Abstract
1409006 Electronic watches SUWA SEIKOSHA KK 31 July 1973 [3 Aug 1972] 36361/73 Heading G3T [Also in Division G5] In an electronic timepiece having a liquid crystal display panel 8, the latter is fixed by means of a panel frame 9 to a base member 12 having electric contacts 15 to supply energizing signals to appropriate electrodes of the display panel. The display panel comprises plates 1, 2 separated by a nylon spacer 3 and with liquid crystal material 5 therebetween. An orifice (6), Figs. 1 and 2 (not shown) in the plate 1 is sealed, after filling with the material 5, by a metal pin (7). After assembly, the panel frame 9 conceals the inner edge of the spacer 3 and the pin (7). The base member 12 carries oscillator and drive circuitry 14. As screws 19 are tightened, the contacts 15 are resiliently deformed to give a desired contact pressure against connecting strips on the underside of the plate 1.
