Signum Panel is designed to replace the popular STN (Super-Twisted Nematic) LCD with the more popular and advanced TFT LCD. STN has become a pricy commodity as worldwide supply dries up. The lead-time and MOQ (Minimum Order Quantity) requirement are edging up. These disadvantages have made STN LCD a less attractive technology choice. However, there are still popular and mature applications. The de facto standard products, 240x64 and 240x128 STN LCD, are still widely adopted in industrial, medical, and commercial applications. The goal of Signum Panel is to be a direct substitute for these STN products.
