Original Abstract Submitted
a light emitting display apparatus includes a pixel having a pixel driving circuit and a light emitting device, and a gate driver supplying gate signals to the pixel driving circuit. the pixel driving circuit includes a switching transistor and a first light emitting transistor. the first light emitting transistor is connected between an anode of the light emitting device and a first node, and the switching transistor is connected between a data line in the light emitting display panel and the first node. during use, the gate driver turns on the first light emitting transistor m times per second (m is a natural number of 3 or more) and turns on the switching transistor s times smaller than m times and more than one time (s is a natural number of 2 or more) per second. one second is divided into a refresh period and an anode reset period.
