[0071] The first ends of the plurality of second data signal lines are connected to the plurality of second data driving terminals one by one, and the second ends of the plurality of second data signal lines are connected to the data lines in the second display subpart 103 one by one. At this time, the number of the second data driving terminals is the same as the number of the data lines in the second display subpart 103.

[0072] In some embodiments, the display panel 100 further comprises a signal input circuit group located between the signal terminal part 105 and the first display subpart 102.

[0073] The signal input circuit group is connected between the first data signal line group 109 and the data lines in the first display subpart 102, and the signal input circuit group is connected between the second data signal line group 110 and the data lines in the second display subpart 103.

[0074] The signal input circuit group can be a multiplexing circuit.

One second data signal line is connected to a plurality of data lines in the second display subpart 103 through the signal input circuit group, thereby reducing the number of second data lines and the number of second data driving terminals.

[0076] In some embodiments, the signal input circuit group comprises a first signal input circuit group located on the side of the bending part 104 away from the second display subpart 103 and a second signal input circuit group located on the side of the bending part 104 away from the first display subpart 102.

[0078] By arranging the first signal input circuit group and the second signal input circuit group on both sides of the bending part 104, the signal input circuit groups can be arranged across the bending part 104, reducing the damage to the lines caused by repeated bending during use of the display panel 100.

[0081] When the signal input circuit groups are present, the corresponding reduction of the first data signal lines, the second data signal lines, the number of first data driving terminals, and the number of second data driving terminals also occurs. Preferably, the ratio of the number of data lines in the first display subpart 102 to the number of first data driving terminals is 2:1 or 3:1, and the ratio of the number of data lines in the second display subpart 103 to the number of second data driving terminals is 2:1 or 3:1.

[0082] In some embodiments, the ratio of the number of data lines in the first display subpart 102 to the number of data lines in the second display subpart 103 is positively correlated with the ratio of the display area of the first display subpart 102 to the display area of the second display subpart 103, and the ratio of the number of first data driving terminals to the number of second data driving terminals is also positively correlated with the ratio of the display area of the first display subpart 102 to the display area of the second display subpart 103. Preferably, the ratio of the number of first data driving terminals to the number of second data driving terminals is 2:1.

[0083] In some embodiments, the first display subpart 102 includes a first non-bending subpart close to the bending part 104, a second non-bending subpart away from the bending part 104, and a bending subpart between the first non-bending subpart and the second non-bending subpart.

[0085] The first width is less than or equal to a sum of the second width and the third width, and the first plane is parallel to a plane on which the first non-bent sub-portion is located. Preferably, the first width is less than or equal to the second width. By arranging the signal terminal portion 105 closer to the bent portion 104, the bending of the first signal line group 106 and the second signal line group 107 electrically connected to the signal terminal portion 105 is reduced, thereby reducing the problem of disconnection caused by repeated bending of the first display sub-portion 102 during use of the display panel 100. At the same time, the arrangement of the signal terminal portion 105 closer to the bent portion 104 is conducive to balancing the lengths of the first signal line group 106 and the second signal line group 107, so as to prevent the length of the second signal line group 107, especially the second scanning signal line, from being too long and increasing the risk of disconnection.

[0086] Please refer to Figures 4 to 5 In some embodiments, the display panel 100 further includes a substrate, and the signal terminal portion 105 is located on a side of the substrate close to a first display surface of the first display sub-portion 102.

[0087] The substrate includes at least one hollow portion 120, the hollow portion 120 is located between a first side of the display panel 100 and a first side of the first display sub-portion 102, and the hollow portion 120 is located in the bent portion 104, and the first side of the display panel 100 is located on a side of the signal terminal portion 105 away from the first display sub-portion 102.

[0088] The hollow portion 120 includes a first through hole having a first concave surface recessed toward the first side of the display panel 100. The first through hole also has a second concave surface recessed in a direction away from the first side of the display panel 100.

[0089] The hollow portion 120 further includes a second through hole, and the second through hole includes a third concave surface recessed toward a third side of the first display sub-portion 102.

[0090] The hollow portion 120 further includes a third through hole, and the third through hole includes a fourth concave surface recessed toward a third side of the second display sub-portion 103.

[0091] The first via hole, the second via hole, the third via hole and the fourth via hole are arranged away from the wire (for example, the second data signal line and the second scan signal line) passing through the bending portion 104.

[0092] By arranging the hollow portion 120, the bending stress of the substrate in the bending portion 104 is reduced, and the risk of breakage of the substrate and the wire (for example, the second data signal line and the second scan signal line) passing through the bending portion 104 is reduced.

[0093] In some embodiments, the second display surface of the second display sub-portion 103 and the first display surface are respectively located on opposite sides of the substrate.

[0094] In some embodiments, the display panel 100 further comprises a driving chip and a flexible circuit board 121 electrically connected to the driving chip. The display panel 100 can be a COG (Chip On Glass, chip directly bonded on glass) type display panel or a COF (Chip On Film, Chip On Film) type display panel.

[0095] When the display panel 100 is a COG type display panel, the signal terminal portion 105 is the driving chip, and the signal terminal portion 105 further comprises a bonding terminal, and the signal terminal portion 105 is electrically connected to the flexible circuit board 121 through the bonding terminal. The bonding terminal can be located between the first terminal group 112 and the first side of the display panel 100.

[0096] When the display panel 100 is a COF type display panel, the signal terminal portion 105 is electrically connected to the driving chip by being electrically connected to the Chip On Film, and at this time, the driving chip is fixed on the flexible circuit board 121.

[0097] In the embodiments of the present application, the signal terminal portion 105 is arranged on the side of the bending portion 104 away from the second display sub-portion 103 and close to the second side of the first display sub-portion 102, so that the signal terminal portion 105 can provide corresponding signals to the first display sub-portion 102 and the second display sub-portion 103, thereby reducing the use of the driving chip and the flexible circuit board and reducing the manufacturing cost of the display panel 100.
