DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18506750 titled 'DISPLAY DEVICE
The abstract describes a display device with specific power lines and test lines on the substrate to apply different constant voltages for testing purposes.
- The display device includes a substrate with a display area, a pad area for pads, and a bending area.
- A test line part in the pad area receives a first constant voltage for testing.
- A power line in a different direction from the test line part also receives the first constant voltage.
- Another power line between the first power line and the pads receives a second constant voltage.
- A third power line between the second power line and the pads receives the first constant voltage.
Potential Applications: - This technology can be used in various display devices such as smartphones, tablets, and monitors. - It can also be applied in touchscreens, electronic signage, and wearable technology.
Problems Solved: - The specific arrangement of power lines allows for efficient testing of the display device. - The different constant voltages applied help in identifying and resolving any issues with the device.
Benefits: - Improved testing capabilities for display devices. - Enhanced reliability and performance due to thorough testing procedures.
Commercial Applications: - The technology can benefit manufacturers of electronic devices by streamlining the testing process. - It can lead to higher quality products and increased customer satisfaction in the market.
Questions about the technology: 1. How does the specific arrangement of power lines contribute to the efficiency of testing in the display device? 2. What are the potential challenges in implementing this technology in different types of display devices?
Original Abstract Submitted
A display device includes a substrate including a display area, a pad area where pads are positioned, and a bending area positioned between the display area and the pad area in a plan view; a test line part on the substrate in the pad area adjacent to the bending area, and to which a first constant voltage is applied; a (1-1)-th power line on the substrate in the pad area, adjacent to the test line part in a second direction crossing the first direction, and to which the first constant voltage is applied; a (2-1)-th power line between the (1-1)-th power line and the pads in the plan view, and to which a second constant voltage different from the first constant voltage is applied; and a (1-2)-th power line between the (2-1)-th power line and pads in the plan view, and to which the first constant voltage is applied.
