DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18368693 titled 'DISPLAY DEVICE
Simplified Explanation: The patent application describes a display device with subpixels in an emission area, a driving circuit in a non-emission area, and reference lines for transmitting signals to the subpixels.
- The display device includes a substrate with distinct emission and non-emission areas.
- Subpixels are located in the emission area for displaying images.
- A driving circuit in the non-emission area drives each subpixel individually.
- Reference lines extend between subpixels, branching into branch lines connected to transistors in the driving circuit.
- Each branch line consists of a semiconductor layer and transparent oxide layer crossing into the non-emission area.
- An opaque metal layer is provided on the transparent oxide layer in the non-emission area.
Key Features and Innovation:
- Subpixels in the emission area for displaying images.
- Driving circuit in the non-emission area for individual subpixel control.
- Reference lines and branch lines for transmitting signals to subpixels.
- Use of semiconductor and transparent oxide layers for branch lines.
- Opaque metal layer on branch lines in the non-emission area.
Potential Applications:
- High-resolution displays in electronic devices.
- Improved image quality and color accuracy.
- Enhanced energy efficiency in display technology.
Problems Solved:
- Efficient driving of subpixels in a display device.
- Reduction of signal interference between subpixels.
- Enhanced overall display performance.
Benefits:
- Crisp and clear image display.
- Precise control over individual subpixels.
- Energy-efficient operation.
Commercial Applications: The technology can be applied in various electronic devices such as smartphones, tablets, televisions, and monitors, enhancing their display quality and performance.
Questions about Display Device Technology: 1. How does the use of reference lines improve the performance of the display device? 2. What advantages does the opaque metal layer on the branch lines provide in the non-emission area?
Original Abstract Submitted
A display device including a substrate with an emission area and a non-emission area; a plurality of sub pixels in the emission area; a driving circuit including a plurality of transistors and wiring lines in the non-emission area for selectively driving each sub pixel; and a reference line extending in the emission area between two adjacent sub pixels and including a plurality of branch lines branching from the reference line and being connected to a respective transistor included in the driving circuit for transmitting a reference signal to each subpixel. Further, each branch line comprises a laminated semiconductor layer and transparent oxide layer extending along the emission area and crossing into the non-emission area. In addition, an opaque metal layer is provided on the transparent oxide layer of a corresponding branch line at a position in the non-emission area.
