Segmented LCDs and graphic displays are a popular choice among products such as thermostats, kitchen appliances, medical devices, industrial meters, and more. A segmented LCD is an ideal solution for products that require a customizable cost-effective, low-power display option. Displaytech offers custom 7 segment displays in static or multiplex drive. 

About 7 Segment Displays

Segmented LCDs are monochrome liquid crystal displays where the elements on the panel are divided into segments which can either be visible (on) or hidden (off).

Advantages of a 7-Segment LCD Display

  • Low Cost

    Compared to other LCD screen technology, segmented displays offer a low cost custom solution for high volume applications.

  • High Contrast

    By design, a segmented display screen showcases dynamic contrast between visible and hidden elements.

  • Low Power Consumption

    This display type requires minimal power making it ideal for battery-powered devices.

Fluid Types for Segmented LCD Panels

TN (Twisted Nematic)

  • Most common segment display fluid
  • Lowest cost option

STN (Super Twisted Nematic)

  • Provides widest viewing angle
  • More expensive than TN

FSTN (Film Super Twisted Nematic)

  • Offers sharpest contrast
  • More expensive than TN

Drive Types for Seven-segmented Displays

Static Drive Type

  • Every segment gets its own unique pin 
  • Offers high contrast between off and on visibility
  • Limited space availability for complex designs since there may not be enough physical space to accommodate each segment having its own pin

Dynamic (Multiplex) Drive Type

  • Multiple segments assigned to one pin
  • Less pins needs to control the display
  • Loss of contrast between on and off visibility since one pin is handling multiple segments and therefore may never be completely powered off
  • Overcomes physical limitations that static drive type has
