Detailed Description
The following description will be made in detail with reference to the accompanying drawings for describing an embodiment of an electroluminescent display panel and a display device according to the present invention. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the drawings in the embodiments of the present invention are only provided to illustrate the connection relationship and the relative position between the structures, and do not indicate the size and the area of each structure.
The inventor finds that, as the frame is narrower and narrower, the screen occupation ratio is larger and larger, and in order to ensure that the circuits located in the frame (the frame can be understood as a peripheral area) can provide effective signals for the pixels of the display area, the circuits in the frame need to be effectively arranged and arranged so as to fully utilize the narrower frame; meanwhile, because the frame is narrower and narrower, the space reserved for the circuit in the frame is less and less, and then the vacant space is less and less, so that the water vapor in the air can easily reach the position of the circuit after permeating, the circuit cannot normally work due to damp, and the reliability of the electroluminescent display panel is influenced.
Specifically, as shown in fig. 1, the electroluminescent display panel may include: a first display region a1, a second display region a2, a third display region A3, and a peripheral region B (sparse black-dot filled region), there being one spacing region B0 (dashed box) between the first display region a1 and the second display region a2, and the spacing region B0 belonging to the peripheral region B; the first display region a1, the second display region a2, and the spacing region B0 are located at one side of the third display region A3; among them, the scanning signal generating circuit 1 and the light emission control signal generating circuit 2 are provided in the peripheral region B on the side away from the spacing region B0 near the first display region a1, and similarly, the scanning signal generating circuit 1 and the light emission control signal generating circuit 2 are also provided in the peripheral region B on the side away from the spacing region B0 near the second display region a 2; as shown in fig. 1, since the scanning signal generating circuit 1 and the light-emitting control signal generating circuit 2 are disposed at the same position, the circuit arrangement of the region where the scanning signal generating circuit 1 and the light-emitting control signal generating circuit 2 are located is compact, and the vacant space is small, so that after water vapor permeates, the permeated water vapor can easily erode the scanning signal generating circuit 1 and the light-emitting control signal generating circuit 2 at the position, which causes the abnormal operation of the scanning signal generating circuit 1 and the light-emitting control signal generating circuit 2, and causes the abnormal display of the electroluminescent display panel.
Accordingly, embodiments of the present invention provide an electroluminescent display panel, which is used to optimize the arrangement structures of the scanning signal generating circuit and the light-emitting control signal generating circuit in the peripheral area, so as to effectively improve the reliability of the electroluminescent display panel and effectively solve the problem of electrostatic collection at the position.
Specifically, the electroluminescent display panel provided in the embodiment of the present invention, as shown in fig. 2 to 6, may include: a display region constituted by a first display region a1, a second display region a2, and a third display region A3, and a peripheral region B surrounding the display region; the peripheral region B includes a spacing region B0; the spacing region B0 is located between the first display region a1 and the second display region a 2; and the first display area a1, the second display area a2 and the spacing area B0 are all located at the same side of the third display area A3; wherein the content of the first and second substances,
in a peripheral area B near the first display area a1, a first light emission control signal generation circuit 11 for outputting a light emission control signal, and a first scan signal generation circuit 21 for outputting a scan signal are provided; and the first light emission control signal generating circuit 11 and the first scan signal generating circuit 21 are respectively located near different sides of the first display area a 1;
in the peripheral region B near the second display region a2, there are further provided a second light emission control signal generation circuit 12 for outputting a light emission control signal, and a second scan signal generation circuit 22 for outputting a scan signal; and the second light-emission control signal generating circuit 12 and the second scanning signal generating circuit 22 are respectively located near different sides of the second display area a 2.
In the above-mentioned electroluminescent display panel according to the embodiment of the present invention, the first scan signal generating circuit 21 and the first emission control signal generating circuit 11 located in the peripheral region B are disposed at different sides close to the first display region a1, and the second emission control signal generating circuit 12 and the second scan signal generating circuit 22 are disposed at different sides close to the second display region a2, so as to effectively release the space of the peripheral region B on the side of the first display region a1 away from the partition region B0 and the space of the peripheral region B on the side of the second display region a2 away from the partition region B0, thereby optimizing the circuit arrangement structure of the peripheral region B, and effectively improving the reliability of the peripheral region B on the side of the first display region a1 away from the partition region B0 and the reliability of the peripheral region B on the side of the second display region a2 away from the partition region B0, the normal display of the electroluminescent display panel is ensured.
In practical implementation, when the first light-emitting control signal generating circuit 11 and the first scan signal generating circuit 21 are respectively located near different sides of the first display area a1, in the above electroluminescent display panel provided in the embodiment of the present invention, as shown in fig. 2 to 6, there may be the following situations:
when the first light emission control signal generating circuit 11 is located on the side of the first display area a1 away from the spacing area B0, the first scan signal generating circuit 21 is located on the side of the first display area a1 away from the third display area A3 (as shown in fig. 2); or the first scan signal generating circuit 21 is located in the spacing region B0 and near one side of the first display region a1 (as shown in fig. 3); or the like, or, alternatively,
when the first scan signal generating circuit 21 is located on the side of the first display region a1 away from the spacing region B0, the first light emission control signal generating circuit 11 is located on the side of the first display region a1 away from the third display region A3 (as shown in fig. 4 and 6); or the first light emission control signal generating circuit 11 is located in the spaced area B0 and near one side of the first display area a1 (as shown in fig. 5).
By arranging the positions of the first scanning signal generating circuit 21 and the first light-emitting control signal generating circuit 11, space congestion caused when the first scanning signal generating circuit 21 and the first light-emitting control signal generating circuit 11 are both located in the peripheral area B on the side close to the first display area a1 can be avoided, and a vacant space at the position is increased, so that the circuit is effectively prevented from being eroded by penetrating water vapor, and the reliability of the electroluminescent display panel is improved.
Of course, when the second light-emitting control signal generating circuit 12 and the second scanning signal generating circuit 22 are respectively located near different sides of the second display area a2, an arrangement similar to the first scanning signal generating circuit 21 and the first light-emitting control signal generating circuit 11 may also be adopted, so that, in the above-mentioned electroluminescent display panel provided in the embodiment of the present invention, as shown in fig. 2 to 6, there may be the following cases:
when the second light emission control signal generating circuit 12 is located at a side of the second display region a2 away from the spacing region B0, the second scan signal generating circuit 22 is located at a side of the second display region a2 away from the third display region A3 (as shown in fig. 2 and 6); or the second scan signal generating circuit 22 is located in the spacing region B0 and near one side of the second display region a2 (as shown in fig. 3); or the like, or, alternatively,
when the second scan signal generating circuit 22 is located at a side of the second display region a2 away from the spacing region B0, the second light emission control signal generating circuit 12 is located at a side of the second display region a2 away from the third display region A3 (as shown in fig. 4); or the second light-emission control signal generating circuit 12 is located in the spacing region B0 and near one side of the second display region a2 (as shown in fig. 5).
By arranging the positions of the second scanning signal generating circuit 22 and the second light-emitting control signal generating circuit 12, space congestion caused by the fact that the second scanning signal generating circuit 22 and the second light-emitting control signal generating circuit 12 are both located in the peripheral area B on the side close to the second display area a2 can be avoided, and the free space at the position is increased, so that the circuit is effectively prevented from being eroded by permeated water vapor, and the reliability of the electroluminescent display panel is further improved.
Of course, when the positions of the first scan signal generating circuit 21 and the first light emission control signal generating circuit 11 and the positions of the second scan signal generating circuit 22 and the second light emission control signal generating circuit 12 are provided, in order to reduce the difficulty of manufacturing, it is preferable that the relative positions of the first scan signal generating circuit 21 and the first light emission control signal generating circuit 11 be the same as the relative positions of the second scan signal generating circuit 22 and the second light emission control signal generating circuit 12, as shown in fig. 2 to 5, in order to reduce the difficulty of manufacturing and improve the yield.
In specific implementation, for convenience of explanation, as shown in fig. 2 to 6, in the embodiment of the present invention, an area close to the first display area a1 on the side far from the partition area B0 is referred to as an m1 area, and an area close to the second display area a2 on the side far from the partition area B0 is referred to as an m2 area, so that when the first emission control signal generation circuit 11 is located on the side of the first display area a1 far from the partition area B0 and the second emission control signal generation circuit 12 is located on the side of the second display area a2 far from the partition area B0, that is, the first emission control signal generation circuit 11 is located in the m1 area, and the second emission control signal generation circuit 12 is located in the m2 area, as shown in fig. 2 and 3, in the above-mentioned electroluminescent display panel provided in the embodiment of the present invention, as shown in fig. 7 and 8, the first emission control signal generation circuit 11 and/or the second emission control signal generation circuit 12 project a positive a onto the electroluminescent display panel with a positive a (ii) a The area of each orthographic projection a is the same.
Specifically, in order to be able to release the space of the m1 region and the m2 region to a large extent, in the above-described electroluminescent display panel provided by the embodiment of the present invention, as shown in fig. 7 and 8, the aspect ratio of the front projection a gradually increases along the direction pointing from the first display region a1 to the third display region A3.
Taking the m1 area as an example, as shown in fig. 7 and 8, only a partial structure is shown, wherein, since the border is narrower and narrower, the corners of the border are generally set to be rounded (as shown in fig. 2 to 6), so that in the first display area a1, the number of pixel units in two adjacent rows is different, so that the edge of the first display area a1 on the side away from the spacing area B0 is jagged, as shown in fig. 7 and 8; therefore, with this structure, the aspect ratio of the orthographic projection a of the first light emission control signal generating circuit 11 located in the region m1 can be set to gradually increase from top to bottom, that is, gradually increase along the direction from the first display region a1 to the third display region A3, and the space at the edge round can be greatly released, so that the adverse effect of the permeated water vapor on the first light emission control signal generating circuit 11 in the region m1 can be more effectively avoided, and the reliability of the circuit can be improved. Of course, in the region of m2, the setting of the aspect ratio of the forward projection of the second light emission control signal generation circuit 12 may be the same as that of the first light emission control signal generation circuit 11, and the repeated description is omitted.
It should be noted that, only the area of the orthogonal projection a of the first emission control signal generating circuit 11 in the m1 region may be transversely compressed, only the area of the orthogonal projection a of the second emission control signal generating circuit 12 in the m2 region may be transversely compressed, or both the area of the orthogonal projection a of the first emission control signal generating circuit 11 in the m1 region and the area of the orthogonal projection a of the second emission control signal generating circuit 12 in the m2 region may be transversely compressed, so as to effectively ensure the reliability of the electroluminescent display panel.
Of course, the configuration shown in fig. 7 and 8 is a case where the area of the orthographic projection a of the first emission control signal generation circuit 11 is compressed in the lateral direction, but the configuration is not limited to this, and when the first scan signal generation circuit 21 is located in the region m1, the area of the orthographic projection of the first scan signal generation circuit 21 may be compressed in the lateral direction.
In specific implementation, by the structural arrangement of the circuits of the m1 area and the m2 area, after the space of the two areas is released more, the released space can be utilized to solve the problem of electrostatic charge accumulation at the edge position of the electroluminescent display panel; specifically, in the above-described electroluminescent display panel provided by the embodiment of the present invention, as shown in fig. 7 and 8, in the first display region a1 and/or the second display region a2, there are further provided data lines 30 extending in a direction perpendicular to the arrangement direction of the first display region a1 and the second display region a 2; an electrostatic protection circuit 40 provided in correspondence with the data line 30 is further provided in a peripheral region B near the first display region a1 and/or the second display region a 2; the number of the electrostatic protection circuits 40 is not more than the number of the data lines 30. Through the arrangement of the electrostatic protection circuit 40, the problem that the data line 30 is damaged due to electrostatic breakdown caused by the discharge of electrostatic charges on the data line 30 can be effectively solved, and the data line 30 can effectively transmit data signals to the first display area a1 and/or the second display area a2, so that normal display of a picture is realized.
Specifically, in the above-mentioned electroluminescent display panel provided by the embodiment of the present invention, as shown in fig. 7 and 8, at least a part of the electrostatic protection circuit 40 is disposed on a side of the first display region a1 and/or the second display region a2 away from the spacing region B0.
As shown in fig. 7, only a part of the structures are shown, the number of the electrostatic protection circuits 40 may be equal to the number of the data lines 30, that is, one end of each data line 30 is provided with the electrostatic protection circuit 40 for dispersing the electrostatic charges accumulated on the data line 30; at this time, the esd protection circuits 40 corresponding to the data lines 30 electrically connected to the pixel cells corresponding to the m1 area may be disposed in the m1 area, that is, a portion of the esd protection circuits 40 may be disposed in the released space, and the rest of the esd protection circuits 40 may be disposed in the peripheral area B (denoted as the n1 area) of the first display area a1 on the side far from the third display area A3.
Further, in order to eliminate static charges that easily accumulate in the vicinity of the m1 region and to reduce the footprint of the peripheral region B, the electrostatic protection circuits 40 may be provided only to the data lines 30 that are electrically connected to the pixel cells corresponding to the m1 region, as shown in fig. 8, and therefore, the number of the electrostatic protection circuits 40 provided is smaller than the number of the data lines 30 provided; in this case, all the electrostatic discharge protection circuits 40 may be disposed in the m1 region.
Of course, the data lines 30 in the first display area a1 are only used as an example for illustration, and the arrangement positions and the arrangement number of the data lines 30 in the second display area a2 and the electrostatic protection circuits 40 arranged corresponding to the data lines 30 in the second display area a2 can refer to the specific structures of the data lines 30 in the first display area a1 and the electrostatic protection circuits 40 arranged corresponding to the data lines 30 in the first display area a1, and repeated descriptions are omitted.
In specific implementation, the above-mentioned setting may be performed only on the esd protection circuit 40 corresponding to the data line 30 in the first display area a1, or only on the esd protection circuit 40 corresponding to the data line 30 in the second display area a2, or both the esd protection circuit 40 corresponding to the data line 30 in the first display area a1 and the esd protection circuit 40 corresponding to the data line 30 in the second display area a2, so as to sufficiently disperse the electrostatic charges accumulated on the data line 30, avoid damage to the data line 30 due to electrostatic breakdown, and ensure normal transmission of data signals on the data line 30.
In practical implementation, in the above-mentioned electroluminescent display panel provided by the embodiment of the present invention, as shown in fig. 2 to 6, in the peripheral area B near the third display area a3, a third light emission control signal generation circuit 13 for outputting a light emission control signal and a third scan signal generation circuit 23 for outputting a scan signal are further provided.
Specifically, the third light emission control signal generating circuit 13 and the third scanning signal generating circuit 23 may be located at one side of the third display area a3, as shown in fig. 5; of course, in order to reduce the occupied area of the peripheral region B of the electroluminescent display panel, the third light-emitting control signal generating circuit 13 and the third scanning signal generating circuit 23 are respectively located at opposite sides of the third display region a3, as shown in fig. 2 to 4 and fig. 6, so as to avoid that the occupied area of the peripheral region B at one side is larger and the peripheral region B at the other side is not occupied, which results in unreasonable space utilization of the peripheral region B and is not favorable for the design of the narrow frame.
Specifically, regardless of whether the first light emission control signal generation circuit 11, the second light emission control signal generation circuit 12, or the third light emission control signal generation circuit 13 is used to output the light emission control signal, in the above-described electroluminescence display panel provided in the embodiment of the present invention, the first light emission control signal generation circuit 11, the second light emission control signal generation circuit 12, and the third light emission control signal generation circuit 13 have the same structure and are used to output the light emission control signal; similarly, the first scanning signal generating circuit 21, the second scanning signal generating circuit 22, and the third scanning signal generating circuit 23 have the same configuration, and output scanning signals.
In a specific implementation, in order to input the light emission control signal output by each light emission control signal generation circuit to the corresponding display region, a corresponding light emission control signal line needs to be provided in each display region, and similarly, a corresponding scanning signal line needs to be provided in each display region; therefore, in the above-described electroluminescence display panel provided by the embodiment of the present invention, as shown in fig. 2 to 6, within the first display area a1, the first light emission control signal line 51 and the first scan signal line 61 extending along the arrangement direction of the first display area a1 and the second display area a2 are provided; the first light emission control signal line 51 is provided corresponding to and electrically connected to the first light emission control signal generation circuit 11; the first scanning signal line 61 is provided corresponding to and electrically connected to the first scanning signal generating circuit 21;
in the second display region a2, a second light emission control signal line 52 provided in parallel with the first light emission control signal line 51, and a second scanning signal line 62 provided in parallel with the first scanning signal line 61 are provided; the second light emission control signal line 52 is disposed corresponding to and electrically connected to the second light emission control signal generation circuit 12; the second scanning signal line 62 is provided corresponding to and electrically connected to the second scanning signal generating circuit 22;
in the third display area a3, the third light emission control signal line 53 disposed in parallel with the first light emission control signal line 51, and the third scanning signal line 63 disposed in parallel with the first scanning signal line 61 are provided; the third light emission control signal line 53 is provided corresponding to and electrically connected to the third light emission control signal generation circuit 13; the third scanning signal line 63 is provided corresponding to and electrically connected to the third scanning signal generating circuit 23.
