==DISPLAY DEVICE, AND DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240040845 titled 'DISPLAY DEVICE, AND DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR

==Simplified Explanation==

The abstract describes a display panel that includes a driving backplane, a first electrode layer, a pixel definition layer, a light-emitting layer, and a second electrode. The first electrode layer is located on one side of the driving backplane and consists of multiple first electrodes. The pixel definition layer is arranged on the same side as the first electrode layer and exposes each of the first electrodes. The pixel definition layer includes a filling layer and a cut-off layer stacked away from the driving backplane, with the filling layer having a smaller thickness than the first electrode layer. The cut-off layer has a separation slot outside the first electrodes, and a first cut-off slot is provided on a sidewall of the separation slot. The light-emitting layer covers the cut-off layer and the first electrode layer, while the second electrode covers the light-emitting layer.

* The display panel includes a driving backplane, first electrode layer, pixel definition layer, light-emitting layer, and second electrode.
* The first electrode layer is located on one side of the driving backplane and contains multiple first electrodes.
* The pixel definition layer is arranged on the same side as the first electrode layer and exposes each of the first electrodes.
* The pixel definition layer consists of a filling layer and a cut-off layer stacked away from the driving backplane.
* The filling layer has a smaller thickness than the first electrode layer.
* The cut-off layer has a separation slot outside the first electrodes, and a first cut-off slot is provided on a sidewall of the separation slot.
* The light-emitting layer covers the cut-off layer and the first electrode layer.
* The second electrode covers the light-emitting layer.

== Potential Applications ==
* This display panel technology can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
* It can enhance the visual quality and resolution of displays, providing a better viewing experience for users.

== Problems Solved ==
* The display panel addresses the problem of pixel definition and electrode layer arrangement by incorporating a pixel definition layer that exposes each of the first electrodes.
* The separation slot and cut-off layer help prevent interference between the first electrodes and improve the overall performance of the display panel.
* The technology also solves the problem of achieving a thinner display panel by using a filling layer with a smaller thickness than the first electrode layer.

== Benefits ==
* Improved visual quality and resolution of displays.
* Enhanced viewing experience for users.
* Thinner display panel design.
* Reduced interference between electrodes, leading to better performance.


==Original Abstract Submitted==

a display panel includes a driving backplane, a first electrode layer, a pixel definition layer, a light-emitting layer and a second electrode. the first electrode layer is disposed on one side of the driving backplane and includes a plurality of first electrodes. the pixel definition layer is arranged on the side, same as the first electrode layer, of the driving backplane and exposes each of the first electrodes. the pixel definition layer includes a filling layer and a cut-off layer stacked in a direction away from the driving backplane, where the filling layer has a thickness smaller than the first electrode layer. the cut-off layer is provided with a separation slot located outside the first electrodes, and a first cut-off slot is provided on a sidewall of the separation slot. the light-emitting layer covers the cut-off layer and the first electrode layer. the second electrode covers the light-emitting layer.
