Description

The present application relates to display technical fields, particularly display modules, display panels, display devices and electronic devices.

In the current consumer market for electronic products, electronic products such as mobile phones, televisions and computer displays are gradually adopting narrow bezel designs for display devices to achieve relatively high screen-to-body ratios and improve visual perception. It has come to be used for. For display modules in display devices, a currently commonly used solution for ensuring that the display module meets the narrow bezel requirements of the display device is Gate on Array (GOA) technology. .. In GOA technology, the gate drive circuit can be integrated into the array substrate, which reduces the required bezel space compared to conventional wiring modes and reduces the width of the edge region of the display module, resulting in a display device. Bezel becomes narrower.

GOA circuits include devices that are sensitive to static electricity, such as thin film transistor (TFT) devices and capacitors, and are located at the edges of the array substrate and are exposed to a relatively high risk of being damaged by static electricity. Therefore, GOA circuits are subject to relatively high requirements for electrostatic protection. Currently, a commonly used electrostatic protection method for GOA circuits is to cover the GOA circuits with a protective layer. FIG. 1 is a schematic diagram of the local structure of a general display module. The display module includes an array substrate 01, a color film substrate 02, and a rubber frame 03. The array substrate 01 is connected to the color film substrate 02 through the rubber frame 03. The GOA circuit 011 and the protective layer 012 covering the GOA circuit are arranged on the array substrate 01. When electrostatic discharge occurs on the display module, the protective layer 012 has a specific function of blocking static electricity, which reduces the probability that static electricity directly hits the GOA circuit 011 to protect the GOA circuit 011 from static electricity. To implement. Electrostatic discharge generally results from the accumulation of static electricity. However, the existing display module can only block the static electricity from hitting the GOA circuit when the static electricity discharge occurs, and cannot reduce the accumulation of static electricity. When static electricity accumulates in the display module to some extent, static electricity discharge is likely to occur. If the display module is located in an environment prone to electrostatic discharge, the display module is still exposed to a relatively high safety risk. As a result, the reliability of the display module is reduced.

Similarly, the area and coating position of the second conductive layer 422 are based on the distribution of the electrostatic damage-prone region on the side surface of the first substrate 10 facing in the direction opposite to that of the second substrate 20. Should also be set. In another implementation, alternative, the conductive layer 42 may be arranged only on the protective surface, or the conductive layer 42 may be oriented in the direction opposite to the protective surface and the second substrate 20. It may be arranged on each of the side surface of the substrate 10 and the side surface of the second substrate 20 facing in the direction opposite to that of the first substrate 10. In the following, another configuration method of the conductive layer 42 will be described with reference to FIGS. 4a to 6. It should be noted that in FIGS. 4a-6, only the conductive layer corresponding to the protective surface 101 is used as an example.

Therefore, the present application is intended to include these modifications and modifications of the present application. Provided, however, that these modifications and changes are within the scope defined by the claims of the present application and their equivalent techniques.

The present application relates to display technical fields, particularly display modules, display panels, display devices and electronic devices.

In the current consumer market for electronic products, electronic products such as mobile phones, televisions and computer displays are gradually adopting narrow bezel designs for display devices to achieve relatively high screen-to-body ratios and improve visual perception. It has come to be used for. For display modules in display devices, a currently commonly used solution for ensuring that the display module meets the narrow bezel requirements of the display device is Gate on Array (GOA) technology. .. In GOA technology, the gate drive circuit can be integrated into the array board, which reduces the required bezel space compared to conventional wiring modes and reduces the width of the edge region of the display module, resulting in a display device. Bezel becomes narrower.

GOA circuits include devices that are sensitive to static electricity, such as thin film transistor (TFT) devices and capacitors, and are located at the edges of the array substrate and are exposed to a relatively high risk of being damaged by static electricity. Therefore, GOA circuits are subject to relatively high requirements for electrostatic protection. Currently, a commonly used electrostatic protection method for GOA circuits is to cover the GOA circuits with a protective layer. FIG. 1 is a schematic diagram of the local structure of a general display module. The display module includes an array substrate 01, a color film substrate 02, and a rubber frame 03. The array substrate 01 is connected to the color film substrate 02 through the rubber frame 03. The GOA circuit 011 and the protective layer 012 covering the GOA circuit are arranged on the array substrate 01. When electrostatic discharge occurs on the display module, the protective layer 012 has a specific function of blocking static electricity, which reduces the probability that static electricity directly hits the GOA circuit 011 to protect the GOA circuit 011 from static electricity. To implement. Electrostatic discharge generally results from the accumulation of static electricity. However, the existing display module can only block the static electricity from hitting the GOA circuit when the static electricity discharge occurs, and cannot reduce the accumulation of static electricity. When static electricity accumulates in the display module to some extent, static electricity discharge is likely to occur. If the display module is located in an environment prone to electrostatic discharge, the display module is still exposed to a relatively high safety risk. As a result, the reliability of the display module is reduced.

Therefore, when a static charge is generated on the protective surface on which the conductive layer is arranged, static electricity can be conducted to the conductive layer and also to the ground electrode through the conductive layer, so that static electricity can be accumulated on the protective surface. Reduce. This reduces the probability of electrostatic discharge due to the accumulation of static charges and reduces the risk of damage to the gate drive circuit due to static electricity on the protective surface side.

For example, the ground electrode 41 may be arranged on a stepped portion of the first substrate 10 beyond the second substrate 20. A part of the conductive layer 41 is curved so as to be attached above the ground electrode 41, and a via hole may be provided in the first substrate 10. As a result, the overlapping portion between the ground electrode 41 and the conductive layer 42 is connected through the via hole. In another implementation, alternative, the ground electrode 41 may be formed directly on the outer surface of the first substrate 10.

When an electrostatic discharge occurs at a position where the protective surface is located, a current is conducted to the ground electrode 41 through the second conductive layer 422 when it hits the second conductive layer. This releases static electricity. This can reduce the probability that the electrostatic discharge will hit the gate drive circuit 11. Similarly, the probability that electrostatic discharge will occur due to the continuous accumulation of electrostatic charges also by the second conductive layer 422 on the side surface of the first substrate 10 facing in the opposite direction to the second substrate 20.
