Problems solved by technology

[0007] 1) Adjust and reduce the amplitude of the high / low level (that is, the driving voltage value) loaded on the outer leads of the plurality of grid lines respectively. Since the change of the amplitude affects the intensity of the space electromagnetic wave, when the When the amplitude decreases, the intensity of the space electromagnetic wave also weakens, that is, the rate of change of the space magnetic flux decreases, which in turn affects the electric field of the edge pixel unit close to the outer lead of the grid line in the effective display area of ​​the display panel, so that the The width of the white line becomes narrower or lighter, but this solution does not make said white line disappear
[0008] 2) Increasing the spacing between the outer leads of the plurality of gate lines, so that the intensity of electromagnetic waves in a unit space is weakened, thereby affecting the pixel units at the edge of the outer leads of the plurality of gate lines in the effective display area of ​​the display panel. electric field, making the width of the white line narrow or even disappear, but this solution will greatly increase the size of the peripheral area of ​​the display panel, thus greatly reducing the utilization rate of the peripheral area of ​​the display panel and increasing the cost
[0009] 3) Adjust the timing of the backlight (B / L, back light) and the display panel and increase the delay of the backlight, that is, when the display panel is powered on and initialized, the backlight is not lit, and the backlight is turned on when the display panel works normally , this solution can prevent customers from seeing the white line from the perspective of visual observation, but it does not fundamentally solve the problem of the white line
[0010] It can be seen that none of the above solutions fundamentally solves the problem of the white line

Embodiment 1

[0040] In this embodiment, the array substrate includes a plurality of gate lines, a plurality of data lines, a common electrode and a shielding layer. Wherein, each gate line and data line includes an outer lead, which are respectively called the outer lead of the gate line and the outer lead of the data line, and the number of the outer lead of the gate line is the same as that of the gate line, and the outer lead of the data line is the same as the number of the data line. The same number; the common electrode includes a plurality of outer leads, called the outer leads of the common electrode.

[0041] The shielding layer is arranged above the outer leads of the plurality of grid lines and connected to the grounding point, and is used for shielding space electromagnetic wave radiation excited by voltage changes in the outer leads of the plurality of grid lines. Preferably, the shielding layer covers the outer leads of the plurality of gate lines, and the shielding layer and...

Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 is that in this embodiment, the array substrate does not include the connection layer 8b, and the shielding layer 8a is respectively arranged on the left and right sides of the effective display area 7 above the outer leads 4 of the plurality of gate lines. Connect to two ground points respectively.

[0057] Other structures, methods, and functions in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0059] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the connection layer 8b is disposed above the outer leads of multiple data lines. Specifically, the connection layer 8b is disposed above the outer leads of the multiple data lines located at the bottom of the effective display area 7, that is, the shielding layer 8a and the connection layer 8b form a U-shaped structure.

[0060] Preferably, the connection layer 8b covers the outer leads of the plurality of data lines, and the connection layer 8b and the outer leads of the plurality of data lines are not electrically connected to each other. Further preferably, the insulating layer in the array substrate is also disposed between the connection layer 8b and the outer leads of the multiple data lines, so that the connection layer 8b and the outer leads of the multiple data lines are not electrically connected to each other.

[0061]In this embodiment, the width...

Abstract

The invention provides an array substrate, which comprises a plurality of grid lines, wherein each grid line comprises an outer lead. The array substrate also comprises a shielding layer, wherein the shielding layer is arranged above the outer leads of the grid lines and is connected with an earthing point for shielding space electromagnetic wave radiation excited by the voltage variation in the outer leads of the grid lines. Correspondingly, the invention also provides a manufacture method of the array substrate, a display panel comprising the array substrate and a display device comprising the display panel. According to the array substrate disclosed by the invention, the phenomenon that the left side and the right side of the effective display area on the display panel has white lines because of the space electromagnetic wave radiation excited when the display device is initialized during startup can be avoided.
