  • Publication number: 20080062100
    Abstract: In a voltage generating circuit and a display apparatus, a driving voltage generator receives an input voltage to output a first driving voltage and a second driving voltage that is inversely proportional to a temperature in response to a feedback voltage. A temperature compensator generates the feedback voltage as a function of the temperature and the second driving voltage and applies it to the driving voltage generator. A gate-on voltage generator pumps the second driving voltage to generate a gate-on voltage, and a gamma voltage generator outputs a plurality of gamma voltages, each having a different voltage level that is disposed between the first driving voltage and a ground voltage. The gate-on voltage, which is inversely proportional to the temperature, is applied to the gate driver, and the gamma voltages, which are maintained at constant levels, prevent the response speed of the display apparatus from varying with temperature.
