When the photosensitive element array operates, the lattice liquid crystal control circuit controls the liquid crystal of the lattice liquid crystal layer in the lattice panel so as to change from a light-transmitting state to a light-shielding state.

The translucent state is a state in which light rays can be completely transmitted, and the light-shielded state is a state in which light rays cannot be transmitted or the transmittance of light rays is smaller than a predetermined value. Here, the predetermined value is a preset value.

When the photosensitive element array does not operate, the lattice liquid crystal layer in the lattice panel is in a translucent state, and when the photosensitive element array operates, the terminal is in a light-shielding state from the translucent state by the lattice liquid crystal control circuit. It is controlled to convert to, and the lattice liquid crystal layer is controlled to maintain this state.

The operating condition of the photosensitive element array is in the vertical direction to ensure that the terminal collects an image through the photosensitive element and the photosensitive element is not affected by light rays in a direction other than the vertical direction when collecting the image. Light rays in directions other than the above must be blocked, and therefore the latticed liquid crystal layer in the latticed liquid crystal panel must be maintained in a light-shielded state.

In the situation where the photosensitive element array does not operate, the terminal does not collect the image through the photosensitive element, and the image display panel must display the image as usual. At this time, the lattice liquid crystal layer in the lattice panel is in a light-shielded state. If so, the lattice liquid crystal layer must maintain a translucent state so as to shield the image displayed on the image display panel and therefore do not affect the display of the image when the photosensitive element does not operate.
