摘要: A quick-response frequency-voltage converting circuit which generates a voltage signal responding to a reciprocal of the period of an input signal, and sample-holds this voltage signal at the end of one period, and thereby can obtain a voltage responding to the frequency of the input signal in one period.

摘要: A projection type display apparatus that projects video onto a screen includes a liquid crystal panel using polymer-dispersed liquid crystal that disperses light when a voltage is applied and that transmits light when a voltage is not applied, being attached to an apparatus body 2 as a screen 1; and the video output from the apparatus body 2 is projected onto the screen 1 from the front side. Accordingly, there is provided the projection type display apparatus suitable for use in small space such as at home, in which a place for setting the apparatus is flexibly selected and the feeling of oppression is mitigated when the apparatus is not used.
