DISPLAY SUBSTRATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17920626 titled 'DISPLAY SUBSTRATE
The abstract describes a display substrate with sub-pixels, a driving circuit substrate, first electrodes, a pixel definition layer, and a light-emitting material layer. The driving circuit substrate has pixel driving circuits and a protective insulating layer with first vias connecting the first electrodes to the pixel driving circuits. The pixel definition layer includes sub-pixel openings and a partition structure. The light-emitting material layer fills the sub-pixel openings, with the pixel definition layer having a first and second pixel definition sub-layer, where the second sub-layer is wider than the first sub-layer.
- Driving circuit substrate with pixel driving circuits and protective insulating layer
- First electrodes connected to pixel driving circuits through first vias
- Pixel definition layer with sub-pixel openings and partition structure
- Light-emitting material layer filling sub-pixel openings
- Two pixel definition sub-layers with different widths
Potential Applications: - High-resolution displays - OLED screens - Electronic devices with advanced display technology
Problems Solved: - Improved display quality - Enhanced pixel definition - Efficient light emission control
Benefits: - Crisp and clear images - Energy-efficient displays - Enhanced visual experience
Commercial Applications: Title: Advanced Display Substrate Technology for High-Resolution Screens This technology can be utilized in smartphones, tablets, TVs, monitors, and other electronic devices requiring high-quality displays. The market implications include improved user experience, increased demand for devices with superior display quality, and potential growth in the display technology sector.
Questions about Display Substrate Technology: 1. How does the width difference between the two pixel definition sub-layers impact display quality? The width of the second pixel definition sub-layer affects the overall pixel definition and clarity of images on the display.
2. What are the advantages of using sub-pixel openings in the pixel definition layer? Sub-pixel openings allow for precise control of light emission, resulting in sharper images and better color accuracy.
