  • Display device with capacitive touch detection
    Patent number: 10386955
    Abstract: A liquid crystal display device includes a panel unit and a driving unit driving the panel unit. The driving unit includes as operation modes a first mode in which a detection operation of a first external object is performed in units of a divided region obtained by dividing an entire surface of a touch region of the panel unit and a second mode in which a detection operation of a second external object is performed on the entire surface of the touch region of the panel unit. The first mode is a mode detecting, in units of the divided region of the panel unit, a contact position of the first external object with each divided region, and the second mode is a mode detecting, on the entire surface of the panel unit, whether or not the second external object approaches the entire surface.
    Type: Grant

  • Linear image sensor
    Patent number: 8059176
    Abstract: A linear image sensor with low noise and low power consumption comprises both high and low resolution analog shift registers for each photocell array. Noise in the output signals is decreased by driving either the low resolution analog shift register or the high resolution analog shift register depending on a required resolution. The power consumption of the linear image sensor is decreased because a charge detector receives charges from the high and low resolution analog shift registers.
