The embodiment of the invention provides a display panel and a manufacturing method thereof. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1 to 4, the display panel 100 includes:
a first substrate and a second substrate 107 disposed opposite to each other;
the frame sealant 101 is connected between the first substrate and the second substrate 107, and the frame sealant 101 is arranged around the display area 109 of the display panel 100;
the first substrate includes a first trace 102 and a second trace 103, the first trace 102 is located on a side of the sealant 101 away from the display area 109, the second trace 103 is located in the display area 109, and the first trace 102 is insulated from the second trace 103.
In the embodiment of the invention, the frame adhesive 101 is used for separating the first wire 102 from the second wire 103, so that the electrostatic damage in the display area 109 caused by the static electricity entering the first wire 102 from the edge of the display panel 100 is avoided, and the antistatic damage capability of the display panel 100 is improved.
The technical solution of the present invention will now be described with reference to specific embodiments.
Referring to fig. 1 to fig. 4, in the present embodiment, the display panel 100 further includes a non-display area surrounding the display area 109, the non-display area includes a bonding area 110 located at one side of the display area 109 and a non-bonding area except the bonding area 110, and the first trace 102 is located in the non-bonding area.
In this embodiment, the first trace 102 may be a dummy trace, a filling block, a character identifier (for distinguishing different display panels), an anti-static trace, or the like that is not electrically connected to the first trace 102.
The Display panel 100 may be a liquid crystal Display panel, an OLED (Organic electroluminescent diode) Display panel, a QLED (Quantum Dot Light Emitting Diodes) Display panel, or other types of Display panels.
In this embodiment, the display panel 100 further includes a display device 104 located in the display area 109, and the second trace 103 is electrically connected to the display device 104.
When the display panel 100 is an OLED display panel, the display device 104 may include a thin film transistor layer on a substrate 106 of the display panel 100, the thin film transistor layer including a thin film transistor; and the light-emitting device layer is positioned on the thin film transistor layer and can comprise an anode layer positioned on the thin film transistor layer, a light-emitting material layer positioned on the anode layer and a cathode layer positioned on the light-emitting material layer.
In this embodiment, the display panel 100 includes a first substrate and a second substrate 107 disposed opposite to the first substrate.
The first substrate includes the substrate 106, the thin film transistor layer, the first trace 102, the second trace 103, and the display device 104.
The second substrate 107 includes a cover plate layer, and the material of the cover plate layer may be glass.
The sealant 101 is located between the first substrate and the second substrate 107, and is used for bonding, fixing and sealing the first substrate and the second substrate 107.
In this embodiment, the second trace 103 may be a scan line, a data line, or another trace electrically connected to the display device 104 in the display area 109.
The second trace 103 may be electrically connected to the thin film transistor, the anode layer, or the cathode layer, and the second trace 103 may also be the cathode layer or the anode layer.
In this embodiment, the non-binding region includes a first sub-region located on the same side of the display region as the binding region 110, and the first trace 102 is located in a region of the non-binding region other than the first sub-region.
By disposing the first trace 102 in the non-bonding region except for the first sub-region, it is avoided that the first trace 102 is too close to the trace located in the bonding region 110 in the first sub-region close to the bonding region 110, which causes electrostatic damage in the bonding region 110 or the display region 109 when static electricity enters the first trace 102 from the edge of the display panel 100.
In this embodiment, the binding region 110 may be disposed adjacent to the display region, or the display panel 100 further includes a bending region between the display region and the binding region 110, or the display panel 100 further includes a fan-out region between the display region 109 and the bending region.
When the display panel 100 further includes the bending region, the bonding region 110 is bent to a side of the substrate 106 of the display panel 100 away from the light emitting side of the display panel 100 through the bending region.
In this embodiment, the display panel 100 further includes a driving chip 105 located in the bonding region 110, a third trace 108 connecting the second trace 103 and the driving chip 105, and a protection layer 111 located on the third trace 108.
In this embodiment, when the display area 109 is disposed adjacent to the bonding area 110, the third trace 108 may be located in the bonding area 110; when the display panel 100 further includes a bending region between the display region 109 and the bonding region 110, the third trace 108 may be located in the bending region and the bonding region 110; when the display panel 100 further includes a fan-out region located between the display region 109 and the bending region, the third trace 108 may be located in the fan-out region, the bending region, and the bonding region 110.
In this embodiment, the third trace 108 and the second trace 103 may be disposed on the same layer, or the third trace 108 and the second trace 103 may be disposed on different layers.
When the third trace 108 and the second trace 103 are disposed on the same layer, the third trace 108 and the second trace 103 may be integrally disposed, that is, the third trace 108 and the second trace 103 may be formed by using the same material and in the same process.
In this embodiment, since the second trace 103 is located on a side of the sealant 101 away from the first trace 102, in order to electrically connect the second trace 103 and the driving chip 105, the third trace 108 at least includes a first connecting portion located on a same side of the sealant 101 as the first trace 102. Therefore, the protection layer 111 is configured to protect the first connection portion, so as to prevent static electricity from entering the first connection portion after entering the first trace 102, which may cause damage to the display device 104 or the driving chip 105.
The material of the protection layer 111 may be ultraviolet glue, silica gel, blue gel, or other materials with insulating property.
In this embodiment, the protective layer 111 and the sealant 101 have a first contact portion.
In this embodiment, the protective layer 111 and the sealant 101 have the first contact portion, so as to completely protect the first connection portion.
In this embodiment, the protective layer 111 can cover the bonding area 110 to protect the third trace 108 and the driving chip 105.
In this embodiment, the first contact portion is located in the non-display area.
In this embodiment, the first contact portion may be located on a side of the sealant 101 away from the display region 109.
By limiting the first contact portion to a side of the sealant 101 away from the display region 109, it is avoided that the first contact portion extends between the substrate 106 and the sealant 101 or between the sealant 101 and the second substrate 107 of the display panel 100, which results in a decrease in the bonding effect between the first substrate and the second substrate 107 and affects the product quality of the display panel 100.
In this embodiment, a distance between the first wire 102 and the sealant 101 is greater than 0, and a distance between the second wire 103 and the sealant 101 is greater than 0.
In this embodiment, by making the distance between the first wire 102 and the sealant 101 greater than 0 and the distance between the second wire 103 and the sealant 101 greater than 0, the sealant 101 is prevented from being damaged by static electricity released between the first wire 102 and the second wire 103, which is beneficial to improving the product quality of the display panel 100.
In this embodiment, the sealant 101 is made of an insulating polymer material, and the width of the sealant 101 is 0.5 mm to 3 mm in the first direction;
the first direction is a direction perpendicular to the extending direction of the sealant 101 in the plane of the display panel 100.
In this embodiment, the sealant 101 may be made of epoxy resin or other insulating polymer materials.
In this embodiment, the extending direction of the sealant 101 is parallel to the side of the display region 109.
When the width of the sealant 101 is less than 0.5 mm, the width of the sealant 101 is too small, and the contact area between the sealant 101 and the first substrate and the second substrate 107 is too small, so that the adhesive force between the first substrate and the second substrate 107 is too low, which is not favorable for sealing the display area 109 of the display panel 100 and bonding the first substrate and the second substrate 107; when the width of the sealant 101 is greater than 3 mm, the width of the sealant 101 is too wide, which is not beneficial to reducing the width of the frame area of the display panel 100 and affects the use feeling of the user on the display panel 100; when the width of the sealant 101 is 0.5 mm to 3 mm, the adhesive force between the first substrate and the second substrate 107 is not too low due to the small width of the sealant 101, and the width of the frame area of the display panel 100 is not easily reduced due to the too wide width of the sealant 101.
In this embodiment, in the second direction, the thickness of the sealant 101 may be 4 to 20 micrometers. The second direction is a direction perpendicular to a plane in which the display panel 100 is located.
When the thickness of the sealant 101 is less than 4 μm, the thickness of the sealant 101 is too small, which results in too low adhesion between the first substrate and the second substrate 107, and is not favorable for sealing the display region 109 of the display panel 100 and bonding the first substrate and the second substrate 107; when the thickness of the sealant 101 is less than or equal to 20 micrometers, the first substrate and the second substrate 107 can be bonded, and therefore, the thickness of the sealant 101 is 4 micrometers to 20 micrometers.
In this embodiment, the first trace 102 includes an anti-static trace, and the anti-static trace is grounded, or the anti-static trace includes a plurality of electrostatic discharge units.
In this embodiment, when the anti-static trace includes a plurality of the electrostatic discharge units, the electrostatic discharge units include protrusions protruding away from the display area 109.
The bumps form discharge tips for timely releasing static electricity, so as to prevent static electricity from being released between the first wire 102 and the second wire 103 and causing damage to the display device 104 or the driving chip 105 due to static electricity entering the second wire 103.
In the embodiment of the invention, the frame adhesive 101 is used for separating the first wire 102 from the second wire 103, so that the electrostatic damage in the display area 109 caused by the static electricity entering the first wire 102 from the edge of the display panel 100 is avoided, and the antistatic damage capability of the display panel 100 is improved.

s100, forming a first trace 102 and a second trace 103 on a substrate 106.
S200, forming a sealant 101 on the substrate 106, wherein the sealant 101 surrounds the display region 109 of the display panel 100.

In the manufacturing method of the display panel provided by the embodiment of the invention, the frame adhesive 101 is used for separating the first wire 102 from the second wire 103, so that the static damage in the display area 109 caused when static enters the first wire 102 from the edge of the display panel 100 is avoided, and the antistatic damage capability of the display panel 100 is improved.
The technical solution of the present invention will now be described with reference to specific embodiments.

In this embodiment, the sealant 101 may be made of epoxy resin or other insulating polymer materials.
In this embodiment, the extending direction of the sealant 101 is parallel to the side of the display region 109.
When the width of the sealant 101 is less than 0.5 mm, the width of the sealant 101 is too small, and the contact areas of the sealant 101 and the first substrate and the second substrate 107 are too small, so that the adhesive force between the first substrate and the second substrate 107 is too low, which is not favorable for sealing the display area 109 of the display panel 100 and bonding the first substrate and the second substrate 107; when the width of the sealant 101 is greater than 3 mm, the width of the sealant 101 is too wide, which is not beneficial to reducing the width of the frame area of the display panel 100 and affects the use feeling of the user on the display panel 100; when the width of the sealant 101 is 0.5 mm to 3 mm, the adhesive force between the first substrate and the second substrate 107 is not too low due to the small width of the sealant 101, and the width of the frame area of the display panel 100 is not easily reduced due to the too wide width of the sealant 101.
In the present embodiment, in the second direction, the thickness of the sealant 101 may be 4 to 20 micrometers. The second direction is a direction perpendicular to a plane in which the display panel 100 is located.
When the thickness of the sealant 101 is less than 4 micrometers, the thickness of the sealant 101 is too small, which results in too low adhesive force between the first substrate and the second substrate 107, and is not favorable for sealing the display region 109 of the display panel 100 and adhering the first substrate and the second substrate 107; when the thickness of the sealant 101 is less than or equal to 20 micrometers, the first substrate and the second substrate 107 can be bonded together, and thus the thickness of the sealant 101 is 4 micrometers to 20 micrometers.
