Abstract

1515053 Electronic watches DAINI SEIKOSHA KK 10 Aug 1976 [27 Aug 1975] 33268/76 Heading G3T [Also in Division G5] To improve the calendar display provided by a segmental liquid crystal device in an electronic watch, the segmental electrodes are provided in overlapping relation on a number of stacked electrode plates. As shown the display also comprises front and rear polarizers 1, 10 and a reflector 11. A plate 2 carries electrodes 3 forming segments a, b, c, f, g, h- Fig. 4 - while plate 6 carries electrodes 5 forming segments d, e. The plates are separated by an insulator 4 and a common counter electrode 7 is provided on a further plate 8, the liquid crystal medium being referenced 9. Letters M, N, O, T can be displayed by energizing segments abch, abcf, acdg, ed respectively. A similar device with three stacked electrode plates, Fig. 5 (not shown), each carrying segments of three symbols, allows SUN, MON, TUE, WED, THU, FRI, SAT to be displayed.
