Menozzi et al, 2000;Lin, 2003Lin, , 2005Wang et al, 2003;Shneiderman and Plaisant, 2004;Noiwan and Norcio, 2006). Although most product customization interfaces are heavily color-based, few studies have discussed the effects of screen layout on the product color selection process.…”
