由于在袖珍计算器中的广泛使用,发光二极管显示器已为我们生活中所常见。这类显示器通常用八个七段式的数字,约六十个数据点。发光二极管显示器在技术上和商业上虽然受到重视,但是目前尚不具备作更大更多字母的显示器的条件。这主要是因为下边两个原因。首先,半导体材料本身的成本占整个器件成本很大比重,使用面积愈大,成本愈高,其次,要增加数据点,就须增多连线而提高了装配成本,或者是减少占空因数,以保证更大程度的多路传输。这后一种办法有局限性,因为对于L单位的总亮度,瞬时亮度必须是nL,n为每一循环中多路
Due to the widespread use of pocket calculators, LED displays have become commonplace in our lives. Such displays usually use eight seven-segment numbers, about sixty data points. LED display technology and commercial attention, though, but do not have the conditions for larger and more letters of the monitor. This is mainly because of two reasons below. First of all, the cost of the semiconductor material itself accounted for a large proportion of the cost of the entire device, the larger the area used, the higher the cost, and secondly, to increase data points, we must increase the connection and increase the assembly costs, or reduce the duty cycle to To ensure a greater degree of multiplexing. This latter approach has its limitations because, for the total brightness of L units, the instantaneous brightness must be nL, where n is the number of multiplexed
