Embodiment 1
[0050] figure 1 A schematic cross-sectional view of an array substrate according to Embodiment 1 of the present invention is shown. refer to figure 1 , the array substrate includes a substrate 10, and an electronic device formed on the substrate 10 and a first composite layer 20 between adjacent electronic devices, wherein the first composite layer 20 includes at least an organic planar layer 30, that is, it can Part or all of the originally formed inorganic film layers between adjacent electronic devices can be replaced by the highly flexible organic flat layer 30, so that part of the stress on the array substrate can be released, thereby improving the flexibility of the entire display panel, and avoiding electronic devices due to bent and damaged. In the actual preparation process of the array substrate, after the inorganic film layer is formed between adjacent electronic devices, part or all of the inorganic film layer can be removed to form a film layer gap, and then the...
Embodiment 2
[0062] refer to image 3 , shows a flow chart of the steps of a method for manufacturing an array substrate according to Embodiment 2 of the present invention, and the method may include the following steps:
[0063] Step 301: Provide a base.
[0064] In the embodiment of the present invention, the base may be a flexible base, or a rigid base with relatively high flexibility.
[0065] Step 302: forming electronic devices and inorganic composite layers between the electronic devices on the substrate.
[0066] In the embodiment of the present invention, the electronic device may include a thin film transistor, a storage capacitor and wiring. Specifically, refer to Figure 4 , an inorganic isolation buffer layer can be formed on the substrate first, and then an active layer can be formed on the inorganic isolation buffer layer through a patterning process, and then a first inorganic gate insulating layer can be formed, wherein the first inorganic gate insulating layer covers t...
Embodiment 3
[0079] The embodiment of the present invention also discloses a display panel, including the above-mentioned display substrate.
[0080] In an embodiment of the present invention, the array substrate of the display panel may include a base, electronic devices formed on the base, and a first composite layer located between adjacent electronic devices, wherein the first composite layer includes at least an organic planar layer. In the embodiment of the present invention, part or all of the originally formed inorganic film layers between adjacent electronic devices can be replaced by a highly flexible organic flat layer, so that part of the stress on the array substrate can be released and the electronic devices can be avoided due to bending. The damage improves the flexibility of the entire display panel.
