摘要

The present application provides a display panel. The display panel includes a plurality of data lines, a plurality of constant voltage traces, and a plurality of drive traces located in a display area. The display panel further includes a first metal layer, a second metal layer, and a shield layer between the first metal layer and the second metal layer, wherein the first metal layer includes a gate trace, the shield layer includes a plurality of shield traces, and the second metal layer includes the drive trace. An overlap region of the drive trace and the gate trace on the shield layer overlaps with the shield trace.

說明書

  • the display panel includes a first sub-pixel and a second sub-pixel arranged in a second direction, a number of the drive traces included in the first sub-pixel extending in the first direction is greater than a number of the drive traces included in the second sub-pixel extending in the first direction, and the shield trace is disposed in the first sub-pixel, and an orthographic projection of the drive trace on the shield layer overlaps with the shield trace.
  • Beneficial Effects

    The present application provides a display panel including a drive circuit layer, wherein the drive circuit layer includes a plurality of data lines and a plurality of constant voltage traces located in a display area, and a plurality of drive traces electrically connected to the data lines and a drive chip. The drive circuit layer includes a first metal layer, a second metal layer, and a shield layer between the first metal layer and the second metal layer, the first metal layer includes a plurality of gate traces, the shield layer includes a plurality of shield traces electrically connected to the constant voltage traces, the second metal layer includes the drive traces, and an overlap region where an orthographic projection of at least a portion of the drive traces on the shield layer and an orthographic projection of at least a portion of the gate traces on the shield layer are overlapped overlaps with the shield traces. In the present application, the shield trace is provided between the drive trace and the gate trace, the shield trace is electrically connected to the constant voltage trace, and the signal between the drive trace and the gate trace is shielded by the shield trace, thereby weakening or eliminating interference of the signal in the drive trace on the signal in the gate trace, and improving the display quality of the display panel.
