摘要： A liquid crystal display (LCD) apparatus includes: multiple differential amplifier stages each of which is operable to generate, according to a bias current and an input voltage, an output voltage having a magnitude and a slew rate that correspond respectively to the input voltage and a magnitude of the bias current, and serving as a data voltage of a corresponding pixel unit of an LCD panel; multiple current sources controllable to generate and provide a plurality of the bias currents to the differential amplifier stages, respectively; and a bias voltage generating unit connected electrically to the current sources in a current mirror configuration for generating an input bias current and controlling the current sources to generate the bias currents according to a latch pulse signal. The slew rate of the output voltage corresponds to a logic state of the input bias current.
