“…Kubo et al (2000) indicated that the TFT-LCD has been developed to excellent quality levels. Many researches indicated that the TFT-LCD has better visual performance than cathode ray tube (CRT) (Menozzi et al, 2000;Nose et al, 2000;Shieh and Lin, 2000;Wright et al, 1999).…”

“…Therefore, ambient illumination is an important consideration in workplace design with video display terminals. Although the surface of a TFT-LCD screen has an antiglare polarizer (Choi & Miyasaka, 1993), it still reflects the ambient lighting (Kubo, Uchi, Narutaki, Shinomiya, & Ishii, 2000). Pawlak (1986) proposed that the reflection property of a screen could be expressed as a reflection factor (q).…”

An empirical study was carried out to examine the effects of color combination and ambient illumination on visual perception time using TFT-LCD. The effect of color combination was broken down into two subfactors, luminance contrast ratio and chromaticity contrast. Analysis indicated that the luminance contrast ratio and ambient illumination had significant, though small effects on visual perception. Visual perception time was better at high luminance contrast ratio than at low luminance contrast ratio. Visual perception time under normal ambient illumination was better than at other ambient illumination levels, although the stimulus color had a confounding effect on visual perception time. In general, visual perception time was better for the primary colors than the middle-point colors. Based on the results, normal ambient illumination level and high luminance contrast ratio seemed to be the optimal choice for design of workplace with video display terminals TFT-LCD.

“…Oyster (1999) reported that blink efficiency was dependent upon many factors: emotional state, mental effort, illumination level and atmospheric condition, etc. Kubo et al (2000) opined that the increase in the level of illumination resulted in more visual fatigue to the subject. Lin and Huang (2006) showed that there was no effect of ambient illumination on the character identification task for different contrast ratios.…”

This study investigated the effect of varying levels of illumination, noise and colour combination on blink rate for subjects of different age groups (21-30, 31-40 and 41-50 years) having Internet exposure duration of less than 2 h/day (category 1) and more than 2 h/day (category 2). The pseudo reading task was designed as a software program to investigate the reading task performance. Results showed that the text-background colour combination was significant on the change in spontaneous eye blink rate (SEBR) values on both categories of users for age groups of 21-30 and 41-50 years. The effects of illumination and noise were not significant for subjects of all categories and age levels except for age group of 31-40 years with Internet exposure duration of more than 2 h/day, where illumination was observed to be significant. The results of the study further showed that ambient illumination did not affect significantly the SEBR values for every age group investigated in this research.
