  • Publication number: 20080018569
    Abstract: An organic light emitting diode display device includes; a display panel including a pixel connected to a gate line and a data line, gate and data driving circuits which drive the gate and data lines, respectively, at least one temperature sensor disposed on the display panel which senses a temperature of the display panel, a sensor driving unit which converts a temperature signal supplied from the temperature sensor into a digital temperature signal, a timing controller which supplies the gate driving circuit with a control signal, supplies the data driving circuit with a control signal and a data signal, and generates a gamma reference voltage control signal according to the digital temperature signal, and a digital to analog converter which generates a gamma reference voltage which varies according to the gamma reference voltage control signal and supplies it to the data driving circuit.
