As shown in FIG. 1 , this embodiment provides a display terminal, and the display terminal includes a first display unit 110 and a second display unit 120;

The front of the first display unit 110 is provided with an exposed first display screen;

The second display unit 120 includes a second display screen 121 and an accommodating cavity 122 for accommodating the second display screen 121;

The accommodating cavity 122 is located on the side and/or back of the first display unit 110 ;

The second display unit 120 corresponds to a hidden state and a revealed state;

In the hidden state, the second display screen 121 is located in the accommodating cavity 122;

In the exposed state, the second display screen 121 is at least partially located outside the accommodating cavity 122 .

The display terminal is a terminal capable of displaying images, specifically electronic equipment such as a mobile phone, an e-book, or a tablet computer, and the display terminal is preferably a mobile terminal.

The first display screen of the first display unit 110 may be a hard display screen, specifically, a common liquid crystal LCD display screen or an organic light emitting diode OLED display screen, etc., which are composed of glass as a support for the display screen. The first display screen can also be a flexible display screen; the first display screen is a display screen fixedly displayed on the surface of the display terminal. The flexible display screen can be, for example, a common plastic liquid crystal display screen or projection screen used as a support structure for the display screen.

The side of the first display unit 110 provided with the first display screen is the front of the first display unit; usually, the part of the first display screen exposed on the outer surface of the display terminal is the first display The display area of the screen; then the side of the first display unit 110 provided with the display area is the front of the first display unit 110 . The back of the first display unit 110 is the side opposite to the front; the side of the first display unit 110 is the side around the front of the first display unit 110 .

The second display screen 121 may be a screen such as a flexible liquid crystal display or a projection screen. The accommodating cavity 122 may be a hollow cavity formed by a casing. The accommodating cavity 122 can be located at the side of the first display unit 110 or at the back of the first display unit 110 , or partly at the side of the first display unit and another part at the first display unit 110 . The side of the display unit 110 .

The cavity of the accommodating cavity 122 can be integrated with the housing for installing the first display unit 110 as shown in FIG. such as a cylindrical shell).

In a specific implementation process, the first display unit 110 and the second display unit 120 may be two independent display structures, or two display parts corresponding to the same display structure; when the first display When the unit 110 and the second display unit 120 correspond to two display parts of the same display structure, the display part corresponding to the first display screen is fixedly exposed, while the display part corresponding to the second display screen is Can be revealed and hidden. Specifically, the display structure includes a large flexible display screen; the part corresponding to the first display screen is fixedly displayed on the surface of the display terminal, and the part corresponding to the second display screen is It can be hidden in the accommodating cavity or exposed outside the accommodating cavity.
