These terms are only used to distinguish signal lines from one another. For example, a first signal line may also be referred to as a second signal line, and similarly, a second signal line may also be referred to as a first signal line, without departing from the scope of embodiments of the present invention.
An embodiment of the present invention provides a display panel, as shown in fig. 1 to 3, fig. 1 is a top view of the display panel provided in the embodiment of the present invention, fig. 2 is a partially enlarged schematic view of fig. 1, and fig. 3 is a cross-sectional view taken along a direction a1-a2 in fig. 1, where the display panel includes a first display area 1, a second display area 2, and a non-display area 3 located between the first display area 1 and the second display area 2. Wherein, a first signal line 4 is arranged in the first display area 1, a second signal line 5 is arranged in the second display area 2, and the first signal line 4 and the second signal line 5 extend along a first direction respectively; the non-display area 3 is internally provided with a connecting wire 6 and a shading wire 7, the connecting wire 6 electrically connects the first signal wire 4 with the second signal wire 5, the shading wire 7 is positioned on one side of the connecting wire 6 facing the light-emitting surface of the display panel, and in the direction vertical to the surface of the display panel, the shading wire 7 and the connecting wire 6 are at least partially overlapped.
By adopting the display panel provided by the embodiment of the invention, on the premise of ensuring the communication of the signal paths by utilizing the connecting wire 6 to realize the electric connection of the first signal wire 4 and the second signal wire 5, the light-shielding wire 7 is further arranged on one side of the connecting wire 6 facing the light-emitting surface of the display panel, and the light-shielding wire 7 is at least partially overlapped with the connecting wire 6, so that when external environment light (shown by a solid arrow in fig. 3) penetrates through the non-display area 3 and enters the connecting wire 6, reflected light (shown by a dotted arrow in fig. 3) reflected by the connecting wire 6 can be shielded by the light-shielding wire 7 or absorbed by the light-shielding wire 7, and the light-shielding wire 7 cannot further reflect the reflected light, so that the reflected light cannot be transmitted to human eyes, and in the process of watching a user, the light reflection phenomenon in the non-display area 3 can be effectively improved, and the watching.
In addition, by adopting the display panel provided by the embodiment of the invention, the area of the display panel corresponding to the non-display area 3 does not need to be cut, so that a packaging structure does not need to be arranged around the non-display area 3, the manufacturing process flow of the display panel is simplified, the manufacturing cost is reduced, and the narrow frame design of the display panel can be better realized.
Optionally, referring to fig. 3 again, in a direction perpendicular to the surface of the display panel, the light-shielding lines 7 correspond to the connecting lines 6 one to one, and the orthographic projection of the light-shielding lines 7 covers the orthographic projection of the connecting lines 6. Each connecting line 6 is provided with a corresponding shading line 7, so that after external ambient light penetrates through the non-display area 3 and enters the connecting line 6, reflected light reflected by each connecting line 6 can be shaded by the shading line 7 corresponding to the connecting line 6, the shading effect of the shading lines 7 is improved, reflected light is further prevented from entering human eyes, and the light reflection phenomenon of the non-display area 3 is further improved.
Further, referring to fig. 2 and fig. 3 again, the width W1 of the connecting line 6 in the second direction is less than or equal to the width W2 of the light-shielding line 7 in the second direction, wherein the second direction is parallel to the surface of the display panel and perpendicular to the first direction. When the width of the connecting line 6 is smaller than the width of the corresponding shading line, on one hand, even if a user watches the film within the range of an oblique angle, the reflected light reflected by the connecting line 6 can be guaranteed to be shaded by the corresponding shading line 7, and the film watching effect of the user under the oblique angle is improved; on the other hand, when the connecting line 6 and/or the shading line 7 have deviation in the setting position due to factors such as alignment deviation, the shading line 7 can still be ensured to shade the connecting line 6, and the shading effect of the shading line 7 on the reflected light is improved.
Further, referring to fig. 2 again, the width W1 of the connection line 6 in the second direction is smaller than the width W3 of the first signal line 4 or the width W4 of the second signal line 5 in the second direction. Optionally, W1, W2, W3 satisfy: w1 is more than or equal to 2 mu m and less than or equal to 2.5 mu m, W3 is more than or equal to 3 mu m and less than or equal to 4 mu m, and W4 is more than or equal to 3 mu m and less than or equal to 4 mu m.
Compare in first signal line 4 and second signal line 5, with the narrow some that connecting wire 6 set up, not only can reduce the degree of reflection of connecting wire 6 to external environment light, further improve reflection of light phenomenon to, when non-display area 3 is light transmission area, and when being provided with camera element, when camera element makes a video recording, can also reduce the degree of sheltering from of connecting wire 6 to external environment light, improve non-display area 3's light transmittance, improve imaging quality.
Further, as shown in fig. 4, fig. 4 is another partial enlarged view of fig. 1, and the connecting lines 6 include a first connecting line 8 and a second connecting line 9, wherein a length L11 of the first connecting line 8 is greater than a length L22 of the second connecting line 9 in the first direction, and a width W11 of the first connecting line 8 is greater than a width W22 of the second connecting line 9 in the second direction.
For the first connection line 8 and the second connection line 9, when the length L11 of the first connection line 8 is greater than the length L22 of the second connection line 9, WL × R is defined according to the formula RsIt can be seen that, wherein L is the trace length, W is the trace width, and R issFor the resistivity, by further setting the width of the first connecting line 8 to be larger, making the width W11 of the first connecting line 8 larger than the width W22 of the second connecting line 9, it is possible to make the trace loads of the first connecting line 8 and the second connecting line 9 tend to be uniform, thereby reducing the attenuation difference when signals are transmitted on the first connecting line 8 and the second connecting line 9.
Further, referring to fig. 2 again, the width W2 of the light-shielding line 7 in the second direction is less than or equal to the width W3 of the first signal line 4 in the second direction or the width W4 of the second signal line 5 in the second direction. Compared with the first signal line 4 and the second signal line 5, the light shading line 7 is narrower, when the non-display area 3 is a light transmission area and is provided with the camera shooting element, the shielding degree of the light shading line 7 to the external environment light can be reduced when the camera shooting element shoots, the light transmittance of the non-display area 3 is improved, and the imaging quality is improved.
Specifically, the width W2 of the light-shielding line 7 in the second direction is less than 5 μm. For example, W4 may be made to satisfy: 3 μm < W4 < 5 μm. Because a plurality of shading lines 7 are arranged in the non-display area 3, if the width of each shading line 7 is greater than or equal to 5 μm, the shading degree of the shading lines 7 on the non-display area 3 is larger, when the camera shooting element shoots, a large amount of external environment light can be shaded by the shading lines 7 and cannot be transmitted to the camera shooting element, and the imaging quality is influenced. Therefore, by making the width of each light-shielding line 7 smaller than 5 μm, the degree of shielding the external environment light by the light-shielding line 7 can be reduced, and the light transmittance of the non-display area 3 can be improved, thereby improving the imaging quality.
Optionally, when the non-display area 3 is a light-transmitting area, in order to ensure that the non-display area 3 has a high light transmittance and meet the requirement of image pickup, the transmittance of the non-display area 3 for visible light may be greater than 90%.
Alternatively, as shown in fig. 5, fig. 5 is another enlarged partial schematic view of fig. 1, the connecting lines 6 and the shading lines 7 are non-linear, and the connecting lines 6 and the shading lines 7 are exemplarily zigzag or curved.
After the external environment light is transmitted to the connecting line 6, if the connecting line 6 is a linear line, the transmission angle of the reflected light reflected by the connecting line 6 is fixed, and when a user looks at a shadow at a specific angle, the shadow generated after the light is reflected by the connecting line 6 is very obvious. And through setting up connecting wire 6 into nonlinear line type and walk the line, external environment light transmits to connecting wire 6 back, and the propagation direction of the reflection light via connecting wire 6 reflection is dispersed to can realize the vanishing effect to a certain extent. Moreover, the shading lines 7 are further designed to be non-linear type wiring, so that the shapes of the shading lines 7 and the connecting lines 6 are matched, the shading effect of the shading lines 7 on the reflected light can be improved, shadow elimination is further achieved, and the shadow watching experience of a user is improved.
Further, it is understood that, in order to drive the normal operation of the display panel, a data line for supplying a data signal, a gate driving line for supplying a gate driving signal, a light emission control signal line for supplying a light emission control signal, and a power supply signal line for supplying a power supply signal are provided in the display panel. The data lines and the power voltage signal lines extend in a column direction, and the gate driving lines and the light emission control signal lines extend in a row direction.
Optionally, referring to fig. 1 again, the first signal line 4 and the second signal line 5 are data lines or power signal lines, and at this time, the first direction shown in fig. 1 is a column direction. By adopting the arrangement mode, the connecting wire 6 can realize the electric connection of the disconnected data wires at the two sides of the non-display area 3, and ensure the conduction of a data signal transmission path; or, the connecting line 6 can realize the electrical connection of the disconnected power signal lines on the two sides of the non-display area 3, and ensure the conduction of the power signal transmission path.
Alternatively, as shown in fig. 6, fig. 6 is another top view of the display panel according to the embodiment of the present invention, in which the first signal line 4 and the second signal line 5 are gate driving lines or light emitting control signal lines, and at this time, the first direction shown in fig. 6 is a row direction. By adopting the arrangement mode, the connecting wire 6 can realize the electric connection of the grid drive wires disconnected at the two sides of the non-display area 3, and ensure the conduction of the transmission path of the grid drive signals; or, the connecting line 6 can realize the electrical connection of the light-emitting control signal lines disconnected at the two sides of the non-display area 3, and ensure the conduction of the light-emitting control signal transmission path.
Optionally, the connecting line 6 is disposed on the same layer as the first signal line 4 and the second signal line 5, and the connecting line 6 is a metal trace. Illustratively, when the first signal line 4 and the second signal line 5 are gate driving lines, the connection line 6 and the gate driving lines are disposed in the same layer, and when the first signal line 4 and the second signal line 5 are data lines, the connection line 6 and the data lines are disposed in the same layer. By adopting the arrangement mode, the connecting wire 6 can be formed by adopting the same composition process as the first signal wire 4 and the second signal wire 5, and an additional composition process is not needed, so that the process flow is reduced, and the manufacturing cost is reduced.
Alternatively, as shown in fig. 7, fig. 7 is a film layer relationship diagram of the connection line, the first signal line and the second signal line provided in the embodiment of the present invention, the connection line 6 and the first signal line 4 and/or the second signal line 5 are arranged in different layers, the connection line 6 is connected with the first signal line 4 and/or the second signal line 5 through the via 19, and the connection line 6 is a transparent trace. In this case, the connection line 6 may be formed of a transparent conductive material such as indium tin oxide, indium zinc oxide, or indium gallium zinc oxide.
When the connecting wire 6 is a transparent wire, on one hand, based on the good light transmission characteristic of the transparent wire, when the camera shooting element shoots, the shielding degree of the connecting wire 6 to the external environment light can be reduced, the light transmittance of the non-display area 3 is improved, and the imaging quality is improved; on the other hand, because the reflectivity of the transparent wiring to the light is low, after the external environment light is transmitted to the connecting line 6 through the non-display area 3, the light quantity reflected by the connecting line 6 can be reduced, thereby further improving the light reflection phenomenon.
It is understood that, as shown in fig. 8, fig. 8 is another sectional view taken along a direction a1-a2 of fig. 1, and organic light emitting devices 10 including an anode 11, a light emitting layer 12, and a cathode 13 are disposed in the first display region 1 and the second display region 2, which are sequentially stacked. In order to drive the light emitting layer 12 to emit light, the cathode 13 releases electrons toward the light emitting layer 12, and therefore, the cathode 13 needs to be formed using a material having a low work function, and the anode 11 needs to release holes toward the light emitting layer 12, and therefore, the anode 11 needs to be formed using a material having a high work function. If the anode 11 comprises only one metal electrode layer, this will result in fewer holes being released by the anode 11 due to the lower work function of the metal material, thereby affecting the light emitting formation of the light emitting device layer.
Therefore, referring to fig. 8 again, the anode 11 of the light emitting device layer may specifically include a first transparent electrode layer 14, a metal electrode layer 15 and a second transparent electrode layer 16, wherein the first transparent electrode layer 14 and the second transparent electrode layer 16 may specifically be formed of a transparent conductive material such as indium tin oxide, indium zinc oxide or indium gallium zinc oxide. Because the work function of the transparent conductive material is high, the work function of the anode 11 can be improved by additionally arranging the first transparent electrode layer 14 and the second transparent electrode layer 16 in the anode 11, so that more holes are released by the anode 11, and the light-emitting layer 12 is driven to emit light better.
Further, when the connection line 6 is a transparent trace, in order to reduce the process flow and the manufacturing cost, the connection line 6 and the first transparent electrode layer 14 or the second transparent electrode layer 16 may be formed by the same patterning process.
Optionally, as shown in fig. 9, fig. 9 is a schematic diagram of a position where the light-shielding line is disposed according to the embodiment of the present invention, the display panel further includes a planarization layer 17, the planarization layer 17 is located on one side of the first signal line 4 facing the light-emitting surface of the display panel, and the light-shielding line 7 may be located on the planarization layer 17. The light shielding layer is disposed on the planarization layer 17, for example, when the connecting line 6 is disposed on the same layer as the first signal line 4 and the second signal line 5, and is the metal connecting line 6, the light shielding line 7 is closer to one side of the light emitting surface than the connecting line 6, so that the light shielding line 7 can shield the reflected light reflected by the connecting line 6, and the reflected light is prevented from being further transmitted to the human eye.
In addition, utilize planarization layer 17 to fill non-display area 3, promptly, planarization layer 17 does not fretwork the setting in non-display area 3, when display panel takes place to fall, can reduce non-display area 3, the atress difference of first display area 1 and second display area 2, improves the atress homogeneity in each region of display panel, and then improves display panel's anti falling nature.
Alternatively, referring to fig. 8 again, the display panel further includes a cap layer 18, the cap layer 18 is located on a side of the cathode 13 away from the anode 11, and the light-shielding line 7 may be located on the cap layer 18. The light-shielding line 7 is located on the cap layer 18, and the light-shielding line 7 is closer to one side of the light-emitting surface than the connecting line 6, so that the light-shielding line 7 can shield the reflected light reflected by the connecting line 6, and the reflected light is prevented from being further transmitted to human eyes.
Optionally, the light-shielding line 7 has a light-absorbing property, so that when the reflected light reflected by the connecting line 6 is transmitted to the light-shielding line 7, the reflected light can be absorbed by the light-shielding line 7, and the reflected light cannot be further reflected by the light-shielding line 7, so that the reflected light is prevented from further entering human eyes, and the reflection phenomenon is improved. Specifically, the light-shielding line 7 may be formed of a resin material, such as a black resin material.
In addition, the display panel provided by the embodiment of the invention can be a rigid display panel and can also be a flexible display panel. Specifically, when the display panel is a rigid display panel, the display panel includes a first substrate and a second substrate that are disposed opposite to each other, where the first substrate and the second substrate are both rigid substrates, such as glass substrates, the second substrate is located on a side of the first substrate facing the light exit surface, the connection line 6 is located on the first substrate, and the shading line 7 is located on a side of the second substrate facing the first substrate. When the display panel is a flexible display panel, the display panel comprises a flexible first substrate and a thin film packaging layer arranged opposite to the first substrate, the connecting line 6 is positioned on the first substrate, and the shading line 7 is positioned on one side of the thin film packaging layer facing the first substrate.
As shown in fig. 10, fig. 10 is a schematic structural diagram of a display device according to an embodiment of the present invention, and the display device includes the display panel 100. The specific structure of the display panel 100 has been described in detail in the above embodiments, and is not described herein again. Of course, the display device shown in fig. 10 is only a schematic illustration, and the display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic book, or a television.
Since the display device provided by the embodiment of the present invention includes the display panel 100, in combination with fig. 1 to 3, the connection line 6 is used to electrically connect the first signal line 4 and the second signal line 5, so as to ensure the signal path communication, the light-shielding line 7 is further disposed on one side of the connection line 6 facing the light-emitting surface of the display panel, and the light-shielding line 7 and the connection line 6 are at least partially overlapped, when external environment light enters the connection line 6 through the non-display area 3, reflected light reflected by the connection line 6 can be shielded by the light-shielding line 7, so that the reflected light cannot be further transmitted to human eyes, and in the process of viewing the image by a user, the light reflection phenomenon in the non-display area 3 can be effectively improved, and the viewing effect of the user can be improved.
