The present application relates to a field of display technology, and in particular, to a display panel and an electronic device.
In the manufacturing process of display panels, in order to detect defective products in a timely manner, a cell test is performed on the display panels. Typically, a detection circuit capable of identifying faults such as signal line short-circuits is designed on an array substrate. For example, a gate detection circuit is used to detect gate scan lines. To improve detection efficiency, two types of detection signals are often employed. Additionally, in order to reduce borders of the display panel, metal lines used to transmit these two types of detection signals are arranged in two separate metal layers, with each metal layer carrying one type of detection signal. However, when a short-circuit occurs between adjacent metal lines in the same metal layer, since it is a short-circuit between identical signals, it cannot be detected as a defect through the cell test. This can lead to missed detections.
This application provides a display panel and an electronic device to alleviate the technical issue of missed detections in the existing display panel during the cell test.
In order to solve the above technical issues, the present application provides a solution as follows.
The present application provides a display panel, including a display area and a first non-display area located on one side of the display area, the display panel further including:

In the display panel according to one embodiment of the present application, a voltage on the fifth gate line is equal to a voltage on the sixth gate line.
In the display panel according to one embodiment of the present application, the display panel further includes a second non-display area located on another side of the display area, wherein the second non-display area is arranged opposite to the first non-display area and provided with the first line groups and the second line groups, and wherein the first line groups and the second line groups in the first non-display area are electrically connected to odd-numbered ones of the gate scan lines, and the first line groups and the second line groups in the second non-display area are electrically connected to even-numbered ones of the gate scan lines.

Please refer to
The display panel 100 further includes a substrate 10 and multiple gate scan lines GL, multiple data lines DL, multiple first line groups R1, and multiple second line groups R2 positioned on the substrate 10. Optionally, the substrate 10 can be a rigid substrate or a flexible substrate. When the substrate 10 is a rigid substrate, the rigid substrate can include a glass substrate, or etc. When the substrate 10 is a flexible substrate, the flexible substrate can include a polyimide (PI) film, an ultra-thin glass film, or the like.
With reference to
The first line groups R1 are positioned on the substrate 10 and are located within the first non-display area NA1. Each of the first line groups R1 includes at least two gate lines extending along the first direction X. Each gate line in the first line groups R1 is electrically connected to a corresponding gate scan line GL, and there is a voltage difference between every two adjacent gate lines.
The second line groups R2 are also positioned on the substrate 10 within the first non-display area NA1. Each of the second line groups R2 includes at least two gate lines extending along the first direction X. Each gate line in the second line groups is electrically connected to a corresponding gate scan line GL, and there is a voltage difference between every two adjacent gate lines. In this manner, adjacent gate lines in a same layer transmit different signals. When a short circuit occurs between adjacent gate lines in the same layer, because it is a short circuit between different signals, the voltage on the gate lines exhibits a significant change after the short circuit. Consequently, the voltage change can be detected through a cell test, effectively reducing the chances of missed detections.
Furthermore, the first line groups R1 and the second line groups R2 are located in different layers, and an orthographic projection of the gate lines in the second line groups R2 projected on the substrate 10 are alternately arranged with an orthographic projection of the gate lines in the first line groups R1 projected on the substrate 10.
Optionally, the first line groups R1 are formed by a first metal layer, and the second line groups R2 are formed by a second metal layer, with the first metal layer located on one side of the second metal layer that is away from the substrate 10. The first line groups R1 or the second line groups R2 are co-located in the same layer as the gate scan lines GL. A number of the gate lines in the first line group R1 is equal to a number of the gate lines in the second line group R2, and the voltage on the gate lines in the first line group R1 is equal to the voltage on the corresponding gate lines in the second line group R2.
Optionally, with reference to
The second line group R2 includes a third gate line G3 and a fourth gate line G4 adjacent to each other, with both the third gate line G3 and the fourth gate line G4 extending along the first direction X and being separated and electrically insulated from each other. The voltage on the third gate line G3 is equal to the voltage on the first gate line G1, and the voltage on the fourth gate line G4 is equal to the voltage on the second gate line G2. Specifically, the voltage being equal means that the voltage amplitude is the same. For example, the voltage on the third gate line G3 is also 9V, and the voltage on the fourth gate line G4 is also −7V.
Additionally, since the first line group R1 and the second line group R2 are located in different metal layers, the first gate line G1 and the third gate line G3 are in different metal layers, and the second gate line G2 and the fourth gate line G4 are in different metal layers, as shown in
Furthermore, referring to
Each second line group R2 also includes multiple connecting lines. In the same second line group R2, each connecting line is electrically connected to a corresponding gate line, and there is a voltage difference between every two adjacent connecting lines. In this way, adjacent connecting lines in the same layer transmit different signals. When a short circuit occurs between adjacent connecting lines in the same layer, because it is a short circuit between different signals, the voltage on the connecting lines after the short circuit exhibits a significant change. The voltage change can be detected through the cell test, thus effectively reducing the chances of missed detections. Certainly, to further reduce the chances of missed detections, along the first direction X, there is a voltage difference between any two adjacent connecting lines in the same metal layer.
The connecting lines in the second line group R2 and the gate lines in the first line group R1 are formed by the same metal layer. Thus, the connecting lines in the second line group R2 and the connecting lines in the first line group R1 are located in different metal layers. This arrangement helps reduce a width of the first non-display area NA1 in the first direction X, subsequently reducing a border of the display panel 100.
Optionally, the second line group R2 also includes a third connecting line C3 and a fourth connecting line C4 adjacent to each other. The third connecting line C3 is electrically connected to the third gate line G3, and part of the third connecting line C3 extends along the second direction Y The fourth connecting line C4 is electrically connected to the fourth gate line G4, and part of the fourth connecting line C4 extends along the second direction Y Along the first direction X, the third connecting line C3 and the fourth connecting line C4 are spaced apart and electrically insulated from each other.
To further reduce the width of the first non-display area NA1 in the first direction X, optionally, an orthographic projection of the connecting lines in the first line group R1 projected on the substrate 10 partially overlaps with an orthographic projection of the connecting lines in the second line group R2 projected on the substrate 10. As shown in
It should be noted that in
Furthermore, the second non-display area NA2 is also provided with multiple first line groups R1 and multiple second line groups R2. The structure of the first line groups R1 in the second non-display area NA2 is the same as the structure of the first line groups R1 in the first non-display area NA1, and the structure of the second line groups R2 in the second non-display area NA2 is the same as the structure of the second line groups R2 in the first non-display area NA1. The difference lies in the fact that the first line groups R1 and second line groups R2 in the first non-display area NA1 are electrically connected to odd-numbered rows of the gate scan lines GL, while the first line groups R1 and second line groups R2 in the second non-display area NA2 are electrically connected to even-numbered rows of the gate scan lines GL.
Furthermore, in the third non-display area NA3, there is a terminal area that includes a first gate terminal area GP1, a second gate terminal area GP2, and a source terminal area SP located between the first gate terminal area GP1 and the second gate terminal area GP2. Both the first gate terminal area GP1 and the second gate terminal area GP2 include gate terminals GP. The gate terminals GP in the first gate terminal area GP1 are electrically connected to the first line groups R1 and the second line groups R2 in the first non-display area NA1, so as to provide gate drive signals to the first line groups R1 and the second line groups R2 in the first non-display area NA1. The gate terminals GP in the second gate terminal area GP2 are electrically connected to the first line groups R1 and the second line groups R2 in the second non-display area NA2, so as to provide gate drive signals to the first line groups R1 and the second line groups R2 in the second non-display area NA2. The source terminal area SP includes source terminals SP that are electrically connected to the data lines DL in the display area, so as to provide data signals to the data lines DL.
Certainly, to establish electrical connections between the gate terminals GP in the third non-display area NA3 and the first line groups R1 or the second line groups R2, there are also fan-out lines in the third non-display area. These fan-out lines are electrically connected to corresponding connecting lines in the line groups (including the first line groups R1 and the second line groups R2).
In order to provide different voltage signals to the connecting lines and the gate lines in each line group, the third non-display area NA3 is provided with a first signal access point GS1 and a second signal access point GS2. The first signal access point GS1 and the second signal access point GS2 offer different voltages, such as the first signal access point GS1 providing a voltage of 9V, and the second signal access point GS2 providing a voltage of −7V. The first gate line G1, the third gate line G3, the first connecting line C1, and the third connecting line C3 are all connected to the voltage of the first signal access point, while the second gate line G2, the fourth gate line G4, the second connecting line C2, and the fourth connecting line C4 are all connected to the voltage of the second signal access point.

Similarly, in the third line group R3 and the fourth line group R4 arranged adjacently, there is a voltage difference between the gate line in the third line group R3 near the fourth line group R4 and the gate line in the fourth line group R4 near the third line group R3.
The third line group R3 includes a fifth gate line G5 and the first gate line G1 arranged adjacently. There is a voltage difference between the fifth gate line G5 and the second gate line G2.

Correspondingly, the display panel 100 further includes multiple fifth line groups R5 and multiple sixth line groups R6 arranged in the same layer as the second line group R2. Between every two adjacent second line groups R2, there are a fifth line group R5 and a sixth line group R6.

In addition, in the fifth line group R5 and the sixth line group R6 arranged adjacently, the gate line in the fifth line group R5 near the sixth line group R6 has a voltage difference from the gate line in the sixth line group R6 near the fifth line group R5.
The fifth line group R5 includes a seventh gate line G7 and the first gate line G1 arranged adjacently. There is a voltage difference between the sixth gate line G6 and the second gate line G2. In the second line group R2 and the fifth line group R5 arranged adjacently, the sixth gate line G6 is positioned close to the second line group R2.

This allows the addition of only a third signal access point GS3 in the third non-display area NA3, which eliminates the need for adding too many signal access points in the third non-display area NA3, reducing the complexity of the cell test.
