Description

Technical Field

Background

GOA (Gate driver on Array) is a technology of arranging a scanning line drive in a non-display area of an array substrate, POA (PS on Array) is a technology of manufacturing a spacer PS (Photo Spacer) on the array substrate, and the two technologies are widely used due to advantages of low cost, low power consumption, narrow frame and the like. When the display panel manufactured by adopting the GOA technology has signal abnormality, a small color film substrate is cut off to expose the test electrode at the uppermost layer of the GOA manufacturing area of the array substrate, and then the corresponding signal point on the test electrode is subjected to stamping by the detection probe, so that the reason of the signal abnormality is obtained.

In the related art, because the uppermost layer of the GOA manufacturing area is the test electrode, if the display panel is pressed by an external force at the position corresponding to the GOA manufacturing area, the test electrode of the GOA manufacturing area will contact with the test electrode on the color film substrate side for short circuit, so that PS needs to be disposed on the test electrode of the GOA manufacturing area, so that the PS covers the surface of the test electrode of the whole GOA manufacturing area, and the color film substrate and the array substrate corresponding to the GOA manufacturing area are supported by the PS, so that the contact short circuit between the test electrode of the GOA manufacturing area and the test electrode on the color film substrate side is avoided. The PS is disposed, so that the detection probe cannot pierce the PS to contact with the test electrode of the GOA manufacturing area, and the detection probe cannot contact the signal point to be detected, which is inconvenient for detecting abnormal signals of the array substrate adopting the GOA technology.

In this embodiment, as shown in fig. 1, the display area 11 of the array substrate 1 is located in the middle of the array substrate 1, and the non-display area 12 of the array substrate 1 is disposed around the display area 11 of the array substrate 1. The display area 11 of the array substrate 1 may be provided with a plurality of data lines and scan lines that are arranged in a staggered manner, and a pixel unit is defined between two adjacent data lines and two adjacent scan lines, and each pixel unit may be driven by signals through the scan lines and the data lines. The non-display area 12 of the array substrate 1 is used for setting the test electrode 13 and a circuit module connected with the test electrode 13, and the test electrode 13 can be connected with the scanning line in the array substrate 1 through a metal layer on the array substrate 1 or directly connected with the scanning line. The detection probe 4 is externally connected with a testing device, the testing device inputs a testing signal to the display area 11 of the array substrate 1 through the detection probe 4, for example, inputs the testing signal to a circuit module connected with the testing electrode 13, receives a waveform feedback signal output by a scanning line in the display area 11 of the array substrate 1, and can judge whether the currently detected scanning line outputs abnormality according to the waveform feedback signal, so that a corresponding signal detection result is obtained.

As shown in fig. 2, the non-display area 12 of the array substrate 1 is provided with a spacer 14 for supporting the color film substrate 2 on the opposite side of the array substrate 1, and the spacer 14 is used for avoiding a common electrode contact short circuit on the color film substrate 2 side and the positive array substrate 1 side when the non-display area 12 of the display panel is pressed. The spacer 14 may be disposed on the test electrode 13, or disposed on the outer periphery of the test electrode 13, or partially disposed on the test electrode 13 and the rest disposed on the outer periphery of the test electrode 13. The material of the spacer 14 includes, but is not limited to, photoresist and color resist.

As shown in fig. 3, the detection point of the detection probe 4 may be any surface portion of the test electrode 13 exposed through the avoidance channel 14a, and by arranging the spacer 14 in the non-display area 12 at the periphery of the display area 11 and penetrating the avoidance channel 14a on the spacer 14, the detection probe 4 for detecting signal abnormality can contact the test electrode 13 in the non-display area 12 through the avoidance channel 14a on the spacer 14, so as to realize detection of abnormal signal on the array substrate 1, thereby realizing avoidance of detection and detection without removing the spacer 14, and facilitating signal detection of the array substrate 1. The clearance channel 14a may be a through hole structure, an opening structure, or the like, which is not limited in this case.

In an embodiment of the present application, as shown in fig. 2 and 3, the spacer 14 is disposed around the outer periphery of the test electrode 13 and surrounds the space-avoiding channel 14a.

In this embodiment, the spacer 14 is disposed around the outer periphery of the test electrode 13, so that the inner peripheral wall of the spacer 14 encloses to form the avoidance channel 14a extending to the test electrode 13, and the annular structure of the spacer 14 is used to support the color film substrate 2 and the array substrate 1, which is beneficial to improving the stability of the thickness of the liquid crystal cell and the structural stability of the non-display area of the display panel. In addition, the spacer 14 is arranged around the outer periphery of the test electrode 13, which is beneficial to enlarging the channel area of the avoidance channel 14a, so that a sufficient access space is provided for the detection probe 4, and the detection probe 4 can conveniently detect the test electrode 13 through the avoidance channel 14a.

As shown in fig. 3 and fig. 4, the materials of the spacers 14 in fig. 3 and fig. 4 are different, so that the spacers 14 are marked by different shadow lines, because the non-display area 12 on the side of the array substrate 1 is arranged corresponding to the non-display area 12 on the side of the color film substrate 2, and the non-display area on the side of the color film substrate 2 is provided with a black matrix layer for shading light, the non-display area of the array substrate cannot have lateral light leakage, and the materials of the spacers 14 can be light shading materials or light transmitting materials, for example, the spacers 14 can be resin, red color resistance, blue color resistance, green color resistance and the like, thereby being beneficial to improving the design flexibility of the spacers 14 and reducing the material cost of the spacers 14.

Alternatively, the spacer 14 includes two spacer segments disposed on opposite sides of the test electrode 13, and the two spacer segments may be disposed adjacent to two long sides of the test electrode 13, or adjacent to two short sides of the test electrode 13, respectively. Therefore, on the premise that the spacer 14 is ensured to reliably support the non-display area 12 of the array substrate 1 and the non-display area of the color film substrate 2, the whole volume of the spacer 14 is reduced, and the material cost and the manufacturing cost of the spacer 14 are saved. The non-display area of the color film substrate 2 and the non-display area 12 of the array substrate 1 are correspondingly arranged, the long side of the test electrode 13 is a side extending along the width direction of the array substrate 1, and the short side of the test electrode 13 is a side extending along the length direction of the array substrate 1.

In an embodiment of the present application, as shown in fig. 2 and 3, the non-display area 12 of the array substrate 1 includes a base layer 121, a first electrode 122, an insulating layer 123, and a second electrode 124, where the first electrode 122 is disposed on the base layer 121, and the insulating layer 123 is disposed on a side of the first electrode 122 facing away from the base layer 121; the second electrode 124 is disposed in the insulating layer 123 and spaced apart from the first electrode 122; the insulating layer 123 is provided with a first via 123a extending toward the first electrode 122 and a second via 123b extending toward the second electrode 124; the test electrode 13 is disposed on a side of the insulating layer 123 opposite to the first electrode 122, and is electrically connected to the first electrode 122 and the second electrode 124 through the first via hole 123a and the second via hole 123 b.

In this embodiment, the first electrode 122 and the second electrode 124 are used for connecting the circuit module of the non-display area 12, the first electrode 122 and the second electrode 124 are electrically connected through the test electrode 13, the first electrode 122 or the second electrode 124 can be used as a conductive electrode connected with the display area 11, when the detection probe 4 is connected with the test electrode 13, an electrical signal input by the detection probe 4 to the test electrode 13 can be transmitted into the display area 11 through the first electrode 122 and the second electrode 124, and a feedback signal in the display area 11 of the array substrate 1 can also be transmitted to the first electrode 122 or the second electrode 124 through the test electrode 13, so that when the detection probe 4 is in contact with the test electrode 13, the detection probe 4, the test electrode 13, the first electrode 122 and the second electrode 124 are mutually conducted, and thus signal detection can be performed by the detection probe 4 on the circuit module connected with the first electrode 122 and the circuit module connected with the second electrode 124. Specifically, the detection probe 4 may be externally connected with a test device, and the test device inputs a test signal to the display area 11 of the array substrate 1 or a circuit module connected to the first electrode 122 or the second electrode 124 through the detection probe 4, the test electrode 13, the first electrode 122 and the second electrode 124, and receives a waveform feedback signal output from the display area 11 of the array substrate 1 or the circuit module connected to the first electrode 122 or the second electrode 124, and by determining whether the waveform feedback signal is abnormal, it is able to understand whether the signal output of the circuit module connected to the first electrode 122 or the second electrode 124 is abnormal, thereby implementing signal detection of the circuit module connected to the first electrode 122 and the circuit module connected to the second circuit. The first electrode 122 and the second electrode 124 may be electrically connected to a driving circuit or a thin film transistor switch on the array substrate 1, so that whether the driving circuit or the thin film transistor switch on the array substrate 1 is abnormal or not can be detected by the above detection method.

In an embodiment of the present application, as shown in fig. 3, the array substrate 1 further includes a support structure 15; the support structure 15 is shown disposed on the base layer 121 and around the outer periphery of the test electrode 13; the spacer 14 is disposed on a side of the support structure 15 facing away from the base layer 121.

In this embodiment, the supporting structure 15 is used for supporting the spacer 14, the supporting structure 15 is located between the base layer 121 and the spacer 14, the supporting structure 15 is configured, the spacer 14 can obtain a higher supporting height through the supporting structure 15, and meanwhile, the height of each part of the spacer 14 can be adjusted through the supporting structure 15, so that the surfaces of the spacer 14 facing away from the base layer 121 are in the same horizontal position, so as to reliably and stably support the color film substrate 2 and the non-display area 12 of the array substrate 1. Wherein the material of the support structure 15 includes, but is not limited to, metal, resin, and color resist, as defined herein.

Alternatively, as shown in connection with fig. 3 and 4, the support structure 15 includes a partial structure of the first electrode 122, the insulating layer 123, and the second electrode 124; the first electrode 122, the insulating layer 123 and the second electrode 124 in the supporting structure 15 are stacked, so that the distance between the spacer 14 and the base layer 121 is equal to the maximum distance between the side of the test electrode 13 facing the base layer 121 and the base layer 121.

In this embodiment, the supporting structure 15 is made of a part of the structure of the first electrode 122, a part of the structure of the insulating layer 123, and a part of the structure of the second electrode 124, and the arrangement and thickness of the first electrode 122, the insulating layer 123, and the second electrode 124 may be the same as those of the previous embodiment, that is, the first electrode 122 in the supporting structure 15 is disposed on the substrate layer 121, the insulating layer 123 is partially disposed on a side of the first electrode 122 facing away from the substrate layer 121, the second electrode 124 is disposed in the insulating layer 123 and is spaced from the first electrode 122, and two sides of the second electrode 124 facing and facing away from the first electrode 122 have a part of the insulating layer 123. Because the test electrode 13 is a metal electrode layer, the thickness of the test electrode is very thin and almost negligible, and therefore, the structural design of the support structure 15 in this embodiment can ensure that when the first electrode 122, the insulating layer 123 and the second electrode 124 are disposed on the base layer 121 in the display area 11 of the array substrate 1 in the same manner, the spacer 14 in the display area 11 of the array substrate 1 can maintain a uniform support height with the spacer 14 in the non-display area 12 of the array substrate 1, so that the display panel composed of the array substrate 1 and the color film substrate 2 can be uniformly supported by the display area of the display panel and the plurality of spacers 14 in the non-display area, thereby avoiding the problem that when the non-display area of the display panel is pressed, the lines below the spacer 14 are pressed and become loaded to be large, and because the lines in the non-display area of the display panel are more sensitive, the load of the related lines becomes large, which causes abnormal line output in the non-display area of the array substrate 1, thereby causing poor display of the display panel.

It should be noted that, because the second electrode 124 does not completely cover the first electrode 122 in the vertical optical path direction of the array substrate 1, there is a situation that the surface of the test electrode 13 facing the base layer 121 is actually high in the partial area position and low in the partial area position, and when the first electrode 122, the insulating layer 123 and the second electrode 124 extend into the display area 11 of the array substrate 1, the spacer disposed in the display area 11 of the array substrate 1 uses the highest position of the insulating layer 123 on the side facing away from the base layer 121 as a reference, in order to ensure that the supporting heights of the spacers in the display area 11 and the non-display area 12 of the array substrate 1 are consistent, in this embodiment, the height position of the highest position of the test electrode 13 is set as a reference for the spacer 14 in the non-display area 12, that is, the distance between the spacer 14 in the non-display area 12 and the base layer 121 is equal to the maximum distance between the side of the test electrode 13 facing the base layer 121 and the base layer 121.

In an embodiment of the present application, as shown in fig. 5 and 6, the spacer 14 has a blocking portion 142 disposed on the test electrode 13; the blocking portion 142 is provided with a clearance channel 14a, and the clearance channel 14a penetrates through one side of the blocking portion 142 facing the test electrode 13 and one side of the blocking portion 142 facing away from the test electrode 13.

In this embodiment, the spacer 14 may cover the upper surface of the test electrode 13, and the avoidance channel 14a may be a through hole structure disposed on the spacer 14, where the hole diameter of the through hole structure is larger than the diameter of the detection probe 4, so that the detection probe 4 can smoothly contact with the test electrode 13 through the through hole structure. By covering the surface of the test electrode 13 with the spacer 14, on one hand, the contact area between the spacer 14 and the test electrode 13 can be increased, the connection tightness of the spacer 14 and the test electrode 13 is improved, and the spacer 14 is prevented from peeling off; on the other hand, the contact area between the spacer 14 and the color film substrate 2 on the opposite side of the array substrate 1 can be increased, so that the stability of the spacer 14 for supporting the array substrate 1 and the color film substrate 2 is improved.

In one embodiment of the present application, as shown in fig. 7 and 8, the spacer 14 includes a plurality of spacer blocks 141 disposed at intervals; the plurality of spacer blocks 141 are disposed around the outer circumference of the test electrode 13, and the side walls of the plurality of spacer blocks 141 facing the test electrode 13 are enclosed to form a space-avoiding channel 14a.

In the present embodiment, the spacer 14 includes a plurality of spacer blocks 141, and the inside of the plurality of spacer blocks 141 forms the space-avoiding passage 14a. The spacer block 14 may have a block structure, the cross-section of which may be square or polygonal, and the number of spacer blocks 141 may be three, four or more than four, when the number of spacer blocks 141 is three, one spacer block 141 may be disposed near the short side of the test electrode 13, and the other two spacer blocks 141 may be disposed near the long side of the test electrode 13, so as to stably support the color film substrate 2 and the array substrate 1; when the number of the spacer blocks 141 is four, the four spacer blocks 141 can be respectively arranged adjacent to the four corners of the test electrode 13, so that the function of stably supporting the color film substrate 2 and the array substrate 1 is achieved; when the number of the spacer blocks 141 is plural, the plurality of spacer blocks 141 may be disposed around the entire test electrode 13 to stably support the color film substrate 2 and the array substrate 1. Wherein the material of each spacer 141 includes, but is not limited to, resin or color resist, and the heights of the spacers 141 are the same. The plurality of spacer blocks 141 can save the overall material cost of the spacer 14, reduce the manufacturing cost and difficulty of the spacer 14, and simultaneously can give consideration to the stability of supporting the non-display area of the display panel.

Alternatively, as shown in fig. 10, the spacer blocks 141 are provided in a long strip shape such that the spacer blocks 141 are provided in a strip or segment-like structure, and each spacer block 141 may be provided adjacent to one long side of the test electrode 13 or adjacent to one short side of the test electrode 13. Therefore, on the premise that the non-display area 12 of the array substrate 1 and the non-display area of the color film substrate 2 are reliably supported by the spacer blocks 141, the whole volume of the spacer 14 is reduced, and the material cost and the manufacturing cost of the spacer 14 are saved. The long side of the test electrode 13 is a side of the test electrode 13 extending along the width direction of the array substrate 1, and the short side of the test electrode 13 is a side of the test electrode 13 extending along the length direction of the array substrate 1.
