Patents by Inventor Bichan ZHAO

Bichan ZHAO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12386227
    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.

  • Publication number: 20250048732
    Abstract: The disclosure provides a display panel and a preparation method thereof. The display panel includes an array substrate and an opposite substrate. The array substrate includes a first substrate, a common electrode layer, a first metal layer, a second substrate, and a light-shielding layer. The common electrode layer includes a common electrode, a first electrode, and a groove, and the groove is disposed between the common electrode and the first electrode. The light-shielding layer includes a light-shielding part, and an orthographic projection of the light-shielding part on the first substrate covers an orthographic projection of the first electrode on the first substrate, an orthographic projection of the second electrode on the first substrate, and an orthographic projection of the groove on the first substrate.
