Powertip’s innovative FS-LCD provides high colour saturation, fast response time, low power consumption and is a low cost alternative to full colour TFT LCD.
FS-LCD technology is suited for custom design segment/static type displays and with the use of an RGB LED backlight each segment can display one of eight colours (RED, GREEN, BLUE, YELLOW, CYAN, PURPLE, BLACK, WHITE) to create a visually high impact display. The principle of field sequential technology applies to the visual staying phenomenon, the full colour pallet is divided into RGB sub-frames which are presented sequentially, very fast. The driving frequency needs to be three times faster than a normal colour display, which means more than 180Hz to produce each sub-frame which requires a very fast crystal with a response time of less than 5ms.
