Display apparatus having temperature compensation function |
摘要 |
The invention provides a display apparatus having a temperature sensor and a step-up circuit generating a drive voltage of the display apparatus by stepping up a power source voltage. The temperature sensor provides temperature data indicative of the temperature of the display panel with a reduced measurement error without limiting the operation of the step-up circuit. To do so, in view of the fact that the step-up circuit has alternating active state in which the circuit is stepping up a source voltage to output a required step-up voltage and inactive state in which no stepping operation is made, the temperature sensor is adapted to obtain temperature data while the step-up circuit is inactive. The temperature data obtained is supplied to a temperature compensation means for changing the drive condition setting value that define the drive condition of the display panel to compensate for the temperature change.
