Passive LCD

You are here

A passive LCD is a low cost option when a display is needed for an application that doesn’t require a high performance display. The difference between a passive-matrix and an active-matrix LCD is that the passive matrix has a grid of horizontal and vertical wires and at the intersection there is an LCD element that makes a single pixel. The active-matrix LCD has a transistor on each pixel, which allows for more contrast, higher resolution and faster response time.

Advantages:

  • Competitive cost
  • Ideal for small applications

Applications:

  • Wearables
  • Medical
  • Transportation
  • Gaming
  • Military
  • Industrial
  • Instrumentation
  • Appliances

Different applications require different customizations. Our team of Display Engineers will work with you every step of the way to make sure you get the best display solution for the product that you are designing.

When should you consider creating a custom display?

  • If you are creating a new design and your volume is high enough to justify the price difference between a standard and a custom display (most of the times it’s just pennies, so it’s worth it!)
  • If you already have a design and need a display that matches your design

Most of the time our customers start with a standard off-the-shelf product and quickly realize that they need to make changes to be able to make the display fit their designs.
