Segment LCD displays are a type of liquid crystal display (LCD) that uses individual segments to form characters or simple symbols. Unlike character LCDs that display pre-defined characters, segment LCDs offer greater flexibility in displaying custom symbols and icons. They are commonly used in applications where space is limited and simple, clear information is required. These displays typically consist of a liquid crystal material sandwiched between two polarized glass substrates with electrodes patterned to form segments. Applying a voltage to specific segments allows selective control over the transmission of light, creating the desired display. The design allows for customization and the creation of unique symbols tailored to specific needs.
These segment LCDs display alphanumeric characters and basic symbols. They are a cost-effective solution for applications requiring simple text or numerical displays.
Offering maximum flexibility, custom symbol segment LCDs can display virtually any symbol or icon, making them ideal for specialized applications. Manufacturers like Dalian Eastern Display Co., Ltd. offer extensive customization options for these displays, enabling precise control over segment shape and layout.
The most common type, seven-segment displays use seven segments to represent numerals 0-9 and some letters. They are widely used in digital clocks, meters, and other applications where numerical readings are essential. The simplicity and cost-effectiveness of seven-segment segment LCDs make them a popular choice.
