Background
With the improvement of TFT (Thin Film Transistor) performance, GOA (gate On Array, gate driving unit) technology has been commonly applied to the display panel. The GOA technology has a series of advantages of saving Gate Integrated circuits (Gate drivers), improving product yield, and realizing a narrow frame design of a display panel, and the wiring structure of a general GOA is shown in fig. 1. The GOA comprises a GOA circuit and a GOA Busline (wiring) part, and the frame glue is located outside the GOA Busline and is at a certain distance from the GOA circuit.
However, when researchers in the field pursue a display panel with a narrow frame and coat the frame glue on the GOA Busline to effectively reduce the frame width of the display panel, the protective effect of the frame glue on the GOA Busline is weakened. Compared with the conventional design (as shown in fig. 1), all the sealant is located outside the GOA Busline, which is equivalent to that all the sealants can prevent the invasion of moisture and oxygen in the environment. However, when the frame glue partially covers the GOA Busline in the narrow frame design (as shown in fig. 2), the width of the frame glue at the outermost edge of the GOA Busline from the frame glue is significantly reduced, the protection effect of the frame glue on the goabond is obviously weakened, and when the display panel is subjected to a high-temperature high-humidity test, water vapor easily invades, so that the via hole at the outermost edge of the GOA Busline is corroded, and the line fails.

In this embodiment, the substrate 10 is a glass substrate. The circuit layer 20 is disposed on the surface of the substrate 10. The circuit layer 20 includes a first metal layer 21 disposed on the surface of the substrate 10, a first insulating layer 22 covering the first metal layer 21, a second metal layer 23 disposed on the surface of the first insulating layer 22 away from the first metal layer 21, a second insulating layer 24 covering the second metal layer 23, and a conductive layer 25 covering the first insulating layer 22 and the second insulating layer 24, where the conductive layer 25 is in contact with the second metal layer 23 through a via 251. In general, in the display panel, the first metal layer 21 is a Gate electrode, the first insulating layer 22 is a Gate insulating layer (GI), the second metal layer 23 is a source electrode and a drain electrode, and the second insulating layer 24 is an insulating protective layer. The conductive layer 25 is in contact with the first metal layer 21 through a contact hole 252, and the contact hole 252 penetrates the second insulating layer 24, the second metal layer 23, and the first insulating layer 22. In this embodiment, the first insulating layer 22 and the second insulating layer 24 are made of an inorganic material such as silicon nitride or silicon oxide, and are used to prevent a leakage current from occurring between the first metal layer 21 and the second metal layer 22. The conductive layer 25 is made of Indium Tin Oxide (ITO) and is used for conduction in the wiring layer 20. Further, a first surface 201 of the circuit layer 20 contacting the sealant 30 is a surface of the conductive layer 25 away from the substrate 10, and the side surface 202 is a side surface of the conductive layer 25 away from the display area.
In a direction from the first metal layer 21 to the second metal layer 23 (i.e., in an upward direction in the figure), the first portion 31 of the sealant 30 covers the via 251. Specifically, the first portion 31 includes a first sealant body 311, and the protective material of the first portion 31 is located on a surface of the first sealant body 311 facing the second portion 32 to form a first protective layer 312. The second portion 32 includes a second sealant body 321, the second sealant body 321 is connected to the first sealant body 311, and the protective material of the second portion 32 is located on a contact surface between the second sealant body 321 and the line layer 20 to form a second protective layer 322. In this embodiment, the first protection layer 312 is located on a contact surface of the first sealant body 311 and the circuit layer 20 (that is, the edge of the first surface 201 away from the display region), the second protection layer 322 covers the side surface 202, and the first protection layer 312 and the second protection layer 322 form a continuous protection layer, where the protection layer is used to protect the circuit layer 20. Specifically, the protective layer is a barrier layer made of inorganic insulating materials such as SiNx or SiNx, and is of a single-layer structure, the barrier layer covers the via hole 251, and separates moisture and oxygen in the air outside the display panel, so that the moisture and the oxygen cannot enter a circuit of the panel, and the via hole 251 is prevented from being corroded, and the display panel is prevented from losing efficacy. In another embodiment of this embodiment, the protective layer may be a dry layer made of a dry material such as an aluminum-containing polymer, and moisture and oxygen in the air are fixed in the dry layer to prevent the moisture and oxygen from entering the display panel. It will be appreciated that the protective layer may also be a hydrophobic layer made of a silane-based hydrophobic material, which may also insulate moisture from the display panel, protecting the vias 251 and the wiring layer 20.
Referring to fig. 4, in another embodiment of the display panel according to the present invention, the difference from the above embodiment is that the protection layer includes a hydrophilic layer and a hydrophobic layer, the hydrophobic layer and the hydrophilic layer form an alternately stacked multi-layer structure, and a layer of the protection layer contacting the first sealant body 311, the second sealant body 321, and the circuit layer 20 is the hydrophobic layer. In this embodiment, the protective layer comprises first hydrophobic layer, hydrophilic layer and second hydrophobic layer, the protective layer is three layer construction. The first hydrophobic layer is arranged on the first frame rubber body 311 and the second frame rubber body 321 faces the surface of the line layer 20, moisture and oxygen in the air are prevented from invading, the hydrophilic layer is arranged in the middle of the first hydrophobic layer and the second hydrophobic layer, the first hydrophobic layer cannot be blocked, and invaded moisture and oxygen are trapped in the hydrophilic layer, the second hydrophobic layer is arranged on the first surface 201 and the side surface 202, further, the moisture and oxygen in the hydrophilic layer are prevented from invading the display panel, and the protective layer formed by the three-layer structure furthest protects the via holes 251 and prevents the display panel from being corroded by the moisture and the oxygen. In other embodiments of this embodiment, the protective layer may also have five or seven layers, as long as the outermost layer of the protective layer is a hydrophobic layer, which can protect the display panel from moisture and oxygen.
Referring to fig. 5, a third embodiment of the display panel according to the present invention is different from the two embodiments in that the first sealant body 311 includes a third surface 3111 facing the display region, and the first protection layer 312 is located on the first surface 201 and protrudes out of the third surface 3111. The first protection layer 312 protrudes from the third surface 311 to cover the via hole 251 more completely, so that moisture and oxygen in the air can enter the via hole 251 along a longer path, and the via hole 251 can be better protected from water and oxygen erosion, which may result in device damage.
Referring to fig. 6, a difference between the fourth embodiment of the display panel of the present invention and the third embodiment is that the first protection layer 312 protrudes from the third surface 3111 of the first sealant body 311 and covers the first surface 201 of the circuit layer 20, so that the entire circuit layer 20 is protected by the first protection layer 312, and the device failure caused by the erosion of moisture and oxygen in the via hole 251 and the contact hole 252 is prevented. It should be noted that, in this embodiment, the material of the first protection layer 312 needs to have better adhesion with the sealant body 31 and the semiconductor, which will not pollute the liquid crystal in the liquid crystal display panel and will not affect the display effect of the display panel.
Referring to fig. 7, a fifth embodiment of the display panel according to the present invention is different from the four embodiments in that the first protection layer 312 covers a surface of the first sealant body 311 facing the second portion, and the protection material of the second portion 32 is dispersed in the second sealant body. Generally, the width of the first portion 31 is 1000um and the width of the second portion 32 is 200um along the direction from the display area to the non-display area. Since the thickness of the second portion 32 is small, it is difficult to implement the second sealant body 321 and the second protective layer 322 described in the above embodiments, in this embodiment, the protective material is a dry material similar to an aluminum-containing polymer or a hydrophobic material similar to a silane material, and is mixed in the sealant material in a doped manner, so that the via hole 251 can be protected, moisture and oxygen cannot enter the line of the panel, and the failure of the line layer 20 due to the corrosion of the first metal layer 21 and the second metal layer 23 by moisture and oxygen is prevented.
Referring to fig. 8, a sixth embodiment of the display panel according to the present invention is different from the fifth embodiment in that the protective material of the first portion 31 is dispersed in the first sealant body to protect the via hole 251 and prevent the via hole 251 from being corroded by moisture and oxygen. It can be understood that, since the distance between the second portion 32 and the line layer 20 is much smaller than the distance between the first portion 31 and the line layer 20, in other embodiments described in this embodiment, the density of the protective material in the second sealant body is greater than the density of the protective material in the first sealant body, so as to protect the line layer 20.
The invention also provides a display device which comprises a controller and the display panel, wherein the controller controls the display panel to be opened or closed.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
