A liquid crystal display apparatus includes an LCD panel assembly. A backlight assembly includes a light source that irradiates the LCD panel assembly. A light-sensing part generates a detection signal corresponding to a quantity of the light. A reference signal-generating part generates a reference signal corresponding to a reference quantity of the light. A control signal-generating part compares the detection signal with the reference signal to generate a control signal. A backlight assembly-controlling part controls the luminance of the light source in accordance with the control signal.

A liquid crystal display (LCD) which includes a liquid crystal panel and a temperature-measurement apparatus. The temperature-measurement apparatus includes a temperature sensor which includes a variable-resistance element having a resistance that varies according to the temperature of the liquid crystal panel and a fixed-resistance element connected in series to the variable-resistance element, divides a first input voltage, and outputs a first temperature-dependent voltage that varies according to a temperature of the liquid crystal panel. A voltage divider which divides a second input voltage and outputs a reference voltage is provided. A differential amplifier receives at a first input the first temperature-dependent voltage and receives at a second input the reference voltage and amplifies a difference between the first temperature-dependent voltage and the reference voltage, and provides at an output a second temperature-dependent voltage.

A display apparatus that includes a controller, a gate driver, a data driver, and a gamma voltage generator is presented. The controller generates image data and a data clock to drive a display unit based on original data and an original control signal received from an exterior. The gate driver provides an image data signal to a data interconnection provided in the display unit. The data driver provides a gate signal to a gate interconnection provided in the display unit. The gamma voltage generator generates gamma voltages serving as a reference in response to the data driver providing the gate signal to the display unit. The gamma voltage generator selectively outputs sub-reference voltages, which are divided from an external reference voltage, and a specific voltage, which is generated from the gamma voltage generator, as the gamma voltages.
