A black segment LCD is a type of Liquid Crystal Display that uses segments to display
numbers, icons, or graphical elements against a typically light or
colored background.
The black segments appear because liquid crystals block light in the activated
regions, creating sharp and clear contrasts for excellent
readability.
How Black Segment LCDs Work?
- Passive Matrix Design:
- Utilizes a grid of electrodes to activate specific segments by
applying voltage, creating a black appearance.
- Polarizers and Liquid Crystals:
- Polarizers and aligned liquid crystals block light in activated
regions, producing black segments.

4.5V 9PIN VA LCD Display, a long strip-shaped LCD display adopting
VA technology, with a working voltage of 4.5V and 9 pins. Such
products usually have the following characteristics:
Display technology: Using VA (Vertical Alignment) vertical
alignment technology, the display contrast is high on a black
background, presenting clear white graphics with good visual
effects.
Pin count: The 9PIN (9 pins) design enables it to connect with
external circuits, facilitating data transmission and the reception
of control signals. Different pins correspond to functions such as
power supply, ground, data transmission, and control signals.
Working voltage: The 4.5V working voltage is relatively low and has
certain energy-saving features, suitable for devices with low power
consumption requirements, such as small instruments and portable
electronic devices.
Appearance features: The long strip-shaped appearance makes it
suitable for situations with limited space and requiring a long
strip-shaped display area, such as strip-type instrument panels,
certain specific industrial control panels, etc.
