  • Publication number: 20250165106
    Abstract: A sensor device includes first sensors, second sensors, and a sensor driver. The first sensors are arranged along a first direction, and the second sensors are arranged along a second direction. The sensor driver is configured to transmit driving signals to the first sensors through first sensor lines and to receive sensing signals from the second sensors through second sensor lines. During a first period, the sensor driver is configured to transmit the driving signals to a first group of sensors, and to transmit offset signals having a frequency that is equal to that of the driving signals and a phase that is different from that of the driving signals to a second group of sensors. During a second period, the sensor driver is configured to transmit the offset signals to the first group of sensors and to transmit the driving signals to the second group of sensors.

  • Patent number: 12008197
    Abstract: A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.
