Abstract
The present invention provides a method for ambient light detection, proximity sensing, and ambient light charging applied to a panel. The method includes: providing a display panel, wherein the display panel comprises a plurality of pixels with PN junctions units in a display area; and providing a driving circuit, wherein the driving circuit drives each display pixel or each PN junction unit through a display mode, a standby mode, and a blanking time, so that part of each display pixel or each PN junction unit is used to perform a display function and part of each display pixel or each PN junction unit is used to carry out the ambient light detection, proximity sensing, or ambient light charging.
