DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18396510 titled 'DISPLAY DEVICE
The patent application describes a display device with a substrate containing multiple sub-pixels, each with a light-emitting diode (LED) and a planarization layer covering the LED with a contact hole.
- LED is placed in each sub-pixel on the substrate.
- Planarization layer covers the LED and includes a contact hole.
- Contact hole is formed with a narrowed width from top to bottom, creating a step shape.
- Step shape minimizes exposure of the LED side surface and prevents disconnection of the pixel electrode.
Potential Applications: - Display screens for electronic devices - Signage and advertising boards - Automotive displays
Problems Solved: - Minimizes exposure of LED side surface - Prevents disconnection of pixel electrode
Benefits: - Improved display quality - Enhanced durability of the display device - Reduced maintenance costs
Commercial Applications: Title: "Innovative Display Technology for Enhanced Visuals" This technology can be used in various commercial applications such as smartphones, tablets, TVs, and digital signage, enhancing the visual experience for users and providing a competitive edge in the market.
Questions about the technology: 1. How does the step shape of the contact hole benefit the display device?
- The step shape minimizes exposure of the LED side surface and prevents disconnection of the pixel electrode, improving the overall performance and longevity of the display.
2. What are the potential commercial applications of this display technology?
- This technology can be utilized in smartphones, tablets, TVs, and digital signage, offering enhanced visual quality and durability for various consumer electronics and advertising displays.
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.
