Effects of contrast ratio and text color on visual performance with TFT-LCD

Abstract This study investigated the effects of contrast ratio and text color on visual performance for thin film transistor liquid crystal display screen characteristics. Results showed that contrast ratio significantly affected visual performance. Subjects performed better with the higher contrast ratio than with the lower contrast ratio. Text color did not significantly affect visual performance if an acceptable level of contrast ratio was present. Contrast ratio was more important than text color on visual performance. Relevance to industry The TFT-LCD is becoming the most popular VDT for computers today. Contrast ratio and text colors are factors that affect VDT performance. The application of the results from this study may improve VDT performance.
