Existing display technologies face challenges in achieving narrow-border or borderless designs due to the physical space required for circuit lines, which affects the screen-to-body ratio and visual appeal.
The display panel incorporates a fanout-in-panel (FIP) routing design that limits fanout lines to specific regions and utilizes in-panel fanout lines to connect signal lines to pads, with connecting lines extending across both display and peripheral areas, reducing the bottom border.
This design achieves a smaller bottom border, enhancing the screen-to-body ratio and improving display quality by minimizing interference between connecting lines.

[0035] The disclosure will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of some embodiments are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
[0036] The display products, such as smartphones, are moving towards narrow-border or even borderless designs. Currently, the common technique for narrowing the bottom border is Fanout-in-Panel (FIP) , which connects part of the data lines to the target subpixels through FIP insert lines in the display area, significantly reducing the bottom border.
[0037] FIG. 1 is a schematic diagram illustrating the structure of a portion of a related display panel. FIG. 1 illustrates a display panel that does not have FIP routing. Referring to FIG. 1, the display panel in some embodiments includes a display area DA, and a peripheral area outside of the display area DA. In one or more first regions R1, the peripheral area includes a pad area PAD having a plurality of pads PD for connecting to an integrated circuit. In one or more first regions R1, the peripheral area further includes at least a portion of a fanout area FOA having a plurality of fanout lines. The plurality of fanout lines connect a plurality of signal lines (e.g., a plurality of data lines) in the display area DA to the plurality of pads PD in the pad area PAD. In one or more second regions R2, the peripheral area includes a scan circuit SC (e.g., a gate on array) configured to provide control signals to the display area DA (e.g., gate signals to gate lines in the display area DA) . In one or more second regions R2, the peripheral area further includes a plurality of connecting lines CL connecting the scan circuit to the pad area PAD. The fanout area FOA in some embodiments is partially in the one or more first regions R1, and partially in the one or more second regions R2. The plurality of connecting lines CL in some embodiments are partially in the one or more first regions R1, and partially in the one or more second regions R2.
[0038] In a display panel that does not have FIP routing, the one or more second regions R2 include both the plurality of fanout lines and the plurality of connecting lines CL. The plurality of fanout lines may be fanout lines alternately in a first conductive layer and a second conductive layer. The plurality of connecting lines CL may be lines in a first conductive layer, a second conductive layer, and a third conductive layer. The layout of the plurality of fanout lines and the plurality of connecting lines CL in the display panel that does not have FIP routing results in a wider bottom border (e.g., the area from the display area DA to the pad area PAD) .
[0039] FIG. 2 is a schematic diagram illustrating the structure of a portion of a related display panel. FIG. 2 illustrate a display panel that has FIP routing. Referring to FIG. 2, the display panel in some embodiments includes a display area DA, and a peripheral area outside of the display area DA. In one or more first regions R1, the peripheral area includes a pad area PAD having a plurality of pads PD for connecting to an integrated circuit. In one or more first regions R1, the peripheral area further includes at least a portion of a fanout area FOA having a plurality of fanout lines. The plurality of fanout lines connect a plurality of signal lines (e.g., a plurality of data lines) in the display area DA to the plurality of pads PD in the pad area PAD. In one or more second regions R2, the peripheral area includes a scan circuit SC (e.g., a gate on array) configured to provide control signals to the display area DA (e.g., gate signals to gate lines in the display area DA) .

The plurality of fanout lines are absent in the one or more second regions R2. The plurality of connecting lines CL in some embodiments are partially in the one or more first regions R1, and partially in the one or more second regions R2.
[0040] In a display panel that only has FIP routing, the one or more second regions R2 include only the plurality of connecting lines CL, but not the plurality of fanout lines. The layout of the plurality of fanout lines and the plurality of connecting lines CL in the display panel that has FIP routing results in a smaller bottom border (e.g., the area from the display area DA to the pad area PAD) . The plurality of fanout lines may be fanout lines alternately in a first conductive layer and a second conductive layer.

The plurality of fanout lines may be fanout lines alternately in a first conductive layer and a second conductive layer. The plurality of connecting lines CL may be lines in a first conductive layer, a second conductive layer, and a third conductive layer.
