An embodiment of the present invention provides a display panel, as shown in fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of the display panel provided in the embodiment of the present invention, and fig. 2 is a schematic partial enlarged diagram of a region a in fig. 1, where the display panel includes a high-light-transmission region 1, a frame region 2 surrounding the high-light-transmission region 1, and a display region 3 surrounding the frame region 2. Wherein, be equipped with two at least electrostatic protection structures 4 in the frame region 2, two at least electrostatic protection structures 4 are arranged around high light-transmitting area 1, and electrostatic protection structure 4 walks 5 electricity with the electrostatic discharge and is connected.
The high light transmission region 1 is a region of the display panel having a high light transmittance, and the light transmittance of the region is higher than that of the display region 3. For example, the high light transmission area 1 is used for correspondingly arranging a camera component or an earphone component, and the display panel is transparent but not cut at the high light transmission area 1, or the display panel is cut at the high light transmission area 1, so that a through hole is formed at the high light transmission area 1.
In the display panel provided by the embodiment of the invention, at least two electrostatic protection structures 4 are arranged in the frame region 2, and the electrostatic protection structures 4 are arranged around the high-light-transmission region 1, so that on one hand, the electrostatic protection structures 4 can carry out all-around electrostatic protection on the high-light-transmission region 1, electrostatic charges entering through each region in the high-light-transmission region 1 can be guided away through the electrostatic discharge wiring 5, and the electrostatic protection capability of the display panel is improved; on the other hand, if the esd protection structure 4 is a continuous ring-shaped structure, for the region in the high light transmittance region 1 and the region far away from the connection between the esd protection structure 4 and the esd trace 5, the electrostatic charge entering through the region needs to be transported a long distance in the esd protection structure 4 to be conducted away through the esd trace 5, which increases the accumulation time of the electrostatic charge in the esd protection structure 4, thereby increasing the possibility of the electrostatic charge entering the display region 3; and through setting up static protective structure 4 by stage, the static charge that gets into through different regions in high light-transmitting region 1 all can be through rather than transmitting to static electricity release and walk line 5 apart from nearest static protective structure 4, and then walks away through static electricity release and walk line 5 to avoid the accumulation of static charge in static protective structure 4, shortened the time of leading away of static charge, reduced the possibility that static charge gets into display area 3.
Therefore, by adopting the display panel provided by the embodiment of the invention, the electrostatic protection structure 4 is arranged, so that the all-around electrostatic protection can be performed on the high-light-transmission area 1, the electrostatic charge entering each area of the high-light-transmission area 1 can be guided away by the electrostatic discharge wiring 5, the accumulation of the electrostatic charge in the electrostatic protection structure 4 can be avoided, the static charge guiding away time is shortened, the possibility of the electrostatic charge entering the display area 3 is reduced, and the stability of the display panel is further improved.
As shown in fig. 3, fig. 3 is another structural schematic diagram of the display panel according to the embodiment of the present invention, the display panel further includes a non-display area 6 surrounding the display area 3, the esd trace 5 includes a ground signal line GND and a fixed voltage signal line PVDD, wherein the ground signal line GND is disposed in the non-display area 6, the fixed voltage signal line PVDD is disposed in the display area 3, and the esd protection structure 4 is electrically connected to the ground signal line GND or the fixed voltage signal line PVDD.
The fixed voltage signal line PVDD is a signal line for supplying a power supply voltage signal to the pixel circuit in the display panel. The fixed voltage signal lines PVDD in the display panel may be in a grid structure, that is, the fixed voltage signal lines PVDD include a first fixed voltage signal line PVDD1 extending along the row direction and a second fixed voltage signal line PVDD2 extending along the column direction, and at this time, the electrical connection between the electrostatic protection structure 4 and the fixed voltage signal line PVDD may specifically refer to the electrical connection between the electrostatic protection structure 4 and the first fixed voltage signal line PVDD1 or the electrical connection between the electrostatic protection structure 4 and the second fixed voltage signal line PVDD 2.
Because the ground signal line GND and the fixed voltage signal line PVDD are both electrically connected with the driving chip, therefore, the electrostatic protection structure 4 is electrically connected with the ground signal line GND or the fixed voltage signal line PVDD, the electrostatic charges entering through the high light-transmitting area 1 can be transmitted to the driving chip through the ground signal line GND or the fixed voltage signal line PVDD which are electrically connected with the electrostatic protection structure 4, and then transmitted to the circuit board, and then flow into the human body through the shell of the display panel, and then flow into the ground through the human body, thereby avoiding the electrostatic charges from entering the display area 3, and improving the electrostatic protection capability of the display panel.
Alternatively, as shown in fig. 4, fig. 4 is a schematic diagram illustrating a connection relationship between the esd protection structure and the esd trace according to the embodiment of the present invention, and all the esd protection structures 4 may be electrically connected to the ground signal line GND, respectively. In this arrangement, the static charges entering through the high light-transmitting area 1 can all be discharged through the ground signal line GND, and the static charges are prevented from entering the display area 3. Moreover, based on the connection mode, all the electrostatic protection structures 4 are only electrically connected with one electrostatic discharge wire 5, and in the process, after the grounding signal line GND is formed, all the electrostatic protection structures 4 are only required to be electrically connected with the grounding signal line GND, so that the process is simple and easy to implement.
Optionally, as shown in fig. 5, fig. 5 is a schematic view illustrating another connection relationship between the esd protection structure and the esd trace according to the embodiment of the present invention, and all the esd protection structures 4 may be electrically connected to the fixed voltage signal line PVDD respectively. In this arrangement, the static charges entering through the high light transmission region 1 can be discharged through the fixed voltage signal lines PVDD, and the static charges are prevented from entering the display region 3. Moreover, based on the connection mode, all the electrostatic protection structures 4 are electrically connected with only one type of electrostatic discharge routing 5, and in the process, after the fixed voltage signal line PVDD is formed, all the electrostatic protection structures 4 are electrically connected with the fixed voltage signal line PVDD, so that the process is simple and easy to implement.
Optionally, as shown in fig. 6, fig. 6 is a schematic diagram of another connection relationship between the esd protection structures and the esd traces according to the embodiment of the present invention, where at least one esd protection structure 4 is electrically connected to the ground signal line GND, and at least one esd protection structure 4 is electrically connected to the fixed voltage signal line PVDD. In this arrangement, the electrostatic charges entering through the high light transmission region 1 can be discharged through the ground signal line GND or the fixed voltage signal line PVDD, and the electrostatic charges are prevented from entering the display region 3. Further, according to this connection method, static charges can be discharged through the ground signal line GND or the fixed voltage signal line PVDD, and compared with a method in which all static charges are discharged only from the same static discharge trace 5, the discharge path of static charges is increased, thereby further reducing the possibility that static charges enter the display region 3.
Alternatively, referring to fig. 3 again, each esd protection structure 4 may be electrically connected to the ground signal line GND or the fixed voltage signal line PVDD closest thereto. For example, when the high light transmission region 1 is close to the non-display region 6 on the upper side, one or more of the electrostatic protection structures 4 may be electrically connected to the ground signal line GND extending in the non-display region 6 on the upper side.
By adopting the connection mode, on one hand, each static protection structure 4 is ensured to be electrically connected with one grounding signal line GND or one fixed voltage signal line PVDD, so that static charges entering each area of the high-light-transmittance area 1 can be guided away through the grounding signal line GND or the fixed voltage signal line PVDD; on the other hand, the electrostatic protection structure 4 is electrically connected with the grounding signal line GND or the fixed voltage signal line PVDD which is closest to the electrostatic protection structure 4, so that the time for transmitting electrostatic charges from the electrostatic protection structure 4 to the electrostatic discharge wiring 5 can be shortened, the conduction of the electrostatic charges is further accelerated, and the possibility of the electrostatic charges entering the display area 3 is further reduced; on the other hand, when the electrostatic protection structure 4 is electrically connected with the ground signal line GND or the fixed voltage signal line PVDD through the signal connection wiring, at least a part of the signal connection wiring is located in the display area 3, and since there are many devices in the display area 3 and the wiring is complicated, the signal connection wiring inevitably overlaps with the wiring in the display area 3, and interferes with the signal transmitted on the wiring; and the electrostatic protection structure 4 is electrically connected with the grounding signal line GND or the fixed voltage signal line PVDD which are closest to the electrostatic protection structure, so that the length of the signal connection wiring can be reduced, the overlapping of the signal connection wiring and the wiring in the display area 3 is reduced, and the interference on the signal transmitted on the wiring is reduced.
Optionally, each electrostatic protection structure 4 is electrically connected to the electrostatic discharge trace 5 through at least one signal connection trace. Specifically, referring to fig. 4 to 6 again, each esd protection structure 4 may be electrically connected to the esd release trace 5 through one signal connection trace 7, or, as shown in fig. 7, fig. 7 is a schematic diagram illustrating another connection relationship between the esd protection structure and the esd release trace according to the embodiment of the present invention, and each esd protection structure 4 may be electrically connected to the esd release trace 5 through two or more signal connection traces 7.
The electrostatic protection structures 4 are electrically connected with the electrostatic discharge wires 5 through the signal connection wire 7, so that each electrostatic protection structure 4 is electrically connected with one electrostatic discharge wire 5, and a conduction path is provided for electrostatic charges entering through each region of the high-light-transmission region 1.
The electrostatic protection structures 4 are electrically connected with the electrostatic discharge wires 5 through two or more signal connection wires 7, so that on one hand, each electrostatic protection structure 4 is ensured to be electrically connected with the electrostatic discharge wires 5, and a conduction path is ensured to be provided for electrostatic charges entering through each region of the high-light-transmittance region 1; on the other hand, when one or more signal connecting wires 7 are broken, the electrostatic protection structure 4 and the electrostatic discharge wire 5 can still be electrically connected through the other unbroken signal connecting wires 7, so that the connection stability of the electrostatic protection structure 4 and the electrostatic discharge wire 5 is improved; on the other hand, the static charges on the same electrostatic protection structure 4 can be transmitted to the static electricity discharge wires 5 through the plurality of signal connection wires 7 at the same time, so that the conduction of the static charges is accelerated, and the possibility of the static charges entering the display area 3 is further reduced.
It should be noted that, when the esd protection structure 4 is electrically connected to the esd releasing trace 5 through the plurality of signal connecting traces 7, the plurality of signal connecting traces 7 may be electrically connected to the same esd releasing trace 5 or different esd releasing traces 5. The number of signal connecting traces 7 electrically connected to different esd protection structures 4 may be the same or different.
As shown in fig. 8 to 10, fig. 8 is another schematic connection relationship diagram of the esd protection structure and the esd trace provided in the embodiment of the present invention, fig. 9 is a sectional view taken along a direction a1-a2 in fig. 8, fig. 10 is a sectional view taken along a direction B1-B2 in fig. 8, a plurality of Gate lines Gate and a plurality of Data lines Data are arranged in the display region 3 in a cross-insulated manner, when the esd protection structure 4 and the esd trace 5 are electrically connected through the signal connection trace 7, the signal connection trace 7 is arranged in a different layer from the Gate lines Gate, and the signal connection trace 7 is arranged in a different layer from the Data lines Data.
The Gate lines Gate are signal lines for Gate scanning signals to the pixel circuits in the display panel, and the Data lines Data are signal lines for supplying Data signals to the pixel circuits in the display panel.
When the electrostatic protection structure 4 is electrically connected with the electrostatic discharge trace 5 through the signal connection trace 7, the signal connection trace 7 needs to penetrate through at least one Gate line Gate or at least one Data line Data, and the signal connection trace 7, the Gate line Gate and the Data line Data are arranged in different layers, so that on one hand, the interference of the signal connection trace 7 on a Gate scanning signal transmitted on the Gate line Gate and a Data signal transmitted on the Data line Data can be reduced; on the other hand, the static charge transmitted on the signal connection wiring 7 can be prevented from entering the Gate line Gate or the Data line Data, and the influence of the static charge on the normal display of the display panel is reduced.
It should be noted that the relative positional relationship between the signal connection trace 7 and the Gate line Gate, the Data line Data, the first fixed voltage signal line PVDD1, and the second fixed voltage signal line PVDD2 shown in fig. 9 and 10 is only a schematic illustration, and does not represent a specific limitation on the position of the film layer of the signal connection trace 7. In practice, the signal connecting trace 7 may be formed by a separate patterning process, and at this time, the signal connecting trace 7 is not in the same layer as any structure in the display panel. Alternatively, the signal connection trace 7 may also be disposed on the same layer as other structures in the display panel except for the Gate line Gate and the Data line Data, for example, the signal connection trace 7 may be on the same layer as the touch signal trace electrically connected to the touch electrode; by adopting the arrangement mode, the signal connection wiring 7 can be formed by adopting the same composition process with other structures in the display panel, thereby reducing the process flow and the manufacturing cost.
In addition, it should be noted that, in other optional embodiments of the present invention, the signal connection trace 7 may also be disposed on the same layer as the Gate line Gate, and only the overlapping position of the signal connection trace 7 and the Gate line Gate needs to be connected by using a bridge-spanning structure. Alternatively, the signal connection trace 7 and the Data line Data may be disposed on the same layer, and only the overlapping position of the signal connection trace 7 and the Data line Data needs to be connected by using a bridge-spanning structure.
As shown in fig. 11, fig. 11 is a schematic structural diagram of an electrostatic protection structure according to an embodiment of the present invention, an end of at least one electrostatic protection structure 4 is provided with a gap shielding structure 8, and a position of the gap shielding structure 8 corresponds to a gap area 9 between two adjacent electrostatic protection structures 4.
It should be noted that, the arrangement position of the gap shielding structure 8 corresponds to the gap area 9 between two adjacent electrostatic protection structures 4, that is, each gap shielding structure 8 is arranged corresponding to the gap area 9 between two adjacent electrostatic protection structures 4, so that the gap shielding structure 8 can shield the gap area 9 between the electrostatic protection structures 4. It should be noted that the gap shielding structure 8 may be located on a side of the electrostatic protection structure 4 facing the high light transmittance region 1, or on a side of the electrostatic protection structure 4 facing away from the high light transmittance region 1, as long as shielding of the gap region 9 is achieved, which is not specifically limited in this embodiment of the present invention. In addition, in order to avoid the need to separately form the gap shielding structure 8 by using an additional process and reduce the process complexity, the gap shielding structure 8 may be integrally formed with the electrostatic protection structure 4.
Specifically, as shown in fig. 12, fig. 12 is a schematic structural diagram of the gap shielding structure according to the embodiment of the present invention, and the gap shielding structure 8 may include a shielding portion 81 and a connecting portion 82, where the shielding portion 81 is located on a side of the gap region 9 facing the display region 3, and the connecting portion 82 is respectively communicated with the shielding portion 81 and the corresponding electrostatic protection structure 4. The electrostatic charge in the gap region 9 is transmitted to the communicating portion 82 and the electrostatic protection structure 4 communicating with the communicating portion 81, and is discharged through the electrostatic discharge trace 5.
Since at least two electrostatic protection structures 4 are arranged in segments, a gap region 9 inevitably exists between two adjacent electrostatic protection structures 4, and static charges may enter the display region 3 through the gap region 9, thereby causing damage to devices in the display region 3. In the embodiment of the present invention, the gap shielding structure 8 is disposed at the end of the esd protection structure 4, and the gap shielding structure 8 is used to shield the gap region 9, so that the electrostatic charge in the gap region 9 enters the corresponding esd protection structure 4 through the gap shielding structure 8, and is further conducted away through the electrostatic discharge trace 5, thereby further reducing the possibility of the electrostatic charge entering the display region 3.
As shown in fig. 13, fig. 13 is another schematic structural diagram of the electrostatic protection structure according to the embodiment of the present invention, the electrostatic protection structure 4 includes a first end portion 10 and a second end portion 11, the first end portions 10 and the second end portions 11 are alternately arranged along a clockwise direction, and the first end portion 10 of each electrostatic protection structure 4 is provided with a gap shielding structure 8, or the second end portion 11 of each electrostatic protection structure 4 is provided with a gap shielding structure 8.
The first end part 10 or the second end part 11 of each electrostatic protection structure 4 is provided with a gap shielding structure 8, so that on one hand, the gap shielding structure 8 is correspondingly arranged in the gap area 9 between every two adjacent electrostatic protection structures 4, thereby further preventing electrostatic charges from entering the display area 3 through the gap structure and further improving the electrostatic protection capability of the display panel; on the other hand, since one end of each esd protection structure 4 is provided with one gap shielding structure 8, the structures of the plurality of esd protection structures 4 are the same for one display panel, and thus, the process complexity in the process of forming the esd protection structures 4 can be reduced.
Alternatively, the electrostatic protection structure 4 may be formed of a metal material or a metal oxide material.
When the electrostatic protection structure 4 is formed by a metal material, based on good conductivity of the metal material, the conduction time of electrostatic charges can be shortened, and the electrostatic protection capability of the display panel is improved. Specifically, the electrostatic protection structure 4 may be formed of a metal material with good conductivity and low cost, such as aluminum, molybdenum, or copper.
When the electrostatic protection structure 4 is formed of a metal oxide material, such as indium tin oxide, indium zinc oxide, or indium gallium zinc oxide, based on the electrical conductivity and good transparency of indium tin oxide, indium zinc oxide, and indium gallium zinc oxide, the visibility of the electrostatic protection structure 4 can be reduced on the premise that the electrostatic charge can be conducted away through the electrostatic protection structure 4, thereby reducing the influence of the electrostatic protection structure 4 on the normal display of the display panel.
Optionally, referring to fig. 11 again, the distance between the electrostatic protection structure 4 and the edge of the high light transmittance region 1 is L, where L satisfies: l is more than or equal to 50 mu m and less than or equal to 200 mu m.
In the manufacturing process of the electrostatic protection structure 4, an alignment deviation inevitably exists, if L is less than 50 μm, the electrostatic protection structure 4 and the high-transmittance region 1 are too close to each other, and then, when the setting position of the electrostatic protection structure 4 caused by the alignment deviation factor deviates from the standard position, the electrostatic protection structure 4 may be located in the high-transmittance region 1, which affects the light transmittance of the high-transmittance region 1, and further affects the normal imaging of the camera component. If L is greater than 200 μm, the distance between the esd structure 4 and the high transmittance region 1 is too far, and the distance between the esd structure 4 and the display region 3 is too close when the width of the frame region 2 is fixed, so that when the setting position of the esd structure 4 is deviated, the esd structure 4 may be located in the display region 3 to block the sub-pixels in the display region 3, thereby affecting the normal light emission of the display region 3.
Therefore, in the embodiment of the present invention, by setting L to be between 50 μm and 200 μm, it is able to avoid the electrostatic protection structure 4 from being too close to the high-transmittance region 1, and avoid the electrostatic protection structure 4 from affecting the transmittance of the high-transmittance region 1, and also avoid the electrostatic protection structure 4 from being too close to the display region 3, and avoid the electrostatic protection structure 4 from affecting the normal light emission of the display region 3.
Optionally, the number of the electrostatic protection structures 4 is N, where N is greater than or equal to 3. Compared with the two electrostatic protection structures 4 arranged in the frame area 2, the three or more electrostatic protection structures 4 are arranged, so that electrostatic charges can be conducted away through the electrostatic protection structures 4 with more quantity, the conducting path of the electrostatic charges is increased, the conducting time of the electrostatic charges in each area is shortened, and the electrostatic protection capability of the display panel is further improved.
Of course, the maximum value of N may be defined according to the actual size of the high light transmission region 1, and the larger the area of the high light transmission region 1 is, the larger the number of the electrostatic protection structures 4 may be.
