Samsung patents display design using color filters to improve pixel structure

Samsung describes a display module where pixels use multiple light-emitting elements of the same color, each paired with a color conversion layer and a color filter. The design includes a conductive light absorption layer on the substrate and partition walls to separate the elements, with specific adhesive layers connecting the components.

Why it mattersThis filing details a specific method for arranging pixel components to manage light and electrical connections, which is a standard engineering approach for refining display panel manufacturing.

In the filing’s own words

A display module is provided. The display module includes a substrate, a conductive light absorption layer provided on a surface of the substrate, and a plurality of pixels electrically coupled to the substrate through the conductive light absorption layer. Each of the plurality of pixels may include a first self-luminescence element, a second self-luminescence element and a third self-luminescence element, each emitting light of a same color, a first color conversion layer corresponding to a light emitting surface of the first self-luminescence element and a second color conversion layer corresponding to a light emitting surface of the second self-luminescence element, and a first color filter corresponding to the first color conversion layer and a second color filter corresponding to the second color conversion layer.

What exactly they claim (claim 1)

1. A display module comprising: a substrate; a conductive light absorption layer provided on a surface of the substrate; and a plurality of pixels electrically coupled to the substrate through the conductive light absorption layer, wherein each of the plurality of pixels comprises: a first self-luminescence element, a second self-luminescence element and a third self-luminescence element, each of the first self-luminescence element, the second self-luminescence element and the third self-luminescence element being configured to emit light of a same color; a first color conversion layer corresponding to a light emitting surface of the first self-luminescence element, wherein a bottom surface of the first color conversion layer directly contacts a top surface of the first self-luminescence element; a second color conversion layer corresponding to a light emitting surface of the second self-luminescence element, wherein a bottom surface of the second color conversion layer directly contacts a top surface of the second self-luminescence element; a first color filter corresponding to the first color conversion layer; a second color filter corresponding to the second color conversion layer, wherein the display module further comprises a partition wall separating the first self-luminescence element and the second self-luminescence element, wherein a width of the first color conversion layer is greater than a width of the first self-luminescence element, and a width of the second color conversion layer is greater than a width of the second self-luminescence element, wherein the conductive light absorption layer directly contacts a lower side surface of the first self-luminescence element and a bottom surface of the partition wall, and wherein the display module further comprises a first optical adhesive directly contacting an upper side surface of the first self-luminescence element, the bottom surface of the first color conversion layer, a side surface of the partition wall, and a top surface of the conductive light absorption layer.
