Segment Liquid Crystal Displays

Segment LCDs, also called static displays or glass-only displays, are constructed of two pieces of ITO (Indium tin oxide) glass with a twisted nematic fluid sandwiched in between. A static display is a segment display with one pin for every one segment.


These displays are still one of the most popular technologies in use and the majority of them are custom. Many people think the process of designing a custom segment liquid crystal display is complicated and too complex to be understood except for a few experienced people. But after designing custom LCDs for over 14 years, it can be said that just about anyone can select the best options for their product.


In other words, you don’t have to be an engineer, or have a PHD from MIT to design a custom LCD for your application. So instead of offering a list of technical terms and equations, these are the different options available.
