DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240265837 titled 'DISPLAY DEVICE
The display device described in the patent application includes a substrate with a display area for pixels and a non-display area surrounding it, along with crack detection lines, dams, and a common voltage line.
- The first crack detection lines are located in the non-display area to detect any cracks that may occur.
- A first dam separates the crack detection lines from the display area.
- A second dam with sub-layers is positioned between the first dam and the crack detection lines.
- The common voltage line in the non-display area supplies a common voltage to the pixels and has a concave part facing the crack detection lines.
- A second crack detection line is electrically connected to the first crack detection lines and includes a first line part and a first connection part.
Potential Applications: - This technology can be used in various display devices such as smartphones, tablets, and televisions. - It can also be applied in automotive displays, medical monitors, and industrial equipment screens.
Problems Solved: - Helps in early detection of cracks in the display area, preventing further damage. - Ensures the proper functioning of pixels by providing a common voltage line.
Benefits: - Improved durability and longevity of display devices. - Enhanced reliability and performance of the display area. - Cost-effective solution for crack detection in displays.
Commercial Applications: Title: Advanced Display Device Technology for Enhanced Durability and Performance This technology can be utilized by display manufacturers to create more robust and reliable products, catering to a wide range of industries such as consumer electronics, automotive, healthcare, and manufacturing.
Questions about Display Device Technology: 1. How does the placement of crack detection lines improve the durability of the display device? - The crack detection lines in the non-display area help in early detection of cracks, preventing them from spreading to the display area.
2. What is the significance of the concave part in the common voltage line facing the crack detection lines? - The concave part helps in ensuring proper contact and functionality of the common voltage line, enhancing the overall performance of the display device.
Original Abstract Submitted
a display device includes: a substrate including a display area where pixels are arranged and a non-display area positioned around the display area; first crack detection lines disposed in the non-display area; a first dam positioned between the first crack detection lines and the display area; a second dam between the first dam and the first crack detection lines and including sub-layers; a common voltage line disposed in the non-display area, and which provides a common voltage to the pixels, and includes a concave part defined at an edge of the common voltage line facing the first crack detection lines; a second crack detection line electrically connected to the first crack detection lines, positioned between the first crack detection lines and the display area, and including a first line part and a first connection part contacting the first line part through a first contact hole overlapping one of the sub-layers.
