DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18299155 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device that includes pixel electrodes, a pixel-defining film with openings, organic light-emitting layers, a common electrode, an encapsulation layer, a light-blocking layer with holes, and color filters. The openings in the pixel-defining film overlap the pixel electrodes, and the organic light-emitting layers are disposed within these openings. The common electrode is positioned between the pixel-defining film and the organic light-emitting layers. The encapsulation layer is placed on top of the common electrode, and the light-blocking layer with holes is then added, overlapping the openings. The color filters are placed within the holes of the light-blocking layer, overlapping the openings.

• The display device includes pixel electrodes, a pixel-defining film, organic light-emitting layers, a common electrode, an encapsulation layer, a light-blocking layer, and color filters.
• The pixel-defining film has openings that overlap the pixel electrodes.
• The organic light-emitting layers are located within the openings of the pixel-defining film.
• The common electrode is positioned between the pixel-defining film and the organic light-emitting layers.
• An encapsulation layer is disposed on top of the common electrode.
• A light-blocking layer with holes is placed on the encapsulation layer, overlapping the openings.
• Color filters are inserted into the holes of the light-blocking layer, overlapping the openings.
• The sides of the openings have concave-convex patterns with convex portions protruding outwardly and concave portions depressed inwardly.
• The color filters partially overlap each other on the light-blocking layer.

Potential applications of this technology:

• Display devices for electronic devices such as smartphones, tablets, and televisions.
• Augmented reality (AR) and virtual reality (VR) headsets.
• Automotive displays and infotainment systems.
• Wearable devices such as smartwatches and fitness trackers.

Problems solved by this technology:

• Improved color accuracy and image quality in display devices.
• Reduction of light leakage and cross-talk between pixels.
• Enhanced contrast and brightness levels.
• Increased durability and lifespan of the display.

Benefits of this technology:

• Higher resolution and sharper images.
• Improved color reproduction and accuracy.
• Reduced power consumption.
• Thinner and lighter display devices.
• Enhanced viewing angles and wider color gamut.

Original Abstract Submitted

A display device comprises pixel electrodes disposed on a substrate and spaced apart from one another, a pixel-defining film disposed on the substrate and including openings, which are spaced apart from one another and overlap the pixel electrodes, organic light-emitting layers disposed in the openings of the pixel-defining film, a common electrode disposed between the pixel-defining film and the organic light-emitting layers, an encapsulation layer disposed on the common electrode, a light-blocking layer disposed on the encapsulation layer and including holes, which overlap the openings and are spaced apart from one another, and color filters disposed in the holes of the light-blocking layer and overlapping the openings. Sides of each of the openings have concave-convex patterns including convex portions that protrude outwardly and concave portions that are inwardly depressed. The color filters are disposed to partially overlap one another on the light-blocking layer.
