ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18148194 titled 'ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE

Simplified Explanation

The patent application describes an organic electroluminescence display device that includes multiple layers of light emitting materials and electrodes.

• The device includes a substrate and two sub-electrodes on the substrate.
• A first light emitting unit is placed on the first sub-electrode, and a charge generation unit is placed on top of it.
• A second light emitting unit is placed on the charge generation unit, and a second electrode is placed on top of it.
• The first light emitting unit consists of a first light emitting layer on the first sub-electrode, and a second light emitting layer on the second sub-electrode.
• The second light emitting unit consists of a third light emitting layer on the first light emitting layer, and a fourth light emitting layer on the second light emitting layer.

Potential applications of this technology:

• Display devices: This technology can be used to create high-quality and energy-efficient displays for various applications, such as smartphones, televisions, and wearable devices.

Problems solved by this technology:

• Improved display quality: The multiple layers of light emitting materials help in achieving better color accuracy and brightness in the display.
