Abstract

A driving method of a display device is provided. In a first period, threshold voltages are simultaneously compensated for all first transistors which are provided in a plurality of pixels arranged in a matrix form with n rows and m columns. In a second period, turning switches are turned off, and image data is written to the first transistors in the plurality of pixels row-by-row. In a third period, all light-emitting elements are made to simultaneously emit light. n and m are each an integer larger than 1. Each of the first transistors is configured so that the image data is input to a control terminal, a first terminal is electrically connected to a power-source line, and a second terminal is electrically connected to the light-emitting element. The power-source line is supplied with a high-level potential in the first and third periods and a low-level potential in the second period.
