Readability of Characters on Display Faceplates in Terms of Human Sensation
Readability tests were carried out for three types of displays; a TFT-LCD with backlight of white LED matrices, a TFT-LCD with backlight of two-row cold cathode fluorescent lamps (CCFLs), and a CRT. Readability of the TFT-LCD with backlight of white LED matrices was highest among the others from the viewpoint of flicker and luminance unevenness. The efficiency of VDT operations contiguously carried out for up to 90 minutes for the TFT-LCD with backlight of white LED matrices was higher than the other two types of displays by a factor of 10 to 20 %, since the readability for up to 30 minutes was greatly improved by TFT-LCD with backlight of white LED matrices. Throughout these experimental studies, we found that the temperature rise was recognized of the cilliary muscles surrounding the eye lenses, when measured on the infra-red thermometer, due to fatigue of the cilliary muscles during the VDT operations.
