Realtek Semiconductor had two patents in big data during Q1 2024. Realtek Semiconductor Corp has developed a method and device for recognizing and processing the waterproof state of a capacitive touch screen. This technology can differentiate between water-affected and water-free regions on the screen, allowing touch operations in the water-free region even when the water-affected region is present. The method involves scanning the screen, determining waterproof and finger-touch thresholds, and performing corresponding processes based on the data obtained.

Application: Waterproof-state recognition and processing method and device applicable to capacitive touch screen (Patent ID: US20240086006A1)

The patent filed by Realtek Semiconductor Corp. describes a method and device for recognizing and processing the waterproof state of a capacitive touch screen. The method involves scanning the screen to collect data from multiple channels, determining if any data reaches a waterproof threshold, and executing different processes based on the data reaching specific thresholds. These processes include a waterproof-state process, a finger-touch-state process, and an idle-state process, depending on the data collected.

The device outlined in the patent includes a channel scanning circuit and a data processing circuit that work together to determine the state of the touch screen based on the collected data. The device can differentiate between water-affected and water-free regions on the screen, allowing touch operations in unaffected areas even when water is present. The device's operations include marking and quarantining water-affected channels, periodic scanning to update data, and transitioning between different states based on the data collected. Overall, the method and device aim to improve the functionality and usability of capacitive touch screens in the presence of water or other contaminants.
