摘要

Two experiments were performed by 8 subjects to test discriminative ability of icons and Chinese characters on three kinds of different displays-CRT, LCD and PDP. The showing time of an icon or a character on a display unit has to last long enough so that people can recognize it. The minimum time required is defined as "recognition time threshold" (RTT). This value can be used as an index of visual performance. To compare different type of displays, two experiments were carried out to measure their RTT. These results indicate that LCD is better than CRT in whole shape discrimination and CRT is better than LCD in detail discrimination.
