Abstract
Content
A new graphic-type FIP® (Fluorescent Indicator Panel) combines conventional FIP elements with a poly-Si thin-film transistor (TFT) active matrix (AM). The matrix is capable of incorporating memory function in each picture element to drive the phosphor in static mode.
A prototype device with 24 x 24 picture elements in a 12 x 12 mm size shows brightness levels exceeding 200 fL (600 cd/m2) at a 25-volt driving voltage. Its characteristics are stable after the sealing process at 450°C for about 30 minutes. With continuing improvement, this device will be available as a terminal display in an automotive navigation system.
