Fig. 2 and fig. 3 are schematic structural diagrams of a display panel according to an embodiment of the present invention, and as shown in fig. 2, the display panel includes: a display area 1 and a non-display area 2 surrounding the display area; the display area comprises a bent display area 12 and a central display area 11 which are arranged along a first direction Y; the non-display area 2 includes a first non-display area 21 disposed on one side of the display area 1 in the second direction X, and the first non-display area 21 includes a bent non-display area 212 extending along the first direction Y and a central non-display area 211, in another embodiment, see fig. 7, wherein along the first direction Y, the central display area 11 is located between two bent display areas 12, and the central non-display area 211 is located between two bent non-display areas 212;
as shown in fig. 3, the display area 1 includes a plurality of pixels distributed in an array and a plurality of scan lines 6 arranged along a first direction Y and extending along a second direction X; the display panel further includes a pixel circuit 3 that drives the pixels to emit light; a plurality of driving circuits 5 are arranged in the non-display area 2, and the driving circuits 5 transmit scanning signals to the pixel circuits 3 through scanning lines 6; the driving circuit 5 comprises at least one first driving circuit 51 arranged in the bending non-display area 212, and the first driving circuit 51 is used for providing a first control signal for at least one row of pixel circuits 3 in the bending display area 12; and a plurality of second driving circuits 52 disposed in the central non-display area 211, each second driving circuit 52 providing a second control signal to at least one row of pixel circuits 3 located in the central display area 11, respectively;
wherein, in one frame display, each row of the pixel circuits 3 connected to each of the first drive circuits 51 receives N first control signals; each row of pixel circuits 3 connected to each second drive circuit 52 receives M second control signals. Wherein M and N are positive integers, and M is greater than N. That is, in one frame of display, the number of control signals output by the first driving circuit 51 in the bent non-display area is less than the number of control signals output by the second driving circuit 52 in the central non-display area 12, and because the number of control signals output by the first driving circuit 51 in the bent non-display area 212 is less, the structure of the first driving circuit 51 is simple, the number of transistors included is less, and the space of the bent non-display area 212 occupied by the first driving circuit 51 is small, so that the width of the bent non-display area is reduced, a narrow frame of the display panel is easily realized, and the display effect is improved.
Specifically, the number of the first driving circuits 51 in the bending non-display area may be equal to or different from the number of rows of the pixel circuits in the bending display area 12, that is, the number of the first driving circuits 51 in the bending non-display area 212 may be one or more.
For example, fig. 4 is a schematic diagram of a partially enlarged structure of the area a shown in fig. 1, and as shown in fig. 4, the number of the first driving circuits 51 located in the bending non-display area 212 is equal to the number of rows of the pixel circuits located in the bending display area 12, that is, in one frame display, the pixel circuits located in the bending display area 12 all receive N first control signals, that is, the circuit structures of the plurality of first driving circuits 51 providing N first control signals for one row of pixel circuits in the bending display area 12 are simple, so that the space of the bending non-display area 212 occupied by the first driving circuits 51 is small, thereby reducing the width of the whole bending non-display area 212, easily realizing a narrow frame of the display panel, and improving the display effect.
For example, fig. 5 is another partial enlarged structural schematic diagram of the area a shown in fig. 1, as shown in fig. 5, the bending display area 12 includes a first bending display area 121 and a second bending display area 122, wherein the first bending display area 121 is close to the central display area 11, wherein the driving circuit includes at least one first driving circuit 51 and at least one third driving circuit 53 located in the bending non-display area 212, wherein, in one frame of display, the at least one first driving circuit 51 provides N first control signals for the pixel circuits in the first bending display area 121, and the at least one third driving circuit 53 provides F third control signals for the pixel circuits in the second bending display area 122, where F and N are positive integers and F is greater than N, that is, in one frame of display, the number of the first bending control signals received by the pixel circuits in the second bending display area 122 is greater than the number of the third control signals received by the pixel circuits in the first bending display area 121 The number of signals is reduced, so that the width of the partially bent non-display region 212 can be reduced, and in addition, the display quality in the second bent display region 122 is higher than that in the first bent display region 121 because the structure of the pixel circuit in the second bent display region 122 is more complicated than that of the pixel circuit in the first bent display region 121, so that the display quality in the bent display region 12 is also improved.
Optionally, as described above, in one frame of display, the number of the second control signals received by the pixel circuits in the central display area 11 is M, where M is greater than N, and the number of the third control signals received by the pixel circuits in the second bending display area 122 is F, where F is greater than N, so M may be equal to M, or may not be equal to M.
For example, M may be equal to F (e.g., M is equal to three, and F is equal to three), that is, in one frame of display, the second driving circuit 52 located in the central non-display area 211 provides three second control signals, which may be two scanning signals S1, S2 and one emission control signal EM, for each row of pixel circuits located in the central display area 11; the third driving circuit 53 in the bend non-display region 212 supplies three third control signals, which may be two scan signals S1 and S2 and one emission control signal EM, or one scan signal S1 and two emission control signals EM1 and EM2, to the pixel circuits in the second bend display region 122.
Also for example, M may not be equal to F (e.g., M is equal to three, and F is equal to four), that is, in one frame of display, the second driving circuit 52 located in the central non-display area 211 provides three second control signals, which may be two scanning signals S1, S2 and one emission control signal EM, for each row of pixel circuits located in the central display area 11; the third driving circuit 53 in the bent non-display region 212 provides four third control signals, which may be two scan signals S1 and S2 and two emission control signals EM1 and EM2, to the pixel circuits in the second bent display region 122.
It should also be understood that the number of the bent non-display areas included in the non-display area of one display panel may be one, or may be multiple, for example, as shown in fig. 6, that is, in the second direction X, the first non-display area on the side of the central display area 11 includes one bent non-display area 212 and the central non-display area 211 in the first direction Y. It is also possible, for example, as shown in fig. 7, that is, in the second direction X, the first non-display area on the side of the central display area 11 includes two bent non-display areas 212 and a central non-display area 211 in the first direction Y. For example, as shown in fig. 3, the first non-display area on one side of the central display area 11 includes two bent non-display areas 212 and a central non-display area 211 in the first direction Y, and the second non-display area on the other side of the central display area 11 also includes two bent non-display areas 212 and a central non-display area 211 in the first direction Y.
When the number of the bent non-display areas included in one display panel is greater than one, at least one first driving circuit 51 may be disposed in both of the two bent non-display areas located at two sides of the display area in the second direction X, or one of the two bent non-display areas may be disposed with at least one first driving circuit 51, and the other one is not disposed with the first driving circuit 51; the number of the first driving circuits 51 arranged in the two non-bending display areas can be equal, so that the width of the two non-bending areas can be reduced simultaneously, and the narrow frame can be realized more favorably.
Along with the development of display technology, display panel is constantly from big change greatly, from thin change thin, from narrow frame to no frame, can never buckle to can buckle, from there being the radian to the four sides is crooked, display panel's edge is crooked promptly, bendable display panel's edge is crooked not only can realize the full-face screen display of front view angle and does not have dead space, the side also can realize showing simultaneously, visual effect has been promoted, do the dysmorphism cutting with four R of display panel, as shown in fig. 8, then buckle four R angles after the dysmorphism cutting through the mode of "folding the carton", form the crooked display panel in four sides, as shown in fig. 9. That is, fig. 9 is a schematic structural diagram of the four-sided curved display panel, and fig. 8 is a schematic structural diagram of the four-sided curved display panel shown in fig. 9 after being unfolded.
As shown in fig. 9, the four-sided curved display screen includes a central display area 11, two third bending display areas 12 oppositely disposed, and two fourth bending display areas 13 oppositely disposed. After the four bent display areas of the four-sided curved display screen shown in fig. 9 are unfolded, as shown in fig. 8, the display panel includes: a display area and a non-display area surrounding the display area, wherein the display area includes: a central display area 11, bending display areas 12 located at both sides of the central display area in a first direction Y, and bending display areas 13 located at both sides of the central display area in a second direction X; the non-display area includes: two first non-display areas 21 located on both sides of the display area in the second direction X, wherein the first non-display areas 21 include in the first direction Y: a central non-display region 211 and two bent non-display regions 212 located at both sides of the central non-display region 211. As shown in fig. 10, the display region includes a plurality of pixels (not shown) arranged in an array and a plurality of scan lines 6 arranged along a first direction Y and extending along a second direction X; the display panel further includes a pixel circuit 3 that drives the pixels to emit light; a plurality of driving circuits are arranged in the non-display area, and the driving circuits transmit scanning signals to the pixel circuits through the scanning lines; the driving circuit comprises at least one first driving circuit 51 arranged in the bending non-display area, and the first driving circuit 51 is used for providing a first control signal for at least one row of pixel circuits in the bending display area 12; and a plurality of second driving circuits 52 disposed in the central non-display area 211, each second driving circuit 52 providing a second control signal to at least one row of pixel circuits located in the central display area 11;
in one frame of display, each row of pixel circuits connected to each first driving circuit 51 receives N first control signals; each row of pixel circuits connected to each second drive circuit 52 receives M second control signals. Wherein M and N are positive integers, and M is greater than N. That is, in one frame of display, the number of control signals output by the first driving circuit 51 in the bent non-display area 212 is less than the number of control signals output by the second driving circuit 52 in the central non-display area 211, and because the number of control signals output by the first driving circuit 51 in the bent non-display area 212 is small, the structure of the first driving circuit 51 is simple, the number of transistors included is small, and the space of the bent non-display area 212 occupied by the first driving circuit 51 is small, so that the width of the bent non-display area 212 is reduced, a narrow frame of the display panel is easily realized, and the display effect is improved.
In an embodiment of the present invention, fig. 11 is an enlarged view of a partial structure of the region B in fig. 10, and as shown in fig. 11, the bending display area 12 includes: a first side edge 121 extending along the first direction Y, a second side edge 122 extending along the second direction X, and a connecting edge connecting the first side edge 121 and the second side edge 122, wherein the connecting edge includes a first connecting edge 123 connected with the first side edge 121, and a second connecting edge 124 connected with the second side edge 122, wherein an angle between the first connecting edge 123 and the second connecting edge 124 is greater than 0 ° and less than 180 °; at least one first driving circuit 51 of the at least one first driving circuit 51 located in the bending non-display area 212 is disposed in the bending non-display area 212 outside the connecting edge, and the at least one first driving circuit 51 is distributed along the edge of the connecting edge.
As for the number of the first driving circuits 51 disposed in the bending non-display area 212, there may be two cases:
in the first case: as shown in fig. 11, the number of the first driving circuits 51 in the bending non-display area 212 is equal to the number of rows of the pixel circuits in the bending display area 12, that is, in one frame of display, each row of the pixel circuits in the bending display area 12 receives N first control signals, and since the number of the control signals output by each first driving circuit 51 in the bending non-display area 212 is small, each first driving circuit 51 has a simple structure and includes a small number of transistors, the space of the bending non-display area 212 occupied by each first driving circuit 51 is small, so that the width of the whole bending non-display area 212 is reduced, a narrow frame of the display panel is easily implemented, and the display effect is improved.
In this case, the first driving circuits 51 in the bending non-display area 212 may be distributed along at least one of the first connecting edge 123 and the second connecting edge 124, and may also be distributed along at least one of the first side edge 121 and the second side edge 122.
In the second case: as shown in fig. 12 to fig. 15, the number of the first driving circuits 51 in the bending non-display area 212 is smaller than the number of rows of the pixel circuits in the bending display area, that is, in one frame of display, the pixel circuits in each row of the bending display area 12 are not connected to the first driving circuits 51 to receive N first control signals, so that the width in the bending non-display area 212 can be properly reduced, and the display quality in the bending display area 12 can be improved.
When the number of the first driving circuits 51 in the bending non-display area 212 is smaller than the number of rows of the pixel circuits in the bending display area 12, that is, at least one first driving circuit 51 and at least one third driving circuit 53 are disposed in the bending non-display area 212, that is, the structure of the at least one row of pixel circuits in the bending display area 12 is different from that of the pixel circuits in other rows, that is, at least one row of first pixel circuits and at least one row of third pixel circuits are disposed in the bending display area 12, wherein the first driving circuit 51 provides N first control signals for the first pixel circuits in each row, and the third driving circuit 53 provides F third control signals for the third pixel circuits in each row, where F and N are positive integers, and F is greater than N. In this case, the number of the first driving circuits 51 and the distribution of the first driving circuits 51 may be as follows:
(1) the bending display area 12 includes a first bending display area 121 close to the central display area and a second bending display area 122 far from the central display area, as shown in fig. 12-14, wherein the length of the first bending display area 121 in the first direction Y is equal to the length of the projection of the connecting edge in the second direction X; the first bending display area 121 includes first pixel circuits (not shown) distributed in an array, and the second bending display area 122 includes second pixel circuits (not shown) distributed in an array; the bending non-display area 212 includes a first bending non-display area and a second bending non-display area, wherein in the second direction X, the first bending non-display area is located at one side of the first bending display area, and the second bending non-display area is located at one side of the second bending display area;
at least one first driving circuit 51 is arranged in the first bending non-display area, and the at least one first driving circuit 51 provides N first control signals for each row of first pixel circuits in the first bending display area 121; at least one third driving circuit 53 is disposed in the second bending non-display area, and the at least one third driving circuit 53 provides F third control signals for each row of second pixel circuits in the second bending display area 122.
Wherein, the at least one first driving circuit 51 located in the first bending non-display area may be distributed along the first connecting edge 123, as shown in fig. 12; or both may be distributed along the second connecting edge 124, as shown in fig. 13; it is also possible that a part of the first driving circuits 51 is distributed along the first connecting edge 123 and a part of the first driving circuits 51 is distributed along the second connecting edge 124, as shown in fig. 14. When the first driving circuits 51 are respectively distributed along the first connecting edge 123 and the second connecting edge 124, the widths of the non-display areas outside the first connecting edge 123 and the second connecting edge 124 can be further reduced, which is further beneficial to realizing a narrow frame design.
It can be understood that the number and distribution of the second bending display areas 122 included in the bending display area may be as shown in fig. 13 and fig. 14, where the bending display area on the same side of the central display area includes two second bending display areas 122, and the two second bending display areas 122 are located on two sides of the first bending display area 121. The bending display area may further include a second bending display area 122, that is, the first bending display area 121 is close to the central display area 11, and the second bending display area 122 is located on a side of the first bending display area 121 far from the central display area 11, as shown in fig. 12.
(2) At least one row of the first pixel circuits and at least one row of the third pixel circuits disposed in the bend display region are irregularly arranged in the column direction, as shown in fig. 14, at this time, the first driving circuit 51 and the third driving circuit 53 are most conveniently distributed according to the wiring.
(3) At least one row of the first pixel circuits 51 and at least one row of the third pixel circuits 53 disposed in the bend display region are arranged at intervals in the column direction, as shown in fig. 15; that is, a row of the first pixel circuits is disposed between two adjacent rows of the second pixel circuits, and at this time, the first driving circuit 51 and the third driving circuit 53 are disposed at an interval in the bending non-display area 212. Because the first pixel circuits and the third pixel circuits are distributed at intervals in the column direction, the width of the bending non-display area 212 is reduced, the display distribution of the bending display area 12 is more uniform, and the display quality is improved.
In the structural diagrams of the four-sided curved display panel after being unfolded, the first driving circuits for transmitting the first control signals to the pixel circuits in the bent display area are all disposed in the bent non-display area on one side of the bent display area. However, since the display panel shown in fig. 8 is a four-sided curved display panel, as shown in fig. 16, the curved display region further includes: a third side 125, wherein the third side 125 is symmetrical to the first side 121 with respect to a middle line of the display area 11 in the first direction Y; a fourth side 126 connected to the other end of the second side 122; the third connecting edge 127 is connected with one end of the third side edge 125 and the fourth connecting edge 128, one end of the fourth connecting edge 128 is connected with the third connecting edge 127, and the other end of the fourth connecting edge 128 is connected with the fourth side edge 126;
in this case, when only one row of pixel circuits in the bent display region receives N first control signals in one frame of display, the first driving circuit 51 for transmitting N first control signals for the row of pixels may be disposed along any one of the third connecting edge 127, the fourth connecting edge 128, the second connecting edge 122, and the first connecting edge 121;
