Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, the present invention is further described with reference to the accompanying drawings and examples.

It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1, in the prior art, when a display mother board is cut, static electricity may be accumulated in an area of a single display panel 100 ', and static electricity amount in an area of each display panel 100' is different, and if the static electricity amount in the area of some display panels 100 'is too large, a display area AA' in the area of the display panel 100 'may be damaged, resulting in abnormal display of the display panel 100' after cutting. In order to prevent the local static electricity in the display panel 100 'region from being too high, static electricity conducting lines 2' and 3 'are provided in the display mother board to connect the display panel 100' regions and uniformly disperse the static electricity. However, after the display mother board is cut along the cutting line Q ', a part of the remaining static conductive lines 2' connected to the display panel is located in the frame area BB 'of the display panel 100', and is in an exposed state, and static electricity easily enters the display panel 100 'through the static conductive lines 2', and damages the display area, thereby causing display abnormality. The problem of overhigh static electricity quantity is solved by the static conducting wire before the panel is cut, and the static electricity of the display panel is damaged by static electricity after the display panel is cut by one part of the static conducting wire connected to the display panel. Therefore, it is highly desirable to provide a novel display panel structure capable of balancing the electrostatic damage before and after the cutting of the display panel.

In view of the above, the present invention provides a display panel and a display device, which solve the problem that the display panel is easily damaged by electrostatic shock before and after being cut. The following detailed description is provided for specific embodiments of the display panel and the display device according to the present invention.

Referring to fig. 2, fig. 3 and fig. 4, fig. 2 is a schematic plan view of a display panel according to an embodiment of the present invention before being cut, fig. 3 is a schematic plan view of a display panel according to an embodiment of the present invention after being cut, and fig. 4 is a schematic partial enlarged view of fig. 3. The present embodiment provides a display panel 100, including a display area AA and a non-display area BB, wherein the display area AA includes a signal line (not shown), the non-display area BB includes a static-electricity-preventing line 2 and a connection terminal 4, the connection terminal 4 includes a first end 41 and a second end 42, the first end 41 of the connection terminal 4 is electrically connected to the static-electricity-preventing line 4, and the second end 42 is electrically connected to the signal line;

the static resistance wire 4 includes a main body 21 and a branch 22, and the branch 22 is located on a side of the main body 21.

Specifically, the display panel 100 provided in the present embodiment includes a display area AA and a non-display area BB, the display area AA includes a signal line (not shown), the non-display area BB includes a static resistance line 2 and a connection terminal 4, and the signal line and the static resistance line 2 are electrically connected through the connection terminal 4. In addition to the electrostatic preventing line 2 directly connected to the display panel 100, before the display mother board is cut, an electrostatic connecting line 3 is further included between adjacent display panels 100, wherein one end of the electrostatic preventing line 2 is connected to the display area AA of the display panel 100, and the other end is connected to the electrostatic connecting line 3. Before the display mother board is cut, the display panels 100 are connected through the electrostatic connecting lines 3, so that uniform conduction of static electricity is realized, and excessive local static accumulation of a certain display panel is prevented; after the display mother board is cut along the cutting line Q, only the static resistance line 2 is left to be connected with the display panel 100. The design of the branch part 22 is added on the structure of the main body part 21 of the static electricity prevention line 2, and the resistance of the static electricity prevention line 2 can be increased by combining the width change of the main body part 21 and the branch part 22, so that static electricity is prevented from entering the display panel 100, the static electricity damage of a display area after the cutting of a display mother board is avoided, and normal display is realized.

In the present embodiment, the electrostatic preventing line 2 is designed to be an inverted T-shaped structure, and can be divided into a main body portion 21 and branch portions 22, wherein the main body portion 21 extends along a first direction, the first direction is perpendicular to a second direction, and the branch portions 22 are located at the side of the main body portion 21 along the second direction. The width of the main body part 21 in the second direction is narrower than that of the static electricity preventing line in the prior art, so that the resistance of the static electricity preventing line 2 can be increased, and the static electricity blocking effect is realized; meanwhile, the main body part 21 with the branch parts 22 on the side edges is wider in the second direction, so that the risk of breakage of the static resistance static wire 2 due to too thin wires can be avoided. The width and the shape of the static resistance static line 2 in the first direction are changed to have a larger resistance value, so that static electricity entering the display panel 100 after the display motherboard is cut is prevented. In the first direction, the ratio of the length of the branch portion 22 to the total length of the electrostatic discharge prevention line 2 is set according to the specific display panel requirements, i.e. the ratio of the wider width of the electrostatic discharge prevention line 2 (i.e. the portion of the electrostatic discharge prevention line 2 where the branch portion 22 is not disposed at the side of the main body portion 21) to the narrower width (i.e. the portion of the electrostatic discharge prevention line 2 where the branch portion 22 is disposed at the side of the main body portion 21) in the total length of the electrostatic discharge prevention line 2. If the length of the branch portion 22 accounts for too large a proportion of the total length of the static electricity preventing line 2, i.e. the narrower width of the static electricity preventing line 2 accounts for less, the resistance of the static electricity preventing line 2 is increased relatively less, so that the capability of blocking static electricity from entering the display panel 100 is weaker; if the length of the branch 22 is too small in proportion to the total length of the static electricity preventing line 2, that is, the width of the static electricity preventing line 2 is less, the resistance of the static electricity preventing line 2 is increased relatively greatly, which can prevent static electricity from entering the display panel 100, but is not favorable for dissipating static electricity between the display panels 100 before cutting the display motherboard, so the length of the branch 22 in the first direction is determined according to specific conditions.

In this embodiment, fig. 2 only illustrates a connection manner between one display panel 100 and an adjacent display panel 100(1) at the cut front edge of the display motherboard, wherein the display motherboard adopts an arrangement manner that the lower frame of the previous display panel 100 is close to the upper frame of the adjacent next display panel 100 (1). In a specific implementation, the display panels may be connected according to a specific arrangement in the display motherboard, which is not specifically limited in this embodiment.

It should be noted that the static electricity preventing line 2 may be an integrally molded material, and the main body portion 21 and the branch portions 22 shown in fig. 3 are for better explaining the structure and the purpose of the static electricity preventing line 2 at various positions, and it is not meant to technically make the main body portion 21 and then the branch portions 22. Meanwhile, the structures of other static resistance stopping lines in the invention are also integrally formed materials, and are not described in detail below.

It should be noted that some display panels may not have direct connection between the connection terminals in the non-display area and the signal lines in the display area, and some circuit areas may be arranged between the connection terminals and the signal lines. The circuit regions which may be arranged are indicated by blank intervals in the connecting terminals and the display regions in the application, and the specific arrangement of the circuit regions is not specifically limited in the application.

In some alternative embodiments, referring to fig. 3 and fig. 5 in combination, fig. 5 is another partial enlarged structural diagram of fig. 3, the main body portion 21 of the static electricity preventing line 2 includes a first side 21a and a second side 21b, the branch portion 22 includes a plurality of sub-branch portions 221, and the plurality of sub-branch portions 221 are distributed on the first side 21a and the second side 21b of the main body portion 21.

Specifically, the branch portion 22 may be formed of a plurality of sub-branch portions 221 as shown in fig. 5 and distributed on the first side 21a and the second side 21b of the main body portion 21, instead of the single integral structure as shown in fig. 4. Since static electricity may be accumulated inside the individual display panels, when the display mother board is cut, an individual display panel is obtained to block the static electricity from the outside and promote the dissipation of the static electricity generated inside the display panel, and therefore the sub-branch portion 221 is provided in this embodiment. By providing the end portions of the sub-branch portions 221 on both sides of the main body portion, a point discharge structure is formed, which can prevent external static electricity from entering the display panel 100 and promote static electricity dissipation inside the display panel 100.

Meanwhile, by providing a plurality of sub-branch portions 221 corresponding to a plurality of large resistor structures connected in series, not only the length (i.e., the length of the sub-branch portion 221 in the first direction) and the width (i.e., the width of the sub-branch portion 221 in the second direction) of each sub-branch portion 221 can be precisely controlled, but also the interval 5 between adjacent sub-branch portions distributed on the same side on one electrostatic prevention line can be controlled, the obtained electrostatic prevention line resembles a ruler, and how much resistance each grid (i.e., the sum of the length of one sub-branch portion 221 and the length of the adjacent interval 5 in the first direction) has can be calculated. The balance of electrostatic blocking and dissipation in the individual display panels 100 can be achieved by controlling the cutting-out of a specific number of the sub-branch sections 221 on the electrostatic preventing lines when the display mother panel is cut. For example, after one sub-branch 221 structure is cut off during panel cutting, subsequent monitoring finds that the remaining static resistance stop line 2 has a large resistance value, although static electricity can be blocked from entering the display panel 100, static electricity dissipation in the display panel 100 is not easily promoted, so that one or more sub-branch 221 structures can be continuously cut off according to specific process requirements, an optimal cutting position in the scale structures of the sub-branch 221 can be obtained through the process, accurate cutting is conveniently achieved during next cutting, process fluctuation is prevented, and cutting accuracy and efficiency are improved.

In some alternative embodiments, referring to fig. 3 and fig. 5 in combination, the extension direction of the static resistance line 2 is a first direction, the first direction is perpendicular to a second direction, and the widths d of the plurality of sub-branch portions 221 in the second direction are all equal.

Specifically, the widths d of the sub-branch portions 221 in the second direction are all equal, so that a regular electrostatic prevention line 2 structure can be obtained, which is beneficial to process preparation, and the resistance value distribution on the electrostatic prevention line is uniformly changed, which is beneficial to calculating the cutting position during cutting, realizing accurate cutting, preventing process fluctuation, and improving cutting precision and efficiency.

In some alternative embodiments, please refer to fig. 3 and 5 in combination, the sub-branch portions 221 of the first side 21a and the second side 21b of the static electricity prevention line 2 are symmetrically distributed along the main body portion 21.

Specifically, the sub-branch portions 221 in the static electricity prevention line 2 are distributed on both sides of the main body portion 21, i.e., the first side 21a and the second side 21b, and are symmetrically distributed along the central axis O of the main body portion 21, so that the width of the static electricity prevention line where the sub-branch portions 22 are distributed on the side of the main body portion 21 is wide, and the risk of breaking the static electricity prevention line 21 can be avoided. In the embodiment, a regular structure of the electrostatic prevention line 2 can be obtained, which is beneficial to process preparation, and the resistance distribution of the electrostatic prevention line 2 is uniformly changed, so that the cutting position can be calculated during cutting, accurate cutting is realized, process fluctuation is prevented, and the cutting precision and efficiency are improved.

In some alternative embodiments, referring to fig. 3 and fig. 6 in combination, fig. 6 is another partial enlarged structural diagram of fig. 3, and the sub-branch portions 221 of the first side 21a and the second side 21b of the electrostatic stopping line 2 are asymmetrically distributed along the main body portion 21.

Specifically, the sub-branch portions 221 of the static resistance static lines 2 are distributed on two sides of the main body 21, i.e., the first side 21a and the second side 21b, and are asymmetrically distributed along the central axis O of the main body 21, so as to avoid the problem that the sub-branch portions 21 contact with each other to cause short circuit when the distance between two adjacent static resistance static lines 2 is short. Taking the first sub-branch 2211 and the second sub-branch 2212 in fig. 6 as an example, the sub-branch 221 on the static resistance line 2 is asymmetrically distributed along the central axis of the main body 21, and the perpendicular projection of the first sub-branch 2211 and the second sub-branch 2212 on the first plane, which is perpendicular to the display panel and parallel to the first direction, only partially overlaps or does not overlap, so as to avoid the short circuit problem caused by too wide width of the sub-branch 221 in the second direction or too narrow distance between adjacent static resistance lines 2.

In some alternative embodiments, please refer to fig. 3 and fig. 7 in combination, fig. 7 is another schematic diagram of a partial enlarged structure of fig. 3, and widths d of at least two sub-branch portions 221 in the static resistance static line 2 in the second direction are not equal.

Specifically, when the widths of the sub-branch portions 221 in the first direction are equal, the resistance value calculation and the process of the static resistance line 2 are facilitated, and the sub-branch portions 221 having different widths may be designed. When the width of the sub-branch portions 221 is different, the sub-branch portions 221 may be designed to be asymmetrically distributed along the central axis O of the main body portion 21, and the width of the sub-branch portions 221 may be designed according to the pitch of the adjacent static resistance lines 2. Taking the sub-branch portions with the widths d1 and d2 in the second direction as an example, the sub-branch portion with the width d1 may be set to have a width longer than the width of other sub-branch portions on the same static resistance line 2, as long as d1 is ensured not to contact with the static resistance line to which d2 belongs, a certain distance is kept, and short circuit is prevented. By designing the sub-branch portions 221 to have different lengths, the electrostatic prevention line 2 having the extra-long sub-branch portion 221 can be formed, and then by calculating the resistance value, the electrostatic prevention line 2 having a shorter length in the first direction can be obtained while ensuring that the display panel has certain electrostatic blocking and electrostatic dissipation capabilities. The length of the static resistance line 2 in the first direction is related to the size of the frame of the display panel, so that the length of the static resistance line 2 in the first direction is reduced, which is beneficial to realizing the narrow frame design of the display panel.

Meanwhile, in the present embodiment, how much resistance each cell (i.e., the sum of the length of one sub-branch portion 221 and the length of the adjacent space 5 in the first direction) has can be calculated. The balance of electrostatic blocking and dissipation in the individual display panels 100 can be achieved by controlling the cutting-out of a specific number of the sub-branch sections 221 on the electrostatic preventing lines when the display mother panel is cut. In addition, the optimum cutting position in the static electricity prevention wire 2 having the plurality of sub-branch portions 221 can be obtained through process verification, accurate cutting is realized, process fluctuation is prevented, and cutting accuracy and efficiency are improved.

It should be noted that the width of the sub-branch portion 221 of the electrostatic stopping line 2 in the first direction shown in fig. 7 is only an illustration, and the design may be performed according to actual process requirements, and the present invention is not limited thereto.

In some alternative embodiments, please refer to fig. 3 and fig. 8 in combination, fig. 8 is another schematic diagram of a partial enlarged structure of fig. 2, and a first space 51 is formed between adjacent sub-branch portions 221 on the same side of a static resistance static line 2;

the static resistance stop line 2 comprises a first static resistance stop line 2a and a second static resistance stop line 2b, the sub-branch part of the first static resistance stop line 2a close to one side of the second static resistance stop line 2b is vertically projected on a first plane, and a first interval falling on one side of the second static resistance stop line 2b close to the first static resistance stop line 2a is vertically projected on the first plane;

the first plane is perpendicular to the plane of the display panel and parallel to the first direction.

Specifically, in fig. 8, a first interval 51 in which a sub-branch portion having a width d1 in the second direction is located in a sub-branch portion on the side of the first static-resistance wire 2a closer to the second static-resistance wire 2b and the second static-resistance wire 2b closer to the first static-resistance wire 2a will be described as an example. Since the sub-branch portion with the width d1 has the length L1 in the first direction, the length G1 of the first space 51 in the first direction, and the projection of the two on the first plane satisfies that L1 is smaller than G1, and the sub-branch portion with the width d1 falls within the projection of the first space 51, in this case, on the premise that the sub-branch portion with the width d1 does not contact with the second static resistance line 2b, the width of the sub-branch portion with the width d1 in the second direction can be made larger, the static electricity preventing line 2 with the extra-long sub-branch portion 221 can be made, and further, by calculating the resistance value, the static electricity preventing line 2 with the shorter length in the first direction can be obtained on the premise that the display panel has certain static electricity blocking and static electricity dissipating capabilities. The length of the static resistance line 2 in the first direction is related to the size of the frame of the display panel, so that the length of the static resistance line 2 in the first direction is reduced, which is beneficial to realizing the narrow frame design of the display panel.

It should be noted that the sub-branch portion with the width d1 and the first space 51 are only examples in this embodiment, and the sub-branch portion and the first space at other positions in the display panel may be set to satisfy the requirement that the perpendicular projection of the sub-branch portion on the side of the first electrostatic stopping line close to the second electrostatic stopping line on the first plane falls within the perpendicular projection of the first space on the side of the second electrostatic stopping line close to the first electrostatic stopping line on the first plane. The present invention is not particularly limited in this regard.

In some alternative embodiments, please refer to fig. 3 and 9 in combination, fig. 9 is another schematic diagram of a partial enlarged structure of fig. 3, and at least two sub-branch portions 221 of the static resistance line 2 are irregular.

Specifically, the plurality of sub-branch portions 221 in the branch portion 22 may be arranged in an irregular pattern, in addition to the common rectangular pattern. In the specific design process, it is difficult to control the manufacturing conditions to obtain a regular pattern structure, such as a rectangle, so that the sub-branch portion 221 may be obtained as an irregular pattern with an arc-shaped edge. However, as long as the sub-branch portion 221 has a certain width in the second direction, the effect of promoting the dissipation of static electricity in the individual display panel can be achieved; and in the process of electrostatic discharge, the structure with the arc or tip edge is easier to discharge the electrostatic, so the structure of the branch sub-portion 221 is designed to be irregular, and the requirements for electrostatic obstruction and dissipation in the display panel can be balanced.

It should be noted that the shape of the sub-branch portion 221 of the static resistance line 2 shown in fig. 9 is merely an illustration, and in the specific implementation, the shape may be designed according to the actual situation as long as the sub-branch portion 221 has a certain width in the second direction, and the present invention is not limited to this.

In some alternative embodiments, please refer to fig. 10a and 10b, fig. 10a is another enlarged partial structure diagram of fig. 3, and fig. 10b is a structure diagram of a display panel in the prior art. The display panel further includes an FPC5(Flexible Printed Circuit), and the FPC5 includes FPC signal terminals 51 and an IC6(Integrated Circuit), in which the FPC signal terminals 5 are connected to the connection terminals 4.

Specifically, the IC6 is bound to the FPC5, and the FPC signal terminal 51 is connected to the connection terminal 4 to supply signals to the display panel. As shown in fig. 10b, in the conventional cog (chip on glass) structure, when the IC6 'and the FPC 5' are separately connected to the display area AA 'of the display panel through different terminals, there are some disconnection structures in the IC 6', so that when static electricity on the static electricity blocking line passes through the FPC5 'and then passes through the IC 6', a part of static electricity can be blocked from entering the display area AA 'due to the disconnection structures in the IC 6', and the probability of damage to the display panel by the static electricity is reduced. However, as shown in fig. 10a, in the cof (chip on FPC) structure, when the IC6 is bonded to the corresponding FPC5 and the entire structure is connected to the display area AA of the display panel, static electricity on the static electricity blocking line is not blocked when entering the signal line through the connection terminal, so that the display panel is easily damaged by the static electricity. Therefore, for the display panel with the COF structure, the electrostatic resistance static line is structurally designed, so that the probability of electrostatic damage of the display panel can be effectively reduced.

It should be noted that, in this embodiment, only the design in the invention is described to have a better improvement effect on a COF type display panel, but the invention is not limited to be applied only to a COF type display panel, and may also be applied to other types of display panels, and the invention is not limited to this.

It should be noted that, in this example, only the non-display region structures of the COG type and COF type display panels are roughly listed, the problems to be solved in the present application are described, and in the implementation, a more detailed structure may be further provided in the non-display region of the display panel, which is not specifically limited in this application.

In some alternative embodiments, the static-electricity-blocking line is made of a semiconductor material.

Specifically, the resistance value of the static resistance static line is related to the ability to transmit static electricity. Before the display mother board is cut, the static resistance stop line is connected with each display panel to be cut, so that static electricity among the display panels to be cut is promoted to be dredged, local static electricity accumulation is prevented, static electricity is prevented from being damaged, and the resistance value of the static resistance stop line cannot be too large. After the display mother board is cut, the static electricity preventing line prevents external static electricity from entering the independent display panel, so the resistance value cannot be too small. Common materials include metal, nonmetal and semiconductor, and the metal has small resistance value and is not beneficial to preventing static electricity from entering the display panel; the nonmetal is small in resistance value and not beneficial to leading out static electricity in the display panel, so that the static electricity problem before and after the display panel is cut is comprehensively considered, the semiconductor material is selected to manufacture the static resistance stop line in the embodiment, and meanwhile, the conduction of the static electricity before cutting and the separation of the static electricity after cutting are realized, so that normal display is realized.

It should be noted that, since the semiconductor is a common material with a relatively moderate resistance, the electrostatic discharge prevention line in this embodiment is made of a semiconductor material. In addition, the static resistance stop line may also be made of other materials with moderate resistance, as long as the static problem before and after the cutting of the display panel can be balanced, which is not limited in the present invention.

In some alternative embodiments, the display area AA of the display panel includes an active layer (not shown), and the static resistance line and the active layer are disposed using the same material.

Specifically, the display area AA of the display panel includes an active layer, and the active layer is generally formed using a semiconductor, so that the static electricity preventing line and the active layer may be formed using the same material, thereby simplifying the process materials and facilitating the process.

In some alternative embodiments, please refer to fig. 2 and fig. 11, fig. 11 is a partial enlarged view of the display panel cutting position in fig. 2, the display panel 100 includes a cut-and-remain region S and a cut-and-remove region R during cutting, and the static electricity preventing line 2 of the cut-and-remain region R includes a branch portion 22.

Specifically, when the motherboard is cut, the motherboard is cut along the cutting line Q on the electrostatic preventing line 2, wherein the length of the electrostatic preventing line 2 remaining after cutting in the first direction determines the resistance thereof, and the electrostatic preventing line has the capability of blocking and promoting electrostatic dissipation. In order to ensure the independent display panel 100 has the electrostatic blocking capability, the electrostatic blocking line 2 of the cut and reserve region R cannot be too short when cutting. In order to ensure that the independent display panel 100 has the static electricity dissipation capability, the static electricity prevention line 2 of the cut and reserve region R should retain the branch portion 22 structure, so that the remaining static electricity prevention line 2 in the display panel 100 after cutting has a portion with a narrower width in the second direction, which can block external static electricity from entering the display panel 100, and at the same time, has a portion with a wider width in the second direction, which can promote the dissipation of static electricity accumulated in the display panel 100. Further, if the cutting retention region has a plurality of sub-branch sub-portions 221 structure, the speed of static electricity dissipation can be further increased.

It should be noted that the cutting position Q shown in fig. 11 is only an illustration, and in the specific implementation, as long as the static resistance line 2 has the branch portion 22 structure in the cutting retention region R, the specific cutting position Q may be designed according to the actual situation, and the invention is not limited to this.

In some alternative embodiments, please refer to fig. 12, where fig. 12 is a schematic plan view illustrating a display device according to an embodiment of the present invention, and the display device 200 provided in this embodiment includes the display panel 100 provided in the above embodiment of the present invention. The embodiment of fig. 12 is only an example of a mobile phone, and the display device 200 is described, it is understood that the display device 200 provided in the embodiment of the present invention may be another display device 200 having a display function, such as a computer, a television, and a vehicle-mounted display device, and the present invention is not limited thereto.
