Energy Conservation of Video Displays via Hardware Scrollbar

Disclosed is a system and method for Energy Conservation of Video Displays via Hardware Scroll bar.

When reading on an LCD display, a user tends to only look at a specific portion of the screen at a time, wasting some amount of energy on the rest of the screen that is not relevant at the moment. For example, on electronic reading devices such as an ebook, a user will be reading paragraphs of the ebook but only a specific area of the screen needs to be lit at a particular time. By only lighting up a section (e.g. a third of the screen) energy savings could be obtained.

Enabling art exists to display banners on a full LCD display in auxiliary energy-saving mode. However, these are driven by the type of input and only to display information coming from the external devices. The disclosed system enables the user of the screen display to move the section of the screen that is lit around by using a scroll-bar-like mechanism, be it hardware or software. When a user desires to enter into this type of energy saving mode (e.g. when they start reading lengthy texts on the screen), a portion of the screen will be lit leaving the rest of the screen off. Once the user is done reading that section, the user taps on the scroll-bar to move to the next section of the screen and so on until done reading the entire screen in sections.

The following figures illustrates this concept
