DISPLAY DEVICE INCLUDING A MULTI-LAYER THIN FILM ENCAPSULATION LAYER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18313664 titled 'DISPLAY DEVICE INCLUDING A MULTI-LAYER THIN FILM ENCAPSULATION LAYER
Simplified Explanation
The display device described in the abstract includes multiple layers to enhance the performance and durability of the light emitting element. Here is a simplified explanation of the patent application:
- The display device has a light emitting element with a pixel electrode, a light emitting layer, and a common electrode.
- A capping layer is placed on the common electrode to protect it.
- An auxiliary layer is added on top of the capping layer.
- The thin film encapsulation layer consists of three layers - a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer.
- The first encapsulation layer includes silicon nitride, the second encapsulation layer includes silicon oxide, and the third encapsulation layer includes silicon oxynitride.
- The thickness of the auxiliary layer is between 200 Å to 1400 Å, the first encapsulation layer is between 400 Å to 3500 Å, the second encapsulation layer is between 200 Å to 2400 Å, and the third encapsulation layer is 4000 Å or more.
Potential Applications: - OLED displays - Electronic devices with high-resolution screens
Problems Solved: - Enhanced performance and durability of display devices - Protection of electrodes from external factors
Benefits: - Improved display quality - Extended lifespan of display devices
Potential Commercial Applications: - Smartphones - Tablets - TVs
Possible Prior Art: - Previous patents related to thin film encapsulation layers in display devices
Unanswered Questions: 1. How does the addition of the auxiliary layer impact the overall performance of the display device? 2. Are there any specific manufacturing processes required to implement the thin film encapsulation layers described in the patent application?
Original Abstract Submitted
A display device includes a light emitting element including a pixel electrode, a light emitting layer, and a common electrode. A capping layer is disposed on the common electrode. An auxiliary layer is disposed on the capping layer. A thin film encapsulation layer includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer. The first encapsulation layer includes a first inorganic insulating layer including silicon nitride; a second inorganic insulating layer including silicon oxide; and a third inorganic insulating layer including silicon oxynitride. The auxiliary layer has a thickness of 200 Å to 1400 Å, the first inorganic insulating layer has a thickness of 400 Å to 3500 Å, the second inorganic insulating layer has a thickness of 200 Å to 2400 Å, and the third inorganic insulating layer has a thickness of 4000 Å or more.
