Method and apparatus for displaying electric power elements for video display appliance
First Claim
1. An apparatus for displaying electric power elements associated with a particular video display appliance displaying said elements, comprising:
- a power supply section for supplying a power to said video display appliance;
a key input section for a user'"'"'s selection of a display command selecting electric power elements to be displayed;
a detecting section for detecting a voltage and current supplied from the power supply section to said video display appliance;
an analog-to-digital converter for converting the voltage and current detected by the detecting section into digital signals;
an operational processing section for converting the digital signals into a power consumption value in response to a control signal output by a control section;
an on-screen display (OSD) generating section for processing the power consumption value received from the operational processing section to a form suitable for on-screen display; and
a display section for displaying the power consumption value in alphanumeric form on a predetermined region of the screen, said value indicating in a textual format at least one of the voltage and current currently being supplied to said video display appliance by the power supply section, and the voltage and current being supplied to said video display appliance in a standard state.

Abstract
A method and apparatus for displaying electric power elements for a video display appliance that can compute a voltage and current actually applied to the appliance and power consumption computed therefrom, and display them on a screen. The apparatus includes, a key input section for a user'"'"'s selection of a display command and display items of the electric power elements, a detecting section for detecting a voltage and current supplied from a power supply section, an operational processing section for converting the voltage and current into the power consumption in response to a control signal received from a control section, an OSD generating section and a display section for processing and displaying by an OSD the voltage, current, and power consumption on a predetermined region of the screen. The respective electric power elements in the standard state and in the present state can be displayed on the screen selectively and together, and thus the characteristics and power supply state of the appliance can be more conveniently confirmed.

6. A method of displaying electric power elements for a video display appliance comprising the steps of:
-
detecting a voltage and current supplied to the video display appliance;
processing, in response to receiving a user'"'"'s key input selecting a display command and display items of the electric power element values to be displayed on a screen of said video display appliance, the detected voltage and current to match the display items selected by the user and displaying the display item as an alphanumeric value with associated text according to a result of said processing on a predetermined region of the screen by an on-screen display; and
displaying, in an absence of receiving the user'"'"'s key input, no display item on the screen. - View Dependent Claims (7)
