Custom LCD Segment Display Module HT1621 TN Positive Blue Backlight For Charger

A Segment LCD Module is a type of liquid crystal display specifically designed to display fixed, predefined symbols, characters, or segments, such as digits or icons. It's one of the simplest and most energy-efficient display technologies, ideal for applications where only basic visual information is required.

Advantages

• Extremely energy-efficient.
• Simple and cost-effective.
• Robust for use in rugged environments.
• Can be customized for specific applications with tailored segments.

Limitations

• Limited to predefined patterns or symbols.
• Cannot display complex graphics or colors.
• Lower versatility compared to modern graphic LCD or OLED screens.

Notices: What is TN Technology?

TN (Twisted Nematic)

Its working principle is: that there are polarizers on the upper and lower layers of the panel, and the transmission directions of the two polarizers are perpendicular to each other. The liquid crystal molecules are arranged in a 90° twist from the upper layer to the lower layer in space.

When no power supply voltage is applied, the liquid crystal is in a natural state, and the light emitted from the lower layer will be twisted 90° after passing through the liquid crystal interlayer so that it can pass smoothly through the upper layer.

When the power supply voltage is applied between the two layers, an electric field is generated. At this time, the liquid crystal will deflect and arrange vertically, and the light will not be twisted. So the light cannot pass through the lower layer.

This realizes the control of the backlight illumination pixel.

Common Applications

• Digital Clocks: 7-segment displays for time representation.
• Calculators: Basic numerical display.
• Home Appliances: Used in devices like microwaves, washing machines, and air conditioners.
• Medical Devices: Blood pressure monitors and glucometers.
• Automotive: Dashboards and odometers.
• Industrial Equipment: Meters and monitoring tools.
