TOUCH PAD MODULE AND ELECTRONIC DEVICE USING THE SAME

摘要

A touch pad module includes: a touch pad, a sensor group, a touch pad controller IC and a touch pad controller IC (Integrated Circuit). The touch pad has a touch surface touchable by a user. The sensor group is mounted on a mount surface of the touch pad. The sensor group includes at least one of an acceleration sensor, a gyro sensor and a geomagnetic sensor. The touch pad controller IC is mounted on the mount surface of the touch pad configured to control the touch pad and includes a detector, a digital processor and a first interface. The detector generates digital data representing an electrical state of the touch pad. The digital processor generates coordinate data representing coordinates touched by the user based on the digital data. The first interface transmits data between the digital processor and the outside of the touch pad controller IC.

1. A touch pad module comprising:
a touch pad having a touch surface touchable by a user; a sensor group mounted on a mount surface of the touch pad in the opposite to the touch surface, the sensor group including at least one of an acceleration sensor, a gyro sensor and a geomagnetic sensor; a touch pad controller IC (Integrated Circuit) mounted on the mount surface of the touch pad and configured to control the touch pad, the touch pad controller IC including a detector configured to generate digital data representing an electrical state of the touch pad, a fifth interface connected to the sensors included in the sensor group via a fourth bus, a sixth interface connected to a CPU (Central Processing Unit) via a fifth bus, and a digital processor configured to control the sensor group through the fifth interface, acquire first data based on outputs of the sensors, control the detector, acquire second data representing a coordinate touched by the user based on the digital data, and transmit the first data and the second data to the CPU via the sixth interface.
