DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18361447 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device with an innovative bank structure design for improved performance and efficiency.

• Anode electrodes are present in the display area.
• An inorganic insulating layer covers the anode electrodes.
• A bank structure with openings overlapping the anode electrodes is situated on the insulating layer.
• Light emitting layers are on the anode electrodes and in the openings.
• Cathode electrodes are on the light emitting layers and in the openings.
• A first power line is located in the non-display area.
• A power connection electrode partially overlaps with the first power line and is between the first power line and the display area.
• The bank structure includes hole patterns on the power connection electrode in the non-display area, a first bank layer, and a second bank layer with a protruding tip.

Original Abstract Submitted

A display device includes: a display area and a non-display area; anode electrodes in the display area; an inorganic insulating layer on the anode electrodes; a bank structure on the inorganic insulating layer, and including openings overlapping with the anode electrodes; light emitting layers on the anode electrodes and in the openings; cathode electrodes on the light emitting layers and in the openings; a first power line in the non-display area; and a power connection electrode including through portions partially overlapping with the first power line, and between the first power line and the display area. The bank structure includes: hole patterns on the power connection electrode in the non-display area, and overlapping with the through portions; a first bank layer; and a second bank layer on the first bank layer. The second bank layer includes a tip protruding from a sidewall of the first bank layer.
