Title: OPTICAL SENSING DEVICE, SEMICONDUCTOR DEVICE CONTAINING THE SAME, AND METHOD FOR DRIVING THE SAME
Abstract:
An optical sensing device, includes: a storage circuitry (Cs) being coupled to a charging circuitry, a photosensitive circuitry (T1), and a voltage- readout circuitry (T2), the storage circuitry (Cs) storing a voltage value; the charging circuitry being coupled to the storage circuitry (Cs) for charging the storage circuitry (Cs); the photosensitive circuitry (T1) being connected to a first terminal for discharging the storage circuitry (Cs) to the first terminal; and the voltage-readout circuitry (T2) being connected to the storage circuitry (Cs), for reading the voltage value of the storage circuitry (Cs).
