DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17942479 titled 'DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
Simplified Explanation
The patent application describes a display device that includes multiple layers and electrodes to create pixel openings for displaying images.
- The display device includes an insulating layer, a first lower electrode, a second lower electrode, a pixel definition layer, and a sacrificial layer.
- The insulating layer is placed on a base layer.
- The first and second lower electrodes are placed on the insulating layer and are spaced apart from each other.
- The pixel definition layer is also placed on the insulating layer and has pixel openings that expose parts of the first and second lower electrodes.
- The sacrificial layer is positioned between the pixel definition layer and the insulating layer and has sacrificial openings that correspond to the pixel openings.
- The pixel definition layer overlaps the first side surface of the sacrificial layer in a plan view.
Potential applications of this technology:
- Display devices such as televisions, computer monitors, and mobile phone screens.
- Virtual reality and augmented reality headsets.
- Automotive displays and instrument panels.
- Wearable technology such as smartwatches and fitness trackers.
Problems solved by this technology:
- Provides a simplified and efficient method for creating pixel openings in a display device.
- Helps in improving the overall image quality and resolution of the display.
- Reduces the complexity and cost of manufacturing display devices.
Benefits of this technology:
- Enhanced display quality with clear and sharp images.
- Improved manufacturing process with simplified steps.
- Cost-effective production of display devices.
- Enables the development of thinner and lighter display devices.
Original Abstract Submitted
A display device includes an insulating layer disposed on a base layer, a first lower electrode disposed on the insulating layer, a second lower electrode disposed on the insulating layer and spaced apart from the first lower electrode, a pixel definition layer disposed on the insulating layer and including pixel openings exposing at least a portion of each of the first lower electrode and the second lower electrode, and a sacrificial layer disposed between the pixel definition layer and the insulating layer and including a first side surface defining sacrificial openings corresponding to the pixel openings. The first side surface is overlapped by the pixel definition layer in a plan view.
