Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a display panel, a display module and an electronic device with improved shadow elimination capability. Background Art

[0002] With the improvement of consumption level, consumers have higher requirements for product quality and appearance than before. In touch display screens, setting two layers of shadow elimination layers on the circuit surface of the touch screen will significantly improve the quality of the product, and adding two layers of shadow elimination layers will also make the touch screen more integrated in appearance, and the circuit pattern on the panel will not be easily perceived from the appearance. However, since both layers of shadow elimination layers require the entire surface of the glass substrate to be coated, the MOALMO film layer at the binding position in the glass substrate cannot be covered by an insulator, so the second shadow elimination layer at the binding position needs to be etched away to expose the MOALMO film layer at the binding position, but when etching the second shadow elimination layer at the binding position, the etching cream will etch away the first shadow elimination layer. In addition, after the etching cream contacts the BM layer below the first shadow elimination layer, the BM layer has no coating protection, which will also cause the ink at this location to be destroyed, which will not only affect the shadow elimination effect, but also produce different colors at the binding position after being irradiated with UV light.

[0025] First, see Figure 1-2 The embodiment of the utility model provides a display panel with improved shadow elimination capability, comprising: a glass substrate 100, and a first shadow elimination layer 101, a BM layer 102, a second shadow elimination layer 103, a first ITO layer 104, a first OC insulating layer 105, a second ITO layer 106, a MoAlMo film layer 107, a second OC insulating layer 108 and a third shadow elimination layer 109 arranged on the glass substrate from bottom to top;

[0027] The technical solution of the embodiment of the utility model can greatly avoid poor display phenomena, such as the shadow problem caused by the glass substrate, the first ITO layer and the second ITO layer, by setting the first shadow elimination layer, the second shadow elimination layer and the third shadow elimination layer, thereby improving the quality and display effect of the display panel; the second shadow elimination layer can also improve the bonding ability of the insulating layer with other film layers (such as the touch structure layer); in addition, the first OC insulating layer and the second OC insulating layer located on the binding area are both covered in other areas except the MoAlMo film layer, which can protect the first shadow elimination layer and the BM layer from being corroded by the etching solution when etching the second shadow elimination layer at the binding position, thereby avoiding the heterochromatic situation at the binding position.

Secondly, since the second shadow elimination layer is coated on the entire surface, it is necessary to etch the second shadow elimination layer within the binding area 200 to expose the MoAlMo film layer within the binding area. During the etching process, due to the protection of the first OC insulating layer and the second OC insulating layer, the first shadow elimination layer and the BM layer thereunder will not be affected, thereby avoiding the situation of different colors affecting the shadow elimination effect and the binding position.
