DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18309561 titled 'DISPLAY DEVICE

Simplified Explanation

The abstract describes a display device that includes a light-emitting element, a pixel-defining film, a sensing electrode, a light-blocking pattern, and a color filter. The light-emitting element consists of a first electrode, a second electrode, and a light-emitting layer. The pixel-defining film has a pixel opening that exposes the first electrode and includes a sensing electrode. A light-blocking pattern is present on the sensing electrode, and a color filter is applied on top of the sensing electrode. The light-blocking pattern consists of a first pattern part and a second pattern part, which have different optical densities with respect to first light.

The display device includes a light-emitting element with a first and second electrode, and a light-emitting layer.
A pixel-defining film with a pixel opening exposes the first electrode.
The pixel-defining film also includes a sensing electrode.
A light-blocking pattern is present on the sensing electrode.
A color filter is applied on top of the sensing electrode.
The light-blocking pattern has two parts with different optical densities.

Potential applications of this technology:

Display devices: This technology can be used in various display devices such as televisions, computer monitors, smartphones, and tablets.
