Replacement for Standard LCDs

Many circuits published in Elektor Electronics use LC displays. These displays are usually only intended to show text. Such displays are much less expensive than LCDs that can display complex graphic images.The legibility of most LC displays is without question good with normal lighting and proper contrast adjustment. Unfortunately, it degrades with reduced ambient light. Some LCDs have a ‘backlight’, which is a light source located behind the actual screen. When a backlight is used, the entire screen lights up, except where pixels are to be made visible. These locations are dark.
