This family of products is used for displaying text-based information in a visual format. These products utilize a range of display technologies, including liquid crystal, e-ink, and organic LEDs. They are distinct from other types of displays as they are conceptually divided into an array of addressable regions, each capable of representing a single symbol, character, or digit. While they may not be ideal for displaying images, video, or other graphical information, their simplicity offers advantages in terms of cost, design complexity, and durability, especially in situations where such capabilities are not necessary.
It is important to note that devices which use conventional LED technology to form luminous character segments are specifically excluded from this category and are grouped separately. This highlights the unique characteristics of the products within this family, which are designed primarily for the display of text-based information.
Liquid crystal displays are commonly used in a wide range of applications, from calculators and digital watches to computer monitors and televisions. E-ink displays are often used in e-readers and electronic paper products, while organic LEDs are utilized in smartphones, tablets, and other portable devices.
The addressable regions in these displays can vary in size, depending on the intended use of the product. For example, a smaller display may have a limited number of characters or symbols, while a larger display may be capable of showing more extensive amounts of text-based information.
In summary, products within this category are used for visually displaying text-based information, utilizing various display technologies, including liquid crystal, e-ink, and organic LEDs. They are conceptually divided into an array of addressable regions, each capable of representing a single symbol, character, or digit. These products offer advantages in terms of cost, design complexity, and durability, especially in situations where the display of images or videos is not required.
