  • Patent number: 9733748
    Abstract: A touch panel is disclosed herein. The touch panel includes a driving line, a gate line, a readout line, and a switching unit. The driving line is configured to transmit a driving signal. The gate line is configured to transmit a scan signal. The readout line forms a mutual capacitance with the gate line, and the mutual capacitance is configured to generate a first sensing signal in response to a driving signal according to a touch operation. The switching unit is electrically coupled to the gate line and the readout line, and configured to be selectively turned on to transmit the first sensing signal to the readout line according to the scan signal.

  • Patent number: 9547398
    Abstract: A substrate with touch function includes a plurality of scan lines and at least a touch device disposed thereon. The touch device includes at least a power line, at least a readout line, a light sensing circuit and a voltage divider circuit. The power line and the readout line are disposed on the substrate. The light sensing circuit is electrically coupled to a (N+1)th of the power lines, an Nth of the scan lines and an Nth of the readout lines, wherein N is an integer. The voltage divider circuit has an output terminal and is configured to output a first voltage to the light sensing circuit through the output terminal thereof according to a degree of illumination thereon or a degree of capacitance change. A display using the aforementioned substrate is also provided.

  • Patent number: 9116576
    Abstract: A photosensitive pixel circuit of a touch module including an output transistor and a light detection unit is provided. The output transistor receives a reference signal and provides a touch voltage controlled by a light detection voltage. The light detection unit is electrically connected to the output transistor, and receives a touch scan signal. The light detection unit detects an intensity of a light according to the touch scan signal so as to correspondingly provide the light detection voltage.

  • Patent number: 9035916
    Abstract: An optical touch display panel includes a plurality of light-sensing touch units and a position detecting circuit. Each light-sensing touch unit includes a light-sensing component, a storage capacitor, a signal reading component, and a charging component. The light-sensing component senses a light source to generate a sensing signal. The storage capacitor is connected electrically to the light-sensing component for storing the sensing signal. The signal reading component is connected electrically to the storage capacitor for reading a voltage of the storage capacitor to generate a reading signal. The charging signal is connected electrically to the storage capacitor for charging the storage capacitor to reset an electric charge record of the storage capacitor. The position detecting circuit is connected electrically to the light-sensing touch units for detecting a touch point on the optical touch display panel according to a reading signal output by each of the light-sensing touch units.
