Available in many different sizes like 9.14mm,14.20mm,20.40mm,38.10mm,57.0mm and 100mm (Commonly used/available size is 14.20mm).Available in two modes Common Cathode (CC) and Common Anode (CA).This design information is valuable especially when designing medical equipment for critical care and operating room environments.Controls the left bottom LED of the 7-segment displayĬontrols the bottom most LED of the 7-segment displayĬonnected to Ground/Vcc based on type of displayĬontrols the right bottom LED of the 7-segment displayĬontrols the decimal point LED of the 7-segment displayĬontrols the top right LED of the 7-segment displayĬontrols the top most LED of the 7-segment displayĬontrols the top left LED of the 7-segment displayĬontrols the middle LED of the 7-segment display 188 inch LED display (VAS of 0.179 to 0.0573 degrees) The font proposed by Van Nes and Bouma was found to reduce errors by almost 50 percent at all but the longest viewing distance. The error rate and response times for five reading distances from 8 to 25 feet were evaluated for a. Subjects performed a digit cancelling task as single digits were presented on the seven segment display at various reading distances. An alternative font as proposed by Van Nes and Bouma (1980) was compared to the font used currently by many commercial products. This design information is valuable especially when designing medical equipment for critical care and operating room environments.ĪB - The legibility of seven segment numeric displays was investigated for two different numeric LED fonts at five reading distances. N2 - The legibility of seven segment numeric displays was investigated for two different numeric LED fonts at five reading distances. Comparisons of two fonts at various distances T1 - Legibility of seven segment numeric led displays.
