DISPLAY DEVICE AND ELECTRONIC DEVICE HAVING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18125269 titled 'DISPLAY DEVICE AND ELECTRONIC DEVICE HAVING THE SAME

Simplified Explanation

The abstract describes a display device that includes pixel electrodes, a pixel defining layer, an encapsulation layer, a sensing electrode, a first insulating layer, and a second insulating layer. The pixel electrodes are disposed on a substrate, and the pixel defining layer is disposed on the pixel electrodes, with pixel openings overlapping the pixel electrodes. The encapsulation layer is disposed on the pixel electrodes and the pixel defining layer. The sensing electrode is disposed on the encapsulation layer. The first insulating layer is disposed on the sensing electrode and has openings overlapping the pixel openings. The second insulating layer is disposed on the first insulating layer and has a higher refractive index than the first insulating layer. The openings of the first insulating layer include at least one protruding extension, and the protruding directions of the extensions formed in each opening include at least eight directions.

• The display device includes pixel electrodes, a pixel defining layer, an encapsulation layer, a sensing electrode, a first insulating layer, and a second insulating layer.
• The pixel electrodes are located on a substrate, and the pixel defining layer is placed on top of the pixel electrodes.
• The pixel defining layer has pixel openings that overlap with the pixel electrodes.
• The encapsulation layer is positioned on the pixel electrodes and the pixel defining layer.
• The sensing electrode is placed on the encapsulation layer.
• The first insulating layer is located on the sensing electrode and has openings that overlap with the pixel openings.
• The second insulating layer is positioned on top of the first insulating layer and has a higher refractive index than the first insulating layer.
• The openings of the first insulating layer contain protruding extensions, and these extensions have protruding directions in at least eight different directions.
