FAQ
What is an LCD Display? An LCD display is a flat-panel display technology that uses liquid crystals to produce images or video. Unlike older CRT (Cathode Ray Tube) displays, LCDs don’t use a beam of electrons to create light. Instead, liquid crystals are manipulated by electrical fields to control the passage of light, allowing for …
1. Twisted Nematic (TN) Panels How They Work TN panels are the oldest and most basic type of LCD panel. In a TN panel, liquid crystals are aligned in a twisted formation when no voltage is applied. When voltage is introduced, the crystals twist to control the passage of light through the display. Advantages Disadvantages …
1. Clear and Readable Information One of the most significant benefits of LED dot matrix displays is their ability to present clear, easily readable information. These displays use a matrix of LEDs that light up in patterns to form alphanumeric characters, symbols, and even graphics. This makes it easy for passengers to read and understand …
