Abstract
An OLED touch display operation method is disclosed. The OLED touch display operation method includes the following steps: controlling a touch scan transition timing and a display multiplexer switching timing to maintain a specific equidistant relationship; when the OLED touch display performs display function, the OLED touch display performs touch scanning only for a part of display time, and stops touch scanning or performs touch voltage compensation scanning for another part of display time; and when being interfered by external noise, the OLED touch display performs touch scanning only in a blanking period out of the display time and the touch scanning frequency can be adjusted to avoid interference of external noise.
