It should be understood that the description is only exemplary and is not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the concepts of the present disclosure.
Various structural schematic diagrams according to embodiments of the present disclosure are shown in the drawings. The figures are not drawn to scale, wherein certain details are exaggerated for clarity of presentation and may have been omitted. The shapes of the various regions, layers and relative sizes, positional relationships between them shown in the drawings are merely exemplary, may in practice deviate due to manufacturing tolerances or technical limitations, and one skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions as actually required.
In the context of the present disclosure, when a layer/element is referred to as being "on" another layer/element, it can be directly on the other layer/element or intervening layers/elements may be present therebetween. In addition, if one layer/element is located "on" another layer/element in one orientation, that layer/element may be located "under" the other layer/element when the orientation is turned.
When the condenser lens is provided in the display panel, the condenser lens and the inorganic film layer for packaging the condenser lens are easily separated from the flat layer of the display panel. Therefore, the sealing performance of the display panel is poor, and then the outside air and moisture easily enter the display panel, so that the display effect of the display panel is poor.
Based on the technical problems, the application concept of the application is as follows: a first bulge is arranged on one side, adjacent to the first flat layer, of the condensing lens, a first groove is formed in the first flat layer, and the first bulge is embedded into the first groove. Wherein the length of the first protrusion may be equal to the depth of the first groove. In this way, the condensing lens and the first flat layer can be tightly connected together through the first protrusion and the first groove, so that the condensing lens and the first flat layer are not easy to fall off; and because the inorganic film layer and the condensing lens bear the tensile force from the first flat layer together, when the condensing lens and the first flat layer are not easy to fall off, the inorganic film layer cannot bear the tensile force from the first flat layer alone, so that the inorganic film layer and the first flat layer are not easy to fall off. Furthermore, the tightness of the display panel is improved, and the outside air and moisture are not easy to enter the display panel, so that the display effect of the display panel is improved.
And/or a second groove is formed in the first flat layer, a second protrusion is formed in a region, which is in contact with the first flat layer, of the inorganic film layer, and the second protrusion is embedded into the second groove. Therefore, the first flat layer and the inorganic film layer can be tightly connected together through the second protrusion and the second groove, so that the first flat layer and the inorganic film layer are not easy to fall off. Because the condensing lens is connected with the inorganic film layer, the area on the first flat layer, which is not provided with the condensing lens, is connected with the inorganic film layer, that is, the inorganic film layer and the condensing lens bear the tensile force from the first flat layer together, when the first flat layer and the inorganic film layer are not easy to fall off, the condensing lens cannot bear the tensile force from the first flat layer alone, and the condensing lens and the inorganic film layer are not easy to fall off. Furthermore, the tightness of the display panel is improved, and the outside air and moisture are not easy to enter the display panel, so that the display effect of the display panel is improved.
