DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240204145 titled 'DISPLAY DEVICE
The abstract describes a display device with a substrate divided into sub-pixels, each containing an emission area. The device includes a planarization layer with a concave portion, an anode, a light emitting unit, a bank, a cathode, an encapsulation unit, a lens, and a first light shielding layer.
- The display device has a substrate divided into sub-pixels with emission areas.
- A planarization layer with a concave portion is placed on the substrate.
- An anode is included in the concave portion on the planarization layer.
- A light emitting unit is positioned on the anode in the emission area.
- A bank is located on the anode and planarization layer, excluding the emission area.
- A cathode is placed on the light emitting unit and planarization layer.
- An encapsulation unit is positioned on the cathode.
- A lens is placed on the encapsulation unit corresponding to the emission area.
- Another planarization layer is added on top of the lens.
- A first light shielding layer is disposed on the planarization layer.
Potential Applications: - This technology can be used in high-resolution displays for smartphones, tablets, and TVs. - It can also be applied in augmented reality and virtual reality devices for enhanced visual experiences.
Problems Solved: - The technology addresses the need for improved display quality and efficiency in electronic devices. - It provides a solution for creating brighter and more vibrant displays with better contrast.
Benefits: - Enhanced display performance with increased brightness and color accuracy. - Improved energy efficiency and longer lifespan of the display device. - Greater visual clarity and detail for a more immersive viewing experience.
Commercial Applications: Title: Advanced Display Technology for High-Resolution Devices This technology can be utilized in the consumer electronics industry for manufacturing cutting-edge displays with superior image quality and energy efficiency. It can cater to the growing demand for high-resolution screens in smartphones, tablets, and other electronic devices, enhancing the user experience and setting new standards in display technology.
Questions about Display Device Technology: 1. How does the concave portion in the planarization layer contribute to the performance of the display device? The concave portion helps to optimize the positioning of the anode and improve the efficiency of light emission in the display device.
2. What role does the first light shielding layer play in the overall functionality of the display device? The first light shielding layer helps to prevent light leakage and enhance the contrast ratio of the display, resulting in sharper and more vivid images.
