Abstract: A light-emitting diode display device and a light-emission control method thereof are provided. The light-emitting diode display device includes a timing controller, multiple display pixels, and a scanning circuit. The display pixels form multiple display rows. The scanning circuit generates multiple scan signals and multiple light-emission signals that respectively drive the display rows. During a first data-writing time period of a first frame period, the timing controller provides multiple writing data to be respectively written into the display rows. During a light-emitting time period, the scanning circuit drives each of the light-emission signals to generate multiple pulses periodically according to a set period to drive the corresponding display rows. The light-emitting time period is after the first data-writing time period and before a second data-writing time period of a second frame period ends.
