A method for connecting two circuit boards characterized in that by using rubber connectors, each having an open part for receiving circuit boards, an edge of a first circuit board requiring connection inserted into the open part of the rubber connector, followed by pressing a second rubber connector against the circuit board to complete connection of the two circuit boards.

Circuit board connection

A DAP (Deformation of Aligned phase of Nematic) type liquid crystal display is enabled with a voltage having a periodically variable effective value. The displaying color of the DAP type liquid crystal display is changed by cyclic variation in the effective value of the applied voltage.

DAP Type liquid crystal display with means for obscuring viewing angle

Liquid crystal material suitable for use in small display devices and consisting of one or more biphenyl or terphenyl compounds and one or more ester compounds, whereby low threshold voltage characteristics of one type of compound are complemented by the low viscosity and good response characteristics of the other type of compound, and liquid crystal material having good overall characteristics is achieved.
