  • Publication number: 20230273073
    Abstract: A temperature sensor includes a first selection circuit outputting one among temperature signals in response to a selection code. A reference voltage generator generates a reference voltage. A control circuit generates a control signal. A second selection circuit outputs the reference voltage and the temperature signal in response to the control signal indicating a voltage conversion condition is satisfied and outputs only the temperature signal in response to the control signal indicating the voltage conversion condition is not satisfied. A converter converts the reference voltage to a voltage digital code and the temperature signal to a temperature digital code in response to the control signal indicating the voltage conversion condition is satisfied and converts only the temperature signal to the temperature digital code in response to the control signal indicating the voltage conversion condition is not satisfied.

    Abstract: A display device includes a sensing circuit and a controller which selects a pixel row in a frame period. A vertical blank period of the frame period includes a sensing time in which the sensing circuit performs a sensing operation for the selected pixel row. The sensing circuit measures a first source voltage of a driving transistor of a pixel in the selected pixel row at a first time point of the sensing time, and measures a second source voltage of the driving transistor at a second time point of the sensing time. The controller calculates a threshold voltage parameter and a mobility parameter based on the first and second source voltages, predicts a saturated source voltage of the driving transistor based on the threshold voltage parameter and the mobility parameter, and calculates a threshold voltage of the driving transistor based on the saturated source voltage.
