Along the first direction X, the first bending region 21 and the second bending region 22 are respectively located at two sides of the front display region 10, as illustrated in fig. 1-3, the first bending region 21 and the second bending region 22 are respectively located at two sides of the front display region 10 and respectively serve as a left side surface and a right side surface of the display panel. The third bending region 23 is located at one side of the front display region 10 and serves as a lower side of the display panel along the second direction Y. Wherein the first direction X intersects the second direction Y.
The plurality of non-display areas include a first non-display area 31, a second non-display area 32 and a third non-display area 33, wherein the first bending area 21 is located between and connected to the first non-display area 31 and the front display area 10, the second bending area 22 is located between and connected to the second non-display area 32 and the front display area 10, and the third bending area 23 is located between and connected to the third non-display area 33 and the front display area 10. The first non-display area 31, the second non-display area 32 and the third non-display area 33 are all located on a side of the front display area 10 away from the light emitting surface, that is, the first non-display area 31, the second non-display area 32 and the third non-display area 33 are located on the lower surface of the display panel. That is, after the first bending region 21 is bent, the first non-display region 31 is turned over to the lower surface of the display panel and is parallel to the front display region 10, after the second bending region 22 is bent, the second non-display region 32 is turned over to the lower surface of the display panel and is parallel to the front display region 10, and after the third bending region 23 is bent, the third non-display region 33 is turned over to the lower surface of the display panel and is parallel to the front display region 10.

That is, the first edge 311 of the first non-display region 31 adjacent to the third non-display region 33 and the third edge 331 of the third non-display region 33 adjacent to the first non-display region 31 are parallel; the second edge 321 of the second non-display area 31 adjacent to the third non-display area 33 and the fourth edge 332 of the third non-display area 33 adjacent to the second non-display area 32 are parallel.
In addition, the projections of the third edge 331 and the fourth edge 332 in the display panel thickness direction Z are located between the projections of the first edge 311 and the second edge 312 in the display panel thickness direction Z, that is, the third non-display area 33 and the first non-display area 31 and the second non-display area 32 do not overlap in the display panel thickness direction Z.
Note that the thickness direction Z of the display panel is a direction substantially intersecting the maximum display area of the display panel, that is, the front display area 10, for example, when the upper surface of the front display area 10 is a flat surface, the thickness direction Z of the display panel is a direction perpendicular to the front display area 10. And the first direction X and the second direction Y are both perpendicular to the thickness direction Z of the display panel, and further, the first direction X may be perpendicular to the second direction Y.
In the present embodiment, the first non-display area 31, the second non-display area 32, and the third non-display area 33 are all disposed on the back side of the front display area 10, so that the front display of the display panel provided in the present embodiment in the first direction X can be frameless, and a frameless design can also be implemented below the front display of the display panel. The first non-display area 31, the second non-display area 32 and the third non-display area 33 are all areas where peripheral signal lines and/or peripheral circuits of the display area are disposed, in this embodiment, the third non-display area 33 is disposed away from the first non-display area 31 and the second non-display area 32 without overlapping, so that signal interference between the non-display areas can be avoided.
In addition, when the third non-display area 33 is disposed on the back of the front display 10, the edges of the third non-display area 33 close to the first non-display area 31 and the second non-display area 32 are parallel to the extending direction of the first non-display area 31 and the second non-display area 32, respectively, and the extending direction of the edge connected to the third bending area 23 is the first direction, i.e., the extending direction of the edge is parallel to the arrangement direction of the first non-display area 31 and the second non-display area 32, so that the third non-display area 33 is a regular structure such as a rectangle or a parallelogram disposed between the first non-display area 31 and the second non-display area 32. On one hand, a third non-display area 33 may be provided between the first non-display area 31 and the second non-display area 32 with a maximum spatial limitation; on the other hand, the third non-display area 33 may have a regular shape, which is advantageous for the arrangement of signal lines and circuits.
Similarly, the first non-display area 31 and the second non-display area 32 are also provided in a regular shape, which is advantageous for the arrangement of signal lines and circuits.
In one implementation manner of the embodiment, in order to transmit at least part of the signals in the display panel to the main board, the third non-display area 33 may be bonded to at least one of the driver chip and the flexible circuit board, and the bonding area increases a width of the third non-display area 33 along the second direction Y. In addition, due to the limitation of the binding width of the driver IC and the flexible printed circuit board FPC, the third non-display area 33 is provided with fan-shaped traces, so that the third non-display area 33 has a larger width in the second direction Y. The width of the third non-display area 33 in the second direction Y is generally larger than the width of the first non-display area 31 in the first direction X and larger than the width of the second non-display area 32 in the first direction X. In the embodiment, the adjacent edges of the first non-display area 31, the second non-display area 32 and the third non-display area 33 are parallel to each other, so that the first non-display area 31 and the second non-display area 32 are always in the same width structure along the second direction Y, which is favorable for the arrangement of circuits and signal lines therein.
Fig. 5 is another schematic diagram of the display panel shown in fig. 1 with the front display area facing downward.
As shown in fig. 2 and fig. 5, in an implementation manner of the present embodiment, along the first direction X, a distance between a first edge 311 of the first non-display area 31 close to the third edge 331 and a second edge 321 of the second non-display area 32 close to the fourth edge 332 is a first distance D1, and a distance between the third edge 331 and the fourth edge 332 of the third non-display area 33 is a second distance. Wherein D1 and D2 are both greater than 0.
As shown in fig. 2, D1 and D2 satisfy: d1 > D2, which can effectively avoid signal crosstalk between the signal lines/circuits in the third non-display area 33 and the signal lines/circuits in the first and second non-display areas 31 and 32.
As shown in fig. 5, D1 and D2 satisfy: d1 is D2, that is, the third edge 331 is immediately adjacent to the first edge 311 and the fourth edge 332 is immediately adjacent to the second edge 321, by such a design, it is possible to maximize the width of the third non-display area 33 in the first direction X while ensuring the width of the first and second non-display areas 31 and 32 in the first direction X, ensure the spacing between the signal lines provided in the third non-display area 33, reduce the risk of signal crosstalk, and reduce the difficulty of design.
