Energy saving process for partial display utilization

Display screens in today's market have a static size and use a constant amount of energy regardless of whether the entire screen is being utilized. This model is not energy-efficient. Certain circumstances and parameters might require a smaller display size, thus providing an opportunity to consume less electricity.

Examples of this inefficiency are when standard definition content is viewed on a high definition display, or when wide screen content is viewed on a standard size display; the dimensions of the physical screen are different from the dimensions of the media. This results in vertical and/or horizontal bars around the edges of the display which are inactive and wasting energy. In addition, a viewer may wish to shrink the entire active screen size for reasons such as power conservation or comfort while sitting closer to the display.

This invention aims to save energy by not supplying power to these inactive areas outside of the active viewing area.

Current known solutions include:

• An approach concerned with the power of the individual pixels based on the picture in view. [1] The solution discussed here is concerned with the needed screen size based on a plurality of parameters and saving the energy according to these parameters.

• A consideration of the effects of the power setting to reduce "burn in". [2]

The core idea of our disclosure is a system, method and apparatus that detects the optimum needed screen size and reduce the electrical consumption of the screen when the virtual screen size becomes less than the maximum.

Such parameters include but are not limited to:

• The original recording of the show viewed that may not require full screen

• The distance between the screen and the viewer

• Manual size setting based on the viewer's preference

• A set goal of electrical consumption indicating an electrical spending threshold that, when reached within a defined period of time, triggers a reduction in the screen size to save electricity

This is a green technology that facilitates power savings on a high definition display either automatically or manually according to the content being displayed. On a
