  • Patent number: 11506537
    Abstract: An optical sensing circuit including a capacitor, a light sensing unit, a compensation unit, and a switching element is provided. The light sensing unit, the compensation unit, and the switching element are electrically connected to the capacitor. The light sensing unit senses the light of a first color. The compensation unit senses the light of a second color complementary to the first color. When a light illuminates the light sensing unit and the compensation unit, a first light component of the light corresponding to the first color causes the light sensing unit to generate a first current, and a second light component of the light corresponding to the second color causes the compensation unit to generate a second current, which reduces the amount of the charging or the discharging current when the first current charges or discharges the capacitor whose voltage is read as information for determining light color.

  • Patent number: 11041761
    Abstract: An optical sensing circuit includes a capacitor, and a light sensing unit, a compensation unit, and a switching element coupled to the capacitor. The light sensing unit includes a first light sensing transistor for sensing a first color. The compensation unit includes a second light sensing transistor for sensing a second color. The spectra of the second color and the first color do not overlap each other. When the light illuminates, the light sensing unit generates a first current and the compensation unit generates a second current. The second current reduces the magnitude of the charging or discharging current when the capacitor is charged or discharged by the first current. When the switching element turned on, the voltage of the capacitor is read to determine the color of the light. The voltage level of the gate of the first or second light sensing transistor is adjustable.
