Problems solved by technology
[0003] The time when electrostatic discharge occurs is very short, and the transfer of a large amount of charges in a short time will generate extremely high current, break down semiconductor devices, or generate enough heat to melt semiconductor devices. This kind of hazard is usually not easy to detect. Under the circumstances, some components will be degraded or scrapped, resulting in large economic losses.
Therefore, electrostatic discharge will bring fatal harm to electronic products, which not only reduces the reliability of products, but also increases maintenance costs

The invention relates to a display panel and a display device. The display panel comprises a grid driver disposed in a non-display region; and at least one static protection unit. The grid driver comprises a plurality of first shift register units which are in cascading connection; at least one second shift register unit which is in cascading connection with the first shift register units; and signal lines which are correspondingly in electrical connection with the first shift register units and / or the second shift register unit. The second arrangement area of the second shift register unit in the non-display region is less than the first arrangement area of the first shift register units in the non-display region. The static protection unit is arranged to be adjacent to the second shift register unit. According to the invention, the static protection unit is placed in a gap of the shift register units, thereby effectively reducing the layout space, and facilitating the narrowing of the display panel.
Description
technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] During the production process of the display panel, due to some external factors, such as continuous process operation and handling or environmental changes, etc., electrostatic charges usually accumulate in the panel. Since glass itself is an insulating substance, unless there is a proper discharge path, static charges will remain on the surface of the substrate. When the electrostatic charge accumulates to a certain amount, a discharge (ESD, Electrostatic Discharge) will occur. [0003] The time when electrostatic discharge occurs is very short, and the transfer of a large amount of charges in a short time will generate extremely high current, break down semiconductor devices, or generate enough heat to melt semiconductor devices. This kind of hazard is usually not easy to detect. Under the circumstances, some com...
