  • Publication number: 20240361652
    Abstract: The present application provides a display panel and a manufacturing method thereof, and an electronic device. The display panel includes a light-transmitting region and a light-shielding region disposed at a periphery of the light-transmitting region. A thickness of a passivation layer of the display panel in the light-transmitting region is less than a thickness of the passivation layer in the light-shielding region, so as to reduce a thickness of an insulating layer between a pixel electrode and a common electrode. In this way, when a certain electric field is formed, a driving voltage which is required can be reduced, so as to reduce power consumption of the display panel, thereby alleviating an urgent need to reduce power consumption of display screen in prior art.
