The invention discloses a plasma flat light source driving method. A driving signal applied to a plasma flat light source adopts a periodic signal formed by N square-wave pulses which are provided with rapid rising edges and rapid falling edges with frequency of 10-80KHZ and M low-level signals in a spacing way. The square-wave pulses are provided with the rapid rising edges and the falling edges. The plasma flat light source discharges only at the rising edges and the falling edges of the square-wave pulses and does not discharge at low levels. N is less than 5, M is less than 5 and N is greater than or equal to M. In order to improve light emission efficiency of the plasma flat light source, the invention brings forward the driving waveform adopting the mode that multiple high-level square-wave pulses and the low-level signals are arranged in the spacing way under the premise that the square-wave pulses are provided with steep rising edges so that the plasma flat light source can discharge intermittently and can emit light normally. Therefore, discharging maintenance time is reduced, electric heat loss can be greatly reduced, heat amount of a screen is reduced and light emission efficiency of the plasma flat light source is enhanced.
