DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240118765 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with a sensor electrode layer that includes multiple touch electrode groups and contact electrodes of different sizes.
- The display device includes a substrate, a light emitting element layer, and a sensor electrode layer.
- The sensor electrode layer has multiple touch electrode groups extending along different directions.
- Each touch electrode group includes touch electrodes arranged in a specific pattern.
- Contact electrodes are connected to the touch electrodes within each group.
- The area of the first contact electrode is larger than the area of the second contact electrode.
Potential Applications
This technology could be used in touch screen displays, interactive kiosks, and other devices that require touch input functionality.
Problems Solved
This innovation helps improve the accuracy and sensitivity of touch input detection on display devices.
Benefits
The larger contact electrode area can enhance the responsiveness and precision of touch interactions on the display.
Potential Commercial Applications
Potential commercial applications of this technology include smartphones, tablets, laptops, and other consumer electronic devices.
Possible Prior Art
One possible prior art for this technology could be touch screen displays with multiple touch electrode groups, but without the specific arrangement and sizing of contact electrodes described in this patent application.
