It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1 and fig. 2 in combination, the present invention provides a display panel, including: the touch control device comprises a touch control electrode layer 10, a touch control line layer 20 and an insulating layer 30, wherein the insulating layer 30 is arranged between the touch control electrode layer 10 and the touch control line layer 20; the touch electrode layer 10 includes a plurality of touch electrodes 11, and the plurality of touch electrodes 11 are arranged in an array along a first direction x and a second direction y; wherein the first direction x and the second direction y intersect; the touch line layer 20 includes a plurality of touch lines 21, and the plurality of touch lines 21 extend along the second direction y;
the insulating layer 30 includes a plurality of first openings 31 and a plurality of second openings 32, the first openings 31 are used for electrically connecting the touch electrode 11 and the at least one touch line 21, and the second openings 32 are used for forming position marks; in the direction perpendicular to the plane of the display panel, the depth of the first opening 31 is H1, the depth of the second opening 32 is H2, and the thickness of the insulating layer 30 is H; wherein H1 is H, and H2 is less than H.
In this embodiment, the touch electrode layer 10 is provided with a plurality of touch electrodes 11 arranged in an array along a first direction x and a second direction y, where the first direction x and the second direction y may be set according to actual situations, for example, a horizontal direction is taken as the first direction x, and the second direction y may be a vertical direction perpendicular to the horizontal direction, or a direction having a certain angle with the horizontal direction, as long as the first direction x and the second direction y are intersected.
The touch electrodes 11 are mainly used for recognizing touch operations of a user, and when a finger of the user touches the display panel, capacitance changes are generated in the corresponding touch electrodes 11 in the touch electrode layer 10, so that position information touched by the user can be determined, and the display panel has a touch recognition function. The touch electrode 11 may form a capacitance in various ways, such as self-capacitance, mutual capacitance, etc., which is not limited in this embodiment, fig. 1 and fig. 2 are only illustrated by taking the former as an example, and will not be described in detail later, and at this time, a capacitance may be formed between the touch electrode 11 and the ground.
The plurality of touch lines 21 on the touch line layer 20 extend along the second direction y, but of course, in other alternative embodiments, the plurality of touch lines 21 may also extend along the first direction x. An insulating layer 30 is disposed between the touch electrode layer 10 and the touch line layer 20, and the material of the insulating layer 30 may include silicide, such as silicon nitride, silicon oxide, and the like; the material of the touch line 21 may include a material having better conductivity, such as a metal, a metal oxide, an alloy, or the like; the material of the touch electrode 11 may also include the above-mentioned material with better conductivity, but it should be ensured that the manufactured touch electrode 11 does not affect the image display effect of the display panel, specifically, the area of the display panel for image display is usually called a display area AA, the area outside the display area AA is usually called a non-display area BB, and the touch electrode layer 10 may be entirely located in the display area AA, at this time, each touch electrode 11 may be made of a conductive material with better light transmittance, such as indium tin oxide, and the like, and of course, the touch electrode layer 10 may also be partially or entirely located in the non-display area BB, which is not specifically limited in this embodiment, and fig. 1 only illustrates that the touch electrode layer 10 is entirely located in the display area AA.
The depth H1 of the first opening 31 in the insulating layer 30 is the same as the film thickness H of the insulating layer 30, that is, the first opening 31 penetrates through the insulating layer 30, so that the touch electrode 11 can be electrically connected to the touch line 21 through the first opening 31, and the position information identified by the touch electrode 11 can be transmitted through the touch line 21, the number of the touch lines 21 electrically connected to each touch electrode 11 can be set to be one or more according to practical situations, and the embodiment does not specifically limit this. The depth H2 of the second opening 32 on the insulating layer is smaller than the film thickness H of the insulating layer 30, and at this time, because the depths of the first opening 31 and the second opening 32 relative to the insulating layer 30 are different, the light transmittances corresponding to the first opening 31 and the second opening 32 are also different, and the light transmittances can be visually represented as different depths of the colors of the patterns of the first opening 31 and the second opening 32, so that a position mark which can be easily recognized by human eyes can be formed through the second opening 32.
When carrying out bad analysis to display panel, through the position mark of discernment second trompil 32 formation, can judge bad position fast to in time maintain this bad position, need not to fix a position with the help of instrument and equipment in addition, can effectively reduce cost of maintenance, improve maintenance efficiency. The shape, number, size and specific position of the second opening 32 on the display panel can be set according to actual needs, for example, when the position mark of the touch line 21 is formed through the second opening 32, the second opening 32 can be set just to the touch line 21, and also can have a certain position deviation with the touch line 21, and the number of the second opening 32 can be the same as that of the touch line 21, and can also be different, as long as the mark requirement can be met.
The first opening 31 and the second opening 32 can be directly formed through the patterned insulating layer 30, so that the influence on the circuit inside the display panel when the second opening 32 forms the position mark can be effectively prevented, and the reliability and the stability of the picture display of the display panel can be improved. Because the depths of the first opening 31 and the second opening 32 are different, the insulating layer 30 may be patterned by using a Half-Tone Mask (Half Tone Mask), that is, by controlling the light transmittance of different regions on the Half-Tone Mask, the patterning degree of the insulating layer 30 in the corresponding region may be controlled; of course, the first opening 31 and the second opening 32 may be formed in other manners, which is not limited in this embodiment.
In the manufacturing process of the display panel, the sequence of forming the touch electrode layer 10 and the touch electrode layer 20 may be set according to actual needs, and fig. 2 only illustrates a film stack structure of sequentially forming the touch electrode layer 20, the insulating layer 30, and the touch electrode layer 10 on the substrate 01.
It should be noted that, in order to more intuitively illustrate the technical solution of the present embodiment, other film layer structures are not illustrated in fig. 1 and fig. 2; meanwhile, in fig. 1, the first opening 31 and the second opening 32 are differentiated by using different shapes, it is to be understood that the shapes of the first opening 31 and the second opening 32 may be the same or different, and this embodiment is not limited in particular.
The display panel provided by the embodiment at least has the following technical effects:
the touch electrode is electrically connected with the touch line through the first opening, so that the display panel has a touch function; simultaneously, form position mark through the second trompil, because the second trompil is different with the degree of depth of first trompil for the insulating layer to can judge the position mark that bad position corresponds fast through the difference of the transmissivity of light, optimize display panel's position mark setting, and need not to fix a position bad position with the help of the instrument in addition, be favorable to reducing cost of maintenance, improve maintenance efficiency. On one hand, the second opening is positioned on the insulating layer, so that the influence of the position mark on the circuit inside the display panel can be effectively prevented, and the reliability and the stability of the picture display of the display panel can be improved; on the other hand, the number and the arrangement mode of the position marks can be flexibly set, and the display device can meet various production and maintenance requirements of display products.
In some alternative embodiments, please continue to refer to fig. 1, the plurality of second openings 32 are divided into at least one second opening group M, and the second opening group M includes at least two second openings 32; within the second group M of openings, each second opening 32 has a first number, the second group M of openings has a second number; wherein, the second number is the combination of the first numbers.
In this embodiment, the plurality of second openings 32 are grouped to obtain a second opening group M composed of at least two second openings 32, and each second opening group M may be used alone to form a position mark or may be combined to form a position mark, which is not limited in this embodiment.
Referring to fig. 3 and fig. 4, each second opening in the second opening group M has a first number, and the first number may be set according to actual needs, for example, the first number is an arabic number from 0 to 9, or an english alphabet from a to Z, and the like, which is not limited in this embodiment. Taking the arabic numerals with the first numbers 0 to 9 as an example, assuming that the second opening group M includes three second openings 32, and the first numbers of the three second openings 32 are 0, 1 and 2, respectively, the second number of the second opening group M can be obtained by combining the three first numbers in a certain order, for example, the second number 012, but also other combinations are possible.
The shapes of the second openings 32 in the second opening group M may be the same, for example, as shown in fig. 3, in this case, in order to more easily identify the number corresponding to the position mark, the depths of the second openings 32 relative to the insulating layer 30 may be set to be different, so that the pattern colors with different depths are visually represented by the light transmittance difference; of course, the shape of each second opening 32 in the second opening group M may also be partially or completely different, for example, as shown in fig. 4, in this case, the number corresponding to the position mark may be directly identified according to the shape, but this embodiment is not limited to this.
Optionally, as shown in fig. 5, in the second opening group M, the second openings 32 are sequentially arranged along the third direction z; the third direction z intersects the first direction x or the second direction y.
In this embodiment, each second trompil 32 in the second trompil group M arranges along third direction z in proper order, is also about to arrange each second trompil 32 in order along the third direction, when carrying out bad analysis to display panel, can be more convenient for read first serial number and second serial number according to distinguishing factors such as pattern depth degree or shape, is favorable to improving efficiency and the accurate degree to bad position location to further improve maintenance efficiency.
It should be noted that the third direction z may intersect with any one of the first direction x and the second direction y, and fig. 5 only illustrates that the third direction z intersects with the first direction x, where the third direction z may be parallel to the second direction y.
Alternatively, referring to fig. 6, the plurality of second openings 32 are divided into at least two second opening groups M; at least one first opening 31 is disposed between two adjacent second opening groups M.
In this embodiment, two adjacent second trompil groups M are kept apart through first trompil 31 to can discern first trompil 31 and second trompil 32 through the depth degree of observing trompil pattern colour in the vision, second trompil 32 between the adjacent first trompil 31 then is a second trompil group M this moment, can effectively improve the reading efficiency of first serial number and second serial number, thereby improve further efficiency and the accurate degree of improving to bad position location.
The arrangement of the at least two second opening groups M on the display panel and the number of the first openings 31 between two adjacent second opening groups M can be set according to actual requirements, which is not specifically limited in this embodiment, and the arrangement shown in fig. 6 is merely taken as an example for explanation: the second openings 32 in the second opening group M are arranged along a third direction z parallel to the first direction x, and the second opening groups M are arranged along the first direction x, so that the second opening group M can be directly separated from the first openings 31 when the number of the second openings 32 is large.
Optionally, referring to fig. 7, the display panel further includes a plurality of mark areas S and at least one separation line 40; separation line 40 extends in a second direction; the plurality of mark areas S are arranged along the first direction x, and at least one separation line 40 is arranged between every two adjacent mark areas S; the mark section S includes a plurality of second opening groups M.
In this embodiment, by providing the plurality of mark areas S arranged along the first direction x, when performing failure analysis, the mark area S where a failure position is located can be quickly determined by the position mark formed by each second opening 32 in the second opening group M, so that maintenance is performed in a partitioned manner, which is beneficial to improving maintenance efficiency; meanwhile, two adjacent mark areas S are separated by the separation line 40, so that the mark area S where the second opening 32 is located can be directly identified by the separation line 40, and the efficiency and the accuracy of poor position positioning can be improved.
In order to quickly identify the separation line 40 in the bad analysis process, the separation line 40 may be made of a material easy to identify, for example, the separation line 40 and the touch line 21 both extend along the second direction y, and the two may be made of different metal materials, so that the separation line 40 may be easily identified due to differences in visual gloss, color, and the like of the different metal materials. Of course, when the film layer area space where the separation line 40 is located is large, the separation line may be distinguished from other lines in the display panel by defining the length, the width, and other dimensions of the separation line 40, but this embodiment does not specifically limit this.
The number of the mark areas S may be set according to actual situations, and fig. 7 illustrates only one mark area S corresponding to each row of the touch electrodes 11, and it can be understood that the position of the mark area S on the display panel is not limited by the size and arrangement of the touch electrodes 11.
Optionally, as shown in fig. 7 and fig. 8, the separation line 40 and the touch line 21 are disposed in the same layer, and at this time, the separation line 40 and the touch line 21 may be formed by patterning the same film layer material, which is beneficial to reducing the difficulty of the manufacturing process, and the film layer where the touch line 21 is located also has enough space to accommodate the separation line 40, but it should be ensured that a sufficient gap is left between the touch line 21 and the separation line 40, so as to prevent the touch line 21 and the separation line 40 from being coupled to each other and affecting the touch accuracy of the display panel. Of course, when the position where one separation line 40 exists is the same as the position of one touch line 21, the separation line 40 may be directly replaced by the touch line 21, that is, one separation line 40 may be provided less, but the visual distinction between the mark regions S is not affected.
Optionally, as shown in fig. 7, a plurality of separation marks 41 are arranged at intervals on the separation line 40, at this time, if the separation line 40 and the touch line 21 cannot be distinguished by naked eyes, the separation marks 41 can be used for distinguishing, and the number of the separation marks 41 is larger, the number of times of moving the field of view by the microscope in the process of analyzing the defect can be smaller, which is beneficial to reducing the time required for determining the defective position.
The separation mark 41 may be patterned directly together with the separation line 40, that is, the two are an integral structure; or the separation mark 41 may also be formed by directly patterning the insulating layer 30, and the specific forming manner may refer to the forming manner of the second opening 32, which is not described herein again; of course, the separation mark 41 may be formed in other manners, but this embodiment is not particularly limited thereto.
It should be noted that, in order to more intuitively illustrate the technical solution of the present embodiment, other film layer structures are not illustrated in fig. 7 and 8; meanwhile, the first opening 31, the second opening 32 and the division mark 41 are distinguished in fig. 7 by different shapes.
Alternatively, as shown in fig. 9, in at least one marking area S, a plurality of second opening groups M are arranged along the second direction y; in the second opening group M, the second openings 32 are sequentially arranged along the third direction z; wherein the third direction z is parallel to the first direction x.
In this embodiment, the plurality of second opening groups M in at least one marking region S are arranged along the second direction y, and the second openings 32 in the second opening groups M are arranged along the direction parallel to the first direction x, so that the second openings 32 in the marking region S visually present a regular arrangement, and at this time, if the second openings 32 are used to form a position mark of the marking region S, it should be ensured that the second numbers corresponding to the second opening groups M in the same marking region S are the same; if the second opening 32 is used to form a position mark of the touch electrode 11, it should be ensured that the second numbers of the second opening groups M corresponding to the same touch electrode 11 are the same; of course, the second opening 32 of the present embodiment may also be used to form a position mark of other objects, and the present embodiment does not specifically limit this.
Optionally, as shown in fig. 10 and fig. 11, the display panel further includes a plurality of scanning lines GL extending along the first direction x, and each of the second openings 32 of the second opening group M is used for forming a position mark of the scanning line GL in the mark area S.
Specifically, the scanning lines GL are mainly used for providing required scanning signals for lines in the display panel, and generally, the number of the scanning lines GL is large, the arrangement is dense, and when performing a failure analysis on the scanning lines GL, if an existing positioning method is adopted to position the scanning lines GL, the operation is quite complicated, and the positioning accuracy is difficult to ensure. In this embodiment, the corresponding second opening group M is configured for the scanning line GL, and the scanning line GL with the bad position can be quickly determined by reading the second number corresponding to the second opening group M, so as to be maintained in time.
Since the scanning lines GL extend in the first direction x, it is ensured that the second opening groups M corresponding to the same scanning line GL in the first direction x have the same second number, and naturally, in the case where defective positions are concentrated, only one mark region S may be provided on the display panel; the second opening 32 may be disposed opposite to the scanning line GL, or may have a certain position deviation with the scanning line GL, as long as the corresponding scanning line GL can be identified clearly; meanwhile, each scanning line GL may be configured with a corresponding second opening group M, or the odd/even scanning lines GL may be configured with a corresponding second opening group M, and the positions of the remaining scanning lines GL may be inferred according to the second number of the configured second opening group M, but the present embodiment is not limited thereto.
It should be noted that, in order to more intuitively illustrate the technical solution of the present embodiment, other film layer structures are not illustrated in fig. 10 and 11.
Referring to fig. 12, in at least one mark section S, a plurality of second opening groups M are arranged along a first direction x; in the second opening group M, the second openings 32 are sequentially arranged along the third direction z; wherein the third direction z is parallel to the second direction y.
In this embodiment, the plurality of second opening groups M in at least one mark area S are arranged along the first direction x, and the second openings 32 in the second opening groups M are arranged along the direction parallel to the second direction y, so that the second openings 32 in the mark area S visually present a regular arrangement manner, and at this time, the second openings 32 may be used to form a position mark of the mark area S or the touch electrode 11 according to actual needs; of course, the second opening 32 of the present embodiment may also be used to form a position mark of other objects, but the present embodiment is not limited to this.
Optionally, referring to fig. 13, the display panel further includes a plurality of data lines DL extending along the second direction y, and in the mark area S, each second opening 32 of the second opening group M is used for forming a position mark of the data line DL.
Specifically, the data lines DL are mainly used for providing required data signals for the lines in the display panel, and generally, the number of the data lines DL is large, the arrangement is dense, and when performing a failure analysis on the data lines DL, if the existing positioning method is adopted to position each scanning line GL, the operation is quite complicated, and the positioning accuracy is difficult to ensure. In this embodiment, a corresponding second open hole group M is configured for the data line DL, and the data line DL where the bad position is located can be quickly determined by reading a second number corresponding to the second open hole group M, so as to perform maintenance in time.
Since the data line DL extends along the second direction y, for the display panel with a larger length in the second direction y, the length of the data line DL disposed thereon is also larger, and in order to reduce the number of times of moving the field of view of the microscope during the failure analysis, a plurality of second opening groups M with the same second number may be configured for the data line DL, which is beneficial to reducing the time required for determining the failure position, but this embodiment does not specifically limit this, and fig. 13 illustrates that only one second opening group M is configured for the data line DL in the mark area S.
The second opening 32 may be disposed opposite to the data line DL, or may have a certain position deviation with the data line DL, as long as the corresponding data line DL can be clearly identified; meanwhile, each data line DL may be configured with a corresponding second open hole group M, or the odd/even data lines DL may be configured with a corresponding second open hole group M, and the positions of the remaining data lines DL may be inferred according to the second number of the configured second open hole group M, but this embodiment is not limited thereto.
It should be noted that, in order to more intuitively illustrate the technical solution of the present embodiment, other film layer structures are not illustrated in fig. 13, and the film layer relationship between the data line DL and the second opening 32 may be referred to as illustrated in fig. 11, which is not described herein again in this embodiment.
