Core Features
Display Principle and Structure
7-segment display module: Composed of 7 independent liquid crystal segments (labeled a-g), some of which also include the eighth segment as a decimal point. By controlling the combination of the segments' illumination, it can form numbers from 0 to 9 and simple letters such as E, F, and C. The structure is simple and the driving logic is clear.
Customized dot matrix LCD screen: Based on the pixel dot matrix, the dot matrix size and layout can be customized according to requirements. Icons, symbols, and even company logos can be added. Some dot matrix segments can be burned onto glass for permanent display, and they can be visible without power supply.
The overall structure adopts a two-layer structure of indium tin oxide (ITO) glass sandwiching the liquid crystal, divided into transparent type, reflective type, and semi-transparent type. The transparent type requires a backlight, the reflective type relies on external light for display, and the semi-transparent type combines both characteristics.
