The principle and the advantages are as follows:

the driving IC module can adjust the voltage input to the liquid crystal film to a proper voltage so as to form an electric field inside the liquid crystal film, control the liquid crystal molecule curvature inside the liquid crystal film through the electric field, change the light beam offset in the advancing direction, form preset regular liquid crystal molecule movement, achieve the back and forth movement of a light focal length, and make the optical change of focusing. The focal length can be changed from far to near, from near to far or fixed by the change of voltage, so that the focusing effect is formed. The structural design of this scheme only has increased the liquid crystal film at the camera lens of original camera, need not additionally to increase the structure size, or increases another kind of other devices on the body, and the structure is more exquisite, and can reach good focusing effect equally.

Overall structure retrencies, and the light permeability is high, does not influence the formation of image effect of camera to after the circular telegram, also can not form complicated electric field, thereby control more simple and convenient.

Furthermore, a channel for the wiring of the power-on signal line is arranged on the inner wall or the outer wall of the lens. The electrified signal line is walked the line and is arranged the needs that can adapt to the multiple condition, can avoid electrified signal line to expose moreover and lead to the damage outward to influence the focusing effect of camera.

Further, the liquid crystal film and the lens are designed and packaged in an integral mode. The structure is more stable.

Examples

A variable focus imaging apparatus, substantially as shown in fig. 1 and 2: including camera lens 1, mirror seat 4, blue glass PCBA board 75 and the PCBA board 7 that sets gradually, be equipped with sensitization chip 6 on the PCBA board 7, wherein, camera lens 1, mirror seat 4 and PCBA board 7, sensitization chip 6 on the PCBA board 7 is the conventional structure that sets up of current camera module, and this scheme does not improve it, consequently does not do specific redundancy to its structure. In this embodiment, the middle of the inner cavity of the lens 1 is provided with a liquid crystal film 2 parallel to the photosensitive chip 6. The liquid crystal film 2 and the lens 1 are designed and packaged in an integral manner.

The liquid crystal film 2 includes upper and lower highly transmissive PIPI films 10, and the same type of material may be used in other embodiments. A semi-insulator material 11 is arranged between the two layers of the PIPI films 10, and liquid crystal molecules 12 are arranged in the middle of the semi-insulator material 11. In the present embodiment, liquid crystal is infiltrated on the semi-insulator material 11, and the liquid crystal is coated on the semi-insulator substrate. The two ends of the liquid crystal film 2 are electrically connected with the electric signal lines 3, the electric signal lines 3 at the same end comprise positive lines 13 and negative lines 14, and the positive lines 13 and the negative lines 14 are respectively connected with the semi-insulator material 11 through the two layers of the PIPI films 10.

And a channel for wiring the power-on signal line 3 is arranged on the inner wall or the outer wall of the lens 1. In the present embodiment, a channel for routing the energizing signal line 3 is preferably provided on the inner wall of the lens 1. The protection effect on the energizing signal line 3 is better.

The energizing signal line 3 is electrically connected with a driving IC module 8, and the driving IC module 8 is arranged on the PCBA board 7. In this embodiment, the driving IC module 8 and the photosensitive chip 6 are both disposed on the PCBA board 7, and the PCBA board 7 is connected and fastened with the main PCBA board 7 end outside through the connector 9 disposed thereon to form a power supply signal path. The driving IC module 8 controls the voltage between the positive electrode line 13 and the negative electrode line 14 of the power-on signal line 3 according to a control signal at the end of the main PCBA board 7, and the voltage value ranges from 1V to 12V.

The scheme mainly utilizes the known property that liquid crystal molecules 12 in the liquid crystal film 2 have different refractive indexes in different directions, liquid crystal permeates into the semi-insulator material 11, and is coated on the semi-insulator substrate, so that when voltage is communicated with the semi-insulator material 11 in the liquid crystal film 2, different positions of the semi-insulator material 11, which are far away from a power supply point, have different voltages. Therefore, the distance areas are different, the resistance values are different, and the liquid crystal molecules 12 obtain different voltages and different bending directions, so that regular refraction incidence is formed, and the optical phenomenon of focusing is generated. For example, as shown in fig. 2, when the power is supplied at 6V, the center area of the liquid crystal film 2 is 3V and the edge of the liquid crystal film 2 may be 5V due to the influence of the resistance. Therefore, the regular refraction incidence of the liquid crystal molecules 12 can be controlled by adjusting and changing the voltage, thereby achieving good focusing effect.
