Frequency variable display apparatus

Abstract

A frequency variable display apparatus is provided. In the frequency variable display apparatus, one frame period comprises a vertical active period during which a data voltage is input to a subpixel and a vertical blank period which follows the vertical active period and during which the data voltage is not input to the subpixel. Also, in the one frame period with a frame frequency lower than a predetermined maximum frame frequency in a variable frame frequency range, a scan signal applied to the subpixel has one gate on period to turn on a first switch transistor connected between a data line and a driving transistor, and the sense signal applied to the subpixel has two or more gate on periods to turn on a second switch transistor connected between the driving transistor and a reference voltage line.
