In this embodiment, the screen 11 is an LCD (Liquid Crystal Display), and includes an upper polarizer (not shown), a color filter substrate 110, a Liquid Crystal layer 111, a TFT (Thin Film Transistor) substrate 113, a lower polarizer (not shown), and a backlight module 115, which are sequentially disposed, where the backlight module 115 is configured to emit backlight, and the rotation direction of Liquid Crystal molecules in the Liquid Crystal layer 111 is controlled by changing signals and voltages of the Thin Film transistors, so as to control whether polarized light of each pixel point is emitted or not to achieve a Display purpose.
Referring to fig. 2, in the present embodiment, the aperture adjustment area 13 includes a first transparent substrate 131, a first transparent electrode layer 132, a liquid crystal layer 133, a second transparent electrode layer 134, and a second transparent substrate 135, which are sequentially disposed, where the first transparent electrode layer 132 and the second transparent electrode layer 134 are used to control the deflection direction of the liquid crystal in the liquid crystal layer 133 located in different aperture areas, so as to adjust the light transmission area of the aperture adjustment area 13, thereby obtaining different apertures. The aperture adjustment area 13 may be formed by a portion of an LCD, wherein the first transparent substrate 131 is a portion of a transparent substrate in the color filter substrate 110, the first transparent electrode layer 132 is a portion of an electrode layer on the color filter substrate 110, the liquid crystal layer 133 is a portion of a liquid crystal layer 111 of the LCD, the second transparent electrode layer 134 is a portion of an electrode layer on the TFT substrate 113, and the second transparent substrate 135 is a portion of a transparent substrate in the TFT substrate 113. On this basis, in order to ensure that the aperture adjusting area 13 reaches the maximum light incident amount, the parts of the upper polarizer, the color film and the lower polarizer of the LCD, which correspond to the aperture adjusting area 13, are hollowed out, meanwhile, the part of the backlight module 115, which corresponds to the aperture adjusting area 13, is hollowed out, and a silk-screen opening is left in the position of the LCD, which corresponds to the aperture adjusting area 13. Therefore, the aperture adjusting area 13 can be manufactured integrally and synchronously with the LCD, and the structure is simple and reliable. To reduce the overall thickness of the mobile terminal, the light incident side of the camera module 12 extends into the hollowed portion of the backlight module 115.

Alternatively, the liquid crystal layer 133 may be normally open by maintaining the liquid crystal corresponding to the central aperture region 136 in a light-transmissive deflected state by rubbing alignment, and at this time, the portions of the first transparent electrode layer 132 and the second transparent electrode layer 134 corresponding to the central aperture region 136 may be hollowed out.

Third embodiment
Fig. 6 is a flowchart illustrating a control method of a mobile terminal according to a third embodiment. Referring to fig. 6, the method for controlling a mobile terminal of the present embodiment includes:
in step 310, the light-transmitting area of the aperture adjusting area is adjusted to obtain the target aperture.
Referring to fig. 3, the apertures are arranged in different stages, the central aperture area is a fixed aperture, and different combinations of the peripheral aperture areas form apertures of different stages, for example, the first peripheral aperture area is opened, the second peripheral aperture area and the third peripheral aperture area are closed, corresponding to a first-stage aperture, the first peripheral aperture area and the second peripheral aperture area are opened, the third peripheral aperture area is closed, corresponding to a second-stage aperture, the first peripheral aperture area, the second peripheral aperture area and the third peripheral aperture area are all opened, corresponding to a third-stage aperture, when a photo is taken, the camera module is started, the light-transmitting area of the aperture adjustment area is adjusted to obtain a desired target aperture, which is, for example, the first-stage, the second-stage or the third-stage aperture, and the liquid crystal corresponding to the aperture area is controlled to deflect to a light-transmitting state according to the desired aperture, so that the corresponding aperture can be opened.
Referring to fig. 2, the aperture adjustment area includes a first transparent substrate, a first transparent electrode layer, a liquid crystal layer, a second transparent electrode layer and a second transparent substrate, which are sequentially disposed, the aperture adjustment area includes a central aperture area and at least one peripheral aperture area, the central aperture area corresponds to a central area of the camera module, the at least one peripheral aperture area is concentric with the central aperture area, and a light-transmitting area of the aperture adjustment area is adjusted to obtain a target aperture, which includes:

and adjusting the voltage of the parts of the first transparent electrode layer and the second transparent electrode layer, which are positioned in the aperture area to be adjusted, so that the liquid crystal in the liquid crystal layer, which is positioned in the aperture area to be adjusted, is deflected, and the target aperture is obtained.
The different apertures correspond to different light transmission states of the aperture areas, the aperture area to be adjusted is also an aperture area of which the current state is inconsistent with the target state, for example, when the first-gear aperture is adjusted to the second-gear aperture or the second-gear aperture is adjusted to the first-gear aperture, the second peripheral aperture area is an aperture area to be adjusted, when the second-gear aperture is adjusted to the third-gear aperture, the third peripheral aperture area is an aperture area to be adjusted, and when the third-gear aperture is adjusted to the first-gear aperture, the second peripheral aperture and the third peripheral aperture area are both aperture areas to be adjusted.
In the process of adjusting the voltage of the parts, located in the aperture area to be adjusted, of the first transparent electrode layer and the second transparent electrode layer and deflecting liquid crystals located in the aperture area to be adjusted in the liquid crystal layer, when the target state of the aperture area to be adjusted is open, the voltage of the parts, located in the aperture area to be adjusted, of the first transparent electrode layer and the second transparent electrode layer is adjusted, and the liquid crystals located in the aperture area to be adjusted in the liquid crystal layer are deflected to be in a light-permeable state; when the target state of the aperture area to be adjusted is closed, no voltage is supplied to the parts of the first transparent electrode layer and the second transparent electrode layer, which are positioned in the aperture area to be adjusted, so that liquid crystal in the liquid crystal layer, which is positioned in the aperture area to be adjusted, is in a non-light-permeable deflection state. Therefore, the deflection of the middle liquid crystal molecules is caused by controlling the voltage of the upper electrode and the lower electrode, and the size of the light inlet area of the camera module injected by an external light source is further controlled, so that the effect of the iris diaphragm can be realized.

When the aperture adjusting area adopts the electrochromic layer to realize the aperture adjusting function, the power-on state of the electrochromic layer corresponding to the aperture area is controlled according to the target aperture to obtain different apertures, wherein the aperture area in the power-off state is opaque to be closed, and the aperture area in the power-on state is transparent to be opened.
Before adjusting the light-transmitting area of the aperture adjustment zone to obtain the target aperture, the target aperture may be determined according to at least one of the following ways: determining a target aperture according to the operation of selecting the aperture; or, determining the target aperture according to the ambient brightness; or, the target aperture is determined according to the shooting distance.

Or, the aperture can be automatically adjusted according to the ambient brightness, and when the ambient brightness is larger, the aperture is adjusted to be smaller, otherwise, the aperture can be adjusted to be larger. Alternatively, the aperture may be automatically adjusted according to the distance between the mobile terminal and the shooting object, and the closer the distance, the smaller the aperture, and vice versa.
And step 320, controlling the camera module to shoot.
After the aperture is manually set or automatically adjusted according to the ambient brightness, the user changes the distance between the mobile terminal and the shooting object until the focusing is clear, and the shooting is performed by clicking, and then the mobile terminal can process the image through an ISP (image Signal processor) image processing technology and display the image. Or the user changes the distance between the mobile terminal and the shooting object, the mobile terminal automatically adjusts the aperture according to the distance until the focusing is clear, and after the user clicks to shoot, the mobile terminal can process the image through an ISP image processing technology and then display the image.
In the control method of the mobile terminal of the embodiment, after the light-transmitting area of the aperture adjusting area on the housing is adjusted to obtain the target aperture, the camera module is controlled to shoot. Through this kind of mode, this application can adjust the light ring when shooing, satisfies the focus demand of shooing far and near.
