Capacitive touch sensing apparatus for electronic devices
A touch sensing apparatus for a touch panel has been granted a patent (Publication Number: US11995269B2). The apparatus includes touch sensing circuits and operation units in a one-to-one correspondence, with some circuits designated as to-sense touch sensing circuits and others as reference touch sensing circuits. Each touch sensing circuit corresponds to a touch sensitive cell and is responsible for transmitting touch excitation signals and receiving touch sensing signals. The operation units calculate a differential signal based on the output signals of the to-sense and reference touch sensing circuits, which is associated with capacitance differences between the two. The apparatus also includes digital processing units for further processing the signals into digital form for determining touch positions on the touch panel.
Furthermore, the touch sensing apparatus allows for customization by adjusting preset coefficients related to the area ratio between contact pads of touch electrodes. The touch excitation signal and touch reference signal are different signals, with the operation units multiplying the reference touch signal by the preset coefficient to obtain the differential signal. The patent also highlights the importance of the amplitude ratio between the two signals, which can be related to noise signal values or the area ratio of the touch sensitive cells. This innovative touch sensing apparatus offers a sophisticated solution for accurately detecting touch inputs on touch panels, enhancing user experience in electronic devices equipped with this technology.
