  • Patent number: 8730211
    Abstract: In an exemplary optical touch circuit and a LCD device using the same, an optical sensing unit is turned on or off according to an irradiation light intensity and accordingly generates a first signal. A first signal readout unit is electrically coupled to the optical sensing unit and turned on or off according to a first operation timing sequence and accordingly outputs the first signal. A touch reference unit is for providing a reference voltage. A second signal readout unit is turned on or off according to a second operation timing sequence and accordingly outputs the reference voltage. The touch sensing unit is electrically coupled to the first and second signal readout units and uses a voltage difference between the first signal and the reference voltage as a basis to determine that whether the optical touch circuit is touched or not.

  • Patent number: 8698719
    Abstract: A displaying method for field sequential color displays using two color fields to produce a full color image is disclosed. The displaying method includes: providing a target full color image, displaying a first color field and displaying a second color field. The target full color image is formed by a first color image optical stimulus, a second color image optical stimulus and a third color image optical stimulus. The first color field displays the first color image optical stimulus and a first part of the third color image optical stimulus, while the second color field displays the second color image optical stimulus and a second part of the third color image optical stimulus, which compensates the shortage of the third color image optical stimulus in the first color field. The target full color image is generated by displaying the first and second color fields in sequence, so as to decrease the displaying frequency of field sequential color displays.
