DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18334512 titled 'DISPLAY DEVICE

Simplified Explanation

The abstract describes a display device that includes a substrate, light emitting elements, electrodes, a cover layer, and a color conversion layer. The cover layer is made up of multiple sub-insulating layers with different refractive indices.

The display device includes a substrate with an emission area and a non-emission area.
A plurality of light emitting elements are placed on the substrate.
The light emitting elements are electrically connected to a first and second electrode, which are spaced apart from each other.
A cover layer is placed on top of the electrodes.
The cover layer consists of multiple sub-insulating layers, each containing a first and second layer with different refractive indices.
A color conversion layer is placed on top of the cover layer.

Potential applications of this technology:

This display device can be used in various electronic devices such as smartphones, tablets, televisions, and monitors.
It can also be used in wearable devices such as smartwatches and augmented reality glasses.

Problems solved by this technology:

The use of multiple sub-insulating layers with different refractive indices helps to improve the overall display quality and color accuracy.
It reduces the occurrence of unwanted reflections and enhances the contrast ratio of the display.

Benefits of this technology:

The display device provides improved color accuracy and image quality.
It offers better visibility in different lighting conditions.
The use of multiple sub-insulating layers helps to reduce unwanted reflections, resulting in a clearer and more vibrant display.

Original Abstract Submitted

A display device according to an embodiment includes a substrate including an emission area and a non-emission area, a plurality of light emitting elements disposed on the substrate, a first electrode and a second electrode disposed to be spaced apart from each other and electrically connected to plurality of the light emitting elements, a cover layer disposed on the first electrode and the second electrode, and a color conversion layer disposed on the cover layer. The cover layer includes a plurality of sub-insulating layers each including a first layer and a second layer sequentially stacked. The first layer and the second layer have different refractive indices.
