Abstract

A portable electronic timepiece includes an electronic time-keeping device for developing electric time signals suitable for use as a time standard. The timepiece is equipped with a television receiver for receiving telecast TV signals and develops therefrom electric video signals representative of the video information contained in the telecast signals. Both the time signals and the video signals are applied through drive circuitry to a matrix indicator comprised of a plurality of longitudinal electrodes and a plurality of row electrodes. A switching circuit selectively applies the time or video signals to the matrix indicator for effecting display of either a time image or a video image.

Claims

1. A portable electronic timepiece comprising:

electronic time-keeping means for developing electric time signals suitable for use as a time standard;

receiving means for receiving a telecast video signal and developing therefrom electric video signals representative of the video information contained in the telecast video signal;

indicating means receptive of the electric time signals and the electric video signals for selectively visually displaying an image of the time and of the video information; and

switching means coacting with said time-keeping means and said receiving means for selectively switching the electric time and video signals to said indicating means to thereby select either the time image or the video information image to be displayed by said indicating means.

2. A portable electronic timepiece according to claim 1, wherein said indicating means comprises a matrix indicator comprised of a plurality of longitudinal electrodes and a plurality of row electrodes.

3. A portable electronic timepiece according to claim 1;

wherein said electronic timepiece comprises a wristwatch.

4. A portable electronic timepiece according to claim 1;

wherein said indicating means includes means for displaying either the time image or video information image on the whole display portion thereof.

5. In a portable electronic timepiece of the type having a crystal oscillating circuit for developing pulse signals suitable for use as a time standard:

a matrix indicator having a plurality of longitudinal electrodes and a plurality of row electrodes for visually displaying on the whole display portion thereof an image;

a receiver for receiving a telecast TV video signal and deriving therefrom an electric video signal corresponding to the information contained in the telecast TV video signal;

means responsive to the electric video signal including a row driving circuit and a longitudinal driving circuit for driving said matrix indicator to indicate a video image corresponding to the information contained in the TV video signal;

time-keeping means for counting the pulse signals from said oscillating circuit and deriving therefrom a time signal corresponding to time;

means responsive to said time signal including said row driving circuit and said longitudinal driving circuit and further including a transducer controlled by said pulse signals for driving said matrix indicator to indicate a time image corresponding to the time signal; and

switching means for selecting between the video and time images to be displayed by said matrix indicator.
