FIELD: physics. ^ SUBSTANCE: display device 10 includes a light source 17 and a light source driving unit 31 which is adapted to drive the light source 17. The light source driving unit 31 is adapted to drive the light source 17 with brightness control. Said unit is adapted to generate a pulse width modulated signal using different levels of brightness variation. Brightness variation frequency is selected from different brightness variation frequencies in accordance with the mode of adjusting the display device 10. ^ EFFECT: preventing vibration of components of the device. ^ 9 cl, 16 dwg |
