DISPLAY PANEL AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240241542 titled 'DISPLAY PANEL AND DISPLAY DEVICE

The abstract of the patent application describes a display panel with a base substrate that includes a display region and a fan-out region, which is positioned between the display region and a chip. The fan-out region contains multiple data wires/touch wires that electrically connect data lines/touch signal lines with the chip. Some of the data wires are in a first conductive layer, while the rest are in a second conductive layer. Similarly, some of the touch wires are in either the first or second conductive layer, with the remainder in a third conductive layer. The wire pitch in each layer varies, with the first and second wire pitches being smaller than the third wire pitch.

• The display panel features a base substrate with a display region and a fan-out region.
• Data wires and touch wires in the fan-out region connect data lines and touch signal lines with the chip.
• Data wires are split between a first and second conductive layer, while touch wires are divided between the first, second, and third conductive layers.
• The wire pitch in each layer differs, with the first and second wire pitches being smaller than the third wire pitch.
• This design optimizes the electrical connections within the display panel.

Potential Applications: - This technology can be used in various types of display panels, such as LCDs and OLEDs. - It can also be applied in touch screen devices, improving their performance and reliability.

Problems Solved: - Efficiently connecting data and touch signal lines with the chip in a display panel. - Optimizing the layout of wires to enhance electrical performance.

Benefits: - Improved functionality and reliability of display panels. - Enhanced performance of touch screen devices. - Cost-effective manufacturing process.

Commercial Applications: Title: Advanced Display Panel Technology for Enhanced Performance in Consumer Electronics This technology can be utilized in the production of smartphones, tablets, laptops, and other consumer electronic devices with display screens. It can improve the overall user experience by providing more reliable and efficient display panels.

Questions about Display Panel Technology: 1. How does the wire pitch variation in different conductive layers impact the performance of the display panel? 2. What are the specific advantages of having touch wires distributed across multiple conductive layers?
