BACKGROUND

In the related art, when an Organic Light Emitting Diode (OLED) display updates an image, it is necessary to initialize and write pixel voltages to all rows of pixel circuits within one frame. And in some special images, such as the Always On Display (AOD) images, the AOD image is an image that controls the partial lighting of the screen without lighting up the entire mobile phone screen, a static image or a less updated image, most of the pixel circuits in the whole screen do not need to update the pixel voltage, that is, most of the pixel circuits can maintain the original display brightness through low-leakage low temperature polycrystalline oxide (LTPO) thin film transistor (TFT), and repeated flashing on these pixel circuits causes waste of power consumption.
