Patent Description:
At present, an aperture of a camera of a smart phone is fixed. Regardless of a photography scene, the aperture is fixed and cannot be adjusted. As a result, the photography imaging effect of the smart phone is single, the color is not bright enough, and the user experience is reduced. Further, a variable aperture is designed with a lens in the related art, and is mainly used for a professional camera, such as a single-lens reflex camera or a miniature single-lens reflex camera. The aperture has a mechanical structure, which requires a motor to drive the aperture to change or control the aperture by manual control.

A display module <NUM> according to an embodiment of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in <FIG>, the display module <NUM> according to this embodiment of the present application includes a first polarizer <NUM>, a color film layer <NUM>, a substrate <NUM>, a second polarizer <NUM>, and a backlight module <NUM>, which are stacked in sequence.

Specifically, the first polarizer <NUM> is provided with a first light-transmitting hole <NUM> penetrating in a thickness direction thereof. The color film layer <NUM> is provided with a light-transmitting region in positional correspondence with the first light-transmitting hole <NUM>. A control electrode <NUM> is provided in the light-transmitting region. The substrate <NUM> is provided with a liquid crystal display region <NUM> and an aperture adjustment region <NUM>. The position of the aperture adjustment region <NUM> corresponds to the position of the first light-transmitting hole <NUM>. The liquid crystal display region <NUM> is spaced apart from the aperture adjustment region <NUM>. The aperture adjustment region <NUM> is filled with guest host liquid crystals. A material of liquid crystals located in the liquid crystal display region <NUM> is different from a material of liquid crystals located in the aperture adjustment region <NUM>. The substrate <NUM> has a driving circuit. The driving circuit is connected to the control electrode <NUM>. The driving circuit drives the guest host liquid crystals to deflect so as to adjust an aperture.

In other words, as shown in <FIG>, the display module <NUM> according to this embodiment of the present application mainly includes a first polarizer <NUM>, a color film layer <NUM>, a substrate <NUM>, a second polarizer <NUM>, and a backlight module <NUM>. The first polarizer <NUM>, the color film layer <NUM>, the substrate <NUM>, the second polarizer <NUM>, and the backlight module <NUM> are stacked in sequence. The first polarizer <NUM> is provided with a first light-transmitting hole <NUM>. The first light-transmitting hole <NUM> penetrates in a thickness direction of the first polarizer <NUM>. Light can directly enter the color film layer <NUM> through the first light-transmitting hole <NUM>, thereby effectively reducing the attenuation of the light and improving the light transmittance. The color film layer <NUM> is provided with a light-transmitting region. The light-transmitting region corresponds to the position of the first light-transmitting hole <NUM>. A control electrode <NUM> is provided in the light-transmitting region. A liquid crystal display region <NUM> and an aperture adjustment region <NUM> are spaced apart on the substrate <NUM>. The position where the aperture adjustment region <NUM> is provided corresponds to the position where the first light-transmitting hole <NUM> is provided and the position where the light-transmitting region is provided.

As shown in <FIG>, the aperture adjustment region <NUM> is filled with guest host liquid crystals (GH-LCD). A material of liquid crystals located in the liquid crystal display region <NUM> is different from a material of liquid crystals located in the aperture adjustment region <NUM>. The guest host liquid crystals and the liquid crystal display region <NUM> are on the same layer and share a driving circuit of a liquid crystal panel to realize aperture control. Certainly, in the present application, other types of liquid crystals capable of realizing similar principles of the guest host liquid crystal also fall within the scope of protection of the present application and are not specifically limited in the present application. A driving circuit is provided on the substrate <NUM>. The driving circuit can be connected to the control electrode <NUM> of the color film layer <NUM>. The driving circuit can transmit a driving signal to the control electrode <NUM>. After receiving the driving signal, the control electrode <NUM> can release a charge-discharge voltage corresponding to the driving signal to drive the guest host liquid crystals to deflect.

Light is transmitted from the first light-transmitting hole <NUM> and the light-transmitting region to the aperture adjustment region <NUM> in sequence. Different driving signals are emitted by the driving circuit. The control electrode <NUM> can release different charge-discharge voltages. The guest host liquid crystals at different positions in the aperture adjustment region <NUM> may be deflected differently to change the light transmittance, thereby realizing the automatic adjustment of the aperture. It will be understood by a person skilled in the art that the second polarizer <NUM> is provided with a second light-transmitting hole <NUM> penetrating in a thickness direction thereof. The backlight module <NUM> is provided with a third light-transmitting hole <NUM> penetrating in a thickness direction thereof, and the third light-transmitting hole <NUM> is coaxial with the first light-transmitting hole <NUM> and the second light-transmitting hole <NUM>. A backlight side of the backlight module <NUM> faces the camera module <NUM>, and the third light-transmitting hole <NUM> corresponds to the camera module <NUM>. Light is transmitted into the camera module <NUM> from the first light-transmitting hole <NUM>, the light-transmitting region, the aperture adjustment region <NUM>, the second light-transmitting hole <NUM>, and the third light-transmitting hole <NUM> in sequence. The guest host liquid crystals at different positions may be deflected differently to change the light transmittance, thereby realizing the automatic adjustment of the aperture.

It is to be noted that the aperture is an apparatus for controlling the amount of light passing through and entering a photosensitive surface of a body, which is usually provided in a lens. Usually, the size of the aperture is represented by F, and the formula for calculating the size of the aperture is: F = focal length of lens / effective aperture of lens. From different photography scenes, different photography experiences may be obtained by using different values of F. However, it is impossible to change the diameter of the lens at will for the manufactured lens, but the effect of controlling the light throughput of the lens can be achieved by adding a polygonal or circular aperture grating with variable area inside the lens. When photographing, a large aperture may be used for portrait photography, thus achieving a good background blurring effect. When making a long shot, the aperture can be reduced to achieve wide angle, large depth of field, clear foreground and background.

As will be known to a person skilled in the art, a guest host effect is to dissolve a dichroic dye with different absorption of visible light in a major axis direction and a minor axis direction as a guest in a liquid crystal host aligned directionally. The dichroic dye will be aligned with liquid crystal molecules in the same direction accordingly. When the alignment of the liquid crystal molecules as the host changes under the action of an electric field, the alignment direction of dichroic dye molecules will also change. That is, the absorption of the dichroic dye to incident light will also change. The display module <NUM> of the present application emits different driving signals to the control electrode <NUM> through the driving circuit. After receiving the different driving signals, the control electrode <NUM> can release charge-discharge voltages corresponding to the driving signals to drive the deflection of the guest host liquid crystals at different positions, so as to change the light transmittance.

In the related art, although the light transmittance is also improved by digging holes in polarizing regions corresponding to the first polarizer <NUM> and the second polarizer <NUM>, only when the liquid crystal display region <NUM> and the aperture adjustment region are made of common liquid crystal materials, it is necessary to add upper and lower polarizers in polarizing directions perpendicular to each other on an aperture region to realize optical path control. However, the transmittance of each polarizer will be reduced by <NUM>%, and the light transmittance is greatly limited. Therefore, it is impossible to automatically control the aperture and make the imaging clearer. The aperture adjustment region <NUM> of the display module <NUM> of the present application uses the guest host liquid crystal. Since the liquid crystal display has a special light valve property, the light valve effect can be achieved without a polarizer.

In the display module <NUM> of the present application, the aperture adjustment region <NUM> is inserted into the normal liquid crystal display region <NUM>, and the aperture adjustment region <NUM> is filled with the guest host liquid crystals. By driving the deflection of the guest host liquid crystals at different positions, the light transmittance is changed, and the effect of a physical aperture is achieved. Compared with the physical aperture, the aperture of the present application not only has a smaller volume and can be provided in some electronic products with smaller accommodating space, but also is simpler and more intelligent to adjust than traditional mechanical aperture adjustment, which is convenient for users to operate.

The display module <NUM> of the present application may be applied to a camera of a mobile phone, the aperture of the camera of the mobile phone is adjustable, and multiple frames of images may be obtained as original image data during photography. The focal length corresponding to different aperture values changes, and different details of the same picture (adjust the depth of field) may be acquired. Further, with a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of mobile phone users.

Therefore, the aperture adjustment region <NUM> is filled with guest host liquid crystals, the first light-transmitting hole <NUM> is provided in the first polarizer <NUM>, and light can be directly irradiated on the guest host liquid crystals. With the light valve characteristics of the guest host liquid crystals, the driving circuit and the control electrode <NUM> can drive the guest host liquid crystals at different positions to deflect, thereby changing the transmittance of light entering the camera module. The display module <NUM> of the present application can achieve the effect of variable aperture while ensuring the light transmittance, and has the advantages of small aperture volume and high aperture adjustability. During photography, the display module <NUM> of the present application can acquire different details of the same picture by adjusting the aperture. With a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of users.

According to one embodiment of the present invention, an orthographic projection area of the aperture adjustment region <NUM> on the substrate <NUM> is not smaller than an orthographic projection area of the first light-transmitting hole <NUM> in the substrate <NUM>.

That is, as shown in <FIG>, the region where the aperture adjustment region <NUM> is provided on the substrate <NUM> corresponds to the position where the first light-transmitting hole <NUM> is provided in the first polarizer <NUM>. The orthographic projection area of the aperture adjustment region <NUM> on the substrate <NUM> may be equal to or greater than the orthographic projection area of the first light-transmitting hole <NUM> in the substrate <NUM>, so as to ensure that light entering from the first light-transmitting hole <NUM> can be fully irradiated on the aperture adjustment region <NUM> without light wasting. The area of the first light-transmitting hole <NUM> needs to be smaller than or equal to the area of the light-transmitting region, the aperture adjustment region <NUM>, the second light-transmitting hole <NUM>, and the third light-transmitting hole <NUM>. When light is transmitted into the camera module <NUM> from the first light-transmitting hole <NUM>, the light-transmitting region, the aperture adjustment region <NUM>, the second light-transmitting hole <NUM>, and the third light-transmitting hole <NUM> in sequence, the guest host liquid crystals may be deflected differently to change the light transmittance of all light passing through the first light-transmitting hole <NUM>, thereby realizing the automatic adjustment of the aperture.

In some specific implementations of the present invention, the display module <NUM> further includes a liquid crystal retaining wall <NUM>. The liquid crystal retaining wall <NUM> is a closed annular retaining wall. The inside region defined by the liquid crystal retaining wall <NUM> is the aperture adjustment region <NUM>. The region outside the liquid crystal retaining wall <NUM> is the liquid crystal display region <NUM>. The liquid crystal display region <NUM> is separated from the aperture adjustment region <NUM> through the liquid crystal retaining wall <NUM>.

That is, as shown in <FIG>, the display module <NUM> is further provided with a liquid crystal retaining wall <NUM>. The liquid crystal retaining wall <NUM> is a closed annular retaining wall. The liquid crystal retaining wall <NUM> is provided between the aperture adjustment region <NUM> and the liquid crystal display region <NUM>. The aperture adjustment region <NUM> is located inside the liquid crystal retaining wall <NUM>. The liquid crystal display region <NUM> is located outside the liquid crystal retaining wall <NUM>. By providing the liquid crystal retaining wall <NUM> between the aperture adjustment region <NUM> and the liquid crystal display region <NUM>, it is possible to separate the guest host liquid crystals located in the aperture adjustment region <NUM> from the liquid crystals located in the liquid crystal display region <NUM>, thereby avoiding affecting the light transmittance to the aperture adjustment region <NUM>.

According to one embodiment of the present invention, the guest host liquid crystals located in the liquid crystal retaining wall <NUM> is sealed with a sealant.

Specifically, as shown in <FIG>, the guest host liquid crystals may be injected into the set aperture adjustment region <NUM> on the substrate <NUM>, and then the guest host liquid crystals are sealed with a sealant.

The driving circuit can control each aperture electrode to release the corresponding charge-discharge voltage, whereby electric fields at different positions in the aperture adjustment region <NUM> change, so as to adjust the deflection of the guest host liquid crystals at different positions in the aperture adjustment region <NUM> and realize the adjustment of light transmittance.

In some specific implementations of the present invention, each aperture electrode is a closed-loop electrode, and the plurality of aperture electrodes are disposed coaxially.

Specifically, as shown in <FIG>, each aperture electrode may be a closed-loop electrode, and the shape of the aperture electrode may be a closed pattern such as circle, square, or an irregular shape. The shapes of the plurality of aperture electrodes may be shapes corresponding to the first light-transmitting hole <NUM> and the light-transmitting region. Each aperture electrode is controllable independently, and each aperture electrode may be independently charged and discharged. The guest host liquid crystals located in the aperture adjustment region <NUM> may form a guest host liquid crystal change region with a corresponding shape according to the shape of the aperture electrode. The plurality of aperture electrodes are disposed coaxially and at intervals. When the aperture electrodes are circular, the plurality of aperture electrodes are disposed coaxially. By adjusting different aperture electrodes, the guest host liquid crystals in different regions are deflected to change the light transmittance and realize the adjustment of the aperture. The aperture electrode may also be adjusted by different arrangements and combinations, whereby the guest host liquid crystal in the corresponding annular region is deflected, and the effect of the annular aperture can be achieved. That is, by changing the shape of the aperture electrode, light with different shapes and areas may pass, thus achieving a certain filter effect.

According to one embodiment of the present invention, each aperture electrode is an indium tin oxide electrode. Indium tin oxide is a transparent conductor, which can be used in a coating process. The conductive electrode function of the aperture electrode can be realized, and light will not be blocked. The light can enter the aperture adjustment region <NUM> from the light-transmitting region.

In a word, the first light-transmitting hole <NUM> and the second light-transmitting hole <NUM> are provided in the first polarizer <NUM> and the second polarizer of the display module <NUM> according to this embodiment of the present invention, thus improving the light transmittance. The aperture adjustment region <NUM> is filled with the guest host liquid crystals, and the guest host liquid crystals at different positions can be driven to deflect through the driving circuit and the plurality of aperture electrodes by utilizing the characteristics of the guest host liquid crystals. The display module <NUM> of the present application can achieve a variable aperture while ensuring the light transmittance, and achieve the same effect as the physical aperture. The display module <NUM> of the present application can acquire different details of the same picture by adjusting the aperture. With a digital image processing technology, images with clear edges and bright colors can be obtained. Different filter effects can be achieved by providing aperture electrodes with different shapes and adjusting the aperture, thus effectively improving the photography experience of users.

In a second aspect of the present application, an electronic device is provided. The electronic device according to this embodiment of the present invention includes a display module <NUM> and a camera module <NUM> in the foregoing embodiment. The camera module <NUM> is provided on the side of the display module <NUM> close to a backlight module <NUM>, and a viewfinder window of the camera module <NUM> corresponds to an aperture adjustment region <NUM> of the display module <NUM>, so as to photograph according to an aperture adjusted by the aperture adjustment region <NUM>.

That is, the camera module <NUM> is provided on the backlight module <NUM> of the display module <NUM>, and the camera module <NUM> has a viewfinder window. That is, the display module <NUM> is located on a light-entering side of the camera module <NUM>. The position where the viewfinder window is provided corresponds to the position where the aperture adjustment region <NUM> of the display module <NUM> is provided. By adjusting the aperture adjustment region <NUM>, the amount of light finally reached in the camera module <NUM> can be controlled.

Specifically, the display module <NUM> mainly includes a first polarizer <NUM>, a color film layer <NUM>, a substrate <NUM>, a second polarizer <NUM>, and a backlight module <NUM>. The first polarizer <NUM>, the color film layer <NUM>, the substrate <NUM>, the second polarizer <NUM>, and the backlight module <NUM> are stacked in sequence. The first polarizer <NUM> is provided with a first light-transmitting hole <NUM>. The first light-transmitting hole <NUM> penetrates in a thickness direction of the first polarizer <NUM>. Light can directly enter the color film layer <NUM> through the first light-transmitting hole <NUM>, thereby effectively reducing the attenuation of the light and improving the light transmittance. The color film layer <NUM> is provided with a light-transmitting region. The light-transmitting region is in positional correspondence with the first light-transmitting hole <NUM>. A control electrode <NUM> is provided in the light-transmitting region.

A liquid crystal display region <NUM> and an aperture adjustment region <NUM> are spaced apart on the substrate <NUM>. The position where the aperture adjustment region <NUM> is provided corresponds to the position where the first light-transmitting hole <NUM> is provided and the position where the light-transmitting region is provided. The second polarizer <NUM> is provided with a second light-transmitting hole <NUM> penetrating in a thickness direction thereof. The backlight module <NUM> is provided with a third light-transmitting hole <NUM> penetrating in a thickness direction thereof, and the third light-transmitting hole <NUM> is coaxial with the first light-transmitting hole <NUM> and the second light-transmitting hole <NUM>. A backlight side of the backlight module <NUM> faces the camera module <NUM>, and the third light-transmitting hole <NUM> corresponds to the camera module <NUM>.

In the present application, the aperture adjustment region <NUM> is inserted into the normal liquid crystal display region <NUM>, and the aperture adjustment region <NUM> is filled with the guest host liquid crystals. By driving the deflection of the guest host liquid crystals at different positions, the light transmittance is changed, and the effect of a physical aperture is achieved. Light is transmitted into the camera module <NUM> from the first light-transmitting hole <NUM>, the light-transmitting region, the aperture adjustment region <NUM>, the second light-transmitting hole <NUM>, and the third light-transmitting hole <NUM> in sequence. The driving circuit can control each aperture electrode to release the corresponding charge-discharge voltage, whereby electric fields at different positions in the aperture adjustment region <NUM> change, so as to adjust the deflection of the guest host liquid crystals at different positions in the aperture adjustment region <NUM>. The guest host liquid crystals at different positions are deflected differently to change the light transmittance, thereby realizing the automatic adjustment of the aperture.

The viewfinder window of the camera module <NUM> corresponds to the aperture adjustment region <NUM> of the display module <NUM>. By adjusting the aperture adjustment region <NUM>, the amount of light finally reached in the camera module <NUM> can be controlled. Then the camera module <NUM> acquires different details of the same picture according to actual photography requirements based on focal lengths corresponding to different aperture values of the adjusted aperture to obtain images with bright colors, thus effectively improving the photography experience of users.

In some specific implementations of the present application, the orthographic projection area of the aperture adjustment region <NUM> on the camera module <NUM> is not smaller than the area of the viewfinder window of the camera module <NUM>.

As shown in <FIG>, the region where the aperture adjustment region <NUM> is provided on the substrate <NUM> corresponds to the position where the viewfinder window of the camera module <NUM> is provided. The orthographic projection area of the aperture adjustment region <NUM> on the camera module <NUM> may be equal to or greater than the area of the viewfinder window of the camera module <NUM>, so as to ensure that all the scenes acquired by the viewfinder window of the camera module <NUM> can be adjusted through the aperture adjustment region <NUM>. In addition, the orthographic projection area of the aperture adjustment region <NUM> on the substrate <NUM> may be equal to or greater than the orthographic projection area of the first light-transmitting hole <NUM> in the substrate <NUM>, so as to ensure that light entering from the first light-transmitting hole <NUM> can be fully irradiated on the aperture adjustment region <NUM>.

When light is transmitted into the viewfinder window of the camera module <NUM> from the first light-transmitting hole <NUM>, the light-transmitting region, the aperture adjustment region <NUM>, the second light-transmitting hole <NUM>, and the third light-transmitting hole <NUM> in sequence, the guest host liquid crystals may be deflected differently to change the light transmittance of all light passing through the first light-transmitting hole <NUM>. The light transmitted into the viewfinder window of the camera module <NUM> may be fully adjusted through the aperture adjustment region <NUM>, thereby realizing the automatic adjustment of the aperture and ensuring the range of aperture adjustment.

Therefore, with the display module <NUM>, the camera module <NUM> of the electronic device of the present application may acquire different details of the same picture according to focal lengths corresponding to different aperture values of the adjusted aperture to obtain images with bright colors, thus effectively improving the photography experience of users.

In a third aspect of the present application, a photography control method is provided. The photography control method according to this embodiment of the present invention includes the following steps.

Specifically, as shown in <FIG>, in the photography control method according to this embodiment of the present invention, the electronic device first acquires an aperture adjustment instruction. The aperture adjustment instruction may be understood as an adjustment signal or an adjustment operation of a user. Then, according to the aperture adjustment instruction, the display driving chip <NUM> transmits a driving signal to the control electrode <NUM> via the conductive column <NUM> and the electrode driving wire <NUM>. The control electrode <NUM> receives the driving signal and releases a target voltage to drive the guest host liquid crystal located in the corresponding region to deflect at a certain angle, thereby realizing the adjustment of the aperture adjustment region <NUM> and obtaining the target aperture.

The control electrode <NUM> may be a plurality of aperture electrodes. When the aperture electrodes are circular, the plurality of aperture electrodes are disposed coaxially. According to a specific aperture adjustment instruction, a corresponding driving signal can be formed to adjust the corresponding aperture electrode, and the corresponding aperture electrode releases a corresponding charge-discharge voltage, whereby the guest host liquid crystal located in the corresponding region is deflected. Moreover, the guest host liquid crystal can be deflected at an angle according to different voltages, so as to adjust the aperture adjustment region <NUM> and obtain the corresponding target aperture. In the present application, the aperture electrode may be adjusted according to different arrangements and combinations, whereby the guest host liquid crystal in the corresponding annular region is deflected, and the effect of the annular aperture can be achieved. Certainly, by changing the shape of the aperture electrode, light with different shapes and areas may pass, thus achieving a certain filter effect.

Finally, by adjusting the aperture adjustment region <NUM>, the electronic device can acquire multiple frames of images as original image data, and obtain corresponding target images from the original image data according to aperture values corresponding to different target apertures. The focal length corresponding to different aperture values changes, and different details of the same picture (adjust the depth of field) may be acquired. Further, with a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of mobile phone users.

According to one embodiment of the present invention, the operation of adjusting an aperture adjustment region according to the aperture adjustment instruction to obtain a target aperture includes: determining an aperture region of the aperture adjustment region according to the aperture adjustment instruction; and controlling the deflection of a guest host liquid crystal corresponding to the aperture region to obtain the target aperture.

In some specific implementations of the present invention, the operation of controlling the deflection of a guest host liquid crystal corresponding to the aperture region to obtain the target aperture includes: applying a target voltage to the aperture region; and driving, according to the target voltage, the guest host liquid crystal to deflect by a target angle to obtain the target aperture. That is, when the control electrode <NUM> receives the driving signal, the target voltage can be applied to the corresponding aperture region, whereby the guest host liquid crystal in the corresponding region is deflected at a certain angle to obtain a target light transmittance, and light is transmitted into the viewfinder window of the camera module <NUM>, thereby obtaining an image under the target aperture.

During the photography of the camera module <NUM>, the aperture adjustment region <NUM> is adjusted according to the aperture adjustment instruction to obtain the target aperture, and the camera module <NUM> can acquire multiple frames of images as original image data according to the target aperture. Each target aperture will correspond to the corresponding aperture value, which may be found from the original image data. Further, with a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of mobile phone users.

Therefore, in the photography control method according to this embodiment of the present invention, the camera module <NUM> can acquire different details of the same picture by adjusting the aperture.

In a fourth aspect of the present application, a photography control apparatus is provided. The photography control apparatus according to this embodiment of the present invention includes an acquisition module, an adjustment module, and a photography module. The acquisition module is configured to acquire an aperture adjustment instruction. The adjustment module is configured to adjust an aperture adjustment region according to the aperture adjustment instruction to obtain a target aperture. The photography module is connected to the adjustment module. The photography module is configured to photograph according to the target aperture.

In other words, the photography control apparatus according to this embodiment of the present invention mainly includes an acquisition module, an adjustment module, and a photography module. The acquisition module can acquire an aperture adjustment instruction according to an adjustment signal or an adjustment operation of a user, and form a corresponding driving signal. The adjustment module can adjust the aperture adjustment region according to the corresponding driving signal to obtain a target aperture. The photography module is connected to the adjustment module. The photography module can photograph the target aperture according to the target aperture, so as to obtain a target image.

The photography control apparatus can acquire multiple frames of images as original image data by adjusting the aperture adjustment region <NUM> according to the corresponding driving signal through the adjustment module. Corresponding target images are obtained from the original image data according to aperture values corresponding to different target apertures. During the photography of the photography module, the focal length corresponding to different aperture values changes, and different details of the same picture (adjust the depth of field) may be acquired. Further, with a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of mobile phone users.

Specifically, the display driving chip <NUM> transmits a driving signal to the control electrode <NUM> via the conductive column <NUM> and the electrode driving wire <NUM>. The control electrode <NUM> receives the driving signal of the driving circuit and releases a target voltage to drive the deflection of the guest host liquid crystal in the corresponding region at a certain angle. The adjusted light is transmitted to the viewfinder window of the camera module <NUM>, and the target image can be obtained according to the target aperture during the photography of the camera module <NUM>. By adjusting the aperture adjustment region <NUM>, the electronic device can acquire multiple frames of images as original image data, and obtain corresponding target images from the original image data according to aperture values corresponding to different target apertures.

In some specific implementations of the present invention, the adjustment module includes a control unit and a driving unit. The control unit is configured to receive the aperture adjustment instruction and determine an aperture region of the aperture adjustment region <NUM> according to the aperture adjustment instruction. The driving unit is configured to drive the deflection of a guest host liquid crystal corresponding to the aperture region to obtain the target aperture.

That is, the adjustment module mainly includes a control unit and a driving unit. The control unit can receive the aperture adjustment instruction and transmit a driving signal. The control unit may be the display driving chip <NUM>. The driving unit can receive the driving signal, and drive the guest host liquid crystal corresponding to the aperture adjustment region <NUM> to deflect to obtain the target aperture. The driving unit may be the control electrode <NUM>. The control electrode <NUM> receives the driving signal of the driving circuit and releases a target voltage to drive the deflection of the guest host liquid crystal in the corresponding region at a certain angle.

The control electrode <NUM> may be a plurality of aperture electrodes. When the aperture electrodes are circular, the plurality of aperture electrodes are disposed coaxially. According to a specific adjustment instruction, a corresponding driving signal can be formed to adjust the corresponding aperture electrode, and the corresponding aperture electrode releases a corresponding charge-discharge voltage, whereby the guest host liquid crystal in the corresponding region is deflected. Moreover, the guest host liquid crystal can be deflected at different angles according to different voltages, so as to adjust the aperture adjustment region <NUM> to change the light transmittance, thus realizing the adjustment of the aperture to obtain the target aperture. The photography control apparatus may also adjust the aperture electrode by different arrangements and combinations according to the specific adjustment instruction, whereby the guest host liquid crystal in the corresponding annular region is deflected, and the effect of the annular aperture can be achieved. That is, by changing the shape of the aperture electrode, light with different shapes and areas may pass, thus achieving a certain filter effect.

In addition, the photography module includes an acquisition unit and a camera unit. The acquisition unit is configured to acquire multiple frames of images as original image data. The camera unit is connected to the acquisition unit and the adjustment module respectively. The camera unit is configured to obtain corresponding target images from the original image data according to aperture values corresponding to different target apertures.

Therefore, the acquisition module, the adjustment module, and the photography module of the photography control apparatus according to this embodiment of the present invention are matched to achieve the effect of variable aperture while ensuring the light transmittance. The apparatus has the advantages of small aperture volume and high aperture adjustability. During photography, the photography control apparatus of the present application realizes the automatic adjustment of the aperture through the adjustment module. The photography module can acquire different details of the same picture by adjusting the aperture. With a digital image processing technology, images with clear edges and bright colors can be obtained, thus effectively improving the photography experience of users.
