TicWatch Pro’s Layered Display technology (patent pending) is an innovative breakthrough, enabling the user to switch between an FSTN (Film compensated Super Twisted Nematic) LCD display and an OLED display that sit on top of one another. The FSTN display (top layer) is a transparent LCD display chosen due to its low power consumption, high visibility in direct sunlight, and transparent quality when not turned on. This is important in order to ensure the OLED (bottom layer) display’s brightness and colors aren’t compromised when in use.
