Finally, the data of the display screen is sent to the IC, so that the IC drives the backlight circuit to realize display imaging.

Optionally, when the operation instruction is that the user slides the first screen left and right, it is determined whether the length range of the left and right sliding of the user is greater than a preset length range threshold; and the length range of the left and right sliding of the user is greater than a preset length. In the case of the range threshold, the photo preview screen displayed on the first screen is exchanged with the fill light screen displayed on the second screen.

Specifically, the preset length range threshold is a screen width of the second screen.

It should be noted that the screen display method of this embodiment can consider the preference of the user. For example, the user prefers to use the left screen or the right screen for shooting preview. In addition, the screen display method of the present embodiment can also consider the light intensity and the light change of the current captured scene. For example, in the shooting scene, when the light intensity of the left side of the current terminal is higher than the light intensity of the right side, it is necessary to fill the light from the right side. Therefore, it is necessary to adjust the screen used by the user. Through the above-described operation command of sliding left and right, the user can adjust the screen to be photographed in real time, so that the user's preference can be satisfied on the one hand, and the change of the surrounding environment can be timely adjusted.

The user using the terminal is taking a self-portrait while the current environment is moving from a bright street to a dim alley.

9 is a state diagram of a terminal under application scenario 1 in accordance with an embodiment of the present disclosure. As shown in FIG. 9, when the user performs a self-timer, it is first necessary to open the "camera" APP. At this time, the relevant processing unit in the terminal is regarded as the photographing instruction sent by the user for the operation. At the same time, the user adjusts the connection state of the first screen and the second screen to an expanded state of 180 degrees horizontally. The correlation processing unit detects that the distance between the Hall element in the terminal and the magnet in the terminal is greater than a preset distance, and the connection relationship corresponding to the value of the detected distance is an unfolded state of 180 degrees horizontally. Therefore, the relevant processing unit determines that the current screen connection state is an unfolded state of 180 degrees horizontally. After that, the first data for displaying the fill light screen is transmitted to the first screen located on the left while the second data for displaying the photograph preview screen is transmitted to the second screen located to the right.

After receiving the corresponding data, the first screen and the second screen respectively supply power to the IC and the backlight circuit in the screen, and then the IC combines the received data to drive the backlight circuit to display the first screen of the fill light screen and the photograph preview screen. Two screens.

At this point, the user finds that due to the walk from the bright street to the dim alley, the effect of the fill light screen currently used for fill light is not sufficient.

At the same time, the user wants to shoot the scenery on the right. Therefore, the positions of the first screen and the second screen are in an unfolded state at a certain angle (in the present case, 90 degrees as an example). At this time, the relevant processing unit detects that the distance between the Hall element in the terminal and the magnet in the terminal is greater than a preset distance, and the connection relationship corresponding to the value of detecting the distance is an unfolded state of the vertical 90, thus The correlation processing unit determines that the current screen connection state is an unfolded state of 90 degrees. After that, the first data for displaying the fill light screen is transmitted to the first screen located on the left while the second data for displaying the photograph preview screen is transmitted to the second screen located to the right.

After receiving the corresponding data, the first screen and the second screen respectively supply power to the IC and the backlight circuit in the screen, but the IC combines the received data to drive the backlight circuit to display the first screen of the fill light screen and the photo preview screen. Two screens.

In addition, the user wants to take the scenery on the right, but the system presets the shooting mode with the first screen on the left and the second screen on the right. The system preset shooting mode can not meet the user's use requirements. Therefore, in order to facilitate photographing, the user slides the left screen on the left side to the left with a finger. When the moving distance moves all the fill light screens of the first screen out of the first screen, the first screen and the second screen detect that the length range of the left and right sliding is greater than the moving threshold, therefore, the first screen will be the same as the first screen. The second screen exchanges the first data and the second data, that is, the first screen acquires the second data, and the second screen acquires the first data. Then, the two screens are respectively imaged according to the interactive screen data, that is, the original first screen (the second screen after the exchange) displays the photo preview screen, and the original second screen (the second screen after the exchange) will The fill light screen is displayed.
