Abstract

A power device and a method for visualizing information thereof are provided. The power device is configured to provide operation power to at least one load. The power device comprises a display interface and a control circuit. The control circuit is configured to display a color icon by the display interface, so as to show at least one of a system status and a system setting of the power device by the color icon.

First claim

What is claimed is:

1. A power device for providing operation power to at least one load, the power device comprising:
a graphical liquid crystal display, comprising a monochromatic liquid crystal display and a color patterned transparent film having a plurality of color icons with different shapes; and
a control circuit, configured to display at least one of the color icons by the graphical liquid crystal display, so as to show at least one of a system status and a system setting of the power device by the displayed at least one of the color icons.

2. The power device as claimed in claim 1 , wherein the control circuit further controls the graphical liquid crystal display to blink the displayed at least one of the color icons, so as to show at least one of the system status and the system setting by the displayed at least one of the color icons.

3. The power device as claimed in claim 1 , wherein the graphical liquid crystal display comprises a touch panel, and the control circuit is further configured to receive, through the touch panel, the system setting inputted by a user.

4. The power device as claimed in claim 1 , further comprising an input interface, wherein the control circuit is further configured to receive, through the input interface, the system setting inputted by a user.

5. The power device as claimed in claim 4 , wherein the input interface comprises at least one button.

10. The power device as claimed in claim 7 , wherein the uninterruptible power system is a line-interactive uninterruptible power system, and the line-interactive uninterruptible power system further comprises an automatic voltage regulator, and the input unit comprises a first switch unit, the output unit comprises a second switch unit, the second voltage conversion unit comprises a DC-AC conversion circuit, and the first voltage conversion unit is a charging circuit.

11. A power device for providing operation power to at least one load, the power device comprising:
a graphical liquid crystal display, comprising a glass substrate with a color patterned coating, the color patterned coating having a plurality of color icons with different shapes; and
a control circuit, configured to display at least one of the color icons by the graphical liquid crystal display, so as to show at least one of a system status and a system setting of the power device by the displayed at least one of the color icons.

12. The power device as claimed in claim 11 , wherein the control circuit further controls the graphical liquid crystal display to blink the displayed at least one of the color icons, so as to show at least one of the system status and the system setting by the displayed at least one of the color icons.

13. The power device as claimed in claim 1 , wherein the graphical liquid crystal display comprises a touch panel, and the control circuit is further configured to receive, through the touch panel, the system setting inputted by a user.

14. The power device as claimed in claim 11 , further comprising an input interface, wherein the control circuit is further configured to receive, through the input interface, the system setting inputted by a user.

15. The power device as claimed in claim 14 , wherein the input interface comprises at least one button.

16. The power device as claimed in claim 11 , wherein the power device comprises an uninterruptible power system, an AC-DC converter, a DC-AC inverter, a DC-DC converter, a power distribution unit or an automatic transfer switch.
