DISPLAY PANEL AND SPLICING SCREEN - A simplified explanation of the abstract
This abstract first appeared for US patent application 17622850 titled 'DISPLAY PANEL AND SPLICING SCREEN
Simplified Explanation
The patent application describes a display panel and a splicing screen. The display panel consists of a first substrate and a second substrate. The first substrate has a pixel unit with a light-emitting area and a vacant area. The light-emitting area contains a light-emitting diode chip and a pixel driving circuit. The vacant area has at least one conductive hole. The second substrate is positioned on the opposite side of the first substrate from the pixel unit. The pixel driving circuit is electrically connected to a bonding conductive layer in the second substrate through the conductive hole, which eliminates the lower frame of the first substrate and prevents crack extension.
- The display panel includes a first substrate and a second substrate.
- The first substrate has a pixel unit with a light-emitting area and a vacant area.
- The light-emitting area contains a light-emitting diode chip and a pixel driving circuit.
- The vacant area has at least one conductive hole.
- The second substrate is positioned on the opposite side of the first substrate from the pixel unit.
- The pixel driving circuit is electrically connected to a bonding conductive layer in the second substrate through the conductive hole.
- This design eliminates the lower frame of the first substrate and prevents crack extension.
Potential Applications
- Display panels for electronic devices such as televisions, monitors, and smartphones.
- Splicing screens for creating large-scale displays in public spaces, stadiums, and conference rooms.
Problems Solved
- Eliminates the lower frame of the first substrate, reducing the overall size and weight of the display panel.
- Prevents crack extension, improving the durability and lifespan of the display panel.
Benefits
- Compact and lightweight display panels, suitable for portable electronic devices.
- Enhanced durability and longevity, reducing the need for frequent replacements.
- Cost-effective manufacturing process due to the elimination of the lower frame.
Original Abstract Submitted
A display panel and a splicing screen are provided. The display panel includes a first substrate and a second substrate. The pixel unit on the first substrate includes a light-emitting area and a vacant area. The light-emitting area is provided with a light-emitting diode chip and a pixel driving circuit. At least one conductive hole is provided in the vacant area. The second substrate is arranged on a side of the first substrate facing away from the pixel unit, and the pixel driving circuit is electrically connected to a bonding conductive layer included in the second substrate through the conductive hole, which can eliminate a lower frame of the first substrate and prevent crack extension.
