DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18131533 titled 'DISPLAY DEVICE
Simplified Explanation
- Display device with a substrate, planarization layer, pixel electrode, pixel defining layer, lower light emitting layer, charge generation layer, and upper light emitting layer - Protrusions on planarization layer surround center of pixel area - Pixel electrode overlaps pixel area - Pixel defining layer overlaps non-pixel area and exposes portion of pixel electrode - Lower light emitting layer, charge generation layer, and upper light emitting layer stacked on top of each other
Potential Applications
- OLED displays - LED displays - Electronic signage - Wearable technology
Problems Solved
- Improved display quality - Enhanced brightness and contrast - Reduced power consumption - Increased durability and longevity
Benefits
- Higher resolution displays - Energy-efficient technology - Thin and lightweight design - Improved viewing angles
Original Abstract Submitted
A display device includes a substrate including a pixel area and a non-pixel area adjacent to the pixel area, a planarization layer disposed on the substrate and including a plurality of protrusions each having a planar shape surrounding a center of the pixel area, a pixel electrode disposed on the planarization layer and overlapping the pixel area, a pixel defining layer disposed on the planarization layer, overlapping the non-pixel area, and exposing a portion of the pixel electrode, a lower light emitting layer disposed on the pixel electrode, a charge generation layer disposed on the lower light emitting layer, and an upper light emitting layer disposed on the charge generation layer.
