Abstract
The invention provides a carryon device having functions of both data displaying and timing, which is characterized in that a Super Twisted-Nematic liquid crystal display and a Twisted-Nematic liquid crystal display are used to display data and time previously stored in the device or downloaded from external devices, respectively, wherein two separate batteries are provided to power these two displays so as to achieve an effect of increasing the efficiency of power usage.
Claims17
A carryon device having functions of both data displaying and timing, comprising:
- a case having a first wall, a second wall facing the first wall and at least one third wall located between the first wall and the second wall to demarcate a receiving space;
- a circuit unit placed in the receiving space of the case and has functions of both data processing, timing, and action controlling of each member;
- a memory controlled by the circuit unit and is used for data storage;
- a Super Twisted-Nematic liquid crystal display implanted on the wall of the case and is electrically connected to the circuit unit, for displaying data stored in the memory under the control of the circuit unit;
- a Twisted-Nematic liquid crystal display implanted on the wall of the case and is electrically connected to the circuit unit, for displaying time of the circuit unit, and the Twisted-Nematic liquid crystal display has a smaller size than the Super Twisted-Nematic liquid crystal display;
- and
- two batteries for supplying electric power required by the Super Twisted-Nematic liquid crystal display and the Twisted-Nematic liquid crystal display as well as other corresponding members of the carryon device.
