Battery with remaining electrical power display function and method of the same
First Claim
1. An electronic device comprising:
- a battery comprising a power storage unit for storing electrical power, and a display module placed on the surface of the battery, the display module being a magnetic powder plate comprising a plurality of magnetic display units;
a power detector selectively coupled to the battery, and generating a remaining power signal to indicate the electrical power stored in the battery when the power detector is coupled to the battery; and
a display control module receiving the remaining power signal to control the display module;
wherein when the battery is coupled to the power detector, the display control module controls the display module to show a remaining power display corresponding to the remaining power signal; and
when the battery is separated from the power detector, the display module is out of the control of the display control module but substantially keeps showing the remaining power display.

Abstract
This invention provides an electronic device that has a battery with a power storage unit and a display module, a power detector and a display control module. The power storage unit is for storing electrical power and the display module is placed on the surface of the battery. The power detector is selectively coupled to the battery, and generates a remaining power signal after detecting the remaining power in the battery. The remaining power signal is used to control the display control module. When the power detector is selectively coupled to the battery, the display module shows the current remaining power in response to the action of the display control module. When the power detector is separated from the battery, the display module is essentially capable of maintaining the showing of remaining power.

8. A combination of an electronic device and a battery, comprising:
-
a battery comprising a power storage unit for storing electrical power, and a display module placed on the surface of the battery, the display module being a magnetic powder plate; a power detector selectively coupled to the battery, and generating a remaining power signal to indicate the electrical power stored in the battery when the power detector is coupled to the battery; and a display control module, placed on the electronic device and electrically coupling to the power detector, for controlling, based on the remaining power signal, the display module positioned within an exerting range to switch between a first displaying state and a second displaying state; wherein, when the battery is coupled to the power detector and the power detector detects that the power of the battery is higher than a predetermined value, the power detector outputs a first signal to control the display control module, so as to make the display module show the first displaying state; wherein, when the battery is coupled to the power detector and the power detector detects that the power of the battery is lower than the predetermined value, the power detector outputs a second signal to control the display control module, so as to make the display module show the second displaying state; and wherein, after the battery is separated from the electronic device, the display module is out of the exerting range of the display control module, but the display module substantially keeps showing one of the first displaying state and the second displaying state. - View Dependent Claims (9, 10, 11, 12, 13)

16. A method of status display in an electronic device, the electronic device being detachably connected to an external unit and comprising a display module placed on a surface of the electronic device to indicate a current status of the electronic device, the display module being controlled by a display control module, the display module being a magnetic powder plate comprising a plurality of magnetic display units, the method comprising:
-
detecting a current status of the electronic device by connecting the electronic device with the external unit to generate a status signal; the display control module controlling the display module to show the current status of the electronic device according to the status signal; and separating the external unit from the electronic device wherein when the display module is beyond the control of the display control module, the display module still substantially shows the current status of the electronic device; wherein the external unit is a detector to detect remaining power of a battery of the electronic device and the status signal is a remaining power signal. - View Dependent Claims (17)
