Claim 15:
16. A display apparatus comprising:
a display panel comprising a pixel, the pixel comprising a switching element of a first type and a switching element of a second type different from the first type; and
a display panel driver which drives the display panel,
wherein the display panel driver is configured to drive the switching element of the first type in a high driving frequency and the switching element of the second type in the high driving frequency in a first mode,
wherein the display panel driver is configured to drive at least one of the switching element of the first type and the switching element of the second type in the low driving frequency in a second mode, and
wherein the display panel driver is configured to count a duration of the second mode, and
wherein when the duration of the second mode is greater than a reference time, a threshold shift preventing mode operates during the duration of the second mode, and
wherein, in the threshold shift preventing mode, a driving signal applied to at least one of the switching element of the first type and the switching element of the second type is briefly changed which prevents a shift of a threshold voltage of the at least one of the switching element of the first type and the switching element of the second type,
wherein after changing the driving signal to prevent the shift in the threshold voltage, the low driving frequency having a same low driving frequency as before changing from the second mode is resumed, and
wherein in the threshold shift preventing mode, a compensation frame associated with the driving signal is only added going from a lower driving frequency to a higher driving frequency.
