DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240222585 titled 'DISPLAY DEVICE
The abstract describes a display device with a substrate containing multiple sub-pixels, each with a light-emitting diode. A planarization layer covers the diodes, featuring a first contact hole that narrows from top to bottom, minimizing exposure of the diode's side surface and preventing disconnection of the pixel electrode.
- Display device with substrate and multiple sub-pixels
- Each sub-pixel has a light-emitting diode
- Planarization layer covers diodes with a first contact hole
- First contact hole narrows from top to bottom
- Minimizes exposure of diode's side surface and prevents disconnection of pixel electrode
Potential Applications: - High-resolution displays - LED screens - Electronic devices with pixelated screens
Problems Solved: - Minimizing exposure of diode's side surface - Preventing disconnection of pixel electrode
Benefits: - Improved display quality - Enhanced durability of electronic devices
Commercial Applications: - Manufacturing of smartphones, tablets, and TVs - Display technology industry
Questions about the technology: 1. How does the narrowing of the first contact hole prevent disconnection of the pixel electrode? 2. What are the advantages of using light-emitting diodes in display devices?
Original Abstract Submitted
according to an aspect of the present disclosure, a display device includes a substrate in which a plurality of sub pixels is defined; a light emitting diode disposed on the substrate in each of the plurality of sub pixels; and a planarization layer which covers the light emitting diode and includes a first contact hole overlapping the light emitting diode. the first contact hole is formed to have a width which is narrowed from an upper portion of the first contact hole toward a lower portion of the first contact hole. accordingly, the first contact hole is formed to have a step shape so that the exposure of the side surface part of the light emitting diode through the first contact hole and the disconnection of the pixel electrode may be minimized.
