The display state includes:
setting the display content of the display module to be "X", controlling the long axis direction of the liquid crystal in the liquid crystal layer 105 in the region corresponding to the "X" to be perpendicular to the first substrate 101 and the second substrate 102, when the external light reaches the first substrate 101, the first light in the first direction passes through the first substrate 101 and the liquid crystal layer 105 in the region corresponding to the "X" to reach the second substrate 102, and is reflected by the second substrate 102, so that the first light passes through the liquid crystal layer 105 in the region corresponding to the "X" and the first substrate 101 to complete the display of the "X", and the liquid crystal in the remaining regions can be deflected at a certain angle, so that the intensity of the first light in the remaining regions in the first direction is smaller than that in the region corresponding to the "X", or the light in the remaining regions is transmitted out, and forming transparent display so that the display module can display the X, and at the moment, the display module is in gray scale display.
Or controlling the deflection of the liquid crystal in the liquid crystal layer 105, so that the deflection degree of the liquid crystal corresponding to the X area is different from that of other areas, thereby achieving the purpose of gray scale display.
