Benefits of technology

The patent is about a display panel that prevents scan lines from breaking when the panel is bent. This is achieved by using a segmented structure for the scan lines, which then connects the sub-scan lines together. This reduces the likelihood of a scan line break, improving the durability of the display panel.

Problems solved by technology

Molybdenum metal is used as a scan line material, but molybdenum metal is a high-temperature brittle material, and the ductility is poor.
When the radius of curvature of the panel is small, the fracture is likely to occur.
When the bending radius of curvature is reduced, the metal line of the scan line is prone to crack.

first embodiment

[0029]In a first embodiment, the scan line of the folding area of the display panel adopts a plurality of sections of molybdenum metal to replace the entire molybdenum metal through the effective display area, and the via of the inter-layer insulating layer and the data lines made by metal having better extensibility are used in the middle. The data line can be of a Ti / Al / Ti three-layer structure, Mo / Al / Mo three-layer structure or Mo / Cu double-layer structure, which can reduce the probability of occurrence of molybdenum metal fracture when the panel is bent.

second embodiment

[0030]FIG. 5 is a cross-section view of one display panel in accordance with the present disclosure. The display panel of the present disclosure may be a flexible, bendable or foldable display panel, and mainly includes: at least one scan line formed by a scan-line metal layer and the horizontal scan line extends through the entire effective display area, and at least one data line 7 formed by the data-line metal layer and the vertical data line extends through the entire effective display area, a conductive material layer for forming a conductive structure in the display panel, and at least one dielectric layer interposed between the scan-line metal layer and the conductive material layer. In the embodiment, the conductive material layer may be an OLED anode material layer for forming an OLED anode. The dielectric layer may include an organic planarization layer (PLN) 8 and an interlayer insulating layer 60.

[0031]The scan lines includes a plurality of sub-scan lines. The sub-scan l...

Abstract

The present disclosure relates to a display panel including at least one scan line formed by a first metal layer, at least one data line formed by a second metal layer, and at least one dielectric layer between the first metal layer and the second metal layer. The scan line is of a segment structure including a plurality of sub-scan lines electrically connecting to connection patterns of the corresponding second metal layer via corresponding via holes of the dielectric layer, the connection patterns of the second metal layer electrically connects the sub-scan lines. The data line is of the segment structure including a plurality of sub-data lines electrically connecting to the connection patterns of the corresponding first metal layer via the corresponding via holes of the dielectric layer, and the connection patterns of the first metal layer electrically connects the sub-data lines.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to a display field, and more particularly to a display panel.BACKGROUND OF THE INVENTION[0002]Flat display panels are widely used in computers, televisions, monitors, portable electronic devices, etc. As the market demands for large-size screens in portable electronic devices continue to increase, large-size displays using flat display panels have been fully developed and commercialized.[0003]With the development of more advanced manufacturing equipment and materials engineering technology, the application of bendable, foldable and curved display in electronic products has become more and more abundant, which has brought great profit opportunities for electronic product manufacturers.[0004]Flexible display is a highly competitive display technology in the future. By mounting flexible-display-medium electronic components and materials on a flexible or flexible substrate, the display is characterized by being able to bend or c...
