Category Introduction
Products within this family are used for visual communication of text oriented information. Based on a variety of display technologies including liquid crystal, e-ink, and organic LEDs, they are distinguished from other display technologies by being conceptually divided into an array of addressable regions, each of which is capable of representing a single symbol, character, or digit. Though ill-suited for displaying images, video, or similar graphical information, their relative simplicity offers advantages in cost, design complexity, durability, etc. in circumstances where such capability is not required. Note that devices which use conventional LEDs to form luminous character segments are specifically excluded and grouped separately.
