Abstract
A display includes a plurality of display arrays, such as a time display section (37), a chronological display section (38), and a chronological split display section (39). An upper or lower polarizer is provided with a light modulating section having a reflection type polarizer. To display only the time, the chronological display section (38) and the chronological split display section (39) are shielded by the light modulating section. For chronological display, the chronological display section (38) is lit, and the chronological split display (39) is displayed or shielded as required by a shutter function.
Claims19
An electronic device having a display section for displaying information and a shutter control means, wherein
- the display section, which has a plurality of display arrays including at least a time display and a plurality of other information display arrays, has a light modulating section, having above or below the display section a reflection type polarizer, for varying a light axis of a transmitting light, wherein said light modulating section includes a shutter device adapted to selectively shield at least one of said other information display arrays, and wherein said shutter control means includes a shutter open/close circuit and a shutter driving circuit both adapted to operate said shutter device.
An electronic device having a display section and a shutter control means, wherein the display section, which is able to display at least time and other information, comprises:
- an analog time display section;
- a digital display section stacked or put side by side with the analog time display section;
- and
- a light modulating section for varying a light axis of a transmitting light above the analog time display section and the digital display section, wherein said light modulating section includes a shutter device adapted to selectively shield at least one of the analog time display section or the digital display section;
- wherein said shutter control means includes a shutter open/close circuit and a shutter driving circuit both adapted to operate said shutter device.
An electronic device having a display section capable of displaying information in a form of
- a liquid crystal display electronic watch having information preparation means for preparing information,
- an LCD device for displaying the information,
- a shutter device adapted to be electronically operated by a shutter open/close circuit and a shutter driving circuit, and
- driving means for driving the LCD device, comprising:
- an external switch for switching driving or not driving of display of the LCD device by the driving means, wherein the LCD device has at least one reflection type polarizer, and either a segment being driven by the driving means or a segment being not driven by the driving means presents a metallic appearance, the segments constituting the LCD display and the segments being controlled to be driven sequentially.
