The present disclosure relates to the field of display technologies, and in particular, to an array substrate and a display panel.
Background
In the conventional liquid crystal display panel, in order to reduce the size of the bonding region on the array substrate and achieve the effect of realizing a larger display region, a Chip On Film (COF) bonding technology is generally adopted. That is, a Flexible Printed Circuit (FPC) having a chip (IC) is bonded to a bonding lead (lead) region of the liquid crystal panel array substrate, thereby realizing signal transmission.
In order to improve the yield of the lcd panel and prevent the defective products from flowing into the module or the client, a lighting inspection is generally performed after the assembly is completed. By inputting various analog signals, functional defects in display are checked. In order to increase the detection rate, a short-circuit bar (shorting bar) mode is generally adopted for human eye inspection. As shown in fig. 1, the shorting bar SC of the shorting bar area SB in the display panel 8000 is connected to a shorting bar test line SD, and the shorting bar test line SD is connected to a bonding wire BD of a bonding wire area BL, and is generally disposed in the peripheral area of the display panel. After the detection is completed, the short circuit bar SC and the related circuits need to be cut off to prevent the signal transmission of the actual product from being affected. The Laser cut (Laser cut) mode is usually adopted to cut off the shorting bar and the related circuits from the area LC to be cut of the shorting bar test wire SD.
However, in the conventional liquid crystal display panel, in order to improve the photoresist coating characteristics in the post-process, increase the contrast, and reduce the parasitic capacitance, an organic insulating Film (PFA) is usually used as an insulating protective layer instead of a conventional silicon nitride (SiNx) Film or a silicon oxide (SiOx) Film. However, the organic insulating film has a high transmittance, and the photo-thermal absorption is much lower than that of the inorganic film, and there is a problem that a cut remains when laser cutting is performed, that is, a part of the shorting bar test line is not cut, and thus a scratch phenomenon is easily caused when an Electrostatic Discharge (ESD) test is performed.

In one embodiment, as shown in fig. 2, an array substrate 100 is provided, which includes a substrate 10 and a shorting bar region 20 disposed at one side edge of the substrate 10, wherein the shorting bar region 20 includes a first metal layer, a gate insulating layer 22, a light absorbing layer, and a passivation layer (wherein the first metal layer and the light absorbing layer only show a patterned pattern in fig. 2, and the passivation layer includes a first passivation layer 24 and a second passivation layer 25 in fig. 2). The first metal layer is disposed on the substrate 10 and includes a patterned shorting bar test line 211. The gate insulating layer 22 covers the first metal layer. The light absorbing layer is disposed on the gate insulating layer 22, and the light absorbing portion 231 is patterned. The passivation layer covers the light absorption layer. The short circuit bar test line 211 is provided with a part to be cut, and the light absorption part 231 is opposite to the part to be cut of the short circuit bar test line 211.
Specifically, the passivation layer includes a first passivation layer 24 and a second passivation layer 25, the second passivation layer 25 covers the first passivation layer 24, and the first passivation layer 24 and the second passivation layer 25 are made of different materials.
Further, the material of the first passivation layer 24 is an inorganic insulating film, such as one or more of silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiNO), and other organic substances. The material of the second passivation layer 25 is an organic insulating film.
It should be noted that the portion to be cut of the shorting bar testing line 211 refers to a portion that needs to be cut off when the shorting bar and the related circuit are disconnected.
Further, the light absorbing portion 231 is made of metal, and the metal has a high light absorption rate for laser light in laser cutting. The absorption of laser light by each metal will be described in detail below.
In this embodiment, the light absorbing portion 231 of the shorting bar area 20 is disposed opposite to the portion to be cut of the shorting bar test line 211, and the characteristic of high light absorption of the light absorbing portion 231 is utilized to solve the problem of cutting residue caused by high transmittance and low light absorption of the organic insulating film in the passivation layer when the shorting bar area 20 is cut off by laser cutting.
In one embodiment, as in the array substrate 100 shown in fig. 2, the width of the light absorption part 231 is greater than the width of the shorting bar test line 211.
Specifically, the width of the light absorption portion 231 is 3 micrometers wider than the width of the shorting bar test line 211, for example, the width of the shorting bar test line 211 is 12 micrometers, and the width of the light absorption portion 231 is 15 micrometers.
Further, the length of the light absorption part 231 is equal to the length of the portion of the shorting bar test line 211 to be cut.
Specifically, as shown in fig. 3, which is a schematic view of a bottom view of the shorting bar area 20 in the array substrate 100 shown in fig. 2, in fig. 3, the light absorption part 231 is disposed opposite to a portion to be cut of the shorting bar testing line 211, a width L2 of the light absorption part 231 is greater than a width L1 of the shorting bar testing line 211, and a length S2 of the light absorption part 231 is equal to a length S1 of the portion to be cut of the shorting bar testing line 211.
Specifically, the parts to be cut of the plurality of shorting bar test lines 211 are grouped together to form a region to be cut 212, such as the region to be cut 212 in fig. 3.
Specifically, since the width L2 of the light absorption portion 231 is greater than the width L1 of the shorting bar test line 211, and the length S2 of the light absorption portion 231 is equal to the length S1 of the portion of the shorting bar test line 211 to be cut, the portion of the shorting bar test line 211 to be cut is completely covered by the light absorption portion 231. When laser cutting is performed, due to the high absorptivity of light by the light absorption part 231, the portion of the shorting bar test line 211 to be cut, which covers below, is completely cut, forming a schematic diagram after the cutting is completed as shown in fig. 4, the shorting bar test line 211 in the region 212 to be cut is completely cut, and the cutting residue caused by the inorganic insulating film in the passivation layer is solved.
Further, the length S2 of the light absorption portion 231 may also be slightly smaller than the length of the portion to be cut of the shorting bar testing line 211, and the schematic structure shown in fig. 5 is formed after the laser cutting is completed. In fig. 5, a part of the shorting bar test line 211 is still present in the region 212 to be cut, but the shorting bar test line 211 is cut off, so that the purpose of disconnecting the shorting bar and the related circuit is achieved, and the cutting residue caused by the inorganic insulating film in the passivation layer is also solved.
Specifically, the array substrate 100 further includes a second metal layer, the light absorption layer and the second metal layer are disposed in the same layer, and the light absorption layer is formed by the second metal layer.
It should be noted that the second metal layer is not shown in each drawing, and the second metal layer disclosed in the present disclosure is a conventional second metal layer in the array substrate 100, that is, a second metal layer generally used for forming a source/drain and a data line.
Specifically, the light absorbing layer and the second metal layer are prepared in the same process, and the light absorbing portion 231 of the light absorbing layer is formed at the same time when the source/drain and the data line are formed in the second metal layer.
Further, the material of the second metal layer may be other metals such as copper. Fig. 6 is a schematic diagram showing the relationship between the laser absorption rate and the wavelength of each metal, including copper (Cu), gold (Au), nickel (Ni), iron (Fe), and aluminum (Al). As can be seen from the figure, each metal has a high light absorption rate at a laser wavelength of 532 nm used in laser cutting, in which the light absorption rate of metal aluminum is low compared to that of other metals. The light absorption of copper metal is high.
Further, the light absorbing layer is formed of the second metal layer, that is, the material of the light absorbing part 231 is copper. The light absorbing part 231 also has a high light absorption rate due to the high light absorption rate of the metal copper. When laser cutting is adopted, the laser can be used for cutting the organic insulating layer of the passivation layer more easily.
In one embodiment, unlike the above-described embodiments, the length S2 'of the light absorption part 231' is greater than the length S1 of the portion of the shorting bar test line 211 to be cut. As shown in fig. 7, the length S2' of the light absorption part 231' exceeds the region 212 to be cut, and the width L2 of the light absorption part 231' is greater than the width L1 of the shorting bar test line 211.
Specifically, since the width L2 of the light absorption portion 231 'is greater than the width L1 of the shorting bar test line 211, and the length S2' of the light absorption portion 231 'is greater than the length S1 of the portion of the shorting bar test line 211 to be cut, the portion of the shorting bar test line 211 to be cut is completely covered by the light absorption portion 231'. When the laser cutting is performed, due to the high light absorption rate of the light absorption part 231', the portion of the shorting bar test line 211 to be cut, which covers below, is completely cut, forming a schematic diagram after the cutting is completed as shown in fig. 8, the shorting bar test line 211 in the region 212 to be cut is completely cut, and the cutting residue caused by the inorganic insulating film in the passivation layer is solved.
Specifically, the light absorption layer and the second metal layer are arranged at the same layer, but the light absorption layer and the second metal layer are made of different materials.
Furthermore, the light absorption layer is prepared in the short circuit bar area by adopting a metal material different from the material of the second metal layer while the second metal layer is prepared.
Further, the light absorption layer may also be disposed at a different layer from the second metal layer, for example, the light absorption layer is formed in the shorting bar region at the same time when the active layer is formed.
Further, when the light absorbing layer and the second metal layer are disposed in different layers, the metal material of the light absorbing layer may be the same as or different from the material of the second metal layer.
In the present disclosure, the light absorbing layer is made of a metal material, but the present disclosure is not limited thereto, and any material having a good light absorption rate for the laser used in the laser cutting may be used as the material of the light absorbing layer.
