It should be noted that adjustable lens (Tunable lens, T lens) mould involved in the embodiment of the present invention
Block be it is a kind of the module of light focusing or diverging is realized according to control voltage, as shown in figure 1, Fig. 1 is adjustable lens T
The encapsulation schematic diagram of lens modules, it is mainly made up of the T lens core components 102 at surrounding package circuit 101 and center.Its
In, the surrounding package circuit in adjustable lens T lens modules have 4 pins (a positive level, a negative pole, one group of both positive and negative polarity
Spare interface) it is connected with the pcb board of camera module, realized to adjustable lens T lens modules by both positive and negative polarity pin powered
Drive control.
Further, as shown in Fig. 2 the core component 102 of adjustable lens T lens modules is main by glass substrate 201,
High molecular polymer 202, glass film 203, and piezoceramics film 204 is constituted.Adjustable lens T lens modules it is main
Operation principle is as follows：When supplying different voltages using the driving chip in surrounding package circuit 101, piezoceramics film 204
Deformation can be produced, so that, different refractive indexes are produced, change the focus point of light, so as to realize the focusing or diverging of light.
As shown in Fig. 2 a- Fig. 2 c, adding the degree of crook difference produced when different voltages causes to differ the ability for converging light
Sample, wherein, Fig. 2 a are schematic diagram when adding 0V voltages, and Fig. 2 b are schematic diagram when adding 5V voltages, and Fig. 2 c are plus 20V voltages
When schematic diagram, when driving chip to T lens modules provide voltage be 0V when, as shown in Figure 2 a, light pass through adjustable lens
During T lens modules, light path does not change, and when driving chip provides voltage for 5V to adjustable lens T lens modules, such as schemes
Shown in 2b, when light passes through adjustable lens T lens modules, light path changes, and directional light is changed into gathering light, works as driving chip
When the voltage provided to adjustable lens T lens modules increases to 20V, as shown in Figure 2 c, light gathers amplitude increasing, thus may be used
Find out, with the increase of voltage amplitude, the focal length of adjustable lens T lens modules reduces.By control voltage size, Ke Yigai
Become focus, realize automatic focusing.The understanding of popular image, that is, be comparable to before camera, with a convex lens glasses, lead to
Cross energization to drive to control the number of degrees of glasses, voltage is higher, and the number of degrees are higher, so as to be solved by a number of degrees for continuous variable
The problem that camera is seen clearly.
Same reason, when driving chip provides negative voltage, such as -5V, -20V to adjustable lens T lens modules, pressure
Electroceramics film 204 can produce deformation, and when now light passes through adjustable lens T lens modules, light path changes, directional light
Become diverging light, the understanding of popular image is comparable to before camera with a concavees lens, and can be by control
Voltage drives, the degree of adjustment light diverging, equivalent to the number of degrees that have adjusted concavees lens.
Further, the cardinal principle of the camera module in the embodiment of the present invention is based on adjustable lens T Lens modules
Technical characteristic, as shown in Figure 2 d, when to adjustable lens T Lens modules provide a forward voltage when it can play convergence
The effect of light, now equivalent to a convex lens, when a negative voltage is provided to adjustable lens T Lens modules, its energy
Enough play a part of divergent rays, now, equivalent to a concavees lens, according to most basic optical principle, concave, convex lens can
Play a part of zoom.
In concrete application, during driving chip supply adjustable lens T Lens modules difference voltage, piezoceramics film and glass
Glass film is deformed upon, and so as to generate different refractive indexes, changes the focus point of light.Different voltage causes that piezoelectricity is made pottery
Porcelain film is different with the flexibility of the generation of glass film, within the specific limits, as voltage increases, piezoceramics film and glass
Glass film bends degree increases, and causes the change of focal length.
