Method for ambient light detection, proximity sensing, and ambient light charging applied to display panel

A method for ambient light detection, proximity sensing, and ambient light charging applied to a panel, comprising the following steps:

• 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;
• wherein the display function is carried out by using the display pixels of the display panel, and the functions of ambient light detection, proximity sensing, or ambient light charging may be switched by some of undisplayed pixels or all of the undisplayed pixels of the display panel, wherein the blanking time of the driving circuit comprises a horizontal blanking time and a vertical blanking time, the vertical blanking time has a corresponding vertical display time, a vertical blanking pulse time without display is inserted to the vertical display time for the ambient light detection or ambient light charging, and the horizontal blanking time has a corresponding horizontal display time, and a horizontal blanking pulse time without display is inserted to the horizontal display time for the ambient light detection or ambient light charging.
