Specifically, the controller may control the electric signal loaded on the second display screen to be the first electric signal.
When the second display screen is loaded with different electric signals, the light transmittance can be different, when the second display screen is loaded with the first electric signal, the light transmittance of the second display screen can be the first light transmittance, and the first light transmittance is greater than a preset first light transmittance threshold value. When the luminousness of second display screen was first luminousness, the light that the light trap permeates can get into leading camera to make leading camera can gather the image accurately. At this time, the second display screen can be considered to be light-transmitting, and the second display screen does not normally display images, so that images collected by the front camera can be displayed on the first display screen.
When the controller receives an instruction for closing the front camera, the controller adjusts the second display screen in a second adjustment mode, specifically, the electric signal corresponding to the second adjustment mode is determined according to the stored corresponding relationship between different adjustment modes and the electric signal, the electric signal corresponding to the second adjustment mode is called a second electric signal, and the second display screen is adjusted through the second electric signal.
Specifically, the controller may control the electrical signal loaded on the second display screen to be the second electrical signal.
The light transmittance of the second display screen when the second electric signal is loaded is a second light transmittance, and the second light transmittance is smaller than a preset second light transmittance threshold value and can be considered as almost light-tight. The first transmittance threshold is greater than the second transmittance threshold. Because the second luminousness of second display screen is less, then can block the light that the light trap permeates and get into leading camera, and the second display screen that is loaded the second signal of telecommunication can regard as nearly opaque, and the second display screen is in normal display mode this moment, can carry out image display together with first display screen.
The first transmittance threshold may be 90% and the second transmittance threshold may be 10%.
In the implementation of the present invention, a first plane where the first display screen is located and a second plane where the second display screen is located may be the same plane, and for convenience of display, the first display screen and the second display screen may be physically an integrated display screen, the display screen is divided into regions, and the divided preset region is used as a region where the second display screen is located, where the preset region includes a region where a projection of the camera on the first plane is located.
When the second display screen is controlled, the electrical signal loaded on the preset area can be determined and controlled to adjust the light transmittance of the second display screen.
The second display screen and the first display screen may also be physically separated for design convenience.
The second display screen described above can change the Light transmittance, and the second display screen capable of changing the Light transmittance can be made of any molecular material of a zinc aluminum oxide ZAO thin film, a carbon nanotube, graphene, a silver nanowire, and the like, and can be correspondingly called a zinc aluminum oxide ZAO thin film screen, a carbon nanotube screen, a graphene screen, and a silver nanowire screen, and the second display screen can also be an Organic Light-Emitting Diode (OLED) screen, an Active Matrix Organic Light Emitting Diode (AMOLED) screen.
