LCD driver power saving during evaluation

An LCD power saving method which saves power consumption during normal operation of the LCD panel comprising the steps of:

• providing an interlacing mode to the access of the common or backplane addresses, and
• providing a non-interlacing mode to the access of the common or backplane addresses, and
• selecting of said interlace or non-interlace modes depending on content of display data by going into a data-dependent mode of operation which utilizes selection logic for forcing pre-selected display data, which is know to provide optimum low power testing environment.

An LCD, liquid crystal display, driver power saving apparatus comprising the means for:

• interlacing the access of common or backplane addresses to a LCD, or
• non-interlacing the access of common or backplane addresses to a LCD, wherein selecting said interlacing or said non-interlacing to provide optimum power saving depends on the content of display data, wherein power consumption is saved during the testing and evaluation of said LCD, by going into a data-dependent mode of operation which utilizes selection logic for forcing pre-selected display data, which is known to provide optimum low power testing environment.
