DISPLAY PANEL AND DISPLAY APPARATUS HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17942775 titled 'DISPLAY PANEL AND DISPLAY APPARATUS HAVING THE SAME
Simplified Explanation
The patent application describes a display panel and a display apparatus that include a resistance structure on a test pattern to prevent damage to the circuit caused by static electricity.
- The display panel includes a substrate, pixel circuits, a test line, an insulating layer, and a resistance structure.
- The pixel circuits are responsible for driving inorganic light emitting devices.
- The test line is located on the substrate and extends from the edge of the substrate.
- An insulating layer is provided on the test line to isolate it.
- The resistance structure includes at least two vertical interconnect accesses (vias) passing through the insulating layer.
- A resistance layer is provided on the insulating layer and connects the at least two vias.
- The test line is discontinuous between the vias, and the resistance layer receives current through one of the vias.
Potential applications of this technology:
- Display panels in electronic devices such as smartphones, tablets, and televisions.
- Industrial displays used in control rooms, manufacturing facilities, and transportation systems.
- Advertising displays in public spaces like shopping malls and airports.
Problems solved by this technology:
- Prevents damage to the circuit of the display panel caused by static electricity introduced into the test pattern.
- Ensures the reliability and longevity of the display panel by protecting it from static electricity.
Benefits of this technology:
- Improved durability and lifespan of the display panel.
- Enhanced performance and functionality of electronic devices.
- Reduced maintenance and repair costs for display panels.
Original Abstract Submitted
A display panel in which a resistance structure is provided on a test pattern to prevent a circuit of the display panel from being damaged by static electricity introduced into the test pattern, and a display apparatus having the same are provided. The display panel includes: a substrate; a plurality of pixel circuits provided on the substrate and configured to drive a plurality of inorganic light emitting devices; a test line provided on the substrate and extending from an edge of the substrate; an insulating layer provided on the test line; and a resistance structure provided on the test line, the resistance structure including: at least two vertical interconnect accesses (vias) passing through the insulating layer; and a resistance layer provided on the insulating layer and extending between the at least two vias, wherein the at least two vias connect the test line and the resistance layer to each other, and the test line is discontinuous at an area between the at least two vias, and wherein the resistance layer is configured to receive, through one of the at least two vias, a current applied to the test line.
