A dual screen display device (10), a dual screen display method, and electronic equipment. The dual screen display device (10) comprises: a first display unit (101) and a second display unit (102), a light receiving surface of the first display unit (101) being arranged opposite to a light receiving surface of the second display unit (102); a backlight module unit (107), arranged between the light receiving surface of the first display unit (101) and the light receiving surface of the second display unit (102); a light source unit, used for emitting illumination light to the backlight module unit (107); and a first polarization filtering unit (108) and a second polarization filtering unit (109), arranged on the light receiving surface of the first display unit (101) and the light receiving surface of the second display unit (102) respectively. The polarization direction of the first polarization filtering unit (108) is orthogonal to the polarization direction of the second polarization filtering unit (109). The illumination light is deflected to the first display unit (101) and the second display unit (102) through the backlight module unit (107), and illuminates the first display unit (101) and the second display unit (102) after passing through the first polarization filtering unit (108) and the second polarization filtering unit (109).
