  • Publication number: 20220375400
    Abstract: A display device includes a display panel having first and second display areas. A data driver provides data and bias voltages to data lines. A timing controller controls the data driver and a scan driver based on at least two operation modes. The first mode drives the first and second display areas at a normal frequency, and the second mode drives the first display area at a first frequency substantially equal to or lower than the normal frequency and the second display area at a second frequency lower than the first frequency. The second mode includes an active frame to write a reference voltage to display a black image in the second display area, and blank frames to maintain the reference voltage and apply the bias voltage to the pixels in the second display area. The data driver varies the bias voltage in the blank frames.
