Alternatively, the second electrode 6 may be eliminated, and one side of the liquid crystal layer 5 is connected to the first electrode 4, and the other side is grounded, so that the light transmittance of the liquid crystal layer 5 can be changed by adjusting the voltage value of the first electrode 4.

As shown in fig. 2, the camera module may be formed by combining the filter assembly 100, the lens 200, and the photosensitive chip 300, and the filter assembly 100 may be disposed between the lens 200 and the photosensitive chip 300.

Specifically, since the filter assembly 100 includes the liquid crystal layer 5, the filter assembly 100 may be manufactured in a manner that is referred to as a manner of manufacturing a liquid crystal screen in the prior art, and this embodiment of the present application is not particularly limited thereto.

Further, the liquid crystal layer 5 may include liquid crystal molecules, the liquid crystal molecules have a characteristic of electrically controlling the refractive index to be variable, and when the voltage difference received at two sides of the liquid crystal layer 5 changes, the orientation of the liquid crystal molecules changes, so that the refractive index of the liquid crystal layer 5 can be changed, that is, the optical path of light is changed, and the auto-focusing function of the camera module can be realized.

Specifically, the cross-sectional shape of the liquid crystal molecules may be an ellipse, a circle, a rectangle, etc., and this embodiment of the present application is not particularly limited as long as it satisfies the difference in refractive index of the liquid crystal molecules in different directions. The following description will be given by taking the example in which the cross-sectional shape of the liquid crystal molecules is an ellipse, and other reference arrangements may be made: the refractive index of the liquid crystal molecules may be the largest when the long axes thereof are perpendicular to the plane of the first substrate 1, the refractive index of the liquid crystal molecules may be the smallest when the long axes thereof are parallel to the plane of the first substrate 1, the refractive index of the liquid crystal molecules may be positively correlated with the alignment direction angle (the angle between the long axes and the plane of the first substrate 1), and the magnitude of the alignment direction angle may be correlated with the electric signal between the first electrode 4 and the second electrode 6.

Specifically, the first substrate 1, the second substrate 8, the filter layer 2, the first electrode 4, the second electrode 6, and the liquid crystal layer 5 all have good optical transparency, and the filter layer 2 can control the transmission of light with a specific wavelength.

According to still other embodiments of the present application, the first electrode 4 may be provided with a plurality of independently disposed first electrode units 41, the second electrode 6 may be correspondingly provided with a plurality of independently disposed second electrode units 61, and the liquid crystal layer 5 may include a plurality of liquid crystal regions 51; the first electrode units 41 and the second electrode units 61 are arranged in one-to-one correspondence; the liquid crystal region 51 is correspondingly disposed between the first electrode unit 41 and the second electrode unit 61; in the case where an electrical signal between the first electrode unit 41 and the second electrode unit 61 is changed, the transmittance of the corresponding liquid crystal region 51 may be adjusted.

In the embodiment of the present application, the liquid crystal regions 51 are correspondingly disposed between the first electrode unit 41 and the second electrode unit 61, and when the electrical signal between the first electrode unit 41 and the second electrode unit 61 changes, the transmittance of the corresponding liquid crystal regions 51 can be adjusted, and when the optical filter assembly 100 is applied to the image capturing technology, by adjusting the transmittance of different liquid crystal regions 51, the phenomena of aberration, distortion, field curvature, and uneven brightness can be avoided, so as to optimize the final imaging quality and improve the image capturing effect.

As shown in fig. 5, the liquid crystal layer 5 may include four liquid crystal regions 51: n1, N2, N3, N4, N1, N2, N3, and N4 correspond to different electrical signals, for example, from N1 to N2, the light transmittance of the corresponding liquid crystal region 51 may be sequentially decreased, sequentially increased, and alternately changed, and specifically may be determined according to the brightness of the light collected by the lens 200, so that the brightness uniformity of the imaging surface of the photosensitive chip 300 may be achieved, and the imaging effect may be improved.

Specifically, since the light transmittances of different liquid crystal regions 51 can be independently adjusted, the filter assembly 100 can realize the function of an iris diaphragm, so that the camera module can realize multifunctional shooting effects such as main shooting, wide-angle shooting, telephoto shooting, and the like.

Alternatively, the filter assembly 100 may include the first alignment film 3 and the second alignment film 7; the first alignment film 3 may be provided between the filter layer 2 and the first electrode 4, and the second alignment film 7 may be provided between the second electrode 6 and the second substrate 8.

In this application embodiment, adopt first orientation film 3 and second orientation film 7, can control the light that is unanimous rather than the polarization state and see through, can reduce the crosstalk between the different colour light, at the shooting in-process, can obtain the color image of no crosstalk, improve the shooting effect of the module of making a video recording.

Specifically, the orientation of the first orientation film 3 and the orientation of the second orientation film 7 may be parallel, perpendicular or at any included angle, and may be specifically set according to actual requirements, which is not specifically limited in the embodiment of the present application.

Alternatively, the first alignment film 3 may be provided with a plurality of first polarization regions 31, the second alignment film 7 may be correspondingly provided with a plurality of second polarization regions 71, and the filter layer 2 may be provided with a plurality of color channels 21; the first and second polarization regions 31 and 71 may be disposed corresponding to the color channels 21.

In this application embodiment, the light that passes through color channel 21 can pass through first polarization zone 31 and second polarization zone 71 in proper order, under the cooperation of first polarization zone 31 and second polarization zone 71, can avoid the crosstalk between the different colour light, improves the shooting effect of the module of making a video recording.

Specifically, the filter layer 2, the first alignment film 3, the first electrode 4, the second electrode 6, and the second alignment film 7 are all disposed correspondingly, and the color channels 21 of the filter layer 2 may be arranged periodically, as shown in fig. 3A, which shows one arrangement period, where one arrangement period includes four color channels 21: an R channel, two G channels, and a B channel. As shown in fig. 3B, the first alignment film 3 includes four corresponding first polarizing regions 31, and each first polarizing region 31 is oriented as shown by the direction of the arrow in fig. 3B; as shown in fig. 3C, the second alignment film 7 includes four corresponding second polarization regions 71, and each second polarization region 71 is aligned as shown by the arrow direction in fig. 3C. As shown in fig. 3D, the projections of the first electrode unit 41 and the second electrode unit 61 overlap, and the electric signal between the first electrode unit 41 and the second electrode unit 61 includes: u1, U2, U3, and U4, and U1, U2, U3, and U4 are respectively provided corresponding to the four color channels 21.

Specifically, U1 may control the rotation of liquid crystal molecules in the liquid crystal region 51 corresponding to the R channel, U2 and U3 may control the rotation of liquid crystal molecules in the liquid crystal region 51 corresponding to the two G channels, and U4 may control the rotation of liquid crystal molecules in the liquid crystal region 51 corresponding to the B channel, respectively. Since the liquid crystal molecules have the ability to rotate the polarization direction of the incident light, changing the values of U1, U2, U3, and U4 can change the rotation angle of the liquid crystal molecules, which in turn can change the rotation angle of the polarization direction of the incident light, and achieve periodic cutoff of the color channel 21.

For example, assuming that the orientations of the first alignment film 3 and the second alignment film 7 are perpendicular to each other, a voltage U1 is applied to the liquid crystal region 51 corresponding to the R channel, the liquid crystal molecules rotate, so that the polarization direction of the light is rotated by 90 degrees, and the light can be irradiated to the photo chip 300 through the second alignment film 7. No voltage is applied to the liquid crystal regions 51 corresponding to the G channel and the B channel, that is, U2-U3-U4-0, liquid crystal molecules in the liquid crystal regions 51 corresponding to the G channel and the B channel do not rotate, and the polarization direction of the corresponding light does not rotate, so that the light corresponding to the G channel and the B channel cannot be irradiated to the photosensitive chip 300 through the second alignment film 7, which realizes the periodic cut-off of the different color channels 21, that is, the light corresponding to the R channel, and the photosensitive chip 300 can obtain a monochromatic image, thereby avoiding crosstalk between the G channel and the B channel. The monochromatic images of the G channel and the B channel can be obtained according to time sequence, and the monochromatic images with multiple frame rates can be fused into a final color image at the later stage. The matching of the voltage control and the response speed of the liquid crystal molecules is ensured, and the three-color image of the same scene can be obtained in a shorter time interval.

Alternatively, the plurality of liquid crystal regions 51 may be concentrically disposed. In the embodiment of the present application, the plurality of liquid crystal regions 51 are concentrically arranged, so that the light transmittance of each liquid crystal region 51 is controlled, and the zoom function of the camera module is realized.

Specifically, the light transmittance of the liquid crystal region 51 can be controlled, the variable aperture can be realized, the number of apertures can be flexibly adjusted, and different shooting functions such as main shooting, wide angle, telephoto and the like can be realized. When the number of apertures is set, the liquid crystal layer 5 may be divided into a plurality of liquid crystal regions 51 symmetrically outward around the physical center of the liquid crystal layer 5 as the origin. The first electrode unit 41, the second electrode unit 61 and the liquid crystal area 51 can be correspondingly arranged in different liquid crystal areas 51, and the aperture size of the light-transmitting hole can be adjusted by adjusting the electric signal between the first electrode unit 41 and the second electrode unit 61, so that the iris diaphragm is realized.

As shown in fig. 4, the structure of the liquid crystal layer 5 may be circular, and along the radius direction thereof, the liquid crystal layer 5 may be divided into two liquid crystal regions 51: a circular region and an annular region. When the electric signal between the first electrode unit 41 and the second electrode unit 61 is set to U5, light can pass through; when the electrical signal between the first electrode unit 41 and the second electrode unit 61 is U6, light may not pass through, so as to realize "on" and "off" of light. When the electrical signals of the circular area and the annular area are both U5, the light-transmitting aperture is large; when the electrical signal corresponding to the circular area is U5 and the electrical signal corresponding to the annular area is U6, the aperture of the light-transmitting hole is small. Fig. 4 is only illustrated by taking the number of the apertures as 2, and other cases may be referred to, which is not specifically limited in the embodiment of the present application.

Alternatively, the shape of the liquid crystal region 51 may include: at least one of circular, rectangular, annular, and irregular polygonal.

In the embodiment of the present application, the shape of the liquid crystal region 51 includes: at least one of a circle, a rectangle, a ring, and an irregular polygon can improve the diversity of the arrangement of the liquid crystal region 51, and realize the light holes of different shapes.

In still other embodiments of the present application, the filter assembly 100 may include a controller, which may be electrically connected to the first electrode unit 41 and the second electrode unit 61, respectively, and may be used to adjust the magnitude of the electrical signal between the first electrode unit 41 and the second electrode unit 61.

In the embodiment of the present application, the controller is adopted to adjust the magnitude of the electrical signal between the first electrode unit 41 and the second electrode unit 61, which is convenient and fast, and the sensitivity is high.
