Abstract
Description

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.
[0032] Please refer to Figures 1, 2 and 3. In the related art, the display panel includes multiple row gate control circuits, for example, it may include a first row gate control circuit 1, a second row gate control circuit 2, a third row gate control circuit 3 and a fourth row gate control circuit 4. The signal input terminal 5 transmits the scanning signal to the multiple row gate control circuits through the transmission signal line 6, and the row gate control circuit transmits the voltage to the pixel circuit 8 in the display area through the output signal line 7; wherein the first row gate control circuit 1 and the third row gate control circuit 3 are directly connected and connected to the transmission signal line 6, and the second row gate control circuit 2 and the fourth row gate control circuit 4 are directly connected and connected to the transmission signal line 6; during the driving process of the display panel, the multiple gate control circuits perform row-by-row scanning. When the second row gate control circuit 2 and the fourth row gate control circuit 4 charge the pixel circuit 8, the load of the transmission signal line 6 will increase, thereby The voltage in the transmission signal line 6 decreases, causing the voltage transmitted to the first-row gate control circuit 1 to decrease, resulting in a sharp corner A as shown in Figure 2. When the third-row gate control circuit 3 charges the pixel circuit 8, the load on the transmission signal line 6 will increase, and the voltage in the transmission signal line 6 will decrease, causing the voltage transmitted to the first-row gate control circuit 1 to decrease, resulting in a sharp corner B as shown in Figure 2. Since the third-row gate control circuit 3 is directly connected to the first-row gate control circuit 1, the third-row gate control circuit 3 has a greater impact on the voltage in the first-row gate control circuit 1 when charging. Therefore, the degree of decrease in sharp corner B is greater than the degree of decrease in sharp corner A. Since the potentials in other row gate control circuits will also be affected by the first-row gate control circuit 1 as described above, the brightness of different rows in the display panel will fluctuate as shown in Figure 3, resulting in the display panel showing fine horizontal stripes and uneven display.

[0098] Further, please combine Figures 5 and 7. In the embodiment of the present application, the first output signal line 113 is connected to the gate of the compensation transistor T03, that is, the output signal of the first output signal line 113 is the second scanning signal NscanT3; in one embodiment, the compensation transistor T03 is an N-type thin film transistor, then the voltage loaded on the binding terminal 12 electrically connected to the first input signal line 13 and the voltage loaded on the binding terminal 12 electrically connected to the second input signal line 14 are both high levels.
[0099] It can be understood that the compensation transistor T03 is connected to the first electrode and the gate of the driving transistor T01. Therefore, if the signal transmitted in the first input signal line 13 and the second input signal line 14 is unstable, the voltage loaded on the gate of the compensation transistor T03 will also be unstable. Since there is a parasitic capacitance between the gate of the compensation transistor T03 and the gate of the driving transistor T01, the voltage fluctuation on the gate of the compensation transistor T03 will cause the gate of the driving transistor T01 to fluctuate, thereby affecting the stability of the signal transmission in the driving transistor T01, making the electrical signal transmitted to the light-emitting device unstable, resulting in the display unevenness of fine horizontal stripes on the display panel.

[0121] It can be understood that the first gate control circuit 111 connected to the first input signal line 13 and the first gate control circuit 111 connected to the second input signal line 14 are different first gate control circuits 111 .
[0122] Furthermore, the second connection end 132 of the first input signal line 13 and the fourth connection end 142 of the second input signal line 14 are connected to the transfer signal line 19 , and the transfer signal line 19 is connected to the second connection end 132 and the fourth connection end 142 on the side of the bending area 104 away from the fan-out routing area 103 .
[0123] In one embodiment, the transfer signal line 19 extends along a first direction X, and the first direction X can be the direction in which the bending area 104 approaches the fan-out wiring area 103; it should be noted that when the third direction N is the direction in which the fan-out wiring area 103 approaches the display area 101, the first direction X is parallel to the third direction N.
[0124] Among them, the first input signal line 13 extends in a direction oblique to the first direction X in the fan-out routing area 103, the first input signal line 13 extends in the first direction X in the bending area 104, and the first input signal line 13 extends in a direction oblique to the first direction X between the bending area 104 and the transfer signal line 19.

[0126] It should be noted that, since the portion of the display panel located in the bending area 104 needs to be bent, the portion of the display panel located in the bending area 104 away from the fan-out wiring area 103 is bent to the back side, so that the flexible circuit board 20 and the circuit board 30 can be located on the back side of the display panel to reduce the border width of the display panel close to the fan-out wiring area 103. Therefore, in the embodiment of the present application, the first input signal line 13 and the second input signal line 14 are extended along the first direction X in the bending area 104, which can reduce the bending stress exerted on the first input signal line 13 and the second input signal line 14. In addition, the binding terminal 12 and the first gate drive circuit 11 are not aligned. Therefore, in the embodiment of the present application, the first input signal line 13 and the second input signal line 14 are extended in a direction oblique to the first direction X in the area within the fan-out wiring area 103 and between the bending area 104 and the transfer signal line 19, so that the first input signal line 13 and the second input signal line 14 can be connected to the first gate drive circuit 11.
[0127] In one embodiment, through holes may be provided in the bending region 104 of the first input signal line 13 and the second input signal line 14 to improve the bending ability of the first input signal line 13 and the second input signal line 14 , and the arrangement of the through holes is not limited in the embodiment of the present application.

[0129] In one embodiment, the source-drain layer includes a transfer signal line 19. According to the process precision limitation of the source-drain layer, the length of the transfer signal line 19 along the first direction X is greater than or equal to 100 microns to avoid short circuits between the first input signal line 13, the second input signal line 14 and the transfer signal line 19 and the adjacent binding terminals 12 during the connection process.
[0130] In one embodiment, the gate layer includes a transfer signal line 19. According to the process precision limitation of the gate layer, the length of the transfer signal line 19 along the first direction X is greater than or equal to 20 microns to avoid short circuits between the first input signal line 13, the second input signal line 14 and the transfer signal line 19 and the adjacent binding terminals 12 during the connection process.
[0131] Furthermore, the first input signal line 13 includes multiple first line segments, and the multiple first line segments are independently located in the source and drain layer or the gate layer, that is, each first line segment can be selected to be located in the source and drain layer or the gate layer according to actual needs; for example, the first line segment of the first input signal line 13 located between the transfer signal line 19 and the bending area 104 can be located in the source and drain layer, the first line segment of the first input signal line 13 located in the bending area 104 can be located in the source and drain layer, and the first line segment of the first input signal line 13 located in the fan-out routing area 103 can be located in the gate layer.
[0132] The second input signal line 14 includes multiple second line segments, and the multiple second line segments are independently located in the source and drain layer or the gate layer, that is, each second line segment can be selected to be located in the source and drain layer or the gate layer according to actual needs; for example, the second line segment of the second input signal line 14 located between the transfer signal line 19 and the bending area 104 can be located in the source and drain layer, the second line segment of the second input signal line 14 located in the bending area 104 can be located in the source and drain layer, and the second line segment of the second input signal line 14 located in the fan-out routing area 103 can be located in the gate layer.
[0133] Please refer to Figures 5, 7, 9, 10 and 11. Since the connection points between the first input signal line 13 and the first gate drive circuit 11 and the connection points between the second input signal line 14 and the first gate drive circuit 11 are farther in the embodiment of the present application, the mutual influence between the signal transmission in the first input signal line 13 and the signal transmission in the second input signal line 14 is reduced, so that the sharp angle A appearing in the second scanning signal NscanT3 connected to the gate of the compensation transistor T03 is changed to the sharp angle a, and the degree of decrease in the potential of the second scanning signal NscanT3 at the sharp angle a is less than the degree of decrease at the sharp angle A, that is, the embodiment of the present application can effectively reduce the mutual influence between the signal transmission in the first input signal line 13 and the signal transmission in the second input signal line 14.
[0134] In one embodiment, a plurality of pixel driving circuits 16 are arranged in multiple rows and columns along the third direction N and the second direction M, wherein the first gate control circuit 111 connected to the first input signal line 13 can be connected to the pixel driving circuits 16 in odd rows, and the first gate control circuit 111 connected to the second input signal line 14 can be connected to the pixel driving circuits 16 in even rows; wherein the first scanning signal Pscan charges and turns on the switching transistors T02 in the pixel driving circuits 16 in the odd rows and the second scanning signal NscanT3 The time periods when the sharp corners B appear are staggered, and the time periods when the second scanning signal Pscan charges and turns on the switching transistor T02 in the pixel driving circuit 16 located in the even rows are staggered with the time periods when the sharp corners B appear in the second scanning signal NscanT3; since the second scanning signal NscanT3 will have a large downward fluctuation at the sharp corners B, the stage of data writing in the pixel driving circuit 16 in the embodiment of the present application is staggered with the time period when the sharp corners B appear in the second scanning signal NscanT3, so as to improve the stability of the pixel driving circuit 16 during the driving process.
[0135] Furthermore, one of the time period during which the first scanning signal Pscan charges and turns on the switching transistor T02 in the pixel driving circuit 16 located in the odd rows, and the time period during which the second scanning signal Pscan charges and turns on the switching transistor T02 in the pixel driving circuit 16 located in the even rows can be overlapped with the time period during which the sharp corner a appears in the second scanning signal NscanT3, while the other can be overlapped with the time period during which no sharp corner appears in the second scanning signal NscanT3.
[0136] Specifically, when the switching transistor T02 in the pixel driving circuit 16 located in the preset odd row is turned on, the compensation transistor T03 in the pixel driving circuit 16 located in the odd rows other than the preset odd row is not charged; when the switching transistor T02 in the pixel driving circuit 16 located in the preset even row is turned on, the compensation transistor T03 in the pixel driving circuit 16 located in the even rows other than the preset even row is not charged.
[0137] In addition, when the switching transistor T02 in the pixel driving circuit 16 located in the preset odd row is turned on, the compensation transistor T03 in the pixel driving circuit 16 located in the even row is charged, or when the switching transistor T02 in the pixel driving circuit 16 located in the preset even row is turned on, the compensation transistor T03 in the pixel driving circuit 16 located in the odd row is charged.
[0138] Furthermore, the embodiment of the present application performs brightness simulation verification on the display panels shown in Figures 1 and 5, and provides a pair of proportions and an embodiment. In the comparative example, the connection scheme shown in Figure 1 is adopted, and in the embodiment, the connection scheme shown in Figure 5 is adopted, and the brightness simulation data obtained is shown in Table 1 below.
[0139] Table 1 Brightness simulation data table
[0140] Comparative Example: Nscan T3 has a smaller sharp corner size (mV): 15246; odd-numbered line brightness (nit): 137.8135.7; even-numbered line brightness (nit): 132.3134.4; odd-even line difference: 4.07%0.96%
[0141] It can be seen from Table 1 above that the embodiment of the present application can effectively reduce the size of the smaller sharp corners appearing in the NscanT3 signal, and effectively reduce the luminous brightness of pixels in odd and even rows, thereby improving the display uniformity of the display panel.
[0142] Continuing from the above, the embodiment of the present application sets the connection point of the first input signal line 13 and the second input signal line 14 on the side of the bending area 104 away from the fan-out routing area 103, thereby making the connection point between the first input signal line 13 and the first gate drive circuit 11 and the connection point between the second input signal line 14 and the first gate drive circuit 11 farther, reducing the mutual influence between the signal transmission in the first input signal line 13 and the signal transmission in the second input signal line 14, and can improve the transmission stability of the signals in the first input signal line 13 and the second input signal line 14, improve the stability of the high-level signal output by the first gate control circuit 111, and improve the stability of the gate signals of the compensation transistor T03 and the driving transistor T01, thereby improving the display uniformity of the display panel.
[0143] In another embodiment of the present application, referring to FIG. 4 , FIG. 12 and FIG. 13 , the difference between this embodiment and the embodiment shown in FIG. 5 is that the first input signal line 13 and the second input signal line 14 are connected to different binding terminals 12 .
[0144] Specifically, the display panel includes multiple binding terminals 12, the second connection end 132 of the first input signal line 13 passes through the fan-out routing area 103 and the bending area 104 and is connected to one binding terminal 12, and the fourth end of the second input signal line 14 passes through the fan-out routing area 103 and the bending area 104 and is connected to another binding terminal 12.
[0145] The voltage loaded in the binding terminal 12 connected to the first input signal line 13 and the voltage loaded in the binding terminal 12 connected to the second input signal line 14 are both provided by the driver chip 31 on the circuit board 30, and the voltages loaded in both are the same, which are the same high-level signals.
[0146] Continuing from the above, the embodiment of the present application connects the first input signal line 13 and the second input signal line 14 to two binding terminals 12 respectively, thereby reducing the mutual influence between the signal transmission in the first input signal line 13 and the signal transmission in the second input signal line 14, and can improve the transmission stability of the signals in the first input signal line 13 and the second input signal line 14, improve the stability of the high-level signal output by the first gate control circuit 111, and improve the stability of the gate signals of the compensation transistor T03 and the driving transistor T01, thereby improving the display uniformity of the display panel.
[0147] In another embodiment of the present application, please refer to Figures 4, 14 and 15.

[0151] Among them, the second output signal line 114 is used to transmit the signals in the second gate control circuit 112 and the fourth gate control circuit 152 to the gate of the first reset transistor T04. Since there is a parasitic capacitance between the gate of the first reset transistor T04 and the gate of the driving transistor T01, if the gate potential of the first reset transistor T04 fluctuates, the gate potential of the driving transistor T01 will also fluctuate, causing the display panel to produce uneven display.

[0159] Continuing from the above, the embodiment of the present application sets the connection point of the first input signal line 13 and the second input signal line 14 on the side of the bending area 104 away from the fan-out routing area 103, thereby making the connection point between the first input signal line 13 and the first gate control circuit 111 and the connection point between the second input signal line 14 and the second gate control circuit 112 farther apart, reducing the mutual influence between the signal transmission in the first input signal line 13 and the signal transmission in the second input signal line 14, and can improve the transmission stability of the signals in the first input signal line 13 and the second input signal line 14, improve the stability of the high-level signal output by the first gate control circuit 111, and improve the stability of the gate signals of the compensation transistor T03, the first reset transistor T04 and the driving transistor T01, thereby improving the display uniformity of the display panel.
