DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040848 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 placed on top of the encapsulation layer. The color filters are then 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 disposed 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 placed on top of the common electrode.
• A light-blocking layer with holes is placed on top of the encapsulation layer.
• Color filters are placed within the holes of the light-blocking layer, overlapping the openings.

Potential applications of this technology:

• Display devices such as televisions, computer monitors, and smartphones.
• Electronic signage and advertising displays.
• Virtual reality and augmented reality headsets.
• Automotive displays and instrument clusters.

Problems solved by this technology:

• Improved color accuracy and image quality in display devices.
• Enhanced brightness and contrast ratios.
• Reduction of light leakage and reflection.
• Increased durability and protection against environmental factors.

Benefits of this technology:

• Crisp and vibrant display quality.
• Energy-efficient and low power consumption.
• Thin and lightweight design.
• Wide viewing angles and excellent color reproduction.

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.
