Abstract
PURPOSE: To secure the emboss-like display with the second blinking cycle for the watch using the fluorescent light irradiation liquid crystal display unit, by providing the constitution to ensure the passing through the liquid crystal cell at the outside of the hour and minute display regions and furthermore installing the light emitting element which gives the second blanking on the back of the above constitution.
CONSTITUTION: Polarizing plates 22 and 24 are provided at both sides of twisted nematic cell 16, and fluorescent panel 30 is put on the back of plate 24. Panel 30 is composed of the Plexiglas into which the fluorescent molecule is doped along with the material very easily reflective coated on both end faces and the wall of groove 34 respectively. Ambient light 60 enters panel 30 after transmitting through light absorption plate 40 to be delivered to the time display segment through rough surface 32. The second blanking light of light emitting diode 50 fixed at the position of colon 14 enters panel 30, and then the straight beam transmits twist nematic cell 26 to be delivered above colon 14. At the same time, the emitted light is supplied to hour and minute display parts 10 and 12 each, thus giving the emboss-like display based on the blinking cycle.
