Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic diagram of an organic light emitting display device according to an embodiment of the present invention. Referring to fig. 1, an organic light emitting display device according to an embodiment of the present invention includes a substrate 1 and an organic light emitting structure 2, where the substrate 1 includes a substrate 11, a first inorganic film 12, a second inorganic film 13, and a first conductive layer 14 disposed between the substrate 11 and the second inorganic film 13, the organic light emitting structure 2 is disposed on a side of the second inorganic film 13 away from the first inorganic film 12, the organic light emitting display device further includes a second conductive layer 15, the second conductive layer 15 is disposed in a different layer from the first conductive layer 14, and the first conductive layer 14 is electrically connected to the second conductive layer 15.
The second conductive layer 15 may be an original conductive film layer in the organic light emitting display device or an added new conductive film layer, and the embodiment is not limited in particular. The second conductive layer 15 may be disposed inside the substrate 1, for example, the first conductive layer 15 may be disposed between the substrate 11 and the first inorganic film 12, or may be disposed between the first inorganic film 12 and the second inorganic film 13. The second conductive layer 15 can also be disposed outside the substrate 1, for example, on a side of the second inorganic film 13 away from the first inorganic film 12, as long as the first conductive layer 14 and the second conductive layer 15 are different in layer. The first conductive layer 14 and the second conductive layer 15 may be connected by a via or may be connected by another conductive structure, and this embodiment is not particularly limited.
Alternatively, the first conductive layer 14 may be disposed between the substrate 11 and the first inorganic film layer 12, or the first conductive layer 14 may be disposed between the first inorganic film layer 12 and the second inorganic film layer 13. For example, the second conductive layer 15 is disposed in a different layer from the first conductive layer 14, the first conductive layer 14 is disposed between the substrate 11 and the first inorganic film layer 12, and the second conductive layer 15 may be disposed between the first inorganic film layer 12 and the second inorganic film layer 13, that is, the substrate 1 includes the substrate 11, the first conductive layer 14, the first inorganic film layer 12, the second conductive layer 15, and the second inorganic film layer 13, which are sequentially stacked; the first conductive layer 14 is disposed between the first inorganic film layer 12 and the second inorganic film layer 13, and the second conductive layer 15 may be disposed between the substrate 11 and the first inorganic film layer 12, that is, the substrate includes the substrate 11, the second conductive layer 15, the first inorganic film layer 12, the first conductive layer 14, and the second inorganic film layer 13, which are sequentially stacked. Note that fig. 1 exemplarily shows a case where the first conductive layer 14 is disposed between the substrate 11 and the first inorganic film layer 12, and the second conductive layer 15 is disposed between the first inorganic film layer 12 and the second inorganic film layer 13.
In the panel lighting process, the electric field existing between the other charged film layers may affect the charge distribution of the first conductive layer 14, for example, the electric field between the cathode and the anode on the organic light emitting structure 2 may affect the charge distribution on the first conductive layer 14, so that the charges on the first conductive layer 14 are regularly distributed, and a new electric field is formed, which may increase or decrease the electric field strength between the cathode and the anode on the organic light emitting structure 2, and further affect the display performance of the organic light emitting display device. The second conductive layer 15 is disposed in a different layer from the first conductive layer 14, and the second conductive layer 15 is electrically connected to the first conductive layer 14, for example, when the second conductive layer 15 is an original conductive film layer in an organic light emitting display device, the second conductive layer 15 is electrically connected to the first conductive layer 14, the first conductive layer 14 will have a fixed potential, and an external electric field will not affect the first conductive layer 14; when the second conductive layer 15 is a new conductive film layer added, the second conductive layer 15 increases the area of the first conductive layer 14, so that the path of the charge movement is increased, and the electric field intensity formed by the charge movement of the first conductive layer 14 can be reached only by the influence of a larger external electric field, thereby reducing the influence of the electric field between other charged film layers in the display device on the charge distribution on the first conductive layer 14. Therefore, the first conductive layer 14 and the second conductive layer 15 are connected to reduce or eliminate the influence of the external electric field on the charge distribution on the first conductive layer 14, so as to prevent the electric field formed by the first conductive layer 14 from affecting the display performance of the organic light-emitting display device.
The organic light-emitting display device provided by the embodiment of the invention is electrically connected with the second conductive layer through the first conductive layer, so that the first conductive layer is provided with a fixed potential or the movement path of charges of the first conductive layer is increased, the influence of electric fields existing between other charged film layers on the charge distribution of the first conductive layer in the panel lighting process is reduced, the electric field of the first conductive layer is weakened or eliminated, the influence of the first conductive layer on the display performance of the organic light-emitting display device is reduced, and the display uniformity of the organic light-emitting display device is ensured.
Optionally, with continued reference to fig. 1, the second conductive layer 15 is disposed between the first inorganic film layer 12 and the second inorganic film layer 13. Alternatively, fig. 2 is a schematic diagram of another organic light emitting display device provided in an embodiment of the present invention.

By adding the second conductive layer 15 on the substrate 1, the second conductive layer 15 is electrically connected with the first conductive layer 14, so that the path of the charge movement is increased, and a larger external electric field is needed to reach the electric field intensity formed by the charge movement of the original first conductive layer 14, thereby reducing the influence of the electric field between other charged film layers in the display device on the charge distribution on the first conductive layer 14 and avoiding the influence of the larger electric field formed on the first conductive layer 14 on the display performance of the organic light-emitting display device. Or the second conductive layer 15 conducts away the redundant charges on the first conductive layer 14, thereby reducing the phenomenon that the redundant charges on the first conductive layer 14 influence the display performance of the organic light-emitting display device due to the formation of an electric field, and improving the display uniformity of the organic light-emitting display device.
