  • Patent number: 11605352
    Abstract: Provided is a display panel including n pixel sets. Each pixel set includes 2m pixel rows arranged along a first direction. n and m are positive integers. Each pixel row includes pixel circuits arranged along a second direction intersecting with the first direction. Each pixel circuit includes a driving transistor, a first reset module configured to transmit, in response to a first scan signal provided by a first scan signal line, a first reset signal provided by a first reset signal line to a gate electrode of the driving transistor, and a second reset module configured to transmit, in response to a second scan signal provided by a second scan signal line, a second reset signal provided by a second reset signal line to an anode of an organic light-emitting element. The gate electrode receives high and low levels that are configured to reset the gate electrode.

Each pixel row includes pixel circuits arranged along a second direction, and the second direction intersects with the first direction. Each pixel circuit includes: a driving transistor; a first reset module configured to transmit, in response to a first scan signal provided by a first scan signal line, a first reset signal provided by a first reset signal line to a gate electrode of the driving transistor, the first reset signal including alternating high and low levels; and a second reset module configured to transmit, in response to a second scan signal provided by a second scan signal line, a second reset signal provided by a second reset signal line to an anode of an organic light-emitting element.

  • Patent number: 11158694
    Abstract: A display panel and a display device are provided. By simplifying the design of a part of a pixel drive circuit on a drive array substrate in a bending region of the display panel, the number of a drive transistor and other switching control tubes having the largest area in a partial region of the pixel drive circuit are reduced. Moreover, by removing an inorganic insulation layer having a larger stress, an organic buffer layer having a larger elastic modulus is filled. Therefore, the bending region has good bendability or foldability.

  • Patent number: 10520978
    Abstract: A foldable display panel, including: a first non-folding region, a folding region, and a second non-folding region arranged in the first direction; a plurality of gate lines; a plurality of data lines having first and second data lines; a plurality of first data pins located in the first non-folding region; a plurality of second data pins located in the second non-folding region; a plurality of first data leads; and a plurality of second data leads. The plurality of gate lines extends in the first direction from the first non-folding region, passes through the folding region and extends to the second non-folding region. The first data lines are electrically connected to the plurality of first data pins, and the second data lines are electrically connected to the plurality of second data pins. A folding axis of the foldable display panel is substantially parallel to the plurality of data lines.
