Electrostatic Capacitance-Type Sensor-Equipped Display Device and Method of Driving the Same Patent Filed and Published Online

A patent titled "Electrostatic Capacitance-Type Sensor-Equipped Display Device and Method of Driving the Same" has been filed by inventors Ishizaki, Koji, Kurasawa, Hayato, and Noguchi, Koji, and published online on October 14, 2025. The patent, filed on November 14, 2023, is assigned to Magnolia White Corporation (Tokyo, Japan) and has the patent number 12443318.

The patent describes an electrostatic capacitance-type sensor-equipped display device that can detect data input from a display surface side using input means, such as a pen or a human body. The display device can perform single-touch detection and can detect position information of a location touched by the finger. The device includes a substrate, a plurality of gate lines, a plurality of source lines, a plurality of TFTs, a plurality of pixel electrodes, a plurality of sensor electrodes, and insulation layers. The claims supplied by the inventors detail the structure and operation of the display device and method of driving it.
